BACKGROUND OF INVENTION
Field of Invention
The present invention is directed toward improvements in building construction, and more particularly, the prefabrication and construction of multi-story buildings made from wood, lumber and wood-based products, offering improved defense against fire, while mitigating the adverse effects of climate change caused by enhanced build-up of greenhouse gases about the Earth's atmosphere.
BRIEF DESCRIPTION OF THE STATE OF KNOWLEDGE IN THE ART
The Earth's surface supports relatively mild and stable temperatures because its atmosphere contains a thin layer of gases that cover and protect the planet from solar radiation.
As illustrated in FIG. 1A, the Earth is constantly bombarded with enormous amounts of radiation, primarily from the sun. This solar radiation strikes the Earth's atmosphere in the form of visible light, plus ultraviolet (UV), infrared (IR) and other types of radiation that are invisible to the human eye. UV radiation has a shorter wavelength and a higher energy level than visible light, while IR radiation has a longer wavelength and a weaker energy level. According to NASA, about 30 percent of the radiation striking Earth's atmosphere is immediately reflected back out to space by clouds, ice, snow, sand and other reflective surfaces. The remaining 70 percent of incoming solar radiation is absorbed by the oceans, the land and the atmosphere. As they heat up, the oceans, land and atmosphere release heat in the form of IR thermal radiation, which passes out of the atmosphere and into space. It is this equilibrium of incoming and outgoing radiation that makes the Earth habitable, with an average temperature of about 59 degrees Fahrenheit (15 degrees Celsius). Without this atmospheric equilibrium, Earth would be as cold and lifeless as its moon, or as hot as Venus. The moon which has almost no atmosphere, is about minus 243 F (minus 153 C) on its dark side. Venus, on the other hand, has a very dense atmosphere that traps solar radiation and supports an average temperature of about 864 F (462 C).
The exchange of incoming and outgoing solar radiation that warms the Earth is often referred to as the “greenhouse effect” because a greenhouse works in much the same way. Incoming UV radiation from the Sun easily transmits through the glass walls of a greenhouse and is absorbed by the plants and hard surfaces inside. Weaker IR radiation, however, has difficulty transmitting through the glass walls and is trapped inside, thus warming the greenhouse. This effect lets tropical plants thrive inside a greenhouse, even during a cold winter.
As illustrated in FIG. 1B, carbon dioxide (CO2) and other greenhouse gases act like a blanket, absorbing and preventing IR radiation from escaping into outer space. The net effect is the gradual heating of Earth's atmosphere and surface, a process known as global warming. These greenhouse gases include water vapor, CO2, methane (CO4), nitrous oxide (N2O) and other gases, according to the Environmental Protection Agency (EPA).
The greenhouse effect, combined with increasing levels of greenhouse gases and the resulting global warming, is expected to have profound implications, according to a near-universal consensus of scientists. If global warming continues unchecked, it is believed that this will cause significant climate change, a rise in sea levels, increasing ocean acidification, extreme weather events and other severe natural and societal impacts, according to NASA, the EPA and other scientific and governmental bodies.
Many scientists today agree that excess greenhouse gases generated by mankind have caused damage to the Earth's atmosphere and climate, that is now past the point of no return. To many scientists, there are three options going forward: (i) do nothing and live with the consequences; (ii) adapt to the changing climate, which includes things like rising sea level and related flooding; or (iii) mitigate the impact of climate change by aggressively enacting policies that actually reduce the concentration of CO2 in the atmosphere.
Those actively involved in the building design and construction industry can make a choice to use wood-based building materials over steel and concrete, wherever possible, to help sequester CO2 in lumber and reduce the concentration of CO2 in the atmosphere. Promoting the use of wood as a building material can be attractive to many, and could develop significant building trends, like building skyscrapers from mass timber building technologies, with proper amounts of concrete and steel, especially if there are adequate incentives put in place by the government.
To understand how CO2 is collected and sequestered by growing trees and ultimately stored in lumber and wood products, it is important to understand how the element carbon is stored and cycled in trees, and for the life of wood products.
As illustrated in FIG. 3, elemental carbon is represented by the symbol ‘C’ and is the 6th element in the Periodic Table of Elements, with an atomic number of 6 and an atomic mass of 12.001. It is a non-metal and the fourth most abundant element in our solar system, only surpassed by hydrogen, helium and oxygen. Carbon can take the form of coal, charcoal, and diamonds, and also forms the major component of all living things, including plants and trees. At atmospheric pressure, carbon occurs naturally as either a solid or a gas. The melting/sublimation point of carbon is the highest of all naturally occurring elements at 3550° C.
Carbon is cycled through ecosystems in several different forms. It has a tendency to be attracted to oxygen and form gaseous compounds such as carbon dioxide (CO2) and carbon monoxide (CO) which, in high concentrations, can be considered air pollutants and play a role in climate change. Carbon dioxide gas can be removed from the atmosphere by trees through photosynthesis. As illustrated in FIG. 4, this process involves plant cells converting the carbon from carbon dioxide to a solid form in sugars (the carbohydrates glucose and starch) that can be stored in leaves, stems, trunks, branches and roots, and contribute to tree growth. Oxygen is released back into the atmosphere as a by-product of photosynthesis which animals depend upon for survival. How carbon storage in trees and wood products occurs in nature is illustrated by the chemical formula for photosynthesis:
Starch is also stored in reproductive tissue, including flowers, fruit, nuts, pods or cones, while glucose is used in respiration to help keep the tree alive. Cellulose illustrated in FIG. 4 is another sugar manufactured by the plant, and is particularly important in plant cell walls to help maintain structure and keep plants upright. Wood is around 40% cellulose.
As shown in FIG. 5, the Carbon Cycle demonstrates the various phases of carbon through living things, the soil, water and atmosphere. If the carbon cycle were in equilibrium, the rate at which carbon is removed from stores would equal the amount being taken out of the atmosphere. The current concern about the carbon cycle is that it is considered to be out of equilibrium in response to human intervention.
The burning of fossil fuels high in carbon has disturbed the natural balance of the cycle and enhanced the rate at which carbon is returned to the gas phase. This increase in carbon gas in the atmosphere, particularly as carbon dioxide CO2 and methane CH4, has been found to contribute to global warming and is referred to as the ‘man-made greenhouse effect’ discussed above, the process where greenhouse gases trap infrared radiation in the atmosphere and cause the earth to warm, as illustrated in FIGS. 1A and 1B.
Carbon constitutes approximately 50% the dry mass of trees and when wood from these trees is used to produce wood products, the carbon is stored for life in that product. For framing in our homes, this carbon storage life is around 100 years, around 30 years in furniture products, around 30 years in railroad ties, and around 6 years in pallets and paper. Carbon stored in wood is only released back to the atmosphere when the wood product is burnt or decays.
The amount of carbon in sawn timber logs can be calculated using average rates of recovery after processing which is estimated at around 35% for hardwoods such as eucalypts, and 50% for softwoods such as pine. The standard moisture content for air-dried timber (and wood products) is 12% which is equivalent to stating the 88% of moisture has been removed from the timber. To calculate the CO2 in construction timber, one must ascertain the following variable parameters:
- (i) the air dry mass of the timber log,
- (ii) the percentage of moisture removed from the timber log, and
- (iii) the recovery rate (% of carbon in timber after processing—estimated at around 35% for hardwoods such as eucalypts, and 50% for softwoods such as pine).
A reliable formula for estimating the quantity of CO2 sequestered in construction timber [kg] is provided by the equation below:
CO2 sequestered in construction timber [kg]=air dry mass of saw log (kg)×88% (oven dry mass)×50% (carbon %)×3.67×recovery rate (%),
- where the factor of 3.67 is used to determine the equivalent amount of carbon dioxide from knowledge of the carbon figure.
Example: For a 150 kg white cypress saw log (softwood) seasoned in a timber yard then processed into square posts, the amount of carbon sequestered in the timber posts=150 kg×88%×50%×3.67×50%=84.8 kg carbon dioxide. To compute the quantity of carbon in the wood log [kg], simply divide 84.8 [kg] of carbon dioxide by the factor 3.67 to provide 22.98 [kg] of carbon.
When working with lumber beams of specified dimensions, the same mass-based carbon-estimating formula for timber logs recited above can be readily modified and adapted for with lumber beams of specified dimensions, EWPs of various types, mass timber panels, and wood-framed panels.
Clearly, the use of fire-protected wood products in the building construction industry can have a positive impact on CO2 sequestration, and the mitigation of negative effects from climate change, and possibly driving the population in the right direction towards environmental sustainability.
Also, there is a clear and growing need for new and improved technologies that will enable enabling architects, builders and owners of wood-framed and mass timber buildings to account and receive proper credit for designing and building with CO2-absorbing wood materials, over CO2 producing materials such as concrete and steel, and thereby improve our living environment and provide viable pathways toward environmental sustainability and protection for future generations, supported by compelling economic incentives that will promote positive and life-supportive carbon-collecting industrial activity, while overcoming the shortcomings and drawbacks of prior art methods and apparatus.

The job-site fire-protection liquid spray process of the present invention supported by the system network 100 at each registered wood-framed and mass timber building 111A is described in FIGS. 49 through 67L, and hereinafter in the Patent Specification.
The just-in-time wood-framed and mass timber factory system 130 with production lines 131 for producing Class-A fire-protected carbon-quantized pre-fabricated building components, is described in FIGS. 68A through 81F.
FIG. 7 represents the cloud-based carbon-quantization engine, system and process 500 of the present invention is supported by the system network 100 of the present invention shown in FIG. 6 for estimating and recording (i.e. quantizing) quantities of carbon mass (measured in kg or tons) securely stored in Class-A fire-protected wood-framed and mass-timber building components, assemblies and buildings on construction job-sites, and in prefabrication factory environments. As will be described in greater detail hereinafter, the carbon quantization engine 500 uses computational and information resources supported within the data center 110 of the network, well as the mobile or remote computing systems 117, 137, creating and sending carbon quantization requests to the data center 110 over the network, and generating and display fire protect carbon unit (FPCU) reports and product labels for application to fire-protected carbon-quantized wood-frame and mass timber building components, and composite building systems constructed therefrom, to provide a specific carbon footprint for the constructed wood framed and/or mass timber building.
As shown in FIG. 7, the carbon quantization engine 500 estimates the quantity of carbon mass (e.g. measured in kg or tons) that is stored in fire-protected wood products used in GPS-specified wood framed and mass timber buildings under construction, or during prefabrication.
As shown in FIG. 7, the carbon-quantization engine 500 of the present invention comprises: a carbon calculation/estimation module 500A for receiving requests to estimate/calculate the amount of carbon mass (measured in kilograms or kg, or Tons) stored in a specific piece and species of dimensioned wood/lumber, or wood-framed panel or mass timber building component 132, typically used in a adequately dried state with a particular low moisture content within the fiber of the wood; a GPS and time and data stamping module 500D for applying GPS, time and data stamping to each request for fire-protected carbon unit (FPCU) quantization on the network 100; a wood species database 500B containing information on (i) the amount of carbon in kg stored in (or recoverable from) specific species of wood of a specific mass at a particular moisture content percentage, (ii) the wood species' “rate of carbon recovery” (expressed as a percentage weight, e.g. 0.85), and (iii) the amount of mass in a board foot length of a particular species of dimensioned wood product, at a specific moisture content; a building design and BIM (building information modeling) database 500C containing information models and information elements (e.g. lumber tables of specific wood species, dimensions, and board footage for each kind of lumber material to be used to construct each structural element specified in the building design) and specifying the quantities of wood (in terms of dimensions and board feet measurements and parameters) used in the construction of a specific building located at given address and set of GPS coordinates; and a fire protected carbon unit (FPCU) credit processor 500E for calculating any one or more different credits (e.g. tax credits or industry credits) based on a specific amount of fire-protected carbon units (FPCUs) quantized by the system network 100, and including a credit table with formulas for converting each FPCU figure measured in [kg] or [Ton] into a FPCU-based credit measured in terms of a specific economic value within another system of value (e.g. US Dollars $) or based on another and different economic system, token system, or other value system that may be devised and adopted by a particular group of people.
As shown, each piece of fire-protected wood or lumber or building component, or completed building section within a wood-framed building that has been sprayed with CFIC liquid, is identified by a mobile or stationary computing system 117, 137. This identification step is typically achieved by reading a unique code symbol or code symbol/RFID tag (132) applied to the wood product, or barcoded/RFID-tag 300 applied to a completed wood-framed building section. The identified item of fire-protected wood is registered with the system network, under a specific carbon quantization project. Once the fire-protected wood component is identified and provided to the carbon estimation/calculation module 500A of the carbon quantization engine 500, the wood species database 500B and building design and BIM database 500C are accessed as required to compute the amount of carbon mass stored in the identified piece of fire-protected wood, or wood-framed or mass timber building component, or completed fire-protected wood-framed building section, using very simple formulas well known in the art and described in detail in the WoodWorks™ Carbon Calculator: References & Notes (2018), incorporated herein by reference in its entirety. The WoodWorks™ The WoodWorks Carbon Calculator tool estimates the total wood mass in a building and the associated carbon impacts. In the Woodworks™ Carbon Calculator, “carbon impacts” refer to both (i) the amount of carbon stored in the wood building materials, and (ii) the amount of greenhouse gas emissions (GHGs) avoided by choosing wood instead of another more GHG-intensive, non-wood material.
In the illustrative embodiment, carbon-quantization engine 500 represented in FIGS. 7, 8A, 8B and 9 is implemented using an object-oriented software engineering environment supported by the web, application and database servers of the data center 110, the mobile and stationary computing systems 137, 138, data acquisition engines 600 installed in factory environments 130, and the global TCP/IP infrastructure of the Internet supporting the basic functions described below. The real-time fire-protected carbon-quantization engine 500 of the present invention is adapted and configured for estimating (i.e. quantizing) and recording the mass quantity of fire-protected carbon naturally captured and sequestered in wood products used in wood-framed and mass timber building components, assemblies and buildings, after being treated and fire-protected with clean fire-protection chemicals on construction job sites, as well as in prefabricated factory environments, as described and specified here.
FIG. 8A shows the system architecture of the carbon-quantization engine (i.e. system) of the present invention 500 supported by the network 100 shown in FIG. 1, and preferably implemented in the distributed computing and communication environment of the data center 110 and mobile computing systems 117, 137 and TCP/IP infrastructure. As shown, the an I/O data handling module 500F receives requests for carbon quantization and accompanying object identifying codes (132, 300, etc.) from scanning devices 117, 137 and other data acquisition systems 600 supplied through the TCP/IP 116 and processed by data processing modules 500A and 500D, with the support of databases 500B and/or 500C. The estimated fire-protected carbon units (FPCUs) are stored in the database storage module 500G shown in FIG. 8 which may be stored in the data center 110 and/or on other servers around the world.
Requests to compute FPCU quantities in identified wood-framed and mass timber building components may be made from any location where Class-A fire protection may be delivered using the system and network of the present invention. Once made using the mobile system 117, 137 and other networked computing systems, these requests will be automatically and transparently processed by processing modules 500A and 500D so as to compute FPCU figures that are GPS, time and date stamped and indexed to the code and GPS-specified wood-based building component, or prefabricated building system or constructed building. Ultimately, these indexed FPCU figures will be stored in the database storage module 500G and made accessible to the mobile applications supported by the system network 100 of the present invention, as reflected in the GUIs screens shown in the Drawings.
FIG. 8B shows the automated process supporting the real-time estimating and recording (i.e. quantization) of the quantity of fire-protected carbon (mass) units (FPCUs) naturally stored in wood products used in wood-framed and mass timber building components, assemblies and buildings. Typically, a carbon quantization request is initiated after a specific piece of wood, or wood assembly, has been treated and Class-A fire-protected with clean fire-protection chemical (CFIC) liquid on construction job sites, as well as in a prefabricated wood-framed or mass timber factory environment. However, it is understood that carbon quantization engine 500 can be requested over the network and used at any time before, during or after the application of Class-A fire-protection to wood building material, so as to quantize the amount of carbon mass stored in a specific wood-framed building, mass timber building, or any particular building component used to construct the same. Expectedly, the timing of such carbon quantization requests will differ and vary from application to application, and will be timed to meet the demand for knowing how much carbon mass has been protected by Class-A fire protection, and when and where this Class-A fire protection occurred, and by whom, using what methods and standards, otherwise required to certify the quality of protective encapsulation about the quantized carbon mass stored in a specific article of wood.
As indicated in FIG. 8B, the carbon quantization process of the present invention comprises a number of steps, namely: (a) requesting building construction companies, registered on the network, to upload their BIM models and wood/lumber construction parameters for GPS-indexed wood-framed and mass timber building projects to the network database in the data center 110, typically supplied from industry leading CAD and CIM software systems, such as AUTODESK® and building construction products such as RIVET and others; (b) supplying input parameters to the computational model being maintained—namely: (i) species of wood being fire-protected, (ii) estimated amount of dry mass of wood used in the fire-protected wood product or assembly, (iii) percentage moisture removed from the wood species, (iv) carbon recovery rate % in dry mass of wood, and (v) the unique identifier code applied to the fire-protected wood being carbon-quantized; (c) using computational models for determining quantity of carbon stored in a particular quantity of a wood species, maintained under specific conditions; and (d) storing in the network database, computed fire-protected carbon unit (FPCU) figures representative of the quantity of carbon that is stored in the fire-protected wood product(s) identified by the input object identifying code. Typically, the computational model will seek to estimate through calculation, the total mass (in Tons) of dry wood mass of specific species of wood being used to construction a specific building specified in a given BIM computer model. Typically, a given building construction project can be decomposed into the quantity of board feet or square fee of specific species of wood having specific dimensions, and from such board footage and square feet measurement parameters, the system can calculate the dry mass of the quantity of wood to be used on the construction project. Such dry mass measures can be used to estimate how much carbon material is contained in the quantity of dry mass of a specific wood species. Totally the total carbon mass quantities for the pieces of wood used to construction a specified/identified building component, the amount of fire-protected carbon units (in Tons) can be calculated in a straightforward manner.
An example computation model for quantizing the FPCU in construction timber used in a wood-framed building is: (stored in construction timber [kg] air dry mass of timber (kg)×88% (oven dry mass)×50% (carbon %)×recovery rate (%),
When working with specific quantity of board feet of a particular species of lumber of specified dimensions, the same mass-based carbon-quantizing formula for construction timber recited above can be readily modified and adapted for dimensioned lumber beams, EWPs, mass timber panels, and wood-framed panels using appropriate volumetric conversion formulas that will convert a specific length of dimensioned lumber into a mass equivalent mount of dry mass of such species of lumber.

FIG. 9 describes the steps carried out when practicing the method of estimating and recording (i.e. quantizing) the quantities of fire-protected carbon stored in Class-A fire-protected wood-framed and mass-timber building components, assemblies and buildings on construction job-sites, and in prefabrication factory environments.
As shown in FIG. 9, the method comprises: (a) deploying barcode/RFID-tag (i.e. code) scanners/readers 117, 137 for identifying Class-A fire-protected wood products and assemblies used in a wood-framed or mass timber building on a construction site, or in a factory environment; (b) maintaining a first database 500B for storing parameters characterizing the a particular species of wood including the percentage of carbon stored in a specific quantity of the species of wood under certain circumstances used in various construction projects, or produced in a lumber factory or prefabricated-building factory environment; (c) maintaining a second database 500C for storing parameters characterizing the quantity and quality of specific species of dimensioned wood and engineered wood products (EWPs) used in building specific wood-framed or mass timber building designs under construction using BIM computer systems; (d) using a barcode/RFID-tag scanner/reader 117, 137 or data acquisition engine 600 for identifying fire-protected wood products and assemblies used in a wood-framed or mass timber building, either built on a wood-framed building or mass timber construction job site, or being prefabricated in a factory environment for delivery and installation on a destination construction site; and (e) using scanned identifiers of Class-A fire-protected wood products and/or assemblies, and the data maintained in the first and/or second databases (500B and 500C) on the network to calculate the quantity of carbon mass stored in the Class-A fire-protected wood used in the GPS-specified buildings and/or building components under construction on construction sites or factory environment. The output of this carbon-quantization process is to produce the amount of carbon mass stored in Class-A fire-protected wood using the system and network of the present invention. Such mass quantities for carbon can be converted to equivalent amounts of carbon dioxide CO2 sequestered by growing trees to produce this equivalent amount of fire-protected carbon units (FPCUs) measured in kg or tons, or other suitable units of mass measurement.

Specification of the Method of and Apparatus for Producing a Bundle of Class-A Fire-Protected Lumber Produced in Accordance with the Principles of the Present Invention
While most fires start small, they often spread rapidly onto surrounding flammable surfaces. Before long, the phenomenon of flash over occurs, where superheated gases cause a whole room to erupt into flame within minutes. Class-A fire-protected lumber of the present invention, as shown in FIG. 18, bears a clear or transparent surface impregnation formed by dip-infusion of lumber pieces in clean fire inhibiting chemical (CFIC) liquid, preferably Hartindo AF21 Total Fire Inhibitor, developed by Hartindo Chemicatama Industri of Jakarta, Indonesia, and commercially-available from Newstar Chemicals (M) SDN. BHD of Selangor Darul Ehsan, Malaysia http://newstarchemicals.com/products.html. When so treated, Class-A fire-protected lumber products will prevent flames from spreading, and confine fire to the ignition source which can be readily extinguished, or go out by itself.
The primary chemical constituents of Hartindo AF21 include: monoammonium phosphate (MAP) (NH4H2PO4); diammonium phosphate (DAP) (NH4)2HPO4; ammonium sulphate (NH4)2SO4; urea (CH4N2O); ammonium bromide (NH4Br); and tripotassium citrate C6H5K3O7. These chemicals are mixed together with water to form a clear aqueous solution that is environmentally-friendly (i.e. clean) non-toxic, but performs extremely well as a total fire inhibitor. In the presence of a flame, the chemical molecules in the CFIC-infusion formed with Hartindo AF21 liquid into the surface of the fire-protected lumber, interferes with the free radicals (H+, OH−, O) involved in the free-radical chemical reactions within the combustion phase of a fire, and breaks these free-radical chemical reactions and extinguishes the fire's flames.
FIG. 18 shows a bundle of Class-A fire-protected carbon-quantized finger-jointed lumber 29 produced using the method of and apparatus of the present invention. FIG. 19 shows an automated lumber factory system 20 for continuously fabricating wrapped and packaged bundles of Class-A fire-protected finger-jointed lumber product 29 in a high-speed manner, in accordance with the principles of the present invention. However, it is understood that this automated factory and production methods can be used to treat and protect solid wood and timber products, as well, so as to produce Class-A fire-protected solid wood products (e.g. studs, beams, boards, etc.), as well as engineered wood products.
As shown in FIG. 19, the factory 20 comprises a number of automated industrial stages integrated together under automation and control of controller 28, namely: a high-speed multi-stage lumber piece conveyor-chain mechanism 22 having 6 primary stages in the illustrative embodiment shown in FIGS. 19 and 19A; a kiln-drying stage 23 receiving short pieces of lumber 21 from a supply warehouse maintained in or around the factory; a finger-jointing lumber processing stage 24, for processing short-length pieces of kiln-dried lumber and automatically fabricating extended-length finger-jointed pieces of lumber 29, as output from this stage; a lumber planing and dimensioning stage 25 for planing and dimensioning elongated pieces of finger-jointed lumber into lumber pieces having lengths and dimensions for the product application at hand (e.g. studs); an in-line high-speed continuous CFIC liquid dip-infusion stage 26, as further detailed in FIG. 19A; and an automated stacking, packaging, wrapping and banding/strapping stage 27, from which bundles of packaged, wrapped and strapped Class-A fire-protected lumber product are produced in a high-speed automated manner.
During this last stage of the production process, each piece of Class-A fire-protected lumber is carbon-quantized using the carbon-quantization engine 500 over the network 100, and labeled or marked with the estimated quantity of fire-protected carbon units (FPCUs) in mass units (e.g. kg or tons) and recorded in the network database. This carbon quantization process may involve making a mass measurement of a sample piece of CFIC liquid dipped lumber, and also an electronically-measured moisture content measurement, and based on the dimensions and species of wood involved, the carbon quantization engine 500 takes this carbon quantization request and computes FPCU figure to this requests, records and registers the fire-protected lumber piece(s) or bundle, depending on how packaging is achieved, and the Class-A fire-protected carbon-quantized lumber piece (or bundle thereof) is labeled with the FPCU amount, by printing, stamping, laser etching or other marking means.
In general, the kiln-drying stage 23 can be implemented in different ways. One way is providing a drying room with heaters that can be driven by electricity, natural or propane gas, and/or other combustible fuels which release heat energy required to dry short-length lumber pieces prior to the finger-joint wood processing stage. Batches of wood to be treated are loaded into the drying room and treated with heat energy over time to reduce the moisture content of the wood to a predetermined level (e.g. 19% moisture). In alternative embodiments, the kiln-drying stage 23 might be installed an elongated tunnel on the front end of the production line, having input and output ports, with one stage of the conveyor-chain mechanism 22 passing through the heating chamber, from its input port to output port, allowing short-length lumber to be kiln-dried as it passes through the chamber along its conveyor mechanism, in a speed-controlled and temperature-controlled manner. Other methods and apparatus can be used to realize this stage along the lumber production line, provided that the desired degree of moisture within the wood is removed at this stage of the process.
As illustrated in FIG. 19, the finger-jointing lumber processing stage 24 can be configured as generally disclosed in US Patent Application Publication Nos. US20070220825A1 and US20170138049A1, incorporated herein by reference. In general, this stage involves robotic wood-working machinery, automation and programmable controls, well known in the finger-jointing wood art, and transforms multiple smaller-pieces of kiln-dried lumber into an extended-length piece of finger-jointed lumber, which is then planed and dimensioned during the next planning/dimensioning stage of the production line. An example of commercial equipment that may be adapted for the finger-jointing processing stage 24 of the present invention may be the CRP 2500, CRP 2750 or CRP 3000 Finger Jointing System from Conception R.P., Inc., Quebec, Canada http://www.conceptionrp.com/finger-jointing-systems.
As illustrated in FIG. 19, the lumber planing and dimensioning stage 25 includes wood planing equipment, such industrial band or rotary saws designed to cut and dimension finger-jointed lumber pieces produced from the finger-jointing lumber processing stage 24, into lumber boards of a specified dimension and thickness, in an highly programmed and automated manner.
As shown in FIG. 19A, the dip-infusion stage 26 of the factory system 20 comprises a number of components integrated together on the production line with suitable automation and controls, namely: a multi-stage chain-driven conveyor subsystem 22, supporting several parallel sets of chain-driven transport rails 22A1, 22A2 and 22A3, as shown, extending from the planing and dimensioning stage 25 towards the dipping tank 26B, and then running inside and along the bottom of the dipping tank 26B, and then running out thereof towards the stacking, packing, wrapping and banding/strapping stage 27, as shown, and having the capacity of transporting extend-length finger-jointed lumber pieces (i.e. boards) having a length as long as 30 or so feet; a dipping reservoir 26B having a width dimension to accommodate the width of the chain-driven conveyor rails 22A1, 22A2 and 22A3 mounted and running outside of and also within the dipping tank 26B, as shown, to transport up planed and dimensioned finger-jointed lumber pieces 29A supported upon the chain-driven rails 22A1, 22A2 and 22A3, while the boards are fully immersed and submerged at least 6 inches deep in CFIC liquid 26H contained in the dipping tank 26B, while moving at high speed, such as 300 feet/minute through the dipping tank 26B during the CFIC dip-infusion process of the present invention; electrically-powered driven motors 261 for driving the chain-driven conveyors 22A1, 22A2 and 22A3 under computer control to transport finger-jointed pieces of lumber from stage to stage along the lumber production line; a level sensor 26F for sensing the level of CFIC liquid 26B in the dipping tank at any moment in time during production line operation; a reservoir tank 26C for containing a large volume or supply of CFIC liquid solution 26K; a computer controller 26G for controlling the conveyor subsystem 22, and an electric pump 26D for pumping CFIC liquid into the dipping tank 26B to maintain a constant supply level during system operation in response to the liquid level measured by the level sensor 26F.
The high-speed CFIC liquid dip-infusion subsystem 26 shown in FIG. 19A may also include additional apparatus including, for example, liquid heaters, circulation pumps and controls for (i) maintaining the temperature of CFIC liquid solution in the dipping tank 26B, and (ii) controlling the circulation of CFIC liquid around submerged pieces of finger-jointed lumber 29A being transported through the dipping tank 26B in a submerged manner during a CFIC infusion process. Controlling such dip-infusion parameters may be used to control the amount and degree of absorption of CFIC liquid within the surface fibers of the finger-jointed lumber 29A as it is rapidly transported through the dipping tank 26B between the lumber planing and dimensioning stage 25 and the lumber stacking, packaging, wrapping and banding/strapping stage 27 of the lumber production line. Notably, the dip infusion process of the present invention allows for the rapid formation a surface infusion, or surface barrier, in and on the surface of each piece of dipped lumber, and in the presence of the surfactant in the CFIC liquid in the dipping tank, shallow impregnation of CFIC liquid 26H to occur into the surface fibers of each piece of lumber 29A near atmospheric pressure (i.e. below 6 inches of liquid CFIC in the dipping tank) during the dip-coated process according to the principles of the present invention. It is understood that drip pans may also be provided beyond the dipping tank 26B, installed beneath the chain-driven conveyor subsystem arranged between the dripping tank 26B and the stacking, packaging, wrapping and banding/strapping stage 27, to recover excess CFIC liquid dripping from the dip-coated lumber pieces 29A and returning this recovered CFIC liquid to the dipping tank 26B after appropriate filtering of the CFIC liquid if and as necessary.
As illustrated in FIG. 19, the stacking, packaging, wrapping and banding stage 27 includes equipment designed to automatically receive CFIC-coated finger-jointed lumber pieces 29A while still dripping and wet from CFIC liquid 26H, and wet stacking a predetermined number of lumber pieces into a package, and then wrapping the package of lumber with a sheet of wrapping material (e.g. TVEK or like material) that covers the top portion and at least half way down each side of the lumber package, and then banding or strapping the wrapped package with fiberglass or steel banding, well known in the art. The wrapping will typically be preprinted with trademarks and logos of the lumber manufacturer's brand. Finally, the ends of the lumber pieces in the strapped, wrapped lumber package are painted with a fire-protective paint also containing CFIC liquid (e.g. Hartindo AF21 Total Fire Inhibitor) in amounts to be effective in Class-A fire suppression.
FIGS. 20A and 20B describe the high level steps carried out when practicing the method of producing bundles of Class-A fire-protected finger-jointed lumber 29 for use in fire-protected building construction.
As indicated at Block A in FIG. 20A, in an automated lumber factory, a high-speed Class-A fire-protected lumber production line is installed and operated, with a reservoir tank 26C containing a large supply of clean fire inhibiting chemical (CFIC) liquid 26K (e.g. Hartindo AF21 Total Fire Inhibitor) that is supplied to the automated CFIC liquid dip-infusion stage 26 of the lumber factory 20, installed between (i) the lumber planing/dimensioning stage 25, and (ii) an automated stacking, packaging, wrapping and banding stage 27 in the lumber factory 20.
As indicated at Block B in FIG. 20A, a supply of untreated short-length lumber is loaded onto the high-speed conveyor-chain transport mechanism 22 and auto-feeder installed along and between the stages of the lumber production line.
As indicated at Block C in FIG. 20A, the untreated short-length lumber is loaded into the controlled-drying stage 23 of the fire-protected lumber production line so to produce suitably dried short-pieces of lumber for supply to the finger-jointing processing stage 24. This stage can be performed by loading batches of short length lumber into the drying room or oven, whose temperature and humidity are strictly controlled using electric heaters and other equipment under computer control. Alternatively, short-length lumber pieces can be controllably dried by moving batches of short-length lumber through a tunnel-like drying room or chamber, through which chain-driven conveyor mechanism 22 passes, like other stages along the lumber production line, while the temperature and humidity of the environment is controlled using electric-driven or gas-combusting heaters under computer control in a manner well known in the art.
As indicated at Block D in FIG. 20A, the controllably-dried short-length lumber is continuously supplied into the finger-jointing lumber processing stage 24, for producing pieces of extended-length finger-jointed lumber in a highly automated manner.
As indicated at Block E in FIG. 20B, produced pieces of extended-length finger-jointed lumber are automatically transported to the planing/dimensioning stage 25 so that the finger-jointed lumber can be planed/dimensioned into pieces of dimensioned finger-jointed lumber 29A, and outputted onto the multi-stage conveyor-chain transport mechanism 22.
As indicated at Block F in FIG. 20B, the dimensioned finger-jointed lumber pieces 29A are continuously transported and submerged through an automated dipping tank 26B for sufficient infusion of CFIC liquid (e.g. Hartindo AF21 liquid) into the lumber while being transported on the conveyor-chain transport mechanism 22.
As indicated at Block G in FIG. 20B, the wet dip-coated pieces of dimensioned finger-jointed lumber are continuously removed from the dipping tank 26B, and automatically wet-stacking, packing, wrapping and banding the wet dip-coated pieces into a packaged bundle of Class-A fire-protected finger-jointed lumber.
As indicated at Block H in FIG. 20B, the packaged bundle of Class-A fire-protected finger-jointed lumber is removed from the stacking, packaging, wrapping and banding stage 27 and stored in a storage location in the factory 20. The strapping the bundle material used may be made of high-strength fiberglass plastic or metal banding material.
As indicated at Block I in FIG. 20B, the ends of each packaged bundle of fire-protected dimensioned finger-jointed lumber 29, produced from the production line, are painted using a Class-A fire-protected paint containing clean fire-inhibited chemicals (CFIC) (e.g. 25% Hartindo AF21 liquid, 75% liquid polymer binder, and black liquid pigment) and applying trademarks and logos to the wrapped package of Class-A fire-protected finger-jointed lumber.
In the illustrative embodiment, Hartindo AF21 Total Fire Inhibitor liquid is used as the CFIC liquid 26H that is deposited as a CFIC surface infusion during the dip-infusion of wood/lumber products on the production line of the present invention described above. The surfactants in Hartindo AF21 liquid formulation break the surface tension and allow its chemical molecules to impregnate ever so slightly the surface of the treated wood. This way, in the presence of a flame, the chemical molecules in the CFIC-coating on the surface of the fire-protected lumber, interferes with the free radicals (H+, OH−, O−) produced during the combustion phase of a fire, and breaks the fire's chemical reaction and extinguishes its flame. This is a primary fire suppression mechanism implemented by the CFIC-coatings deposited on wood surfaces in accordance with the various principles of invention disclosed and taught herein.
The table in FIG. 21 illustrates the flame spread and smoke development indices of fire-protected carbon-quantized lumber 29 produced using the method of the illustrative embodiment, using Hartindo AF21 as a CFIC liquid dip coating material, described in FIGS. 20A and 20B. As shown in the table, the flame spread index for Spruce Pine Fir (SPF) was measured to be 15, whereas the smoke development index measured to be 95. The flame-spread index for Douglas Fir was measured to be 0, whereas the smoke development index measured to be 40.
Specification of the Method of and Apparatus for Producing Class-A Fire-Protected Cross-Laminated Timber (CLT) Panels in Accordance with the Principles of the Present Invention
FIG. 22 shows a bundle of fire-protected carbon-quantized cross-laminated timber (CLT) products (e.g. panels 42) produced using the method and apparatus of the present invention. The Class-A fire-protected cross-laminated timber (CLT) of the present invention 42 bears a surface infusion of clean fire inhibiting chemical (CFIC) liquid (e.g. Hartindo AF21 Total Fire Inhibitor). This CFIC infusion prevents flames from spreading by breaking the free radical chemical reaction within the combustion phase of fire, and confining the fire to the ignition source which can be readily extinguished, or go out by itself. When practicing the present invention, it is important that other fungicides, biocides, wood preservatives, and/or mildew agents are not added to the CFIC solution 39H (i.e. Hartindo AF21) in the CFIC dip infusion tank 32B because it has been discovered that such agents will chemically interfere with and adversely effect the fire-inhibiting properties and characteristics of the Hartindo AF21 fire-inhibiting chemicals, proven by E84 flame spread test results.
FIG. 23 shows an automated factory system 30 for producing Class-A fire-protected cross-laminated timber (CLT) panels, beams, and other products 42 in a high volume manner. As shown in FIG. 23, the factory 30 comprises a number of automated stages integrated together under automation and control, namely: a multi-stage conveyor-chain mechanism 32 having numerous primary stages in the illustrative embodiment shown in FIGS. 23 and 23A; a controlled-drying stage 33 receiving short pieces of lumber from a supply warehouse maintained in or around the factory and drying them in a controlled manner well known in the art; a finger-jointing stage 34, for processing short-length pieces of dried timber (i.e. lumber) and automatically fabricating extended-length finger-jointed pieces of timber, as output from this stage; a lamination planing stage 35 for planing finger-jointed pieces of timber to produce finger-jointed timber laminations; an automated adhesive stage 36 for applying adhesive to the finger-jointed timer laminations; a pressing and curing stage 37 where the finger-jointed laminations with adhesive are stacked in a cross-directional manner and then placed in pressing machine where the adhesive is cured under pressure to produce a cross-laminated timber (CLT) panel, beam or other product; cross-cutting and rip-sawing stage 38 for cutting and ripping cross-laminated timber (CLT) panels into CLT products 42A; a chain-driven conveyor 32 for conveying the CLT product 42A along the next few stages of the production line; an in-line CFIC liquid dip-infusion stage 39, as further detailed in FIG. 23A, supporting an elongated dipping tank 39B through which the chain-driven conveyor 32 transports CLT product into the dipping tank 39H and along its length while submerged under CFIC liquid (e.g. Hartindo AF21 Total Fire Inhibitor) 39H during dip-infusion operations, to form a CFIC infusion in and through the surfaces of the CLT product, and removing the CFIC-infused CLT product from the dipping tank and transport it to the next stage along the production line; a packaging and wrapping/labeling stage 40 for packaging and wrapping/labeling CLT product 42A either after it has dried, or while the CFIC-coated CLT product is still wet and allowed to dry in its wrapping.
During this last stage of the production process, each piece of Class-A fire-protected CLT is carbon-quantized using the carbon-quantization engine 500 over the network 100, and labeled or marked with the estimated quantity of fire-protected carbon units (FPCUs) in mass units (e.g. kg or tons) and recorded in the network database. This carbon quantization process may involve making a mass measurement of a sample piece of CFIC-dipped CLT, and also an electronically-measured moisture content measurement, and based on the dimensions and species of wood involved, the carbon quantization engine 500 takes this carbon quantization request and computes FPCU figure to this requests, records and registers the fire-protected carbon-quantized lumber piece(s) or bundle thereof, depending on how packaging is achieved, and the fire-protected carbon-quantized lumber piece (or bundle thereof) is labeled with the FPCU amount, by printing, stamping, laser etching or other marking means.
In general, the controlled-drying stage 33 will include drying room with heaters that can be driven by electricity, natural or propane gas, or other combustible fuels which produce heat energy required to dry short-length lumber prior to the finger-joint wood processing stage. Some alternative embodiments, the controlled-drying stage 33 might be installed on the front end of the production line as shown in FIG. 23, and having input and output ports, with one stage of the conveyor-chain mechanism 32 passing through the heating chamber, from its input port to output port, allowing short-length lumber to be kiln-dried as it passes through the chamber along its conveyor mechanism. Other methods and apparatus can be used to realize this stage of the lumber production line of the present invention, provided that the desired degree of moisture within the wood is removed with heat or radiant energy at this stage of the process.
As illustrated in FIG. 23, the finger-jointing lumber processing stage 34 can be configured as generally disclosed in US Patent Application Publication Nos. US20070220825A1 and US20170138049A1, incorporated herein by reference. In general, this stage involves robotic wood-working machinery, automation and programmable controls, well known in the finger-jointing wood art, and transforms multiple smaller-pieces of kiln-dried lumber into an extended-length piece of finger-jointed lumber, which is then planed and dimensioned during the next planning/dimensioning stage of the production line. An example of commercial equipment that may be adapted for the finger-jointing processing stage 34 of the present invention may be the CRP 2500, CRP 2750 or CRP 3000 Finger Jointing System from Conception R.P., Inc., Quebec, Canada http://www.conceptionrp.com/finger-jointing-systems.
As illustrated in FIG. 23, the laminating planing stage 35 includes wood lamination planing equipment, such industrial band or rotary saws designed to cut, plane and dimension finger-jointed lumber pieces produced from the finger-jointing stage 34, into finger-jointed timber laminations of a specified dimension and thickness.
As illustrated in FIG. 23, the lamination planing stage 35 can be realized using a band or radial saw as may be required to produce finger-jointed laminations.
As illustrated in FIG. 23, the adhesive application stage 36 can be realized using automated adhesive applicators well known in the art to apply a predetermined controlled amount of adhesive to each finger-jointed timber lamination during the automated finger-jointing process.
As illustrated in FIG. 23, the pressing and curing stage 37 can be realized using an automated pressing and curing machine well known in the art to apply a predetermined controlled amount of pressure to the timber laminations after they have been cross-configured, and placed into the machine for pressing and subsequent curing operations.

As shown in FIG. 23A, the in-line high-speed continuous CFIC liquid dip-infusion stage 39 of the production line comprises a number of components integrated together, with suitable automation and controls, namely: a multi-stage lumber board chain-driven conveyor subsystem 32, supporting several parallel sets of chain-driven transport rails 32A1, 32A2 and 32A3, as shown, extending from the pressing and curing stage 39 towards a dipping tank 39B, and then running inside and along the bottom of the dipping tank 39B, and then running out thereof, towards the packing and wrapping stage 40, as shown, and having the capacity of transporting CLT panels and boards having a length up to 30 or so feet.
In the illustrative embodiment, the dipping tank 39B has a width dimension of 32 or so feet to accommodate the width of the CLT product being transported on chain-driven conveyor rails 32A1, 32A2 and 32A3 mounted and running outside of and also within the dipping tank 39B, as shown. As shown, the CLT products 42A are supported upon the chain driven rails 32A1, 32A2 and 32A3 while the CLT products are transported through the dipping tank 39B while fully immersed and submerged at least 6 inches deep in CFIC liquid 39H contained in the dipping tank 39B, moving lumber in and out of the dipping tank 39B in just a few seconds during the CFIC dip-infusion process of the present invention. Electrically powered driven motors 391 are provided for the purpose of driving the chain-driven conveyors 32A1, 32A2 and 32A3 under computer control to transport CLT products 39E from stage to stage along the production line. A level sensor 39F is used for real-time sensing and control of the liquid level of CFIC liquid 39H in the dipping tank 39B at any moment in time during production line operation. A reservoir tank 39C is provided for containing a large volume or supply of made up CFIC liquid solution (e.g. Hartindo AF21 Total Fire Inhibitor). Also, a computer controller 39G is used for controlling the conveyor subsystem 32, and an electric pump 39D for pumping CFIC liquid into the dipping tank 39B to maintain a constant supply level during system operation in response to the liquid level measured by the level sensor 39F and supplied to the control computer 39G.
The high-speed dip-infusion subsystem 39 may also include additional apparatus including, for example, liquid heaters, circulation pumps and controls for (i) maintaining the temperature of CFIC liquid solution in the dipping tank 39B, and (ii) controlling the circulation of CFIC liquid around submerged CLT product 39E being transported through the dipping tank in a submerged manner during a CFIC infusion process. Controlling such dip infusion parameters may be used to control the amount and degree of absorption of CFIC liquid within the surface fibers of the CLT product, as it is rapidly transported through the dipping tank 39B. Notably, the dip infusion process allows for the rapid formation a surface infusion, or surface barrier, in and through the surface of each piece of dipped CLT product 39E, and in the presence of a surfactant in the CFIC liquid in the dipping tank 39B, shallow impregnation of CFIC liquid 39H (e.g. Hartindo AF21) can occur into the surface fibers of each CLT piece 42A near atmospheric pressure (i.e. below 6 inches of liquid CFIC in the dipping tank). It is understood that drip pans may also be provided beyond the dipping tank 39B, installed beneath the chain-driven conveyor subsystem 32 arranged between the dripping tank 39B and the packaging and wrapping stage 40, so as to recover excess CFIC liquid dripping from the dip-coated lumber pieces and returning this recovered CFIC liquid to the dipping tank 39B after appropriate filtering of the CFIC liquid if and as necessary.
As illustrated in FIG. 23, the packaging and wrapping stage 40 includes equipment designed to receive CFIC-coated CLT product while still dripping and wet from CFIC liquid, and wrapping the CLT product 42A with a sheet of wrapping material (e.g. TVEK or like material) that covers the top portion and at least half way down each side of the CLT product, and then banding or strapping the wrapped package 42 with fiberglass or steel banding, well known in the art. The wrapping will typically be preprinted with trademarks and logos of the lumber manufacturer's brand. Finally, the ends of the lumber pieces in the strapped, wrapped lumber package 42 are painted with a fire-protective paint also containing CFIC liquid material, in amounts to be effective in fire suppression.
FIGS. 24A and 24B describe the high level steps carried out when practicing the method of producing bundles of Class-A fire-protected cross-laminated timber (CLT) 42 for use in fire-protected building construction.
As indicated at Block A in FIG. 24A, in an automated lumber factory, a high-speed Class-A fire-protected lumber production line is installed and operated, with a reservoir tank 39B containing a large supply of clean fire inhibiting chemical (CFIC) liquid 39H that is continuously supplied to the automated high-speed CFIC liquid dip-infusion stage 39 of the lumber factory, installed between (i) a cross-cutting and rip-sawing stage 38, and (ii) an automated stacking, packaging, wrapping and banding/strapping stage 40 installed at the end of the production line in the factory.
As indicated at Block B in FIG. 24A, a supply of untreated short-length lumber is loaded onto the conveyor-chain transport mechanism 32 installed along and between the stages of the production line.
As indicated at Block C in FIG. 24A, the untreated short-length lumber is loaded into the controlled-drying stage of the production line so to produce suitably dried short-length lumber for supply to the finger-jointing processing stage 34. This stage can be performed by loading batches of short length lumber into the drying room or oven, whose temperature and humidity are strictly controlled using electric heaters and other equipment under computer control. Alternatively, short-length lumber pieces can be controllably dried by moving batches of short-length lumber through a tunnel-like drying room or chamber, through which chain-driven conveyor mechanism 32 passes, like other stages along the lumber production line of the present invention, while the temperature and humidity of the environment is controlled using electric-driven or gas-combusting space heaters under computer control in a manner well known in the art.
As indicated at Block D in FIG. 24A, the controllably-dried short-length lumber is continuously supplied into the finger-jointing stage 34, for producing pieces of extended-length finger-jointed timber (lumber) in a highly automated manner.
As indicated at Block E in FIG. 24B, pieces of extended length finger-jointed timber are planed and dimensioned into pieces of finger-jointed timber laminations, and outputting the same onto the conveyor-chain transport mechanism 32.
As indicated at Block F in FIG. 24B, adhesive material is applied to the finger-jointed timber laminations produced during Block E.
As indicated at Block G in FIG. 24B, at the pressing & curing stage 37, pressing a plurality of finger-jointed timber laminations together with applied adhesive between the laminations, and then curing the adhesively joined laminations to produce a cross-laminated timber (CLT) pieces.
As indicated at Block H in FIG. 24B, cross-laminated timber (CLT) pieces are planed and finished at the cross-cutting and rip-sawing stage 38, and outputting finished CLT product to the CFIC liquid dip infusion stage 39.
As indicated at Block I in FIG. 24B, the finished CLT products are continuously transported and submerged through the dipping tank 39B of the dip stage 39 for sufficient coating or infusion of CFIC liquid (e.g. Hartindo AF21 Total Fire Inhibitor) 39H into the CLT products, while being transported on the conveyor-chain transport mechanism 32.
As indicated at Block I in FIG. 24B, continuously removing the wet dip-coated cross-laminated timber (CLT) pieces are continuously removed from the dipping tank 39B, and automatically stacked, packaged and wrapped/labeled while wet with CFIC liquid, and allowed to dry within the package wrapping.
In the illustrative embodiment, Hartindo AF21 Total Fire Inhibitor is used as the CFIC liquid solution 34H to form the CFIC surface infusion onto treated wood/lumber products produced on the production line of the factory described above. The clinging agent in the Hartindo AF21 CFIC liquid enables its chemical molecules to cling to the surface of the CFIC-coated wood, while its surfactants help to break the surface tension and allow chemical molecules to impregnate ever so slightly the surface of the treated wood. This way, in the presence of a flame, the chemical molecules in the CFIC-infusion through the surface of the fire-protected lumber, interferes with the free radicals (H+, OH−, O−) of the chemical reaction produced within the combustion phase of a fire, and breaks the fire's chemical reaction and extinguishes its flame. This is a primary fire suppression mechanism deployed or rather implemented by the CFIC-coatings deposited on wood surfaces in accordance with the various principles of invention, disclosed and taught herein.
The table in FIG. 25 illustrates the flame spread and smoke development indices of fire-protected lumber produced using the method of the illustrative embodiment described in FIGS. 20A and 20B. As shown in the table, the flame spread index for Spruce Pine Fir (SPF) was measured to be 15, whereas the smoke development index measured to be 95. The flame-spread index for Douglas fir was measured to be 0, whereas the smoke development index measured to be 40.
Specification of the Method of and Apparatus for Producing Class-A Fire-Protected Laminated Veneer Lumber (LVL) Products (i.e. Studs and Boards) in Accordance with the Principles of the Present Invention
In many ways, LVL (Laminated Veneer Lumber) beams, headers, columns and studs provide a better alternative than traditional solid sawn lumber pieces, as such engineered wood products (EWPs) are a stronger, stiffer, more consistent and more predictable building material. Also, when compared to similar sized sections, fire-protected LVL products can support heavier loads and allow greater spans than conventional lumber. Every LVL product is made from sheets of veneer. When these sheets are combined into a continuous billet or piece of LVL, the effects of flaws in individual sheets are negated because they are spread throughout the cross-section of the billet, rather than being concentrated in specific locations, such as is the case with sawn lumber. For example, a flaw in a single sheet of veneer laid up into a 15-ply mat or billet of LVL will effectively be 1/15. The challenge facing LVL producers is how to make the strongest possible LVL from their available raw material using smart grading techniques to sort their veneers. LVL is produced and used in a variety of different lengths, thicknesses and widths. In general, the LVL process is based on a combination of continuous lay-up and cycle-type hot pressing that is suitable for the production of LVL products in all lengths.
FIG. 26 shows a stack of Class-A fire-protected laminated veneer lumber (LVL) products (i.e. beams, headers, columns, studs and rim boards) 57A produced using the method and automated factory system 45 shown in FIGS. 27 and 27A. The Class-A fire-protected laminated veneer lumber (LVL) products 57A bear two coatings: (i) an under-layer surface-coating of Class-A fire-protection provided by a dip-infusion of CFIC fire-inhibiting chemical (e.g. Hartindo AF21 Total Fire Inhibitor) which is allowed to stack-dry (e.g. for 24 hours or so); and (ii) a top-layer moisture, fire and UV protective coating that is spray-coated over the CFIC dip-coated, using a spraying tunnel 55, to deposit a moisture, fire and UV protection coating over the Class-A fire-protection coating over the LVL product.
In the illustrative embodiment, the top protective coating is formulated as follows: 75% by volume of Dectan chemical by Hartindo Chemicatama Industri; 25% by volume of Hartindo AF21 Total Fire Inhibitor; and 1.0-0.75 [cups/gallon] ceramic microsphere dust mixed in as an additive, where 1 cup=8.0 US fluid ounces. This rugged top protective coating, which Applicant will trademark under Gator Skin™, protects the CFIC infusion (e.g. Hartindo AF21 fire inhibitor) from being washed out under outdoor weather conditions expected during building construction when roof, wall and floor sheeting is exposed to and impacted by the natural environment until the building is “dried in.”
FIG. 27 shows an automated factory system 45 for producing Class-A fire-protected laminated veneer lumber (LVL) products in a high volume manner in accordance with the principles of the present invention. As shown in FIG. 27, the factory 45 comprises a number of automated stages integrated together under automation and control, namely: a conveyor-chain mechanism 47 having numerous stages in the illustrative embodiment shown in FIGS. 27 and 27A, and a stage for delivering clipped veneer to the front of the LVL production line. The stage that delivers the continuous supply of clipped veneer is supported by five preceding stages, starting in the log yard, where veneer logs are delivered to the log yard for the LVL process. There, the logs, graded A and J and suitable for peeling, are debarked at a log debarking stage, and then bathed in a hot bath at the hot log bath stage, to increase the core temperature of the logs up to about 65 degrees Celsius. Such hot log bath equipment can be obtained from the Southern Cross Engineering Co. Then, at a lathe peeling stage, the wood lathe scans the log profile using multiple lasers, then centers the log for the most efficient recovery of material and peels the logs to a core diameter (e.g. 78 mm for the Raute Wood Lathe) to produce peeled veneers. Raute Corporation of Nastola, Finland supplies lathe peeling equipment for this stage. At the clipping stage, the peeled veneers are clipped to a wet width of approximately 1.4 meters and then stacked according to their moisture content. Equipment for supporting this stage is supplied by Babcock & Wilcox.
As shown in FIG. 27, the LVL production line comprises, beyond its veneer delivery stage, an arrangement of stages, namely: a veneer drying stage 47 for receiving veneers from the supply and drying them in a controlled manner using, for example, a Babcock BSH, 22 bar, steam heated, six deck, roller veneer drier, supporting three stages of drying to reach a target moisture content of between 8 and 10%; a chain-driven conveyor 47 for conveying the components and LVL products along subsequent stages of the production line; an automated veneer grading stage 48 for automatically structurally and visually grading veneers using a Babcock NovaScan 4000 camera for surface appearance, a Metriguard 2650 DFX for ultrasonic propagation time, and an Elliot Bay Cypress 2000 moisture detection system; a veneer scarfing stage 49 for scarfing veneer edges to a uniform thickness at the joints between veneers, during the subsequent laying-up stage and process; adhesive application stage 50 for curtain coating veneers with phenol formaldehyde, an exterior grade adhesive, using a Koch (1400 mm curtain coater, with adhesive resin supplied by Dynea NZ Ltd.; a lay-up stage (i.e. station) 51 for vacuum lifting veneers (core sheets, face sheets and make-up sheets) onto the processing line according to the press recipe, and stacking and skew aligning the veneers with adhesive coating until they are laid up into a veneer mat; a pre-pressing stage 52 for pressing the veneer mat together; a hot-pressing and curing stage 53 for continuous hot pressing (over an extending length (e.g. 40 meters) using a Dieffenbacher hot press with hot oil platens to complete cure of the adhesive resin applied to the pressed veneers, and produce an LVL mat having a length up to 18m long in size, a width of up to 1.2m, and a thickness between 12 and 120 mm; a cross-cutting and rip sawing stage 53 for cross-cutting and rip sawing the produced LVL mat into LVL products such as studs, beams, rim boards and other dimensioned LVL products; an optional sanding stage, employing orbital sanders; an inkjet print-marking and paint spraying system for marking each piece of LVL product (e.g. LVL stud, board etc.) an with a branded logo and grade for clear visual identification; a CFIC liquid dip-infusion stage 54, as shown in FIG. 27A, having a dipping tank 54B through which the chain-driven conveyor 47 transports LVL product into the dipping tank 54B and along its length while submerged under CFIC liquid 54H (e.g. Hartindo AFF21 Total Fire Inhibitor from Newstar Chemicals, of Malaysia, or Hartindo Chemicatama Industri) during dip-infusion operations, so as to form a CFIC infusion in and through the surfaces of the LVL product, and removing the CFIC-coated LVL product from the dipping tank, and wet-stacking the LVL product and setting aside to dry for 24 hours or so to produce Class-A fire-protective LVL product 54E; a spray tunnel 55 for spray-coating Class-A fire-protective LVL product 54E (feed with an auto-feeder) with a moisture, fire and UV protective coating while the LVL product is being passed through a spraying tunnel 55 in a high-speed manner, and then quick-dried in a drying tunnel 56 and then passed onto the final stage 57; a stacking, packaging and wrapping/labeling stage 57 using Dieffenbacher, Signode equipment, for packaging and wrapping/labeling the Class-A fire-protected LVL product in its wrapping, ready for forklift handling. Notably, a liquid dye can be added to the CFIC dip-infusion liquid 54H without adversely effecting its chemical properties.

Such systems comprise: presses & curing machines; automation and controllers. Such technologies and machines can be used to implement many of the stages described above in the LVL product production line of the present invention.
As shown in FIG. 27A, the dip-infusion stage 54 comprises a chain-driven conveyor subsystem 47, supporting several parallel sets of chain-driven transport rails 47A1, 47A2 and 47A3 as shown, extending from the pressing and curing stage 53 towards a dipping tank 54B, and then running inside and along the bottom of the dipping tank 54B, and then running out thereof towards the stacking, packing and wrapping stage 57, as shown, having the capacity of handling studs and boards having a length up to 18 feet (6m) or so, as the production application may require.
In the illustrative embodiment, the dipping tank 55B has a width dimension of up to 32 feet to accommodate the width of the LVL product 54E being transported on chain-driven conveyor rails 47A1, 47A2 and 47A3 mounted and running outside of and also within the dipping tank 54B, as shown, and allowing sufficient dwell time in the CFIC liquid 54H during the dip-infusion process. As shown, the LVL products 54E are supported upon the chain driven rails 47A1, 47A2 and 47A3 while the LVL products 54E are transported through the dipping tank 54B while fully immersed and submerged at least 6 inches deep in CFIC liquid 54H contained in the dipping tank 54B, moving at the linear rate of 300 feet/minute through the dipping tank 54B during the CFIC dip-infusion process of the present invention. Electrically-powered driven motors are provided for the purpose of driving the chain-driven conveyors 47A1, 47A2, and 47A3 under computer control to transport LVL products along the production line. A level sensor 54F is used for real-time sensing the level of CFIC liquid 54H in the dipping tank 54B during production line operation. A reservoir tank 54K is provided for containing a large volume or supply of made up CFIC liquid 54H. Also, a computer controller 54G is used for controlling the conveyor subsystem 47, and an electric pump 54D is provided for pumping CFIC liquid 54H into the dipping tank 54B to maintain a constant supply level during system operation in response to the liquid level measured by the level sensor 54F and controlled by the controller 54G.
The high-speed dip-infusion stage 54 may also include additional apparatus including, for example, liquid heaters, circulation pumps and controls for (i) maintaining the temperature of CFIC liquid solution 54H in the dipping tank 54B, and (ii) controlling the circulation of CFIC liquid around submerged LVL product 54E being transported through the dipping tank in a submerged manner during the CFIC dip-infusion process. Controlling such dip infusion parameters may be used to control the amount and degree of absorption of CFIC liquid within the surface fibers of the LVL product as it is rapidly transported through the dipping tank 54B between the cross-cutting and rip-sawing stage 53 and the lumber packaging and wrapping stage 57 of the production line.
Notably, the dip infusion process of the present invention allows for the rapid formation a surface infusion, or surface barrier, in and through the surface of each piece of dipped LVL product, or in the presence of a surfactant added to the CFIC liquid in the dipping tank 54B, shallow impregnation of CFIC liquid 54H to occur into the surface fibers of each LVL piece 57A near atmospheric pressure (i.e. below 6 inches of liquid CFIC in the dipping tank) during the dip-coated process. It is understood that drip pans may also be provided beyond the dipping tank 54B, installed beneath the chain-driven conveyor subsystem 47 arranged between the dripping tank 54B and the packaging and wrapping stage 57 so as to recover excess CFIC liquid dripping from the dip-coated lumber pieces and returning this recovered CFIC liquid to the dipping tank after appropriate filtering of the CFIC liquid if and as necessary.
As shown in FIG. 27B, the moisture, fire and UV protection is provided using the spray tunnel stage 55 deployed immediately after the CFIC-liquid dip-infusion stage 54. As shown, the spray tunnel stage 55 comprises: a storage tank 55A for storing a large supply of moisture/fire/UV-protective liquid chemical 55B; a spray tunnel 55C for supporting an array of spray nozzles 55D arranged about the conveyor rails 55E1, 55E2 and 55E3, operably connected to a liquid pump 55E connected to the storage tank 55A under controller 55F, to provide a 360 degrees of spray coverage in the tunnel 55C, for spray-coating dip-infused LVL products within a controlled plane of moisture/fire/UV-protection liquid sprayed to cover 100% of surfaces of such LVL products 54E as they are being transported through the spray tunnel 55 at high-speed; and a drying tunnel stage 56 installed after the spray tunnel stage 55, for quick drying of spray-coated Class-A fire-protected LVL products, as they move through the drying tunnel 56 towards the automated stacking, packaging and wrapping stage 57 under the control of the subsystem controller 58. In the preferred embodiment, the moisture/fire/UV protection liquid 55B sprayed in the spray tunnel 55 is formulated as follows: 25% by volume Hartindo AF21 liquid; 75% by volume Dectan Chemical from Hartindo Chemicatama Industri of Indonesia, or its distributed Newstar Chemicals of Malaysia; and 1.0-0.75 [cups/gallon] of Hy-Tech ceramic microsphere dust, as an additive.
As illustrated in FIG. 27, the automated stacking, packaging and wrapping stage 57 includes equipment designed to receive Class-A fire-protected LVL product 54E, automatically stack the fire-protected LVL product, package and wrap the product within a sheet of wrapping material (e.g. plastic, TVEK or other wrapping material) covering the top portion and at least half way down each side of the LVL product package 59, and then banding or strapping the wrapped package 59 with fiberglass or steel banding, well known in the art. The wrapping will typically be preprinted with trademarks and logos of the lumber manufacturer's brand. Finally, the ends of the lumber pieces in the strapped, wrapped lumber package 59 are painted with a Class-A fire-protective paint, also containing CFIC liquid material (e.g. 25% by volume Hartindo AF21) to be effective in achieving Class-A fire-protection.
During this last stage of the production process, each piece of Class-A fire-protected LVL is carbon-quantized using the carbon-quantization engine 500 over the network 100, and labeled or marked with the estimated quantity of fire-protected carbon units (FPCUs) in mass units (e.g. kg or tons) and recorded in the network database. This carbon quantization process may involve making a mass measurement of a sample piece of CFIC liquid dipped LVL, and also an electronically-measured moisture content measurement, and based on the dimensions and species of wood involved, the carbon quantization engine 500 takes this carbon quantization request and computes FPCU figure to this requests, records and registers the fire-protected LVL piece(s) or bundle, depending on how packaging is achieved, and the fire-protected carbon-quantized piece (or bundle of) lumber is labeled with the FPCU amount, by printing, stamping, laser etching or other marking means.
FIGS. 28A and 28B describe the high level steps carried out when practicing the method of producing bundles of Class-A fire-protected carbon-quantized laminated veneer lumber (LVL) product for use in fire-protected building construction.
As indicated at Block A in FIG. 28A, a high-speed fire-protected lumber production line is installed and operated in an automated lumber factory 45, provided with an automated high-speed dip-infusion stage 54 and spray-coating stage 55 installed between (i) the cross-cutting and rip-sawing stage 53 of the production line, and (ii) an automated stacking, packaging and wrapping stage 57 installed at the end of the production line in the lumber factory 45.
As indicated at Block B in FIG. 28A, a supply clipped veneers 46 is continuously loaded onto the conveyor/transport mechanism 47 installed along the LVL production line.
As indicated at Block C in FIG. 28A, the veneers are continuously provided to the controlled drying stage 47 of the production line so to produce suitably dried veneers for supply to the veneer grading stage 49 and subsequent stages.
As indicated at Block D in FIG. 28A, dried veneers are scarfed at the veneer scarfing stage 49 to prepare for the veneer laying-up stage 51 where the leading and trailing edges of each sheet of veneer are scarfed (i.e. lapped-jointed) in order to provide a flush joint when the veneer sheets are joined together at the laying-up stage of the LVL process.
As indicated at Block E in FIG. 28B, adhesive material is applied by curtain coating at the adhesive application stage 50, to the surfaces of scarfed veneers prior to the veneer laying-up stage.
As indicated at Block F in FIG. 28B, the veneers are vacuum lifted onto the processing line and stacked and skew aligned with adhesive coating until the veneers are laid up, at the veneer laying-up line 51, into a veneer mat of a predetermined number of veneer layers (i.e. ply).
As indicated at Block G in FIG. 28B, the veneer mat is pressed together at the pre-pressing stage 52 of the production line.
As indicated at Block H in FIG. 28B, the veneer mat is hot pressed in a hot-pressing/curing machine to produce an LVL mat at the hot-pressing and curing stage 53 of the production line.
As indicated at Block I in FIG. 28B, the produced LVL mat is cross-cut and rip-sawed into LVL products (such as studs, beams, rim boards and other dimensioned LVL products) 54E at the cross-cutting and rip sawing stage 53.
As indicated at Block J in FIG. 28B, each piece of LVL product (e.g. LVL studs, boards, etc.) 54E is marked with a branded logo and grade for clear visual identification at the inkjet print-marking and paint spraying stage installed after the cross-cutting and rip-sawing stage 53.
As indicated at Block K in FIG. 28B, the cross-cut/rip-sawed LVL product 54E is continuously transported and submerged through the dipping reservoir 54B at the CFIC-liquid dip-infusion stage 54 so as to apply CFIC liquid 54H to the surface of the dipped LVL product 54E at a coating coverage density of about 300 square feet per gallon of CFIC liquid 54H (i.e. Hartindo AF21). The dip-coated LVL product 54E is then wet-stacked in an automated manner using auto-stacking machinery, and then set aside and allowed to dry for a predetermined period of time (e.g. 24 hours) before the stack of dip-coated LVL wood is returned to the production line for continued processing. In the illustrative embodiment, Hartindo AAF21 total fire-inhibitor is used as the CFIC liquid solution 54H, for depositing the CFIC surface-coating onto treated LVL products produced on the production line described above. The surfactants contained in the CFIC liquid helps to break the surface tension and allow chemical molecules to impregnate ever so slightly the surface of the treated LVL products, and produce a Class-A fire-protective LVL product 54E.
As indicated at Block L in FIG. 28C, the Class-A fire-protective LVL products 54E are continuously feed through the spray tunnel stage 55 for spray coating a moisture/fire/UV-protective liquid coating 55B over the entire surface as each dip-coated Class-A fire-protected LVL product (e.g. stud) 54E is feed through the spray tunnel 55.
As indicated at Block M in FIG. 28C, the Class-A fire-protected LVL product is quick-dried while being passed through the drying tunnel 56 disposed immediately after the curtain-coating tunnel 55. This produces a Class-A fire-protective LVL product with a moisture/fire/UV protective coating as it exits the production line, improving the durability of the Class-A fire-protective LVL product when exposed to outdoor weather conditions during the construction phase.
As indicated at Block N in FIG. 28B, Class-A fire-protective LVL product 59 is automatically stacked, packaged and wrapped at the automated stacking, packaging and wrapping stage 57, with trademarked wrapping, logos and the like.
In the presence of a flame, the chemical molecules in the CFIC-infusion along the surface of the Class-A fire-protected LVL lumber 54E interferes with the free radicals (H+, OH−, O−) produced during the combustion phase of a fire, and breaks the fire's free-radical chemical reactions and extinguishes its flame. This is a primary fire suppression mechanism implemented by the CFIC-coatings deposited on wood surfaces in accordance with the principles of invention, disclosed and taught herein.
The table in FIG. 29 illustrates the flame spread and smoke development indices of Class-A fire-protected lumber produced using the method described in FIGS. 28A and 28B. As shown in the table, for Spruce Pine Fire (SPF), the flame-spread index was measured to be 15, whereas the smoke development index was measured to be 95, meeting the test criteria for Class-A fire-protection rating. For Douglas Fir, the flame-spread index was measured to be 0, whereas smoke development index was measured to be 40, also meeting the test criteria for Class-A fire-protection rating.
Specification of Method of Producing Clean Fire-Protected Oriented Strand Board (OSB) Sheathing Constructed in Accordance with the Principles of the Present Invention
FIGS. 30 and 31 show a piece of Class-A fire-protected carbon-quantized oriented strand board (OSB) sheathing 60 constructed in accordance with the principles of the present invention. This Class-A fire-protected OSB sheathing 69 is provided with a moisture, fire and UV protection coating 64 that supports weather during building construction when roof, wall and floor sheeting gets hammered by the natural environment until the building is “dried in.” The coating 64 also protects the CFIC (e.g. Hartindo AF21 fire inhibitor) dip-infusions 63A and 63B and paint coating 63C from getting washed out by the weather during the construction phase, as otherwise occurs with most conventional pressure-treated lumber products.
As shown, the Class-A fire-protective OSB sheathing 60 comprises: a core medium layer 61 made of wood pump, binder and/or adhesive materials; OSB sheathing layers 62A and 62B bonded to the core medium layer 61; a clean fire inhibiting chemical (CFIC) coating 63C painted onto the edge surfaces of the core medium layer 61, using a Class-A fire-protective paint containing a CFIC liquid; CFIC coatings 63A and 63B applied to the surface of OSB sheathing layers 62A and 62B respectively, by dipping the OSB sheathing 66 into a CFIC liquid 66H contained in a dipping tank 66B, and allowing shallow surface absorption or impregnation into the OSB sheathing layers 62A and 62B at atmospheric pressure; and a moisture/fire/UV protective coating 64 spray-coated over the CFIC coatings 63A, 63B and 63C applied to protect these underlying CFIC coatings from outdoor weather conditions such as rain, snow and UV radiation from Sunlight.
In the illustrative embodiment, Hartindo AAF21 Total Fire Inhibitor is used as the CFIC liquid 66H to form the CFIC surface coatings 63A, 63B and 63C over the surfaces of the OSB product (e.g. sheet) 66. The clinging agent in the CFIC liquid 66H enables its chemical molecules to cling to the surface of the CFIC-coated OSB product, while its surfactants help to break the surface tension and allow chemical molecules to impregnate ever so slightly the surface of the treated wood. The CFIC paint coating 63A can be formulated by adding Hartindo AF21, 25-30% by volume, to a water-base paint containing liquid polymer binder.
In the illustrative embodiment, the moisture/fire/UV protection liquid 68A comprises a formulation comprising: 75% by volume, DECTAN chemical liquid from Hartindo Chemicatama Industri of Jakarta, Indonesia, a complex vinyl acrylic copolymer and tannic acid; 25% by volume, AF21 anti-fire liquid chemical from Hartindo Chemicatama Industri; and ceramic microsphere dust, 1.0-0.75 [cups/gallon] (e.g. ThermaCels™ insulating ceramic microsphere dust by Hy-Tech Thermal Solutions, LLC, of Melbourne, FL).

As shown, the OSB products are supported upon the chain driven rails 65E1, 65E2 and 65E3 while the OSB products 66E are transported through the dipping tank 66B while fully immersed and submerged at least 6 inches deep in CFIC liquid 66H contained in the dipping tank 66B, moving at the linear rate of 300 feet/minute through the dipping tank 66B during the CFIC dip-infusion process of the present invention. Electrically powered driven motors are provided for the purpose of driving the chain-driven conveyors under computer control to transport OSB products 66E from stage to stage along the production line. A level sensor 66F is used for sensing the level of CFIC liquid 66H in the dipping tank at any moment in time during production line operation. A reservoir tank 66C is provided for containing a large volume or supply of CFIC liquid 66H. Also, a computer controller 66G is used for controlling the conveyor subsystem, and an electric pump 66D is provided for pumping CFIC liquid 66H into the dipping tank 66B to maintain a constant supply level during system operation in response to the liquid level measured by the level sensor 66F and controlled by the controller 66G.

Controlling such dip infusion parameters may be used to control the amount and degree of absorption of CFIC liquid within the surface fibers of the OSB product 66E as it is rapidly transported through the dipping tank 66B between the cross-cutting and rip-sawing stage 65I and the lumber packaging and wrapping stage 65K of the production line. Notably, the dip infusion process allows for the rapid formation a surface infusion, or surface barrier, in, through and about the surface of each piece of dipped OSB product, or in the presence of a surfactant added to the CFIC liquid in the dipping tank 66B, shallow infusion of CFIC liquid 66H to occur into the surface fibers of each OSB sheet 66E near atmospheric pressure (i.e. below 6 inches of liquid CFIC in the dipping tank) during the dip-infusion process. It is understood that drip pans may also be provided beyond the dipping tank 66B, installed beneath the chain-driven conveyor subsystem arranged between the dripping tank 66B and the packaging and wrapping stage 65K so as to recover excess CFIC liquid dripping from the dip-infused lumber pieces and returning this recovered CFIC liquid to the dipping tank after appropriate filtering of the CFIC liquid if and as necessary.
As shown in FIG. 33B, the moisture, fire and UV protection is provided using the spray tunnel stage 67 deployed immediately after the CFIC-liquid dip-infusion stage 66. As shown, the spray tunnel stage 67 comprises: a storage tank 67A for storing a large supply of moisture/fire/UV-protective liquid chemical 67B; a spray tunnel 67C for supporting an array of spray nozzles 67D arranged about the conveyor rails 67A1, 67A2 and 67A3, operably connected to a liquid pump 67E connected to the storage tank 67A under controller 67F, to provide a 360 degrees of spray coverage in the tunnel 67, for spray-coating dip-infusion OSB sheets 66E within a controlled plane of moisture/fire/UV-protection liquid 67B sprayed to cover 100% of surfaces of such OSB sheets 66E as they are being transported through the spray tunnel 67 at high-speed; and a drying tunnel stage 56 installed after the spray tunnel stage 67, for quick drying of spray-coated Class-A fire-protected OSB sheet 66E, as they move through the drying tunnel 68 towards the automated stacking, packaging and wrapping stage 65K, under the control of the subsystem controller 58. In the preferred embodiment, the moisture/fire/UV protection liquid 67B sprayed in the spray tunnel 67 is formulated as follows: 25% by volume Hartindo AF21 liquid; 75% by volume Dectan Chemical from Hartindo Chemicatama Industri, or its distributed Newstar Chemicals of Malaysia; and 0.75 [cups/gallon] of Hy-Tech ceramic microsphere dust, as an additive.
As illustrated in FIG. 33, the automated stacking, packaging and wrapping stage 65K includes equipment designed to receive Class-A fire-protected OSB sheets 66E, automatically stacking the fire-protected OSB sheets, packaging and wrapping the sheets with wrapping material (e.g. plastic, TVEK or other wrapping material) that covers the top portion and at least half way down each side of the stacked OSB sheets, and then banding or strapping the wrapped package with fiberglass or steel banding, well known in the art.

Provided with this innovative two-coating system of UV/moisture/fire-protection, in the presence of a flame, the chemical molecules in both the moisture/fire/UV-protective coating 64 and CFIC-coatings 63A, 63B capture the free radicals (H+, OH−, O) produced during a fire, and break the fire's chemical reaction and extinguish its flame. This is a primary fire suppression mechanism deployed or rather implemented by the CFIC-coatings deposited on wood surfaces in accordance with the various principles of invention, disclosed and taught herein.
As indicated at Block A in FIG. 32A, in an automated factory configured for automated production of Class-A fire-protected OSB sheeting, an edge painting stage 65J, an CFIC liquid dipping stage 67, a spray tunnel stage 67, and a drying tunnel stage 68 are installed between the finishing stage 65I and automated packaging and wrapping stage 65K along the lumber production line.

As indicated at Block F in FIG. 32B, the strands are coated with resin and wax at the blending 65F to enhance the finished panel's resistance to moisture and water absorption.
As indicated at Block G in FIG. 32B, cross-directional layers of strands are formed into strand-based mats at the mat forming stage 65G.
As indicated at Block H in FIG. 32B, the mats are heated and pressed at the pressing and curing stage 65H to consolidate the strands and cure the resins and form a rigid dense structural oriented strand board (OSB) panel.
As indicated at Block I in FIG. 32B, at the finishing stage 65I, the structural OSB panel is trimmed and cut to size, and groove joints machined and edge sealants applied for moisture resistance.
As indicated at Block J in FIG. 32B, Class-A fire-protective paint (containing CFIC liquid, 25% by volume, Hartindo AF21 liquid) is applied to the edges of the trimmed and cut OSB panels, at the edge painting stage 65J.
As indicated at Block K in FIG. 32B, OSB panels are transported and submerged through the dipping tank 66B of the dipping stage 66 for sufficient infusion of CFIC liquid 66H, while being transported on the conveyor-chain transport mechanism 65E.
As indicated at Block L in FIG. 32B, the wet dip-coated OSB panels are removed from the dipping tank 66B, and wet stacked and set aside for about 24 hours or so, to allow the wet CFIC liquid to infuse into all of the surfaces of the dipped OSB panels 66E to penetrate into the panels 69 as the infusion dries.
As indicated at Block M in FIG. 32C, a stack of air-dried dip-infused OSB panels 66E is loaded to the auto-feeder of the second stage of the production line, shown in FIG. 33B.
As indicated at Block N in FIG. 32C, the dip-coated OSB panels 66E are spray-coated with a moisture, fire and UV protection coating 64 that supports weather during building construction, to produce Class-A fire-protected OSB panels 69.
As indicated at Block O in FIG. 32C, spray-coated dipped OSB sheets 69 are transported through a drying tunnel at stage 68.
As indicated at Block P in FIG. 32C, dried spray-coated/dipped OSB panels 69 are stacked, packaged and wrapped into a bundle of Class-A fire-protected OSB panels at the stacking, packaging and wrapping stage 65K.
During this last stage of the production process, each Class-A fire-protected OSB panel is carbon-quantized using the carbon-quantization engine 500 over the network 100, and labeled or marked with the estimated quantity of fire-protected carbon units (FPCUs) in mass units (e.g. kg or tons) and recorded in the network database. This carbon quantization process may involve making a mass measurement of a sample piece of Class-A fire-protected OSB panel, and also an electronically-measured moisture content measurement, and based on the species of wood components and resins and binders involved, the carbon quantization engine 500 takes this carbon quantization request and computes FPCU figure to this requests, records and registers the fire-protected OSB panel or bundle, depending on how packaging is achieved, and the fire-protected carbon-quantized OSB panel is labeled with the FPCU amount, by printing, stamping, laser etching or other marking means.
As shown and described above, the lumber factory 65 is configured for producing Class-A fire-protected OSB sheathing 69 fabricated in accordance with the principles of the present invention.
FIG. 34 shows the flame-spread and smoke-reading (development) characteristics associated with the Class-A fire-protected OSB sheathing 69 shown in FIGS. 30 and 31 and manufactured according to the method of the illustrative embodiment described in FIGS. 32A and 32B, and using the factory production line shown in FIGS. 33, 33A and 33B.
Specification of Method of Making Fire-Protected Top Chord Bearing (Floor) Truss (TCBT) Structure Constructed in Accordance with the Principles of the Present Invention
FIG. 35 shows a Class-A fire-protected carbon-quantized top chord bearing (floor) truss (TCBT) structure 70 constructed in accordance with the present invention. As will be described in greater detail herein, the method of production involves (i) producing Class-A fire-protected lumber sections, and (ii) producing heat-resistant metal truss connector plates 10′ coated with Dectan-chemical (i.e. indicating a 50% reduction in E119 Testing which reduces charring in the wood behind plate), and (iii) using these heat-resistant metal truss connector plates 10′ to secure connect together the Class-A fire-protected pieces of lumber to form a Class-A fire-protected floor truss structure 70.
The Class-A fire-protected floor truss structure 70 performs better than conventional I-joists, does not require doubling as do conventional I-joists, does not require drilling on site top pass and install plumbing pipes and electrical wiring, as do I-joists, and does not require expensive LVL rim joists, while being easier to install in wood-framed buildings. The fire-protected floor truss structure 70 of the present invention provides an innovative solution to conventional wooden floor trusses using metal nail connector plates to connect together small lumber sections which ignite easily and burn quickly in a building fire. During a building fire, conventional metal nail connector plates 10, shown in FIGS. 8A and 8B, bend in the heat of a fire and release from its lumber section, causing the truss to loose all strength in a fire, as shown in FIG. 15. This places occupants at great risk trying to escape a burning wood-framed building, as well as firemen trying to extinguish a fire in a burning building before the fire reaches its critical stage.

BHD of Selangor Darul Ehsan, Malaysia, http://newstarchemicals.com/products.html. When so treated, combustible products will prevent flames from spreading, and confine fire to the ignition source which can be readily extinguished, or go out by itself. In the presence of a flame, the chemical molecules in both dry and wet coatings, formed with Hartindo AF31 liquid, interferes with the free radicals (H+, OH−, O) involved in the free-radical chemical reactions within the combustion phase of a fire, and breaks these free-radical chemical reactions and extinguishes the fire's flames.
In general, any commercially-grade airless liquid spraying system may be used and adapted to construct the GPS-tracked mobile system 101 for spraying Class-A fire-protective liquid coatings on wood-framed building construction sites, and practice the method and system of the present invention, with excellent results. Many different kinds of commercial spray coating systems may be used to practice the present invention, and each may employ an electric motor or air-compressor to drive its liquid pump. For purposes of illustration only, the following commercial spray systems are identified as follows: the Xtreme XL™ Electric Airless Spray System available from Graco, Inc. of Minneapolis, MN; and the Binks MX412 Air-Assisted/Compressor-Driven Airless Spray System from Carlisle Fluid Technologies, of Scottsdale, AZ.
Countless on-site locations will exist having various sizes and configurations requiring the on-job-site spray-based fire-protection method of the present invention. FIG. 51A illustrates a first job-site of multi-apartment wood-framed building under construction prepared and ready for clean fire inhibiting chemical spray coating treatment in accordance with the principles of the present invention. FIG. 51B illustrates a second job-site of multi-apartment wood-framed building under construction prepared and ready for clean fire inhibiting chemical spray coating treatment in accordance with the principles of the present invention.
The on-job-site spray method and system involves spraying a clean fire inhibiting chemical (CFIC) liquid on all new construction lumber and sheathing to prevent fire ignition and flame spread. The method also recommends spraying exterior walls or the exterior face of the roof, wall and floor sheathing with CFIC liquid. The method further recommends that factory-applied fire-protective lumber be used on exterior walls, and fire-protected sheathing be used on the exterior face of the roof, wall and floor sheathing, as it offers extra UV and moisture protection. As disclosed herein, there are many different options available to architects and builders to meet such requirements within the scope and spirit of the present invention disclosed herein.
In the illustrative embodiment, Hartindo AF31 Total Fire Inhibitor (from Hartindo Chemicatama Industri of Jakarta, Indonesia http://hartindo.co.id, or its distributor Newstar Chemicals of Malaysia) is used as the CFIC liquid 101C to spray-deposit the CFIC surface coating onto treated wood/lumber and sheathing products inside the wood-framed building under construction. A liquid dye of a preferred color from Sun Chemical Corporation http://www.sunchemical.com can be added to Hartindo AF31 liquid to help the spray technicians visually track where CFIC liquid has been sprayed on wood surfaces during the method of treatment. The clinging agent in this CFIC liquid formulation (i.e. Hartindo AF31 liquid) enables its chemical molecules to cling to the surface of the CFIC-coated wood so that it is quick to defend and break the combustion phase of fires (i.e. interfere with the free radicals driving combustion) during construction and before drywall and sprinklers can offer any defense against fire. However, a polymer liquid binder, available from many manufacturers (e.g. BASF, Polycarb, Inc.) can be added as additional cling agent to Hartindo AF31 liquid, in a proportion of 1-10% by volume to 99-90% Hartindo AF31 liquid, so as to improve the cling factor of the CFIC liquid when being sprayed in high humidity job-site environments. Alternatively, liquid DecTan Chemical from Hartindo Chemicatama Industri, which contains a mixture of vinyl acrylic copolymer and tannic acid, can be used a cling agent as well when mixed the same proportions, as well as an additional UV and moisture defense on exterior applications. These proportions can be adjusted as required to achieve the cling factor required in any given building environment where the spray coating method of the present invention is being practiced. This way, in the presence of a flame, the chemical molecules in the CFIC-coating on the surface of the fire-protected lumber, interfere with the chemical reactions involving the free radicals (H+, OH−, O−) produced during the combustion phase of a fire, and break the fire's chemical reaction and extinguish its flame. This is a primary fire suppression mechanism deployed or rather implemented by the CFIC-coatings deposited on wood surfaces in accordance with the various principles of invention, disclosed and taught herein.
Specification of Method of Producing Multi-Story Wood-Framed Buildings Having Class-A Fire-Protection and Improved Resistance Against Total Fire Destruction
FIGS. 52A and 52B, taken together, set forth a high-level for chart describing the steps carried out when practicing the method of producing multi-story wood-framed buildings having improved fire resistance rating and protection against total fire destruction. The method comprises a series of steps described below which effectively results in the coating of substantially all exposed interior wood surfaces of the raw untreated as well as fire-treated lumber and sheathing used during the construction phase of the wood-framed building, to protect and defend its wood, lumber and sheathing from ravage of fire and prevent total destruction by fire. The method recommends use of (i) the fire-protected OSB sheathing shown in FIGS. 30 through 32 and described herein for the exterior face of the roof, wall and floor sheathing, and (ii) the fire-protected lumber products shown in FIGS. 18-21, 22-25, and 26-29, and described herein for interior and exterior wall studs, trusses, sills, and other wood-frame related building structures.
The spray-coating fire-treatment process of the present invention may be carried out as follows. Spray-coating technicians (i) appear on the new construction job-site after each floor (i.e. wood-framed building section) has been constructed with wood framing and sheathing; (ii) spray liquid CFIC solution over substantially all of the exposed interior surfaces of the wood, lumber and sheathing used in the completed wood-framed building section; then (iii) certify that each such wood-framed building section has been properly spray-coat protected with CFIC liquid chemicals in accordance with the principles of the present invention, and (iv) use the carbon-quantization engine 500 to compute the fire-protected carbon units (FPCUs) for each completed and Class-fire-protected wood-framed building section, or mass timber building section, in a wood-framed or mass timber building under construction. Details of this method will be described in greater detail below in a step-by-step manner.
As indicated at Block A in FIG. 52A, the first step of the method involves fire-protection spray-coating technician to receives a request from a builder to spray a clean fire inhibiting chemical (CFIC) liquid coating over substantially all exposed interior surfaces of the untreated and/or treated wood lumber and sheathing used to construct a completed wood-framed section of a building under construction at a particular site location. This order could come in the form of a written work order, and email message, or other form of communication, with appropriate documentation.
As indicated at Block B in FIG. 52A, the second step of the method involves the fire-protection spray-coating technician (i) receiving building construction specifications from the builder, architect and/or building owner, (ii) analyzing same to determine the square footage of clean fire inhibiting chemical (CFIC) liquid coating to be spray applied to the interior surfaces of the wood-frame building, (iii) computing the quantity of clean fire inhibiting chemical material required to do the spray job satisfactorily, and (iv) generating a price quote for the spray job and sending the quote to the builder for review and approval.
As indicated at Block C in FIG. 52A, the third step of the method involves, after the builder accepts the price quote, the builder orders the clean fire-protection spray team to begin performing the on-site wood coating spray job in accordance with the building construction schedule.
As indicated at Block D in FIG. 52A, the fourth step of the method involves, after the builder completes each completed section of wood framing with wood sheathing installed, but before any wallboard has been installed, the spray technician (i) procures a supply of clean fire-protection chemicals (CFIC) liquid solution, (ii) fills the reservoir tank of an airless liquid spraying system with the supply of CFIC liquid, and (iii) then uses a spray gun to spray CFIC liquid in the reservoir tank, over all exposed interior wood surfaces of the completed section of the wood-framed building under construction. FIGS. 49 and 50 show an air-less liquid spraying system 101 for spraying CFIC liquid over all exposed interior surfaces of lumber and wood sheathing used in a completed section of the wood-framed building under construction, so as to form a Class-A fire-protective coating over such treated surfaces.
As indicated at Block A in FIG. 53, the first stage of this step involves procuring water-based CFIC liquid for on-job-site spray-treatment of raw untreated and treated lumber and sheathing used inside a wood-framed building. In the preferred embodiment, Hartindo AF31 from Hartindo Chemicatama Industri (and available from its distributor Newstar Chemical of Malaysia) is used as the CFIC liquid employed by the method of the present invention. Hartindo AF31 CFIC is an environmentally-friendly water-based, biodegradable and non-toxic solution that is non-ozone depleting and does not require cleanup procedures after usage. Hartindo AF31 CFIC is also effective for all classes of fires: involving solid, carbonaceous materials; flammable fuels, thinners, etc.; gas, electricity fires, and energy fires; and metal fire and oxidizing fires.
As indicated at Block B in FIG. 53, the second stage of this step involves filling the tank of the air-less liquid spraying system 101 with the procured supply of CFIC liquid.
As indicated at Block C in FIG. 53, the third stage of this step involves using the spray nozzle gun 103 of the air-less liquid spraying system 101 as shown in FIGS. 49 and 50, to a spray apply a uniform coating of liquid clean fire inhibiting chemical (CFIC) liquid over all of the interior surfaces of the completed section of wood-framed building being spray treated during the construction phase of the building, in accordance with the principles of the present invention. In the illustrative embodiment, the liquid CIFC (i.e. Hartindo AF31) is applied at a rate (i.e. coating coverage density) of about 590 square feet per gallon, although it is understood that this rate may vary from illustrative embodiment, to illustrative embodiment.
The CFIC liquid used in the present invention clings to the wood on which it is sprayed, and its molecules combine with the (H+, OH−, O−) free radicals in the presence of fire, during combustion, to eliminate this leg of the fire triangle so that fire cannot exist in the presence of such a CFIC based coating.
FIGS. 51A and 51B shows a few illustrative examples of building construction job site locations where the spray-based fire protective method of the present invention might be practiced with excellent results. It is understood that such examples are merely illustrative, and no way limiting with regard to the present invention.
As indicated at Block E in FIG. 52B, during the fifth step of the method, when the completed section of the building has been spray coated with clean fire inhibiting chemical (CFIC) liquid, the completed building section is certified and marked as certified for visual inspection and insurance documentation purposes, as well as fire-protected carbon unit (FPCU) quantization and labeling using the carbon quantization engine 500 over the network 100. Such marking can involving stamping a CFIC spray-coated sheath, or lumber board, with a seal or certificate using an indelible ink, with date, job ID #, sprayer #, and other information related to specific spray-coat fire-protection job that have been certified as a completed at that wood-framed building section. Preferably, the architectural plans for the building, as well as building schematics used on the job site, will have building section identification numbers or codes, which will be used on the certificate of completion stamped onto the spray-coated fire-protected sheathing and lumber on the job site.
As part of the certification process, an on-job-site spray project information sheet is maintained in an electronic database system, connected to a wireless portable data entry and record maintenance system. The on-job-site spray project information sheet would contain numerous basic information items, including, for example: Date; Customer Name; Weather Description and Temperature; Building Address; Customer Address: Customer Supervisor; Units of Part of the Building Sprayed; Sprayer Used; Spray Technician Supervisor; and Notes. Photographic and video recordings can also be made and stored in a database as part of the certification program, as will be described in greater detail below.
As indicated at Block F in FIG. 52B, during sixth step of the method, as each section of the wood-framed building is constructed according to the construction schedule, the spray coating team continues to spray coat the completed section, and certify and mark as certified each such completed spray coated section of the building under construction.
As indicated at Block G in FIG. 52B, during the seventh step of the method, when all sections of the building under construction have been completely spray coated with clean fire inhibiting chemical (CFIC) materials, suppressing fire ignition and suppression by capturing free radicals (H+, OH−, O−) during the combustion phase, and certified as such, the spray technicians remove the spray equipment from the building, and the builder proceeds to the next stages of construction and completes the building construction according to architectural and building plans and specifications.
As indicated at Block H in FIG. 52B, during the eighth step of the method, the spray technician then issues a certificate of completion with respect to the application of clean fire-protection chemicals to all exposed wood surfaces on the interior of the wood-framed building during its construction phase, thereby protecting the building from risk of total destruction by fire. Preferably, the certificate of completion should bear the seal and signature of a professional engineer (PE) and the building architect who have been overseeing and inspecting the building construction project.
As indicated at Block I in FIG. 52B, during the ninth step of the method, before applying gypsum board and/or other wall board covering over the fire-protected spray-coated wood-framed building section 105, digital photographs and/or videos are captured and collected to visually show certificates of completion stamped or otherwise posted on spray-coated fire-protected sheeting and/or lumber used in the wood framing of each completed building section. Such photographs and videos will provide valuable visual evidence and job-site completion documentation, required or desired by insurance companies and/or government building departments and/or safety agencies.
As indicated at Block J in FIG. 52B, during the tenth step of the method, uploading captured digital photographs and videos collected during Block I, to a centralized web-based information server (111, 113) maintained by the fire-protection spray coating technician company, or its agent, as a valued-added service provided for the benefit of the builder, property owner and insurance companies involved in the building construction project.
As indicated at Block K in FIG. 52B, during the eleventh step of the method, all photographic and video records collected during Block I, and uploaded to the centralized web-based information server (111, 113) at Block J are automatically archived indefinitely for best practice and legal compliance purposes.
FIG. 54 shows a schematic table representation illustrating the flame spread and smoke development indices obtained through testing of on-job-site Hartindo AF31 spray-treated lumber and sheathing produced using the method of the illustrative embodiment described in FIGS. 49 through 53, in accordance with ASTM E2768-1.
Advantages and Benefits of the On-Job-Site Method of Wood-Treatment and Fire-Protection by Way of Spray Coating of CFIC Liquid Over the Surface of Exposed Interior and Exterior Wood Used in Wood-Framed Buildings
The on-site spray coating method of the present invention described above involves the use of CFIC liquid having the property of clinging onto the surface of the wood to which it is applied during on-job-site spray-coating operations, and then inhibiting the ignition of a fire and its progression by interfering with the free-radicals (H+, OH−, O−) involved in the combustion phase of any fire. Hartindo AF31 liquid fire inhibitor meets these design requirements.
In general, CFIC liquids that may be used to practice the on-site fire-protection method of the present invention suppresses fire by breaking free radical (H+, OH−, O−) chemical reactions occurring within the combustion phase of fire, quickly and effectively suppressing fire in a most effective manner, while satisfying strict design requirements during the construction phase of a wood-framed building construction project. At the same time, the spray-based method of wood treatment and fire-protection will not degrade the strength of the wood materials (i.e. Modulus of Elasticity (MOE) and the Modulus of Rupture (MOR)) when treated with the CFIC-based liquid spray chemicals applied during the method of treatment.
The on-site wood lumber/sheathing spraying method of the present invention overcomes the many problems associated with pressure-treated fire retardant treated (FRT) lumber, namely: “acid hydrolysis” also known as “acid catalyzed dehydration” caused by FRT chemicals; significant losses in the Modulus of Elasticity (MOE), the Modulus of Rupture (MOR) and impact resistance of pressure-treated wood.

In the preferred embodiment, each mobile computing system 117 is configured for: (i) capturing digital photographs and video recordings of completed spray-treated wood-framed sections with barcoded/RFID-tagged certificates of inspection 300 posted in buildings under construction 118 (118A, 118B, 118C), as illustrated in FIGS. 51A and 51B, upon completion of the on-site fire-protection spray process at specific building sections; (ii) recording notes and averments by the spray technicians who applied the CFIC liquid spray and supervisors who supervised the same; and (iii) uploading such time-date-stamped digital audio-video (AV) recordings and 121 to the servers 111, 112, 113 in the data center 110, providing documented evidence of barcoded/RFID-tagged certificates of inspection (at inspection checkpoints) 300 stamped/printed or otherwise posted on the surfaces of sprayed wood surfaces, for each fire-protection spray-treatment project, so that insurance companies, builders, and other stakeholders (who are registered users of the system) can access and review such on-site spray completion certifications during and after the construction phase of a wood-framed building, for various purposes.
In general, each barcoded/RFID certificate of inspection 300 comprises a barcode symbol structure 300A, an RFID-tag (e.g. UHF class) 300B, a plastic substrate 300C on which the barcode symbol 300A and RFID-tag 300B are mounted, spray certifications and spray verifications 300D, and a spray project identification profile 300E. The plastic substrate 300C can be realized as a molded plastic plate, or flexible extruded sheet. The barcode symbol 300A and UHF RFID tag 300B may be integrated into a single structure, or realized separately, as the case may be. The barcode/RFID-tag structure 300A/300B can be mounted to the substrate 300C using an adhesive or other mounting means.
In general, various kinds of barcode symbol and RFID-tag technologies can be used to realize the barcoded/RFID-tagged certificates of inspection 300 posted in buildings under construction 118 (118A, 118B, 118C). Various RFID-labels and RFID-tags 300B, and barcode labels 300A are available from Zebra Technologies, Inc., Holtsville, NY. Also, Zebra Technologies provides hand-held mobile computers 117, wearable computers 117, vehicle-mounted computers 117, tablets and hand-held RFID readers (i.e. mobile computing devices 117), and barcode symbol, RFID-label and RFID-tag printers 117A, and RFID-tag readers (i.e. scanners) 117A shown in FIGS. 64 and 76, for use in practicing the principles of the present invention disclosed herein.

From the GPS signals it receives, each GPS transceiver is capable of computing in real-time the GPS location of its host system, in terms of longitude and latitude. In the case of the Empire State Building in NYC, NY, its GPS location is specified as: N40° 44.9064′, W073° 59.0735′; and in number only format, as: 40.748440, −73.984559, with the first number indicating latitude, and the second number representing longitude (the minus sign indicates “west”).
FIG. 56A shows the mobile client computing system 117 (117A, 117B, 117C) deployed on the system network 100 shown in FIG. 55, supporting the mobile application 120 installed on each mobile computing system 117. The purpose of the mobile application 120 is to provide the mobile computing system 117 with a convenient tool for tracking and managing projects involving on-site clean fire inhibiting chemical (CFIC) liquid spray treatment of wood-framed buildings during the construction phase, and the logistics associated therewith, to ensure the provision of Class-A fire-protection of all exposed interior wood surfaces in the wood-framed building. All stakeholders (e.g. building owners, architects, builders, property insurance underwriters, local fire departments and firemen, and others such as project coordinators, spray technicians, site superintendents, site spray managers and others who are involved in the logistics, management and application of CFIC liquid spray onto and over all exposed interior surfaces of the building) will benefit from the system network 100 and its deployed mobile application 120, and the services it supports across the enterprise.
Using the custom-designed mobile application 120, property/building owners, architects, builders, insurance companies and other stakeholders can (i) track the progress being made while a wood-framed building is being spray-treated with CFIC liquid during the construction project schedule, and (ii) review all collected pdf documents, digital images and audio-video recordings collected as visual evidence of “certificates of completion” by trained personnel, at predetermined inspection checkpoints in the wood-framed building, during the course of the construction project.
The purpose of such digital evidence, collected on-site at each inspection checkpoint and remotely stored in the network database 113A, is to verify and document proper application of CFIC liquid spray to each indexed inspection checkpoint designated at the commencement of the Project, and located throughout the interior of the wood-framed building to ensure that 100% of all exposed interior surfaces within the wood-framed building have been provided with Class-A fire-protection.
Preferably, each inspection checkpoint will be identified by Project ID # with a unique coding to identify the Building #, Floor #, Section #, and optionally Panel # at which the inspection checkpoint is located, and where certificates of completion (for the specified section) will be stamped, signed and AV-recorded, and actual wood samples sprayed with CFIC liquid at the time of the certified spray application are AV-recorded and collected and archived for verification and documentation purposes. The AV-recording of certifications made at each registered inspection checkpoint in the wood-framed building should help to ensure that Class-A fire-protected wood-samples will be available in the future in the event there might be a need to investigate the Class-A fire-protection spray treatment process.

Specification Of Network Database Supported On The System Network Of The Present Invention
FIG. 57A shows an exemplary schema 124 for the network database 113A supported by the system network 109 shown in FIG. 55. Each primary enterprise object is schematically represented as an object in the schema and represented in the data records created and maintained in the network database. As shown, the schema 124 includes objects such as, for example: Users of the system (e.g. property owners, builders, spray technicians, insurance companies, etc.); Real Property; Orders For On-Site Class-A Fire-Protection Liquid Spray Treatment; Clean Fire Inhibiting Chemical (CFIC) Liquid Supplies; Construction Project; and Mobile CFIC Liquid Spraying Systems. Each of these objects have further attributes specified by other sub-objects indicated in FIG. 57
Using Mobile Computing Devices Deployed on the System Network to Verify and Document CFIC Liquid Spray Certifications Made at Each Barcoded/RFID-Tagged Inspection Checkpoint Specified Throughout the Wood-Framed Building being Spray-Treated to Provide Class-A Fire Protection and Requesting Carbon-Quantization Using the Carbon-Quantization Engine
FIG. 57B shows a schematic map indicating the bar-coded/RFID-tagged inspection checkpoints assigned to specific locations throughout a wood-framed building, by a spray project administrator, prior to the commencement of a project requiring the spraying of all interior wood surfaces thereof with CFIC liquid so as to provide Class-A fire-protection thereto. In this example, the building has two floors, and each floor has several sections requiring spray-treatment with CFIC liquid, to provide Class-A fire-protection, in accordance with the principles of the present invention.
In general, this map will be created at the commencement of each project for a specified wood-framed building under construction, and its data structure will be stored in the network database 113A for the created project, to enable the organized capture of barcoded/RFID-tagged certifications, verifications and related documentation after spraying each completed wood-framed section.
Each section of the wood-framed building will be provided with at least one GPS-specified barcoded/RFID-tagged inspection checkpoint 300 (e.g. bearing certificates of spraying and inspection by spray technicians and site supervisors printed on a thin flexible plastic sheet, on which a barcode symbol/RFID-tag are mounted) indicated at 300 on the map. The map of FIG. 57B should clearly show the building/floor/section-specific locations of the barcoded/RFID-tagged inspection checkpoints 300, shown in FIGS. 63 and 64, on the floor plan of the wood-framed building, where the bar-coded/RFID-tagged inspection checkpoints 3000 will be mounted on spray-treated wood surfaces, at the completion of spray-treating each section of the wood-framed building, and subsequently signed by the spray technician and spray supervisor, and possibly the building site superintendent, and thereafter digitally photographed and video-recorded with the individuals involved in each such event being verified and documented using the system network of the present invention 100 and its deployed mobile applications 120.
At each barcoded/RFID-tagged inspection checkpoint 300, the spray technician and/or site supervisor uses his mobile computing device 117 to read the bar code symbol and/or RFID tag at the inspection checkpoint, to automatically (or semi-automatically) open the project storage location on the network database 113A, and then capture and record digital images and AV-recordings of signed spray certifications and verifications by the spray technicians and/or site supervisor, and upload them to the network database 113A using the mobile computing device 117 and mobile application 120, in the case where native mobile applications have been deployed. The mobile application 120 will also capture the GPS coordinates of the mobile computing device 117, and enter these coordinates into the project file/folder in the network database 113A, for verification purposes. The mobile application 120 can also capture the IP address of the user's mobile computing device (e.g. Apple iPhone) and record such address information as well. Preferably, at each barcoded inspection checkpoint 300, a set of four bar-coded Class-A fire-protect test boards 301, and a pair of bar-coded UV-protected storage sleeve 302A and 302B, each adapted to store two test boards 301 after CFIC liquid has been spray thereupon to impart Class-A fire protection. One set of sprayed test sample boards will be provided to the building owner, or its professional engineer, to be held in custody for evidentiary purposes. The other set will go to spray contracting firm, typically its laboratory, for post-spray testing purposes, and also to hold for custodial reasons. Digital images of these spray-treated test boards 301 should also be captured and uploaded to the network database 113A in the project folder under the specific inspection checkpoint at which the sprayed test samples where made, at a specific time and date, and GPS-location. Thereafter, these sprayed test boards 301 can be stored in their respective bar-coded storage sleeves 302A, 302B and provided to their respective parties. After such sprayed test samples have been made, and documented, it may desired for the spray contracting firm to send its sprayed test boards 301 to a scientific and engineering laboratory and conduct some tests to ensure that the highest possible scientific and engineering standards have been attained during the on-site spray treatment process, associated with each and every on-site wood-framed building fire-protection spray process. Laboratory technicians may also use the mobile application 120 and system network 100 to add any information they might have regarding the their testing of sprayed test boards 301 produced at each barcoded inspection checkpoint in the project.
Once all certifications and verifications have been made by the spray technician and his site supervisor, and digital photographic and AV-recording documentation (i.e. evidence) has been captured and uploaded to the network database 113A under the building-specific project, at a GPS-specified/barcoded inspection checkpoint 300, the spray technician will resume spraying other sections of the wood-framed building requiring spray treatment with CFIC liquid.
When using the system network of the present invention 100, each certification and verification made by the spray technician and site supervisor at the barcoded inspection checkpoint, and captured and recorded in the network database 113A using the user's mobile computing device 117 (e.g. Apple iPad), should include a legal declaration that a specific CFIC liquid formulation (e.g. Hartindo AF31 anti-fire liquid) has been applied to the sprayed wood surfaces of the completed section of this specific wood-framed building at a particular time and date, and in an active concentration sprayed onto the wood surfaces so as to provide the sprayed wood surfaces with Class-A fire-protected characteristics, as independently tested by a particular licensed engineering testing organization, which should be identified and incorporated therein by reference.
Once Class-A fire-protection has been delivered to substantially all of the exposed wood surfaces in a specific completed wood-framed or mass timber building section, the mobile computing system 117 can use its application 120 to make a request for carbon quantization of the completed fire-protected wood section by reading the identifying-code symbol on the barcoded/RFID-tag inspection checkpoint 300 posted on the door header of the completed building section. In response to this request, carbon quantization engine 500 will automatically service the request as illustrated in FIGS. 7 and 8A, and the process described in FIGS. 8B and 9 will be performed automatically and transparently, and the computed fire-protected carbon unit (FPCU) figure for the completed section will be displayed, and labels printed to be added to the inspection checkpoint 300, for subsequent certification and verification, if and as required for the application at hand. All FPCU figures and requests are indexed to the identifier associated with the barcoded/RFID-tagged inspection checkpoint 300, along with parameters and BIM models uploaded by the builder and its construction engineers and managers, with appropriate prompts and timing to support the carbon quantization process of the present invention.

Specification of Method of Verifying and Documenting On-Site Spray-Applied Class-A Fire-Protection Over Wood-Framed Buildings During Construction Using the On-Site Wood-Frame CFIC Liquid Spraying System
FIGS. 60A and 60B describe a method of verifying and documenting on-site spray-applied Class-A fire-protection over wood-framed buildings during construction using the on-site wood-frame CFIC liquid spraying system 100 shown in FIGS. 49 through 53. A description of this method is appropriate at this juncture.
As indicated at Block A in FIG. 60A, after a builder completes each predetermined section of a wood-framed building where wood-framing has been constructed and (plywood or OSB) sheathing installed, but before any wallboard has been installed, the spray technician uses an airless liquid spraying system 101 filled with clean fire inhibiting chemical (CFIC) liquid to spray the CFIC liquid over all exposed interior wood surfaces in the completed section of the wood-framed building.
As indicated at Block B in FIG. 60A, when the completed section of the wood-framed building is spray coated with CFIC liquid, the completed wood-framed building section is certified and marked as certified, with a barcoded/RFID-tagged inspection checkpoint 300 (with certificates of spraying and inspection) mounted at checkpoint locations in the completed section of the building, then certified and verified with signatures by the spray applicator and on-site spray supervisor manager (and optionally building site superintendent), and digitally documented by scanning and data capturing photos and/or audio-video recordings of the signed inspection checkpoint event, as shown in FIGS. 51A and 51B and FIGS. 63 and 64, and using the mobile application 120 for uploading the captured documents to the barcoded-project folder in the network database 113A on the system network 100, for subsequent visual inspection and insurance documentation purposes, as shown FIG. 61. Fire-protected carbon units (FPCUs) are estimated and recorded in the network database 113A using the carbon quantization engine 500 over the network 100 of the present invention. At this stage, the mobile application 120 running on a mobile computer 117, 137 can be used to make a request for carbon quantization of the wood used in the completed wood-framed or mass timber building section. By making such a request, the fire-protected carbon (mass) units that are stored in the fire-protected wood will be automatically estimated, recorded and reported using the carbon quantization engine 500 running over the network 100 of the present invention.
As indicated at Block C in FIG. 60A, as each section of the wood-framed building is constructed according to the construction schedule, the spray coating team continues to spray coat the completed section with CFIC liquid (e.g. Hartindo AF31), and certify and mark, using barcoded/RFID-tagged certificates of inspection (at inspection checkpoints) 300, each such completed spray coated section 118 (118A, 118B, 118C) of the building under construction.
As indicated at Block D in FIG. 60B, when the spray project is completed, the spray technician and supervisor then issue a time/date stamped “certificate of completion” certifying that clean fire inhibiting chemical (CFIC) liquid spray has been applied to all exposed interior wood surfaces on the interior of the wood-framed building during its construction phase, thereby providing the sprayed wood-framed building with Class-A fire-protection and defense against risk of total destruction by fire.
As indicated at Block E in FIG. 60B, before applying gypsum board and/or other wall board covering over the fire-protected spray-coated wood-framed building section 118, the mobile application 120 on mobile computing device 117 is used to capture and collect digital photographs and/or videos showing certificates of inspection at inspection checkpoints 300 posted on spray-coated fire-protected sheathing and/or lumber used in the wood framing of each completed building section, as visual evidence and job-site completion documentation, required or desired by insurance companies and/or government building departments and/or safety agencies. Preferably, each completed section of the wood-framed building should be assigned a section number by the builder, and if not by the builder, then by the spray application administrator, so that each certificate of completion, stamped on the wood surface of each section of the wood-framed building, and signed and dated by the on-site CFIC liquid spray applicator and on-site manager, will be digitally captured as images and/or AV recordings, and then uploaded to the system network database under the project ID number for project verification and documentation purposes.
As indicated at Block F in FIG. 60B, uploading captured digital photographs and videos collected during Block E to the centralized network database 113A on the system network 100, maintained by the fire-protection spray coating technician company, or its agent, as a valued-added service provided for the benefit of the property/building owner, builder, architect, home-owner and/or insurance companies involved in the building construction project.
As indicated at Block G in FIG. 60B, archiving all photographic and video records collected during Block E and uploading to the centralized web-based information server 111 at Block F for best practice and legal compliance purposes.
As indicated at Block H in FIG. 60A, when all sections of the building under construction have been completely spray coated with CFIC liquid, and certified as such, the spray technicians remove the spray equipment from the building, and the builder proceeds to the next stages of construction and completes the building construction according to architectural and building specifications and plans.
By virtue of the Web-based system network 100 described above, it is now possible for professional fire-protection specialists to (i) visually document the spraying of CFIC liquid over all exposed interior wood-surfaces of a wood-framed building under construction so as to achieve Class-A fire-protection, and (ii) after certifying with signatures, the proper on-site spray application of CFIC liquid, and Class-A fire-protection treatment of the wood-framed building, to capture and upload digital photographs and AV-recordings of certificates and related stamps, markings and signatures to a centralized website (e.g. system network database 113A), at which such uploaded and archived digital documents can be reviewed and downloaded when needed by architects, insurance companies, their inspectors, building owners, governmental officials, fire marshals and others who have a stake or interest in the matter of building fire-protection compliance and authentication. This remotely accessible facility, supported by the system network 100 of the present invention, provides a valuable and useful service to property/building owners, insurance underwriters, financial institutions (e.g. banks), and others who have great stakes in ensuring that particular wood-framed buildings have been properly Class-A fire-protected using the spray-treatment methods of the present invention described in great detail hereinabove.
Specification of an Exemplary Embodiment of the System Network of the Present Invention Used During the Management of the Logistical Operations and Certifications Made and Documented During Class-A Fire-Protection Spray Treatment of Wood-Framed Buildings During the Construction Phase
The system network 100 of the present invention has been described in great detail above in connection with ways in which to verify and document the CFIC liquid spray treatment of wood-framed buildings on job sites during the construction phase, so that the various stakeholders will have remote access to a secure database 113A containing photographic and audio-visual recording documentation, relating to certifications, verifications and documentation of each CFIC liquid spray project managed using the system network 100 of the present invention. However, when practicing the present invention, it is understood there will be many different ways to implement the useful concepts embraced by such inventions, when deploying and using a system network 100 to manage such operations across any enterprise of local, national or global scope. To help teach those with ordinary skill in the art to practice the present invention, an illustrative embodiment will be described at this juncture with reference to FIGS. 61A through 64.
FIG. 61A shows architectural floor plans for a wood-framed building scheduled to be sprayed with CFIC liquid to provide exposed interior surfaces with Class-A fire-protection. These floor plans will be uploaded and stored in the network database 113A in the document folder/directory of the project. FIG. 61B shows architectural floor plans for an exemplary wood-framed building, with a section marked up by the builder (indicated in dark thick lines), and scheduled to be sprayed with CFIC liquid to provide Class-A fire-protection. FIG. 61C shows marked-up architectural floor plans indicating a completed section that has been sprayed with CFIC liquid to provide exposed interior surfaces with Class-A fire-protection. All such marked-up floor plans will also be stored in the network database 113A as part of the project's document package, as will be explained in greater detail herein below.

The system network 100 and its distribution of mobile computing devices (running mobile application 120 or web-browser equivalents) will have the capability to list all spray projects linked to the user, wherein each project contains numerous project details and information of different relevance to different stakeholders. In the illustrative embodiment, all projects will be searchable by customer name then project name. The building owners (often referred to as the “customer” with respect to the spray contractor) will only be able to access their projects, not the projects of others which will be maintained confidential on the system network 100. The mobile application 120 will be able to send push-notifications where required, and users will choose what notifications they want to receive. For example, the customer's insurance company will have the option to only be notified when a portion of the building has been sprayed, or when only an entire floor has been sprayed.
Upon creating a new project on the system network 100, the spray project coordinator will use the mobile application 120 to add various information items regarding the project, in the network database 113A, including, for example: Customer Name (e.g. Building Owner Name); Project Name; Site Address; Superintendent's name and title, mobile number, email address; number of buildings associated with the project.
The mobile application 120 will then start with building 1 or building A, and prompt the user for the following information: Identify Building Type—by choosing a type from a drop down menu (i.e. apartment, townhouse, house, etc.). If the Building Type is an apartment, then the user will be asked to describe the building (i.e. 3, 4 or 5 stories, square footage, total number of suites).
Mobile application 120 has the capability to import one or more pdf documents of each floor plan of the building into the project folder on the network database 113A, as shown in FIG. 62A. At this stage, the mobile application 120 will ask the user to import one or more pdf document(s) of the floor plan of each floor in the building, and will ask to identify the building, floor, and provide other information for subsequent use and marking. In particular, the application servers 112 will support advanced pdf document processing software enabling the users to index imported building floor plans to indicate the precise location where barcoded/RFID-tagged inspection checkpoints 300 (with integrated certificates of spraying, certificates of inspection) shown be posted during the project, as shown in FIGS. 62 and 63, for purposes of illustration.
The mobile application 120 will also request from the spray project coordinator, a Project Start Date when spray technicians should be begin spraying, in coordination with the construction schedule. Once the project has been created, the mobile application 120 will automatically send a push notification to: CFIC supply manager; building site coordinator; and spray administrators. Each user will be invited to project, with certain rights and privileges as determined and set by the spray project administrator (i.e. fire-protection provider administrator).
When the barcoded/RFID-tagged CFIC totes 181, 181′ shown in FIGS. 64 and 76, are ready to be filled or shipped, the mobile application 120 will prompt the CFIC Supply Manager 186 for various items of information relating to CFIC material required on certain building sites, in connection with specific projects. The user will navigate to the project on the mobile application 120, and will store the CFIC tote 18, 181′ information that multiple CFIC totes 181 are required per project. For purposes of the present invention, the term “tote” shall mean any device fashioned to contain and hold a predetermined quantity of CFIC material, whether in dry power form, or concentrated liquid form, and may include bags, containers, bottles, or any other type of vessel capable of perform functions of containment and carrying. Each barcoded/RFID-tagged CFIC tote 181, 181′ shall have a locking mechanism, preferably a combination-type lock but may be realized using a key-based mechanism, to keep unauthorized individuals from opening the lock and accessing the chemical contents contained with the barcoded/RFID-tagged CFIC tote 181, 181′. Estimates of CFIC material, based on the size of the building spray job, can be calculated using tables and other knowledge possessed by the CFIC supply chain manager, and may be automated using AI-based processes. In an illustrative embodiment, the user will select one of the following buttons; Add a CFIC Tote; Ship A CFIC Tote. If the user selects “add a CFIC tote” then they will be prompted for the following; the date (chosen from a calendar), the CFIC tote number, the size of the CFIC tote, dye (yes or no) mold protection (yes or no). If the user wants to “ship a CFIC tote”, then the user navigates to the project and selects the “ship a CFIC tote” button and chooses the CFIC tote the user wants to ship from a drop-down menu. The user will then pick a date from a calendar. The user will have to enter the ship date and the arrival date and name of the shipping carrier.
Once the CFIC tote 181, 181′ arrives at building job-site, the building site supervisor will log into the system network via the mobile application 120, and perform the following system network operations. The building site supervisor (i.e. customer) will navigate to the project on the mobile application 120, and sign off that the CFIC tote has arrived at the job site, with its locks intact and that CFIC tote 181, 181′ has not been tampered. The site supervisor will use his/her finger to sign this confirmation in the mobile application 120.
When the building owner (i.e. customer) wants to request a completed portion or section of a wood-framed building to be sprayed-treated with CFIC liquid, the building site supervisor will perform the following system network operations. The building site supervisor use the mobile application 120 to navigate to their project and enter the portion of their building they want sprayed with CFIC liquid. The building site supervisor will indicate the date the request was made, building number, the floor and the suites they want sprayed and date they want it sprayed. The mobile application 120 will send a notification via the mobile application 120 to the project coordinator, to let them know the request has been made. The spray project coordinator will use the mobile application 120 to either accept the requested spray date, or propose a new spray date to the building site supervisor. If the spray project coordinator (i.e. fire protection provider) accepts the proposed spray date, then a confirmation will be sent to the building site superintendent via the system network using the mobile application 120.
Once the spray contractors (i.e. fire protection providers) arrive on-site of the building and are ready to spray CFIC liquid as requested, the site spray technician will perform the following operations in the system network 100 using the mobile application 120. The site spray technician will mix a CFIC tote 181, 181′ (e.g. by adding water to a tote contain CFIC liquid concentrate, or by adding water to the tote containing AAF31 powder and dye, if the project requires dye). If the project requires mold protection, then that chemical component will be added at the time the CFIC tote is mixed on site), and the spray technicians will sign in to the mobile application 120, navigate to the project page, and click on “on-site CFIC tote preparation”. The spray technicians will choose the CFIC tote identification number from the drop-down list (previously updated by the CFIC supply chain manager 186) and then enter the date, by clicking on a calendar date. The spray technicians will indicate if they have added dye, and or mold protection to the CFIC material.
When the spray date arrives, the building site superintendent will do a walk through of the intended spray area (i.e. floor plan) and inspect to make sure the area is ready to spray all exposed interior wood surfaces with CFIC liquid. The building site superintendent will attach an RFID tag and/or bar code symbol label at each inspection checkpoint 300 marked on the floor plans of the wood-framed building to be spray-treated with CFIC liquid spray, indicated in FIG. 61B. Each RFID tag and/or bar code symbol will be encoded with a unique code identifier that is marked on the floor plan, and uniquely associated with the project, and added to the network database 113A on the system network.
Preferably, the spray site superintendent will mount a barcoded/RFID-encoded inspection checkpoint 300 (bearing a certificate of spraying by the spray technician and a certificate of inspection by the spray supervisor and optionally the building site supervisor, printed on a thin flexible plastic sheet, on which a barcode symbol/RFID-tag are mounted) to (i) the entry door header of each room in each unit including the entrance to the unit, as illustrated in FIG. 62, and also (ii) a stud located at every 10′ on one side of the hallway. Expectedly, the location of each barcoded/RFID-tagged inspection checkpoint 300 in any given project will vary. However, placement of such inspection checkpoints 300 should be selected to ensure that inspection is sufficient granular in resolution to not overlook significant areas of a sprayed wood-framed building section under inspection.
Each barcoded/RFID-tagged inspection checkpoint 300 will include a bar code symbol and RFID tag that has a unique project/inspection-checkpoint identifier (e.g. an alphanumeric character string) encoded into the zymology used in the barcode symbol and RFID tag identifier, and this project/inspection-checkpoint identifier will be used to identify subfolders or subdirectories where collection data, information and documents are stored in the project folder on the network database 113A, maintained on the system network 100. The project/inspection-checkpoint identifier will be read during each scan/read of the barcoded/RFID-tag inspection checkpoint 300, and used by the mobile application to access the appropriate inspection checkpoint folder in the project folder where all such certifications of spraying, inspection and oversight, and photos, and videos are stored and archived for posterity.
At the beginning of each spray session, the spray technician will log into the system network 100 using the mobile application 120, then navigate to the project page, select his name from a drop down or scrolling list, and indicate when he started spraying by clicking on a date and hour, minutes, seconds. The spray technician may also need to scan his barcoded ID card using the mobile application 120 for proper authentication and/or authorization purposes. He may also choose to record the presence of other members of his spray crew using the mobile application and their barcoded user ID cards and network ID numbers. The spray technician will then proceed to spray each assigned section of the building, and during the spray process, the spray technician and/or supervisor may wear a head-mounted digital color camera 120C wirelessly interfaced to his/her mobile computing system 117, while running the mobile application 120, to capture live digital color video footage of the complete fire-protection spray process. the captured digital video recording of the fire protection spray process on each completed wood-framed section will be subsequently uploaded to and stored within the project folder maintained on the network database 113A in the data center 110. This video recording, and the signed confirmations and verifications captured and recorded as well during the fire protection spray project will also be stored in the network database 113A in the project folder and made available to fire insurance risk engineers and underwriters at a subsequent date, to confirm that the wood-framed building was in fact professional fire-protected on a given date/time.
After spraying each wood-framed building section, the spray technician will approach the barcoded/RFID-tagged inspection checkpoint 300 in the spray area, and read, sign and date the certification of spraying on the checkpoint substrate, mounted on the header surface illustrated in FIGS. 62 and 63. The spray technician should diligently read, sign and date each and every certificate of spraying at the inspection checkpoint 300, and treated as a condition of professionalism, duty, and employment, given the responsibility being entrusted to the individual with such operations.
At the end of the day, the spray technician will log into the system network 100, if already logged out, using the mobile application 120, and indicate the time when he finished spraying and indicate which suites on the floor plan pdf were sprayed with CFIC liquid. This will be done by drawing on his mobile computing device 117 (e.g. Apple iPad or Apple iPhone), by shading the PDF of the floor plan, over the appropriate suites and hallways, as shown in FIG. 61C, which were in fact sprayed with CFIC liquid during his work session that date. This is the same floor plan that was previously loaded on the mobile application 120 by the customer/building owner, as shown in FIG. 61A, but with the spray technicians markings added to the floor plan to indicate sections which have been spray treated with CFIC liquid.
At the end of each day or during the course of the day, the spray site superintendent will review the CFIC liquid spraying work performed on the job site that date, to ensure that the spray work has been completed properly.
The spray supervisor will visit each checkpoint 300, and read, sign and date the certificate of inspection at the inspection checkpoint 300 after performing a diligent inspection at and around the checkpoint where spraying occurred earlier that day. At each barcoded/RFID-tagged inspection checkpoint 300 on the plan, the spray site supervisor will also scan each and every barcoded/RFID-tag inspection checkpoint 300, and confirm with the system network 100 that the spray work at each inspection checkpoint has been completed properly. This process will involve displaying GUI screens on the mobile application 120 and checking off all suites/units and hallways have been completed and sprayed with CFIC liquid, and uploading such information to the project folder on the network database 113A on the system network 100. The process can also include capturing digital photos and AV-recordings of the site in the vicinity of each barcoded/RFID-tagged inspection checkpoint, verifying and documenting the certifications at each inspection checkpoint signed by the spray-technician after CFIC liquid spraying, and then uploading these captured digital photos and AV recordings to the project under the inspection checkpoint ID, within the network database 113A maintained by the system network 100.
Also, it is desired that the building site superintendent visit each checkpoint and read, sign and date the certificate of inspection/oversight by the building superintendent on the job site on that date. The building site superintendent should also use the mobile application 120 to capture digital images and videos of this certificate and competed inspection checkpoint, and surrounding areas treated with CFIC liquid by the spray technician. Images and video recordings of the spray technician and supervisor can be included at each and every barcoded/RFID-tagged inspection checkpoint 300 and uploaded to the project folder, under the barcoded/RFID-tagged inspect checkpoints 300 assigned to the project.
The above steps above will be repeated every time the spray crew arrives at the building site until the project is complete.
Each time a CFIC tote 181, 181′ is mixed at the job site by the spray technician, he/she will spray six 1-foot long 2×4's test boards (301A, 301B) covering all sides (e.g. 3 sprayed test boards for spray administrator and 3 sprayed test boards for the customer). The sample test boards 301 will be marked with the tote number. Alternatively, CFIC liquid sprayed test boards 301 can be made at or near barcode/RFID-tagged inspection checkpoints 300 in the building, and marked with the barcode/RFID ID number, and date they were sprayed. The fact that these sample test boards 301 were created will be recorded using the mobile application 120 in either the CFIC tote supply record section of each project, or under a barcode symbol/RFID-tag ID section of the project. Digital images and videos of these sprayed test boards 301 can be captured and uploaded to project folder in the network database 113A maintained on the system network 100.
At the completion of the project, the spray site superintendent will check the box that the project is complete. The spray site superintendent will request the building project superintendent to sign that the project has been completed, and such documentation will be made part of the project files stored in the network database 113A on the system network 100. A physical certificate of completion document can be signed and dated and scanned into pdf format and stored in the project file in the network database 113A, using the mobile application 120 deployed on the system network 100. Once each stage of project has been completed (e.g. certain completed sections of the wood-framed building are completed), the system network 100 will automatically send an email, SMS/text and/or phone notification to the local fire department, local police department, the insurance underwriting company, the building owner (i.e. customer), and the spray project coordinator, and record all such notifications in the network database 113A for archival purposes. Such notifications will also be issued automatically by the system network's servers once the entire project has been completed, along with its certification of project completion. The system network 100 will automatically organize all documents, data and information collected during the course of the project, and compile for presentation to various parties including the building owner, and property insurance underwriters. The notifications provided to the above-mentioned parties, particularly the local fire departments and police departments, will be of great assistance in (i) instantly advising them which sections of any wood-framed building under construction in their jurisdiction has actually received Class-A fire-protection using the method of and apparatus of the present invention, and (ii) providing collected documents certifying such Class-A fire-protection, in the event that a fire should break out on in the wood-framed building during construction, and/or at any time after construction has been completed, and the building has received its certificate of occupancy.
The site spray technician will then collect all the sprayed samples 301A, 301B stored in barcoded storage sleeves 302A, 302B and deliver the first set of test samples 301A to the building site superintendent or the building's architect, while providing the second set of the sprayed test samples 301B to the spray supervisor to transport and archive in storage, as part of the fire protection provider's legal and business records. The spray technician will certify that he has provided the first set of sprayed test samples in storage sleeves to the building site superintendent, and the second set of sprayed test samples to the spray site superintendent. The building site superintendent will sign that he has received the sprayed test samples in their barcoded storage sleeves. The second set of sprayed test samples can be shipped to the fire protection provider's warehouse for archival purposes.
Method of Qualifying a Wood-Framed Building for Reduced Property Insurance Based on Verified and Documented Spray-Based Clean Fire Inhibiting Chemical (CFIC) Liquid Treatment of all Exposed Interior Wood Surfaces of the Wood-Framed Building During the Construction Phase Thereof
FIG. 63 shows the high-level steps required to practice the method of qualifying a wood-framed building for reduced property insurance based on verified and documented spray-based clean fire inhibiting chemical (CFIC) liquid treatment of all of the exposed interior surfaces of the wood-framed building, after each completed section.
As indicated at Block A in FIG. 63, a clean fire inhibiting chemical (CFIC) liquid is sprayed all over all interior surfaces of each completed sections of a wood-framed building to provide Class-A fire-protection, as described above in FIGS. 60A and 60B, using the GPS-tracked/GSM-linked mobile clean fire-inhibiting chemical (CFIC) liquid spraying system 101, as shown in FIGS. 49, 50, 50 and 50B.
As indicated at Block B in FIG. 63, the spray-based class-A fire protection treatment process is verified and documented by capturing (i) GPS-coordinates and time/date stamping data generated by the GPS-tracked CFIC liquid spray system 101 deployed on the system network, and (ii) digital images, and audio-video (AV) recordings of certificates of completion 181 stamped on completed sections after spray treatment, as illustrated in FIGS. 51A and 51B, using the mobile application 120 on mobile computing device 117.
As indicated at Block C in FIG. 63, the collected on-site spray treatment verification data is wirelessly transmitted to a central network database 113A on the system network to update the central network database on the system network 109.
As indicated at Block E in FIG. 63, a company underwriting property insurance for the wood-framed building accesses the central network database 113A on the system network 100, to verify the database records maintained for each wood-framed building that has undergone spray-based Class-A fire protection treatment, to qualify the building owner for lower property insurance premiums, based on the verified Class-A fire-protection status of the sprayed-treated wood-framed building.
As indicated at Block E in FIG. 63, upon the outbreak of a fire in the insured wood-framed building/property, the local fire departments instantly and remotely assess the central network database 113A using a mobile application 120, so as to quickly determine Class-A fire-protected status of the wood-framed building by virtue of CFIC liquid spray treatment of the wood-framed building during the construction phase, and inform fireman tasked with fighting the fire that the wood-framed building has been treated with Class-A fire-protection defense against fire.

FIG. 64 illustrates the supply chain management and quality control process supported by the system network of the present invention, shown in FIG. 55. As shown, the CFIC tote chain of custody and tracking system application is deployed to manage and control the weight of the contents in each CFIC tote from the time of shipment to time of arrival at the customer job site where the CFIC is received from the chemical factory or warehouse, and either accepted or rejected depending on the comparative weight measurements of the shipped CFIC totes made at the receiving job site using a digital code scanning and weighing scale system (SWS).
FIG. 64A is a schematic diagram illustrating the weighing of CFIC liquid totes at chemical factory before shipment and recording tote weight in supply chain management database.
FIG. 64B is a schematic diagram illustrating the weighing CFIC liquid totes at building construction job site 111A (111B, 111C), and recording tote weight in supply chain management database before acceptance.
FIGS. 65A, 65B, 65C and 65D describes the high level steps carried out in a method of maintaining the chain of custody, quality control, tracking and inventory when producing and supplying clean fire inhibiting chemical (CFIC) material (e.g. liquid or dry powder) in locked CFIC totes (e.g. 5 gallons) 181 shipped from chemical factory 180 to a network of building construction job sites 111A (111B, 111C), as illustrated in FIG. 64.
As indicated at Block A in FIG. 65A, a supply chain manager 186 shown in FIG. 64 issues a purchase order (PO) to a chemical factory system 180 for the production and delivery of clean fire inhibiting chemical (CFIC) liquid to a building construction job site 111A (111B, 111C) or warehouse 187, as shown in FIGS. 64B and 67A, for fire protecting a wood frame building through the spray process of the present invention. Notably, the supply chain manager 186 can be a human being, or an automated or artificially-intelligent (AI) computer system programmed to determined the amount of CFIC liquid required to treat all wood on a particular building construction job site 111A (111B, 111C), with an estimated amount of wood surface area requiring Class-A fire protection.
As indicated at Block B in FIG. 65A, the purchase order (PO) is received and processed, and the quantity of CFIC liquid (e.g. measured in gallons/square foot) is determined required to fulfill the purchase order.
As indicated at Block C in FIG. 65A, one or more CFIC powder or liquid containing totes 181 are procured to fulfill the purchase order, either by (i) blending CFIC power and/or liquid and filling up, and CFIC totes 181, and/or (ii) removing one or more CFIC totes from inventory maintained in a warehouse 187 as shown in FIG. 64. In the illustrative embodiment, each CFIC tote 181 has a combination lock mechanism that prevents others without the lock code from accessing the chemical contents of the CFIC tote 181.
As indicated at Block D in FIG. 65A, barcoded/RFID-tagged shipping labels 200 are generated for the shipment. In general, each barcoded/RFID-tagged shipping labels 200 comprises barcode 200A and RFID-tag 200B. In the illustrative embodiment, each shipping label 200 includes the purchase order identification number contained in the purchase order. Preferably, the barcode and RFID-tag code structures will encode the purchase order identification number in one way or other, or be linked to this identification number using suitable techniques.
As indicated at Block E in FIG. 65A, the barcoded/RFID-tagged shipping labels 200 are applied on the CFIC totes 181. In some embodiments, one or more of these identification components 200A, 200B will be used for auto-identification of each CFIC tote 181 used on the system of the present invention.
In general, various kinds of barcode symbol and RFID-tag technologies can be used to realize the barcoded/RFID-tagged shipping labels 200 comprising barcode 200A and RFID-tag 200B. Various RFID-labels, RFID-tags and barcode labels are available from Zebra Technologies, Inc., Holtsville, NY. Also, Zebra Technologies provides hand-held mobile computers, wearable computers, vehicle-mounted computers, tablets and hand-held RFID readers (i.e. mobile computing devices 117), and barcode symbol, RFID-label and RFID-tag printers and readers (i.e. scanners) for use in practicing the principles of the present invention disclosed herein.
As indicated at Block F in FIG. 65B, before shipping to its designation, each barcoded/RFID-tagged shipping labels 200 is scanned using a code symbol reader/scanner integrated within the mobile computing device 117 as shown in FIG. 67B, then after a database socket connection is established, each barcoded/RFID-tagged CFIC tote 181 is weighed and its GPS coordinates are captured by the mobile computing device 120, and then its measured weight and GPS coordinates are uploaded and recorded in a centralized supply chain management database 113A, supporting fields illustrated in FIG. 66A.
As indicated at Block G in FIG. 65B, each barcoded/RFID-tagged CFIC tote 181 is shipped to its designation building construction job site 111A, or warehouse, for receipt by a particular licensed recipient, as shown in FIGS. 64B and 67D. For purposes of the present invention, the recipient can be any one of various possible entities including, for example, a dealer licensed to apply CFIC liquid on interior wood-framed building surfaces, a builder licensed to apply CFIC liquid on interior wood-framed building surfaces, or other contractor applying
As indicated at Block H in FIG. 65B, each shipped barcoded/RFID-tagged CFIC tote 181 is received its destination job site as shown in FIG. 67E, its barcode/RFID-tag 200 is scanned using a code symbol scanner supported by mobile computing system 117 as shown in FIG. 67F, and then the mobile application 120 automatically accesses the centralized supply chain management database 113A in data center 145, the weight of the scanned barcoded/RFID-tagged CFIC tote 181 is weighed, and its measured weight is uploaded recorded in the centralized supply chain management database 113A as illustrated in FIG. 67G.
As indicated at Block I in FIG. 65C, the mobile application 120 running on the mobile computing system 117 is used to compare the weights of each shipped barcoded/RFID-tagged CFIC tote 181, and apply the following rules:
- (i) if the weight difference is within a predetermined threshold (e.g. 5 oz.), then the received barcoded/RFID-tagged CFIC tote 181 can be accepted at the destination job site and receipt of shipment is indicated in the centralized supply chain management database 113A, as illustrated by the database fields reflected in FIG. 66B, and illustrated in FIG. 67H; and
- (ii) if the weight difference is above the predetermined threshold, then the received barcoded/RFID-tagged CFIC tote 181 is rejected at the destination job site and that the shipment has been rejected is indicated in the centralized supply chain management database 113A as shown in FIG. 67I.
As indicated at Block J in FIG. 65C, in the event the CFIC tote weight measurement was within the predetermined threshold, using the mobile application 117 running on mobile computing device 117 (e.g. Apple iPhone or iPad tablet computer) the barcoded/RFID-tagged CFIC tote 181 is automatically registered and added to the recipient's inventory maintained within the supply chain management database 113A, as illustrated in FIG. 67H. In the event CFIC powder material is contained in the CFIC tote 181, then the end user will add the required amount of clean water to make the CFIC liquid for spraying on wood surfaces on the wood-framed building at the destination job site 111A (111B, 111C).
As indicated at Block K in FIG. 65C, one or more barcoded/RFID-tagged CFIC totes 181 are transported from the recipient's inventory to a particular job site 11A where a wood-framed building is under construction.
As indicated at Block L in FIG. 65D, a spray site administrator or spray technician uses a mobile application 120 on a mobile computing device 117 to scan the barcode 200A (or read the RFID-tag 200B) on each CFIC tote 181 as the CFIC tote is being used on the job site, and to automatically check out the specifically-identified CFIC 181 tote using scanned code information from the recipient's inventory maintained in the supply chain management database 113A at the data center 145, shown in FIGS. 55, 64 and 64B.
As indicated at Block M in FIG. 65D, the mobile application 120 is used to automatically detect and record the GPS coordinates of the barcode-identified CFIC tote 181 where it is to be used and sprayed on the job site 111A, for documentation purposes under a licensing program so as to ensure that the CFIC tote 181 is being used by the recipient within a licensed territory, as illustrated in FIG. 67K. Documentation of specific CFIC totes 181 used on a specific job site will become part of the chain of documents capture during the lifecycle of the wood-framed building under construction, and being treated so that its wood is rendered Class-A fire-protected under ASTM E84 test standards. Such documentation will be valued and appreciated by the property insurance industry who is involved in underwriting property insurance policies on such kinds of new wood-framed building construction, and granting premium discounts to building owners who have actually lowered the fire risk profile of the building by application of Class-A fire-protection to substantially all wood surfaces used in construction of a particular insured building structure, regardless of size or location, in accordance with the principles of the present invention.
As indicated at Block N in FIG. 65D, the mobile application 120 automatically generates an inventory replenishment order if and when the recipient's CFIC tote inventory is determined to fall below a threshold inventory level (e.g. 50×50 gallon CFIC totes 181) maintained by the supply chain management network database 113A, as illustrated in FIG. 67L. If a replenishment order is generated, then the supply chain manager 186 will automatically generate and send a purchase order to the CFIC factory 180 to fulfill the order for a specified quantity of CFIC totes 181 and ship a requested quantity of CFIC totes 181 to the recipient's job site location, or local warehouse location, for use in Class-A fire protection job site spraying.

It is understood that, in many embodiments, the above-described enterprise-level system 135, supporting wood framed and mass-timber building factories 130 around the globe, will also include a core integrated financial accounting system 400. This core integrated financial accounting system 400 will be supported by a general ledger system (GLS), an accounts payable system (APS) and an accounts receivable system (ARS). The financial accounting system can be hosted in the data center 145 or elsewhere on the Internet, in a manner well known in the art. Integrated financial accounting software system solutions are available from numerous vendors including, but not limited to, for example, Oracle's NetSuite® Financial Management Software System, SAP's Business Financial One Software System, etc.
As shown in FIG. 66, the system also includes a GPS system 139 for transmitting GPS reference signals transmitted from a constellation of GPS satellites deployed in orbit around the Earth, to GPS transceivers installed aboard each GPS-tracking ISO-shipping containers 136A, 136B, as part of the illustrative embodiments. From the GPS signals it receives, each GPS transceiver is capable of computing in real-time the GPS location of its host system, in terms of longitude and latitude. In the case of the Empire State Building in NYC, NY, its GPS location is specified as: N40° 44.9064′, W073° 59.0735′; and in number only format, as: 40.748440, −73.984559, with the first number indicating latitude, and the second number representing longitude (the minus sign indicates “west”).
FIG. 67 shows the mobile client computing system(s) 137, 137′ used in the system network 135 shown in FIG. 63, supporting mobile application 153 installed on each registered mobile computing system 137, 137′. The purpose of the mobile application 153 is to provide a convenient tool for tracking and managing projects involving factory-applied clean fire inhibiting chemical (CFIC) liquid dip-infusion treatment of wood pieces during the prefabrication of Class-A fire-protected wood-framed buildings. In the event that CFIC liquid solution is mixed on site by adding water to pre-blended dry powder chemicals at a toll blender, the mobile application can be used to track chain of custody from our toll blender to the factory site where the toted power mixture is added to water to produce an aqueous-based CFIC liquid solution, for high-speed dip-infusion 100% of all wood/lumber used to fabricate Class-A fire-protected wood-framed building components along production lines inside the factory 130 shown in FIGS. 65A, 65B and 66.
Using the custom-designed mobile application 153 of the present invention, prefabricated building purchasers, builders and architects alike can track the progress being made while an order for a prefabricated Class-A fire-protected wood-framed building is being executed as a prefabricated wood-framed building project. During the process, all wood pieces used to fabricate each wood-framed building component is automatically dip-coated in a tank of CFIC liquid, as shown in FIGS. 19A, 23A, 27A, and 33A, in a just-in-time manner, during the building fabrication schedule, so as to provide 100% Class-A fire-protected wood-framed building components. These components can then be used in constructing Class-A fire-protected prefabricated wood-framed buildings. The mobile application 153 can be used to review all collected digital images, and audio and visual evidence of certificates, stamps, signatures and verifications during the course of the just-in-time prefabrication building project.

As shown in FIG. 67B, the mobile computing device 137 (137′) can include a memory interface 202, one or more data processors, image processors and/or central processing units 204, and a peripherals interface 206. The memory interface 202, the one or more processors 204 and/or the peripherals interface 206 can be separate components or can be integrated in one or more integrated circuits. The various components in the mobile device can be coupled by one or more communication buses or signal lines. Sensors, devices, and subsystems can be coupled to the peripherals interface 206 to facilitate multiple functionalities. For example, a motion sensor 210, a light sensor 212, and a proximity sensor 214 can be coupled to the peripherals interface 206 to facilitate the orientation, lighting, and proximity functions. Other sensors 216 can also be connected to the peripherals interface 206, such as a positioning system (e.g. GPS receiver), a temperature sensor, a biometric sensor, a gyroscope, or other sensing device, to facilitate related functionalities. A camera subsystem 220 and an optical sensor 222, e.g. a charged coupled device (CCD) or a complementary metal-oxide semiconductor (CMOS) optical sensor, can be utilized to facilitate camera functions, such as recording photographs and video clips. Communication functions can be facilitated through one or more wireless communication subsystems 224, which can include radio frequency receivers and transmitters and/or optical (e.g. infrared) receivers and transmitters. The specific design and implementation of the communication subsystem 224 can depend on the communication network(s) over which the mobile device is intended to operate. For example, the mobile device 137 may include communication subsystems 224 designed to operate over a GSM network, a GPRS network, an EDGE network, a Wi-Fi or WiMax network, and a Bluetooth™ network. In particular, the wireless communication subsystems 224 may include hosting protocols such that the device 137 may be configured as a base station for other wireless devices. An audio subsystem 226 can be coupled to a speaker 228 and a microphone 230 to facilitate voice-enabled functions, such as voice recognition, voice replication, digital recording, and telephony functions. The I/O subsystem 240 can include a touch screen controller 242 and/or other input controller(s) 244. The touch-screen controller 242 can be coupled to a touch screen 246. The touch screen 246 and touch screen controller 242 can, for example, detect contact and movement or break thereof using any of a plurality of touch sensitivity technologies, including but not limited to capacitive, resistive, infrared, and surface acoustic wave technologies, as well as other proximity sensor arrays or other elements for determining one or more points of contact with the touch screen 246. The other input controller(s) 244 can be coupled to other input/control devices 248, such as one or more buttons, rocker switches, thumb-wheel, infrared port, USB port, and/or a pointer device such as a stylus. The one or more buttons (not shown) can include an up/down button for volume control of the speaker 228 and/or the microphone 230. Such buttons and controls can be implemented as a hardware objects, or touch-screen graphical interface objects, touched and controlled by the system user. Additional features of mobile smartphone device 137 can be found in U.S. Pat. No. 8,631,358 incorporated herein by reference in its entirety.
Different Ways of Implementing the Mobile Client Machines and Devices on the System Network of the Present Invention
In one illustrative embodiment, the enterprise-level system network 100 is realized as a robust suite of hosted services delivered to Web-based client subsystems 137 using an application service provider (ASP) model. In this embodiment, the Web-enabled mobile application 153 can be realized using a web-browser application running on the operating system (OS) (e.g. Linux, Application IOS, etc.) of a mobile computing device 137 to support online modes of system operation, only. However, it is understood that some or all of the services provided by the system network 100 can be accessed using Java clients, or a native client application, running on the operating system of a client computing device, to support both online and limited off-line modes of system operation. In such embodiments, the native mobile application 153 would have access to local memory (e.g. a local RDBMS) on the client device 137, accessible during off-line modes of operation to enable consumers to use certain or many of the system functions supported by the system network during off-line/off-network modes of operation. It is also possible to store in the local RDBMS of the mobile computing device 137 most if not all relevant data collected by the mobile application for any particular fire-protection spray project, and to automatically synchronize the dataset for user's projects against the master datasets maintained in the system network database 113A, within the data center 110 shown in FIG. 69. This way, when using an native application, during off-line modes of operation, the user will be able to access and review relevant information regarding any building spray project, and make necessary decisions, even while off-line (i.e. not having access to the system network).
As shown and described herein, the system network 100 of the present invention has been designed for several different kinds of user roles including, for example, but not limited to: (i) building purchasers, builders, and architects who might or will have the authority to place or make purchase orders online to commence a Class-A fire-protected wood-framed building project; and (ii) prefabrication building project administrators and technicians registered on the system network. Depending on which role, for which the user requests registration, the system network will request different sets of registration information, including name of user, address, contact information, information about wood-framed buildings, builders, architects, etc. In the case of a web-based responsive application on the mobile computing device 137, once a user has successfully registered with the system network, the system network will automatically serve a native client GUI, or an HTML5 GUI, adapted for the registered user. Thereafter, when the user logs into the system network, using his/her account name and password, the system network will automatically generate and serve GUI screens described below for the role that the user has been registered with the system network.
In the illustrative embodiment, the client-side of the system network 100 can be realized as mobile web-browser application, or as a native application, each having a “responsive-design” and adapted to run on any client computing device (e.g. iPhone, iPad, Android or other Web-enabled computing device) 137 and designed for use by anyone interested in managing, overseeing and/or monitoring on-site CFIC liquid spray projects involving owners of specific wood-framed buildings seeking Class-A fire-protection.

In one illustrative embodiment, the mobile application 153 and/or digital camera systems can be used to review digital images and audio-video (AV) recordings taken of CFIC liquid dipped-coated wood pieces along the production line, relating to prefabricated wood-framed building components 132 being fabricated, and uploaded to the system network database 113A under the project ID # of the prefabricated building project. All captured documents and evidence of CFIC liquid dip-coated wood can be uploaded, logged and time/date-stamped and stored into the project-specific document folder maintained on the system network database 148A of the system network 100 using document capture, time/date-stamping and cataloguing capabilities.
Alternatively, Class-A fire-protected lumber, and/or engineered wood products (EWPs), that are dip-coated in CFIC liquid, will be used to construct prefabricated Class-A fire-protected wood-framed building components 132 (e.g. wall panels, roof trusses, floor trusses, roofing systems, flooring systems, and stair assemblies). Once constructed in the factory on the production line, a barcoded/RFID-tagged inspection label 138 is applied to each and every prefabricated Class-A fire-protected wood-framed building component produced on the production line 131.
As shown in FIG. 68C, each barcoded/RFID-tagged inspection label 138 will include a bar code symbol 138A, and a UHF-Class RFID tag 138B, mounted on a label substrate, wherein the bar code symbol and RFID tag has a unique building-component identifier (e.g. an alphanumeric character string) encoded into the symbology used in the barcode symbol and RFID tag identifier, and this building-component identifier will be used to identify subfolders or subdirectories where collection data, information and documents are stored in a building-component subfolder (indexed with the building-component identifier), in the building-project folder on the network database 113A, maintained on the system network 110, shown in FIG. 69. The building-component identifier will be read during each scan/read of the barcoded/RFID-tag label 138B, and used by the mobile application 153 to access the appropriate building-component subfolder in the building project folder where all such certifications 138D of dip-infusion, inspection and oversight, and photos and videos, and signed confirmations and verifications of fire-protection services (e.g. CFIC were applied to specific wood objects by whom on specific dates) are stored and archived for fire risk engineering analysis, review, and other archival and auditing purposes.
As shown in FIGS. 68A, 68B and 68C, each prefabricated modular or panelized wood-framed or mass-timber building component 132 (132A, 132B) manufactured in a just-in-time wood-framed/mass-timber building factory 130 will be uniquely barcoded/RFID-tagged and tracked by the system network 100 of the present invention as described herein. Specifically, a unique barcoded/RFID-tagged label 138 will be permanently affixed to (i) each completed prefabricated wood-framed or mass-timber building module 132A, or (ii) each prefabricated building module 132B associated with a specific prefabricated wood-frame or mass-timber building, as the case may be, and a barcode-index documents folder will be maintained in the network database 113A at the data center 110, for storing collected images, videos, signed certifications and verifications from specific technicians who applied and/or oversaw the application of CFIC liquid to specific wood products to provide Class-A fire protection performance properties thereto during the factory manufacturing process, on specific dates, at specific GPS-indexed locations. The collected documents are stored in an indexed folder on the network database 113A, associated with the manufacture of a prefabricated building within in the factory system.
The system network of the present invention 100, and the services supported thereby, will provide fire and construction insurance underwriters, as well as fire risk engineers, easy remote access to data, documents and documentation to support the fire insurance underwriting process, in unprecedented manner, with regard to any wood-framed or mass-timber building that has received fire-protection in accordance with the principles of the present invention. The project folders supported within the network database 113A will contain signed documents by and photographs and videos of individuals who actually performed the professional services on specific time and dates, at specific GPS locations, confirming and verifying that such specific professional fire-protection services (PFPS) were performed on a specific wood-framed building which is the subject of a fire insurance policy be underwritten. All signed confirmations and verifications by such professional fire protection technicians are captured, uploaded and stored as GPS, data and time stamped documents in a network database system 113A, under a single project associated with a specific fire-protection services contract, upon which fire, construction and property insurance underwriters will have the confidence to grant insurance premium reductions (i.e. discounts or rewards) for confirmed and verified fire-risk reduction services actually rendered on a specific wood-framed or mass-timber building.
The mobile application 153 has access to all services supported in the mobile computing device 137 (e.g. Apple iPhone or iPad) as the case may be. Such services will include the spray technician wearing a head-mounted digital color camera 137C, with a wireless or wired interface to the mobile computing device 137, for capturing live video-footage of each fire-protection process on a specific project, and also verifying and documenting the CFIC liquid spray treatment of each and every completed Class-A fire-protected wood-framed building fabricated in the factory. Such documentation should include capturing and uploading digital images and AV-recordings of certificates of CFIC liquid dip-infusion stamped and verified along the production line involved the fabrication process, as well as spraying CFIC liquid on wood surfaces as well, as the circumstances may require.

Method of Operating a Just-In-Time Prefabricated Class-A Fire-Protected Wood-Framed Building Factory System Supporting Multiple Production Lines for Producing Class-A Fire-Protected Carbon-Quantized Wood-Framed Components for Constructing Prefabricated Class-A Fire-Protected Wood-Framed Buildings
FIG. 74 describes the primary steps involved in carrying out the method of operating a just-in-time prefabricated wood-framed building factory system 130, supporting multiple production lines 131, as illustrated in FIGS. 61 and 62, for producing prefabricated Class-A fire-protected wood-framed building components, as needed to construct pre-fabricated Class-A fire-protected wood-framed buildings ordered online using the mobile application 153 described herein.
As indicated at Block A in FIG. 74, in response to a purchase order (PO) received at the factory system 130 for a customized or specified wood-framed building, the factory system automatically generates a prefabricated wood-framed building project for the order placed by a customer using the mobile application 153 installed and running on mobile computing system 137A, 137B, or through an equivalent website.
As indicated at Block B in FIG. 74, the factory system 130 analyzes the customized or specified wood-framed building into its wood-framed components, and creates bill of materials (BOM) for the wood-building project.
As indicated at Block C in FIG. 74, the system 130 determines the type and quantity of raw wood and/or engineered wood product (EWP) 132 required to make each wood-framed component required by the wood-framed building project.
As indicated at Block D in FIG. 74, the system 130 determines the supply clean fire inhibiting chemical (CFIC) liquid 142 required to dip-coat and treat wood and/or engineered wood product (EWP) for each wood-framed component required by the wood-framed building.
As indicated at Block E in FIG. 74, the system 130 automatically dip-coats the wood and/or the EWPs in a high-speed dipping tank installed along a production line, as shown in the FIGS. 19A, 23A, 27A and 33A, each containing a controlled supply of CFIC liquid for dip-infusion wood pieces at atmospheric pressure, to produce Class-A fire-protected wood required to fabricate Class-A fire-protected wood-framed components for the wood-framed building, specified by the placed purchase order.
As indicated at Block F in FIG. 74, the carbon quantization engine 500 is used to quantize the carbon secured in the fire-protected wood-framed components required to construct the ordered wood-framed building.
As indicated at Block G in FIG. 74, a code symbol 138A and RFID tag 138B with certifications and verifications 300D and fire protected carbon units (FPCUs) are mounted on a substrate 138C, as shown in FIG. 68C, which is permanently applied to each produced Class-A fire-protected wood-framed/mass-timber component 132A, 132B, 132C, 132D, 132E produced in the factory for the ordered prefabricated wood-framed or mass-timber building.
As indicated at Block H in FIG. 71, each symbol coded/RFID-tagged Class-A fire-protected wood-framed component 132A, 132B, 132C, 132D, 132E is loaded into an ISO-shipping container 136 assigned to the fire-protected carbon-quantized wood-framed building project.
As indicated at Block H in FIG. 74, the ISO-shipping container 136 is delivered to the location where the fire-protected carbon-quantized wood-framed building is to be constructed. Thereafter, construction of the Class-A fire-protected prefabricated wood-framed building begins at the construction site.
In the event the purchaser of the prefabricated wood-framed building requested on-site application of Class-A fire-protection spray treatment, using CFIC liquid (i.e. Hartindo AF31), a professional fire-protection spray treatment (provider) team will use the system network 100 shown in FIG. 55 to apply, certify, verify and document the Class-A fire protection liquid spray process as described in detail above, in synchronism with the prefabricated builder's schedule. As each predesignated section of the wood-framed building is constructed by assembling pre-fabricated Class-A fire-protected wood-framed building components (e.g. wall panels, floor and roof truss panels, stair components, etc.), the spray technicians will spray treat all exposed interior surface of the completed section of the wood-framed building, and certify, verify and document the spray treatment using the mobile application 153 using mobile computing devices 137 and services supported by the system network 100. Once completed, the prefabricated Class-A fire-protected wood-framed building will be double-protected with Class-A fire-protection, providing the building owner with many benefits, including potentially lower property insurance premiums, in view of the fact that significant risk of total destruction by fire has been significantly reduced or otherwise minimized.
By virtue of the JIT factory system 130, it is now possible to produce, as needed, a custom or pre-specified wood-framed building made from Class-A fire-protected wood-framed building components, thereby minimizing inventory and cost of manufacture, and improving the quality and precision of prefabricated Class-A fire-protected prefabricated wood-framed buildings.

An example of SWS equipment 133 that might be used for this purpose could be the Prime Smart Count Bluetooth/RFID Speedy Counting Scale System, commercially available from Prime Scales, Inc., or many other digital weigh scale systems well known in the art.
FIG. 76A illustrates the weighing of CFIC liquid totes 181′ at chemical factory 180 before shipment and recording tote weight in supply chain management database 113A. FIG. 76B illustrates the weighing CFIC liquid totes 181′ at the factory 130A (130B, 130C), and recording tote weight in supply chain management database 113A before acceptance. The method of supply chain management and control will be described below.
FIGS. 77A, 77B and 77C describes the high level steps carried out in a method of maintaining the chain of custody, quality control, tracking and inventory replenishment when producing and supplying clean fire inhibiting chemical (CFIC) material (e.g. liquid or dry powder) in locked totes 181′ shipped from the chemical factory 130A, 130B and 130C to a network of Class-A fire-protected wood producing factory systems 130A (130B, 130C), as illustrated in FIG. 76.
As indicated at Block A in FIG. 77A, a supply chain manager 186 shown in FIG. 76 issues a purchase order (PO) to a chemical factory system 180 for the production and delivery of clean fire inhibiting chemical (CFIC) liquid to a specified factory system 130A, as shown in FIGS. 76B and 77A, for producing Class-A fire-protected lumber using the CFIC liquid dipping and infusion process of the present invention, as illustrated in FIG. 79A. Notably, the supply chain manager 186 can be a human being, or an automated or artificially-intelligent (AI) computer system programmed to determined the amount of CFIC liquid required to treat a quantity of raw lumber, and produce a quantity of Class-A fire protected lumber in accordance with the principles of the present invention.
As indicated at Block B in FIG. 77A, the purchase order is received and processed, and the quantity of CFIC liquid is determined required to fulfill the purchase order.
As indicated at Block C in FIG. 77A, one or more CFIC powder or liquid containing totes 181′ are procured to fulfill the purchase order, either by (i) blending CFIC powder and/or liquid, and filling up and CFIC totes 181′, and/or (ii) removing one or more CFIC totes 181′ from inventory maintained in a warehouse 187 as shown in FIG. 76. In the illustrative embodiment, each CFIC tote 181′ has a combination lock mechanism that prevents others without the lock code from accessing the chemical contents of the CFIC tote 181′.
As indicated at Block D in FIG. 77A, barcoded/RFID-tagged shipping labels 200 are generated for the shipment. In the illustrative embodiment, the shipping labels 200 include the purchase order identification number contained in the purchase order. In the illustrative embodiment, each shipping label 200 includes the purchase order identification number contained in the purchase order. Preferably, the barcode and RFID-tag code structures will encode the purchase order identification number in one way or other, or be linked to this identification number using suitable techniques.
As indicated at Block E in FIG. 77A, the barcoded/RFID-tagged shipping labels 200 are applied on the CFIC totes 181′, and will include a barcode symbol component 200A and an RFID-tag component 200B. In some embodiments, one or more of these identification components will be used for auto-identification of each CFIC tote 181′ used on the system of the present invention.
In general, various kinds of barcode symbol and RFID-tag technologies can be used to realize the barcoded/RFID-tagged shipping labels 200 comprising barcode 200A and RFID-tag 200B. Various RFID-labels, RFID-tags and barcode labels are available from Zebra Technologies, Inc., Holtsville, NY.

Virtual Fire-Protection Job-Site Inspection Process of the Present Invention Using Virtual Reality (VR) and Augmented Reality (AR) Technologies to Support Virtual Inspection of an Actual Fire-Protected Job-Site Based on a 3D Virtual Model of the Actual Fire-Protected Wood-Framed Building Under Construction
FIGS. 83A, 83B and 83C describe the primary steps performed during the virtual fire-protection job-site inspection process of the present invention, using virtual reality (VR) and augmented reality (AR) technologies to support virtual inspection of an actual fire-protected job-site based on a 3D virtual model of the actual fire-protected wood-framed building under construction.
Referring to FIGS. 83A through 83C, a novel VR/AR-based virtual fire-protection job-site inspection process is described. The process enables the reviewing of collected data during and after completion of a fire protection spray service carried out in accordance with the principles of the present invention, so that fire risk engineers and others can determine that the specific wood-framed building has been actually and properly fire-protected by the spray process of the present invention.
As indicated at Block A in FIG. 83A, the first step of the method involves building a 3D virtual model of wood-framed building being constructed on a job site located at specific GPS coordinates, that is to be fire-protected using the job-site fire protection spray service of the present invention.
As indicated at Block B in FIG. 83A, a complete set of barcoded/RFID-tagged inspection checkpoints 300 are identified and specified for each completed wood framed building section, and these checkpoints 300 linked to the specific job-site fire-protection spray service process, are adapted for posting at specific completed sections of the wood-framed building using an appropriate mounting substrate 300C.
As indicated at Block C in FIG. 83A, the complete set of barcoded/RFID-tagged inspection checkpoint labels 300 are printed out for mounting on plastic templates or substrates 300C with integrated RFID tags 300B.
As indicated at Block D in FIG. 83A, the barcoded/RFID-tagged inspection checkpoint labels 300A/300B are mounted on plastic templates 300C with integrated UHF-Class RFID tags 300B available from Zebra Technologies, Inc., and the section and project numbers are then programmed into each embedded UHF-Class RFID tag 300B using an RFID tag writer 117A well known in the art. A suitable RFID tag reader/writer would the 13.56 MHz Pistol Grip Handle RFID Reader/Writer made and sold by GAO RFID, Inc., or Honeywell 70 Series UHF-Class of RFID Hand-Held Readers.
As indicated at Block E in FIG. 83A, after each wood-framed building section has been completed, the construction job site supervisor/manager will request job site spray service for the completed section of the wood-framed building. At this stage, the proper barcoded/RFID-tagged inspection checkpoint 300 is permanently posted on the completed wood-framed building section, as illustrated in FIG. 62A. At this stage, the request will be translated into a purchase order to ship one or more CFIC totes from inventory storage to the building construction job site, that is, if there is not a sufficient quantity of CFIC liquid on the job site to spray the barcoded/RFID-tagged completed section of the wood-framed building.
As indicated at Block F in FIG. 83B, before spraying the completed wood-framed building section, the spray technician (i) reads the barcoded/RFID-tagged inspection checkpoint on the section, (ii) reads the barcoded label on the CFIC tote to be used to fire-protect spray the completed building section, and (iii) capture GPS coordinates of the spray technician, and then upload the read barcode data and GPS data to the Central Network Database 113A.
As indicated at Block G in FIG. 83B, the spray technician sprays the CFIC liquid on all exposed wood in the interior of the completed wood building section.
As indicated at Block H in FIG. 83B, the spray technician confirms spraying the completed wood building section by signing the Certificate of Spraying printed on the barcoded/RFID-tagged inspection checkpoint 300, and the spray manager/supervisor verifies that the spray technician sprayed the completed wood building section on the certified date/time by signing the Verification of Spraying printed below the Certificate of Spraying.
As indicated at Block I in FIG. 83B, the spray technician and/or spray manager or other party captures on-site visual data of the spraying event performed by the technician, and uploads the captured visual data of the event, including certificates, verifications, and photos and videos, to the Central Network Database 113A.
As indicated at Block J in FIG. 83B, upon completing each section of the wood-framed building, repeat Steps F, G, H and I above, so as to capture and upload, captured visual data of the event including certificates, verifications, and photos and videos, to the Central Network Database 113A.
As indicated at Block K in FIG. 83B, when all sections of the wood-framed building are completed and sprayed with job site fire protection, then the spray project manager issues a Certificate of Completion of fire-protection of all exposed interior wood used in the wood-framed building.
As indicated at Block L in FIG. 83C, uploaded data captured at each inspection checkpoint is linked to a corresponding virtual inspection checkpoint 300 represented in the 3D virtual model of the wood-framed building.
As indicated at Block M in FIG. 83C, authorized stakeholders are enabled to walk through the 3D virtual model of the wood-framed building, using a client computing system deployed on the system network. During the virtual walk-though, the authorized stakeholder can access and review the uploaded data linked to each AR-based virtual inspection checkpoint 300 augmented with real job-site collected data certifying and verifying that the fire protection spray process was properly applied to all exposed interior wood surfaces in the completed wood-framed building section, including displaying quantized carbon figures for each fire-protected section. The stakeholder can also make comments and leave notes at these AR-based virtual checkpoints 300.
As indicated at Block N in FIG. 83C, notes and comments made during step M are compiled to allow the spray manager address any concerns or issues raised by the stakeholder.
As indicated at Block O in FIG. 83C, fire risk engineers and insurance underwriters are enabled to assess the data collected and uploaded to the virtual checkpoints 300 in the 3D virtual model, and then issue (i) a reduction in the fire risk profile of the fire-protected wood framed building, and (ii) a corresponding reduction in fire insurance on the fire-protected wood-framed building during and/or after building construction.
By virtue of the present invention, fire and construction insurance underwriters, as well as fire risk engineers, will be provided unprecedented access to data, documents and documentation, in a virtual building inspection environment, whereby (i) the individuals who actually performed the professional services on specific dates and times, confirm and verify that such professional services were performed on the wood-framed building, and (ii) all of these actual confirmations and verifications by such professionals are captured, uploaded and stored as GPS, data and time stamped documents in a central network database system 113A, under a single project associated with a specific fire-protection services contract between two parties, upon which fire, construction and property insurance underwriters will have the confidence to grant insurance premium reductions (i.e. discounts or rewards) for confirmed and verified fire-risk reduction services actually rendered on a specific wood-framed or mass-timber building.
Construction Workers can Use the Mobile Application of the Present Invention on Construction Job Sites to Instantly Message Local Fire and/or Police Departments
As described hereinabove, the mobile application of the present invention 120 provides many different services to the stakeholders. A few additional services relate to empower construction workers on the job site to instantly message (i) the local fire department of fire and/or smoke observed in the building in which they are working, and/or (ii) the local police department of suspicious activity in or around the building in which the construction workers are working.
Preferably, a number of different quick send messaging formats will be displayed on the GUI screen so the worker can quickly select and send with minimal screen clicks/taps, automatically sending the email, text/SMS to the local fire department and/or police station, calling for immediate attention, in the event of an emergency, without searching for phone numbers or the like. The message will automatically include the GPS coordinates of the message sender, and the job-site location indexed thereto, so that there is no guessing or ambiguity regarding from where the message originated. At the local fire department receiving the worker's message, the fire department personnel will automatically access fire risk profile records associated with the location of the building under construction, from where the message appears to have been originated, informing the fire department of what might be expected when the arrive at the building fire. The local fire department will be automatically notified by the system that the wood-framed building under construction has been either completely or partially fire-protected using the professional fire-protection spray service of the present invention, and access to spraying confirmations, verifications and other captured records (i.e. data, documents and documentation) on the way to the construction site.
FIG. 84A shows the mobile application 120 configured for use by job site construction workers enabling them to instantly select and send specific-kinds of emergency messages to the local fire department with a single screen click, using services supported by the system network. As shown in the exemplary GUI screen of FIG. 84A, the user (i.e. construction worker) is provided with a menu of restructured exemplary messages from the Fire Dept. Messages menu: (i) all workers exiting building now; (ii) workers are trapped on the upper level; (iii) fire on the second floor, both ends of building; and (iv) building has M-Fire™ Protection, come in and save it. These reconstructed messages allow instant messaging with minimal screen-clicks, and are very useful in emergency situations when job site construction fires break out.
FIG. 84B shows the mobile application 120 configured for use by job site construction workers enabling them to instantly select and send specific emergency messages to the local police department with a single screen click, using services supported by the system network. As shown in the exemplary GUI screen of FIG. 84B, the user (i.e. construction worker) is provided with a menu of restructured exemplary messages from the Police Dept. Messages menu: (i) suspicious arson outside building; (ii) arson ignited fire in building & on bike; and (iv) arson ignited fire in building and running away. These reconstructed messages allow instant messaging with minimal screen-clicks, and are very useful in emergency situations when job site construction fires break out.
Many illustrative embodiments of the present invention have been provided, showing the application of environmentally-safe aqueous-based free-radical chemical reaction breaking chemical liquid to the surface structure of diverse kinds of wood materials products used in building construction to provide Class-A and other levels of fire-protection to wood-framed and mass-timber buildings, and by significantly reducing the fire risk profiles of such wood building structures, logically entitle the building owners (and builders during construction) lower fire insurance premiums. Great efforts have been taken and disclosed herein to provide advanced technological measures to capture data on the construction site and document that in fact these wood-framed buildings have been professional treated with clean fire inhibiting chemicals (CFIC) to deliver the specified fire protection that has been contractually procured between the parties involved. Enterprise-level carried grade cloud-based wireless networks have been disclosed for practicing the various fire prevention and documentation inventions taught in great technical detail herein.
Using Visible Fire-Protection Badges on Wood-Framed Fire-Protected Buildings to Inform Firefighters, First Responders and Police Personal that any Particular Home, Residential or Commercial Building has Received Fire-Protection Treatment
Another object of the present invention is to provide a visible and electromagnetically-detectable way for firefighters, first responders and police personal to instantly ascertain and confirm that any particular home, residential or commercial building has received fire-protection treatment in accordance with the principles of the present invention. As illustrated in FIG. 85, such methods may include mounting visible fire-protection badges (e.g. barcoded/RFID-tagged badges) 310 on the outside of each fire-protected building (e.g. over or about the exterior of each doorway frame) so as to signal to any firefighter approaching the building that it has been fire-protected in a certain way, providing assurance and knowledge how best to fight any fire that may have broken out in the building. The barcoded/RFID-tagged fire-protection indication badge 310 can be easy read by firemen and other first responders using their human vision, or using mobile electro-optical and/or electromagnetic scanners and readers to instantly ascertain that the house is fire-protected with an extended fire rating, as documented in an accessible central network database, and/or Internet-based registry, and/or encoded within the barcoded/RFID-tagged fire-protection indication badge itself, as is possible using suitable barcode symbology and/or RFID code structures known in the art.
Various methods and apparatus have been disclosed herein for registering each wood-framed and mass timber building within an Internet-based central network database after the building has been fire-protected using the job-site spray service of the present invention, so that mobile computing devices running the application of the present invention can be used to instantly access and determine, the fire risk treatment and profile of any specific building registered in the web-based database system. This way, using the address of the building recorded in a database and presented on an electronic map, or reading a physical barcoded/RFID-tagged badge 310 mounted on the exterior of the doorway of the any fire-protected building, firefighters, police and first responders can instantly access the fire protection and prevention records associated with the wood-framed building, and make informed decisions on how best to respond, rescue and fight any given fire within the building. Insurance companies underwriting fire insurance policies on fire-protected and badged wood-framed buildings, mass-timber timber CLT buildings, or even hybrid material buildings, can instantly access such fire risk prevention records maintained on the building in the central network base, which may be accessed by any and every insurance company on the planet, once provided with the appropriate application programming interface (API) well known in the networked database arts.
Virtual Reality (VR) Enabled Walkthrough Inspection of Prefabricated Fire-Protected Wood-Framed Building Components (e.g. Panels) Supported on a Client Computing System Deployed in the Enterprise System of the Present Invention
FIG. 86 shows a set of prefabricated fire-protected carbon-quantized wood-framed building panels manufactured in a prefabricated building panel factory, as illustrated in FIGS. 68A through 79L, and described hereinabove.
FIG. 87 illustrates a VR-enabled walkthrough inspection of prefabricated fire-protected carbon-quantized wood-framed building components (e.g. panels) supported on a client computing system deployed in the enterprise system of the present invention. As shown, one of the AR-Inspection Checkpoint Icons 138′ is expanded to the show a digital image of the actual signed inspection checkpoint 138 captured and uploaded to the network database 148A during the factory-applied fire-protection confirmation and verification process.
FIG. 88 shows a VR-enabled walk-through inspection of the factory-applied fire-protection process of the present invention applied to a prefabricated wood-framed building manufactured in a factory. A sequence of AR-Inspection Checkpoint Icons (ICP #1 through ICP #9) 138′ displayed along the VR-enabled walk-through, containing signed certification and verification documents and data collected from the factory, for display, review and downloading during the inspection walk-through.
FIGS. 89A and 89B describes the remote factory-applied fire-protection inspection process of the present invention. This process, similar to the process illustrated in FIGS. 82A, 82B and 82C, uses VR and AR technologies to support virtual inspection of a factory-applied fire-protected wood-building components, based on a 3D virtual model of the fire-protected wood-framed building components manufactured in the factory.
Referring to FIGS. 89A and 89B, a novel VR/AR-based virtual fire-protection inspection process is described. The process enables the reviewing of collected data during and after completion of a factory-applied fire protection service carried out in accordance with the principles of the present invention, so that fire risk engineers and others can determine that the specific prefabricated wood-framed building or components 132 have been actually and properly fire-protected by the CFIC liquid infusion process of the present invention.
As indicated at Block A in FIG. 89A, the first step of the method involves building a 3D virtual model of prefabricated wood-framed building 132 being constructed within a factory system 130 located at specific GPS coordinates, that is to be fire-protected using the factory-applied fire protection process of the present invention.
As indicated at Block B in FIG. 89A, a complete set of barcoded/RFID-tagged inspection checkpoints 138 are identified and specified for each completed wood framed building section, and these barcoded/RFID-tagged inspection checkpoints 138 linked to the specific factory-applied fire-protection process, are adapted for posting on wood-framed building components using an appropriate mounting substrate 138C.
As indicated at Block C in FIG. 89A, the complete set of barcoded/RFID-tagged inspection checkpoint labels 138 are printed out for mounting on plastic templates or substrates 138C with integrated barcode symbols 138A and UHF-Class RFID tags 138B.
As indicated at Block D in FIG. 89A, the barcoded/RFID-tagged inspection checkpoint labels 138A/138B are mounted on plastic templates 138C with integrated UHF-Class RFID tags 138B available from Zebra Technologies, Inc., and the section and project numbers are then programmed into each embedded UHF-Class RFID tag 138B using an RFID tag writer 117A well known in the art. A suitable RFID tag reader/writer would the 13.56 MHz Pistol Grip Handle RFID Reader/Writer made and sold by GAO RFID, Inc., or Honeywell 70 Series UHF-Class of RFID Hand-Held Readers.
As indicated at Block E in FIG. 89A, after a prefabricated wood-framed building component 132 has been completed and fire-protected, then the barcoded/RFID-tagged inspection checkpoint 138 is posted on the prefabricated wood-framed building component 132, showing carbon-quantization (FPCU) figures, and it is signed by the technician applying fire-protection, and verified by the supervisor of the fire protection technician.
As indicated at Block F in FIG. 89B, before fire-protecting the prefabricated wood-framed building section 132, the fire-protection technician (i) reads the barcoded/RFID-tagged inspection checkpoint 138 on the prefabricated fire-protected building component 132, (ii) reads the barcoded label on the CFIC tote used to fire-protect the wood-framed building component 132, and (iii) capture GPS coordinates of the fire-protected technician, and then upload the read barcode data and GPS data to the network database 148A.
As indicated at Block G in FIG. 89B, the uploaded data captured at each inspection checkpoint 138 is linked to a corresponding AR-virtual inspection checkpoint 138′ represented in the 3D virtual model of the prefabricated wood-framed building component 132.
As indicated at Block H in FIG. 89B, authorized stakeholders then walk through the 3D virtual model of the fire-protected wood-framed building component 132′, and (i) reviewing and viewing the uploaded data linked to each AR-based virtual inspection checkpoint 138′ including carbon-quantization figures, and (ii) making comments and leaving notes at these AR-based virtual checkpoints.
As indicated at Block I in FIG. 89B, fire risk engineers and insurance underwriters are enabled to assess the data collected and uploaded to the virtual checkpoints 138 in the 3D virtual model, and then issue (i) a reduction in the fire risk profile of the fire-protected carbon-quantized wood framed building component 132, and (ii) a corresponding reduction in fire insurance on the fire-protected wood-framed building 132 during and/or after building construction.
Modifications to the Present Invention which Readily Come to Mind
The illustrative embodiments disclose the use of clean fire inhibiting chemicals (CFIC) from Hartindo Chemicatama Industri, particular Hartindo AAF21 and AAF31 and Dectan chemical, for applying and forming CFIC-coatings to the surface of wood, lumber, and timber, and other engineering wood products. However, it is understood that alternative CFIC liquids will be known and available to those with ordinary skill in the art to practice the various methods of Class-A fire-protection according to the principles of the present invention.
Also, in many applications, there will be a desire to protect the Class-A fire protection provided to wood products from UV radiation, moisture, and mold and rot, and applying UV/moisture/mold protective polymer-based coatings over the Class-A fire protection. This can be achieved as taught herein for Class-A fire-protected OSB panels, wherein the UV/moisture/mold protective coating can serve this purpose. Many alternative methods of UV/moisture/mold protection can be practiced to provide protection to the Class-A fire protection using CFIC liquid materials.
These and other variations and modifications will come to mind in view of the present invention disclosure.
While the on-site applied spray of CFIC liquid was shown for newly constructed prefabricated Class-A fire-protected wood-framed buildings, it is understood that this method of Class-A fire-protection treatment also can be practiced on older buildings having: (i) open unfinished attic spaces disposed above roof-trusses with open, unfinished ceiling surfaces, wall and floor surfaces, where bare interior wood surfaces made from raw OSB panels are exposed and at high-risk to fire; and (ii) open unfinished basement spaces, where wall panels are open, exposed and at high-risk to fire. In such environments, the Class-A fire-protection spray-treatment method of the present invention can be practiced with excellent results.
While several modifications to the illustrative embodiments have been described above, it is understood that various other modifications to the illustrative embodiment of the present invention will readily occur to persons with ordinary skill in the art. All such modifications and variations are deemed to be within the scope and spirit of the present invention as defined by the accompanying Claims to Invention.
