This invention advances the joining of standard building materials for manufacturing mass produced, efficient, concrete form barriers. The barrier application herein will also serve in a wide variety of uses other than formwork
The inventor has many years experience in concrete form design as well as, managing general construction.
Formwork must be assembled quickly in a rigid or sub-rigid composition and maintained in a pre-engineered and static fabrication during concrete placement and subsequently dismantled and stockpiled for future multiple uses. While experimenting with various barriers for concrete formwork, it became apparent that the modality of this system, of applying variations of; elements, parameters, and cubic content, offers a new way to build many barriers that those schooled in the art will easily recognize.
The super-ordinate beam members guide the systematic fabrication of barriers without the use of separate nails, screws, or other fastening devices to join the main beam and sub-beam this is particularly attractive in formwork as these beams must be joined and separated repeatedly as the forms are moved from one placement to another.
When produced as scale models, the invention further offers an easy method of displaying the rapid assembly of a formwork barrier as well as the rapid disassembly of the barrier for sales and instructional purposes.
The Facer Beam Barrier System embodies the specifics of numerous classes and subclasses including;
US Class 52 732.2, 737.5, 656.1, 348, 762, 481.1, 729.1
International classifications EO4C 3/30
Systems of prior art teach a framing method of layering that consists of two or more layers of installed components in order to achieve a frame and cover with layers extending well beyond the limits of the load gathering dominant beam member. None of the prior art searched, that uses removable standard building materials, displays a single plane, self-contained, load gathering barrier system in which only 3 basic components can provide a continuous straight, or radius barrier, without any added parts and pieces. In fact every example of prior art indicates that conventional form systems are double the depth of the Facer Beam Barrier System in order to achieve the same amount of beam loading capacity.
None of the prior art searched by the inventor, reviewed, or found on the market displays a method similar to the ratiocinative, interlocking Facer Beam Barrier System of U.S. Pat. No. 6,662,520, of which this application is a continuation in part offering an alternate method of producing the super-ordinate beam.
The inventor conducted an informal prior art search and also had an international PCT search report done. International search report application number PCT/US03/02891 is applicable in part.
The International Search Report cited four previous patents as having relevant subject matter. They include;
And the inventor also refers to U.S. Pat. No. 3,452,960 granted to G. F. Bowden on 1 Jul. 1969
Many other patented formwork systems and framing systems were searched in order to prove this barrier system patent-able.
Non-Obvious Improvements and Applications
Most of the prior art applications that have structural similarity to the Facer Beam Barrier System are found in formwork applications, and a review of the following examples display the differences.
Bowden teaches a method of extending transverse sub-members in repetition with the ability to overlap and stabilize a plurality of collateral vertical wales, he does not teach a method of ease and efficiency for extending his materials collaterally in a vertical direction. Bowdens system is restricted to formwork applications and does not display the parameters desired for housing the sheathing within the main load-gathering member and does not display a method of attaching sub-members such as the material interface of the invention herein.
Bowdens system does not complete formwork application and removal with the ease, versatility, and competence of the facer beam system claimed herein. The multi-functional breech and chamber beam, the highlight of this new invention, goes well beyond Bowdens load-gathering beam.
Chapman and Bowden employ a combinatory logic that requires three different beam types in support of the plywood. Bowden and Chapman both lack the ability to remove plywood modules, or to remove subordinate beams with ease.
Menchetti fails to recognize a method of overlapping subordinate beam members and he does not reveal a method of incorporating the main member or super-ordinate beam as a facer beam. Menchetti's art does not address issues related to formwork such as self-contained; staging brackets, beam connections, lifting eyes and self contained fastening systems (his fastening system is applied to each facer panel and is not a function of the main beam member).
The patent search revealed no form systems that have subordinate beams fall entirely inside the parameters of super-ordinate beams. All form systems to date offer layers upon layers of structural members designed to support and align less structurally competent members. The patent search revealed no barrier systems or formwork systems that employ the face of beam in concert with the facer panel to achieve a continuous flat plane that may be extend horizontally or vertically with 2 standard building components plus the super-ordinate beam of this invention.
Improvement over prior art lies in many obvious and non-obvious areas. The most significant improvement is the time saved in the integration of three main building components for a sub-rigid barrier.
Further economic advantages offer the construction contractor a super-ordinate beam designed to interlock standard structural supplies, such as nominal 2×6 lumber beams and 4×8 sheets of plywood, these supplies being those most commonly used for all sorts of construction barriers. With the super-ordinate facer beams a contractor can quickly assemble and disassemble any type of temporary or permanent barrier or enclosure he may need, from formwork, to the site office and warehouse buildings, to street barricades.
The inventor has referenced the following industry manuals, plus other support issues, in the course of designing this invention, and they include:

Objectives
Concrete may be the second most traded commodity in the world and every cubic meter of concrete placed requires a mold or form to hold it in place. The formwork industry today is, dominated by a few extremely large companies, based on rentals and returns. These large companies control the market and they shape the market to require their rental products and most of their rental products do not integrate with the competition.
The main objective of the Facer Beam System (species “B”) from U.S. Pat. No. 6,662,520 is to offer a concrete formwork system that eliminates the product catalog that is full of unnecessary parts and pieces and offer a super-ordinate, breech and chamber, facer beam that contains all the appurtenances needed to complete a concrete form installation and subsequent removal.
Every one of the appurtenances mentioned, in the description, are a separate part of the systems offered today. When all these parts are functionally self-contained a great, industry wide, savings is available and escalating labor costs are brought back to a minimum.
Secondary objectives lie in the versatility of the breech and chamber beam and its ability to compete in any barrier composition whether it be for a house, factory, trailer bed, or a toy.
The Facer Beam Barrier System is advancement in barriers, for the purpose of reducing man-hours in barrier installations. When fixed costs reduce variable cost, and when fixed cost is not significantly increased while variable costs are dramatically decreased, an economical advantage for the average consumer results.
This invention goes steps beyond simply reducing labor, as it reduces supervision and planning, by allowing the modular components to dictate their location and function in a tangible result.
Ratiocinative combinatory logic involves producing new standards for beams, beams that are historically offered as steel shapes, which allow loads to sit on their face or on their end. This invention, through reduction in cubic content, allows; deformed steel plates, hot rolled structural steel beams, cold roll-form metal beams, aluminum beams, plywood beams and the like, to be eligible for more functions.
The Facer Beam Barrier System offers a faster way to employ standard materials in the building of formwork for concrete while reducing man-hours in the installation and removal of said formwork through the significant reduction of supernumeraries and the simplicity of the combinatory logic employed.
The following descriptions will further disclose the advances this invention offers.
The objectives, features and advantages of the present invention will be appreciated when read in conjunction with the accompanying drawings, in which:
The description provided herein explains the manufacture, assembly, disassembly and storage of the components of the Facer Beam Barrier System. Its versatile nature in meeting barrier requirements will be obvious to those schooled in the construction and use of barriers. As shown in the drawings like numerals represent like parts throughout the various views and the following description will be clear with reference to the drawing figures and views as numbered in the description.
Box type facer beams 10, as shown, are deformed from steel plates, however said plates may also be, aluminum, plywood or any other structural elements that require fixing together at the corners.
Side webs 10b are machined providing a series of pentagon shaped openings 13 (
The breech portion, calculated and machined marginally larger than the parameters of subordinate beams 14 (
Upon completion of the cramping procedure, subordinate beams 14 are thus cramped and thus interlocked within chamber portions 13 of super-ordinate beams 10
Also subordinate beams 14 systematically overlap one another 14h, 14g (
Sides 14a of beams 14, when cramped within the chamber of opening 13, are ready to support facer panel 15 (
It is important to understand that in form system applications (
Further the lateral spacing of super-ordinate beams 10 is inventively determined by the size of modular facers 15.
The mechanism also requires wedge platforms 19a and 19b (

When point 16e is manipulated down onto wedge platform 19a, spikes 16c are extended beyond beam side-web 10b, further
Device 16 thus offers a self-contained fastening appurtenance that may be retracted by manipulating plate 16 at point 16f onto wedge platform 19b, when retracted in this manner mechanism 16 is arrested in the stored location.
Device 16 thus inventively negates the need for independent fastening devices.
The sub-rigid barrier of
Furthermore shoe 12 (
Shoe 12 is a non-member of the barrier system however shoe 12 is the same size and composition as subordinate beam 14 and therefore plate assembly 21 is dimensioned and deformed to snugly fit over shoe 12.
Slot 21f (
Slot 23a further allows pin 24 to be manipulated back to a retracted position where pin handle 24a (
Face-to-face beams 10 (
Tie 29 is a part of a tie assembly
As shown, pipe 28 is a retainer for bolt 29 and 29 is designed to pass through hole 28a then thread through the novel inner nut 29b and bolt head 29a manipulates bolt 29.
Nut 29b is engineered to fit snugly and structurally within the inner circumference 28b of pipe 28. Bolt 29 extends through the face of beam 10, at hole 11 (
Work platforms 30 (
The staging bracket assembly of arm 31 is shown in working position with a railing arm 34 (
Arm 34 is a safety device that rotates up to stand 90 degrees away from arm 31 in order to support railing members that protect workers from falling off the work platform.
Arm 31 has the capability of releasing and folding down and back alongside arm 34 into storage position (
Arm 31 further comprises a mechanical appurtenance with bolt 35 (
Arm 34 has a wedge, shaped appurtenance 34c (
Slot 34d (
Arm 31 may be tightly wedged alongside arm 34 with the same mechanism that holds arm 31 in working position.
Furthermore bracket arm 31 is fixed and retained to beam 10 by retention pin 32 (
A plate 33 (
When a working platform 30 is not needed arm 31 may slide to the right side of the beam 10 enclosure where end 31h will be free from plate 33 thus allowing arm 31 to rotate at point 31a down within the confines of beam 10 where it is housed along with arm 34 (

Subordinate beams 48 machined with a series elongated penetrations 48b through the flat elongated surface side 48a of beams 48, penetrations 48b may be centered in relation to side 48a and penetrations 48b are generally no wider than one third of the side to side distance across the flat side 48b and penetrations 48b are generally a length that assimilates the face 48b width and penetrations 48b are generally spaced apart a distance that allows frequent availability of penetrations 48b,
The series of penetrations 48b as shown (
Wedges may be manufactured by selecting a rectangular piece of material the same composition as or stronger than the material composition of subordinate beams 48 and the rectangular material is machined to a thickness marginally less than the width of said penetrations, said rectangular material 50 (
Subsequently when wedges 49a and 49b are forced against side-webs 10b, parallel beams 10 are forced to apply compression on facer edges 15c. Therefore when a facer is between beams 10 it may be thus fastened in a flat plan with super-ordinate beam face 10a.
Furthermore when a barrier is formed with three or more lateral super-ordinate beams 10, with two or more facers 15 in place, opposing wedges 49c and 49d may be forcibly inserted at the outer sides of beams 10, at each end of a barrier, thus compressing the entire barrier from side to side, thus providing a solid composition while maintaining a sub-rigid composition.
