The present invention relates to reinforcement devices, systems and methods useful for constructing and reinforcing a structure. Specifically, one embodiment of the reinforcement device is an adjustable foundation system for use as reinforcement structural columns, posts and/or supports for a structure, particularly for use in new construction of pole barns and other buildings. The present invention further includes a reinforcement device useful for securing to and stabilizing existing structural posts of a building such as wooden support columns of a post frame or pole buildings. The present invention also relates to a system and method for raising the height of an existing building or structure using a reinforcement device, thereby providing more useful interior space for accommodating large pieces of equipment and/or for providing more storage capacity.
It is, of course, generally known to construct a structure, such as a shed, barn, garage, etc., using wooden posts set into a series of holes dug in the ground to define a perimeter and create the initial frame for the structure. In the case of pole barns, the structural or framing posts are buried in the ground, and often surrounded by dirt, gravel or concrete. However, long-term contact of wooden posts with the ground can lead to post rot of these wood pilings, resulting in potential structural failure, often prematurely. Additionally, many older structures, such as older barns, with wood columns embedded into the ground subject to decay, rotting, and insect infestation, which can affect the overall integrity of the structure. However, it is often desirable to repair older, wood frame structures to maintain their integrity for various reasons including costs, convenience and history.
Improvements continue to be made to provide longevity, durability and strength to post frame buildings. The traditional method of repair requires that large holes be excavated within the building next to and/or around each post. A new post is then installed next to the existing post and the posts are bolted together. With this traditional method, there is typically no new foundation installed and no additional uplift protection. Opening up large holes including breaking and tearing out concrete flooring around the existing columns is invasive, labor intensive and costly. Additionally, most traditional repairs will take several days to a week to complete, and can be expensive.
For decades, post frame buildings were built all across America that were designed to store equipment and machinery that was much smaller in stature than what is in use on today's modern farms. As a result, many of these otherwise useful buildings are being removed to make room for new buildings with higher interior clearances to accommodate today's larger farm machinery. However, razing a structure and building a new one can be time-consuming and expensive. Additionally, many older structures have value, not only historically but may also have sentimental value to the owner. Therefore, a need exists for refurbishing existing buildings by extending existing wood columns to increase the interior space clearance, thereby providing the interior height and space needed for today's modern farm equipment.
Additionally, there exists a need for options to the traditional wood post construction of foundations for new buildings. Replacing traditional wood foundations with easy to use columns made of material able to withstand rot, decay and insect damage that traditional wooden posts are susceptible to, or expand and contract due to freezing and thawing, results in a structure more durable and well-protected against destructive natural forces than the average post frame building foundation. Because each column can be stabilized and adjusted both vertically and horizontally the integrated grade board bracket allows the wall post to interlock. This allows the entire foundation system to be stabilized and minor, if any, post movement occurs when backfilling the excavated holes with concrete, resulting in a solid, precise foundation system. Moreover, the lack of pre-cast concrete posts eliminates the possibility of blow outs that can compromise the integrity of the foundation's concrete.
A need, therefore, exists for improved devices, systems and methods for reinforcing a structure. Specifically, a need exists for improved devices, systems and methods for reinforcing and stabilizing failing structural elements including structural and framing posts quickly and easily.
A need further exists for improved devices, systems and methods for providing a reinforcement device for use in constructing an improved foundation for a structure wherein the foundation is resistant to the elements, rot and decay and insect infestation.
Additionally, a need exists for improved devices, systems and methods for constructing a foundation using preassembled columns, and the pre-drilled holes which make for simple attachment to boards and planks used in the construction of a foundation for a structure. This saves time and increases labor efficiency.
A need further exists for improved devices, systems and methods for constructing a foundation utilizing columns much lighter than traditional wooden posts or precast concrete columns, making lifting safer and easier for the worker and reducing the need for heavy machinery to assist in transportation and installation.
Further, a need exists for improved devices, systems and methods for providing a reinforcement device useful in raising the height of an existing structure.
Moreover, a need exists for improved devices, systems and methods for reinforcing wooden posts or columns of an existing structure using fewer tools and workers to install the device.
A need further exists for improved devices, systems and methods for providing an efficient and time-saving structurally sound repair to failing columns supporting a building.
Additionally, a need exists for improved devices, systems and methods for constructing a new structure while further protecting it from future decay and potential insect infestation.
A need further exists for improved devices, systems and methods reinforcing and stabilizing a structure utilizing a multi-sided sleeve device for surrounding and reinforcing an existing structural wooden post.
A need further exists for improved devices, systems and methods for stabilizing a structure and providing additional uplift and lateral strength to increase the height of an existing structure thereby increasing the useful interior space of the structure. Often minor height loss is due to sagging from the breakdown of wood columns and settlement.
Additionally, a need exists for repairing and or straightening sagging walls, and providing improved structural integrity to an existing structure so it can better withstand damage from storms, including potential wind damage.
Moreover a need exists for improved devices and systems adaptable for reinforcing a structural element, such as a post for a pole building, have a variety of shapes and sizes.
Further, a need exists for improved devices, systems and methods for a structurally sound repair of existing structural columns at a fraction of the cost to replace existing structural elements or even an entire structure.

Specifically, the present disclosure relates to foundation systems, reinforcement devices, systems and methods for replacing traditional wood and/or precast concrete posts traditionally utilized in constructing or repairing existing post frame foundation components. The present disclosure provides a height adjustable foundation column for use in constructing a foundation for new construction. The height adjustable foundation column assembly is ideally constructed from corrosion resistant materials.
In one exemplary embodiment, the present disclosure relates to a reinforcement device for constructing and supporting a foundation for a structure, the device comprising a column body having a top and a bottom, a bracket secured to the top of the column body, a height adjustment mechanism positioned above and passing through the bracket and within an interior space of the column body extending from top to bottom, the adjustment mechanism capable of vertically moving the column body and bracket between any desired height, and, a stabilizer pad secured to an end of the height adjustment mechanism opposing the top of the column body.

In yet another embodiment, the present disclosure relates to a method for creating a foundation for a structure. The method includes the steps of outlining a perimeter of a structure through the excavation of a plurality of holes, providing a height adjustable column assembly comprising, a column body having a top and a bottom, a bracket secured to the top of the column body, a height adjustment mechanism extending above and downward through the bracket within an interior space of the column body, the height adjustment mechanism capable of vertically moving the column body and bracket between any desired height; and, a stabilizer pad secured to an end of the height adjustment mechanism opposite the top of the column body, positioning each height adjustable column assembly within each hole forming the perimeter, wherein the bracket is above ground level and the stabilizer pad is positioned at the bottom of the hole, adjusting each height adjustable column assembly through the height adjustment mechanism to an acceptable level position; and, disposing at least one board on each of the brackets, forming an initial foundation for the structure.
In another exemplary embodiment, the present disclosure relates to a reinforcement device useful for securing to and stabilizing existing structural posts of a building such as wooden support columns of a post frame or pole buildings. The reinforcement device has a multi-sided corrugated structure, which is adaptable for engagement with structural posts having a variety of shapes and sizes. Additionally, the present disclosure relates to a system and method for increasing the height of an existing structure, due to sagging from a breakdown of wood columns and settlement, or increasing the height of the entire structure, thereby increasing the useable interior clearance space to accommodate large pieces of equipment.
To this end, in an embodiment of the present invention, a device for reinforcing an existing structural element of a building is provided. The device comprises a multi-sided sleeve having an elongated body comprising a longitudinal center section integrally connected along opposing edges to a pair of opposing longitudinal legs or panels having a length the same as the center section. Each leg is connected at an angle or bend to the center section, wherein the angle can vary depending on the size of the structural element.
In an embodiment, a reinforcement device is provided for use in reinforcing an existing structural column. The reinforcement device comprises a multi-sided structure, having a center longitudinal section flanked on either side and integrally connected to a pair of opposing legs, wherein the legs have the same longitudinal length as the center section. Each of the center section and legs further include a raised portion or apex substantially in the middle of the center section and each leg, wherein the raised portions provide an overall corrugated structure to the device and intermittent contact with the column.
In another embodiment of the present invention, a system and method for increasing the height and interior space of an existing structure is provided. The system and method includes the steps of providing an suitable reinforcement device, creating a space around an existing column or post, placing the reinforcement device around the existing column, driving the reinforcement device below grade to the original foundation pad, cutting the existing column and supporting it with the reinforcement device, and lifting the structure to the desired height. Once this is achieved a wood spacer block can be installed between the severed column to direct the load back to the original foundation. Fasteners are installed to adjoin the pieces together.
It is, therefore, an advantage and objective of the present disclosure to provide a reinforcement device, system and method useful for creating a foundation for a structure that is resistant to temperature changes, decay, and insect infestation.
It is, therefore, an advantage and objective of the present disclosure to provide a reinforcement device, system and method for reinforcing and stabilizing existing structural elements of a building including structural and framing posts, quickly and easily.
It is further an advantage and objective of the present disclosure provide an improved reinforcement device, system and method for stabilizing a structure and providing reinforcement to existing foundation columns and uplift strength to increase the height of an existing structure thereby increasing the useful interior space of the structure or to lift to correct any sagging resulting from failing wood columns.
Additional features and advantages of the present invention are described in, and will be apparent from, the detailed description of the presently preferred embodiments and from the drawings.
The drawing figures depict one or more implementations in accord with the present concepts, by way of example only, not by way of limitations. In the figures, like reference numerals refer to the same or similar elements.
The present disclosure relates to devices, systems and methods for constructing a foundation and replacing the traditional wood and/or precast concrete columns used for supporting a structure, such as a post-frame building. Specifically, the present disclosure relates to improved reinforcement devices, systems and methods useful in the construction of solid, corrosion-resistant foundations for new buildings, including pole or post-frame buildings. The present disclosure also relates to another embodiment of improved reinforcement devices, systems and methods useful for reinforcing and stabilizing existing structural posts of a building, such as existing wooden columns of a post frame or pole buildings. Additionally, the present disclosure relates to a system and method for utilizing a reinforcement device for increasing the height of an existing structure, thereby increasing the useful interior space of a structure to accommodate larger pieces of equipment and machinery and/or to provide additional storage capacity.
Now referring to the figures, wherein like numerals refer to like parts,
Creating a foundation for a structure, particularly a post-frame or pole barn structure 500, that is resistant to changing weather conditions, rot or decay, and insect-infestation, is vital for the long-term survival of the structure. Additionally, having options away from traditional wood and precast concrete as foundation supports is desirable to meet many of these requirements, and potentially reduce labor and equipment requirements and associated costs. As shown in
The height adjustable column assembly 100 includes a column body 102 having a top 104 and a bottom 106, a bracket 120, 128 at the top of the column body and a height adjustment mechanism 130. As shown in
As shown in
The column body 102 is further strengthened and stabilized by at least one reinforcement anchor 114, which horizontally spans the interior space 102a inside the perimeter of the cage. The reinforcement anchor 114 has generally an X-shape, where each leg 114a of the anchor is rigidly connected, such as by welding, to each of the vertical bars 112. Alternatively, the individual vertical bars 112 of the column body 102 may engage openings 114b in the legs 114a of the anchor, where the bars can be secured, also by welding (
The top 104 of the column body 102 includes a bracket 120, 128. The bracket 120, 128 is designed to receive and secure boards 505, such as the splashboards, grade boards or planks to create the foundation 520 of a building 500, as well as, receive and secure vertical columns 510 used for constructing the walls of the building (
Each upright arm 122 further includes a notch 122c on an outer edge of the upper section 122b of each arm, the notch adapted for receiving, squaring and levelling a string (not shown) useful in determining the overall squareness and level position of a plurality of the column assemblies 100 after placement of the assemblies in respective holes 600 forming the initial perimeter of the building 500 (
As shown in
During construction of a new building, after multiple adjustable column assemblies 100 are placed in each of the respective excavated holes 600 around the proposed perimeter of a building, the side support bracket 126 or brackets of each column assembly 100 engage a board 505, spanning across each of the assemblies (
The third component of height adjustment mechanism 130, the extension rod 135, is generally a smooth rod having a diameter smaller than that of the guide tube 134, that is positioned upward through the bottom 106 of the column body 102 and into the interior of the guide tube 134. The extension rod 135 includes disk-shaped base or foot plate 136 at the bottom of the rod and outside of the column body 102 (
The present height adjustment mechanism 130 is an improvement and an advantage over other mechanisms in standard foundation columns because it provides the option to adjust the adjustable column assembly 100 on a construction site, with precision, while the assembly is in an upright position and already placed within an excavated hole 600. Rough height adjustments can be made prior to installation of the adjustable column assembly 100 into the excavated hole 600; however final, finessed adjustments can be made through the height adjustment mechanism 130, even after wet cement is added to the hole.
Specifically, operation of the present height adjustment mechanism 130 includes the rod 132 passing through the opening 124b in the base 124 of the respective bracket 120, 128 for engagement with the guide tube 134, either through the threaded nut disposed at the top of the guide tube, or through engagement with a threaded interior surface of the guide tube, or, optionally, through non-threaded telescoping engagement between the rod and the guide tube. In one example, using an appropriate tool, such as a screw gun, the rod 132 is rotated downward into the threaded nut 134a of the guide tube 134 until it engages with the extension rod 135, which is positioned upward into the interior space of the guide tube 134. By rotating or pushing the rod 132 downward into the guide tube, and against the extension rod 135, the column assembly 100 can be precisely adjusted, up or down, after placement of the column assembly into the excavated hole 600. Because the guide tube 134 surrounds and protects the rod 132 and extension rod 135 as they connect inside the guide tube from contact with dirt or cement as it is placed within the hole 600 around the column assembly 100, the height adjustment mechanism 130 can adjust the height of the column assembly even after concrete is poured within the hole and while still wet. After the appropriate adjustments are complete, the rod 132 can then either be removed or cut, and a vertical column 510 for construction of a structure can be secured in the bracket 120 using known fasteners (
This height adjustment mechanism 400 functions in a similar manner to adjust the height of the column assembly 100 as the previously-described height adjustment mechanism 130. The first rod 402 passes through an center opening 124b in the base 124, where it enters the interior space of the cylinder 404. With its foot plate 407 at ground level in a hole, the extension rod 406 passes upward through the bottom 106 of the column body 102, and into the interior space of the cylinder, where it meets with the first rod 402. As the first rod 402 rotates and pushes against the extension rod 406, the vertical height of the column assembly 100 can be adjusted up or down to the desired position. As previously described, any number and positioning of reinforcement anchors 114 are provided within the interior 102b of the column body 102.
The present height adjustable column assembly 100 is designed to replace the standard wood, concrete, or combination of both, traditionally used as foundation columns in post-frame or pole barn construction. Constructed from any suitable corrosion-resistant material, such as galvanized steel powder coat or plated materials, the present height adjustable column assembly 100 is light-weight (weighing less than 40 pounds) making easily maneuverable and adjustable for placement within an excavated hole 600, without the need to additional tools or equipment. However, and unlike traditional wooden posts, which can rot and potentially fail, the present column assembly 100 is not susceptible to the elements or insect infestation, nor will the present column assembly expand and contract due to freezing and thawing. Additionally, and unlike traditional precast concrete columns, which are heavy and hard to maneuver once set in place, the light-weight construction of the present column assembly 100 allows for easy placement and adjustability, particularly in view of any one of the height adjustment mechanism assemblies 130, 300, 400 described above. Concrete columns as well can be susceptible to cracking and water damage, which can again jeopardize the overall stability of a structure, and thus are not ideal for use as foundation supports.
Installation of the present height adjustable column assembly 100 in the construction of a post-frame building 500 is significantly easier than traditional foundation systems. Initially, a series of holes 600 are dug using known methods (for example, manually or using an auger) to create the intended perimeter of the building 500. A separate height adjustable column assembly 100 is set, generally by hand by one or two persons, into each hole 600 (
As described, the adjustable column assembly 100 is used to create the foundation for a structure, by acting as a base for attaching grade boards and post frame columns. Although it is common to use wood grade boards for creating the foundation of a structure,
The features and advantages offered by the present height adjustable column assembly 100 mean that installation of the foundation column is quick, yet precise. Each column assembly 100 can be accurately put in place quickly, with a typical installation of an entire foundation for a post-frame structure being completed in a single day. The speed and precision of installation makes the height adjustable column assembly 100 ideal for stub-ahead projects; crews can dig, set the columns and install the splashboard prior to concrete backfill. This is also beneficial to the new building owner because it allows subsurface work (plumbing, electrical, in-floor heat, etc.) to be complete and concrete flooring poured prior to the crew returning to build the building.
In short, the time savings in installation combined with the durability of foundations built using the present adjustable column assembly 100 translate directly into improved safety, costs and labor savings when compared to other traditional foundation methods. The lightweight nature of the present column assembly 100 means the columns can essentially be set in place by hand by one or two persons, reducing or eliminating the need for tools and heavy equipment, making job sites safer and resulting in more efficient crews. Since column heights and overall leveling can be easily adjusted on site, supporting structural wood columns can arrive pre-cut and ready for attachment to the foundation system.
Advantages of the present height adjustable column assembly 100 include that it is invulnerable to the rot, decay and insect damage that traditional wooden posts are susceptible to, nor will the present foundation column expand and contract due to freezing and thawing. The superior strength of the galvanized steel foundation column of the present assembly 100 means that the structural foundation will never twist or warp, allowing foundations that utilize the present device and system to be more durable and well-protected against destructive natural forces than the average post frame building foundation.
As an alternative to new construction of a building, oftentimes there is a need or desire to repair and reinforce existing post-frame structures, specifically the wood foundation columns found in many post-frame structures, barns and other buildings. Repair or reinforcement is preferred in terms of time and costs over complete replacement of wooden columns in many of these structures. Additionally, razing a structure may not be an option if the structure has historical or family value.
As shown in
The reinforcement sleeve 200 has an overall corrugated shape, including a plurality of curved bends 216, folds or parallel and alternating ridges and grooves formed within the side panels 214 and the center section 212. For example, and as shown in
As shown in
The reinforcement sleeve 200 can be constructed from any suitable material, preferably steel, including galvanized steel for strength, longevity and corrosion-resistance. Additionally, the reinforcement sleeve 200 can have any length required for the particular project. For example, a sleeve 200 used for strengthening an existing column or post may be shorter in length than a sleeve that will be used for extending the height of a structure. Once installed into the ground 230 around an existing support column 250, the reinforcement sleeve 200 can be secured to the existing support column, using any manner of fastener including nails, screws, bolts, etc., through fastener holes 220 on the sleeve. The reinforcement sleeve 200 acts to stiffen and reinforce the lower portion of the wooden column 250 against lateral, uplift, and downward pressures. Additionally, straps (not shown) may be used to further fasten the reinforcement sleeve 200 around the column 250 or post.
Installation of the reinforcement sleeve 200 may be completed with a specialty hydraulic driving device, similar to an automatic jack hammer, which mechanically drives the sleeve into the ground around the target column 250. An advantage of using the hydraulic driver is that it reduces the amount of digging required to place the reinforcement device 200 into position. Although a slight amount of digging may be required around the base of the post or column to initially place the reinforcement device 200, the driver secures the reinforcement device below grade using less time and manpower than traditionally required to place a second securing post. It should be understood that in place of the described driver, the reinforcement sleeve can also be installed using any suitable manual tool (i.e., hammer or maul), jack hammer, or another other suitable means for driving the sleeve into the ground.
Wood columns used to construct post frame buildings tend to fail over time due to dry rot and decay caused by microbial activity at the soil surface and just below the surface. This creates a risk of column failure or building damage, which is a real problem for the building owner, and can be very expensive to repair. The present disclosure also includes a system and method for reinforcing a column, post or other supporting structure for a building using the reinforcement device 200.
The system and method for reinforcing and/or stabilizing a column 250 or post includes the steps of initially digging a shallow hole 230 or trench around the base of the target column 250. The reinforcement sleeve 200 is then positioned within the hole 230 and over the existing column 250 from inside the building. Because of the corrugated shape of the reinforcement sleeve 200, the center section 212 and legs or side panels 214 of the sleeve cradle and contact the column at multiple contact points as shown in
Although a reinforcement sleeve 200 is described as an option for reinforcing an existing wooden column, there is an option to use the height adjustable column assembly 100 described above in the repair of a structural column. Specifically, the existing column can be dug out of the ground and removed. The adjustable column assembly 100 would then be positioned in the ground, completely replacing the wooden column. Because the adjustable column assembly is not susceptible to the elements, or insect infestation, it would provide a long-term solution to maintaining the foundation of the existing building.
For decades, post frame buildings were built all across America that were designed to store equipment and machinery that was much smaller than what is in use on today's modern farms. As a result, many of these otherwise useful buildings are being removed to make room for new buildings with higher interior clearances. However, there is often a reason to save and restore existing buildings, including costs, historical value and sentimental value.
The present disclosure includes a system and method for raising the height of an existing structure by up to 36″, thereby increasing the useful interior space. The system and method for raising the height of a structure includes using the present reinforcement sleeve 200. The reinforcement sleeve 200 can have any suitable length, for example up to 12 feet long, which makes the reinforcement sleeve useful for raising an older, shorter building to a newer height. Once the reinforcement sleeve 200 is installed around an existing column 250 as previously described, the existing wood columns can be extended up to 36″, thereby increasing the interior clearance and allowing the height needed for today's modern farm equipment, construction equipment, or just to provide additional interior storage space within an existing structure.
The method of raising an existing structure begins with cutting an existing column will both sides and on the face of the column. The reinforcement sleeve 200 will be driven into the ground (using some form of a driver as described above), leaving a suitable portion of the sleeve above grade. The remaining portion of the column 250 would then be cut separating the column into two pieces. The building or structure would be jacked up or lifted incrementally using known methods and equipment (i.e., jacks), until it reached the desired height. The gap from the lift would be filled with appropriate filler. A vertical fastener, such as a steel strap would be used to fasten and tie all the pieces together, including the sleeve 200, which would also be attached to the column 250. After raising the structure to the desired height, any void left under the existing sidewall would be filled in with appropriate material, for example, a new steel wainscot.
It should be noted that various changes and modifications to the presently preferred embodiments described herein will be apparent to those skilled in the art. Such changes and modifications may be made without departing from the spirit and scope of the present invention and without diminishing its attendant advantages. Further, references throughout the specification to “the invention” are nonlimiting, and it should be noted that claim limitations presented herein are not meant to describe the invention as a whole. Moreover, the invention illustratively disclosed herein suitably may be practiced in the absence of any element which is not specifically disclosed herein.
