The present invention relates to a composite wall and building system. More specifically, the composite wall and building system comprises a structural beam formed of fiberglass composite, wherein the structural beam includes one or more flanges. The structural beam may be formed in a variety of dimensions and profiles as needed. A plurality of structural beams is used together to form a wall or other parts of the building. An insulator member is configured to abut the structural beam, wherein the insulator member comprises one or more channels sized to receive the one or more flanges.
The construction industry utilizes many different types of wall construction for buildings. Traditionally, buildings are constructed from wood frames and plywood/drywall sheathing that are assembled on site. While these methods have been effective in creating structures, they come with inherent limitations that impact efficiency, structural integrity, and ease of construction. For instance, engineering large spans with wood beams as supports can be challenging, requiring complex load distribution designs. Additionally, on-site construction processes tend to be labor-intensive, time-consuming, and may lead to inconsistencies in quality and precision.
Another type of residential or commercial construction utilizes a composite wall structure which can be quickly constructed into a completely unitary wall structure. Most of these prior composite wall structures have complicated arrangements using large precast panels, leading to challenges in handling and assembly without specialized equipment. Some utilize reinforcing rods that are placed within the space between these panels, necessitating spacer blocks and tie wires to hold them rigidly in position. However, this method of construction has several drawbacks. Handling these larger panels often requires heavy machinery and the assembly process can be complicated.
In view of these developments, there exists a need for a composite wall structure that can be utilized to replace conventional construction. The present invention includes a composite wall structure that incorporates fiberglass composite beams, insulation with cutouts, and magnesium oxide (MgO) boards that streamlines construction processes, enhances structural integrity, and improves energy efficiency. The insulation is also fire-resistant expanded polystyrene (EPS) foam insulation, making these wall structures not only energy-efficient but also significantly enhancing their safety and fire resistance. This insulation further contributes to the overall thermal performance of the system, reducing heat transfer and ensuring a comfortable indoor environment. This wall structure provides improvements over traditional building practices which require the need for plywood sheathing, are labor-intensive on-site assembly, and impose design limitations.
In light of the devices disclosed in the known art, it is submitted that the present invention substantially diverges in design elements and methods from the known art and consequently it is clear that there is a need in the art for an improvement for composite wall and building systems. In this regard the instant invention substantially fulfills these needs.
In view of the foregoing disadvantages inherent in the known types of walls and building systems. The present invention provides a new composite wall and building system for construction and transportation.
It is an objective of the present invention to provide an embodiment of the wall and building system comprising the composite wall and building system comprises a structural beam formed of fiberglass composite, wherein the structural beam includes one or more flanges.

As used herein, “structural beam” includes several variations of beams, such as I-beams, H-beams, W-beams, S-beams, C-beams, L-beams, girders, and the like. Additionally, other terms such as plate, joist, bar, and the like are used interchangeably with structural beam 2000. In one embodiment, the structural beams are constructed through pultrusion thereby forming specific integral elements. These elements are then cut to a desired size as needed. During or prior to the pultrusion, fibers, such as string, glass and/or webbing, are added to the composite to achieve desired structural properties. The composite beams have low conductivity thereby do not transfer heat easily. This assists with the insulation of the walls and does not expand or contract over time. In some embodiments, the edges of the structural beams, such as the H-beam, include ridges or hooks to increase structural strength, as the edges may deform under load. The ridges also assist with the interlocking of the insulation and flanges. Moreover, the ridges and/or hooks provide a mechanical connection when adhesives or sealants are applied during assembly, these hooks provide additional grip and strength to the joint.
In the shown embodiment, the structural beam 2000 comprise a top plate 2100 that forms an upper end of the wall 1500 and a base plate 2200 at the lower end of the wall. Both the top plate and base plate 2100, 2200 run generally horizontal and parallel to each other. An insulator member 3000 is configured to abut the top plate 2100. In the shown embodiment, the top plate 2100 comprises a C-beam with two flanges extending from a central web. The insulator member 3000 comprises a panel having perimeter edges with one or more channels sized to receive the one or more flanges of the structural beams 2000. In this way, the insulator member 3000 is coupled with the beams 2000, and do not require additional fasteners for securement. In some embodiments, fasteners are used in conjunction with the mating of the flanges and channels for securement.
A second structural beam 2000, the I-beam 2300, extends between the top plate 2100 and the base plate 2200. In the shown embodiment, the I-beam 2300 acts as a stud or vertical support member that connects the top plate 2100 and the base plate 2200. This I-beam 2300 acts as a vertical load-bearing member in the wall, supporting the weight of the structure, including the roof and other floors. It helps transfer these loads down to the floor below or to the foundation, ensuring the stability and integrity of the building. The spacing between the I-beam 2300 members is varied depending on several factors, including local regulations. Additionally, the particular structural properties of the I-beam 2300 also define the needed load bearing capacity in any given application.

In one embodiment, the modified beam 6000 is adapted to receive a foam gasket thereagainst. The foam gasket, when placed between the subfloor and the wall, eliminates drafts and enhances the energy efficiency of the structure. In the shown embodiment, the modified beam 6000 includes an upper beam 6100 and a lower beam 6200 used to stiffen the modified beam 6000. The lower beam 6200 may be positioned under a wood plate on the top portion of the wall such that the wood plate rests on the flange 6150 of the upper beam 6100. The wood plate is used to assist in spreading the load of floor joist over the wall system and to make it easier to fasten conventional buildings, for example wood trusses, to the present invention. In one embodiment, the lower beam 6200 is not used should the load and/or span required does not require the additional strength.
In the shown embodiment, the beam 6000 is formed from a shell with support members therein that forms sub-compartments that decreases the weight of the beam 6000. However, in other embodiments, the beam 6000 may be filled or have a different arrangement of support structures. In one embodiment, the beams 6100, 6200 are completely filled and integral and/or monolithic with each other.

In the shown embodiment, a vapor permeable underlayment 7200 forms a layer around an exterior of the joist. A continuous sealant is used at each side of the wood blocking and floor/roof panel to ensure a tight and durable seal, preventing any moisture or air infiltration, and promoting the long-term structural integrity of the building.
Specifically referring to
In the shown embodiment, a drained and ventilated cladding system 9000 is applied to the H-beam 2000 as a protective outer layer. This cladding 9000 is adapted to provide a a safeguard against the elements while also allowing for effective ventilation and drainage. The combination of these features helps to prevent moisture accumulation and promotes the long-term durability of the building's exterior envelope. The wood blocking 8000 utilized in this assembly is fabricated from dimensional lumber, for example 2″×8″ lumber, which is readily aalibale and provides support for the threaded fasteners. This choice of lumber dimensions ensures that there is ample surface area for securely anchoring the screws. In the embodiment described, 3-inch screws are employed for fastening, offering substantial holding power and stability in the joint connections.
The design of this system allows for versatility in construction, accommodating variations in angles and dimensions while maintaining structural integrity. The use of wood blocking in combination with the fiberglass composite joists and H-beams not only facilitates secure fastening but also simplifies the process of adapting to different project requirements. Additionally, the use of drained and ventilated cladding on the H-stud plays a pivotal role in the overall building envelope's performance. This cladding system effectively manages moisture and ventilation, reducing the risk of water damage and allowing the structure to ‘breathe,’ thereby enhancing energy efficiency and prolonging the life of the building.
