This disclosure is related to the field of construction, and more particularly to a reinforcing bracket for use with construction panels, and especially gypsum sheathing.
Structural sheathing materials reinforce building exteriors and enhance overall structural integrity. Various types of structural sheathing are utilized to achieve these goals. Plywood, a widely favored choice, is made of bonded wood veneer layers for strength and dimensional stability. Another common option is oriented strand board (OSB), which is considered cost-effective and robust, and is commonly applied in residential construction. Other options include fiberboard, which is formed from compressed wood fibers, and is often used with other sheathing materials. Insulated sheathing integrates both structural support and insulation, enhancing energy efficiency. Concrete sheathing involves applying a concrete layer for durability and fire resistance. Metal sheathing, featuring steel or aluminum panels, offers modern aesthetics and weather resistance.
Gypsum sheathing is one of the most preferred options because of its inherent properties, which include fire and moisture resistance. Gypsum sheathing is comprised of a core of gypsum enclosed between layers of paper or fiberglass. Modern interior wall panels, known colloquially as “drywall,” has a similar construction. Its moisture-resistant attributes render it suitable for spaces potentially exposed to moisture, like bathrooms, kitchens, and exteriors, and its inherent fire resistance makes it a valuable component in containing and delaying the spread of fire. It also has natural sound insulation capabilities, and is robust, durable, easy to cut and install, and being made from a naturally occurring mineral, recyclable and aligned with sustainable building practices.
One major weakness of gypsum sheathing is shear strength. Shear strength refers to the material's ability to resist forces that cause one part of the material to slide past another along a parallel plane. Shear strength is crucial for withstanding lateral loads such as wind and seismic forces, which can cause a building's walls to shift or tilt. Gypsum sheathing's shear strength is relatively weaker than other components, notably plywood and OSB, which means gypsum sheathing may be more susceptible to failure or deformation under certain lateral load conditions.
Another weakness of gypsum sheathing is accepting screws and fasteners. As is familiar to homeowners, when a screw or fastener is placed into gypsum sheathing and then placed under a load, the fastener tends to migrate, usually downward under the force of gravity, which loosens the connection and may eventually result in the fastener becoming dislodged. If the sheathing is constructed with sufficient rigidity to avoid this, the fastener may break or deform under heavy loads. These problems are especially acute at the edges, where tear-out is commonplace.
The following is a summary of the invention in order to provide a basic understanding of some aspects of the invention. This summary is not intended to identify key or critical elements of the invention or to delineate the scope of the invention. The sole purpose of this section is to present some concepts of the invention in a simplified form as a prelude to the more detailed description that is presented later.

The following detailed description and disclosure illustrates by way of example and not by way of limitation. This description will clearly enable one skilled in the art to make and use the disclosed systems and methods, and describes several embodiments, adaptations, variations, alternatives and uses of the disclosed systems and methods. As various changes could be made in the above constructions without departing from the scope of the disclosures, it is intended that all matter contained in the description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
As can be seen in
Other dimensions and configurations of the load plate are also possible, including fully triangular (without truncated tips), as shown in
The depicted load plate has as receiving bore (105) disposed therethrough from a top to a bottom side. The depicted receiving bore (105) is a round element whose main axis is generally perpendicular to the main plane of the load plate (103). This improves the ease of installing a fastener and assists with ensuring the fastener enters the underlying construction material perpendicularly, which ordinarily provides a strong connection. The depicted receiving bore (105) is disposed near a first corner (110), which, as described below, has a different configuration of anchors (107) from the other corners (112). The size, shape, and position of the receiving bore (105) may vary from embodiment to embodiment based upon, among other things, the type of fastener to be used, which may in turn vary depending on the type of material from which the underlying panel is constructed. In an embodiment, the fastener bore (105) may be threaded or have other features for facilitating a connection with the fastener.
In the depicted embodiment, the reinforcing bracket (101) comprises a plurality of anchors, or legs (107). In the depicted embodiment, the legs (107) have a generally triangular configuration, with the base of the triangle attached or connected to the load plate (103), and an opposing point or tip projecting away from the load plate (103). The depicted legs (107) are disposed approximately perpendicularly from the main plane of the load plate (103), which facilitates installation and minimizes disruption of the internal structure of the sheathing panel, but other angles may be used. By way of example and not limitation, the angle may be slightly acute (i.e., leaning inwardly towards the middle of the bracket (101)) or may be slightly obtuse (i.e., leaning outwardly away from the middle of the bracket (101)). In the depicted embodiment, all of the legs (107) have about the same angle, but in an alternative embodiment, one or more legs may have angles that differ from the rest.
The depicted embodiment comprises four legs (107), with two disposed on adjacent lateral sides of the truncated tip (107) of a first corner (110), and two more each disposed on the truncated tips (107) of the other corners (112). In the depicted embodiment, the first corner (110) also comprises the fastener bore (105), and the multiple leg (107) configuration provided for the first corner (110) provides additional anchoring support for the legs (107) at the area of the load plate (103) where fastening will occur. This provides additional structural strength for receiving and distributing loads, and reduces fastener movement, which could result in disengagement of the fastener and reinforcing bracket (101). The legs (107) may be constructed from a single piece of material, such as sheet metal, which is cut to size with a CNC or metal stamping machine and then bent into final position, or manufacturing techniques known in the art.
As shown in
Although three or four legs are shown in the depicted embodiments, in an alternative embodiment, more or fewer may be used. By way of example and not limitation, the embodiment of
The fastener (111) may be any type of fastener suitable for use in construction, based on the type, size, and composition of the panel and bracket (101), and will generally have a retaining means (113) to anchor the fastener to the reinforcing bracket (101). In the depicted embodiment, the retaining means (113) is a fastener head (113) having a radius larger than that of the fastener bore (105).
The depicted embodiment is generally triangular, with the tips of the triangular shape truncated (109) as shown in the FIGs. As noted, this truncated shape (109) improves ease of installation and spacing, and also eliminates the acute angles that would otherwise appear in the corner, resulting in sharp triangular corners that are more likely to damage the drywall when installed. As shown in the FIGs., the truncated shape also provides a surface for attaching legs (107). The depicted embodiment has a plurality of legs (107) extending downward from the outside perimeter of the load plate (103), generally in locations near the non-right corners and along the non-hypotenuse sides. In the depicted embodiment, the legs (107) and fastener bores (105) are disposed in locations on the load plate (103) corresponding to where the drywall will be attached to underlying framing material. Thus, in alternative embodiments using other shapes, corresponding elements would naturally be disposed in similar locations on the shape.
To install this embodiment, adhesive is optionally applied between a panel (113) and a stud (123) as shown in
In some embodiments, a mending plate (201) may be used to further secure the seams between adjacent panels (113). A non-limiting, exemplary embodiment of one such mending plate (201) is shown in
In an embodiment, the bracket (101) and/or mending plate (201) may be installed using an impact or punch-down tool. An embodiment of such a tool is depicted in
In an embodiment, adhesive may be applied using a specialized tool, an embodiment of which is depicted in
Throughout this disclosure, geometric terms may be used to characterize, among other things, sizes, shapes, dimensions, angles, distances, and relationships. These terms may be used with qualifiers such as “generally,” “about,” and “approximately.” One of ordinary skill in the art will understand that, in the context of this disclosure, these terms are used to describe a recognizable attempt to conform a device or component to the qualified term. By way of example and not limitation, components described as being “generally coplanar” will be recognized by one of ordinary skill in the art to not be actually coplanar in a strict geometric sense because a “plane” is a purely geometric construct that does not actually exist and no component is truly “planer,” nor are two components ever truly coplanar. Variations from geometric descriptions are unavoidable due to, among other things, manufacturing tolerances resulting in shape variations, defects, imperfections, non-uniform thermal expansion, natural wear, minor variations that are nevertheless recognizable as the qualified term, and other deformations. One of ordinary skill in the art will understand how to apply geometric terms, whether or not qualified by relative terms such as “generally,” “about,” and “approximately,” to describe a reasonable range of variations from the literal geometric term in view of these and other considerations appropriate to the context. Additionally, the use of the conjunctive and disjunctive should not necessarily be construed as limiting, and the conjunctive may include the disjunctive, and vice versa.
While the invention has been disclosed in conjunction with a description of certain embodiments, including those that are currently believed to be the preferred embodiments, the detailed description is intended to be illustrative and should not be understood to limit the scope of the present disclosure. As would be understood by one of ordinary skill in the art, embodiments other than those described in detail herein are encompassed by the present invention. Modifications and variations of the described embodiments may be made without departing from the spirit and scope of the invention.
