Patent Application
20210017764
The present disclosure relates generally to building surface products, for example, panels suitable for forming a building surface. The present disclosure relates more particularly to building surface products having overlapped edges.
Prefabricated panels, for example gypsum wallboards that are commonly referred to as drywall, are often used to construct building surfaces. The wallboards are attached to a supporting structure, such as the joists of a wall frame. Once the wallboards are hung on the supporting structure, the wall is finished using joint compound or another material to create a smooth surface. The wall may then be painted or covered with wall paper.
Gypsum wallboards are advantageous for use as a building surface for various reasons. Such wallboards are incredibly durable, have excellent fire resistance, are easily repaired, and are easy to mount on a supporting structure. Typically, mounting gypsum wallboard panels only requires attaching the wallboards to an underlying supporting structure using mechanical fasteners, such as screws.
While the mounting of gypsum wallboards is relatively easy, most wallboard panels are finished by covering the joints between the panels and the fasteners in order to create a smooth surface. The wallboards are then painted or covered with wall paper to create a pleasing aesthetic. The process of finishing the building surface is time consuming, as each application of joint compound or paint should be dried before the subsequent step can be performed. Moreover, the finishing steps require uncommon skills. Accordingly, the present inventors have determined that a building surface formed of gypsum-based products that are constructed without requiring timely finishing would be attractive to both builders and customers.

As described above, the present inventors have noted that conventional building surfaces formed of gypsum products involve extensive finishing to meet customer expectations. The present inventors have determined that a building surface formed of gypsum-based products that are constructed without requiring timely finishing would be attractive to both builders and customers.
Accordingly, one aspect of the disclosure is an interlocking building surface product including a substantially planar gypsum panel having an upper edge, a lower edge, and two ends. The gypsum panel includes a body comprising a front face, a rear face, and a thickness between the front face and the rear face. An upper interlocking structure is disposed at the upper edge of the gypsum panel and a lower interlocking structure is disposed at the lower edge of the gypsum panel. The upper interlocking structure includes a first upper projection that extends upward from the body of the gypsum panel and has a thickness that is smaller than the thickness of the body. Likewise, the lower interlocking structure includes a first lower projection that extends downward from the body and has a thickness that is smaller than the thickness of the body. The upper interlocking structure and the lower interlocking structure are configured to cooperate with neighboring gypsum panels so as to form a building surface.
Such a building surface product is shown in perspective view in
Gypsum panel 102 also includes an upper interlocking structure 110 disposed at the upper edge 104 thereof. Moreover, a lower interlocking structure 112 is similarly disposed at the lower edge 106 of the gypsum panel 102. Upper interlocking structure 110 and lower interlocking structure 112 are configured to cooperate with neighboring gypsum panels so as to form a building surface. For example, as explained in more detail below, the upper interlocking structure 110 of building surface product 100 may cooperate with the lower interlocking structure of a neighboring building surface product. Likewise, the lower interlocking structure 112 of building surface product 100 may cooperate with the upper interlocking structure of another neighboring building surface product. The terms upper and lower, as used herein, refer to one possible installation configuration of the building surface product on a support frame, and are used for relative directions in such a configuration. However, embodiments of the building surface product can be installed in other configurations, such as configurations in which features described as being on an upper side of the product are disposed on the bottom. Likewise, the building surface product of the disclosure can also be installed vertically, such that features described as upper and lower are disposed on the left and/or right.
As shown in the side view of building surface product 100, in
In certain embodiments of the interlocking building surface product as otherwise described herein, the gypsum panel comprises a reinforced gypsum material.

For example, in building surface product 100, upper interlocking structure 110 includes an upper recess 132, similar to lower recess 130, that is adjacent to first upper projection 122. As shown in
In certain embodiments of the interlocking building surface product as otherwise described herein, the lower interlocking structure includes a second lower projection adjacent the rear face of the body, and wherein the lower recess is in the form of a lower groove disposed between the first lower projection and the second lower projection. An example of such a building surface product is shown in
In certain embodiments of the interlocking building surface product as otherwise described herein, the first upper projection is disposed between the front face and the rear face and forms a tongue configured for insertion into the groove of a neighboring building surface product. For example, building surface product 400, shown in
In certain embodiments of the interlocking building surface product as otherwise described herein, the upper interlocking structure includes a second upper projection, wherein an upper groove is disposed between the first upper projection and the second upper projection, and wherein the upper groove and the lower groove are each configured to receive an insert that cooperates with a corresponding groove of a neighboring building surface product. Such a building surface product is shown in
Each of the upper interlocking structure 510 and lower interlocking structure 512 are configured to receive an insert, such as insert 540, in the respective upper recess 538 and lower recess 530. Accordingly, neighboring building surface products having a configuration similar to that of building surface product 500 connect to one another using the upper interlocking structure and lower interlocking structure via an insert disposed in the adjacent recesses. In some embodiments, the recesses of adjacent building surface products are aligned such that the insert may be a straight plank. In other embodiments, the recesses are offset or have complex shapes, and the insert has a corresponding shape configured to be received in the recesses of two neighboring building surface products. In some embodiments, the upper and lower recesses extend along the entire length of the building surface product, and the insert likewise extends across all or a substantial majority of the building surface product. In other embodiments, the upper and lower recesses are intermittently positioned along the length of the building surface product, and one or more inserts are positioned therein to connect neighboring building surface products.
In certain embodiments of the interlocking building surface product as otherwise described herein, the first lower projection has a chamfered edge. For example, such a building surface product is shown in
In certain embodiments of the interlocking building surface product as otherwise described herein, the first lower projection has a rounded edge. For example, such a building surface product is shown in
In certain embodiments of the interlocking building surface product as otherwise described herein, the upper side of the body has a chamfered edge. For example, building surface product 600 includes an angled surface extending from front face 616 of body 614 toward first upper projection 622 that forms a chamfered edge 644.
In certain embodiments of the interlocking building surface product as otherwise described herein, the upper side of the body has a rounded edge. For example, building surface product 700 includes a convex curved surface extending from front face 716 of body 714 toward first upper projection 722 that forms a rounded edge 744. Similarly, building surface product 800 includes a concave curved surface extending from front face 816 toward first upper projection 822 that forms a rounded edge 844. While building surface product 600 includes chamfered edges 642, 644 toward both the top and bottom of front face 616, building surface product 700 includes convex rounded edges 742, 744 toward both the top and bottom of front face 716, and building surface product 800 includes concave rounded edges 842, 844 toward both the top and bottom of front face 816, in other embodiments, the building surface product may include a chamfered edge combined with a rounded edge, or a concave rounded edge combined with a convex rounded edge. Likewise, in some embodiments, the building surface product includes a straight edge combined with a rounded or chamfered edge. Other combinations and edges are also possible.
In certain embodiments of the interlocking building surface product as otherwise described herein, the ends are perpendicular to the upper edge and the lower edge. For example, building surface product 100, shown in
In certain embodiments of the interlocking building surface product as otherwise described herein, the ends are curved. For example, building surface product 1000, shown in
In certain embodiments of the interlocking building surface product as otherwise described herein, a portion of a first end of the gypsum panel is configured to overlap with a portion of a neighboring building surface product. For example, building surface product 1100, shown in
In certain embodiments of the interlocking building surface product as otherwise described herein, the building product further includes a facing that lines at least a portion of the gypsum panel. In some embodiments, the facing is a paper facing. In other embodiments, the facing includes reinforcing fibers. For example, in some embodiments, the facing includes a fiberglass mat. Further, in some embodiments, the gypsum product of the gypsum panel the building surface product is embedded into the facing.
In certain embodiments of the interlocking building surface product as otherwise described herein, the facing surrounds the gypsum panel along its length. For example, in some embodiments, the facing is formed from two distinct sheets that are wrapped around the gypsum panel. The facing sheets may then be attached to one another to surround the panel. In some embodiments, the facing sheets wrap around the panel along its length. The ends of the panel may then either be left uncovered or the facing sheets may also be folded over the ends.
In certain embodiments of the interlocking building surface product as otherwise described herein, the facing includes a reinforcing sheet disposed at the rear face of the gypsum panel. For example, in some embodiments, the facing includes a robust paper, board, or fiber-reinforced sheet at the rear of the gypsum panel. The reinforcing sheet may provide added strength for attaching the building surface product to a support structure. In some embodiments, the reinforcing sheet is disposed only along the rear face of the gypsum panel. For example, the reinforcing sheet may be used in combination with another facing along the front face of the gypsum panel that has a lower tear strength than the reinforcing sheet. Likewise, in some embodiments, the front face of the gypsum panel may be free of any facing, while the reinforcing sheet is disposed along the rear face of the gypsum panel.
In certain embodiments of the interlocking building surface product as otherwise described herein, a front surface of the building surface product includes a textured surface. For example, in some embodiments, the front surface of the building surface product is sanded or roughened to provide a surface texture to the front face of the building surface product. Further, in some embodiments, a coating of a grainy or heterogeneous coating is applied to the front surface of the building surface product. For example, building surface product 1200, shown in
In certain embodiments of the interlocking building surface product as otherwise described herein, the front face of the body includes grooves along the length of the gypsum panel. For example, building surface product 1300, shown in
In certain embodiments of the interlocking building surface product as otherwise described herein, the building product further includes fastener holes extending through the gypsum panel. For example, building surface product 1300 includes fastener holes 1352 that extend through the first upper projection 1322 of the upper interlocking structure 1310. By placing the fastener holes within a portion of the upper interlocking structure, the fastener holes can be obscured by the first lower projection of a neighboring building surface product that hangs over the first upper projection 1322. The building surface product 1300 also includes fastener holes 1352 through the body of the gypsum panel 1302 within grooves 1350. The fastener holes within the grooves are also obscured by their placement within the grooves, where lighting is reduced. In other embodiments, fastener holes are provided alternatively, or in addition, within the lower interlocking structure, or through the entire thickness of the gypsum panel.
In certain embodiments of the interlocking building surface product as otherwise described herein, the front surface of the building surface product provides acoustical dampening to the building surface product. For example, in some embodiments, the front surface of the building surface product includes baffles, ridges, protrusions or other surface features that enhance sound dampening.
In certain embodiments of the interlocking building surface product as otherwise described herein, a front surface of the building surface product is painted. For example, in some embodiments, the building surface product is painted prior to installation on a support structure, such as in a manufacturing facility. Thus, in some embodiments, the building surface product is painted before any mechanical fasteners are used to attach the building surface product to a support structure, such as wall joists. Indeed, in some embodiments the building surface product is painted and is free of mechanical fasteners extending therethrough.
In certain embodiments of the interlocking building surface product as otherwise described herein, a width from the upper edge to the lower edge is in a range from 3 inches to 4 feet, e.g., from 4 inches to 2 feet, e.g., from 6 inches to 1 foot. A width of the building surface product that is smaller than standard gypsum wallboard products, for example from a few inches up to a foot, can provide an aesthetic that is similar to shiplap. As a result, the joints between the building surface products form part of the aesthetic of the building surface, and do not need to be covered and hidden. This allows surfaces that are made using the building surface products according to the disclosure to be constructed without the need to cover the joints between the building surface products, which can save considerable time and effort.
In certain embodiments of the interlocking building surface product as otherwise described herein, a length from a first end of the gypsum panel to a second end of the gypsum panel is in a range from 1 foot to 20 feet, e.g., from 2 feet to 15 feet, e.g., from 4 feet to 12 feet. In some embodiments, thickness of the gypsum panel is in a range of ¼ inch to 3 inches, e.g., from % inch to 2 inches. Other thicknesses are also possible.
In another aspect, the disclosure provides a method of making an interlocking building surface product according to any of the above-described embodiments. In various embodiments, the method includes forming the substantially planar gypsum panel with the upper edge, the lower edge, the upper interlocking structure disposed at the upper edge, the lower interlocking structure disposed at the lower edge, and the two ends. For example, a method of the disclosure includes forming gypsum panel 102, shown in
In particular, in certain embodiments of the method as otherwise described herein, forming the gypsum panel includes depositing a gypsum slurry over a forming surface and allowing the gypsum slurry to set. An embodiment of a method including this stage is shown in
In certain embodiments of the method as otherwise described herein, the forming surface is configured to form a sheet of gypsum material, and the gypsum panel is cut from the sheet of gypsum material. For example, in
In other embodiments, the forming surface is configured to form the gypsum panel. For example, in some embodiments, the forming surface is part of a mold and the shape of the gypsum panel is formed in mold. Thus, the mold may include boundaries corresponding to the upper edge, the lower edge, the first end and the second end of the gypsum panel. Further, in some embodiments, the mold may include a cover. In other embodiments, the upper surface of the mold is open.
In certain embodiments of the method as otherwise described herein, the upper interlocking structure and the lower interlocking structure are machined into the gypsum panel. For example, portions of the gypsum panel can be cut, routed or otherwise removed in order to form the upper and lower interlocking structures. Such a method is schematically illustrated in
In certain embodiments of the method as otherwise described herein, the forming surface is part of a mold that includes a first portion configured to form the upper interlocking structure and a second portion configured to form the lower interlocking structure. For example, such a method is shown in
In the illustrated embodiment, mold 1664 is open at the ends, so as to form a continuous sheet of the gypsum material that includes the upper interlocking structure 1610 and the lower interlocking structure 1612. The sheet of gypsum material is then cut at intervals to create the gypsum panels. In other embodiments, the mold includes boundaries at the ends and forms a single gypsum panel.
In certain embodiments of the method as otherwise described herein, the method further includes positioning a flexible sheet on the forming surface so as to provide a facing that lines at least a portion of the gypsum panel. In some embodiments, the method further includes positioning a second flexible sheet over the gypsum panel so as to provide the facing that lines another portion of the gypsum panel. For example, in some embodiments, a flexible sheet is positioned on the forming surface and the gypsum slurry is then dispensed over the flexible sheet. As the gypsum slurry takes the form of the panel, the flexible sheet may be wrapped around the sides of the gypsum panel using rollers or guides. A second flexible sheet may cover the opposing side of the gypsum panel. In some embodiments, the flexible sheet is paper. In other embodiments, the flexible sheet is a mat, for example a glass fiber mat. In some embodiments, the flexible sheet includes reinforcing fibers, as described above.
In some embodiments, the method further includes connecting the flexible sheet and the second flexible sheet such that the facing surrounds the gypsum panel. For example, with the flexible sheet wrapped around the sides of the gypsum panel, the flexible sheet may be secured to the second flexible sheet on the opposite side of the panel. When secured on the gypsum panel, the flexible sheet forms a facing around the surface of the panel. The two flexible sheets may be secured to one another, for example, using a combination of folds and adhesive, as will be appreciated by those of ordinary skill in the art.
In certain embodiments of the method as otherwise described herein, the method further includes forming a surface texture on a front surface of the building surface product. In some embodiments, forming the surface texture includes spraying a heterogeneous coating on the front surface of the building surface product. In other embodiments, forming the surface texture includes forming grooves in the front face of the body of the gypsum panel. For example, the formation of the grooves may be carried out by removing material from the gypsum panel, such as by using a CNC machine as shown in
In certain embodiments of the method as otherwise described herein, the method further includes providing fastener holes through the gypsum panel. For example, in some embodiments, fastener holes are drilled through the gypsum panel. The fastener holes promote proper placement of mechanical fasteners to secure the building surface product to a support structure. Further, the fastener holes may also assist in maintaining the structural integrity of the gypsum panel.
In another aspect, the disclosure provides an interlocking building surface system comprising: a plurality of building surface products according to the disclosure secured to a support structure and arranged so as to provide a building surface, wherein the plurality of building surface products includes a first building surface product with an upper interlocking structure coupled to a lower interlocking structure of a second building surface product. Such a system is schematically shown in
In certain embodiments of the interlocking system as otherwise described herein, the first upper projection of the upper interlocking structure of the first building surface product is covered by a first lower projection of the lower interlocking structure of the second building surface product. For example, first lower projection 1725 of lower interlocking structure 1715 of second building surface product 1701 covers first upper projection 1722 of upper interlocking structure 1712 of first building surface product 1701.
In certain embodiments of the interlocking system as otherwise described herein, the system further includes mechanical fasteners securing the plurality of building surface products to the support structure. For example, mechanical fasteners 1796, such as screws, secure the building surface products to the framing elements 1794 of the support structure 1792. In some embodiments, the mechanical fasteners pass through fastener holes in the building surface products, while in other embodiments, the fasteners are forced through the gypsum material.
In certain embodiments of the interlocking system as otherwise described herein, a first group of the mechanical fasteners extend through the first upper projection of the upper interlocking structure of the first building surface product into the support structure, and the first lower projection of the lower interlocking structure of the second building surface product covers the first group of mechanical fasteners. For example, the mechanical fasteners 1796 which attach first building surface product 1700 to support structure 1792 are shown with dotted lines, as they are positioned behind first lower projection 1725 of second building product 1701. Accordingly, because each building surface product overlaps the lower neighboring building surface product, the system may be installed with the mechanical fasteners obscured without the need for any joint compound to cover the mechanical fasteners.
In certain embodiments of the interlocking system as otherwise described herein, each of the building surface products includes a cleat disposed on the rear face of the body, and wherein the support structure includes corresponding cleats adapted to engage the cleats of the building surface products. For example, such a system is shown in
In other embodiments, the building surface products are attached to the support structure using various other methods. For example, in some embodiments, the building surface products are attached to the support structure using an adhesive, such as a pressure sensitive adhesive.
In certain embodiments of the interlocking system as otherwise described herein, a portion of the second building surface product is attached to a portion of the first building surface product using an adhesive. For example, in some embodiments the front surface of the upper projection of the first building surface product is attached to a rear surface of the lower projection of the second building surface product using an adhesive.
In certain embodiments of the interlocking system as otherwise described herein, a rear surface of a portion of the second building surface product is attached to a front surface of a portion of the first building surface product using a fastener. For example, in some embodiments the front surface of the upper projection of the first building surface product is attached to a rear surface of the lower projection of the second building surface product using hook and loop fastener.
In certain embodiments of the interlocking system as otherwise described herein, the plurality of building surface products have different shapes that are arranged in a pattern, and wherein the first building surface product has a first shape and the second building surface product has a second shape. Such as building surface system is shown in
In certain embodiments of the interlocking system as otherwise described herein, a joint between the first building surface product and the second building surface product is free of any joint compound. For example, the upper interlocking structure and the lower interlocking structure may be configured to have an attractive appearance when the building surface products are adjacent, without the need of any joint compound to hide the joints. Accordingly, the building surface system can be constructed without the need to apply or finish any joint compound, which can save considerable effort in preparing the building surface.
In certain embodiments of the interlocking system as otherwise described herein, a front surface of the first building surface product and a front surface of the second building surface product are covered with a layer of paint. In some embodiments, the paint covers the entire exposed front surface of each building surface product. For example, if the building surface is constructed without the use of joint compound, the layer of paint can be applied directly to building surface products from the upper edge to the lower edge and from the first end to the second end.
In certain embodiments of the interlocking system as otherwise described herein, the first building surface product is painted a first color and the second building surface product is painted a second color. Such a building surface system is shown in
In another aspect, the disclosure provides a fastenable building surface product including a substantially planar gypsum panel having a first edge, a second edge, and two ends. The gypsum panel includes a body comprising a front face, a rear face, and a thickness between the front face and the rear face. A first lapping projection extends outward from the body at the second edge and is configured to overlap a portion of a neighboring gypsum panel so as to form a building surface. The building surface product also includes a first press-on connector disposed on the rear face of the body toward the first edge of the gypsum panel. The press-on connector is configured to engage a corresponding second press-on connector.
The phrase “toward the first edge,” refers to the position of the press-on connector being disposed closer to the first edge than the second edge.
Such a building surface product is shown, for example, in
The press-on connector and lapping projection are complementary components that allow the fastenable building surface product to have an interlocking engagement with neighboring building surface products while also being modular. The building surface product can be positioned so that the lapping projection extends behind a portion of a neighboring panel. Subsequently, the first press-on connector can be used to secure the building surface product in place by engaging with a complementary second press-on connector. Further, depending on the construction of the first press-on connector, as explained in more detail below, in some embodiments, the building surface product can be removable and/or re-installable. For example, the building surface product can be removed from a constructed building surface by initially disengaging the first press-on connector and then removing the lapping projection from behind the neighboring panel.
Furthermore, by using a lapping projection and press-on connector, the connections formed between both adjacent building surface products as well as the connections between the building surface products and the support surface are hidden. This allows building surfaces constructed using the building surface products to be completed without the time consuming process of obscuring attachment devices, such as covering mechanical fasteners with joint compound.
While the first edge of building surface product 2100 is shown at the top of the gypsum panel, and the second edge is shown at the bottom, in other embodiments the first and second edges are reversed. Furthermore, in some embodiments, the product can be rotated and installed with either edge at the top. Moreover, in some embodiments, the building surface products are installed vertically.
In certain embodiments of the fastenable building surface product as otherwise described herein, the first press-on connector is a first snap-fit connector and the corresponding second press-on connector is a second snap-fit connector. For example,
The term snap-fit, as used herein, is defined as a connection between components where at least one of the components undergoes a deflection as the components are connected. Accordingly, if the connection is detachable, a corresponding deflection is needed in order to disconnect the assembled components. Such a snap-fit connection can provide a relatively stable attachment without the need for any additional fasteners. The deformation that occurs may be elastic, such that the components return to their original shape after the connection is made or after the components are disconnected. Alternatively, the deformation can be plastic and a permanent connection can be established.
A snap-fit connection, as the term is used herein, encompasses connections where either or both of the components being attached can undergo the deformation. Thus, the first snap-fit connector of the building surface product can undergo a deformation as it is attached to the corresponding second snap-fit connector, or the second snap-fit connector can undergo a deflection as it is attached to the first snap-fit connector.
In other embodiments, the first press-on connector can have another configuration, such as a component of a hook and loop fastener, or another recloseable fastener.
In certain embodiments of the fastenable building surface product as otherwise described herein, the first snap-fit connector includes a connector body and a first flange that extends laterally outward from the connector body and is configured to engage the second snap-fit connector. For example, as shown in
In certain embodiments of the fastenable building surface product as otherwise described herein, the first snap-fit connector includes a second flange that extends from the connector body in an opposite direction of the first flange and is configured to engage the second snap-fit connector. For example, first snap-fit connector 2170 includes a second flange 2175 that extends in an opposite direction from connector body 2172 compared to first flange 2174, specifically, in a downward direction. Like first flange 2174, second flange 2175 is configured to be secured by a second flexible hook 2185 of second snap-fit connector 2180.
Another embodiment of a first snap-fit connector and a second snap-fit connector is shown in
Both first snap-fit connectors 2170 and 2370 have male configurations and second snap-fit connectors 2180 and 2380 have female configurations that receive the first snap-fit connectors. However, in other embodiments, the first snap-fit connector has a female configuration that receives the second snap-fit connector.
The first and second snap-fit connectors may be configured according to different design constraints to have a permanent installation, a re-installable installation, or a removable installation. Various embodiments of such snap-fit connectors are shown in
The removability or permanence of the connection between the first snap-fit connector and second snap-fit connector is dependent upon the angles and edges of the mating components. In the embodiments shown in each of
In contrast, first snap-fit connector 2570 and second snap-fit connector 2580 are configured to allow disconnection of the two components, so that a new building surface product can be installed. However, the inner surfaces of the flanges 2574, 2575 and hooks 2584, 2585 have an appropriate shape to allow disconnection so long as sufficient force is used. In some embodiments, this force is sufficiently high to damage the building surface products, but maintain the function of the second snap-fit connector. Such a configuration allows new building surface products to be installed when one is damaged, but prevents inadvertent or accidental removal upon moderate forces applied to the panels.
Further, first snap-fit connector 2670 and second snap-fit connector 2680 have inner surfaces of the flanges 2674, 2675 and hooks 2584, 2585 to allow repeated removal and reinsertion. This configuration allows maintenance to be on the building surface, or behind the building surface, without the need to replace any components of the building surface itself.
In certain embodiments of the fastenable building surface product as otherwise described herein, the first snap fit connector is in the form of a rail that extends along a length of the building surface product. For example, in some embodiments, the rail extends across at least 50% of the length of the building surface product, e.g., at least 80% of the length of the building surface product, e.g., at least 90% of the length of the building surface product. It should be understood that the length of the building surface product is the longest dimension of the product extending from the first end to the second end. For example, first snap-fit connector 2170, shown in
In certain embodiments of the fastenable building surface product as otherwise described herein, a distance between the first snap-fit connector and the first edge is less than 30% of the width of the gypsum panel body, e.g., less than 20%, e.g., less than 10%. For example, in some embodiments, the first snap-fit connector is disposed in a range of ¼ inch to 3 inches from the first edge of the building surface product.
In certain embodiments of the fastenable building surface product as otherwise described herein, the first snap-fit connector is attached to the gypsum panel using adhesive. In some embodiments, the adhesive is an organic adhesive, such as a curable glue, a single component epoxy, a two component epoxy, a hot-melt thermoplastic, or a polyurethane resin.

The first press-on connector of each building surface product is coupled to at least one of the second press-on connectors. Further, the first edge of the gypsum panel of each building surface product overlaps the first lapping projection of a neighboring building surface product. Such a system is schematically shown in
The second building surface product 2103 is presented as it is being installed.

For example, in some embodiments the second snap-fit connectors are coupled to framing members or a surface of the support structure using screws or nails. In other embodiments, the second snap-fit connectors are secured to the support structure using an adhesive.
In certain embodiments of the fastenable building surface system as otherwise described herein, each of the second snap fit connectors includes a support platform, and wherein each support platform provides a contact surface for a respective first lapping projection of a building surface product. For example, second snap fit connector 2180, as shown in
In certain embodiments of the fastenable building surface system as otherwise described herein, the plurality of building surface products have different shapes that are arranged in a pattern, and wherein the first building surface product has a first shape and the second building surface product has a second shape. A building surface system with such a construction is shown in
In certain embodiments of the fastenable building surface system as otherwise described herein, a joint between the first building surface product and the second building surface product is free of any joint compound. For example, the first and second edges of the building surface products may be configured to have an attractive appearance when the building surface products are adjacent, without the need of any joint compound to hide the joints. Accordingly, the building surface system can be constructed without the need to apply or finish any joint compound, which can save considerable effort in preparing the building surface.
In certain embodiments of the fastenable building surface system as otherwise described herein, a front surface of each of the building surface products is covered with a layer of paint. In some embodiments, a first of the building surface products is painted a first color and a second of the building surface products is painted a second color. A building surface system with such a construction is shown in
In another aspect, the disclosure provides a joint support configured to cover a joint between coplanar wall panels. The joint support includes an elongate support strip with a first end, a second end, a first side edge, a second side edge, an inner surface, and an outer surface. The joint support also includes a facing sheet secured to the outer surface of the support strip. The facing sheet includes a first flap extending laterally beyond the first side edge of the support strip and a second flap extending laterally beyond the second side edge of the support strip. A first adhesive in disposed on an inside surface of the first flap and on an inside surface of the second flap.
A portion of such a joint support is shown in perspective view in
As explained in more detail below, in some embodiments, the joint support is configured to cover the seam between two coplanar wall boards. The term coplanar, as used herein, includes wall boards that are substantially coplanar, for example, including wall panels that are angled no more than 3 degrees from one another in any direction, or no more than 2 degrees, or no more than 1 degree, or no more than 0.5 degrees. The support strip of the joint support is placed directly over the seam and the first and second flaps are respectively attached to the two wall boards.
The use of the joint support has several advantages over conventional wall board joint preparations. For example, in some embodiments, the joint support is installed without a typical tape and embed step, where a joint tape is embedded in joint compound. Skipping the embedding of joint tape within joint compound along the seam can save considerable time. Not only is the process of embedding the joint tape within joint compound time consuming. After the joint has been filled, additional preparation steps typically must wait for the joint compound to dry, which often requires at least 24 hours. Accordingly, using the joint support of the disclosure can substantially reduce both preparation and waiting times.
Further, in certain embodiments, use of the joint support displaces a thick layer of joint compound. Such thick layers of compound are more susceptible to cracking and other damage than a thin layer that might cover the joint support. Accordingly, a wall joint constructed with the joint support of the disclosure may be more robust. Moreover, this added structural integrity of a wall board joint made with the joint support of the disclosure can allow a wider range of uses for completed wall board constructions. For example, wall boards are typically installed and finished after the frame of the wall is in place and stationary. However, by reducing the likelihood of cracking, a section of finished wall that utilizes the joint support of the disclosure can be transported and then installed. Accordingly, prefabricated constructions can be made using finished or partially finished walls that contain standard wall boards with the use of the joint support of the disclosure.
Furthermore, the joint support of the disclosure may provide added safety and performance benefits compared to a typical joint prepared with tape and joint compound. For example, in some embodiments, the joint support provides added fire protection. For example, where the seams of a typical wall board construction might begin to separate during a fire and allow the fire to penetrate through the wall board, the joint support of the disclosure can cover the seam between the wall panels and hinder advancement of the fire through the seam. Similarly, by covering the seam between the wall panels, the joint support of the disclosure can also impeded water intrusion or mold advancement.
In certain embodiments of the joint support as otherwise described herein, at a first position along a length of the support strip, the outer surface extends in a straight line from the first side edge to the second side edge. For example, as shown in the cross-sectional view in
In other embodiments, the joint support is a rolled product, and the support strip is curved along its length in the form of a coil. For example, in some embodiments the support strip and facing sheet are formed of a flexible material that may be rolled along its length. Such a rolled product may be convenient for storage and transport of the joint support. It should be understood that the above description of the shape of the outer surface of the support strip relates to the shape when the support strip is at rest. For example, embodiments where the outer surface is planar may be bent or twisted to have a curve across the width of the support strip, but it should be understood that the outer surface is planar when no loads are applied to the joint support. Likewise, a joint support that is formed as a rolled product may be unrolled into a straight shape when installed, but is rolled when it is at rest.
In certain embodiments of the joint support as otherwise described herein, a cross section of the support strip is uniform in shape along the length of the support strip. For example, support strip 3412 of joint support 3410 has a uniform cross section along its length. In other embodiments, the shape of the support strip varies along the length thereof. For example, in some embodiments, the thickness of the support strip varies along its length. In other embodiments, the width of the support strip varies along its length.
In certain embodiments of the joint support as otherwise described herein, a length of the joint support is at least 4 feet, e.g., at least 6 feet, e.g., at least 8 feet. Further, in some embodiments, the length of the joint support is no more than 20 feet, e.g., no more than 15 feet, e.g., no more than 12 feet. For example, in some embodiments where the joint support is substantially planar, the length of the joint support is limited to no more than 20 feet. In other embodiments, the length of the joint support is longer. For example, in some embodiments a long joint support is used in connection with long wall panels. Further, in some embodiments where the joint support is a rolled product, the joint support is considerably longer, such as 100 feet or more.
In certain embodiments of the joint support as otherwise described herein, a width of the support strip is at least 1 inch, e.g., at least 2 inches, e.g., at least 3 inches. Further, in some embodiments, the width of the support strip is no more than 10 inches, e.g., no more than 8 inches, e.g., no more than 5 inches. For example, in some embodiments the width of the support strip is in a range from 1 inch to 10 inches, e.g., from 2 inches to 8 inches, e.g., from 3 inches to 5 inches.
In certain embodiments of the joint support as otherwise described herein, the first and second flaps of the facing sheet extend at least 1 inch beyond the respective first and second side edges of the support strip, e.g., at least 1.5 inches, e.g., at least 2 inches. Further, in some embodiments, the first and second flaps of the facing sheet extend no more than 6 inches beyond the respective first and second side edges of the support strip, e.g., no more than 5 inches, e.g., no more than 4.5 inches. For example, in some embodiments, the first and second flaps extend in a range of 1 inch to 6 inches from a respective side edge of the support strip, e.g., 1.5 to 5 inches, e.g., 4.5 to 2 inches. In some embodiments the first and second flaps extend an equal distance beyond the respective sides of the support strip. In other embodiments, the first and second flaps are asymmetrical, and one flap extends beyond the respective edge further than the other flap.
In certain embodiments of the joint support as otherwise described herein, a thickness of the support strip is at least 0.02 inches, e.g., at least 0.03 inches, e.g., at least 0.05 inches.
Further, in some embodiments, the thickness of the support strip is no more than 0.25 inches, e.g., no more than 0.15 inches, e.g., no more than 0.1 inches. For example, in some embodiments, the thickness of the support strip is in a range of 0.02 inches to 0.25 inches, e.g., from 0.03 inches to 0.15 inches, e.g., from 0.05 inches to 0.1 inches.
In certain embodiments of the joint support as otherwise described herein, a thickness of the support strip is greatest at a center line that extends along the length of the support strip. For example, in some embodiments, the thickness of the support strip is substantially equal across its width and the thickness is no greater than it is along the center line. In other embodiments, across the width of the support strip the thickness is greater at the center line than it is on either side of the center line. For example, as shown in
In certain embodiments of the joint support as otherwise described herein, the support strip includes a first portion that extends from the center line to the first side edge that tapers to a reduced thickness at the first side edge, and a second portion that extends from the center line to the second side edge that tapers to a reduced thickness at the second side edge. For example, as shown in
In certain embodiments of the joint support as otherwise described herein, a thickness of the support strip at the first side edge is at least 0.005 inches, e.g., at least 0.010 inches, e.g., at least 0.015 inches. For example, in some embodiments, the support strip tapers from the center line to a thin edge that runs along the entire length of the support strip.
In certain embodiments of the joint support as otherwise described herein, the inner surface of the support strip includes a ridge extending along the center line. In some embodiments the ridge is formed as the peak where tapered first and second portions of the support strip meet at the center line. In other embodiments, the ridge is formed by an elongate protrusion that runs along the center line of the support strip. Still, in some embodiments, the ridge is formed by an elongate protrusion disposed on the peak formed where the tapered first and second portions of the support strip meet at the center line. For example, support strip 3412 includes a ridge 3424 that extends along the length of the support strip and is aligned with center line 3420, as shown in
In certain embodiments of the joint support as otherwise described herein, the first adhesive is a pressure sensitive adhesive. Accordingly, in some embodiments, the joint support is configured to be secured to adjacent wall panels by pressing the first and second flaps against the respective wall panels so as to activate the first adhesive and bond the first and second flaps to the wall panels. A variety of pressure sensitive adhesives are suitable for use in the joint supports and methods of the disclosure. Pressure sensitive adhesives are typically based on an elastomeric material, often with a tackifier to provide stickiness. In certain embodiments of the joint support as otherwise described herein, the pressure sensitive adhesive substance is based on an acrylic polymer, e.g., based on one or more acrylate or methacrylate monomers such as acrylic acid, isobutyl acrylate, n-propyl acrylate, n-butyl acrylate, ethyl acrylate, isopropyl acrylate, 2-ethylhexyl acrylate, lauryl acrylate, lauryl methacrylate, isodecyl acrylate, isooctyl acrylate, tridecyl methacrylate, tridecyl acrylate, 2-ethylhexyl methacrylate, and caprolactone acrylate. Other suitable systems can include epoxy resins, polyvinyl acetate, ethylene-vinyl acetate copolymer (e.g., with high vinyl acetate content); butyl rubbers, natural rubbers, nitriles, silicone rubbers, polyurethane, styrene-butadiene rubbers, styrene-isoprene rubbers, styrene block copolymers like styrene-butadiene-styrene (SBS), styrene-ethylene/butylene-styrene (SEBS), styrene-ethylene/propylene (SEP), and styrene-isoprene-styrene (SIS). A variety of tackifiers can be used, depending on the elastomer, e.g., resins (e.g. rosins and their derivates, terpenes and modified terpenes, aliphatic, cycloaliphatic and aromatic resins, hydrogenated hydrocarbon resins, and their mixtures, terpene-phenol resins (especially with ethylene-vinyl acetate adhesives)), novolacs, silicone tackifiers based on so-called “MQ” silicate resins (based on monofunctional trimethylsilane reacted with silicon tetrachloride, especially for silicone rubbers). Many other adhesives and adhesive precursors are known in the art with different modes of operation and may be used as the pressure sensitive adhesive substance. The pressure sensitive adhesive substance can be selected to provide compatibility with the other materials and provide a necessary amount of strength to bond with a building surface.
In certain embodiments of the joint support as otherwise described herein, the first adhesive is water activated. For example, in some embodiments, the first adhesive disposed on the first and second flaps becomes activated when wet with water. Accordingly, during installation, the installer may wet the surface of the first and second flaps and then apply them to the respective wall panels on either side of the joint seam. The adhesive will then form a bond between the flaps and the respective wall panel surfaces.
In certain embodiments of the joint support as otherwise described herein, the facing sheet extends across the width of the outer surface. For example, facing sheet 3430 of joint support 3410 extends across the entire width of the joint support 3410 passing over the entire outer surface 3419 of support strip 3412. Thus, the lateral sides of facing sheet 3430 form the first flap 3432 and second flap 3433. In other embodiments, the facing sheet includes respective sections that form the first flap and second flap. For example, in some embodiments the facing sheet is formed by two strips that are respectively attached near the first and second side edges of the support strip with a gap along the center of the support strip. Further, in some embodiments, the facing sheet extends along the entire length of the support strip, while in other embodiments the facing sheet is formed in sections along the outer surface of the support strip.
In certain embodiments of the joint support as otherwise described herein, the facing sheet is paper. In other embodiments, the facing sheet is formed of another sheet of material, such as a woven or non-woven mat. For example, in some embodiments the facing sheet includes a fiberglass mat or a polymer sheet. Other material sheets are also possible.
In certain embodiments of the joint support as otherwise described herein, the facing sheet is sandable or dissolvable. Accordingly, in some embodiments, the facing sheet of the joint support can be finished in manner similar to a typical joint formed primarily of joint compound.
In certain embodiments of the joint support as otherwise described herein, the joint support further includes a release liner covering the inner surface of the first flap and the inner surface of the second flap. Such release liners serve to prevent unwanted adhesion of the first adhesive with other structures or parts prior to installation of the joint support. For example, before applying the joint support to a building surface, the release liners may be peeled off or otherwise removed from the inside surface of the first flap and the inside surface of the second flap so as to expose the first adhesive disposed on the inside surface of the first flap and the inside surface of the second flap to adhere to the respective wall panels.
In certain embodiments of the joint support as otherwise described herein, the joint support further includes a second adhesive disposed on the inner surface of the support strip. For example, in some embodiments, adhesive is provided across the entire width of the joint support on its inside surface, including the first adhesive on the first and second flaps of the facing sheet and the second adhesive on the inside surface of the support strip. Accordingly, such a joint support may be adhered to the wall panels across its entire width. In other embodiments, the second adhesive is provided on only a portion of the inside surface of the support strip, such as near the first and second edges. In some embodiments, the second adhesive has the same composition as the first adhesive. In other embodiments, the second adhesive has a different composition than the first adhesive. Further, in some embodiments, the inside surface of the support strip is free of any adhesive and the joint support is adhered to the wall panels only using the first and second flaps of the facing sheet.
In certain embodiments of the joint support as otherwise described herein, the facing sheet is secured to the outer surface of the support strip with a third adhesive. For example, in some embodiments, a third adhesive is provided between the support strip and the facing sheet so as to bond the facing sheet to the support strip. In other embodiments the facing sheet and support strip are attached by another means. For example, in some embodiments the facing sheet is bonded to the support strip during a manufacturing process.
In certain embodiments of the joint support as otherwise described herein, the support strip is formed of plastic. For example, the support strip may include at least one of High Density Polyethylene (HDPE), Polyethylene Terephthalate (PET), Acrylonitrile Butadiene Styrene (ABS) copolymer, Acrylonitrile Styrene Acrylate (ASA) copolymer, Polyvinyl Chloride (PVC), PETG, high-impact polystyrene (HIPS), Polycarbonate (PC), Polylactic Acid (PLA), or Polyester. In certain embodiments of the joint support as otherwise described herein, the support strip is reinforced with a fibrous material. For example, in some embodiments, the support strip is reinforced with glass fibers. In other embodiments, the support strip is reinforced with cellulous or other fibers. In other embodiments of the joint support as otherwise described herein, the support strip is formed of metal.

In another aspect, the disclosure provides an overlapping wall panel construction that includes a first wall panel, a second wall panel, and a joint adhesive disposed between the first and second wall panels. The first wall panel has a front face, a rear face, a first edge, a second edge, and a rear projection along the first edge that is coextensive with the rear face and extends past the front face. The rear projection of the first wall panel includes a front-facing attachment surface. The second wall panel also has a front face, a rear face, a first edge, and a second edge. The second wall panel further includes a front projection along the second edge that is coextensive with the front face and extends past the rear face. The front projection of the second wall panel includes a rear-facing attachment surface and overlaps the rear projection of the first wall panel so as to form an overlapping joint and an interface between the front-facing attachment surface of the first wall panel and the rear-facing attachment surface of the front projection of the second wall panel. The joint adhesive is disposed in the interface and bonds the front projection of the second wall panel to the rear projection of the first wall panel.
It should be understood that the front and rear facing attachment surfaces may directly “face” the corresponding directions or may be angled with respect to these directions. For example, the front facing attachment surface of the rear projection at least partially faces the front direction of the wall panels. Likewise, the rear facing attachment surface of the front projection at least partially faces the front direction of the wall panels. In other words, before the wall panels are joined, the front facing attachment surface is viewable from the front of the wall panels and the rear facing attachment surface is viewable from behind the wall panels.
A section of such an overlapping wall panel construction is shown in
In certain embodiments of the overlapping wall panel construction as otherwise described herein, the front-facing attachment surface of the rear projection of the first wall panel extends at an angle to the rear face of the first wall panel, and the rear-facing attachment surface of the front projection of the second wall panel extends at an angle to the front face of the second wall panel. For example, front-facing attachment surface 4166 of rear projection 4165 of the first wall panel 4160 extends at an angle to the rear face 4162 of first wall panel 4160. Likewise, rear-facing attachment surface 4176 of front projection 4175 of second wall panel 4170 extends at an angle to the front face 4171 of second wall panel 4170. Accordingly, the interface between front-facing attachment surface 4166 and rear-facing attachment surface 4176 is disposed at an angel to the plane of the first and second wall panels 4160, 4170. The angle increases the area of both attachment surfaces thereby strengthening the bond between the first and second wall panels 4160, 4170 that is formed by the joint adhesive.
In certain embodiments of the overlapping wall panel construction as otherwise described herein, the rear projection of the first wall panel has the shape of a triangular prism and the front-facing attachment surface extends from the rear face of the first wall panel to the front face of the first wall panel, and the front projection of the second wall panel has the shape of a triangular prism and the rear-facing attachment surface extends from the front face of the second wall panel to the rear face of the second wall panel. For example, rear projection 4165 of first wall panel 4160 has the shape of a triangular prism, as indicated by the triangular shape of the cross-section shown in
In certain embodiments of the overlapping wall panel construction as otherwise described herein, an angle between the front-facing attachment surface of the rear projection and the rear face of the first wall panel is substantially the same as an angle between the rear-facing attachment surface of the front projection and the front face of the second wall panel. The phrase “substantially the same,” as used herein, refers to values that are within 5% of one another. For example, the angle between front-facing attachment surface 4166 and rear face 4162 of first wall panel 4160 is the same as the angle between rear facing attachment surface 4176 and front face 4171 of second wall panel 4170. Accordingly, with the first and second wall panels 4160, 4170 adjacent to one another, front-facing attachment surface 4166 lies parallel to rear-facing attachment surface 4176 so that a thin layer of joint adhesive may bond the two surfaces together.
In certain embodiments of the overlapping wall panel construction as otherwise described herein, the rear projection of the first wall panel is flat and the front projection of the second wall panel is flat. A section of such an overlapping wall panel construction is shown in
In certain embodiments of the overlapping wall panel construction as otherwise described herein, a thickness of the rear projection is substantially the same as a thickness of the front projection. Further, in some embodiments, the thickness of the rear projection of the first wall panel is about half the thickness of the first wall panel and the thickness of the front projection of the second wall panel is about half the thickness of the second wall panel. For example, the thickness of rear projection 4265 of first wall panel 4260 is slightly less than half the thickness of first wall panel 4260. Likewise, the thickness of front projection 4275 of second wall panel 4270 is slightly less than half the thickness of second wall panel 4270. Because the first and second wall panels 4260 and 4270 are the same thickness, the thickness of the rear projection 4265 of first wall panel 4260 is the same as the thickness of front projection 4275 of second wall panel 4270. Accordingly, when front projection 4275 overlaps rear projection 4265, the thickness of the overlapping projections is substantially equal to the thickness of each wall panel 4260, 4270. Thus, the overlapping wall panels may form a smooth surface.
In certain embodiments of the overlapping wall panel construction as otherwise described herein, the rear projection of the first wall panel includes a first base that is coextensive with the rear face of the first wall panel and a first flange that extends forward from the base and forms a first groove between the first flange and a core of the first wall panel. Likewise, the front projection of the second wall panel includes a second base that is coextensive with the front face of the second wall panel and a second flange that extends rearward from the second base and forms a second groove between the second flange and a core of the second wall panel. Further, the first flange of the first wall panel fits in the second groove of the second wall panel and the second flange of the second wall panel fits in the first groove of the first wall panel.
A section of such an overlapping wall panel construction is shown in
