Description

TITLE OF THE INVENTION
WALL ATTACHMENT CLIP, WALL PANEL SYSTEM, AND
SYSTEM AND METHOD FOR SUPPORTING WALL PANELS
FIELD OF THE INVENTION
[0001] The present invention relates generally to the field of construction. More particularly, the present invention relates to a clip for attaching and supporting wall panels to a building (such as for an exterior building envelope), a wall panel system, and systems and methods for supporting wall panels.
BACKGROUND OF THE INVENTION

[0002] An important consideration in building envelope design and construction is the air and water barrier(s) located behind the exterior facade of the building, as well as the connection of the façade over the air and water barrier(s). Traditional building envelope design (and modifications thereof) requires multi-pass installation, in which multiple separate components are sequentially installed on top of one another to achieve the thermal and moisture protection for the building interior. This typically requires a separate trade group to apply/attach each component, adding to the complication, cost, reliability and overall time needed to construct a building. Additionally, attachment of the exterior façade to the air and water barrier(s) compromises the barrier.

[0003] Figure 1 shows a traditional, multi-component wall construction. As shown in Fig. 1, a barrier panel element 20 is attached to the outer surface of the framing studs 10 and batt insulation 15 is located in the stud cavity. A building wrap 30 is applied (typically sprayed) about the barrier panel element 20, and then the exterior façade 40 is attached by extending an anchor (such as a screw, nail, support bracket, etc.) through the wrap 30 and barrier panel element 20 and into the studs 10. This is referred to as a "triple-pass"
system, in which a first trade group typically applies/installs the barrier panel element (pass 1), a second trade group applies the wrap (pass 2), and a third trade group installs the façade (pass 3). Because the exterior façade anchor extends through the wrap and barrier panel element, the air, water, vapor and thermal barrier(s) of this design is compromised. This creates an increased concern when an anchor for the exterior façade inadvertently misses a stud when it is installed in pass 3, as a hole is created in the barrier(s) that is not filled (at least in part) by the anchor (as is the case when an anchor extends into the stud).

[0004] Adoption of new building codes (such as ASHRAE 90.1 ¨2007) has required increased energy performance requirements for building envelopes, which are not met by the traditional multi-component wall construction shown in Fig. 1. As a result, several alternative modifications of the traditional construction have been proposed and utilized to meet the newer code requirements. A first such alternative is shown in Fig. 2.
As shown in Fig. 2, a barrier panel element 20 is attached to the outer surface of the framing studs 10. A building wrap 30 is applied about the barrier panel element 20, and then an insulation panel 15 is applied over the building wrap 30. Finally, the exterior façade 40 is attached by extending an anchor (such as a screw, nail, support bracket 50, etc.) through the insulation panel 15, wrap 30 and barrier panel element 20 and into the studs 10. This also is referred to as a "triple-pass" system, in which a first trade group typically applies/installs the barrier panel element (pass 1), a second trade group applies the wrap (pass 2), and a third trade group installs the insulation panel and facade (pass 3).
Because the exterior façade anchor extends through the insulation panel, wrap and barrier panel element, the air, water, vapor and thermal barrier(s) of this design is still compromised. This too creates an increased concern when an anchor for the exterior façade inadvertently misses a stud when it is installed in pass 3, as a hole is created in the barrier(s) that is not filled (at least in part) by the anchor (as is the case when an anchor extends into the stud).

[0005] A second alternative to the traditional multi-component wall construction design that has been proposed to meet new code requirements is shown in Fig.
3. As shown in Fig. 3, a barrier (may include insulation functionality as well) panel element 20 is attached to the outer surface of the framing studs 10, and a spray insulation 15 is applied in the stud cavity. A building wrap 30 is applied about the barrier panel element 20, and then the exterior facade 40 is attached by extending an anchor (such as a screw, nail, support bracket, etc.) through wrap 30 and barrier panel element 20 and into the studs 10. This also is referred to as a "triple-pass" system, in which a first trade group typically applies/installs the barrier panel element (pass 1), a second trade group applies the wrap (pass 2), and a third trade group installs the facade (pass 3). Because the exterior façade anchor extends through the wrap and barrier panel element, the air, water, vapor and thermal barrier(s) of this design also is compromised. This again creates an increased concern when an anchor for the exterior façade inadvertently misses a stud when it is installed in pass 3, as a hole is created in the barrier(s) that is not filled (at least in part) by the anchor (as is the case when an anchor extends into the stud).

[0006] In an attempt to overcome one or more of the problems identified with respect to the multi-pass designs of the prior art, several "single pass" systems have been developed. Examples of such systems are shown and described in U.S. patent

7,748,181 (the '181 Patent), and in Exhibits B, C and D to U.S. provisional application number 61/509,109 filed on July 19, 2011, which depict the Invelope/Metalwrap systems by Centria. Referring to Figs. 7 and 9 of the '181 Patent, a first single pass system includes barrier panels 106a and 106b that are interconnected together via tongue and groove type connections. The barrier panels are attached to the framing of the building and provide air, water, vapor and thermal barrier(s) for the building structure, as well as structural support for an exterior façade system. As is shown in Fig. 7, barrier panel 106b is attached to the stud using clip 144 and screw 146. Clip 144 includes downturned central flange portion 148 which penetrates into a foam portion of the top of panel 106b.
The screw 146 extends through the main body portion 150 of clip 144, through panel 106b and into the stud. The lower end of panel 106a is held into position via the tongue and groove connection with panel 106b, and the upper end of 106a is attached to the stud using a clip and screw in the same manner described with respect to panel 106b. As is shown in Fig. 9 of the '181 Patent, a z-shaped subframe 160 is attached to the panels 106 (preferably at their horizontal joint 124) by extending screw 162 through multiple layers of steel 164-168 of the panels 106. The exterior facade panels are then attached to the z-shaped subframe via screws 172. This system is considered a single pass system in that the barrier panels and façade are typically installed by a single trade group.
While this system overcomes many of the problems associated with multi-pass designs, the attachment of the subframe to support the façade panels directly to the barrier panels limits the structural support available for the façade, and also potentially exposes the foam core of the barrier panels to moisture through the holes created by the screws.
Therefore, it would be beneficial to provide a system and method that allows façade panels to be supported directly by the framing of the building, and/or that does not unnecessarily expose the interior of the barrier panel to additional moisture.
[0007] Referring to Exhibits B, C and D of U.S. provisional patent application number 61/509,109, other single pass systems are shown. The system of Exhibit B is similar to that of the '181 patent, with the façade panels supported directly to the barrier panels.
The system of Exhibit C shows a clip that extends out from the barrier panels to provide horizontal support to a façade such as a brick wall. The façade of Exhibit C
is supported vertically by its own structure, not by the clip or the framing of the building. The system of Exhibit D includes a zee girt attached through the barrier panels and into the stud of the building. The zee girt provides support for panels to be attached vertically.
Nevertheless, the zee girt does not allow for panels to be attached horizontally as they would be to a traditional stud wall. Moreover, the zee girt system requires shims to result in proper panel alignment. Therefore, it would be beneficial to provide a system and method that allows façade panels to be supported vertically directly by the framing of the building in a horizontal manner, and/or that does not unnecessarily expose the interior of the barrier panel to additional moisture.
SUMMARY OF THE INVETION

[0008] Objects of the present inventive concept include, but are not necessarily limited to, a clip for attaching and supporting wall panels to a building (such as for an exterior building envelope), a wall panel system, and systems and methods for supporting wall panels. The system and method of the instant invention allows façade panels to be supported vertically directly by the framing of the building horizontally. In addition, the system and method of the instant invention allows façade panels to be supported without unnecessarily exposing the interior of a barrier panel to additional moisture.

[0009] The system and method of the instant invention include components manufactured in a manner similar to those of the '181 and/or of Exhibits B, C
and D. In particular, in one embodiment, the system includes a barrier panel manufactured essentially identical to those shown in Exhibits B, C and D. Nevertheless, it will be appreciated that the instant invention may be utilized in connection with other components now known or hereinafter discovered.

[0010] The system includes a clip that includes a downturned central flange portion that penetrates into a foam portion at the top of an insulated steel sandwich panel (i.e.
foam sandwiched between sheets of steel). A screw extends through the main body portion of the clip through pre-drilled holes in the panel, through the outer and inner metal sheets and sandwiched foam of the panel and into the stud. The lower end of the panel is held into position via the tongue and groove connection with an adjoining panel directly below the panel, and the upper end of the adjoining panel is attached to the stud using a clip and screw in the same manner described above. The clip further includes an extension portion that extends backward from the main body portion and a face portion extending generally perpendicular from the extension portion. The extension portion extends outward of the exterior surface of the panel such that a hat subgirt can be attached to the face portion of the clip via a screw that extends into a preferably pre-drilled hole in the face portion. A façade assembly is then mounted to the subgirt. The clip of the instant invention allows the panel to be attached to the stud of the exterior of the building, and provides a support for façade panels directly anchored in the studs of the building, without compromising the barrier(s) provided by the panel.

[0011] In a preferred embodiment, the clip of the instant invention is made of 14 gauge galvanized steel. Nevertheless, it will be appreciated that other suitable materials may be utilized and will be apparent to those of ordinary skill in the art.

[0012] The foregoing and other objects are intended to be illustrative of the invention and are not meant in a limiting sense.

DETAIILED DESCRIPTION

[0020] As required, a detailed embodiment of the present invention is disclosed herein; however, it is to be understood that the disclosed embodiment is merely exemplary of the principles of the invention, which may be embodied in various forms.
Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present invention in virtually any appropriately detailed structure.

[0021] As shown in Figs. 4 and 5, an embodiment of a clip 100 and of a system of the instant invention utilizing clip 100 is provided. The clip 100 is used for attaching and supporting a wall panel to a building structure. The clip 100 includes a main body portion 102. Located at opposing ends of the main body portion 102, the clip 100 includes a first extension or flange portion 104 and a second extension portion 106. The first extension portion 104 and the second extension portion 106 both extend outward away from the main body portion 102 in opposite directions, with both being substantially tangential to the main body portion 102. At the end of the second extension portion 106, the end opposite the main body portion 102, is located a face portion 108. The face portion 108 extends outward and away from the second extension portion 106 such that it is substantially parallel with the main body portion 102, yet offset by the length of the second extension portion 106.

[0022] In the embodiment shown in Fig. 4, the first extension or flange portion 104 is used to pierce an edge 134 of a vapor barrier panel 130, such as the tongue-and-groove feature shown and described in the vapor barrier panel system of the '181 patent and/or Exhibits B, C and D of U.S. provisional patent application number 61/509,109.
The clip 100 is secured to a building framing 109 with an anchor 107 through the main body portion 102. The vapor barrier 130 is not compromised because the anchor 107 and clip 104 penetrate the panel 130a at an edge 134a that is sealed or covered by the edge 134b an adjacent vapor barrier panel 130b.

[0023] The face portion 108 is used to affix an exterior façade 160 to the exterior of the building. With the exterior façade 160 affixed to the face portion 108 of the clip 100, the exterior façade 160 is structurally supported by the building frame 109 without compromising the vapor barrier 130.

[0024] In some embodiments, the main body portion 102 includes one or more pre-drilled hole(s) 103. In an embodiment with pre-drilled holes 103 in the main body portion 102, the clip 100 is anchored to the building framing 109 through one or more of the pre-drilled hole(s) 103.

[0025] In some embodiments, the face portion 108 includes one or more pre-drilled hole(s) 103. In an embodiment with pre-drilled holes 103 in the face portion 108, the exterior façade 160 is affixed to the clip 100 through the one or more pre-drilled hole(s) 103 in the face portion 108.

[0026] In some embodiments, the first extension portion 104 includes one or more tooth 105 sized and shaped to penetrate a portion of foam insulation that is exposed in a vapor barrier panel 130 along one of the edges 134. In some embodiments, the clip 100 is a single-piece, unibody apparatus. In some embodiments, the clip 100 is made out of 14 gauge galvanized steel.

[0027] As used throughout this specification, the term "substantially tangential"
includes any angle between 80 and 100 degrees. As used throughout this specification, the term "substantially parallel" includes any two planes wherein the smallest angle between the two planes is 15 degrees or less. For example:

[0028] In some embodiments, the first extension portion 104 is substantially tangential to the main body portion 102, but is slightly turned down, such that the angle between the main body portion 102 and the first extension portion 104 is slightly less than a 90 degree angle, or about 85 degrees. In some embodiments, the second extension portion 106 is substantially tangential to the main body portion 102, but is slightly turned down, such that the angle between the main body portion 102 and the second extension portion 106 is slightly greater than a90 degree angle, or about 95 degrees. In an embodiment where the angle between the first extension portion 104 and the main body portion 102 is about 85 degrees and the angle between the second extension portion 106 and the main body portion 102 is about 95 degrees, the first extension portion 104 is substantially parallel to the second extension portion 106 even though they vary from being perfectly parallel by about 10 degrees.

[0029] Figure 4 shows one embodiment of a multiple piece horizontal support bracket for façade panels. As shown in Fig. 4, a system for attaching and supporting a wall panel to a building structure is provided. The system does not compromise the vapor barrier of the building. The system includes a clip 100 for attaching and supporting a wall panel to a building structure. One example of the clip is described above and shown in Fig. 5. The system of Fig. 4 further includes a stud element 109 of a building structure.
The system further includes a vapor barrier 130. The vapor barrier is formed of a plurality of interlocking panels 130a and 130b. Each panel 130a includes at least one edge portion 134a that overlaps with at least one edge portion 134b of an adjacent panel 130b.

[0030] The clip 100 is affixed to the stud element 109 of the building structure through a hole 136 in the edge portion 134a of a first panel 130a. The edge 134b of an adjacent panel 130b interlocks with the edge 134a of the first panel 130a such that the hole 136 through which the clip 100 is anchored to the stud 109 is sealed and the vapor barrier 130 is not compromised. In the vapor barrier panel system of the '181 patent and/or Exhibits B, C and D of U.S. provisional patent application number 61/509,109, the panels 130a and 130b include interlocking tongue-and-groove edges.

[0031] As is shown in Fig. 4, a hat subgirt 150 is attached to the clip 100 by extending a screw 155 through the face portion 108 of the clip 100. The exterior façade panels 160a and 160b are then attached to the subgirt 150 via other screws 155a. The clip 100 is located at the top tongue section 134a of an insulated steel sandwich vapor barrier panel 130a that includes a tongue and groove interlocking system with adjacent vapor barrier panels 130b. A sealant material 137 is located in the tongue and groove as shown in Fig. 4. As is shown in Fig. 4, the downward central flange portion 104 of the clip 100 extends into the foam portion 134a of the vapor barrier panel 130a at a location in which the foam is exposed (i.e. the steel sheeting does not continue around the entire tongue portion of the top of the panel). The anchor 107 to attach the clip 100 extends through the steel sheet on both the exterior and interior surfaces of the vapor barrier panel 130a and into the stud 109.

[0032] As further shown in Fig. 4, an interior section 163a of the support bracket 163 is screwed to the subgirt 150. Filler strip 163b be is screwed to section 163a, and top section 163c is connected to filler strip 163b via an overlapping tongue and groove relationship. It will be appreciated that in alternative embodiments, a single piece bracket, or even direct connection of facade panels 160 to the subgirt 150 may be utilized. Furthermore, it will be appreciated that any type of facade may be attached utilizing the system of the instant invention.

[0033) Referring to Fig. 6, another embodiment of a system of the instant invention, similar to that of Fig. 4, is shown with a one piece bracket connecting the subgirt to the facade panels. As is shown in Fig. 6, a hat subgirt 150 is attached to the clip 100 by extending a screw 155 through the face portion 108 of the clip 100. The exterior facade panels 160a and 160b are then attached to the subgirt 150 via screws 155a (not shown in Fig. 6). The clip 100 is located at the top tongue section 134a of an insulated steel sandwich vapor barrier panel 130a that includes a tongue and groove interlocking system with adjacent vapor barrier panels 130b. A sealant material may be located in the tongue and groove in the manner shown in Fig. 4. The downward central flange portion 104 of the clip 100 extends into the foam portion 134a of the vapor barrier panel 130a at a location in which the foam is exposed (i.e. the steel sheeting does not continue around the entire tongue portion of the top of the panel). The anchor 107 to attach the clip 100 extends through the steel sheet on both the exterior and interior surfaces of the vapor barrier panel 130a and into the stud 109. As further shown in Fig. 6, one-piece support bracket 163 is screwed to the subgirt 150. Bracket 163 shown in Fig. 6 is shaped as a unitary piece to receive exterior facade panels 160a and 160b and includes a filler surface similar to the filler strip 163b of Fig. 4 as part of the unitary piece. In the embodiment shown in Fig. 6, a separate top section fits into the one piece bracket 163 through a tongue and groove relationship. Panel 160b is connected to the top section, while panel 160a is connected to bracket 163 directly. It will be appreciated that in alternative embodiments, or even direct connection of facade panels 160 to the subgirt 150 may be utilized. Furthermore, it will be appreciated that any type of façade may be attached utilizing the system of the instant invention.

[0034] In some embodiments of the system, an exterior facade 160 is affixed to an outer portion 108 of the clip 100 such that the integrity of the vapor barrier 130 is not compromised. In some embodiments, a portion 104 of the clip 100 penetrates the edge portion 134a of the first panel 130a. In some embodiments, a pressure equalizing void 190 is maintained between the vapor barrier 130 and the exterior facade 160.

[0035] Methods for supporting wall panels are provided. The methods described herein do not compromise the vapor barrier of the wall. The method includes affixing a main body portion 102 of a clip 100 to a stud element 109 of the building structure through a hole 136 in an edge portion 134a of a first panel 130a and interlocking the first panel 130a with an adjacent panel 130b such that the hole 136 in the edge portion 134a of the first panel 130a is covered by an overlapping portion 134b of the adjacent panel 130b. The interlocking and overlapping first 130a and adjacent 130b panels form a vapor barrier 130 that is not compromised by the clip 100 which is used to support the vapor barrier panels 130a and 130b and affixed to the stud 109 of the building frame. In some embodiments, the method further includes penetrating the main body portion 102 of the clip 100, the hole 136 in the edge portion 134a of the first panel 130a, and the stud element 109 of the building structure with an anchor 107 to secure the clip 100 and panel 130a to the building structure. In some embodiments, the method further includes affixing an exterior façade 160 to an outer portion 108 of the clip 100 without compromising the vapor barrier 130.
