DETAILED DESCRIPTION OF THE INVENTION

(8) Now referring to the drawings, embodiments of the present innovation are disclosed that relate to a unitized wall panel assembly. In one arrangement, the unitized wall panel assembly is a composite wall system configured to distribute and transfer loads, such as wind loads, through a composite action between the unitized wall panels and the studs of the assembly. Further, the joint design of the composite wall system provides an increase in thermal performance compared to conventional system. For example, the unitized wall panel assembly provides a substantially large thermal R-Value (e.g., an effective R-Value of about 19 or more per ASHREA) for about half the wall depth of conventional panel wall systems. The design is based upon the interaction among an insulated wall panel, thermally efficient joints, and the finish cladding, such as specified by an architect. Accordingly, the composite wall system provide relatively high strength with a smaller wall depth, less weight, and an increase in thermally efficiency compared to conventional construction methods.

(9) Conventional wall panels in the prior art are configured to be disposed on an exterior of a building, such as part of an external faade. The wall panel is typically configured as a substantially rectangular structure defining a longitudinal axis. In one arrangement, the panel is constructed from a foam insulation material, such as a substantially continuous polyisocyanurate insulation material with varying thicknesses. In one arrangement, the wall panel is configured to interlock with adjacently disposed panels to form a substantially continuous insulating structure. Opposing edges of a wall panel define an interlocking splined structure.

(10) In a conventional installation of the wall panels at a work site, studs, such as six inch C-studs, extend vertically relative to a structure. During an assembly procedure, an assembler typically disposes a wall panel relative to the studs such that the longitudinal axis of each panel is substantially perpendicular to the longitudinal axis of each stud. The assembler then secures the wall panel to each of the studs using a fastener and interlocks a subsequent wall panel with the splined structure of the previously secured wall panel.

(11) This conventional layout of the wall panels relative to the studs provides insulation to a building structure. However, such a layout suffers from a variety of deficiencies. For example, when exposed to a wind load, the insulated wall panels do not assist in composite action with that of the studs in transferring the load. Based upon the multipoint connections between the wall panels and studs, when exposed to a loading (e.g., a loading substantially perpendicular to the face of the wall panels, such as caused by the wind) the wall panels transfer the load to the studs.

(12) By contrast, FIG. 1 illustrates an example of a composite wall system 100, according to one arrangement of the innovation. The system 100 is configured to allow the mounting of insulated wall panels 100 in a unitized configuration to an edge-of-slab condition. In such an arrangement, each of the wall panels 100 can span a distance floor-to-floor without requiring any additional support framing.

(13) For example, the system 100 includes a set of panels 110 and a set of studs 120. Each panel of the set 110 is configured as an insulated panel having an interlocking or splined structure formed at the joint 117 between edges 114, 116 of adjacent panels 110. The wall panels 110 are disposed such that the longitudinal axis of each panel 110 is substantially parallel to the longitudinal axis of each stud 120. The edge material at a joint 117 of two adjacent wall panels 110 is coupled to a corresponding stud 122 along the longitudinal axis of the stud. An example of such coupling using fasteners 125 is shown in FIG. 2.

(14) Attachment of the horizontal panel-to-panel joints 117 to the relatively light gauge metal stud 120 combines the strength of both the wall panels 110 and the studs 120 so that they act as a composite structure to support and transfer loads. For example, based upon the longitudinal connections between the wall panels 110 and studs 120, when exposed to a loading (e.g., a loading substantially perpendicular to the face of the wall panels 110, such as caused by the wind) the combination of the wall panels 110 and the studs 120 act to absorb the loading. Additionally, the positioning of the longitudinal axis 112 of the wall panels 110 substantially parallel to the longitudinal axis 122 of the studs 120 minimizes external loading (e.g., a wind load).

(15) Further, the composite wall system is configured to provide a substantially large thermal R-Value (e.g., an effective R-Value of about 19 or more per ASHREA) for about half the wall depth of conventional panel wall systems.

(16) Turning back to FIG. 1, in one arrangement, the wall panel 110 can include an extrusion assembly that extends around at least a portion of wall panel perimeter. For example, a wall panel can be configured with opposing extrusion assemblies on the panel's top and bottom edges (i.e. horizontal extrusions), on the panel's right and left side edges (vertical extrusions), or with an extrusion assembly 200 extending around the entire perimeter of the wall panel 110 (vertical and horizontal extrusions), as illustrated in FIGS. 1 and 3. In each case, the extrusion assembly 200 is configured to provide ease of assembly of the wall panels 110 in the field and to allow relative movement of the wall panels 110 once installed on a structure.

(17) As can be seen the wall panels 110 each having horizontal extrusions 200-1, 200-2 extending along opposing top and bottom edges. The extrusions 200-1, 200-2 are configured to allow mounting of panels 110 to a wall which allows relative horizontal and vertical movements between adjacent panels 110. While the horizontal extrusions 200-1, 200-2 can be configured in a variety of ways, in one arrangement, the first wall panel 110-1 includes a first extrusion 200-1 disposed on a top edge where the first extrusion 200-1 includes a male component 202 which extends along the length of the wall panel 110-1. Further, the second wall panel 110-2 includes a second extrusion 200-2 disposed on a bottom edge where the second extrusion 200-2 defines a channel or female component 204 which extends along the length of the wall panel 110-2. Interconnection of the male and female components of the first and second extrusions 200-1, 200-2 couples the opposing wall panels 110-1, 110-2 to each other. When interconnected, the extrusions 200-1, 200-2 define a space or gap 206 between opposing wall panels 110-1, 110-2 of between about zero inches and 1.5 6 inches. This separation gap 206 isolates the wall panels 110-1, 110-2 from a building or structure 300 and allows for horizontal and vertical building movements while maintaining the integrity of the insulated wall panels 110-1, 110-2 as well as the building envelope's air, vapor, and weather barriers.

(18) FIG. 6 illustrates a top sectional view of adjacent wall panels 110-3, 110-4, each having a vertical extruded perimeter 200-3, 200-4, according to one arrangement. As illustrated, the extruded perimeter 200-3 defines a channel of female component 208 while the extruded perimeter 200-4 includes a male component 210. When interconnected, the extrusions 200-3, 200-4 define a space or gap 212 between opposing wall panels 110-3, 110-4 of between about zero inches and 6 inches. This separation gap 212 isolates the wall panels 110-3, 110-4 from the building or structure 300 and allows for vertical building movement while maintaining the integrity of the insulated wall panels 110-3, 110-4 as well as the building envelope's air, vapor, and weather barriers.

(19) The wall panel assemblies 110, such as provided above, can be secured to a building face in a number of ways. The following provides two example wall panel mounting assemblies that can be utilized to tie the wall panel assemblies 110 to a building face.

(20) FIGS. 1 and 3 illustrate an example of wall panels 110 mounted to the slab edges 250 of a building where the wall panel mounting assembly is configured as a J-bracket assembly 252. For example, the J-bracket assembly 252 is designed for mounting insulated wall panel assemblies 110, in a unitized configuration, to a slab edge 300 and to span the wall panel assemblies 110 floor-to-floor without requiring any additional support framing.

(21) The J-bracket assembly 252 includes a slab edge J hanger bar 254 that is attached to fasteners such as threaded rods 256 which are embedded in the concrete slab 250. The J-bracket assembly 252 also includes a jamb plate 258, a sliding clip 260, and an adjustment bolt 262 that are configures to support the load of the wall panels 110 and transfer the loads to the building structure 300. The J-bracket assembly 252 is disposed at the top and bottom slab edges 300 of the building structure and combines with the strength the wall panel assemblies 110 so that they act compositely to support all imposed loads.

(22) FIG. 5 illustrates a set of wall panels 110 mounted to an existing wall. While the wall panels 110 can be mounted in a variety of ways, in one arrangement, the wall panels mount utilizing a set of Z-bracket assemblies. In one arrangement, the Z-bracket assembly 270 includes a first or bottom z-shaped extrusion 272 and a second or top z-shaped extrusion 274 that interact to secure each wall panel 110-1, 110-2 to a corresponding wall 280-1, 280-2.

(23) In one arrangement, the top extrusion 274 includes adjustable setting fasteners 276, such as bolts, that secure the top extrusion 274 to the corresponding wall panel 110-1. The fasteners 276 are configured to support the weight of the panel assemblies 110 and allow for vertical adjustment of the unitized panel sections 110 during installation. The bottom extrusion 272 is configured to be secured to a wall structure 280 of a building, such as via fasteners 277.

(24) The top extrusion 274 works in conjunction with the bottom extrusion 274 to transfer the weight of the panel 110 to the building structure 280. For example, a portion of the top extrusion 274 is disposed within a gap defined between the bottom extrusion 272 and the wall 280 while a portion of the bottom extrusion 272 is disposed within a gap defined between the top extrusion 274 and the wall panel assembly 110. Accordingly, the top and bottom extrusions 274, 272 interlock together to transfer horizontal loads to the building structure 280 while allow for vertical building movements.

(25) While there is shown and described herein certain specific structure embodying the invention, it will be manifest to those skilled in the art that various modifications and rearrangements of the parts may be made without departing from the spirit and scope of the underlying inventive concept and that the same is not limited to the particular forms herein shown and described except insofar as indicated by the scope of the appended claims.
