Abstract
Abstract In a prefabricated building wall panel a rigid supporting frame is covered on one face by masonry or ceramic cladding, the cladding being held to the supporting frame by a composite fastener system comprising rigid supports underlying the cladding to carry the dead loading thereof with resilient means adhesively securing the cladding to the support frame to resist live loading thereof.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
168 words
In a wall structure for a building having a building framework and a plurality of prefabricated panel sections secured to the building framework to form a wall surface, each panel section comprising: a rigid support structure for attachment to the building framework and including a rigid deck substantially co-extensive with the support structure; a plurality of fascia panels overlying said support structure, said fascia panels having opposite front and back faces with the back face opposing the disposed closely adjacent the rigid deck, said panels formed of materials selected from the group consisting of ceramics and masonry; rigid means for supporting the dead load of said fascia panels on said support structure while permitting relative movement between the fascia panels and support structure; means distributed across the back face of the panels between such face and the rigid deck for resiliently supporting and distributing the live load of said fascia panels on said support structure; and means for sealing the joints between adjacent edges of the fascia panels.
Claim 2
Dependent Claim
168 words

Claim 3
Dependent Claim
30 words
The invention defined by claim 1 wherein said rigid support structure includes a structural frame and a sheet metal deck overlying one side of the frame and rigidly secured thereto.
Claim 4
Dependent Claim
31 words
The invention defined by claim 2 wherein said means for rigidly supporting the dead load and said means for resiliently supporting the live load are secured to said sheet metal deck.
Claim 5
Dependent Claim
15 words
The invention defined by claim 2 wherein said sheet metal deck comprises a flat sheet.
Claim 6
Dependent Claim
19 words
The invention defined by claim 2 wherein said sheet metal deck is formed to provide parallel ridges and grooves.
Claim 7
Dependent Claim
60 words
The invention defined by claim 1 wherein upper and lower horizontal edges connect said faces and kerfs are provided in at least the lower of such edges spaced between said faces; and said rigid means comprises retainers on the support structure having flanges underlying the lower horizontal edges of the fascia panels, said flanges having lips received in said kerfs.
Claim 8
Dependent Claim
42 words
The invention defined by claim 6 wherein said kerfs have a front to rear dimension exceeding the thickness of said lips permitting limited relative movement of the fascia panels in respect to said rigid support structure under the influence of live loading.
Claim 9
Dependent Claim
68 words
The invention defined by claim 6 wherein said kerfs are provided in both the upper and lower horizontal edges and said retainers include a back portion attached to the rigid support structure behind the back faces of the fascia panels and a flange portion extending outwardly from the support structure between adjacent rows of fascia panels and terminating in upwardly and downwardly extending lips received in said kerfs.
Claim 10
Dependent Claim
39 words
The invention defined in claim 8 wherein said retainers include a Z-shaped clip and a J-shaped clip nested together to provide a back portion and a flange portion terminating in upwardly and downwardly extending lips received in said kerfs.
Claim 11
Dependent Claim
35 words
The invention defined in claim 9 wherein said back portion is secured to the rigid support structure and the kerfs are oversize the lips permitting limited relative movement between the fascia panels and support structure.
Claim 12
Dependent Claim
34 words
The invention defined by claim 1 wherein said fascia panels each have upper and lower horizontal edges and said rigid means for supporting the dead load of the fascia panels underlies the lower edges.
Claim 13
Dependent Claim
36 words
The invention defined by claim 11 wherein said rigid means for supporting the dead load is secured to the fascia panels to limit movement of the panels away from the support structure under a live load.
Claim 14
Dependent Claim
65 words
The invention defined by claim 12 wherein said fascia panels have vertical faces adjacent the upper and lower horizontal edges facing away from said support structure, and said rigid means are secured to such support structure and have portions overlying said vertical faces to limit movement of the fascia panels away from the support structure independently of said means for resiliently supporting the live load.
Claim 15
Dependent Claim
43 words
The invention defined by claim 13 wherein said rigid means is secured to said support structure at joints between upper and lower edges of adjacent fascia panels, and said rigid means having portions overlying vertical faces of the fascia panels adjacent such joints.
Claim 16
Dependent Claim
50 words
The invention defined by claim 11 wherein said rigid means comprises a T-shaped clip having a head portion and a shank portion with the head portion secured to the rigid support structure and the shank portion underlying the lower edges of the fascia panels and supporting the dead load thereof.
Claim 17
Dependent Claim
41 words
The invention defined by claim 11 wherein said retainers comprise an L-shaped clip having a back portion secured to the rigid support structure and a lip portion underlying the lower edges of the fascia panels and supporting the dead loading thereof.
Claim 18
Dependent Claim
47 words
The invention defined by claim 11 wherein said rigid means comprises a retainer having a cylindrical shank portion and a screw-threaded end for connection to the rigid support structure with a cylindrical shank underlying the lower edges of the fascia panels and supporting the dead load thereof.
Claim 19
Dependent Claim
16 words
The invention defined by claim 17 wherein said shank portion and screw-threaded end are separable elements.
