Abstract
Abstract A multi-layer, wall panel is disclosed that is adapted by itself to form a complete structural wall of a building. In one form, the panel has a sandwich construction comprising an outer layer of masonry building units such as bricks, an internal, relatively lightweight, principally load-bearing layer of cementitious material, and an insulating layer adapted to receive fasteners by which an inner decorative layer may be fixed to the panel construction. Preferably, frame members are mounted about the edges of one or more panels to unify the structure.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
192 words
A multi-lAyer, prefabricated wall panel adapted by itself to form a complete structural wall member without contact or support with other wall structures, said wall member comprising in combination a plurality of juxtaposed, contacting layers of substantially equal dimensions at their contacting faces, said layers including: a. a masonry exterior layer of spaced-apart masonry building units, b. a layer of cementitious material defining the principal loadbearing portion of said multi-layer, prefabricated wall panel supporting the units of said masonry layer, some of said cementitious material extending between said building units and simulating mortar or the like, c. a thermal insulating layer contacting said cementitious layer, d. beam means extending along a face of said insulating layer remote from said cementitious layer and sufficiently contained within said insulating layer as to be substantially flush with said remote face of the insulating layer, e. a decorative layer contacting said insulating layer, and f. fastening means extending from said decorative layer through said beam means and into said layer of cementitious material, whereby said last mentioned layer retains all of said layers in assembly to provide structural integrity and define said multilayer, prefabricated wall panel.
Claim 2
Dependent Claim
192 words
A multi-lAyer, prefabricated wall panel adapted by itself to form a complete structural wall member without contact or support with other wall structures, said wall member comprising in combination a plurality of juxtaposed, contacting layers of substantially equal dimensions at their contacting faces, said layers including: a. a masonry exterior layer of spaced-apart masonry building units, b. a layer of cementitious material defining the principal loadbearing portion of said multi-layer, prefabricated wall panel supporting the units of said masonry layer, some of said cementitious material extending between said building units and simulating mortar or the like, c. a thermal insulating layer contacting said cementitious layer, d. beam means extending along a face of said insulating layer remote from said cementitious layer and sufficiently contained within said insulating layer as to be substantially flush with said remote face of the insulating layer, e. a decorative layer contacting said insulating layer, and f. fastening means extending from said decorative layer through said beam means and into said layer of cementitious material, whereby said last mentioned layer retains all of said layers in assembly to provide structural integrity and define said multilayer, prefabricated wall panel.
Claim 3
Dependent Claim
15 words
The prefabricated wall panel of claim 1 in which said decorative layer is wood paneling.
Claim 4
Dependent Claim
19 words
The prefabricated wall panel of claim 1 in which said masonry building units are bricks, stones, rocks, or tile.
Claim 5
Dependent Claim
20 words
The prefabricated wall panel of claim 1 in which said layer of cementitious layer is a layer of air-entrained concrete.
Claim 6
Dependent Claim
18 words
The prefabricated wall panel of claim 1 in which said insulating layer comprises a batt of mineral fibers.
Claim 7
Dependent Claim
24 words
The prefabricated wall panel of claim 1 in which said beam means comprises wooden members spaced on said remote face of said insulating layer.
Claim 8
Dependent Claim
21 words
The prefabricated wall panel of claim 1 in which said layer of cementitious material contains mesh means for reinforcing said layer.
Claim 9
Dependent Claim
14 words
The prefabricated wall panel of claim 1 including means for lifting the wall panel.
Claim 10
Dependent Claim
36 words
The prefabricated wall panel of claim 1 including means for lifting the wall panel comprising rod means extending from within the panel away therefrom in a direction substantially parallel to a major face of the panel.
Claim 11
Dependent Claim
23 words
The prefabricated wall panel of claim 1 including sealing means between at least two contiguous layers extending along the sides of said layers.
Claim 12
Dependent Claim
58 words
The prefabricated wall panel of claim 1 including gasket means between said layer of cementitious material and each of said masonry layer and said insulating layer, said gasket means extending around the complete periphery of said layers to render said prefabricated wall substantially air and water tight and to permit expansion of said layers relatively to each other.
Claim 13
Dependent Claim
24 words
The prefabricated wall panel of claim 1 including frame members mounted on at least one of the upper and lower edges of the panel.
Claim 14
Dependent Claim
68 words

Claim 15
Dependent Claim
76 words
The prefabricated wall panel of claim 13 including a vertically disposed post member contacting a side of said panel, one face of said post member substantially parallel to said panel member having a vertically extending flange member for receiving said panel thereagainst, the opposed face of said panel member being free of corresponding obstruction to permit mounting of the panel with respect to said post member and channel members, and to receive said face plate member.
Claim 16
Dependent Claim
18 words
The prefabricated wall panel of claim 13 in which said substanTially flat face plate has an inverted U-shape.
