Abstract
Abstract Prefabricated architectural or decorative wall system having thin slabs of decorative materials, such as marble, granite, other natural stone or aggregates thereof, or other decorative exterior finish material, as an exterior finish bonded to the exterior of a thermally insulated structural panel. Such wall panels, including door and window openings are prefabricated at a plant location and assembled at the building site by use of internal fastening means. Each section or panel is itself a structural member and the system requires no frame or "superstructure" for support. The decorative exterior slabs are placed in rows or designs as aesthetics may dictate with adjoining edges spaced apart and those spaces filled with chemically modified concrete, grout or caulking to match material to be placed between adjoining panels on assembly.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
208 words
A panel for use in building construction comprising in combination: a core of ridged heat insulation, generally rectangular in shape with opposed major surfaces, opposed longitudinal edges and opposed ends; a first and a second U-shaped chanel, each having a first and a second leg, attached over said opposed longitudinal edges whereby the first said leg engages one of said opposed major surfaces and the second said leg engages the other of said opposed major surfaces; a first and second sheeting, the said first sheeting attached to one of said opposed major surfaces and said legs engaging the same and the said second sheeting attached to the other of said opposed major surfaces and said legs engaging the same; a first and second flange permanently attached respectively to said first and second channel, each said flange having attaching means whereby the same may be attached to the opposite flange of another panel; facade adhesively bonded to the exposed surface said first sheeting throughout their contacting surfaces and extending beyond the said first sheeting longitudinal edges to the far edges of said flanges; and a top and a bottom end cap placed on said opposed ends, between said channel legs and between said sheeting to form convenient attaching surfaces.

Claim 3
Dependent Claim
18 words
The panel according to claim 1 wherein said first and second sheeting is wafer board, plywood, or Structurwood®.
Claim 4
Dependent Claim
50 words
The panel according to claim 2 wherein said first and second second flange are C-shaped channels and wherein said attacking means are a series of metal plates with receptacles in either end thereof to receive a bolt, which said bolt attaches to a nut wedgedly located inside said C-shaped channel.
Claim 5
Dependent Claim
14 words
