Abstract
Abstract A lightweight structural concrete wall panel for house construction, includes a sandwich construction of two thin fiber reinforced concrete faces enclosing vertical panels of insulation material consisting of expanded polystyrene. Vertical structural concrete ribs between the insulation panels are used to interconnect the concrete faces. A continuous track system cast in the upper edge of the panel and projecting connect bars at the lower edge of the wall, connecting this wall to the surrounding structure in such a manner that the floor slab can be poured after erecting the walls. The face of the wall panel can be cast in such a manner as to appear as siding or another desirable building surface. Window and door openings can also be cast into this wall.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
115 words
A wall panel having a height and a width and top and bottom edges, said wall panel comprising at least one block of insulative material surrounded by a monolithically poured cementious material, each of said at least one block of insulative material extending through substantially the entire height of said wall panel but for relatively narrow portions of said wall panel located along each of the top and bottom edges of said wall panel, wherein said top edge of said panel has a continuous track formed therein adapted to facilitate the joining of said panel with adjacent structure, and wherein said panel further comprises floor connection means adapted to project into a subsequently cast floor.
Claim 2
Dependent Claim
115 words
A wall panel having a height and a width and top and bottom edges, said wall panel comprising at least one block of insulative material surrounded by a monolithically poured cementious material, each of said at least one block of insulative material extending through substantially the entire height of said wall panel but for relatively narrow portions of said wall panel located along each of the top and bottom edges of said wall panel, wherein said top edge of said panel has a continuous track formed therein adapted to facilitate the joining of said panel with adjacent structure, and wherein said panel further comprises floor connection means adapted to project into a subsequently cast floor.
Claim 3
Dependent Claim
15 words
The wall panel of claim 1 wherein said track is cast in said cementious material.
Claim 4
Dependent Claim
69 words
The wall panel of claim 1 wherein said at least one block of insulative material is a plurality of blocks of insulative material, each of which extends through substantially the entire height of said wall panel but for said relatively narrow portions of said wall panel located along the top and bottom edges of said wall panel and each of which is surrounded by said monolithically poured cementious material.
Claim 5
Dependent Claim
33 words
The wall panel of claim 3 wherein said blocks of insulative material are disposed in spaced apart relationship to each other and each of which is surrounded by said monolithically poured cementious material.
Claim 6
Dependent Claim
19 words
The wall panel of claim 4 wherein each of said blocks of insulative material has ends having tapered corners.
Claim 7
Dependent Claim
43 words
The wall panel of claim 5 wherein said blocks of insulative material are aligned so that at least one cementious structural rib extends substantially from near said bottom edge of said panel to near an oppositely disclosed said top edge of said panel.
Claim 8
Dependent Claim
16 words
The wall panel of claim 5 in which said cementious material is reinforced with fibrous material.
Claim 9
Dependent Claim
15 words
The wall panel of claim 5 in which said insulative material is expanded polystyrene panels.
Claim 10
Dependent Claim
33 words
The wall panel of claim 5 in which said floor connection means are steel bars that are partially cast in said wall panel and are adapted to project into the subsequently cast floor.
Claim 11
Dependent Claim
22 words
The wall panel of claim 5 in which steel reinforcing bars are used to reinforce at least one edge of said panel.
Claim 12
Dependent Claim
39 words
The wall panel of claim 5 in which a surface texture of one or more faces of said panel is cast in such a manner as to give an appearance of another construction material such as siding, or bricks.
