Abstract
Abstract A building panel comprises a rectangular substantially flat block of foam material having a plurality of parallel grooves in the inner face thereof. A plurality of similar panels are assembled in edge-to-edge relationship to form a wall and a spacer is received within the aligned grooves of a plurality of building panels. A second wall spaced from the first wall is formed of a similar plurality of panels and the spacer member is received within the opposed grooves of the inner faces of both walls so that a space is formed between the walls. Opposed blocks in the walls are clamped together to align the walls.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
188 words
A wall structure comprising a plurality of rectangular substantially flat blocks positioned in a plurality of horizontal rows in edge-to-edge relationship to form an outer wall, a second plurality of rectangular substantially flat blocks positioned in a plurality of horizontal rows in edge-to-edge relationship to form an inner wall spaced from said outer wall, the inner faces of said blocks each having a plurality of vertically extending grooves therein such that the grooves of the several rows of blocks are aligned, an elongated spacer member vertically positioned in one pair of opposed rows in each block of said inner and outer walls and extending from top to bottom thereof, and elongated spacer members of varying lengths are positioned in abutting relationship in another pair of opposed rows in each block whereby the uppermost of said last mentioned spacer members extend upwardly into alternate grooves in a block of a row thereabove, and means interposed between said spacer members and straddling and embedded in vertically abutting blocks of each row for clamping horizontal edges of opposed blocks in said inner and outer walls to align the panels in position.
Claim 2
Dependent Claim
188 words
A wall structure comprising a plurality of rectangular substantially flat blocks positioned in a plurality of horizontal rows in edge-to-edge relationship to form an outer wall, a second plurality of rectangular substantially flat blocks positioned in a plurality of horizontal rows in edge-to-edge relationship to form an inner wall spaced from said outer wall, the inner faces of said blocks each having a plurality of vertically extending grooves therein such that the grooves of the several rows of blocks are aligned, an elongated spacer member vertically positioned in one pair of opposed rows in each block of said inner and outer walls and extending from top to bottom thereof, and elongated spacer members of varying lengths are positioned in abutting relationship in another pair of opposed rows in each block whereby the uppermost of said last mentioned spacer members extend upwardly into alternate grooves in a block of a row thereabove, and means interposed between said spacer members and straddling and embedded in vertically abutting blocks of each row for clamping horizontal edges of opposed blocks in said inner and outer walls to align the panels in position.
Claim 3
Dependent Claim
16 words
A wall structure as claimed in claim 1 wherein said spacer has a rectangular cross section.
Claim 4
Dependent Claim
25 words
A wall structure as claimed in claim 2 wherein said grooves each have a cross section corresponding to the cross section of the spacer member.
Claim 5
Dependent Claim
20 words
A wall structure as claimed in claim 1 and further comprising a clamp having upwardly and downwardly extending three-point prongs.
Claim 6
Dependent Claim
32 words
A wall structure as claimed in claim 1 wherein the space between said inner and outer walls is filled with concrete to form a unified reinforced concrete upright having greater load-bearing capacity.
