Abstract
Abstract A construction block comprising a generally rectangular hollow body having a pair of faces joined by side edges. There are spacing flanges extending about the side edges around the perimeter of the block adjacent and essentially parallel to the faces to ensure correct spacing of the blocks when arranged in a wall construction. Cavities for connecting adjacent blocks together are provided at each corner of the block. There is a spanning member having ends adapted for engagement in the cavities of adjacent blocks in order to connect blocks into a unified wall structure.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
92 words
A construction block comprising a generally rectangular hollow body having a pair of faces joined by side edges; spacing flanges extending about said side edges adjacent and essentially parallel to said faces to ensure correct spacing of said blocks when arranged in a wall construction; cavities for connecting adjacent blocks together at each corner of said block having a T-shaped cross-section; and connecting means comprising a spanning member having correspondingly shaped T-ends adapted for engagement in said cavities of adjacent blocks in order to connect said blocks into a unified wall structure;
Claim 2
Dependent Claim
92 words
A construction block comprising a generally rectangular hollow body having a pair of faces joined by side edges; spacing flanges extending about said side edges adjacent and essentially parallel to said faces to ensure correct spacing of said blocks when arranged in a wall construction; cavities for connecting adjacent blocks together at each corner of said block having a T-shaped cross-section; and connecting means comprising a spanning member having correspondingly shaped T-ends adapted for engagement in said cavities of adjacent blocks in order to connect said blocks into a unified wall structure;
Claim 3
Dependent Claim
23 words
A construction block as claimed in claim 1 including alignment pins on said side edges to position reinforcement members extending between the blocks.
Claim 4
Dependent Claim
17 words
A construction block as claimed in claim 1 in which said block is formed from translucent plastic.
Claim 5
Dependent Claim
37 words
A construction block as claimed in claim 1 including interlocking flanges extending from said spacing flanges, said interlocking flanges being adapted to be interfitted between the spacing flanges of an adjacent block to provide an interlocking fit.
Claim 6
Dependent Claim
37 words
A construction block as claimed in claim 1 in combination with an alignment strip having mounting means for attachment to a reference surface and alignment means for positioning said construction blocks with respect to said reference surface.
Claim 7
Dependent Claim
21 words
A construction block as claimed in claim 5 in which said mounting means is an adhesive backing on said alignment strip.
Claim 8
Dependent Claim
41 words
A construction block as claimed in claim 5 in which said alignment means comprises a protruding portion of said alignment strip dimensioned to fit between said cavities of said construction block thereby positioning said block with respect to said reference surface.
