Abstract
Abstract The present invention describes a unique wall construction and spacer for use by unskilled labor in such construction. Preferably, the wall comprises a plurality of blocks arranged in layers one above the other, each of the blocks having an exterior face, an interior face, a top and a bottom, the top and bottom of each block having a longitudinal groove therein aligned with the grooves of adjacent blocks. The spacer comprises a base supported against the interior faces of adjacent blocks, and first and second arms extending transversely from the base and supported against the tops of said adjacent blocks. The arms are preferably cut-out portions of the base. Each arm includes at its distal end a tab projecting transversely from the arm and having first and second portions, the first portion for extending downwardly into the groove of a block underlying the arm and the second portion for extending upwardly into the groove of the block overlying the arm.

Total Claims: 17
Claim 1
Independent Claim
221 words
A wall, comprising: a plurality of blocks arranged in at least first and second layers spaced one above the other by a predetermined distance, each of the blocks having an exterior face, an interior face, a top and a bottom, the top and bottom of each block having a longitudinal groove located a predetermined distance from the interior face and adapted to be aligned with the grooves of adjacent blocks, wherein the tops of adjacent blocks in each layer are located in a common plane; a plurality of spacers each having a base supported against the interior faces of adjacent blocks in the first layer, each spacer having first and second arms with each arm extending transversely from the base in a plane perpendicular to the common plane, each arm having an upper edge supported against the bottom of a block in the second layer and a lower edge supported against the top of a block in the first layer, each arm including at its distal end a tab having first and second portions, the first portion extending downwardly into the longitudinal groove of a block in the first layer and the second portion extending upwardly into the longitudinal groove of a block in the second layer; and a cementitious material located in the space between the first and second layers.
Claim 2
Dependent Claim
221 words
A wall, comprising: a plurality of blocks arranged in at least first and second layers spaced one above the other by a predetermined distance, each of the blocks having an exterior face, an interior face, a top and a bottom, the top and bottom of each block having a longitudinal groove located a predetermined distance from the interior face and adapted to be aligned with the grooves of adjacent blocks, wherein the tops of adjacent blocks in each layer are located in a common plane; a plurality of spacers each having a base supported against the interior faces of adjacent blocks in the first layer, each spacer having first and second arms with each arm extending transversely from the base in a plane perpendicular to the common plane, each arm having an upper edge supported against the bottom of a block in the second layer and a lower edge supported against the top of a block in the first layer, each arm including at its distal end a tab having first and second portions, the first portion extending downwardly into the longitudinal groove of a block in the first layer and the second portion extending upwardly into the longitudinal groove of a block in the second layer; and a cementitious material located in the space between the first and second layers.
Claim 3
Dependent Claim
19 words
The wall as described in claim 1 wherein the first and second arms are cut-out portions of the base.
Claim 4
Dependent Claim
14 words
The wall as described in claim 1 wherein the spacer is formed of steel.
Claim 5
Dependent Claim
15 words
The wall as described in claim 1 wherein the spacer is formed of rigid cardboard.
Claim 6
Dependent Claim
26 words
The wall as described in claim 1 wherein each arm of the spacer is sized to correspond to a height of a mortar joint between layers.
Claim 7
Dependent Claim
38 words
The wall as described in claim 1 wherein at least one of the spacers includes a line of weakness along a mid-portion of the spacer to enable the spacer to be bent into first and second transverse sections.

Claim 9
Dependent Claim
208 words
A spacer for use in the construction of a wall comprising a plurality of blocks arranged in at least first and second layers spaced one above the other by a predetermined distance, each of the blocks having an exterior face, an interior face, a top and a bottom, the top and bottom of each block having a longitudinal groove located a predetermined distance from the interior face and adapted to be aligned with the grooves of adjacent blocks, wherein the tops of adjacent blocks in each layer are located in a common plane, comprising: a base for support against the interior faces of adjacent blocks in the first layer; and first and second arms extending transversely from the base in a plane perpendicular to the common plane, each arm having an upper edge for supporting a bottom of a block in the second layer and a lower edge for supporting a top of the block in the first layer, each arm including at its distal end a tab having first and second portions, the first portion for extending downwardly into the longitudinal groove of a block in the first layer and the second portion for extending upwardly into the longitudinal groove of a block in the second layer.
Claim 10
Dependent Claim
