<p>The present invention describes a unique wall construction (10) and spacer for use by unskilled labor in such construction. Preferably, the wall comprises a plurality of blocks (20) arranged in layers (18a-18e) one above the other, each of the blocks having an exterior face (22), an interior face (24), a top (26) and a bottom (28), the top and bottom of each block having a longitudinal groove (32) 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 (42) projecting transversely from the arm and having first and second portions (44, 46), the first portion (44) for extending downwardly into the groove of a block underlying the arm and the second portion (46) for extending upwardly into the groove of the block overlying the arm.</p> |
