  • Patent number: 6588168
    Abstract: Provided herein are blocks useful in the construction of walls and other structures. The blocks include in their design features which render them to be interlocking, and which provide for a wall constructed from the blocks to include a plurality of horizontal and vertical channels that are adapted to receive reinforcing rods (“rebar”). Once a two-dimensional network of rebar is disposed in the interior of such a wall constructed from blocks according to a preferred form of the invention, a castable concrete may be poured into the wall and caused to exist in the spaces between the rebar and the blocks of the invention. By such construction, a wall comprising concrete in its interior that is reinforced in two dimensions is provided, wherein reinforcement in the third dimension is provided by the interlocking feature of the tops and bottom portions of blocks in adjacent rows with one another.
