ABSTRACT:
This invention provides a block to be used with the block means of similar character to create a form for a concrete wall. The blocks are of lightweight plastic and are of substantially rectangular shape, and have opposite ends, opposite sides, upper and lower interlocking surfaces, a substantially hollow interior compartment, and opposite end walls and opposite side walls. The upper interlocking surfaces comprise an elongated longitudinal rib having a rectangular base and an inverted V-shaped upper surface. These ribs have a width less than that of the side walls, and have a substantially horizontal ledge adjacent either side thereof. Lateral extending ribs spaced from each other extend across the ledges and ribs. The lateral extending ribs also have an inverted V-shaped upper surface which extends from a lower rectangular base portion. A plurlaity of cylindrical plugs extend upwardly in spaced relation from the ribs. The lower interlocking surface is a mere image of the upper interlocking surface. Spanner ribs with a U-shaped notch in the upper portion thereof extend through the interior compartment of the block. The notches are adapted to receive an elongated reinforcing rod. The ends of the blocks have U-shaped openings into which a U-shaped plug can be inserted in locked condition to dam off the end of the block which appears at the end of the concrete wall to be poured.
