ABSTRACT:
A generally rectangular concrete building block of partially hollow construction with at least one large rectangular vertical opening extending therethrough and provided with a generally zig-zag shaped rod embedded in the interior walls and extending transversely of and formed with a transverse loop in the center of each hollow interior. In erecting a wall, a concrete footing is first poured and a plastic sheet having a row of prepunched openings is flatly arranged thereon with the openings so spaced to indicate the positions to be assumed by a series of reinforcing bars when inserted therethrough and embedded within the footing to project vertically therethrough in a row alignable with the hollow blocks. After setting of the concrete the bars are securely anchored in the footing and enable the first course of blocks to be laid thereon with the openings therein and the centrally arranged loops embedded in each block sleeved over the bars so that the block and walls abut and their front surfaces are in alignment. Each successive course of blocks is correspondingly but staggerably arranged on and relative to those in the course below with their rod loops also sleeved over the bars until a mortarless wall of the required height is reached.
