Abstract

A brick or building block integrally formed of a rigid molded plastic material, for example polyvinyl chloride, and consisting of a hollow thin-walled rectangular box-shaped body, having an outer peripheral wall and having at least one vertical transverse partition. Internal that divides the hollow interior symmetrically in a plurality of independent square or semi-square cells that are open in the upper part and in the lower part, the upper part of the peripheral wall and of each partition having formed parts of flange or displaced vertical projections towards the inside that project over the inside of the cells and constitute male parts destined to fit inside and lock in fixed position in the open lower end of the cellular interior of a brick or similar block mounted above so that the aligned cells are interconnected vertically, wherein each adjacent, inter-cell partition extends substantially throughout the body depth: it carries a distanced pair of vertical male flange or shoulder portions that form opposing sides along the opposite edges. Of an open channel extending transversely through the body along said partition and which is intended to accommodate the combined thickness of the lower edge portion. Of two opposite sides of the peripheral wall so as to allow a plurality of similar bricks or blocks to be mounted in staggered or longitudinally displaced relation to provide wall constructions in which they are produced, continuous vertically extending tubular spaces, closed laterally, by similar cells aligned vertically of the bricks or blocks of the different courses.
