A construction block of generally rectangular form having parallel upper and lower faces between which extend, through the block, one or more wide apertures and a plurality of narrow holes; the end faces of the block have wide grooves which cooperate, in a wall structure constructed from a plurality of horizontal courses of such blocks, to provide chambers between adjacent blocks of a course, the wide apertures in the blocks of adjacent courses cooperating to form vertically extending channels, the narrow holes house locating pins for holding the blocks of adjacent courses together until they are joined by concrete cast into the said vertical channels; the said upper and lower parallel faces have central depressions which form, between adjacent courses of blocks, horizontal channels linking the vertical channels so that the concrete cast into the vertical channels can also flow into and fill the horizontal channels to form an interlinked network giving great strength to the wall.
A wall structure including:
In a construction block of the type having a substantially rectilinear configuration with the upper and lower surfaces having an identical configuration and the opposite end surfaces having an identical configuration, the improvement comprising a single substantially rectilinear aperture extending through said block from said upper surface to said lower surface and which is symmetrical about a median plane of said block parallel to an end surface of said block and a recess in each end face identical to one half of said aperture on one side of said median plane, said upper and lower surfaces having a pair of parallel spaced apart flat surfaces located on opposite sides of said aperture and recesses and a depressed portion extending parallel to said flat surfaces, said depressed portion being comprised of two spaced apart channels adjacent each flat surface and a raised central portion having a substantially flat upper surface and a pair of holes for receiving locating pins extending through said block intermediate each recess and said aperture and communicating with said raised central portion on said upper and lower surfaces. parallel to said flat surfaces, said depressed portion being comprised of two spaced apart channels adjacent each flat surface and a raised central portion having a substantially flat upper surface and a pair of holes for receiving locating pins extending through said block intermediate each recess and said aperture and communicating with said raised central portion on said upper and lower surfaces.
