Double Locking Mortarless Block

Abstract

The invention is to make a rectangular block that will be used in a construction system based on the combined use of a double locking mortar-less block designed that locks together. The double locking mortar-less block of rectangular configuration with two end cavities of equal size and ears on the middle web. Each ear is the same dimension as the grooves in the internal faces of the end and sidewalls of each cavity. Each groove being positioned, shaped and dimensioned so that an ear and groove of adjacent blocks can be interlocked. The contour face of the block is contoured along axes perpendicular to the top and bottom faces of the block and the block face has protruding and receding portions. The respective protruding and receding portions interlock so that the block is adapted to form a rigid structure.
