A construction block comprises parallel faces joined by four side edges. Two side edges have outer spacing flanges while the other two side edges have inner spacing flanges. The inner flanges are received within a recess defined by the outer flanges. Hook receptacles located on the lower portion of the outer spacing flanges receive hooks located along the length of the inner spacing flanges when two blocks are interconnected, holding the two blocks firmly to each other. The interfacing flanges provide spacing support and integrity and a location for flange to flange ultrasonic spot welding. A structural bar is positionable within the recess of the inner spacing flanges.
