<p>The hollow building block has spaced side walls (20, 30) interconnected by integral webs and end walls (32, 32a). In the vertical and horizontal edge surfaces of the side walls tongues (2, 2a) and grooves (1a) are provided adapted to be engageable with grooves and tongues of adjacent blocks. The end walls are recessed and have cutouts to form after assembly communicating vertical and horizontal passages for receiving reinforcing members and to be filled with concrete. The building block system comprises module blocks, half module blocks, quarter module blocks, corner blocks, insulating blocks, closure elements and adaptor elements.</p> |
