Hollow modular construction block - has externally cut weakening notches to permit division block into segments

摘要

Each building block has a number of solid segments (100), each having an interior cavity (110) extending vertically and of octagonal section. Each segment is separable from an adjacent segment by block cutting on a first transverse cut plane (P1,P'1). Each segment is itself separable into two symmetrical halves by cutting on a second transverse cut plane through the octagonal cavity. The junction zone of adjacent segments has a vertical cavity (140), symmetrical w.r.t the first cut plane. The two halves separated by the cavity each form a vertical channel (141,142) to take joining mortar.
