Abstract

PURPOSE:To increase strength and prevent water leakage by penetrating mortar up to a close proximity to a junction edge. CONSTITUTION:Respective blocks provided with a polygonal front face body 1, and a shell 2 and a junction protrusion 5 formed at the rear of the front face body so that the rear of the front face body may become narrow are made to come into linear contact with each other of junction edges 4, so that mortar penetrates up to a close proximity to a junction side 3 and the junction edge 4. It is thus possible to increase strength, prevent water leakage, make weathering difficult, and make it easy to absorb a manufacturing error for easy work man ship. In other words, when the manufacturing error exists and the junction edge 4 is high a little, it is possible to absorb the error by shifting the junction sides 3 and the junction edges 4 at the upper and lower parts from each other.
