PURPOSE:To enable concrete blocks to be located in a stable state, by a method wherein struts are formed in a manner that the struts are protruded in a right- angled direction from each surface of a cube-shaped concrete block body. CONSTITUTION:6 struts 2, having about the same size as that of a concrete block body 1, are formed in a manner that they are protruded in a right-angled direction from each surface of the boty 1. If the concrete block is placed such that it is supported to a ground by means of the three struts 2 of the 6 struts 2, a whole shape is formed in a hexagonal contour in a plane, and support legs 3, each having a flat under surface 4, respectively are protruded from the forward end of the strut 2. When the concrete blocks are piled up, the upper surface of each of the protruding struts 2, protruded upward, is forced into contact with the under surface of the lower strut 2 of each of the piled-up concrete blocks. |
