<p>PURPOSE: A new shape of a block for coating a middle part is provided which improves a stability as improving a construction property. CONSTITUTION: An installation of a block contains the steps of: forming an upper/lower through hole(10) of a diamond shape at the center of a pillar, also at a hexahedron of a right square pillar shape, forming a bridge(12) of a shape which one face of a regular square pillar is conjugated at the rim of the side of the pillar, forming a foot(14) which the upper end and the lower end of the bridge(12) is slightly projected upward/downward from the upper face and the lower face of the hexahedron, and imitating an edge of the foot(14) and the bridge(12). The through hole(10) is for dispersing a stress of the block, also for passing a water vein, and also prevents a concentration of the stress due to the formation as a diamond shape. Also, the foot(14) projected upwardly/downwardly is for improving a combination force with a coating stone of an upper layer and a lower layer.</p> |
