CONCRETE BUILDING BLOCK AND CONSTRUCTION METHOD FOR WALL BODY BY CONCRETE BUILDING BLOCK

摘要

PROBLEM TO BE SOLVED: To provide a concrete building block capable of easily and properly constructing a wall body protecting a slope.;SOLUTION: A stay part 4 having a cross section smaller in area than the surface 1A of a front head part 1 and a predetermined length is formed on the rear of the front head part 1 with the surface 1A formed in a square shape. A stay hip 2 having a square-shaped surface facing the front head part 1 is formed at the tip of the stay part 4. The stay hip 2 is twisted by 45° relative to the front head part 1, and when the front head parts 1 are stacked by uncoursed masonry, the stay hips 2 are continued with each other vertically and laterally and their end faces are brought into contact with each other. As a result, the predetermined wall body can be easily and properly constructed by stacking the blocks in a parallel state without allowing pebbles to be pinched between the stay parts 4.;COPYRIGHT: (C)2007,JPO&INPIT
