PROBLEM TO BE SOLVED: To simply and rapidly couple together block bodies by a method wherein locking of one side of a protrusion coupling tool at a recessed coupling tool is joined in a screwed-in state, pushing, gap filling, or adhesion, and locking of the other side is effected through mating, engaging, or fitting-in. SOLUTION: A protrusion coupling tool 4 and locking recessed coupling tools 2, 2, and 3 are respectively fixed in one or more spots at two block bodies 1... to be coupled together. In the block body 1 for building, locking between one side of the protrusion coupling tool 4 and the recessed coupling tools 2 and 3 is effected through joining in a screws-in state, pushing, gap filling or adhesion. Further, locking between the other side of the protrusion coupling tool 4 and the recessed coupling tools 2 and 3 is effected through mating, engaging, or fittingin. By securing embedding the recessed coupling tool 2 in the joining surface of the block body 1, the two block bodies 1 are joined with each other. This constitution effects simple and rapid coupling without using a tool and an auxiliary material and high-precisely and accurately stocks. |
