必要で面倒であるという施工上の問題がある。[0006] For example, Japanese Utility Model Publication No. 53-47761 discloses a cross-shaped building block, in which the position of the small connecting recess is determined by the position of the projecting end of the block.
It is an annular part that protrudes into the small recesses on both side edges.
The connecting means comprises a U-shaped connecting bracket and a bolt.
These parts are expensive and always require screw tightening.
There is a construction problem that it is necessary and troublesome .

る。As is clear from the above description, according to the present invention, since the outer peripheral edge of the main body of each block is formed in a cross shape, the construction can be performed while rotating these blocks.
The joint lines between the blocks are greatly indented uneven lines, and the blocks are firmly fitted in both up, down, left, and right directions, and many combinations are possible by rotating the stone uneven surface in one or several types of patterns Becomes The block of the present invention has four cross-shaped outer edges 1A.
Small recesses 2 are formed at each of the centers of the protruding ends,
The head 3A of the bolt connecting rod 3 protrudes from the center of each small recess 2.
And the axial direction of the connecting rod 3 and the projecting direction of the projecting end.
And the horizontal direction.
The heads 3A of the connecting rod 3 of the small recess 2 facing each other are substantially U-shaped.
The fitting rod 4 is fitted into the engaging portion 4A at both ends of the
And the connecting piece is easily is transported and assembly work less expensive, since usually no bolting operations during assembling construction which is an operation for fitting the connecting piece to the head of the connecting rod, the construction work is inefficient is there.
