Each block of the material A has a penetrating hole 7 within itself in a horizontal direction in such a way as to correspond to the holes in other blocks, and a locking bolt 8 is inserted to penetrate the holes 7 in the blocks of the material A. Blocks of the material A are bound together by a locknut 9 which has a matching thread with that of the bolt 8.;COPYRIGHT: (C)1994,JPO&Japio
