PURPOSE:To build up the extent of connection by mounting each block, provided with a fitting part on both the sides, on a footing part formed with the fitting part on a top face, stacking these blocks in pile successively, while inserting a reinforcing bar into an insert hole with one another, and forming a pier part by means of mortar anchoring. CONSTITUTION:A footing part 1A, provided with either of a fitting projection 11A or recess 12A on a top face, is formed up, and on this footing part 1A, there is mounted a block 7A provided with the underside being fitted in this footing part. In addition, the block 7A is fitted in the footing part 1A, and another block 7A is stacked on the top face successively in pile likewise. Then, a reinforcing bar 20A projected out of either of the footing part 1A or block 7A is inserted into an insert hole 15A, then mortar is filled up in it, locking the block 7A, thus a pier part 4A is formed on the footing part 1A. With this constitution, the number of operators is reduced and, what is more, a construction period is reducible. |
