PURPOSE:To exactly set the anchor bolts of a foundation by a method in which before concrete is hardened, the positions of anchor bolts are corrected by matching them with the coupling holes of interval spacing plates. CONSTITUTION:Before the foundation concrete 4 is hardened, L-shaped spacing plates 2 are set on the corners by fitting the upper ends of the corresponding anchor bolts 5 into the coupling holes 2a of the plates 2. In case where the fitting of the bolts 5 into the coupling holes 2a is impossible due to the deviation of position, the fitting of the bolts 5 into the coupling holes 2a is performed while correcting the positions by moving the bolts 5. Belt-shaped spacing plates 1 are then set while fitting the upper ends of the corresponding bolts 5 into the coupling holes 1a with correction. |
