PURPOSE:To prevent the breaking trouble of an anchor bolt as well as raise the efficiency of construction work by a method in which a foundation body is fixed to a footing through anchor bolts inserted into holes vertically piercing the foundation body. CONSTITUTION:A foundation body 3 is inserted into the recessed groove 4 of a footing 2 set under the ground 10 and set by matching a buried nut 5 and the hole 7 of the foundation body 3 positionally. An anchor bolt 8 is inserted through the hole 7, the male screw 8b of the lower end is screwed with the nut 5, and the fixed nut 9 of an upper end screw 8a projected upwards from the upper end 3a of the body 3 is clamped until touching the upper end 3a. The body 3 and the footing 2 are unified. A framework 13 placed on the body 3 is fixed by a nut 14 fitted to the screw 8a. Accordingly, body installation work can smoothly be conducted simply, and the breaking trouble of the anchor bolt can be prevented.
