溶接を行なう。A semi-cylindrical rebar holding piece 4 with a bottom is vertically welded to the inner peripheral surfaces of the upper and lower ring-shaped members 1 and 1 'at predetermined intervals, and is spaced apart from the upper edge of the upper ring-shaped member 1 by a predetermined distance. Each time, the horizontal pile head engaging portion piece 5 is welded in a cantilever manner so as to extend in the diameter direction of the pile cross section, thus forming the pile head fixing steel temporary fixing jig A. When the pile head anchoring reinforcing bar temporary fixing jig A configured as described above is dropped into the pile head of the SC pile B,
The pile head anchoring piece 5 disposed on the upper ring-shaped member 1 is locked to the pile head, whereby the pile head anchoring rebar temporary fixing jig A is set on the pile head of the SC pile B. . Next, by inserting a pile head fixing reinforcing bar into the bottomed semi-cylindrical reinforcing bar holding piece 4 of the jig A, the reinforcing bar is arranged at a predetermined position, and temporarily fixed to the pile head, and then the jig A is removed.

精度の向上が図られる。[Effect of the Invention] The temporary fixing jig for the pile head anchoring in the SC pile according to the present invention is obtained by projecting the horizontal pile head locking pieces at predetermined intervals from the upper edge of the ring-shaped member as described above. When the ring-shaped member is fitted to the pile head of the SC pile, the temporary fixing jig can be set at a predetermined position. Thereafter, a pile-head anchoring bar is provided on the inner peripheral surface of the ring-shaped member. Since the bottomed semi-cylindrical vertical reinforcing bar holding piece to be inserted is provided, the anchoring reinforcing bar can be held at a predetermined position, and the installation work of the pile head anchoring bar in the SC pile can be performed by one person. As a result, the working efficiency is improved, the process is not delayed, the pitch of the rebar is not disturbed, and the construction accuracy is improved.
