を打殺し、埋め戻しを行なう。Next, as shown in FIG. 3, a PC foundation beam 4 is erected in the center between the base PC disposable forms 2. An upper hinged metal fitting 4a is embedded inside the PCI foundation beam 4. Further, a leveling convex portion 4b is protruded from the lower side of the PC foundation beam 4, and is shaped to form a gap with the sacrificial concrete 1. Incidentally, a sheaco star 4C is formed at the end of the PC foundation beam 4 located at the corner with the adjacent PC foundation beam. (See Figure 15) When the erection of the PC foundation beam 4 is completed, as shown in Figure 4, the post-cast concrete 5 is placed between the base PC disposable forms 2.
Kill it and backfill.
第６図は杭基礎の実施例を示すもので、基礎杭６の頭部
