PURPOSE:To reuse parts economically in the construction of foundation by a method in which struts are erectly provided on a base slab, a holder is attached to the struts, reinforcing bars are set on the holder, a formwork is set on the outside of them, concrete is placed into the formwork, and the struts and the holder are removed out. CONSTITUTION:Struts 3 are detachably set on a fixed base slab 2, and a holder 6 is horizontally attached detachably to the upper parts of the struts 3. Reinforcing bars 7a and 7c are supported on the holder, other reinforcing bars are set to assemble them, and a formwork 8 is set on the outside of them. Concrete 10 is placed to a level at which the assembled reinforcing bars 7 can stand by themselves, and the holder is removed out of the struts 3. The struts 3 are removed from the base slab 2, and concrete 10 is again placed. Since the struts 3 and the holder 6 can be removed, they can be repeatedly utilized. |
