ただめ型枠処理に手間がかかる。[Problems to be Solved by the Invention] When the former column formwork and column rebar are individually preassembled, it takes significantly more labor than when the column formwork and column rebar are preassembled at the same time. Since it is necessary to push up the hoop muscles for the pressure welding work of the reinforcing bars, it is troublesome. In the latter case, since the columnar bar is pressure-welded from the opening provided in the column formwork, the formwork is partially burned and the dead formwork process is troublesome.
