It is possible to easily form a reinforced concrete column that includes a pair of formwork and column members. In addition, it is possible for even an unskilled person to easily form the column main bar, the band bar, and the form, and the workability is improved. The reinforced concrete formwork / column member in which a part of the strip is projected as a projecting portion can be easily pre-cast at the factory, and thus can be provided at low cost. (B) According to any one of claims 2 to 4, when the cross-sectional shape of the formwork / pillar member is a plate shape such as an elongated rectangle or a hexagon including two long parallel sides, the formwork / pillar member is formed. Forming a form when precasting a member, driving concrete,
Molding work such as mold removal becomes easy. (C) When the cross-sectional shape of the formwork / pillar member is L-shaped as described in claim 6, the pillar formwork can be formed by a pair of formwork / pillar members, and the number of joints is reduced. The work of holding the frame / column member in a predetermined position is also simplified. (D) According to the seventh aspect, the invention can be applied to the construction of a wide reinforced concrete column or a high-strength column. (E) According to the eighth aspect, it is possible to easily and surely connect the lower frame member and the upper member of the frame / column member. (F) According to the tenth to thirteenth aspects, at least a pair of formwork / pillar members are erected, and only one of the formwork / pillar members has a projecting portion of the band bar and the other formwork / pillar member has a band. Since the projecting portion of the streak forms a lap joint, the work of forming the formwork becomes very easy, and the work of removing the formwork becomes unnecessary, so the workability is greatly improved. (G) Since the formwork and pillar member of the present invention can be precast molded in a concrete factory, the surface of the pillar can be finished smoothly without causing defects on the surface thereof.
