Claims

[Claims for Utility Model Registration] 1. A formwork body consisting of plywood cut to predetermined dimensions, a plurality of bar ribs fixed to the outer surface of the plywood so as not to hinder the bending of the plywood, and A formwork comprising a plurality of shape retaining fittings attached to the bar ribs so that the formwork surface of the formwork main body maintains a predetermined curved shape. 2. Parts of the side plate part and the outer plate part are cut out at multiple locations in the longitudinal direction of the longitudinal section of the longitudinal section consisting of the inner plate part, the side plate part, and the outer plate part, and the outer plate part is bent. The main body of the metal fitting has elongated holes on both sides of the notch of the part and the inner plate part, and a connecting plate that is attached to the elongated holes of the outer plate part and connects the outer plate parts together. Shape retaining metal fittings for formwork.
