Claims

[Scope of utility model registration request]

A single metal plate is cut out to create front, rear, and
In a formwork device in which each of the right side walls is bent and formed upright through a folding line, reinforcing parts extending horizontally are arranged and fixed on the outer surface of each of the side walls, and each of these Both ends of the reinforcing part are crossed so as to overlap with the ends of adjacent reinforcing parts, and at this crossing part, a vertical through hole is provided at each end of the reinforcing part, and a tip can be inserted freely into the through hole. a fixing pin having a tapered portion and a base end having an equal diameter shaft portion, and when fitting the equal diameter shaft portion of the fixing pin into the vertical through hole, the front, rear, left, and right side walls. is tightened and fixed in a predetermined assembled state, and when the tapered portion of the fixing pin is fitted into the vertical through hole, the front, rear, left, and right side walls are bent in the direction of expansion due to bending reaction force. A formwork device for concrete molded products, characterized in that the formwork opening is expanded by bending the formwork.
