Claims

[Scope of Claim for Utility Model Registration] 1. A long rectangular formwork that is assembled along the outer surface of a structure during concrete pouring, and one longitudinal end of which is hinged so that it can rotate relative to the other. The first and second face plates are provided with first and second face plates that are pivotally connected, and the first and second face plates have a box-shaped edge plate projecting from the outer end of the face plate in the longitudinal direction, and a box-shaped edge plate at both ends of the face plate in the short direction. A side plate that projects in a shape and has mutually overlapping tips, and a reinforcement that stands in parallel with the side plate within the face plate and has mutually overlapping tips and a locking mechanism provided in this overlapping portion. a plate, the first and second face plates are rotated and bent so as to match the folding surface of the structure, and the reinforcing plates are moved to an arbitrary bending position using a locking mechanism provided at the overlapping part of the reinforcing plates. A bendable formwork characterized in that the bent state of the first and second face plates is maintained while the first and second face plates are locked. 2. The reinforcing plate locking mechanism includes a bolt protruding and fixed from the overlapping part of one reinforcing plate, and an arcuate hole drilled in the overlapping part of the other reinforcing plate to guide the bolt into engagement. The ends of the overlapped portions of each of the reinforcing plates and each of the outer plates are arranged so as not to impede bending of the first and second face plates.
The bendable formwork according to claim 1, which is characterized by having a tapered notch end diagonally upward from the pivoting portion of the second face plate. 3 The locking mechanism of the reinforcing plate includes bolt holes drilled in the overlapping part of one reinforcing plate, and circular arc holes drilled in the overlapping part of the other reinforcing plate so as to correspond to and communicate with the bolt holes. and a hole, the ends of the overlapping parts of the reinforcing plates and the outer plates being diagonally above the pivoting parts of the first and second face plates so as not to impede the bending of the first and second face plates. A utility model registration according to claim 1, wherein a bolt is tightened through the bolt hole and the circular arc hole while the reinforcing plates are locked to each other at an arbitrary bending position. bendable formwork.
