BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an architectural formwork (including a formwork for civil engineering work) used at a corner portion in concrete casting work or the like, and more particularly to an integrally molded product made of synthetic resin. The present invention relates to a formed corner mold.

2. Description of the Related Art Generally, when a concrete wall having a corner is cast, a method of assembling two molds in accordance with the angle of the corner is often employed to surround the corner. However, it is very complicated and time-consuming. Also, the two formwork elements are connected via a hinge-like rotating connection mechanism,
There is an example in which the left and right form elements are rotated in accordance with the angle of the corner of the concrete wall to be constructed, and are fixed by tightening with bolts and nuts.

However, the formwork elements constituting the conventional formwork of which the angle can be adjusted are made of hard and thick wood plywood or steel plate as a face plate, and flanges (including square members) are formed from the peripheral edge thereof. ) And ribs (including square members). Therefore, the weight is quite large and it is not always easy to handle, especially for wooden items, such as weight increase due to water absorption and early deterioration due to repeated water absorption and drying.
There was also a problem in durability. In addition, since the surface layer of the hardened concrete adheres to the steel plate or the wooden board, not only irregularities are generated on the concrete surface after removing the formwork, but also the concrete attached to the formwork surface must be removed before the next use. No. Although some attempts have been made to extrude or draw aluminum materials into sections with a “harmonic” shape in order to reduce the weight, extrusion or pulling of large-sized deformed structural materials such as formwork has been attempted. It is not easy to remove it, and if this is done, the manufacturing cost will rise. Further, aluminum has an affinity for concrete, like steel and wood, so that the problem that hardened concrete adheres to the surface of the aluminum formwork remains unsolved. In addition, combining two separately formed molds via a rotary connection mechanism also complicates the structure and causes an increase in cost.

The face plate of the corner mold according to the present invention is formed by a honeycomb structure having one surface formed by a flat surface and the other surface formed by a large number of concave holes separated by partition walls or a similar structure. As a result, it is strong and durable despite its light weight, making it easy to transport, assemble, and disassemble the formwork in concrete casting work. In addition, since the synthetic resin face plate has good releasability of concrete, a beautiful concrete surface can be formed, and the conventional extra work of peeling off the adhered concrete is not required. In particular, in the present invention, a groove having a V-shaped cross section is formed on the surface of the face plate provided with the concave hole so that the face plate can be bent at a substantially right angle from an intermediate portion toward the surface having the concave hole. The formwork can be easily bent through the V-shaped groove, whereby the corner portion can be easily surrounded, and two separately formed formworks as in the prior art can be connected to each other via a rotary connection mechanism. This is an advantage that it can be provided at a very low cost because it is not formed by connecting and combining components, but is formed by an integrally molded product made of a synthetic resin.
