Description of the Related Art Conventionally, when forming a haunch part in the work of forming a method frame of this type, the haunch formwork is joined from the outside of the vertical and horizontal formwork at the intersection of the vertical formwork and the horizontal formwork. It is widely known to form a triangular haunch form part by doing so. As a method of connecting the haunch formwork to the vertical and horizontal formwork, a method of joining both ends of the haunch formwork along a vertical formwork and a horizontal formwork with a binding tool or an end part of the haunch formwork There is known a method of inserting and fixing in a mesh of a vertical formwork and a horizontal formwork. However, these methods have a problem in workability that not only is time-consuming to join them, but also requires a high degree of skill to fix the haunch formwork to the vertical and horizontal formwork at an accurate angle. . Furthermore, since the legal frame structure formed by this method is cut off by the vertical and horizontal formwork remaining between the haunch portion and the vertical and horizontal legal frame portions, it is likely to be peeled off or corroded from the haunch portion. There were some difficulties in strength. Also, in combination with the work on the inclined surface, in addition to the work of connecting the vertical and horizontal formwork to each other at the intersection point on the main body side, the troublesome work of connecting the form of the haunch is added. Therefore, the burden on the worker was large.

According to the present invention, there is provided a mesh form frame main body composed of a pair of mesh form mold plates opposed to each other, which are held at regular intervals by a spacing member, and an end of the mesh form frame plate. And a haunch formwork rotatably connected to the part to form a formwork unit for forming a legal form. The free end side of the haunch formwork is joined to the haunch formwork of another formwork body. It is characterized in that it is configured such that an intersection portion of the vertical and horizontal form frames and a haunch portion are formed at the same time by connecting to the end portion on the non-open side. If the haunch formwork is connected to the opposite end portions of the mesh form plates that form the form body, the work of arranging the formwork units with other formwork units becomes simple. Further, the haunch formwork is approximately 13 times larger than the mesh formwork plate.
At least one of the connecting portions can be provided with a stopper that stops in a state of being opened 5 degrees.
