Description of the Related Art In concrete work, the assembling of a form as a casting mold for concrete is the most important work, and the quality of the assembling of the form is directly related to concrete dimensions, quality and accuracy. Conventionally, wooden panels, metal panels, and plastic panels are generally used for formwork panels used in concrete casting. When connecting linearly on the same plane, four panels of the panel are used. Butted with nails or clips. And when connecting formwork panels,
In order to prevent panel wear, it is important to minimize cutting and chipping. Therefore, in the corner, it is often necessary to form the form on site.

[0003] Fig. 12 shows the connection with the plywood at the corner.
The side wall plate 4 of the other panel 1a is abutted at right angles to the surface 3 which is the concrete casting surface of the above, and the joint is fixed with the vertical plate 5, and the adjacent panel arranged in a straight line is connected with the clip 7 with the clip 7. It is fixed. In addition, since the panels cannot be directly connected at the corner on the inner corner side, a pier 10 is struck on a plywood 9 having a predetermined width to form an inner form, to which the panels 1, 1a and the like are connected.

[0004]

As described above, the formwork in the corner needs to be specially manufactured on the site based on the processing drawings. The production of the formwork must be processed to exact dimensions in consideration of the finish and requires skill. In addition, there is a problem that it takes time and effort to manufacture and assemble the formwork and the work efficiency is poor. In particular, it is not something that anyone with skill can manufacture to prevent twisting and distortion. Further, since the formwork having a special size manufactured on site cannot be reused, a large amount of waste material is generated. This has the problem of wasting resources and destroying the natural environment.

As described above, the concave portions 27 and 29 are formed on the outer surfaces of the connecting plates 19 and 20 to form an uneven surface, so that deformation at the time of molding is prevented, and at the time of connection with the concrete panel, sealing at the edge portion is performed. The surface 30 adheres. In addition, since the outer surface is crimped on the contact surface 31 at the time of connection, the overall sealing performance is further improved.

The size of each of the recesses can be arbitrarily determined, and may be appropriately determined in consideration of the material and size of the concrete panel. Further, each of the concave portions can be formed in a closed shape on the opening side. In this case, the four sides of each recess are closed, and the sealing surfaces 30 are formed parallel to the respective edges of the face plates 15 and 17 and the opening 25. Further, in the above-described embodiment, the pin insertion hole 33 is formed in the recess 29, but the pin insertion hole 33 may be formed as a continuous contact surface 31 without forming the recess 29, and may be formed directly in the contact surface 31. Further, the entire surface may be a smooth surface similarly to the face plates 15 and 17 without forming recesses on the outer surfaces of the connection plates 19 and 20. In the above embodiment, the face plates 15, 17
Are described at right angles, but the invention is not necessarily limited to the case of right angles, and the angle of connection can be changed according to the application.
