(Conventional Technique #J) In order to mass-produce on-site concrete pouring, metal formwork is increasingly being used. The metal formwork is
Generally speaking, when forming a wall, for example, it is made up of integral formwork panels with a predetermined space between the inside and outside, and is not assembled from miscellaneous templates like wooden formwork.
The surface of the formed structure is smooth, and not only does it require no finishing as the concrete is poured, but the formwork can be easily assembled and removed, resulting in significant savings in labor costs.

As an alternative to the conventional integral panels of metal formwork described above, foldable formwork panels are proposed in US Pat. No. 2,544,297.

Also, a panel made of composite material instead of metal has been proposed in US Pat. No. 4,030,694.

In addition, the American economy formwork company is
No. 69,501 proposes a new metal formwork configuration.

The purpose is to facilitate the assembly of metal formwork panels so as not to cause damage.

(Problem to be solved by the invention! [) However, all of the above-mentioned conventional metal formwork panels utilize the smooth surface of iron plates or other flat plates. Since it is made from individual iron plates, in order to give it the strength to support its own weight, the iron plate must be thicker than a certain level, and many reinforcing ribs must be placed in cross-width contact with the inner surface of the iron plate.

Therefore, the weight of the panel itself increases, making it difficult to assemble the formwork, and the conventional welding structure described above also requires cutting or gathering the area, shape, and size of the panel to expand, reduce, or deform it. The disadvantage is that it reduces the adaptability of

In addition, in order to assemble formwork panels with a large area, the edges between each unit must be held with special fastening fittings, and the units of assembled formwork panels must be positioned on the same plane. There are also drawbacks such as the need to use many tools to adjust the position of each unit.

In view of the above, it is an object of the present invention to provide a metal formwork panel structure that can constitute a formwork panel even with thin iron plates or other metal plates.

Another object of the present invention is to improve the adaptability of metal formwork panels in design and other locations.
