上の問題が生じてしまうため、実用的ではなかった。The flutter material used for the horizontal siding material 25 and the vertical siding material 28 is usually 60 m on a side.
m or 50 mm (in the case of round pipe flap material, the outer diameter is 6
0 mm or 50 mm). Therefore, in order to dispose the vertical flap material 28 between the horizontal flap material 25 and the barrier plate portion 12 so as to be in contact with the horizontal flap material 25 and the barrier plate portion 12, the side plate portion 13 and the reinforcing member are provided. The width of the plate portion 15 (the depth from the side surfaces of the side plate portion 13 and the reinforcing plate portion 15 to the back surface 14 of the dam plate portion 12) is 60 mm or 50 m depending on the flap material.
had to be m. Therefore, it is necessary to manufacture two types of molds, the mold having a width of the side plate portion 13 and the reinforcing plate portion 15 of 60 mm and the mold having a width of 50 mm. Further, in order to mold the two types of molds, it is necessary to manufacture two types of molds, which has been a cause of an increase in the manufacturing cost of the molds. Although it is possible to cut the side plate portion 13 and the reinforcing plate portion 15 according to the thickness of the flap, when the reinforcing ribs 17 do not remain on the cut surface, the strength of the side plate portion 13 and the reinforcing plate portion 15 is reduced. It is not practical because it causes functional problems such as deterioration and appearance problems.

m) is prepared in advance. However, when a mold of an odd size other than this is required, veneer plywood that is normally used as a wooden concrete mold may be cut to the required size and added to the mold 10. When the veneer plywood is added, the side plate portion 13 on the side where the veneer plywood is added is unnecessary. In order to cope with such a case, it was necessary to further manufacture and prepare in advance a mold in which the dam plate portion on one side was omitted. Further, similarly, it is necessary to manufacture a mold for this mold, which causes a further increase in the manufacturing cost of the mold. When the side plate portion 13 is no longer needed, the side plate portion 1
Although it is conceivable to cut 3 from the root, if the reinforcing rib 17 does not remain on the cut surface, a functional problem such as a decrease in the strength of the weir plate portion 12 and a cosmetic problem will occur. It wasn't practical.

The lower end of the form 10 is positioned and fixed with nails or the like on the floor flap 61 which is level-adjusted and fixed to the 0th surface. However, if the reinforcing plate portion 15 is cut from the root, if the reinforcing rib 17 does not remain on the cut surface, a functional problem such as a decrease in strength of the dam plate portion 12 and a problem in appearance occur.

い。Further, it is not always necessary to previously provide an insertion hole in the barrier plate portion. The insertion hole may be drilled at the site after determining the position to insert the separator at the site of concrete pouring. At this time, since the dam plate portion is hollow, the insertion holes need only be formed on both surfaces and can be easily performed. Further, since the dam plate portion is made of plastic, it is easy to form the insertion hole. In addition, when the insertion hole of the weir plate is to be drilled on site, the tip of the drill for drilling should be located between the reinforcing ribs to facilitate opening of the insertion hole without lateral deviation. A groove for a drill guide may be provided in the vertical direction on the surface of the plate portion.

Since they are formed with a space of 10 mm, even if the side plate is cut in the longitudinal direction at 10 mm from the side surface of the side plate, the functional problem such as the strength of the side plate is reduced, and the appearance. It does not cause the above problem. Therefore, the concrete formwork of the present invention can be applied without problems even when using a vertical flap material having a side length of 50 mm by cutting the dam plate portion in the vertical direction at a position 10 mm from the side surface of the side plate portion.

Is the same as the thickness of the weir plate, so even if the side plate is cut at the root, functional problems such as a decrease in the strength of the weir plate and appearance problems will occur. Never. Therefore, when the side plate portion is unnecessary, the side plate portion can be cut at the root. Further, if a reinforcing plate portion parallel to the side plate portion is provided on the back surface of the concrete casting surface of the dam plate portion, the durability and pressure resistance of the concrete formwork can be improved. If the concrete formwork of the present invention is transparent or translucent, it is 10 mm from the side surface.
When cutting the side plate portion or the reinforcing plate portion or cutting the side plate portion or the reinforcing plate portion from the root, it becomes easy to cut just before the reinforcing rib.
