作業が困難でわる。<Conventional technology> Generally, when producing a U-shaped product for use in waterways, etc. using the pour molding method, the inner formwork, which has an inverted concave shape, is fixed downward and then cast into a comfleet tray. When removing the cured product from the formwork, a side plate that is hinged to the formwork base is used. The end plate is tilted and opened outward to remove the product from the mold.
Problems to be Solved by the Invention〉 In the case of relatively small-scale drainage channel products, conventional mold removal and one assembly is sufficient, but in the case of large-meter products such as irrigation channels with an IT value of several hundred to nine, the side plates of the formwork, The end plate is also a heavy covering, and the conventional method of stopping the mold in a tilted position and removing the entire product from the mold is dangerous, and requires cleaning the inner surface of the mold and applying mold release agent while it is half open. It's difficult and bad.

そのため側板、置板？全開倒置すると脱型に必要なスペ
ースが広く要するなとの欠点がｂる。Therefore, is it a side board or a placing board? When fully opened and upside down, the drawback is that a large space is required for demolding.

Is it possible to open and close the end plate and side plate due to dangerous slopes? This makes it easier to remove the product from the mold, clean the mold, and assemble the fabric, and also makes it easier to adjust the width and height of the mold according to the product design. This makes it possible to mold multiple types of products with different shapes using a single set of molds.

る。When removing the poured concrete product from the formwork after it has hardened, the left and right side metal plates fastened to both sides of the end plates are horizontally turned outward, and then the metal parts are removed from the formwork via the rails on the base of the formwork body. The moving end sheet metal is moved away, and the vacuum mat is adsorbed to the top opening to remove the product from the mold upward. In this case, as long as there is no problem in demolding the product, the end plate can be moved only on one side.Also, the lower end of the vertical wall of the inner formwork has a ridge or wall thickness (kB) depending on the product system. 4 extravagant dimensions aI! Equipped with lJ matsuri formwork, the horizontal part of the inner formwork is provided with a connecting part of the bottom width adjustable firefly formwork according to the width, and the formwork of 7nzorL is attached to the vine that can be used by Kinjin. Saichi? Products with different widths? <Example> 1 is provided with a rail 23 on the base of the formwork body for moving the movement i#ke 3 outward via 22 wheels. On the opposite side, the other fixed end plate 2 is fixed to the formwork main body base 1 and is received by the inner formwork forming the inner surface of the OMμ waterway.
The lower part Vc in the vertical direction without a T-shape has a dimension adjustment firefly form frame 20 that adjusts the height of the fixed end plate 2. Moving 6301+1 Underneath the inner formwork 7. ) It is fixed with NC bolts 21.

After finishing the top surface filled with concrete and poured in step 1, cover it with a sheet to prevent moisture from evaporating from the top surface of the formwork during curing and hardening.0 After curing and hardening, remove the product from the mold. To do this, first open the latches 18 on the latches that have been tightened and fixed on both sides, and then tighten and secure both sides &4.

4', and then loosen the connecting bolt 15Ja of the formwork joint 13' of the adjustment mold 2 and 13, and tighten the bottom width from the upper side. ] After removing the connecting bolt 15 after using a rope to prevent the f2 formwork 13 from downgrading, the inner formwork movement stopper 26 is set to PF! When the movable end plate 3 is moved to the right side, the inner formwork also moves as a unit as shown in Figure 9 of the VC, so the bottom width adjustment formwork 13 is located outside the bottom area and inside the left side. Since the formwork 6 will be hanging in the air, it must be immediately removed and changed.The left side of the VC wide bottom width adjustment formwork 13 is temporarily tightened to the bottom mounting table 14 of the fixed internal formwork while fishing with a rope from above. As shown in Fig. 5, all the movable end plates VC'il are moved to the left side, placed on the bottom mounting table 14, and connected bolts are all passed through the formwork joints 13' and fixed as in the sixth case.

For this reason, it is fixed with a moving stopper 26.

As shown in Figure 5, side products used in the waterway construction method in which only the bottom part is poured into dusty concrete IJ - can be molded at the construction site, or as shown in Figure 16, only one side can be conveniently used to form an L-shaped f. It is also possible to perform molding by arranging the molding size adjustment formwork 20 on the left and right sides for molding a small wall metal mold or for molding different products at the same time on the left and right sides. Since the frame can be freely changed and applied without changing its cost and purpose, the present invention is advantageous in that it is possible to avoid dangerous damage to the gables and side walls when assembling and removing the large formwork into which the lid is placed.
