[Conventional technology]

Generally, when constructing a concrete wall, a formwork is made by combining plywood boards. Fresh concrete is poured here to construct the walls. The structure of this formwork is shown in Figure 7. As shown in FIG. ..., 3b... are attached to form a space, and the tip of separator 1 that passes through this space. The home tie 4 is screwed together and fixed, and the pipe 5 is further arranged in a grid pattern on the outside of the home tie 4. Fix the pipe 5 with the pipe holding washer 6 and nut 7 of the home tie 4, and place it vertically and horizontally. It has a structure in which plates 3a and 3b are connected.

0003 When assembling this formwork, first assemble one vertical recess 8 of the formwork, then The return walls 9 facing this are assembled one by one from the lower stage side. This return wall The conventional method for assembling the housing is to assemble the lower sheath plate 3a as shown in Fig. 6. After fixing with the tie 4, the upper weir plate 3b is stacked and assembled on top of this. child In the case of Hold it and place it horizontally on top of the lower weir plate 3a, with the inside of the plywood board 2 facing each other. While touching the tip of the separator 1 that protrudes horizontally from the vertical groove 8, use a mallet to remove the plywood board. Tap the outside of the plywood board 2 to make a mark on the inside of the plywood board 2.

0004 After this, remove plywood board 2, drill a hole at the marked position, and then lower it again. Hold it by hand and stack it on top of the weir plate 3a on the step side, and insert the tip of the separator 1 into the drill hole. 10, and the home tie 4 is screwed and fixed therein. In order like this Next, after fixing the entire surface with home ties 4, place the pipes 5 on the outside of the weir plates 3a and 3b. Arrange them in a row and fix the pipes 5 with the pipe holding washers 6 and nuts 7 of the home ties 4. The formwork shown in FIG. 7 was assembled by connecting the upper, lower, left and right weir plates 3a and 3b.
