定していた。2. Description of the Related Art To make a wall or floor when constructing concrete, there is a method in which a form is provided outside the part corresponding to the wall and the floor, fresh concrete is poured into the form, and the form is removed after it has set. It is being appreciated. Water pipes and gas pipes need to penetrate walls and floors, and if only the above method is used, it will be necessary to make holes after concrete has solidified. However, this work is difficult, so make sure that the fresh concrete does not flow into the expected parts when water pipes and gas pipes are installed.
A cylindrical void 1 made of paper or the like as shown in FIG. 2 is attached to the form 2, and after the concrete 5 is solidified, it is removed to secure a hole for connecting a water pipe or a gas pipe. The void 1 for securing this hole is covered with gum tape 3 etc. so that fresh concrete does not flow in, and some nails 4 are poured before pouring fresh concrete in order to make it easy to remove after concrete 5 has hardened. It was fixed diagonally to the formwork.

In some cases, the nail 4 was pulled out and the void 1 came off the formwork 2. If left as it is, the role of the void 1 for securing the hole cannot be fulfilled. When the void 1 was detached from the form 2, it was necessary to interrupt the pumping of the fresh concrete and attach the void 1 to the form 2 again. At least two workers are required because the place where the concrete is pumped and the place where it is poured are separated, and there is a trouble between the two because the communication does not go smoothly when an accident occurs. There were many things.

定されることになる。Here, one end of the void 11 is pressed against the mold 9 so that the support member 10 is located at a substantially central position, and the void lid 12 is put on the other end of the void 11. The void lid 12 is provided with a hole through which the bolt 14, which is a tightening portion of the support member 10, penetrates. When the void 11 is thus provided between the mold 9 and the void lid 12, and the bolt 14 at the end portion of the support member 10 is tightened with the nut 13, this force is applied in order to the void lid 12 and the void 11.
The void 11 is pressed against the mold 9 and is securely fixed here.

FIG. 3 is a schematic cross-sectional view when a reinforcing material is added to. Void 11
It is necessary to use different lengths depending on the thickness of the floor and walls. If the void 11 is short, no problem will occur even if the void 11 is made of paper, but if the void 11 is long, an accident may occur in which the void 11 is sometimes crushed.
When the fresh concrete is poured, pressure is applied to the void 11 from this periphery toward the center. On the side of the void lid 12 of the void 11, the convex portion 12A of the void lid 12 serves as a support and is not crushed, but the form 9 of the void 11 does not have the support like the convex portion 12A of the void lid. Therefore, when fresh concrete is poured, this pressure is generated by void 1.
In order to prevent crushing by adding to 1, the PVC pipe 17 is inscribed in the void 11 as shown by the broken line, or the void support plate 19 is inserted in the void 11.

ある。However, in the embodiment shown in FIG. 1, the support plate 6 is fixed to the frame 9 by the wood screws 7 with flanges (three in the drawing), and one end of the support member 14 is screwed into this. When the bolt 14 provided at the other end of the support member 14 is tightened with the nut 13, the void 11 is fixed to the mold 9 as described above. The void pressing member 20 shown in FIG.
When a person or a hose comes into contact, the force is transmitted in the order of the void 11, the void lid 12, and the support member 14, but these members are very strong to the machine and are not broken. A force is applied between the mold and the mold 9. Since the support plate 6 and the form 9 are securely fixed by the wood screw 7 with a flange,
The void pressing member 20 does not easily come off from the frame 9 or break even if a person or a hose comes into contact therewith.

If the support member 1 is rotated in the opposite direction from when it was tightened,
0 and the support plate 6 can be removed together from the formwork 9. The void pressing member 20 can be reused except for the void 11.

ある。The void holding member 20 shown in FIG.
It is a little more troublesome to install in or to remove after the ready-mixed concrete hardens compared to the conventional example. However, when the void pressing member 20 comes off while pouring the fresh concrete and the worker does not notice this and the fresh concrete flows into the planned hole portion and hardens as it is, the hole must be made later in the concrete. It will leave such a difficult work. Also, the formwork 2
Compared with the void pressing member 30 of the conventional example in which the pouring is interrupted and the pouring is interrupted and the installation is required again, even if it takes some time for installation and removal, the form 9
It is better to install the void pressing member 30 that does not come off or break, so that the work can be carried out with more peace of mind, and the efficiency is far higher when the overall efficiency is taken into consideration.
