Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a piping fixing device. More specifically, the present invention relates to a pipe fixing device for fixing a pipe to a formwork when constructing a formwork for a concrete wall or the like when a water pipe or the like is installed on a concrete wall or the like of a reinforced steel building.

[Conventional technology]

When installing a water supply pipe or the like on a concrete wall, etc., it is also possible to pour concrete and release the formwork, then scrape away the concrete wall and bury the pipe there. However, since it is not easy to scrape away concrete walls, conventionally pipes were installed during formwork and the pipes were tied and fixed to reinforcing bars or the like. Even if the pipes are tied together in this way, the pipes will move during concrete pouring, especially the open ends of the pipes that are exposed to the wall surface, and not only will it be impossible to install the pipes in the correct position, but the concrete will It was not easy to install faucets etc.

[Problem that the invention attempts to solve]

The present invention solves the above-mentioned drawbacks of the conventional methods.The open end of the pipe can be fixed to the formwork before concrete is poured, so that the pipe does not move during concrete pouring. , which allows piping to be placed accurately in a predetermined position. In addition, an insert member with a special structure is loaded into the open end of the pipe, and this insert member prevents concrete from entering the open end of the pipe, and also makes it easy to remove the insert member after demolding. The present invention provides a piping fixing device that allows easy installation of faucets and connection of pipes.

[Means for solving problems]

The piping fixing device according to the present invention is a device for fixing the pipe to a formwork when piping is installed on a concrete wall, etc., and has a square hole and a screw hole that has a smaller diameter than the square hole and communicates with the square hole. , and having a male thread cut into its outer periphery, is loaded into the open end of the tube. The open end of this tube is brought into contact with the formwork, and
It is characterized in that a screw rod passed through the formwork from the other side of the formwork is screwed into the screw hole of the insert member and fastened with a nut or the like.

[Function of the invention] The present invention involves loading an insert member into the open end of the pipe, abutting the open end against the formwork, and
A screw rod passed through the formwork is screwed into the screw hole of the insert member and tightened with a nut. Then, the formwork is held between the open end of the pipe and the nut, and the open end of the pipe is fixed to the formwork.
In addition, the insert member loaded into the open end of the pipe prevents concrete from entering the open end, and after the formwork is released, this insert member is inserted into the square hole with approximately the same shape as the square hole. It can be easily extracted by inserting and rotating the rotation jig.

〔Example〕

Embodiments of the present invention will now be described with reference to the accompanying drawings.

The drawing shows the case where piping is installed on a concrete wall.
Fig. 1 is a sectional view of the fixed state, Fig. 2 is an exploded perspective view, Fig. 3 is a partially cutaway perspective view of the insert member showing another embodiment, and Fig. 4 is a perspective view of the screw rod showing another embodiment. It is a diagram.

In the present invention, as shown in FIGS. 1 and 2, when a pipe 1 for water supply or the like is installed on a concrete wall, the pipe 1 is fixed to a formwork 2. The pipe 1 is installed before pouring concrete, that is, when constructing the concrete wall formwork, and has a female thread cut into its open end 11, to which a faucet can be attached, although not shown. , it is now possible to connect another tube. Open end 11 of this tube 1
The insert member 3 is loaded in the. The insert member 3 is made of hard vinyl chloride or the like, and has a hexagonal square hole 31 and a screw hole 32 having a smaller diameter than the square hole 31 and communicating with the square hole 31. Further, a male thread 33 is cut on the outer periphery of the insert member 3, and is screwed into the opening end 11 of the tube 1 by applying the threaded hole 32 side to the open end 11 of the tube 1 and rotating it. It is designed to be pulled out when rotated. In this way, the insert member 3 is inserted into the open end 11 of the tube 1.
If it is loaded, concrete will not enter the open end 11 when concrete is poured. Also,
Into the square hole 31 of the loaded insert member 3,
Since a rotation jig (not shown) having substantially the same shape as the square hole 31 is inserted and rotated, it is removed, so that it is easy to attach a faucet or the like thereto after the mold 2 is released. The open end 1 of the tube 1 into which this insert member 3 is screwed and loaded
1 is brought into contact with one side of the formwork 2. The formwork 2 is pre-drilled with through holes 4 in the exact position to fix the open end 11 of the tube 1.
is drilled in advance, and the open end 11 of the tube 1 is brought into contact therewith. On the other hand, attach the screw rod 5 to the formwork 2 from the other side of the formwork 2.
The threaded rod 5 is inserted into the threaded hole 32 of the insert member 3 loaded into the open end 11 to pass through the formwork 2. This screw 5 and nut 6
Screw on and tighten. Then, the formwork 2 is held between the open end 11 of the tube 1 and the nut 6, and the open end 11 of the pipe 1 is fixed to the formwork 2. Note that the nut 6 may be screwed onto the screw rod 5 in advance, or a washer 7 may be installed between the nut 6 and the formwork 2.
may be interposed.

FIG. 3 shows an insert member 3 showing another embodiment.
In this example, the square hole 31 is octagonal. This square hole 31 is for making it easier to rotate the insert member 3 when it is pulled out from the open end 11 of the tube 1, and is not limited to the illustrated shape as long as it is square.

FIG. 4 shows another embodiment of a screw rod 4 having a head 8. When this screw rod 4 is used, the formwork 2 is held between the open end 11 of the tube 1 and the head 8 of the screw rod 4. In addition, head 8
The shape of the nuts 6 and 6 are not limited to those illustrated. Although not shown, it may be shaped like a butterfly, for example.

[Effect of idea]

As described above, according to the present invention, the formwork is held between the open end of the pipe and the nut,
Since the open ends of the pipes are fixed to the formwork, the pipes, especially the open ends, do not move during concrete pouring, and the pipes can be placed accurately at predetermined positions.
In addition, the insert member loaded into the open end of the pipe prevents the concrete member from entering there during concrete pouring, and since this insert member is easy to remove after the mold is released, the pipe It is easy to attach a faucet or connect a pipe to the open end of the pipe, and it is extremely convenient when installing a water pipe or gas pipe to a concrete wall or the like.
