Description

[Detailed description of the invention] (Industrial application field) This invention is for flexible electrical conduits used when bending and standing up flexible electrical conduits installed horizontally on slabs, etc. in concrete buildings. This invention relates to a rising part holder.

(Prior art) Conventionally, flexible electrical conduits P through which indoor electrical wiring and telephone lines are inserted in concrete buildings such as apartment complexes and office buildings are horizontally piped inside slabs F, as shown in Fig. 6. It is raised vertically directly below the embedded box B to which indoor electrical wiring and telephone lines are connected, and is connected to the embedded box B.

As shown in Figure 7, in a concrete building, strut reinforcement Q is arranged horizontally in the slab in a grid pattern, and strut reinforcement S is arranged vertically in the wall or column. The flexible electrical conduit P is piped horizontally along the support beam reinforcement Q, curved vertically at a predetermined position, and its raised portion P' is tied and held along the support support reinforcement S. There is. In such piping, the raised part P' of the flexible conduit P is aligned with the support beam S, so it is necessary to hold the raised part P' in the position shown by the chain line in Figure 7. Start-up section
P′ cannot be maintained and the starting position is limited.

In addition, the embedding box is not always buried in a position close to the strut reinforcement S, and even if it is necessary to bury it so that it is located midway between the adjacent strut reinforcement S, it is necessary to bury the embedment box directly below the embedment box. I couldn't start it up. Therefore, the relative positions of the embedded box and the raised portion are shifted and do not coincide with the knock-out holes of the embedded box. Therefore, as shown by the chain line in Fig. 6, the rising part of the flexible conduit P is
P' is curved into an S-shape and connected to the recessed box B. Generally, the installation height H of the recessed box B is set to around 200 mm from the top surface of the slab F, and within this short raising distance. Not only is S-bending an extremely difficult task, but the S-bended flexible conduit P may buckle and collapse.
There is a risk that subsequent line access may become impossible.

Furthermore, since the support beams Q that make up the slab F are only arranged in a lattice pattern that forms grids of approximately 200 mm square, the space within the grid of the support beams Q is The flexible electrical conduit P could not be set up, and the piping work for the flexible electrical conduit was restricted.

As this kind of conduit support,
There was a flexible pipe rising support device described in 89675, and a piping end fixing device described in Japanese Utility Model Application Publication No. 56-102880.

In the former, a support piece in the form of a leg is bent and erected on a fixed piece that contacts and is fixed to a temporary fixing surface, and a flexible tube that is to be supported in an upright manner is inserted through the support piece. The support tube is fixed in the vertical direction, and the work to hold the upright part of the flexible tube is to fix the support tube to the fixed piece fixed to the temporary concrete frame, and then insert the flexible tube into the support tube. It is necessary to fix the support tube to the fixed piece after fixing or inserting the flexible tube into the support tube in advance, and after fixing the support tube to the fixed piece fixed to the temporary concrete frame, When inserting and fixing a flexible pipe, if the distance between the temporary concrete frame and the support tube fixed to the fixed piece is short, it is difficult to insert and fix the flexible tube into the support tube. , after inserting the flexible tube into the support tube in advance, it is necessary to fix the support tube to the fixed piece. In this case, if the length of the upright part of the flexible tube is long, It is difficult to insert the upright part, and in any case, the work procedure is limited, resulting in poor work efficiency.

The latter consists of a fixture that has a flat part for floor mounting and a sleeve for supporting the base of the rising part of the piping, and a protective tube that can be attached and detached to the upper end of the sleeve. The holding work involves inserting the piping into the sleeve of the fixture fixed to the temporary concrete frame, inserting the piping into the protective pipe, and fixing the protective pipe to the sleeve of the fixture, or inserting the piping into the sleeve of the fixture. After fixing the pipe, it is necessary to insert the pipe into the protective pipe and the sleeve of the fixture, and like the former, it is difficult to insert the rising part of the pipe, and in any case, the work procedure is limited. The problem was that work efficiency was poor.

In view of these drawbacks, the present invention proposes that the lid body may be attached to the holder after the opening of the holder of the holder main body is brought into contact with the upright part of the flexible conduit, or that the lid body may be attached to the holder in advance. After the lid is brought into contact with the upright part of the flexible electrical conduit, the lid may be attached to the opening of the holding part of the holder main body, and the distance between the temporary concrete frame and the holding part and the flexible electrical wire It is an object of the present invention to provide a holder for a flexible electric conduit tube in which the working procedure is not determined by the length of the tube tube tube.

(Structure of the invention) The basic structure of the invention includes a semicircular holding part that has an opening on the side surface for introducing the rising part of the flexible conduit, and a semicircular holding part that supports the holding part and is flexible. a support leg provided at a position that does not interfere with the bending of the flexible conduit;
It consists of a holder main body having a fixing part that fixes the supporting legs to the temporary concrete frame, and a lid body that is attached to the holder and closes the opening.
Then, when the upright portion of the flexible conduit is introduced into the holding portion through the opening and a lid is attached to close the opening, the upright portion is held in a predetermined position.
