Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a jig for a flexible pipe guide used for piping a flexible pipe used for flexible electric wire pipe construction, and is suitable mainly for use in concrete burying work. Flexible tube guide jig.

[0002]

2. Description of the Related Art For flexible electric wire pipe work associated with concrete placing work, for example, a flexible pipe made of synthetic resin is laid between double reinforcements in a floor slab, and an electric wire is placed inside the flexible pipe. Wiring.

Conventionally, this kind of work is performed manually by a worker, and a flexible pipe is manually fed between the double bars during piping.

On the other hand, as a jig for pulling in a flexible pipe, a connecting jig for indexing to a flexible pipe described in Japanese Utility Model Publication No. 4-7426 and a retractor for a flexible pipe described in Japanese Utility Model Publication No. 3-8855. There is. These jigs are used when pulling the flexible pipe into the pipe that has been previously piped, and are mainly used for gas piping work. That is, the conventional retracting jig is used when retracting the metal flexible tube into the inside of the plastic sheath tube.

[0005]

In the work of piping a flexible pipe made of synthetic resin between the double reinforcements in the floor slab, the work of manually feeding the flexible pipe in a straight line is extremely troublesome. Was becoming. That is, the flexible tube made of synthetic resin is wrapped around during packaging and is cut to an appropriate length when used. Therefore, at the time of use, it is used in a state in which this winding habit cannot be taken. In this way, if you try to feed straight with the curl attached, you can not easily feed like a metal pipe or PVC pipe, and you have to work while the flexible pipe is caught by the double streak. I don't get it. Therefore, the worker is forced to work while moving in a middle waist position, and usually 2 to 3 m to 15 m
The work of piping more than m was difficult work.

Further, in the work of passing the flexible tube through the reinforcing bar of the body wall, it is a work in a place where it is difficult to reach, and even the wiring for a short distance is more difficult work.

On the other hand, in all of the jigs for retracting a flexible tube that have been proposed in the past, since the flexible tube is retracted by using a pulling tool such as a wire, it is possible to insert the flexible tube into a pre-arranged tube like a sheath tube. Even if it is suitable for pulling in a flexible tube, it is not suitable for the work of linearly piping a flexible tube made of synthetic resin between the double reinforcements in the floor slab, and the problems of the conventional manual feeding work It does not resolve.

Therefore, the present invention was created in order to solve the above-mentioned problems. Even if a flexible tube made of synthetic resin having a curl is used, straight line feeding can be performed very easily. In particular, an object of the present invention is to provide a jig for a flexible pipe guide that can simplify the flexible conduit work associated with concrete burying work.

[0009]

In order to achieve the above object, a first means of the present invention is a flexible body having a rod-shaped guide body and a connecting body for connecting a flexible tube to a distal end of the guide body. In the pipe guiding jig, the connecting body is provided with a grasping opening for grasping the side surface of the end portion of the flexible tube.

The connecting means of the second means is provided with a plurality of grasping openings which selectively correspond to flexible tubes having different diameters.

Further, the guide body according to the third means is such that a joint is provided at the tip end portion and extension guide bodies for extending the entire length of the guide body are sequentially connectable.

Further, the connecting body is provided with an end cover for covering a plurality of grasping openings as a fourth means for solving the problem.

[0013]

That is, according to the first means of the present invention, the guide body is advanced to the piping position of the flexible tube in advance. Then, the flexible tube connected to the end of the guide body is pulled out through the guide body and is piped at a predetermined position.

In the second means, a plurality of grasping portions correspond to a plurality of different diameter pipes.

In the third means, the length of the guide body is extended to cope with long span wiring work, and the connecting portion of the guide body is removed to facilitate transportation and storage.

Further, the fourth means is that the end cover protects the end of the flexible tube connected to the connecting body, so that when the flexible tube is pulled out through the guide body, the end of the flexible tube is pulled out. It prevents the vehicle from colliding with the surroundings.

[0017]

Embodiments of the present invention will be described in detail below with reference to the drawings.

The main structure of the present invention is a rod-shaped guide body 1.
And a connecting body 2 for connecting the flexible tube P to the end of the guide body 1.
It consists of and.

The guide body 1 is mainly intended to use a synthetic resin (FRP) material. This is because it is lightweight and has a high elastic limit, so it is easy to carry, and even if it is subjected to forced deformation, it is easily restored to a straight line shape. And
A joint 1A is provided at the tip of the guide body 1. Further, the extension guide body 3 for extending the guide body 1 is sequentially connected to the joint 1A (see FIG. 2). Joint 1 shown in the figure
Although A has a screw shape, it may be changed to a conventionally known joint. Further, a sharp head 4 is provided at the joint 1A of the guide body 1 or at the tip of the earliest extension guide body 3,
The insertion work of the guide body 1 is facilitated.

The connector 2 is provided with a grasping opening 2A for grasping the side surface of the end portion of the flexible tube P. The grasping portion 2A is provided in a stepped shape so as to correspond to the end side surface of the flexible tube P having a different diameter. The grasping port portion 2A in the illustrated example is formed of an elastic synthetic resin material, a metal material, or the like into a substantially C-shaped cross section, and forcibly grasps the flexible tube P by its own elastic force. At this time, the grasping opening 2A is formed in a sharp shape from the tip so as to correspond to three kinds of diameters of small, medium and large, and the resistance during movement is minimized (see FIG. 5). The type of diameter can be set arbitrarily. A rib 2B that prevents the flexible tube P from being displaced is further formed inside each grasping opening 2A. FIG. 3 is a cross-sectional view showing a state in which the end portion of the flexible tube P is inserted into the grasping opening portion 2A and the side surface of the end portion of the flexible tube P is grasped by the grasping opening portion 2A. As described above, when the flexible tube P is connected to the grasping port 2A, the flexible tube P is deformed, and a part of the side surface projects.

Therefore, the protruding end can be protected by providing the connecting body 2 with the end cover 5 that covers the grasping opening 2A (see FIG. 4). The end cover 5 shown in the figure has large, medium, and small grasping openings 2A formed in steps.
Has a substantially C-shaped cross section, and the opening of the grasping opening 2A is fitted into the grasping opening 2A.
Further, in the figure, the entire end cover 5 is compactly formed by forming only the end cover 5 on which the large-diameter grasping opening 2A is formed, in the shape of a projecting piece (see FIG. 5).

The use of the jig of the present invention is as follows. That is, the guide body 1 is inserted between the double streaks from a predetermined position where piping is desired. Next, the flexible tube P is connected to the connector 2. Then, the guide body 1 is pulled out from the end point of the extending pipe, and the flexible pipe P is pulled out. Finally, the flexible tube P is removed from the connection body 2 and the flexible tube P is connected to a box or the like.

[0023]

The present invention achieves the original object by being configured as described above.

That is, according to claim 1 and claim 2,
The guide body 1 guides the pipe of the flexible tube P, and even if the flexible tube is made of synthetic resin having a curl, linear feeding can be performed very easily.

According to the third aspect, the jig of the present invention can be made compact, which is convenient for carrying and storing.

Further, in the present invention, since the end portion cover 5 protects the end portion of the flexible tube P, smoother piping work of the flexible tube P can be performed, and moreover, the end portion of the flexible tube P can be secured. It has the effect of preventing deformation.

As described above, according to the present invention, even a flexible tube made of synthetic resin having a curl can be extremely easily fed straight, and is particularly suitable for concrete pouring work. It has various industrially beneficial effects such as being able to simplify flexible conduit work.
