Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a tool used for conduit piping at a construction site.

[0002]

[Prior art]

 Conventionally, it is common practice to embed a flexible conduit made of synthetic resin on the floor of a building or the like in order to wire a communication line or a power line. In this case, terminal boxes are placed at appropriate intervals when reinforcing bars are laid on the floor, etc., and after the conduit is laid around the reinforcing bars between each terminal box, concrete is poured. You.

[0003]

[Problems to be solved by the invention]

 It is not easy to arrange the flexible conduit as it is through the reinforcing bars, and it is also possible to improve the workability by disposing the end of the conduit with one end of the glass fiber rod attached. As a result, there were inconveniences that the joining work took time, and that the end of the conduit was easily caught by the reinforcing steel during the installation, resulting in poor workability.

[0004] An object of the present invention is to provide a tool for easily and quickly arranging a flexible conduit by sewing between reinforcing bars.

[0005]

[Means for Solving the Problems]

 In the present invention, a tubular body having an inner diameter adapted to the outer diameter of a conduit and having a part of a side wall cut out to fit the conduit is attached to one end of a long rod. The above object is achieved by providing a flange on the inner surface which engages with an annular groove formed on the peripheral surface of the conduit tube. A metal cap is fitted to one end of the long rod made of an elastic material such as the glass fiber rod, and a thread provided at one end of the metal cap is formed into a triangular pyramid shape using a rigid material such as a light alloy. The above object can also be achieved by screwing onto the top of the formed cylindrical body.

[0006]

[Embodiment of the invention]

 Referring to the drawings, an embodiment of the present invention will be described. In FIGS. 1 and 2, reference numeral 1 denotes an elastic long rod made of glass fiber or the like, and 2 denotes a light rod attached to one end of the rod 1. Shows a strong cylinder made of a rigid material such as an alloy. The cylindrical body 2 has an inner diameter D adapted to the outer diameter of the wire tube 3, and a part of the side wall 2a is cut off 2b so that the wire tube 3 can be inserted into the cylindrical body 2 from the side. did. The conduit tube 3 is made of synthetic resin having an annular groove 3a and a ridge 3b formed on the outer periphery. When this is fitted into the cylindrical body 2, it fits into the groove 3a and engages. The flange 4 is provided on the inner surface of the cylindrical body 2.

The length of the rod 1 is arbitrary and is determined according to the site of the plumbing work. Further, a triangular pyramid-shaped top 2c is formed in the cylindrical body 2 so that the cylindrical body 2 is less likely to be caught by a reinforcing bar or the like. In order to connect the top 2c to the rod 1, a light metal alloy cap 5 is fitted to one end of the rod 1 by caulking or the like, and a screw 5a provided at one end of the metal cap 5 is connected to the cylinder. It was screwed on the top 2c of the body 2.

The tool of the present invention fits the flange 4 of the cylindrical body 2 by engaging the concave groove 3 a of the conduit tube 3 as shown in FIG. 3, and attaches the rod 1 to the terminal box 6 as shown in FIG. At the construction site where the installation has been completed, the leading end is guided to a predetermined position through the space between the reinforcing bars 7, the conduit 3 is cut to an appropriate length, and both ends are fixed to the terminal box 6. By doing so, piping of the conduit tube 3 is performed, and since the attachment and detachment of the conduit tube 3 and the tubular body 2 are simple, piping work can be performed efficiently.

[0009]

[Effect of the invention]

 As described above, according to the present invention, a part of the side wall of the cylindrical body attached to one end of the long rod is cut off, and the inner surface of the cylindrical body is provided with a flange that engages with the annular groove of the conduit tube. As a result, the conduit can be easily attached to a rod, and the rod can be passed through the inside of a reinforcing bar such as a steel cage to efficiently perform flexible conduit piping, and the structure is simple and inexpensive. There is an effect that can be achieved, and by adopting the configuration of claim 2, an effect that the pipe can be smoothly piped is obtained.
