The suspending portion 32 may have any structure for suspending the wiring and piping material. For example, as shown in FIG. 7, the tip is formed in a hook shape, and the wiring and piping material is provided inside. It may be held.

Next, a method of wiring and piping of wiring and piping materials by the wiring and piping device according to the second aspect will be described.

FIGS. 8 to 10 are side views showing one example of a method of wiring and piping of wiring and piping material by the wiring and piping apparatus according to the second aspect. First, as shown in FIG. The retracting tool 20 is inserted from one end of the tube 10 to the attached tube 10 while the engaging portion 21 is engaged with the engaged portion 11 of the rail body 12, and is inserted to the other end. Next, as shown in FIG. 9, the wiring / pipe X is connected to the connecting portion 22 of the retracting tool 20 at the other end of the pipe 10. Then, as shown in FIG. 10, the wiring / piping material X is drawn into the pipe by pulling the retracting tool 20 back to one end of the pipe 10, and the wiring / piping material X is inserted into the pipe.
Can be wired and piped. By repeating this operation, a plurality of wiring and piping materials can be wired and piped in the pipe.

FIGS. 11 to 13 are side views showing another example of the wiring and piping method of the wiring and piping material by the wiring and piping device according to the second aspect. Is used. First, as shown in FIG. 11, a spare rope 40 is previously connected to the connecting portion 22 of the retracting device 20, and the hooking portion 21 is hooked on the hooked portion 11 of the rail body 12 of the rail-attached tube 10, and the pull-in is performed. Tool 20
Is inserted from one end of the tube 10 to the other end. Next, as shown in FIG. 12, the spare rope 40 is detached from the connecting portion 22 of the retracting tool 20 at the other end of the pipe 10, and the wiring / pipe X is connected to the spare rope 40. Then, as shown in FIG. 13, by pulling back the spare rope 40 to one end of the pipe 10, the wiring / piping material X is drawn into the pipe, and the wiring / piping material X is wired / piped in the pipe. By repeating this work, multiple wiring and piping materials can be
Can be plumbed. The method of using the spare rope 40 is effective for pulling in the wiring / piping material X when it is thick or heavy. It is also effective as a method for drawing wiring and piping materials into pipes buried underground, and for drawing wiring and piping materials into pipes that are bent at multiple locations. Note that the spare rope 40 is connected from the other end of the pipe 10 to one end of the pipe 10.
A method of pulling in with 0 may be used.

FIGS. 14 and 15 are side views showing one example of a wiring and piping method of wiring and piping materials using the hanging cloth fixture 30. FIG. This wiring and piping method is very simple. First, as shown in FIG. 14, the wiring / piping material X is held by the hanging portion 32 of the hanging cloth fixture 30. Next, the hanging pull-in tool 30 is inserted from one end of the pipe 10 while the hooking part 31 is hung on the hooked part 11 of the rail body 12 of the railed pipe 10. Then, as shown in FIG.
By inserting 0 through the other end of the pipe 10, the wiring / pipe X can be suspended / wiped in the pipe. In this method, by providing the rail-mounted tube 10 with the plurality of rail bodies 12 or the hooked portions 31, it is possible to wire and pipe a plurality of wiring and piping materials in the tube. In addition,
In the case where the hanging cloth fixture 30 is inserted into the pipe, the method is not limited to the method of pushing and inserting as shown in FIG. 14, but may be the method of drawing and inserting with the rope 50 as shown in FIG. 16.

As a method of wiring / piping a wiring / piping material into the pipe, a method of wiring / piping a pipe with rails by using both a retracting tool and a hanging cloth mounting tool can be considered. In other words, first, wire and pipe the wiring and piping material into the pipe with the drop-in tool, and then hold the hanging cloth fixture on the rail body used to insert the pull-in tool, and use the wiring and piping with the hanging cloth fixture together. Can be. In the case of a pipe with rails provided with a plurality of rails, one of the pipes is used for wiring / piping material wiring with a retractor.
The other method can be used for piping, and the other method is used for wiring and piping of wiring and piping materials using a hanging cloth fixture.

[0019]

As described above, by using the pipe with rails and the wiring and piping apparatus according to the present invention, the wiring and pipes of cables and fluid pipes already wired or piped in the pipes can be obtained.
There is an excellent effect that wiring and piping work can be performed efficiently without being hindered by piping materials.
