[02001] [02001] Conventionally, a piping material 20 as shown in FIG. 13, for example, has been used for floor wiring. This piping material 20 is
A main body 21 for wiring cables and the like inside is formed of a metal material into a rectangular cylindrical shape, and a plurality of wiring outlet ports 22 each having female threads 22a are formed at predetermined intervals on the upper surface of the main body 21. A wiring port member called an insert stud 23 is attached to the wiring outlet 22. [03001 When wiring a cable C such as an electric wire or a signal line using such a conventional piping material 20, as shown in FIG. Junction box 12 installed in
After inserting into the main body 21 from the top opening or the top opening of the insert stud 23, pulling it out from the top opening of another junction box 12 or the insert stat 23, and connecting the cable C to the end of this call line 30. By pulling back the call line 30, the cable C was drawn into the main body 21 for wiring. [04001] [Problems to be Solved by the Invention] However, when wiring cables using such conventional piping materials, since the wiring outlet is formed at a predetermined position, it is difficult to take out the cable. The position is restricted, thereby ○A
There were some inconvenient wiring issues, such as restrictions on the installation locations of equipment, etc. in the room, and the need to run separate wiring on the floor. [05001 In addition, the conventional piping material 20 requires a large number of parts to attach wiring port members such as the insert stand 23, and the wiring outlet 22 is formed with a female thread 22a, which makes manufacturing cumbersome and increases costs. There was a problem. [06001 This invention has been made in view of the above circumstances, and its purpose is to provide a floor in which a pull-out hole can be provided at any position of the piping material and the cable pull-out position can be freely set. An object of the present invention is to provide a wiring method and piping materials used therein. [07001 [Means for Solving the Problems] As a means for solving the above-mentioned problems, the invention according to claim 1 provides ``a synthetic resin-made wire having a conductive wire continuous in the length direction at the center of one side. The piping material is buried in the slab with the conductor facing downwards, and the center position of the buried piping material is detected from above the slab surface by detecting the electromagnetic field generated by passing a current through the conductor. A floor wiring method characterized by forming a pull-out hole that penetrates to the piping material using a punching tool with the position at the center, and pulling out the cable routed inside the piping material.
It is. [08001 Still, the invention as claimed in claim 2 is ``a piping material formed of synthetic resin into a cylindrical shape through which a cable is inserted, and having a conductive wire continuous in the length direction at the center of one side. ”. [09001] [Function] According to the floor wiring method according to claim 1 configured as described above, a pull-out hole is provided at an arbitrary position of the piping material and the cable is pulled out according to the installation position of OA equipment etc. in the room. be able to. [10001 Furthermore, the piping material according to claim 2 is suitable for the above-mentioned floor wiring method, and can be easily manufactured because it has a simple structure having a cylindrical shape as a whole. [1100] [Embodiments] Hereinafter, embodiments embodying the invention according to claims 1 and 2 will be described in detail based on the drawings. For convenience of explanation, the piping material according to claim 2 will be explained first. [12001 Fig. 9 shows an embodiment of the piping material 1. The main body 2 of the piping material 1 is formed into a cylindrical shape with a square cross section, and a longitudinal hole is provided in the center of one side of the main body 2. The conductive wires 3 are continuously embedded integrally. [1300] The main body 2 of the piping material 1 is made of synthetic resin so as not to interfere with the detection of the electromagnetic field generated by passing a high frequency current through the conductor 3. In addition, since it is made of synthetic resin, it is possible to easily make a hole in the main body 2 of the piping material 1 using a punching tool. [14001 The conducting wire 3 may be molded integrally with the main body 2 of the piping material 1 and embedded therein, or may be a separate body and attached to the main body 2 later. Further, as the attachment form of the conducting wire 3, terminals may be formed at both ends of the main body 2 as shown in FIG. 10, or both terminals may be formed at one end of the main body 2 as shown in FIG. . The conducting wire 3 is placed outside the main body 2 of the piping material 1 in order to prevent it from being damaged by a punching tool, but even if it is placed inside the main body 10 of the piping material 1 as shown in FIG. good. Further, the conducting wire 3 is arranged at the center of the outer surface of the main body 2 of the piping material 1 so that the detected position is the contact position of a center drill when drilling a hole with a drilling tool such as a hole saw. [The shape of the main body 2 of the 15001 piping material 1 is not particularly limited to a square cross section, and may have other cross-sectional shapes such as a circle, and the outer shape is not limited to a smooth cylindrical shape, but may be flexible. In order to increase the durability, the outer surface may have a corrugated shape with unevenness, and in short, any structure may be used as long as a cable such as an electric wire or a signal line can be inserted inside. [16001] Next, the floor wiring method according to claim 1 will be explained using such piping material 1. [17001 First, as shown in FIG. 1, the main body 2 is adjusted to a predetermined height and installed on the floor 11 via the adjustment port 8 and the support fittings 9. At this time, it is installed with the conducting wire 3 facing downward. Next, as shown in FIG. 2, concrete is placed on the floor surface 11 to form a slab 10, and the piping material 1 is buried therein. [18001 Next, when wiring cables C such as electric wires and signal lines to the piping material 1 embedded in the slab 10,
As shown in FIG. 3, an electric current is passed through the conductor 3 to generate an electromagnetic field, and the generated electromagnetic field is detected by the detector 4 as shown in FIG. Detect from. [19003 Next, as shown in FIG. 5, at the position where the cable C is pulled out, the center drill 5a of the hole saw 5, which is a drilling tool, is aligned with the detection position to make a hole, and as shown in FIG. A pull-out hole 6 is formed over the upper surface of the main body 2, and an opening fitting is fixed to the pull-out hole 6. [20001] Next, as shown in FIG. After connecting the cable C to the end of the main body 2, the call line 30 is pulled back and the cable C is pulled out from the pull-out hole 6 as shown in FIG. 8, thereby drawing the cable C into the main body 2 and wiring it. The pulled out cable C is connected to an outlet etc., and in this state the outlet etc. is attached to the opening fitting 7.
