【The invention's effect】
The present invention has the following effects by the configuration and operation as described above.
1. Since the fixed angle can be attached to the wall surface or the erection body can be attached to the wall surface using suspension bolts, for example, when installing a cable in a railway tunnel, the workability is good and the cable is efficient. Can be installed.
2. Since the cable holder can be mounted in any direction by using a fixed angle or using anchor bolts, the main body of the installation device can be used in general according to the situation at the site. .
3. When mounting the main body to the fixed angle, it is necessary to use only two bolts, which is normally required by using a projection and bolts. Not only can the parts cost be reduced.
4). Since the nut for each bolt is placed in the fitting port so as to prevent the rotation, it is not necessary to perform the tightening work by preventing the rotation while holding the nut or the bolt at the site. good.
5). Since the cable or the like can be fixed to the cable holding portion using a cable fixing band, the cable or the like is stabilized. At this time, by using the protector, there is no worry of damaging the cable or the like.
6). Since the cable holding band has a plurality of cable fixing band through holes, the cable holding portion can be fastened and fixed corresponding to the diameter of the cable or the like.
7). As for the cable erection device, the construction cost of cables and the like can be reduced by the simple structure and the smaller number of parts.
8). Forming the main body of the installation device, the cable fixing band, and the protector with a resin that does not use a halogen element reduces the amount of toxic gas and black smoke generated especially in the event of a fire in the tunnel, which is an effective safety measure.
