On the other hand, a plurality of arm members 5 are juxtaposed in the laying direction to form a laying path for the cable C, which is a wiring / piping material, and an upper tier arm member 6 forming an upper laying path and a lower laying path. It is composed of a lower arm member 7. The arm member 5 is made of a metal material such as an aluminum material or a steel material, or a synthetic resin material, and is integrally molded to have a constant sectional shape shown in FIG. 5 by aluminum die casting, extrusion molding or the like. The upper half of the arm member 5 can accommodate the retracting force reducing roller 20 from the side, if necessary. Side plates 10 for preventing the cable C from falling are attached to both ends of the arm member 5.

The upper arm member 6 is fitted with an upper detent member 8 at the center thereof, and a screw 19 is inserted from above to form the groove 2
It is attached to the upper wall 3 of the main girder member 2 by being screwed into a. The upper detent member 8 has a body portion 8a having a U-shaped cross section that can be fitted into the upper arm member 6 from above, and plate-shaped standing portions 8b protruding upward at both ends thereof.
Is provided integrally with a protrusion 8c that protrudes downward on the other side and comes into contact with the side end surface of the upper wall 3 of the main girder member 2. Further, the screw 1 is provided at the center of the main body portion 8a.
An insertion hole 8d for inserting 9 is formed. Further, the lower arm member 7 is attached to the lower wall 4 of the main girder member 2 by fitting a lower detent member 9 in the center thereof, inserting a screw 19 from below, and screwing it into the groove 2a. ing.
The lower rotation stop member 9 has a main body portion 9a shaped like a quadrangular plate, and plate-like protrusions 9b projecting upward at intervals that allow the lower arm member 7 to be fitted into the lower arm member 7 from below at substantially four corners. And a hook portion 9c that engages with the side end portion of the lower wall 4 of the main girder member 2 is integrally provided at the upper end of the projecting piece 9b, and further at the center of the main body portion 9a. An insertion hole 9d is formed in which the screw 19 is inserted. The side end surfaces of the upper wall 3 and the lower wall 4 correspond to the side wall of claim 5.

As shown in FIG. 1 , the main girder member 2 is hung in a horizontal direction via hanging metal fittings 12 from hanging bolts 11 hung vertically from the ceiling at predetermined intervals in the longitudinal direction.

Next, the operation of the wiring / piping material receiver and the cable laying on the wiring / piping material receiver of the present embodiment constructed as described above will be described. Although not shown, the cable C is laid in the receiving tool 1 by directly pulling in the cable C using a well-known call rope or the like, or by pulling in the pull-in rope first through the call rope or the like, This can be done by connecting the cable C to the rope and pulling in the pull-in rope. In FIG. 1, the cables C can be laid at a total of four places, two places on the left and right sides on the upper stage and two places on the left and right sides on the lower stage. Thereby, a large number of cables C can be laid even in a place where the width space is small. If the retracting force reducing roller 20 shown in FIG. 5 is housed in the arm member 5, the cable C can be retracted with a small retracting force.

Here, as shown in FIG. 2, the upper detent member 8 and the lower detent member 9 each have projections 8c at four locations.
Since the projecting piece 9b and the projecting piece 9b are in contact with the side end surfaces of the upper wall 3 and the lower wall 4 of the main girder member 2, the arm member 5 moves in the horizontal direction about the central screw 19 mounting portion. Therefore, the arm member 5 can be stably held in the direction perpendicular to the main girder member 2. As a result, the laying path can always be maintained at the maximum width.

Further, since the arm member 5 is provided with the side plates 10 which are erected upward at both ends, the cable C is prevented from dropping from the installation path at the time of retracting or after installation.

Further, the upper detent member 8 has standing portions 8 on both sides.
Since b is erected, it is possible to prevent the cable C from moving more than a certain amount in the width direction of the laying path when or after the cable C is retracted. As a result, it is possible to prevent the cable C from being scratched by being rubbed against the suspension bolt 11 during or after the retracting. In addition, it is drawn into either the left or right laying path,
Alternatively, it is possible to prevent the pulled-in cable C from moving toward the upper wall 3 side of the main girder member 2, getting over it, moving to the other laying path, and entanglement of the cables C with each other. As a result, a large number of cables C can be lined up and installed without meandering.

Although the arm member 5 is attached to the main girder member 2 at the central portion thereof, it can be slid in the width direction so that the left and right protruding lengths are different. Therefore, the receiving tool 1 can be formed according to the situation of the installation place.
However, since the left and right weight balances may be lost and unreasonable stress may be applied to the main girder member 2 and the like, it is preferable to mount the girder member at the central portion.

As described above, in the wiring / piping material receiver of this embodiment, the arm member 5 has the main girder at the appropriate position in the longitudinal direction of the main girder member 2 arranged along the laying path of the cable C. A screw 1 for attaching the arm member 5 to the main girder member 2 so as to be attachable so as to extend laterally from the member 2.
The groove 2a into which 9 is forcibly screwed is formed continuously in the longitudinal direction.

Therefore, unlike the conventional case, the pressing piece 24 is arranged so as to be in contact with the back surfaces of both side edge portions in the main girder member 22, and the fastening bolt 25 is tightened without the troublesome work. After arranging the arm member 5 at an appropriate position in the longitudinal direction of the main girder member 2, a screw 19 is passed through the arm member 5, and further, a simple operation of forcibly screwing into the groove 2a of the main girder member 2 is performed. Thus, the arm member 5 can be attached to the main girder member 2.

Further, since only the groove 2a is formed in the upper wall 3 of the main girder member 2 and the upper opening is small, the strength of the main girder member 2 is large. Therefore, the receiving tool 1 becomes light in weight, easy to carry,
Workability is improved. Further, the main girder member 2 includes an upper wall 3 and a lower wall.
4 and the connecting portions 2b, 2b are formed in a rectangular frame shape.
Therefore, the rigidity of the main girder member 2 itself is strong.

By the way, in the above embodiment, the arm members 5 are provided on both the left and right sides of the main girder member 2, but the present invention is not limited to this, and as described above. Even if there is only one stage, it can be similarly applied. Alternatively, as shown in FIG. 6 , a cantilever structure in which a laying path is formed on only one of the right and left sides of the main girder member 2 may be used. In this case, especially in places with limited width space,
Alternatively, it can be applied to a place where the cable C can be laid from only one side.

Further, in each of the above-mentioned embodiments, the receiving member 1 is composed of the upper wall arm member 6 and the lower arm member 7 in two upper and lower stages, but the present invention is not limited to this and a plurality of stages of three or more stages. It can also be configured to. For example, FIG. 7 shows a three-stage structure of upper, middle, and lower. In FIG. 7 , a middle arm member 17 is attached at a substantially intermediate position between the upper wall arm member 6 and the lower arm member 7,
After the middle stage arm member 17 is fitted with the middle stage attachment member 18 from below the middle stage arm member 17, the screw 19 is inserted from the horizontal direction and screwed into the groove 2a provided in the substantially middle stage of the main girder member 2. By doing so, the main girder member 2 can be extended in the horizontal direction. In this case, it can be applied especially to the installation in a place where the width space is small.

Further, in each of the above-mentioned embodiments, the standing portions 8b of the upper detent member 8 are provided on both sides of the upper wall 3, but the present invention is not limited to this. If it can be prevented from interfering with the suspension bolts 11 and the cables C can be prevented from being entangled with each other, for example, only one can be provided at the center of the main girder member 2.

In addition, in each of the above embodiments, the upper detent member 8 and the lower detent member 9 are externally fitted to the upper arm member 6 and the lower arm member 7, respectively, but the present invention is not limited to this. Instead, it may be provided as an integral part of the upper arm member 6 and the lower arm member 7 as a rotation stopping portion, and in this case, it corresponds to the aspect of claim 2.

Further, although the standing portion 8b of each of the above-described embodiments is provided on the upper stage rotation preventing member 8, it may be directly provided on the upper stage arm member 6 instead of the upper stage rotation preventing member 8. it can. This case corresponds to the aspect of claim 6.
