Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a temporary cable holder, and more particularly to a device suitable for temporarily temporarily placing the cable into a figure 8 shape when the cable length is long.

[Conventional technology]

Conventionally, when laying a cable in an underground buried pipeline, laying a trough-accommodating cable, or an aerial cable, if the laying length is long, the tension on the cable and the load on the indexer will increase, so There is known a method of first laying from the first half to the first half and temporarily laying it in a figure 8 shape until it is laid in the second half (JP-A-62-36444). If the method of temporarily placing in a figure 8 shape is adopted, it is possible to cancel the twist generated in the cable, which is very preferable.

However, even if the cable is temporarily placed in the shape of a figure 8, it cannot be placed randomly, so normally the figure is drawn and the position is gradually shifted so that the figure 8 does not collapse and The cable is installed so that it can be easily pulled out.

[Problems to be solved by the device]

However, in the above-mentioned conventional temporary placement method, since it is not possible to vertically stack while drawing the figure 8, there is a problem that a large space is required for a flat installation and such a temporary placement cannot be performed in a narrow construction site. In addition to the problem that the temporary placement form is not constantly maintained, there is also a problem that the lower cable jacket is deformed and damaged at the intersection of the figure 8 due to the cable weight.

Focusing on the above-mentioned conventional problems, the present invention is capable of surely stacking a figure 8 in a certain size while stacking it upward, and temporarily placing it so that the weight of the cable at the intersection does not add to the lower cable. The purpose is to provide a temporary cable holder that can be used.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, a cable temporary placing tool according to the present invention is an instrument for temporarily placing a cable in a figure-eight state, and a flat surface V is provided on a pair of columns that are erected so as to sandwich a cable intersection. The support arms of a character shape are provided so as to be opposed to each other, and the support arms are mounted with a step between the pair carrying one of the intersecting cables and the pair carrying the other cable, and the intersection guide formed by forming these in multiple stages The circular arc guide is composed of a plate erected along the outer surface of the circular arc portion.

[Action]

According to the above configuration, when the cable is introduced at the intersection of the figure-8, the cable is first hung on the one side support arm of the opposing strut, turned along the inner peripheral surface of the arc guide on the one side, and the intersection guide is again provided. To introduce. Since the intersecting portion guides are orthogonal to each other this time, it is sufficient to draw the figure 8 as a whole along the inner peripheral surface of the opposite circular arc guide after being hung on the corresponding support arm. If this is continuously performed, the cross guides are surely stacked by the multi-stage support arms, and the arc guides are not separated from the guide surface due to the bending resistance of the cable, so that the guides can be stacked again. This allows the cables to be stacked in the shape of a figure 8 on the top,
In particular, it is possible to temporarily place the lower cable at the cable intersection without applying the load of the upper cable.

〔Example〕

Hereinafter, an embodiment of a temporary cable holder according to the present invention will be described in detail with reference to the drawings.

FIG. 1 is a plan configuration diagram of a temporary cable holder according to the embodiment, in which cables 10 to be temporarily placed are stacked so as to draw a figure 8 composed of an intersecting portion 10A and arc portions 10B on both sides. In order to guide such a cable 10, an intersection guide 12 is installed at the intersection 10A, and an arc guide 14 is provided in the arc portion 10B to regulate the diameter of the arc guide 14 so as not to expand. These make up the cable temporary storage device.

First, the intersection guide 12 is located at the cable intersection 10A, and as shown in FIGS. 2 to 4, two columns 16 facing each other are erected on a column pedestal 18. The column 16 has a protrusion 20 integrally projecting from the lower end of the cylinder, and is attached by fitting this to a fixed cylinder 22 provided on the column support 18. Support arms 24 are planted in multiple stages at regular intervals on each of the opposing wall surfaces of the pillar 16, and the support arms 24 at the same height are formed from two bar members opened in a V shape. . Support arm 2 for each column 16
4 are arranged so that the V-shaped opening side faces toward the other side, so that, as shown in FIG. 1, the support arms 24 in parallel relationship between both columns 16 are in the laying direction of the cable 10 and are in the same plane. The cable 10 is supported by. The support arm 24 is attached so that the tip end thereof is slightly higher than the base end end so that the cable 10 is not easily detached.

Next, as shown in FIGS. 5 to 6, the arc guide 14 has a flat cross-shaped installation metal fitting 26, and each leg of the installation metal fitting 26 has a telescopic structure so that it can be expanded and contracted. Has become. At the tips of the legs in the three directions, a receiving strut 28 having a height substantially similar to that of the strut 16 of the cross guide 12 is erected, and an arc plate 30 is attached to the inner surface side thereof. ing. Therefore, in the plan view with the legs of the installation fitting 26 extended, the cable 1
The circular arc portion 10B of 0 is placed on the locus of a circle that regulates the outer diameter. The extension direction of the leg at one place without the arc plate 30 is at the cable intersection 10A, and it may be connected to the support pedestal 18 of the intersection guide 12 if necessary.

The temporary cable holder configured in this way is used for the cable 1
0 is introduced along the locus of the figure 8, and is placed on the support arm 24 in one direction of the intersection guide 12. Then, it is curved so as to draw an arc following the arc plate 30 of the arc guide 14, reaches the intersection guide 12 again, and intersects in the orthogonal direction this time, and is placed on the support arm 24 one step higher. It is introduced into the circular arc guide 14. When the cable 10 is laid so as to draw a figure 8 in this way, in the central intersection guide 12, the multi-stage support arms 24 prevent stacking deviations and each support arm 24 supports the cable 10, so that The load on the cable is prevented. Further, in the circular arc portion 10B, the circular arc plate 30 of the circular arc guide 14 prevents the diameter from expanding, and the cables 10 are stacked, so that the cables 10 can be laid temporarily in a figure 8 shape while maintaining a predetermined shape. In this case, in the arc portion 10B, the arms similar to the support arm 24 are projected at every several stages so that, for example, the cables stacked in five stages are collectively supported. It is possible to prevent deformation and damage due to.

In addition, in the above-mentioned embodiment, the pillar 16 has a protrusion 20 at the bottom.
The support 16 is provided so as to be fitted to the fixed cylinder 22 of the pedestal 18 so as to stand upright. However, the columns 16 can be inserted and connected to each other, and the height of the column 16 can be changed according to the stacking height of the cables. You can do it. This is protrusion 2
It can be realized by inserting 0 into the upper end opening of the pillar 16 that is standing first.

[Effect of device]

As described above, the cable temporary storage device according to the present invention is a device for temporarily storing a cable in the shape of a figure 8.
Planar V-shaped support arms are provided so as to face each other on a pair of stanchions that are erected so as to sandwich the crossing portions of the cables, and the support arms have a step between the pair on which one of the intersecting cables is placed and the pair on which the other cable is placed. Since it is composed of cross guides that are attached and formed in multiple stages and arc guides that are plates that are erected along the outer surface of the arc portion of the cable, lay them so as to draw the figure 8 accurately. Since it can be stacked up only in the first 8-shaped space and can be temporarily placed so that its own weight will not be applied to the lower cables, it is possible to work even in a narrow field and there is no cable deformation or damage. The effect that the cable can be temporarily placed without fear can be obtained.
