Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a holder for a vertically laid cable that is laid in a vertical direction indoors, such as in a high-rise building, and is improved so as to be convenient for handling and the like.
[0002]
[Prior art]
As shown in FIG. 4, a conventionally known vertical laying cable holder has a pair of left and right halves that are pivotally attached to one end and pivotable to each other, and can be tightened to each other. It consists of cylindrical holders 1 and 2, and one of the holders 1 is vertically attached in the longitudinal direction, and an inner plate 4 a is fixed to the outer peripheral surface of the holder 1. A holding frame 4 having a cross-sectional shape (not shown, but functioning as a mounting portion to a support fixed to the cable laying side) 4 is projected, and an outer plate portion 4b of the holding frame 4 has a fastening bolt 5 Are joined to each other, and the joint portions 1a and 2a provided at the other end portions of both the holding bodies 1 and 2 are connected to the joint portions 1a and 2a in such a manner that they can be inserted and removed. The nuts 7 and 7 are configured to be coupled by tightening operation.
[0003]
[Problems to be solved by the invention]
In this conventional holder, the inner plate portion 4a of the holding frame 4 is vertically attached over the entire length in the length direction of the holding body 1, so that it is expensive to provide the holding frame 4, and the U bolt 6 Is relatively expensive and increases the cost. In the structure in which the holding bodies 1 and 2 are tightened by using the U-bolt 6, the holding bodies 1 and 2 cannot be largely deployed unless the two nuts 7 and 7 are removed. In some cases, it is very inconvenient, and the work is often performed at a high place, and the removed nut is often dropped and lost, and there is also a problem that the progress of the work is hindered.
[0004]
The present invention solves such a problem, and an object of the present invention is to reduce the material cost by making the holding frame as small as possible, and at the same time, a structure that does not use a relatively expensive U-bolt. Thus, an object of the present invention is to provide a vertical laying cable holder improved so as to achieve a significant cost reduction. Another object is that the holding body can be greatly expanded while the nut is screwed to the coupling bolt, and at the same time, the coupling bolt is removed from one holding body while the nut is screwed. An object of the present invention is to provide an improved vertical laying cable holder that can completely eliminate the problem of losing bolts and nuts and is extremely convenient for handling.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, a vertical laying cable holder characterized by the present invention is a vertical laying cable that holds a cable and is attached to a support arm portion of the support so that the held cable is in a vertical direction. In this holder, one end portion is pivotally attached to each other, and the other end portion is composed of a pair of left and right semi-cylindrical holders, and a cable can be held between both holders, A holding frame is provided on the outer peripheral surface portion of one of the two holding bodies, and the holding frame is apparently tunnel-shaped with respect to the outer peripheral surface portion along the axial direction of the holding body. The upper portion when the cable is laid vertically is formed in the gate-shaped portion, and the gate-shaped portion is fixed on the outer peripheral surface portion, and the lower portion when the cable is laid vertically is the outer peripheral surface portion. Away from the top And a bolt for tightening and fixing a support arm portion of the support inserted between the outer peripheral surface portion and the lower portion is screwed to the lower portion thereof, and One of the joints provided on the other end side of both holding bodies has a long hole in which a connecting bolt is removably inserted, and the other joint has the long hole. Corresponding to the insertion bolt, a through hole having a large diameter portion through which the nut screwed can be passed, and the width of the portion other than the large diameter portion in the insertion hole is so large that the nut cannot pass through. This is the configuration.
[0006]
In this configuration, when the support arm portion of the support fixed to the cable laying portion side is tightened on the outer peripheral surface portion with the tightening bolt, the outer peripheral surface portion of the holding body to which the holding frame is fixed is It is preferable to provide a pair of protrusions so as to be opposed to each other in the screwing direction of the tightening bolt so that the supporting arm portion and the outer peripheral surface portion can come into contact at two points, in order to firmly stabilize the supporting state of the holder. .
[0007]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 and 2. A vertical laying cable holder that is attached to a support arm portion of a support described later so that the held cable is in the vertical direction. A pair of left and right holding bodies formed in a semi-cylindrical shape that can be joined at the other end, and the cable can be held between the holding bodies 11 and 12. A holding frame 14 is provided on the outer peripheral surface portion 11 a of one holding body 11, and this holding frame 14 is apparently tunnel-shaped with respect to the outer peripheral surface portion 11 a along the axial direction of the holding body 11. A portion that becomes the upper side when the cable is laid vertically is formed in the gate-shaped portion 14a and is fixed on the outer peripheral surface portion 11a by the gate-shaped portion 14a, and a portion that becomes the lower side when the cable is laid vertically is the outer periphery. It is separated from the surface portion 11a.
[0008]
A nut 15 is fixed inside the portion of the holding frame 14 which is the lower side, and a tightening bolt 16 is screwed to the nut 15. 17 is a fool hole through which the fastening bolt 16 is passed. And the long hole 18 exists in the junction part 11b by the side of the holding body 11 among the flat-plate-like joining parts 11b and 12b by the side of the said other end of both the holding bodies 11 and 12, and the said joint part 12b by the side of the holding body 12 is the said. An insertion hole 19 is provided corresponding to each of the long holes 18. A coupling bolt 22 that is screwed into the nut 21 is removably inserted into the long hole 18, while one end of the insertion hole 19 is formed as a large diameter portion 19 a through which the nut 21 can pass. The width of the portion of the insertion hole 19 other than the large portion 19a is such that the nut 21 cannot pass through.
[0009]
A pair of protrusions 23 and 23 are provided on the outer peripheral surface portion 11 a of the holding body 11 from which the holding frame 14 is protruded so as to face the screwing direction of the tightening bolt 16.
