Description

[Detailed Description of the Invention] (A) Field of Industrial Application The present invention relates to a cable support insulator fitting that supports a power cable on a structure.

(B) Prior Art As shown in FIGS. 3 and 4, a conventional cable support insulator has bolt engagement grooves 2 on both sides and a cable holding groove 3 at the bottom thereof, or an insulator 15 having a cable holding groove 3 at the bottom. Insulators 16 placed at the top and bottom of the insulators 15 and 16 were used, but since these insulators 15 and 16 are not provided with a nut relief part, for example, when the insulators are stacked and used as shown in FIG. If two insulators are attached to a connecting bolt with a nut, the nut creates a gap between the upper and lower insulators, making it impossible to grip the cable.

Therefore, when supporting cables on a structure using conventional insulators, there is not much of a problem when supporting the cables on a flat surface of the structure, but when supporting the cables on the ceiling, the side walls of the structure are It is necessary to assemble the insulator, cable, and presser foot between the connecting bolts and sew them all at once.

During this assembly, the insulators and the like move or fall, making the installation work difficult as it requires manpower to hold them.

That is, in the case of single-layer cable support, the cable 9 is sandwiched between the cable holding grooves 3 of two insulators 15 shown in FIG. Since each member is not supported by the bracket until it is fixed to the bracket, the fixing work is not easy because it may move or fall.

Especially when supporting cables in two or three layers,
First, place the insulator 15 shown in FIG. 3 on the bracket with its cable holding groove 3 facing upward, place the cable on this, place the insulator 16, and then
Place the second layer of cable on 6 and insulator 15 on top of it.
Place it face down and use a presser foot to sew it to the bracket at once with a connecting bolt to support it, and in the case of three layers, additional insulators 16 must be used to sew and support it.

For this reason, it is troublesome to use two types of insulators 15 and 16, and the entire weight of the insulators and cables stacked in multiple tiers must be supported by hand until the sewing is completed. Or,
When attaching a bracket that has been preassembled on a bracket to a ceiling or side wall, the weight increases, making the work extremely difficult and requiring a large amount of manpower.

(C) Problems that the invention aims to solve This invention solves the conventional trouble of using two types of insulators as shown in Figures 3 and 4, and the insulators in the bracket when using similar insulators. This was developed to eliminate the difficulty of work, such as having to sew cables all at once.

(D) Means for solving the problem As shown in Fig. 1, horizontal protrusions 1 with vertical bolt engagement grooves 2 in the center are provided protruding from the center on both sides, and vertically extending in the lower center. A rectangular insulator 14 having a right-angled cable holding groove 3 is attached to a bracket 4 having structure mounting bolt holes 6 arranged vertically outside a plurality of connecting bolt holes 5. The bolt engagement grooves 2 are engaged with the coupling bolts 10 so as to face each other, and one or more sets of insulators 14 are screwed together to secure the required number of rows or stages, and from above, the bolts are coupled on both sides. This cable supporting insulator metal fitting is characterized in that it has a structure in which a presser foot 8 having a bolt hole 7 is successively screwed onto a connecting bolt 10 to successively fix the cable to a bracket 4.

In addition, when the presser foot 8 is used to install a plurality of cables 9 side by side, the plurality of presser foots 8 are screwed one after another to the connecting bolt 10 as shown in FIG. Fixed to.

(E) Action As shown in Fig. 2, the bracket 4, which has the required number of coupling bolts 10 fixed to the coupling bolt holes 5 of the bracket 4 with nuts 11, is screwed to the mounting bolt of the structure through the structure mounting bolt hole 6. , the insulator 14 of the present invention is placed with the cable holding groove 3 facing upward,
Between each coupling bolt 10, the bolt engagement groove 2 is placed between each coupling bolt 10,
It is engaged with the connecting bolt 10, inserted, and fixed with the nut 12.

In this case, a required number of insulators 14 are fixed to the bracket 4 in advance according to the number of cables 9 to be supported.

Next, attach the cable 9 to each cable retaining groove 3.
Place the insulator 14 face down on it, and then attach the presser foot 8 to the connecting bolt hole 7 of the insulator 10.
Insert it into the hole, attach it, and tighten it with the nut 13 to support it. In this case, once the insulator 14 placed face down is once hooked to the connecting bolt 10 with a nut, the presser foot 8 is screwed onto the connecting bolt 10, which makes the work very easy when supporting a side wall or ceiling. be.

In this way, adjacent cables 9 are supported on the bracket 4 one after another.

Next, when supporting multiple layers of cables 9,
After fixing the insulator 14 placed face down on the cable 9 to the bracket 4 with the nut 13, place the insulator 14 on top of it.
After fixing the second insulator 14 to the bracket 4 with a mounting nut with the cable holding groove 3 facing upward, the second layer cable 9, insulator 14, and presser foot 8 are fixed to the coupling bolt 10 with nuts.

In the case of three layers, similarly, the insulator 14 may be used to fix the structure.

(F) Effect of the invention In the cable support insulator metal fitting of the invention, not only can the cables 9 arranged horizontally be fixed one after another to the bracket 4 using one type of insulator 14 as described above, but also the two-layer insulator For fixing the three layers, one type of insulator 14 can be used by stacking them on the front and back, so there is no need to use two types of insulators.

In addition, since nut reliefs are provided at the top and bottom of the protrusion 1, the conventional insulators 15 and 1 shown in FIGS.
Like in case 6, Natsuto does not get in the way of stacking the insulators.

Since each insulator 14 can be fixed to the bracket 4 as necessary, when supporting the cable 9 on the side wall or ceiling of a structure, the cable 9 can be supported individually.

Therefore, the work is easy and does not require a lot of manpower, etc.
It has many excellent effects.

(G) Other Examples The present invention can be used not only to support cables inside building ducts, but also to support cables inside underground cable ducts, etc., and can be used for cable support work in narrow work spaces. It has the convenience of allowing a small number of people to work together.
