Problems solved by technology

[0005] However, the connectors used in the above-mentioned construction method combine male terminals and female terminals, and two types of connectors must be prepared in advance. Therefore, the production cost is high. At the same time, the spiral support tool has directionality, so the construction work needs to be done. Spend time

Embodiment Construction

[0084] Embodiments of the present invention will be described below with reference to the drawings. figure 1 ~FIG. 5 are explanatory diagrams which show an example of the process related to the cable hanger construction method using the spiral support tool of this invention.

[0085] First, if figure 1 As shown, the suspension cables 7 are drawn in advance between the utility poles 6a, 6b. Then, from one utility pole 6 a side, the helical support tool 1 is wound around the suspension cable 7 , and the tip of the helical support tool 1 and the suspension cable 7 are temporarily fixed by the fixing metal device 8 . At this time, the fixed metal device 8 allows the catenary wire 7 to slowly and freely pass through the fixed metal device 8 to such a degree that it can move on the catenary wire 7 , and is held by the fixed metal device 8 .

[0086] Below, such as figure 2 As shown, using a special fixture 9, install ropes 10a, 10b on both sides of the fixed metal device 8, so...

Abstract

The invention provides a metal fixing device for a spiral support tool, which can reduce the number of parts to reduce the manufacturing cost, and at the same time, can perform on-site operations in a short time. The fixing metal device (10) of the spiral support tool is composed of a first clamping piece (23), a second clamping piece (24) and a set of bolts (36) and nuts (37), wherein the first 1. The middle part of the clamping piece is provided with a groove for inserting the helical supporting tool, the lower part is provided with a bolt insertion hole (29), and the upper part is provided with a matching part through which the matching part of the second clamping piece (24) is inserted. Holes; the second clamping piece (24) is provided with a slot for inserting the suspension cable in the middle part, has a slot (32) for bolt fitting in the lower part, and has a groove (32) for passing through the first clamping piece in the upper part. The fitting part of the hole is inserted into the fitting part of the hole.

Description

technical field [0001] The present invention relates to a construction method for suspending electric wires, cables or communication wires, etc. on suspension cables drawn between utility poles by using a spiral support tool, and a fixing metal device used in the method. Background technique [0002] Conventionally, a construction method for suspending a cable on a suspension cable drawn between utility poles using a spiral support tool is known, and the methods described in the following gazettes are known. [0003] [Patent Document 1] Patent No. 3203556 [0004] Implementation of this construction method includes the following steps: installing a spiral support tool on a suspension cable near one utility pole and moving it to the other utility pole side; The connector repeats the process of connecting the other end of the helical support and one end of the helical support connected to it; when the frontmost helical support reaches another pole, use a clamp to fix the heli...
