Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cable construction method for tensioning a cable to a metsenger wire.

For example, as a conventional construction method for constructing a coaxial cable for CATV, the method shown in FIG. 1 has generally been used.

1 is a cable, 2 is a metsenger wire, and these are connected to the lashing rod 3 at a predetermined interval t (for example, 750 mm).
The ice wire is made by twisting the wires at a distance of 1 mm). Furthermore, the spaced portions of the lashing rods 6 are fixed at one or two locations with binding wires 4, as required.

In this case, the lashing rods 6 must be taken out one by one, which poses the following problem.

(1) It is not easy to arrange the lashing rods at equal intervals, and the finish becomes uneven.

(2) It is inefficient to take out the lashing rods one by one, and there is also an unsafe element of the lashing rods falling to the ground.

The present invention solves the above-mentioned problems, and aims to provide an erection method that can improve work efficiency and provide a good finish.

Hereinafter, one actual flow side of the present invention will be explained.

FIG. 2 shows a continuous member 5 used in the present invention, in which lashing rods 6 are arranged at approximately equal intervals via connecting lines 7 having a length t.

The continuous member 5 is installed together with the Messenger wire when the Messenger wire is connected, and the Messenger wire and the cable are integrated by wrapping around the lashing rod 6 after the cable is subsequently extended.

FIG. 6 shows an example in which the cable 1 and the messenger wire 2 are integrated by a continuous member 5, and each song slot 6 is twisted in opposite directions around the connecting line 7.

It is preferable to use the continuous member 5 with a length equal to the distance between utility poles, but the continuous member 5 may be longer or shorter than this.

The connecting line 7 may be left as is, or it may be cut and used as a binding line.

According to the present invention explained above, the following effects can be obtained.

(1) It is no longer necessary to feed the lashing rods from below and tie them one by one, and the work efficiency is greatly improved because the time and effort of measuring the intervals can be saved.

(2) The lashing rods can be arranged at equal intervals, resulting in a good finish.

(6) Since the lashing rod and cable exist in parallel, the tying work is very efficient and there is no need to worry about the lashing rod falling.
