It consists of and.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a flat lashing rod, and more particularly to a flat lashing rod that has good cable securing properties and at the same time is unlikely to bite into the outer circumference of the cable.

[0002]

[Prior art]

 When laying electric wires or communication cables, as shown in Fig. 1, the above-mentioned cable 2 is installed below the horizontally fixed suspension wire 1, and the outside of both the suspension wire 1 and the cable 2 is installed. A lashing rod 3 is spirally wound around the cable 2 to suspend the cable 2 on the suspension wire 1.

Here, as the lashing rod 3, a steel wire having a circular cross section is generally formed into a spiral shape to have a desired spiral diameter.

[0004]

[Problems to be solved by the device]

 By the way, the cables have different diameters according to the purpose of use. Therefore, if a lashing rod with a spiral diameter that is too large for the cable diameter is used, slippage may occur between the lashing rod and the cable or suspension wire, which may cause the cable to move, thus ensuring cable availability. Will fall. Conversely, if a lashing rod whose spiral diameter is smaller than the cable diameter is used, the lashing rod has a circular cross section, so the lashing rod bites into the insulating coating layer that forms the outer circumference of the cable, degrading the cable's insulation characteristics. It may cause a problem.

Therefore, a coating layer made of a soft resin such as polyethylene resin or nylon resin is formed on the outer circumference of the lashing rod to increase the friction resistance with the outer circumference of the cable and also to improve the outer circumference of the cable. It is also practiced to suppress the above-mentioned bite into.

However, even if such a measure is taken, since the cross section of the lashing rod itself is circular, there still remains a problem that biting into the outer circumference of the cable is likely to occur.

An object of the present invention is to solve the above problems in the conventional lashing rod, to provide a cable securing property, and to provide a flat lashing rod which hardly bites into the outer circumference of the cable.

[0008]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention comprises a lashing rod body formed of a flat plate steel wire having a rectangular cross section and an elastic coating layer for coating the surface of the lashing rod body. A flat lashing rod is provided, which is also characterized in that a flat lashing rod with colored caps attached to both ends is provided.

[0009]

[Action]

 Since the flat lashing rod of the present invention has a quadrangular cross section, the contact with the outer circumference of the cable is wide. Therefore, it is possible to prevent the cable from getting into the outer circumference. Further, since the elastic coating layer is formed on the entire outer circumference, the frictional resistance with the outer circumference of the cable is large, and the sliding phenomenon with the cable is suppressed.

[0010]

【Example】

 Hereinafter, the flat lashing rod of the present invention will be described in detail with reference to the drawings. 2 is a perspective view showing a part of the flat lashing rod of the present invention, and FIG. 3 is a sectional view taken along line III-III of FIG.

In the figure, the flat lashing rod 4 of the present invention comprises a lashing rod body 4a made of a flat steel wire having a quadrangular cross section and an elastic coating layer 4b covering the periphery thereof, and the whole is formed in a spiral shape. And has a desired spiral diameter d.

The width and thickness of the lashing rod body 4a in the cross-sectional shape are not particularly limited, but are, for example, 4.5 mm in width and 1.5 mm in thickness.

Further, since the elastic coating layer 4b comes into contact with the soft cable outer periphery, it is preferable that the elastic coating layer 4b is a coating layer made of a soft material that has some elasticity and does not damage the cable outer periphery. A layer of nylon resin or polyethylene resin can be mentioned.

This flat lashing rod 4 is formed by spirally forming a flat steel wire having a predetermined cross-sectional shape into a desired spiral diameter to form a lashing rod body, and then, on the surface of the lashing rod body, The resin as described above can be produced by coating, for example, by a fluid immersion method.

Next, the operation will be described.

When the cable is attached to the suspension wire and the flat lashing rod of the present invention is spirally wound from the outside of both, the contact portion between the suspension wire or the cable outer periphery and the flat lashing rod becomes a surface contact state, and the contact is made. The area becomes large.

Therefore, the flat lashing rod is less likely to bite into the outer circumference of the cable, and biting damage to the outer circumference of the cable is suppressed.

Further, since the friction resistance between the flat lashing rod and the outer circumference of the cable and the suspension wire also becomes large, it becomes difficult to slip, and the cable securing property is improved.

In the flat lashing rod of the present invention, if caps of various colors are attached to both ends according to the size of the spiral diameter d, it can be used properly according to the diameter of the cable to be erected. Become.

[0020]

[Effect of device]

 As is clear from the above description, the flat lashing rod of the present invention comprises a lashing rod body formed of a flat plate steel wire having a rectangular cross section, and an elastic coating layer for coating the surface of the lashing rod body. Since it is made of, it is possible to suppress the bite from entering the outer circumference of the cable and to improve the securing of the cable.
