BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a utility pole band used for tensioning a branch line or for mounting various types of equipment.

[0002]

2. Description of the Related Art As a conventional example, Japanese Utility Model Publication No. 55-43281
As described in the publication of the publication, through holes are provided at equal intervals over a range of a required length on at least the other end side of a band body having one fastening member fixed to one end, and the band piece is provided at the other end side. The other side of the board that can swing freely is mounted on the other side of the board, and the other clamp is attached to the rising piece, and the locking piece provided on the lower edge of the tightening piece is passed through to the desired position. There is a structure in which the band piece is wound around an electric pole after being inserted into and locked in, and a tightening bolt is inserted into both of the opposite tightening receiving pieces facing each other, and a tightening nut is screwed and tightened at the tip thereof.

[0003]

[Problems to be Solved by the Invention] In the case of the conventional example,
When attaching to the utility pole, hold the clamps provided on both ends of the band wound around the pole with both hands and hold them tightly while holding them in close proximity, and from one clamp to the other. After passing the tightening bolts through the metal fittings and screwing the nuts onto the ends several times to temporarily fix the band to the utility pole, take out the tightening tool such as a spanner and fully tighten these tightening bolts and nuts. However, in actual work, it requires a great deal of manpower and labor to screw the nuts, especially while gripping both tightening fittings with both hands. Since I released my hand without noticing that the screwing was incomplete, the elasticity of the band piece caused the nut to come off, causing the band itself to drop.
Alternatively, the tightening metal may fall off the band piece 1 due to a momentum during work, which not only causes a great delay in work time, but is also not preferable from the viewpoint of safety.

In view of such circumstances, the present invention provides a band for utility poles in which the band body can be easily mounted without removing the tightening bolts and nuts on the pillars, and there is no risk of falling nuts or the like. It was devised for the purpose of doing.

[0005]

A first tightening metal fitting is provided on one side of a band piece in which through holes are provided along at least both ends along a longitudinal direction, and a locking portion is provided on the other side of the band piece. Second fastening metal fittings, each of which is fitted and locked into a desired through hole, are provided, and the second fastening metal fitting is provided on the back surface of the band piece so as to be swingable; And a tightening receiving piece pivotally attached to a rising piece that is erected opposite to each other with a tightening bolt penetratingly locked to the first tightening metal fitting, and the tip of the tightening bolt is fixed to the locking portion. In a band for telephone poles that penetrates the tightening receiving piece of the second tightening metal fitting provided with a piece and equips the tightening nut with this, tighten the first tightening of the band piece to the end of the second tightening metal fitting side of the band piece. A temporary stop piece that engages with a through hole provided on one side of the metal fitting is erected, and the head of the tightening bolt is formed in a rectangular shape. Passed through constituting provided bolt through holes to open shaped locking in the clamping receiving piece of the first fastening bracket.

[0006]

Operation: A first tightening metal fitting provided on one side of the band piece wound around a telephone pole, and a second tightening metal fitting having a locking portion piece fitted and locked in a desired through hole on the other side of the band piece. At the same time, place both ends of the band piece close to each other by sandwiching them with both hands, and feed the other end of the band piece to the lower side of the first tightening piece, and attach the temporary piece at the end to the band piece. Since the band body is temporarily fixed to the utility pole by being locked in the through hole that is lined up on one side, there is no concern that the band body will drop even if both hands are released from both fastening fittings at this stage.

Accordingly, the bolt receiving hole of the second fastening member is made to penetrate through the bolt passing hole so that the head portion is located in the vicinity of the bolt receiving hole of the first fastening member so as to project from the bolt passing hole. The head of the tightening bolt, which is lightly screwed with a tightening nut, is passed through the bolt through hole provided in the tightening receiving piece of the first tightening metal fitting, and both hands are fully assembled for rotation. The same work can be done easily.
