しくない。Conventional Technology and Problems Conventionally, this type of flexible band for utility poles has been used with diagonal branch lines stretched across the tension bolts extending between the tension receiving edges of two opposing band pieces. When excessive tension is applied during a typhoon, etc., a force is applied that pulls down the tightening bolt, and the band piece rotates downward around the connecting bolt on the other end and slides down, releasing the tension. When a branch line is damaged, it does not return to its original state, so the branch line becomes slack, and since then, branch lines that have no longer been used can be seen here and there in the city, which is not good for safety.

ものである。Means for Solving the Problems The present invention provides an outwardly bulging edge at the other end of the conventional flexible band, that is, a strip having a plurality of connecting holes arranged in a row on one end side. The band piece is improved by forming a tightening receiving edge by bending the middle part on the other end side having the bulging edge, and providing a through hole for a tightening bolt in the bulging edge on the tip side of the tightening receiving edge. This was devised with the aim of eliminating the drawbacks of the conventional method.In order to achieve this purpose, both sides of the bent part of the band-shaped body are made to protrude from each side to make it the widest part, and the band-shaped body is bent at two places. The bulging edge of the bent portion serves as a reinforcing oblique side.

A bulging edge 3 is provided at the other end facing outward, the middle part of the bulging edge 3 is bent to form a tightening receiving edge 5, and a tightening bolt is attached to the bulging edge 3' of this tightening receiving edge 5. 7 through holes 8 are provided, and both sides of the bent portion of the tightening receiving edge 5 are made to protrude in an F-shape, respectively, to form the reinforcing edge 4,
4 to form the widest part, and the swollen edge of the bent part formed by bending at two places to serve as the reinforcing oblique side 6.

止される。Effects of the invention Since the invention has the above-mentioned structure, for example, as shown in Fig. 2, the vertical component of the tension T 1 of the diagonal branch line is
The downward rotation of the band piece A around the connecting bolt 10 due to T1 ' is prevented by a reinforcing edge provided at the bent part of the tightening receiving edge closest to the load point of the band piece A that is in close contact with the utility pole D. 4 acts as a fulcrum and blocks the reinforcing edge 4 of the tightening receiving edge 5 into a vertical bending load, thereby preventing the band piece A from slipping down.
又、該補強縁４部は既述の通り最広幅部を形成
しているので前記曲げ荷重に充分対応する断面係

経済的な観点からも実用価値大なるものがある。 Further, since the reinforcing edge 4 portion forms the widest portion as described above, it can have a section modulus that sufficiently corresponds to the bending load. One branch line 12
When T is a horizontal branch line, the tension T 2 acts on the band piece A as a force that stretches the tightening receiving edge formed by bending it into a straight line. It can effectively prevent straightening of the tightening receiving edge in response to force, has a large resistance to both horizontal and diagonal branch line tension, and is safe as it does not deform. There is no need to increase the amount of material used, such as by increasing the size of the pieces, and it has great practical value from an economical point of view.
