Description

  The present invention relates to a universal band for supporting an overhead electric wire such as a communication line or a power line on a utility pole.

  In general, as shown in FIG. 5, in order to connect the overhead wire 9 such as a communication line or a power line to the utility pole 3, first, a universal band 20 for supporting the overhead wire 9 is attached to the utility pole 3. The universal band 20 is adjusted by adjusting bolts 21 so that the arc shape of the band material 22 is along the circumference of the utility pole 3, and a pair of band materials 22 are arranged on the outer circumference of the utility pole 3, and each tightening nut 7 is fixed. The electric pole 3 is attached by tightening. Next, the end portions of the support wires 10 a and 10 b are respectively gripped by the winding grip 11, and the annular portions 11 a of the winding grip 11 are respectively attached to the connection portions 8 of the universal band 20. Finally, the overhead electric wire 9 is gripped by the cable hanger 12, and the cable hanger 12 is attached to the support wires 10 a and 10 b, so that the overhead electric wire 9 is installed on the utility pole 3.

  By the way, the overhead electric wire 9 may be wired through the utility pole 3 so that the direction changes by 90 °. In this case, in the above method, as shown in FIG. 6, first, the two free bands 20a and 20b are mounted in the vertical direction of the utility pole 3, and one free band 20a is 90 ° with respect to the other free band 20b. Make it rotate. Next, as described above, the ends of the support wires 10a and 10b are each gripped by the winding grip 11, and the annular portions 11a of the winding grip 11 are attached to the connecting portions 8 of the universal bands 20a and 20b, respectively. Finally, the overhead wire 9 is gripped by the cable hanger 12, and the cable hanger 12 is attached to the support wires 10a and 10b, so that the overhead wire 9 is installed at a right angle (that is, the direction is changed by 90 °). To do.

  However, when overhead cables are installed at right angles, the power cable, telephone company, cable TV company, etc. have their own communication lines and power lines for each power pole. Because there are many flexible bands attached to the utility pole, there is no space to install the two flexible bands in the vertical direction even if you want to install a new communication line or power line. There was a problem that a possibility occurred.

  Therefore, the present invention has been made in view of the above-described problems, and provides a free band capable of laying overhead wires such as communication lines and power lines at right angles or substantially right angles with a single free band. It is the purpose.

  The universal band of the present invention that solves the above problems is a universal band for supporting an overhead electric wire such as a communication line or a power line on a utility pole, and has four arc-shaped bands having a shape obtained by dividing the circumference into four. The material is arranged in the circumferential direction of the utility pole, and the adjacent band materials are connected to each other (first invention).

  In the universal band according to the present invention, four arc-shaped band members having a shape obtained by dividing the circumference into four parts are arranged so as to surround the electric pole in the circumferential direction of the electric pole, and adjacent band members are connected to each other. In order to be configured, the connecting portions are arranged in four orthogonal directions. It is possible to connect overhead wires at right angles by connecting a support wire to the two connection portions forming a right angle among these connection portions via a winding grip and attaching the overhead wire to this support wire. Become.

  And since overhead wires can be wired at right angles with one universal band, space is saved compared to the case where two conventional flexible bands are used, and even for utility poles with many overhead wires installed. A free band can be attached and wired. In addition, there is only one free band attached to the power pole, which is superior to the case where two conventional free bands are attached, and the number of tightening of the screw part is reduced, so work at a high place is possible. It can be applied safely in a short time.

  The second invention is characterized in that, in the first invention, an angle formed by the connecting portion where the adjacent band members are connected to each other and the connecting portion adjacent thereto is approximately 90 °.

  A third invention is characterized in that, in the first or second invention, the adjacent band members are connected by screwing means such as bolts.

  In the universal band according to the present invention, the adjacent band members are connected to each other by screwing means such as bolts and nuts, so that the angle formed by the connecting part and the adjacent connecting part is a right angle. By adjusting the tightening degree of the bolt, an acute angle or an obtuse angle can be obtained. Therefore, the overhead electric wire can be wired at an acute angle or an obtuse angle of about 90 °.

  According to a fourth invention, in any one of the first to third inventions, an angle formed by the connection portion and the adjacent connection portion is an acute angle or an obtuse angle by adjusting a tightening degree of the screwing means. It is characterized by becoming.

  By using the universal band according to the present invention, an overhead electric wire such as a communication line or a power line can be wired at a right angle or a substantially right angle with one free band.
