[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flexible pole for attaching a power pole for hanging electric wires, communication cables and the like on a power pole.

[0002]

2. Description of the Related Art An electric pole is usually wired with a predetermined height of 5 m or more from the ground. However, in order to further extend a communication cable on this pole, a telephone pole for suspending the communication cable is used. A mounting band must be attached to the utility pole. Examples of such a power pole mounting free band include those shown in FIGS. 17 and 18.

In FIG. 1, reference numerals 101 and 102 denote band members. The band members 101 and 102 are composed of a pair of band pieces 103, 104, 105 and 106, respectively.
5 and 106 each have a plurality of adjustment holes 103a, 1
04a, 105a and 106a are drilled.

Each of the plurality of adjusting holes 103a, 103
4a, 105a, and 106a, the adjusting bolts 107 and 108 are inserted into a pair of adjusting holes 103a and 104a and 105a and 106a, respectively, and the nut 1
Temporarily fixed by 09,110. At this time, hanging hardware 111 for hanging a communication cable is attached to the adjusting bolts 107 and 108.

In order to wire a communication cable to a telephone pole, 5
The power pole mounting free band is mounted above the electric wire that has been wired to a predetermined height of at least m. Therefore, the adjusting holes 103a, 1
04a, 105a, 106a, adjusting bolts 107, 10
8. With the pair of band members 101 and 102 whose lengths have been adjusted and temporarily fixed by the nuts 109 and 110, the band members 10 and 102 climb up to a location 5 m high on the utility pole, and
1 and 102 are arranged on the periphery of the utility pole 112 and
3, the nuts 114 are connected by a nut 114. At this time, the temporarily fixed nuts 109 and 110 are tightened.

By the way, since the pole 112 has a tapered shape with a large diameter at the lower end and a small diameter at the upper end, the diameter of the pole 112 is slightly different depending on the mounting position. Therefore, the band member 1 is placed at a desired height of the telephone pole.
Even if an attempt is made to mount a utility pole mounting band whose length has been adjusted in advance, the diameter may not match, and in such a case, it is necessary to correct the band diameter.

For this purpose, the band pieces 103, 104,
105, 106 formed in adjustment holes 103a. 104
a, 105a, and 106a must be recombined.
Therefore, the adjusting bolts 107 and 108, the nut 109,
110 must be removed and re-tightened. Therefore, the applicant filed Japanese Utility Model Application No. 5-33630.
For installation on utility poles to simplify work on poles
Provided band.

[0008]

However, in such a conventional band for attaching a power pole, the power pole 11 has a band member 101, 102 whose length is adjusted in advance.
When trying to attach to the desired height of 2,
If the diameter of the power pole mounting free band does not match the diameter of the power pole 112, the diameter of this band must be corrected.
Removal and tightening of 7, 108 and nuts 109, 110 are performed on a utility pole. Therefore, the correction work is complicated and time-consuming, and it is dangerous to perform such a correction work on a utility pole. Ma
In the device described in Japanese Utility Model Laid-Open Publication No. 3-33030, a T-shaped
Since the head 19a of the bolt 19 is simply a flat plate,
When a load is applied to the hanging hardware 20,

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. As shown in FIGS. 1 and 2, the electric pole mounting free band according to the present invention includes four band members 1, 2, 3, 4 surrounding the outer periphery of the electric pole 5 and the band members 1, 2, 3, 4. It comprises two bolts 6 and nuts 7 connecting one end, and two bolt-shaped connecting members 8 and nuts 9 connecting the other ends of the band members 2, 3, 4, and 5.

As shown in FIGS. 3 to 6, the band member 1 has a shaft hole 10 formed in the left end of the elongated metal plate, a reinforcing recess 14 surrounding the shaft hole 10, and a left end to a right end. Flanges 11 are formed on both sides with a predetermined length over the entire length, and the whole of the flange 11 has a substantially arc shape from a substantially central portion to a right end portion. A plurality of projections 12 are formed at predetermined intervals from the center to the right end of the arc-shaped portion 1a, and adjustment holes 13 are formed in the projections 12. The adjustment hole 13 is generally an oval oval, but may be rectangular.

Next, as shown in FIGS. 7 to 10, the band member 2 has substantially the same configuration as the band member 1, and the arc-shaped portion 2a is directly formed without forming the convex portion 10. A plurality of adjusting holes 15 having the same shape as the adjusting holes 13 are formed at predetermined intervals. Other configurations are the same as those of the band member 1, and the same portions are denoted by the same reference numerals and overlapping description will be omitted.

Therefore, when the arc-shaped portions 1a and 2a of the band members 1 and 2 are overlapped with each other, as shown in FIG. 1, a configuration surrounding half of the utility pole 3 can be formed, and the other half has a symmetric configuration. Can be combined. Therefore, the band member 3 in FIG. 1 has the same configuration as the band member 1, and the band member 4 has the same configuration as the band member 2.

The bolt 6 is a round head bolt. As shown in FIG. 1, between the round head and the threaded portion, a prism portion 6a that fits into the shaft hole 10 and prevents rotation is formed. , The round head can be stably seated outside the concave portion 14 of the band members 1 and 2, and the nut 7 screwed to the bolt 6 is stably positioned outside the concave portion 14 of the band members 3 and 4. The band members 1, 2 and the band members 3, 4 can be fastened so as to be close to each other.

Reference numeral 8 abuts on the long sides of the adjusting holes 13, 15 instead of the arcs. Therefore, the height and width of the contact surface 18 are the arc-shaped portions 1
The dimension is approximately twice the wall thickness of a or 2a.

The operation of connecting or disconnecting the band members 1, 2, 3 and 4 by the connecting member 8 will be described. As shown in FIG. 15, the band members 1 and 2 are superposed. In the arc-shaped portions 1a and 2a,
The adjusting holes 13 and 15 are aligned with each other, and the adjusting holes 13 and 1
5, the flat head 16 is fitted and penetrated, pushed in the axial direction of arrow A, and rotated 90 degrees about the axis in the arc direction of arrow B, and then pulled in the axial direction of arrow C. As shown in FIG. 16, the contact surfaces 18, 18 abut against the long sides 13a, 15a of the adjustment holes 13, 15 to prevent the connecting member 8 from rotating around the axis. With flat head 1
The six arc-shaped portions 16a, 16a come out of the long side portions 13a, 15a to prevent them from falling off. In this state, the nut 9 is screwed into the screw portion 17 and the arc-shaped portions 1a and 2a are fastened to each other, whereby the band members 1 and 2 are connected to each other.

Conversely, when removing the connecting member 8 from the band members 1 and 2 connected as described above, FIG.
First, the nut 9 is unscrewed from the threaded portion 17 and then the connecting member 8 is pushed into the electric pole 5 in the direction of arrow D, and then rotated 90 degrees in the direction of the arc of arrow E about the axis. When the head is pulled out in the direction of the arrow as it is, the flat head 16 enters the adjustment holes 13 and 15, and the connecting member 8 is pulled out at hand.

Therefore, when attaching the power pole mounting free band to the power pole 5, the diameter of the power pole mounting free band is previously assembled as shown in FIG. The length of the band members 1 and 2 may be corrected as described above while climbing the telephone pole 5. Corrected and assembled power pole mounting band is connected
