  On the other hand, if the strength of the electric wire support of Patent Document 1 is increased to such an extent that it can be used as a scaffold, the weight of each member of the electric wire support increases, and the work of attaching the electric wire support to the utility pole or the utility pole There is a concern that the removal work from the plant becomes complicated and takes a long time.

  Moreover, the electric wire support of the said patent document 2 assumes what is fundamentally attached to the flat surface of each member of a steel tower, and is a structure for attaching the through-hole which can insert a locking bolt. If the structure to be mounted is a cylindrical body and the mounting surface is a curved surface, the distance between the radial ends of the wire support and the structure is required. There is a problem that a large gap is generated in the wire and the electric wire support rattles. Furthermore, since the two members that sandwich the electric wire of the electric wire support of Patent Document 2 are also connected by bolts or the like, man-hours are required.

  Therefore, the present invention can simplify the mounting and removal work of a support for a linear body such as an electric wire, shorten the time, and can use an existing one as it is for a columnar standing body and a fastener. Furthermore, it is an object of the present invention to provide a structure for holding a linear body to a columnar standing body and a method for holding the same, which prevents rattling after the support tool is attached to the columnar standing body such as an electric pole.

The support tool includes a first sandwiching member and a second sandwiching member for sandwiching the linear body, and a wire sandwiched between the first sandwiching member and the second sandwiching member. And a variable mechanism that is variable in a direction approaching and separating from the cylindrical body, and at least the columnar standing body side of the first clamping member and the second clamping member constituting the support. The object can be deformed so that the surface on the columnar standing body side is the same as the curvature of the curved surface of the columnar standing body, and the linear body is sandwiched between the first clamping member and the second clamping member. The support is mounted on the curved surface of the columnar standing body while being sandwiched between the members. In addition, the support and the columnar standing body are fastened from the outside in the radial direction of the columnar standing body by a fastener surrounding the columnar standing body. (Claim 1).

Moreover, the holding structure of the linear body to the columnar standing body according to the present invention is a structure for holding the linear body on the columnar standing body by attaching a support to the curved surface of the columnar standing body having a curved surface. Because
The support is composed of a first sandwiching member and a second sandwiching member for sandwiching the linear body, and a linear body sandwiched between the first sandwiching member and the second sandwiching member.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIGS. 1 to 5 show an example of a support 1 constituting the main structure of the structure for holding a linear body to a columnar standing body according to the present invention. The support 1 will be described below as being used for the utility pole 22, but is not necessarily limited to the utility pole 22, and can also be used as a columnar standing body such as a telephone pole, a street light pole, an advertisement pole, or the like. Moreover, although the object clamped with the support tool 1 is the electric wire 21, especially the electric wire 21 which comprises a low voltage | pressure pull-up line or a low voltage pull-down line, it is not necessarily limited also about this, A plurality of things are pillar-shaped like the electric pole 22 grade | etc., The present invention can be used if it is a linear body that needs to be held by a standing body.

  The support 1 has a substantially rectangular parallelepiped shape made of a synthetic resin material such as plastic, and has a flexibility that can be deformed so that its longitudinal direction substantially follows the curved surface of the utility pole 22. ing. And this support tool 1 has the 1st clamping member 2 used as the utility pole 22 side, and has the 2nd clamping member 3 which presses the electric wire 21 to the utility pole 22 side, and is comprised.

It is good also as a structure attached to the edge part of the longitudinal direction of 2 clamping members 3. FIG.

  Further, on the other end side in the longitudinal direction of the support 1, the first holding member 2 and the second holding member 3 are engaged to temporarily hold the closed state when the first holding member 2 and the second holding member 3 are completely closed. As an example of the means, a lock mechanism 14 is provided. The lock mechanism 14 is also known, and its configuration will be described. As shown in FIGS. 2 and 3, the second holding member 3 has a substantially U-shaped groove 15 formed therein, and The one clamping member 2 is formed with a substantially U-shaped engagement piece 16 that is engaged in the groove 15. By rotating the engaging piece 16 to engage with the groove portion 15, the first holding member 2 and the second holding member 3 are temporarily held so as not to open and close, and the engaging piece 16 is turned. Thus, the temporary holding of the first clamping member 2 and the second clamping member 3 is also released by removing it from the groove portion 15. Note that, contrary to the configuration described above, the groove portion 15 may be provided in the first holding member 2 and the engaging piece 16 may be provided in the second holding member 3.

  Further, the configuration of the lock mechanism 14 is not limited to the above-described one, and as shown in FIG. 4, for example, the second clamping member 2 protrudes from the end thereof toward the first clamping member 3 side. An engagement piece 18 whose tip is a key claw is provided, and the engagement piece 18 can be engaged with the first holding member 3 in a state where the first holding member 2 and the second holding member 3 are closed. A groove portion 19 having an inner shape may be provided.

  In FIG. 5, a free band 23 is shown as an example of a fastener that holds the support 1 on the utility pole 22 side. This universal band 23 is a well-known band base piece 24, 24 having a substantially band shape, one end connected to one end of the band base piece 24, and the other end connected to each other by a fixture 26. The fastening pieces 25, 25, and a plurality of through holes, and a band-shaped band adjusting piece 27 connected by a band base piece 24 and a fixture 28 are configured. By changing the position where the fixing tool 28 is inserted and fixed in the through hole of the band adjusting piece 27, the entire circumference of the free band 23 can be adjusted, and by tightening the fixing tool 26, the band base piece 24 and the band adjusting piece 27 can be adjusted. Thus, the support 1 disposed on the inner side can be fastened to the utility pole 22 side.

  Next, the following method is mentioned as an example of the holding | maintenance method of the electric wire 21 to the utility pole 22 using the support 1 and the flexible band 23 of the said structure.

It operates so that it may interpose between the recessed part 4 of the 1st clamping member 2, and the recessed part 4 of the 2nd clamping member 3. FIG.

  Next, by moving the hinge portion 7 in the direction opposite to the previous direction, the first holding member 2 and the second holding member 3 are formed with the through-hole 5 of the support 1 in FIG. Relatively approach to the state. Thereby, since the dimension of the support tool 1 in the width direction of the through hole 5 is smaller than the diameter dimension of the electric wire 21, the electric wire 21 is first pressed into the through hole 5 of the support tool 1 on the inner surface thereof. Is sandwiched between the second clamping member 2 and the second clamping member 3. And the state by which the electric wire 21 was clamped by the 1st clamping member 2 and the 2nd clamping member 3 by the locking mechanism 14 is maintained.

  Furthermore, the support tool 1 is brought into contact with a predetermined position on the side surface of the utility pole 22 with the surface along the longitudinal direction of the first sandwiching member 2 such that the first clamping member 2 is on the utility pole 22 side. State. Furthermore, as shown in FIG. 5, the free band 23 is attached to the utility pole 22. In this case, the universal band 23 is wound further from the outside in the radial direction of the utility pole 22 than the support tool 1 so that the band adjusting piece 27 is also in contact with the surface of the second holding member 3 of the support tool 1 along the longitudinal direction. Finally, by tightening the fixture 26, a force acts on the support 1 along the center direction of the utility pole 22, that is, along the substantially short direction of the support 1, so that the support 1 is made of plastic or the like and is flexible. Since both ends of the longitudinal direction away from the power pole 22 of the support 1 are bent toward the power pole 22, the support 1 is substantially along the side surface of the power pole 22 in the longitudinal direction. It becomes.

  As a result, the four electric wires 21 are held on the side surfaces of the utility pole 22. In addition, since the support tool 1 is formed of a lightweight material such as plastic, the work of attaching and removing the support tool 1 can be simplified and shortened, so that the workability can be improved. . Moreover, since the support tool 1 is installed so that it may follow the side surface of the utility pole 22, it can also prevent that the support tool 1 produces shakiness.

  The fastener is not limited to the free band 23 shown in FIG. 5, and a stainless steel band 30 as shown in FIG. 6 may be used. This stainless steel band 30 is a well-known one and has a belt shape with a plurality of through holes, and is provided at one end in the longitudinal direction of the stainless steel band 30 so that the stainless steel band 30 can be inserted therethrough. And a locking piece 32 that is provided at the other end in the longitudinal direction of the stainless steel band 30 and can be inserted into the through hole of the stainless steel band 30 and locked. . As a result, the stainless steel band 30 having a simplified structure compared to the free band 23 shown in FIG. 5 is used as the fastener, so that the cost can be reduced.

Hereafter, the structure of this support tool 1 is demonstrated using FIG.7 and FIG.8. However, the same components as those of the support 1 shown in FIG.

  The support 1 is the same as the previous example in that it is composed of the first clamping member 2 and the second clamping member 3, but the surface along the longitudinal direction of the first clamping member 2 is attached to the power pole to which it is attached. It is a concave curved surface having substantially the same curvature as the 22 side surfaces. Further, the surface along the longitudinal direction of the second holding member 3 is also a convex curved surface in order to facilitate winding of the band adjusting piece 27 of the free band 23 and the stainless steel band 30. Furthermore, the variable mechanism of the support 1 uses an elastic member 33 such as rubber that connects the opposing surfaces of the first clamping member 2 and the second clamping member 3. However, the hinge portion 7 shown in FIG. Conversely, also in the support 1 shown in FIG. 1 and the like, this elastic member 33 may be used instead of the hinge portion 7. Also in this support 1, the lock mechanism 14 including the engagement piece 18 and the groove 19 shown in FIG. 4 is used instead of the lock mechanism 14 including the groove 15 and the engagement piece 16 shown in FIG. 3. May be.

  Note that, as a fastener for holding the support 1 on the electric pole 22 side, for example, a free band 23 shown in FIG. 5, a stainless steel band 30 shown in FIG. 6, or the like is used.

  Next, the following method is mentioned as an example of the holding | maintenance method of the electric wire 21 to the utility pole 22 using the support 1 and the flexible band 23 of the said structure. That is, as shown in FIG. 8, first, the first holding member 2 and the second holding member 3 are opened by extending the telescopic member 33, and then the four electric wires 21 are connected to the first electric wire 21. It operates so that it may interpose between the recessed part 4 of the 2nd clamping member 3, and the recessed part 4 of the 2nd clamping member 3.

  Next, by stopping the pulling on the expansion / contraction member 33 and moving the hinge portion 7 in the direction opposite to the previous direction by the restoring force of the expansion / contraction member 33, the first holding member 2 and the second holding member 3 are moved. 7 until the through hole 5 of the support 1 of FIG. 7 is formed. Thereby, the electric wire 21 is clamped by the first clamping member 2 and the second clamping member 3 while being pressed by the inner surface of the through hole 5 of the support 1. And the state by which the electric wire 21 was clamped by the 1st clamping member 2 and the 2nd clamping member 3 by the locking mechanism 14 is maintained.

  Furthermore, the support tool 1 is in a state in which the first holding member 2 is on the power pole 22 side, and the surface along the longitudinal direction of the first holding member 2 is in contact with the side surface of the power pole 22. Furthermore, the free band 23 is attached to the utility pole 22 as in the previous example shown in FIG. In this case, the universal band 23 is wound further from the outside in the radial direction of the utility pole 22 than the support tool 1 so that the band adjusting piece 27 is also in contact with the surface of the second holding member 3 of the support tool 1 along the longitudinal direction. Finally, by fastening the fixture 26, the book electric wire 21 is held on the side surface of the utility pole 22.
