Abstract

<P>PROBLEM TO BE SOLVED: To prevent the damage of a connection part of a bracket mounting instrument and to prevent the deformation of the bracket or the like to attain time shortening and simplification of restoration work by eliminating a part acting as a fulcrum as well as concentration of force on a part of the bracket mounting instrument even if rotational moment of magnitude exceeding an allowable limit works on the bracket mounting instrument. <P>SOLUTION: A buffer member 36 is wound around the whole periphery of a part, mounted with the cross arm mounting instrument 1, of a side face of a pole P, and the bracket mounting instrument 1 is mounted to the pole P from the outside of the buffer member 36 to interpose the buffer member 36 between the pole P and the bracket mounting instrument 1. Consequently, even if rotational moment of magnitude exceeding the allowable limit works on the bracket mounting instrument 1, the buffer member 36 is distorted in the circumferential direction of the pole P, rotated or damaged, and a bracket Q and the whole bracket mounting instrument 1 are rotated in the same direction as the rotational moment. There is therefore no concentration of force on a part of the bracket mounting instrument 1, nor is force applied to the other part with a certain part as a fulcrum. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  The present invention relates to a shock-absorbing member for preventing damage to a brace attaching device for attaching a brace that protrudes horizontally to a columnar standing body such as a utility pole, and a method for attaching the shock-absorbing member.

  A brace that protrudes in the horizontal direction with respect to a columnar standing body such as a utility pole is connected to the bracelet mounting tool by a connecting portion and is configured integrally with the bracelet mounting tool. The instrument is also fastened to the columnar standing body by a band body or the like and fixed in an immobile state (see, for example, Patent Document 1 and Patent Document 2).

  Therefore, for example, when a fallen tree or the like hits this arm metal due to strong wind or snow damage, as shown in FIG. 8, the arm corresponding to a single arm 102 called a horizontal extension arm I type is used. In the gold mounting instrument 101, when a force acts in the direction of a thick line arrow with the tip 103 of the arm metal 102 as a force point, a rotational moment acts in the direction of the white arrow in the figure, and the two connecting portions 104 and 105, because the force concentrates on the connecting portion 104 and distortion occurs, and a tensile force acts on the connecting portion 105 with the connecting portion 104 as a fulcrum to generate distortion. In particular, the connection portions 104 and 105 of the instrument 101 may be damaged. The same applies to a bracelet mounting tool called a horizontal extension arm type II, a bracelet mounting tool, and the like.

For example, Patent Document 3 discloses that an attempt to solve such a problem that a bracelet mounting instrument is damaged due to a rotational moment acting on the bracelet mounting instrument due to a load from the horizontal direction on the bracelet. The pole for the electric pole shown is already considered. An outline of the power pole band according to Patent Document 3 is as follows. A throttle portion is provided at a bent portion of the band, and a diaphragm outer edge is provided at a predetermined position of the throttle portion, thereby increasing the strength of a portion where force is concentrated. Yes.

  However, the utility poles and braces are made of a material that is difficult to restore to the original shape once they are deformed. However, the provision of the throttle part as in Patent Document 3 above cannot solve the problem that when a fallen tree or the like hits the arm metal, the utility pole or the arm metal is loaded and deformed. . For this reason, in order to recover, the work of exchanging utility poles and armrests is necessary, and there is a problem that the recovery work becomes longer and complicated.

  Therefore, the present invention eliminates a portion where the force concentrates on a part of the bracelet mounting tool and acts as a fulcrum even if a rotational moment is applied to the bracelet mounting tool in a size exceeding the allowable limit value. As a result, damage to the connection part of the bracelet mounting tool was prevented, and columnar standing bodies such as utility poles and bracelets were prevented from being deformed by the load, thereby shortening and simplifying the restoration work. It is an object of the present invention to provide a buffer member for a columnar standing body and a method for attaching the same.

  The buffer member for a columnar standing body according to the present invention comprises a plurality of members that are mounted on the columnar standing body side of a component facing the side surface of the columnar standing body of the armrest mounting instrument, By interposing between the fixture for attachment and the columnar standing body, a part of the side surface of the columnar standing body can be covered (Claim 1). And as a mounting method of the buffer member for the columnar standing body according to the present invention, for one component part facing the side surface of the columnar standing body of the armrest mounting tool, the columnar standing body faces the columnar standing body. The columnar upright body cushioning member is mounted on one side by the engaging means, and the columnar upright body is attached to the other component parts facing the columnar upright body of the armrest mounting tool. After the step of mounting the other constituent members of the columnar standing body cushioning member by the engaging means on the side facing the mounting body, the columnar standing body cushioning member is mounted. A method of covering a part of the side surface of the columnar erected body with the buffer member for the columnar erected body by attaching the brace mounting device to the columnar erected body is adopted (Claim 3). Here, examples of the component parts facing the side surface of the columnar standing body in the brace mounting tool include a band center piece of the band body and an inclination preventing portion of the support member. The buffer member for a columnar standing body is composed of, for example, two constituent members that are made of a weather-resistant polyethylene resin or the like and have an arc-shaped belt shape. The engagement means includes, for example, a through hole provided in the band center piece of the band body, which is a component facing the side surface of the columnar standing body of the armature mounting tool, and the tilt-proof portion of the support member, and the columnar standing body. It is comprised by the projection part which can be fitted to the said through-hole formed in each structural member of a buffer member, and one-touch attachment is possible.

  With such a configuration, even if a rotational moment exceeding the allowable limit is applied to the bracelet mounting device, the bracelet mounting device faces the side surface of the columnar standing body of the bracelet mounting device. Since the cushioning member for the columnar standing body is interposed between the component part and the columnar standing body so as to cover a part of the side surface of the columnar standing body in a necessary and sufficient range, this columnar standing body is provided. Since the body shock-absorbing member is distorted, rotated, or damaged in the circumferential direction of the utility pole, the entire bracelet mounting device can be rotated in the same direction as the rotational moment. The force does not concentrate, and a certain part serves as a fulcrum and no force acts on other parts. In addition, since the brace also rotates together with the brace attachment device, a large load is not applied to the utility pole or bracelet.

  Further, the buffer member for a columnar standing body according to the present invention is composed of a single member that is mounted on a portion of the columnar standing body on which a brace mounting instrument is to be mounted. By interposing between the upright bodies, the entire circumference of the side surface of the columnar upright body can be covered (Claim 2). And as a mounting method of the buffer member for the columnar standing body according to the present invention, after mounting the buffer member for the columnar standing body on the portion of the columnar standing body where the brace mounting device is mounted, A method of covering the entire periphery of the side surface of the columnar standing body with the buffer member for the columnar standing body by attaching a brace mounting device to the columnar standing body from the outside of the buffering member for the columnar standing body. (Claim 4). Here, examples of the component parts facing the side surface of the columnar standing body in the brace mounting tool include a band center piece of the band body and an inclination preventing portion of the support member. The columnar standing body buffer member is made of, for example, a weather-resistant polyethylene resin as a material, and has a strip-like shape of a single thin plate. The engaging means are formed in a plurality of rows on the other end side in the longitudinal direction of the columnar standing body buffer member, and the protrusion formed on one end side in the longitudinal direction of the buffer member for columnar standing body, And a through-hole into which the protrusion can be fitted.

  According to such a configuration, even if a rotational moment exceeding a permissible limit is applied to the bracelet mounting device, the bracelet mounting device connected to the bracelet is columnar in the bracelet mounting device. Since the columnar standing body buffer member is interposed between the component facing the side surface of the standing body and the columnar standing body so as to cover the entire circumference of the side surface of the columnar standing body, this columnar shape Since the cushioning member for standing body itself is distorted, rotated, or damaged, it becomes possible to rotate the entire bracelet mounting device in the same direction as the rotational moment. In other words, the force does not concentrate on the other part, and the force does not act on another part as a fulcrum. In addition, since the brace also rotates together with the brace attachment device, a large load is not applied to the utility pole or bracelet.

  As described above, according to the first and third aspects of the present invention, even if a rotational moment exceeding the allowable limit is applied to the bracelet mounting device, the bracelet mounting portion connected to the bracelet is attached. The instrument covers the side surface of the columnar standing body within a necessary but sufficient range between the component facing the side surface of the columnar standing body and the columnar standing body of the brace mounting instrument. Thus, the columnar standing body cushioning member is interposed, so that the columnar standing body cushioning member is distorted, rotated, or damaged in the circumferential direction of the electric pole, so that the entire brace mounting device has a rotational moment. It becomes possible to rotate in the same direction. For this reason, the force is not concentrated on a part of the bracelet attaching device, and the force does not act on other parts as a fulcrum, so the bracelet attaching device is damaged. Can be prevented.

  In addition, according to the first and third aspects of the invention, it is difficult for the load due to the rotational moment to be transmitted to the columnar standing body such as the utility pole, so that the columnar standing body such as the utility pole is prevented from being deformed. At the same time, since the arm is also rotated together with the device for attaching the arm, no load is applied to the arm, so that the arm is prevented from being deformed by the load. Along with this, there is no need to replace a columnar standing body such as a power pole or a brace, so that the restoration work can be shortened and simplified.

  Moreover, according to the first and third aspects of the present invention, since existing columns can be used as they are for column-like standing bodies such as utility poles, braces, and bracelets, the cost increases. Even if the brace mounting device rotates in the circumferential direction with respect to the columnar standing body such as an electric pole due to breakage of the buffering member for the columnar standing body, the buffer member for the columnar standing body can be suppressed. After removing the structural member from between the armrest mounting device and the columnar standing body such as a utility pole, rotate the armature mounting device to the original position, and then fix it to the columnar standing body with a fixture. As a result, it can be restored to a usable state at an early stage, and the restoration work is also simple.

  According to the invention described in claim 2 and claim 4, even if a rotational moment exceeding a permissible limit is applied to the bracelet mounting instrument, the bracelet mounting instrument is a part of the bracelet mounting instrument. Since the columnar standing body cushioning member is interposed between the component facing the side surface of the columnar standing body and the columnar standing body so as to cover the entire circumference of the side surface of the columnar standing body, this Since the buffer member for the columnar erected body is distorted, rotated or damaged in the circumferential direction of the utility pole, the entire bracelet mounting device can be rotated in the direction of the rotational moment. Since the force does not concentrate on a part of the mounting tool and the force does not act on other parts as a fulcrum, it can prevent the arm mounting tool from being damaged. it can.

  Also, in the inventions according to claim 2 and claim 4, since the load due to the rotational moment is hardly transmitted to the columnar standing body such as the utility pole, the deformation of the columnar standing body such as the utility pole is avoided. In addition, since the arm is also rotated together with the arm bracket mounting tool, no load is applied to the arm, so that the arm is prevented from being deformed by the load. Along with this, there is no need to replace a columnar standing body such as a power pole or a brace, so that the restoration work can be shortened and simplified.

  In the inventions according to claim 2 and claim 4 as well, it is possible to use the existing column-like standing bodies such as utility poles, braces, and brace fittings as they are, so that the increase in cost is suppressed. Even if the armrest mounting device rotates in the circumferential direction with respect to the columnar standing body such as a power pole due to the damage of the buffering member for the columnar standing body, the cushioning member for the columnar standing body is It can be used by pulling it out between the armrest mounting device and the columnar standing body such as a utility pole, rotating the armrest mounting device to its original position, and then fixing it to the columnar standing body with a fixture It is possible to quickly recover to a safe state, and the recovery work is also simple.

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

  FIGS. 1 to 3 show an example corresponding to a single-use brace fitting instrument 1 in the first embodiment of the present invention. In the following, the brace fitting device 1 will be described as being used for the utility pole P. However, it is not necessarily limited to the utility pole P, and even a pillar-like standing body such as a telephone pole, a street light pole, an advertising pillar, etc. Any arm that has a brace protruding in the horizontal direction with respect to the structure can be used. In the first embodiment, which will be described later, the holding arm mounting tool 1 in the second embodiment, the single arm mounting tool 1 and the holding arm mounting tool 1 in the second embodiment, The same applies to.

  As shown in FIG. 3, this single-use brace mounting instrument 1 has support members 2 and 2 each having an inclination preventing portion 5 that can simultaneously contact the side surface of the utility pole P, and a brace Q attached to the utility pole P. A clamping part 3 as a first clamping means for clamping from both sides in the axial direction, a clamping device 4 as a second clamping means for clamping the arm metal Q from both radial sides of the utility pole P, and its main The contact portion with the electric pole P is basically constituted by a band body 6 positioned on the opposite side of the radial direction of the electric pole P with respect to the support member 2.

  Among these members, the support members 2 and 2 are arranged side by side along the axial direction of the armature Q that is a rectangular parallelepiped, for example, and this support member 2 is provided with an arm for preventing the electric pole P from tilting. On the side opposite to the gold Q, it is bent in a substantially V shape and has an anti-tilt portion 5. The interval between the inclination prevention part 5 and the inclination prevention part 5 is set so that both the inclination prevention parts 5 and 5 and the vicinity thereof are located on the circumference of the utility pole P. Furthermore, each inclination prevention part 5 is formed with a plurality of (two in this embodiment) through-holes 34 through which protrusions 33 of constituent members 26 of the buffer member 24 described later are inserted and engaged.

  The band body 6 includes a band center piece 7 that comes into contact with the side surface of the utility pole P, and tightening pieces 8 and 8 that are located on both sides of the band center piece 7 in the longitudinal direction. Each of the tightening pieces 8 has a plurality of through holes 9. For example, after the bolts 10 attached to the band center piece 7 are inserted into the through holes 9, the nuts 11 are externally fastened to the bolts 10. The central piece 7 and the fastening pieces 8 and 8 are connected. Then, by shifting the position of the through hole 9 through which the bolt 10 is inserted, the band center piece 7 can come into contact with the side surface of the contact power pole P even if the diameter of the power pole P is slightly different. ing. Further, the portion of the tightening pieces 8, 8 on the side opposite to the band center piece 7 is fixed to the support member 2 via a fixing tool 12 including a bolt 13 and a nut 14. Further, the band center piece 7 is formed with a through hole 29 into which a protruding portion 28 of a constituent member 25 of the buffer member 24 described later is inserted and engaged.

  The sandwiching portion 3 extends along the radial direction of the utility pole P on the side opposite to the tilt-proof portion 5 with respect to the support members 2 and 2. In this embodiment, the sandwiching portion 3 is against the side surface of the support member 2. It is configured to have two standing portions 15 and 15 erected in a substantially orthogonal direction and a connecting portion 16 positioned between the erected portions 15 and 15. The distance between the standing portion 15 and the standing portion 15 is substantially the same as the dimension in the short direction of the arm metal Q and in the axial direction of the utility pole P.

  The clamping device 4 includes a clamping plate 17 having an abutting surface capable of contacting the side surface of the arm metal Q, a rod 18 into which the clamping plate 17 is externally inserted, and the clamping plate 17 from being removed from the rod 18. It is comprised from the nut 19 which carries out. In this embodiment, the rod 18 protrudes through the connecting portion 16 of the sandwiching portion 3 and is threaded so that at least a tip portion thereof is screwed with the nut 19. As a result, the arm metal Q can be sandwiched between the contact surface of the sandwiching plate 17 and the surface of the connecting portion 16 of the sandwiching portion 3 from the radial direction of the utility pole P. The distance to the surface of the connecting portion 16 is determined by adjusting the position where the nut 19 is extrapolated to the rod 18.

  Further, as shown in FIG. 3, a buffer member 24 is interposed between the brace mounting device 1 and the utility pole P. The buffer member 24 is composed of a plurality of members, that is, a component member 25 and a component member 26, each of which is formed of a weather-resistant polyethylene resin. For example, a high-pressure retaining crank cover is processed and reused. It has become.

  Among these, the component member 25 is attached to the band center piece 7 of the band body 6 of the arm bracket attachment instrument 1 and, as shown in FIG. The plate-like portion 27 is configured to have a single protrusion 28 protruding from the center in the longitudinal direction of the surface in contact with the band center piece 7. The curvature of the plate-like portion 27 is substantially the same as the curvature of the side surface extending in the axial direction of the utility pole P. In addition, as shown in FIGS. 1A and 1B, both edges along the longitudinal direction of the plate-like portion 27 protrude outward from the central portion and are relatively relative to the central portion. Thick ridges 30. Thus, by having the raised portion 30, simplification of attachment of the component member 25 to the band center piece 7 and attachment of metal fittings is achieved. Further, as shown in FIG. 1A, the projection 28 has a shaft portion substantially the same as the through-hole 29 of the band center piece 7 and a head larger than the through-hole 29. By engaging the peripheral portion of the hole 29, the component member 25 is prevented from coming off from the band center piece 7.

  The component member 26 is attached to the tilt-proof portion 5 of the support member 2 of the arm bracket attachment instrument 1 and has a thin arc plate-like plate-like portion 31 as shown in FIG. And as for this plate-shaped part 31, both the edges along the longitudinal direction protrude toward the outer side rather than the center part, as FIG. 2 (a) and FIG.2 (b) show, rather than the said center part. In addition to having a relatively thick raised portion 32, it has four protruding portions 33 that protrude further outward in the vicinity of both ends of the raised portion 30 in the longitudinal direction. Thus, by having the raised portion 32, simplification of attachment of the component member 26 to the tilt-proof portion 5, attachment of a metal fitting, and the like is achieved. Further, the curvature of the plate-like portion 31 is substantially the same as the curvature of the side surface extending in the axial direction of the utility pole P. Further, as shown in FIGS. 2A to 2C, the protrusion 33 has a shaft portion substantially the same as the through-hole 34 of the tilt-proof portion 5 and a head larger than the through-hole 34. Since the head engages with the peripheral portion of the through hole 34, the component member 26 is prevented from coming off from the inclination preventing portion 5.

  Next, a procedure for attaching the constituent members 25 and 26 constituting the buffer member 24 to the single-use armband attaching instrument 1 will be described. As for the component member 25, the protruding portion 28 is press-fitted into the through hole 30 of the band center piece 7 from the utility pole P side, and the outer side surface of the plate-like portion 27 and the protruding side surface of the raised portion 30 are placed on the side of the utility pole P of the band center piece 7. Make contact. With respect to the component member 26, the protrusion 33 is press-fitted into the through hole 34 of the inclination preventing portion 5 from the utility pole P side, and the outer surface of the plate-like portion 31 and the protruding side surface of the raised portion 32 are brought into contact with the apex portion of the inclination preventing portion 5. Make contact. Then, the brace mounting instrument 1 is assembled to the utility pole P in a state where the constituent member 25 is attached to the band center piece 7 and the constituent member 26 is attached to the tilt-proof portion 5 of the support member 2.

  As a result, even if a fallen tree or the like hits the arm metal Q and a rotational moment exceeding the allowable limit is applied to the arm metal mounting apparatus 1, the arm metal mounting apparatus 1 is configured so that the band center piece 7 and the electric pole P Since the buffer member 24 is interposed between the inclination preventing portion 5 of the support member 2 and the utility pole P, and the utility pole P and the brace mounting instrument 1 are not in a fixed state, the cushion member Since 24 is distorted, rotated, or damaged in the circumferential direction of the utility pole P, the entire brace mounting instrument 1 can be rotated in the same direction as the rotational moment with respect to the utility pole P. The force is dispersed with respect to 1 so that the force does not concentrate on a part of the brace attachment device 1 and the force does not act on another part as a fulcrum. In addition, even if a rotational moment is applied to the arm metal Q, the arm metal Q is rotated together with the arm hardware attaching device 1 and no load is applied to the arm metal Q. Therefore, the arm metal Q is deformed by the load. It is avoided.

  FIG. 4 shows a modification corresponding to the holding arm mounting tool 1 in the first embodiment of the present invention. This bracelet mounting instrument 1 includes two pairs of support members 2 and 2, a clamping part 3 as a first clamping unit for clamping the bracelet Q from both sides in the axial direction of the utility pole P, and the bracelet Q. It is basically configured with a clamping device 4 as second clamping means for clamping from the both radial sides of the utility pole P.

  The support members 2 and 2 are, for example, points arranged side by side along the axial direction of the armature Q that forms a rectangular parallelepiped, the inclination preventing portions 5 that are disposed at intervals that can simultaneously contact the side surfaces of the utility pole P, 5 and a plurality of (two in this embodiment) through-holes 34 through which the protrusions 33 of the component member 26 of the buffer member 24 are inserted and engaged with each of the tilt-proof portions 5 are formed. This is similar to the example shown in FIG.

  Further, the sandwiching portion 3 extends along the radial direction of the utility pole P on the side opposite to the tilt-proof portion 5 with respect to the support members 2 and 2, and a direction substantially orthogonal to the side surface of the support member 2. The two erected parts 15, 15, and the connecting part 16 positioned between the erected parts 15, 15, and the erected part 15 and the erected part 15. Is the same as the example shown in FIG. 3 in that the distance between and is substantially the same as the dimension along the axial direction of the utility pole P.

  Further, with respect to the clamping member 4, the clamping plate 17 having a contact surface capable of contacting the side surface of the arm metal Q, the rod 18 on which the clamping plate 17 is extrapolated, and the clamping plate 17 fall off from the rod 18. This is similar to the example shown in FIG. 3 in that the nut 19 is configured to prevent this.

  That is, the brace mounting instrument 1 shown in FIG. 4 is the same as the example shown in FIG. 3 except that it does not have the band body 6 and the support member 2 or the like is used instead. 2, detailed description of the configuration of the clamping unit 3 and the clamping device 4 is omitted by giving the same reference numerals as in the example of FIG.

  On the other hand, the support member 2 of the bracelet mounting instrument 1 is formed with a through-hole 20, and the through-holes 20 and 20 of the support members 2 and 2 facing each other with the electric pole 9 of the bracelet mounting instrument 1 sandwiched between , Located on the same axis. As a result, as shown in FIG. 4, the rods 21 can be inserted through the through holes 20 of the support members 2 and 2 that ridge each other, and the rods 21 are all parallel. The total length of the rod 21 in the axial direction is larger than the dimension between the support members 2 and 2 facing each other of the arm bracket attachment instrument 1.

  Accordingly, when the nut 22 is extrapolated from the side opposite to the side having the head with respect to the rod 21, the distance between the nut 22 and the rod 21 is changed by varying the distance between the support members 2 and 2. Can be varied.

  On the other hand, as shown in FIG. 4, a buffer member 24 is interposed between the brace mounting device 1 and the utility pole P. The buffer member 24 includes two constituent members 26 and 26. The component member 26 is a member that is attached to the tilt-proof portion 5 of the support member 2 of the armrest attachment device 1 shown in FIG. 2 or is formed of a weather-resistant polyethylene resin. This is similar to the example shown in FIG. 3 in that the retaining crank cover is processed and reused. For this reason, the detailed description of the structural member 26 is omitted.

  Next, a procedure for attaching the constituent members 26 and 26 constituting the buffer member 24 to the single-use arm bracket attaching instrument 1 will be described. Each component member 26 press-fits the projecting portion 33 into the through hole 34 of the tilt-proof portion 5 from the utility pole P side, and contacts the outer side surface of the plate-like portion 31 and the protruding side surface of the raised portion 32 against the apex portion of the tilt-proof portion 5. Make contact. Then, the brace mounting device 1 is assembled to the utility pole P in a state in which the component member 26 is attached to the tilt-proof portion 5 of each support member 2.

  As a result, even if a fallen tree or the like hits the armor Q and a rotational moment exceeding the allowable limit acts on the armor mounting instrument 1, the armrest mounting instrument 1 is not inclined to the support member 2. Since the buffer member 24 is interposed between the power pole 5 and the utility pole P, and the utility pole P and the bracelet mounting device 1 are not fixedly fixed, the cushion member 24 is distorted in the circumferential direction of the utility pole P. Rotating or damaging the whole armrest attaching device 1 allows the armature attaching device 1 to rotate in the same direction as the rotational moment with respect to the utility pole P. The force does not concentrate on a part of the gold mounting device 1 and the force does not act on another part as a fulcrum. In addition, even if a rotational moment is applied to the arm metal Q, the arm metal Q is rotated together with the arm hardware attaching device 1 and no load is applied to the arm metal Q. Therefore, the arm metal Q is deformed by the load. It is avoided.

  In FIG.5 and FIG.6, the example corresponding to the single brace attachment instrument 1 among 2nd Embodiment of this invention is shown. However, since the configuration of the single-use arm bracket mounting instrument 1 is the same as the example shown in FIG. 3, the configuration of the arm bracket mounting instrument 1 is the same as the example shown in FIG. The description will be omitted, and a description will be given below centering on the buffer member 36 different from the example shown in FIG.

  The shock-absorbing member 36 is a single member and is formed of a weather-resistant polyethylene resin. For example, a high-pressure retaining crank cover is processed and reused. And this buffer member 36 is wound around the side surface of the utility pole P, and is an elongated thin plate-like plate-like portion 37 and two protrusions formed in the vicinity of one end in the longitudinal direction of this plate-like portion 37. 38 and each of the five through holes 39 formed in the vicinity of the other end in the longitudinal direction of the plate-like portion 37 and arranged in parallel along the longitudinal direction of the plate-like portion 37. Yes.

  Among them, the through hole 39 has an inner diameter dimension substantially the same as the thin shaft portion of the projection portion 38 and a slit extending from the periphery of the hole so that the head portion of the projection portion 38 can be inserted. Yes. In this way, by forming a plurality of through holes 39 along the longitudinal direction of the plate-like portion 37, the buffer member 36 is wound around the utility poles P having different diameters, and then the protruding portions 38 are inserted into the predetermined through holes 39. By fitting, both end sides of the buffer member 36 can be coupled.

  Further, the plate-like portion 37 protrudes toward the outside of the other portion on the short side and on the lower side in the axial direction when mounted on the utility pole P, and is more relative to the other portion. A thick ridge 40 is provided. The raised portion 40 makes it easy to fix the band body 6 of the brace mounting instrument 1.

  Next, an attachment procedure between the buffer member 36 and the single arm bracket attachment instrument 1 will be described. A plate-like portion 37 of the buffer member 36 is provided on a portion of the side surface of the utility pole P to which the arm bracket attachment device 1 is attached, and for example, the protrusion 38 of the plate-like portion 37 is provided with the protrusion 38 facing outward. While holding the end side on the side surface of the utility pole P, the end side having the through-hole 39 of the plate-like portion 37 is pulled to the end side having the projecting portion 38 of the plate-like portion 37, and the most opposite end portion among the plurality of through-holes 39 The through hole 39 on the side is extrapolated to the protrusion 38. Thereby, the buffer member 36 is mounted in a state of being tightened to the side surface of the utility pole P. Next, the single brace mounting instrument 1 is placed on the outer side of the buffer member 36 such that the inner surface of the band central piece 7 of the band body 6 and the inclination preventing portion 5 of the support member 2 abut against the buffer member 36. Wear from.

  As a result, even if a fallen tree or the like hits the arm metal Q and a rotational moment exceeding the allowable limit is applied to the arm metal mounting apparatus 1, the arm metal mounting apparatus 1 is configured so that the band center piece 7 and the electric pole P Since the buffer member 36 is interposed between the inclination preventing portion 5 of the support member 2 and the utility pole P, and the utility pole P and the bracelet mounting instrument 1 are not in a fixed state, the cushion member Since 36 is distorted, rotated, or damaged in the circumferential direction of the utility pole P, the entire brace mounting instrument 1 can be rotated in the same direction as the rotational moment with respect to the utility pole P. The force is dispersed with respect to 1 so that the force does not concentrate on a part of the brace attachment device 1 and the force does not act on another part as a fulcrum. In addition, even if a rotational moment is applied to the arm metal Q, the arm metal Q is rotated together with the arm hardware attaching device 1 and no load is applied to the arm metal Q. Therefore, the arm metal Q is deformed by the load. It is avoided.

  FIG. 7 shows a modified example corresponding to the holding arm mounting tool 1 in the second embodiment of the present invention. However, since the configuration of the holding arm 1 is similar to the example shown in FIG. 4, the configuration of the mounting device 1 is the same as the example shown in FIG. The description is omitted. Moreover, since the buffer member 36 interposed between the utility pole P and the inclination prevention part 5 of the support member 2 is the same as that shown in FIG. 5, the configuration of the buffer member 36 is also the same as the example shown in FIG. The same reference numerals are given and the description thereof is omitted.

  Accordingly, the plate-like portion 37 of the buffer member 36 is placed on the portion of the side surface of the utility pole P where the arm bracket attachment device 1 is attached. The side having the through holes 39 of the plate-like portion 37 is pulled to the side having the projections 38 of the plate-like portion 37 while holding the side having the pole on the side surface of the utility pole P, and the most end side of the plurality of through holes 39 is pulled. The procedure of extrapolating the through-hole 39 to the protrusion 38 is the same as in the example of FIG. Then, the procedure for mounting the single-use arm bracket mounting instrument 1 for holding from the outside of the buffer member 36 so that the tilt-proof portion 5 of each support member 2 contacts the buffer member 36 is shown in the previous figure. This is different from the 6 example.

  Accordingly, even in the example shown in FIG. 7, even when a fallen tree or the like hits the arm metal Q and a rotational moment exceeding the allowable limit is applied to the arm hardware mounting instrument 1, Since the shock absorber 36 is interposed between the inclination prevention part 5 of the support member 2 and the utility pole P, the utility tool 1 is not in a state in which the utility pole P and the bracelet mounting instrument 1 are not fixed in a stationary manner. Since the buffer member 36 is distorted, rotated, or damaged in the circumferential direction of the utility pole P, the entire brace mounting instrument 1 rotates in the same direction as the rotational moment with respect to the utility pole P. The force is distributed and the force is not concentrated on a part of the brace attaching instrument 1 and the force does not act on another part as a fulcrum. In addition, even if a rotational moment is applied to the arm metal Q, the arm metal Q is rotated together with the arm hardware attaching device 1 and no load is applied to the arm metal Q. Therefore, the arm metal Q is deformed by the load. It is avoided.
