[First Embodiment]
With reference to FIG. 1 thru | or FIG. 6, the protection tube suspension apparatus 100 of 1st Embodiment which is one Embodiment of this invention is demonstrated.

  The protection tube suspending device 100 of this embodiment is installed at a high place with respect to one or a plurality of utility poles or structures, and for example, suspends wiring materials such as communication wires in the air. FIG. 1 is a perspective view of a protective tube suspending device 100 of the present embodiment. 2A and 2B are a front view and a side view of the protective tube suspending device 100, respectively. FIG. 3 is a cross-sectional view taken along line AA and BB of the protective tube hanging device 100.

  As shown in FIGS. 1 and 2, the protective tube suspending device 100 includes a messenger wire 110 installed in the longitudinal direction, supported by the messenger wire 110, and a wiring / pipe material (not shown) inside. The protective tube 120 is provided, and a band body 130 as a coupling means for integrally coupling (or coupling) the protective tube 120 and the messenger wire 110 along the longitudinal direction. The protective tube 120 is linearly attached to the messenger wire 110 by a guide portion (accommodating groove 124) formed in the protective tube 120. Hereinafter, each component of the protection tube suspension apparatus 100 of this embodiment will be described in detail.

  The messenger wire 110 is a long body stretched linearly in the long direction. As shown in FIG. 1, the messenger wire 110 includes a steel shaft portion 111 as a core material and a soft synthetic resin coating portion 112 that covers the shaft portion 111. The shaft portion 111 is configured by bundling a plurality of steel wires and has sufficient strength. The covering portion 112 has a thickness that the band body 130 can bite into. For example, the messenger wire 110 can be stretched in the air with both ends fixed to a utility pole (not shown). Alternatively, one end of the messenger wire 110 is fixed to a utility pole, and the other end is fixed to another structure such as a building so that the messenger wire 110 is stretched in the air. The messenger wire 110 has a length erected between structures such as utility poles, but the length is arbitrarily determined. Further, the messenger wire 110 is configured with a diameter capable of exhibiting sufficient strength upon installation, but the diameter is arbitrarily determined.

  The protective tube 120 is a corrugated tube made of a flexible synthetic resin that extends in the longitudinal direction. That is, the protective tube 120 has flexibility that can be wound or bent. FIG. 4 is a perspective view of the protective tube 120. As shown in FIG. 4, the protective tube 120 has a tube wall 121 having a predetermined thickness, and crest portions 122 and trough portions 123 are alternately continuous in the longitudinal direction on the tube wall 121. In addition, the length and diameter of the protective tube 120 are arbitrarily determined according to the diameter or length of the wiring / pipe material disposed inside. In addition, the distance between the outer surface of the mountain portion 122 and the outer surface of the valley portion 123 (that is, the height of the mountain portion 122) and the width in the longitudinal direction of the outer surface of the mountain portion 122 and the outer surface of the valley portion 123 can be arbitrarily determined. The protective tube of the present invention is not limited to the shape and size of the corrugated tube of this embodiment.

  Further, a guide portion (accommodating groove 124) is formed on the outer surface of the tube wall 121. In the present embodiment, the guide portion extends linearly along the longitudinal direction of the protective tube 120 and extends over the entire longitudinal direction of the outer surface of the protective tube 120. The guide part is formed of a receiving groove 124 having a predetermined width that is recessed in the outer surface of the protective tube 120 without penetrating the tube wall 121 inward and outward, and that accommodates the messenger wire 110 without being displaced in the circumferential direction of the protective tube 120. More specifically, a semi-circular cutout 124a is formed in the peak portion 122 that is continuous in the longitudinal direction so that a part of the circumferential direction is recessed, and a plurality of continuous portions in the longitudinal direction (straight) are formed. An accommodation groove 124 is defined by the notch 124a. That is, the guide part is formed in a nested shape as a semicircular arc-shaped concave curved surface without protruding from the outer surface of the protective tube 120. The opening (or diameter) of the semicircular accommodation groove 124 is preferably formed to be the same as or slightly larger than the diameter of the messenger wire 110. Further, the depth of the accommodation groove 124 is preferably smaller than the height of the peak portion 122. Thereby, a dent is not formed in the inner surface side of the trough part 123, and the volume of the protective tube 120 does not decrease. In addition, the depth of the accommodation groove 124 is preferably set smaller than the diameter of the messenger wire 110 so that the accommodated messenger wire 110 protrudes from the outer surface of the mountain portion 121. This is because, as will be described later, the band body 130 can come into contact with the outer surface of the mountain portion 122 and the outer surface of the messenger wire 110 when integrally coupled.

  The band body 130 is a band-shaped body having a predetermined width having a length that can surround both the messenger wire 110 and the protective tube 120. In the present embodiment, the band body 130 is made of a thin metal piece, and is excellent in strength, durability, weather resistance, etc. when used outdoors. As shown in FIGS. 1 and 6, the band body 130 includes a band-shaped band portion 131 and a fastening portion 132 that fastens both ends of the band portion 131. The band portion 131 has appropriate elasticity or plasticity, and can be deformed along the outer surfaces of the protective tube 120 and the messenger wire 110 by being tightly wound around the outer surface. In the present embodiment, a plurality of band bodies 130 are used so as to be installed at predetermined intervals according to the length of the protective tube 120. The band body of the present invention is not limited to the configuration of the embodiment, and can be arbitrarily selected. For example, the band body may be a binding band provided with a lock mechanism.

  As described above, the messenger wire 110, the protective tube 120, and the band body 130 are separate bodies and are manufactured independently.

  Based on the above description, the configuration of the protective tube hanging device 100 will be described in more detail. In the present embodiment, the protective tube suspending device 100 is installed at a high position with respect to the utility pole and suspends wiring and piping materials in the air. Therefore, both ends of the messenger wire 110 are utility poles (not shown). ), Etc., and is installed in the air. The messenger wire 110 is preferably tensioned. However, the messenger wire 110 may be installed in a relaxed state to some extent.

  In the protective tube suspension device 100 of the present embodiment, the wiring / pipe material (not shown) is accommodated and protected so as to be disposed while being supported by the stretched messenger wire 110. The tube 120 is attached to the messenger wire 110 along the longitudinal direction thereof. At this time, the messenger wire 110 is housed in the housing groove 124 that is a guide portion provided in the protective tube 120. As shown in FIG. 3, the accommodation groove 124 has a substantially semicircular shape in cross section, and about half of the cross section of the messenger wire 110 is disposed in the accommodation groove 124. And the messenger wire 110 and the protective tube 120 are extended in the elongate direction in the state mutually contact | abutted via the guide part (accommodating groove 124). That is, the protective tube 120 is linearly guided and regulated with respect to the messenger wire 110 by the guide portion. As shown in FIGS. 3A and 3B, the messenger wires 110 are located close to each other so that a part of the messenger wire 110 is recessed into the tube wall 121 of the protective tube 120. Thereby, after arrange | positioning outdoors, it can suppress that the protective tube 120 rocks | fluctuates with respect to the messenger wire 110 under the influence of a wind pressure. Further, according to FIG. 3B, since the depth of the accommodation groove 124 is smaller than the height of the peak portion 122, there is a gap between the outer surface of the valley portion 123 and the outer surface of the messenger wire 110 in the attached state.

  The messenger wire 110 and the protective tube 120 in a state of being attached to each other are wound and secured in the circumferential direction by an annular band body 130. The band part 131 completely surrounds the outer periphery of the messenger wire 110 and the protective tube 120, and is firmly fastened by the fastening part 132. As shown in FIG. 3A, the band body 130 is elastically or plastically deformed along both outer surfaces so that the inner surface of the band portion 131 abuts both the outer surface of the peak portion 122 of the protective tube 120 and the outer surface of the messenger wire 110. doing. In other words, the outer surface of the messenger wire 110 protrudes radially outward from the receiving groove 124, and the diameter of the messenger wire 110 is set so that the band body 130 can contact both the outer surface of the protective tube 120 and the outer surface of the messenger wire 110. On the other hand, the depth and shape of the receiving groove 124 as a guide portion are set. Accordingly, the messenger wire 110 and the protective tube 120 are firmly coupled in a state where the messenger wire 110 is partially accommodated in the accommodating groove 124 without being displaced in the circumferential direction of the protective tube 120. Furthermore, the band body 130 binds the messenger wire 110 and the protective tube 120 so as to crush the covering portion 112 made of a soft synthetic resin that covers the shaft portion 111 of the messenger wire 110. That is, the covering portion 112 is crushed at the position where the band body 130 is wound, and a part in the longitudinal direction of the messenger wire 110 is deformed radially inward. Due to the step between the deformed portion and the non-deformed portion, the band body 130 can be effectively prevented from shifting in the longitudinal direction of the protective tube 120 and the messenger wire 110.

  In FIG. 1, only one band body 130 is depicted, but a plurality of band bodies 130 can be installed at arbitrary positions along the longitudinal direction. And it becomes easy to isolate | separate a part of protective tube 120 from the stretched messenger wire 110 by selecting the coupling | bonding position by the band body 130 suitably. For example, as shown in FIG. 5, the protective tube 120 on the center side is coupled to the messenger wire 110 by two band bodies 130 at a predetermined interval, and both ends of the protective tube 120 are free ends. Then, the protective tube 120 can be freely disposed away from the messenger wire 110 by bending the protective tube 120 so as to be detached from the receiving groove 124 of the guide portion. Note that the relative length relationship between the messenger wire 110 and the protective tube 120 is arbitrarily determined. That is, the lengths of the messenger wire 110 and the protective tube 120 may be the same, or one of the messenger wire 110 and the protective tube 120 may be longer than the other. When the protective tube 120 is longer than the messenger wire 110, it is preferable that the protective tube 120 be bent as shown in FIG. Furthermore, although not shown in the drawings, by attaching a bent protective tube 130 to another stretched messenger wire 110, the protective tube 130 can be refracted in the air and piped.

  Next, with reference to FIG. 6, a method of installing the protective tube suspending apparatus 100 and suspending a flexible synthetic resin protective tube 120 will be described. First, a messenger wire 110, a protective tube 120, and one or a plurality of band bodies 130, which are separately manufactured, are prepared. Both ends of the messenger wire 110 are fixed to a structure such as a utility pole, and are installed in the air in a tension state. Then, as shown in FIG. 6, the protection tube 120 is attached to the messenger wire 110 along the longitudinal direction so that the messenger wire 110 is accommodated in the accommodation groove 124 of the guide portion of the protection tube 120. The messenger wire 110 is received in the receiving groove 124 so that the protective tube 120 is guided linearly, and the relative movement in the circumferential direction of the messenger wire 110 and the protective tube 120 is restricted. It is easy to maintain the attached state. Then, one or a plurality of bands are selected so that the protective tube 120 and the messenger wire 110 are bundled in a state where one or a plurality of coupling sites in the longitudinal direction are selected and the protective tube 120 is attached to the messenger wire 110 by the guide portion. The body 130 is wound at an interval in the longitudinal direction of the messenger wire 110, and the protective tube 120 is integrally secured to the messenger wire 110. More specifically, the band 131 surrounds the messenger wire 110 and the protective tube 120, the band 131 is tightened until the covering portion 112 of the messenger wire 110 is crushed, and both ends of the band 131 are locked by the fastening portion 132. . In this way, the protective tube 120 is integrally supported by being suspended in the air by the messenger wire 110, and wiring and piping materials can be disposed in the air.

  The method described here is merely an example, and a person skilled in the art can change the order of the steps, or can omit or change unnecessary steps depending on the situation. For example, after the protective tube 120 is secured to the messenger wire 110 in advance, the messenger wire 110 may be stretched over a structure, and the protective tube may be suspended and supported in the air. That is, the contractor stretches the protective tube 120 and the messenger wire 110 in a state of being integrated with the band body 130 in advance (that is, assembling integrally at the time of manufacture and shipment), and the messenger wire 110 stretched in advance. Both processes of assembling the protective tube 120 with the band body 130 (that is, assembling in the field) can be selected. Further, the wiring / piping material may be accommodated in the protective tube 120 in advance, or may be inserted into the protective tube 120 after the protective tube hanging device 100 is installed.

  Hereinafter, the effect of the protection tube suspension apparatus 100 of one Embodiment which concerns on this invention is demonstrated.

  According to the protection tube suspension device 100 of the present embodiment, the messenger wire 110 is accommodated without being displaced in the circumferential direction of the protection tube 120 by providing the guide portion that is the accommodation groove 124 on the outer surface of the protection tube 120. The attachment of the protective tube 120 to the messenger wire 110 is guided. Thereby, both can be easily transferred to a state where they are attached to each other, and it is easy to maintain the attached state. Furthermore, in a state where the protective tube 120 is attached to the messenger wire 110, the messenger wire 110 and the protective tube 120 can be integrally coupled by the band body 130 as a coupling means. That is, it is possible to manufacture the protection tube 120 and the messenger wire 110 as separate bodies and to easily assemble them together with the band body 130. Therefore, the protection tube suspending device 100 of the present embodiment can be easily integrated by attaching the protection tube 120 and the messenger wire 110 manufactured separately. Therefore, the manufacturing process is simplified as compared with a conventional (Patent Document 1) integrally formed apparatus.

  Further, according to the protection tube suspending device 100 of the present embodiment, the band body 130 selects a portion where the long messenger wire 110 and the protection tube 120 need to be coupled, and the messenger wire 110 is protected by the protection tube. 120 can be assembled together. Further, by using the band body 130, the protection tube 120 and the messenger wire 130 are stretched in a state of being integrated with the band body 130 in advance, and the protection tube 120 is attached to the pre-stretched messenger wire 110. Both steps of assembling at 130 are selectable. Then, by appropriately selecting the coupling position by the band body 130, it becomes easy to separate a part of the protective tube 130 from the stretched messenger wire 110, and the piping path can be freely selected.

  Further, in the conventional (Patent Document 1) self-supporting tube (A), the corrugated pipe (10) and the messenger wire (11) are coupled via the neck portion of the jacket (12). Since the corrugated pipe (10) is suspended from the messenger wire (11) via the neck, it is a problem that the corrugated pipe (10) swings greatly under the influence of wind and rain when placed outdoors. On the other hand, according to the protection tube suspension device 100 of the present embodiment, the guide portion is nested in the outer surface of the protection tube 120 so that a part of the messenger wire 110 is the tube wall of the protection tube 120. It is arranged so as to be embedded in 121. Thus, since both are close enough at the time of installation, after arrange | positioning outdoors, it is suppressed that the protective tube 120 rocks | fluctuates with respect to the messenger wire 110 under the influence of a wind pressure.

[Second Embodiment]
With reference to FIG. 7 thru | or FIG. 10, the protection tube suspension apparatus 200 of 2nd Embodiment which is one Embodiment of this invention is demonstrated. In the present embodiment, components having the same last two digits in the components indicated by three digits have the same or similar features unless otherwise described, and a part of the description is omitted.

  As shown in FIGS. 7 and 8, the protective tube suspending device 200 is supported by a messenger wire 210 installed in the longitudinal direction, and the messenger wire 210, and wiring / piping material (not shown) is arranged inside. The protective tube 220 is provided, and a band body 230 as a coupling means for integrally coupling the protective tube 220 and the messenger wire 210 along the longitudinal direction. The protective tube 220 is linearly attached to the messenger wire 210 by a guide portion (accommodating groove 224) formed in the protective tube 220. The messenger wire 210 and the band body 230 of the second embodiment are the same as the messenger wire 110 and the band body 130 of the first embodiment, and the configuration of the guide portion 223 of the protective tube 220 is the same as that of the first embodiment. Is different.

  The protective tube 220 is a corrugated tube made of flexible synthetic resin that extends in the longitudinal direction. That is, the protective tube 220 has flexibility that can be wound or bent. FIG. 10 is a perspective view of the protective tube 220. As shown in FIG. 10, the protective tube 220 has a tube wall 221 having a predetermined thickness, and crest portions 222 and trough portions 223 are alternately continuous in the longitudinal direction on the tube wall 221. A guide portion is formed on the outer surface of the tube wall 221. In the present embodiment, the guide portion extends linearly along the longitudinal direction of the protective tube 220 and is formed on a part of the outer surface of the protective tube 220 in the circumferential direction. As shown in FIG. 9, the guide portion has an accommodation groove 224 having a predetermined width that accommodates the messenger wire 210 without shifting in the circumferential direction of the protective tube 220 without penetrating the tube wall 221 in and out. The housing groove 224 is defined between a pair of protrusions 224a that protrude from a part of the circumferential direction of each peak portion 222 that is continuous in the longitudinal direction. More specifically, a semicircular concave surface is formed between the protrusions 224a, and a part of the outer surface of the messenger wire 210 is accommodated therein. That is, the guide part of the present embodiment is formed at a position protruding from the outer surface of the protective tube 220. The depth of the accommodating groove 224 (the height of the protrusion 224a) is preferably set smaller than the diameter of the messenger wire 210 so that the accommodated messenger wire 210 protrudes from the outer surface of the peak portion 221.

  In the protection tube suspension device 200 of the present embodiment, the protection tube 220 is provided with the messenger so that the wiring / piping material (not shown) is accommodated and protected inside while being supported by the messenger wire 210. Attached to the wire 210 along the longitudinal direction thereof. At this time, the messenger wire 210 is housed in the housing groove 224 between the protrusions 224 a that project from the protective tube 220. As shown in FIG. 9, the housing groove 224 has a substantially semicircular shape in cross section, and about half of the cross section of the messenger wire 210 is disposed in the housing groove 224. That is, the guide wire guides the attachment of the messenger wire 210 and the protective tube 220, so that the messenger wire 210 and the protective tube 220 are in contact with each other via the guide portion (accommodating groove 224) in the longitudinal direction. It extends. As shown in FIGS. 9A and 9B, since the outer surface of the messenger wire 210 is positioned so as to contact the outer surface of the tube wall 221 of the protective tube 220, both are relatively close to each other. Thereby, after arrange | positioning outdoors, it is restrained relatively that the protective tube 220 rock | fluctuates with respect to the messenger wire 210 under the influence of a wind pressure. Further, according to FIG. 9B, the outer surface of the messenger wire 210 abuts the outer surface of the peak portion 222 in the attached state, and the outer surface of the valley portion 223 and the outer surface of the messenger wire 210 are separated by the height of the peak portion 221. Yes.

  In the protective tube suspending device 200, the messenger wire 210 and the protective tube 220, which are attached to each other, are wound and secured in the circumferential direction by an annular band body 230. The band portion 231 completely surrounds the outer periphery of the messenger wire 210 and the protective tube 220 and is fastened by the fastening portion 232. As shown in FIG. 9A, the band body 230 is deformed along both outer surfaces so that the inner surface of the band portion 231 contacts both the outer surface of the peak portion 222 of the protective tube 220 and the outer surface of the messenger wire 210. Accordingly, the messenger wire 210 and the protective tube 220 are firmly coupled in a state where the messenger wire 210 is accommodated in the accommodating groove 224 without being displaced in the circumferential direction of the protective tube 220. Furthermore, the band body 230 binds the messenger wire 210 and the protective tube 220 so as to crush the covering portion 212 made of a soft synthetic resin that covers the shaft portion 211 of the messenger wire 210. This effectively suppresses the band body 230 from shifting in the longitudinal direction of the protective tube 220 and the messenger wire 210.

  The method for installing the protective tube suspending apparatus 200 is substantially the same as that in the first embodiment, and thus the description thereof is omitted.

  Therefore, the protection tube hanging device 200 of the present embodiment is simply provided with a protection tube 220 and a messenger wire 210 that are manufactured separately, similarly to the protection tube hanging device 100 of the first embodiment. Both can be easily integrated.

[Third Embodiment]
With reference to FIG. 11 thru | or FIG. 14, the protection tube suspension apparatus 300 of 3rd Embodiment which is one Embodiment of this invention is demonstrated. In the present embodiment, components having the same last two digits in the components indicated by three digits have the same or similar features unless otherwise described, and a part of the description is omitted.

  As shown in FIGS. 11 and 12, the protective tube suspension device 300 is supported by a messenger wire 310 installed in the longitudinal direction and the messenger wire 310, and wiring / piping material (not shown) is arranged inside. The protective tube 320 is provided, and a coupling means (bonding portion 330) for integrally coupling the protective tube 320 and the messenger wire 310 along the longitudinal direction. The protective tube 320 is linearly attached to the messenger wire 310 by a guide portion (accommodating groove 324) formed in the protective tube 320. The messenger wire 310 and the protective tube 320 of the third embodiment are the same as the messenger wire 110 and the protective tube 120 of the first embodiment, and the band body 130 as in the first embodiment is adopted as the coupling means. Absent.

  In the present embodiment, the coupling means is configured to integrally bond the covering portion 312 and the outer surface of the protective tube 320 in a state where the messenger wire 310 is attached to the protective tube 320 by the guide portion. “Adhesion” by the coupling means is adhesion by an adhesive, and as the coupling means, for example, any adhesive such as vinyl chloride resin type, acrylic resin type, epoxy resin type or the like can be adopted. Further, the “adhesion” by the coupling means may be adhesion by thermal fusion.

  As shown in FIG. 11, in the protection tube suspension device 300 of the present embodiment, a wiring / piping material (not shown) is accommodated and protected inside while being supported by the messenger wire 310. In addition, the protective tube 320 is attached to the messenger wire 310 along the longitudinal direction thereof. At this time, the messenger wire 310 is accommodated in the accommodation groove 324 of the guide portion that is recessed in the protective tube 320. As shown in FIG. 13, the housing groove 324 has a substantially semicircular shape in cross section, and about half of the cross section of the messenger wire 310 is disposed in the housing groove 324. That is, the guide wire guides the attachment of the messenger wire 310 and the protective tube 320, so that the messenger wire 310 and the protective tube 320 extend in the longitudinal direction in contact with each other via the guide portion. As shown in FIGS. 13A and 13B, a part of the messenger wire 310 is positioned so as to be embedded in the tube wall 321 of the protective tube 320, so that they are sufficiently close to each other. . Thereby, after arrange | positioning outdoors, it is suppressed that the protection tube 320 rocks | fluctuates with respect to the messenger wire 310 under the influence of a wind pressure.

  The messenger wire 310 and the protective tube 320 that are attached to each other are joined together by an adhesive portion 330 by a joining means. The bonding portion 330 is formed on the concave curved surface of the housing groove 324 of the protective tube 320 and extends over the entire length of the protective tube 320. The outer surface of the synthetic resin protective tube 320 and the outer surface of the synthetic resin covering portion 312 of the messenger wire 310 are bonded to each other in the entire longitudinal direction. More specifically, as shown in FIG. 13B, the messenger wire 310 is bonded to the outer surface of the peak portion 322 so as to form a gap between the outer surface of the valley portion 323 and the covering portion 312. That is, the messenger wire 310 is bonded to the outer surface of the peak portion 322 of the corrugated tube 320, thereby forming a gap between the outer surface of the valley portion 323 and the covering portion 312. As a result, the protective tube 320 or the messenger wire 310 is formed. Compared with a single unit, a decrease in the flexibility of the entire protective tube suspension device 300 is suppressed. Therefore, in the protective tube hanging device 300 of the present embodiment, the messenger wire 310 is accommodated in the accommodating groove 324 without being displaced in the circumferential direction of the protective tube 320, while suppressing a decrease in flexibility as a whole. The messenger wire 310 and the protective tube 320 are firmly coupled.

  Further, in the protective tube hanging device 300, the messenger wire 310 is formed on the covering portion 312 so that the covering portion 312 can be cut to form an outlet 313 for pulling out the steel shaft portion 311 from the covering portion 312. A part in the circumferential direction is bonded to the outer surface of the protective tube 320. That is, when the protective tube 320 is bent with respect to the messenger wire 320 stretched in a straight line, as shown in FIG. 14, the covering portion 322 is cut with a cutter or the like at a portion where the protective tube 320 is bent. The shaft portion 321 and the covering portion 322 can be partially separated. In this state, by moving the protective tube 320 in a direction away from the messenger wire 310, the protective tube 320 with the cut end of the covering portion 322 adhered can be bent in a desired direction. Therefore, even at the location where the protective tube 320 and the messenger wire 310 are bonded, the covering portion 312 and the shaft portion 311 are separated through the outlet 313 formed by tearing the covering portion 312, and as a result, from the messenger wire 310. A part of the protective tube 320 can be easily separated. Alternatively, in the present embodiment, the adhesive portion 330 is formed over the entire longitudinal direction, but the protective tube 320 may be bent and piped by not forming the adhesive portion 330 at a location where the protective tube 320 is bent and piped. Is possible.

  Next, a method of installing the protective tube suspending device 300 and suspending the flexible protective tube 320 made of synthetic resin will be described. First, a messenger wire 310, a protective tube 320, and a coupling means (adhesive) manufactured separately are prepared. Next, an adhesive is applied to the surface of the accommodation groove 324 that is a guide portion of the protection tube 320, and the messenger is placed along the longitudinal direction so that the messenger wire 310 is accommodated in the accommodation groove 324 of the protection tube 320. Attached to the wire 310. It is left for a predetermined time in the attached state until the bonding portion 330 is solidified and the both outer surfaces are bonded. At this time, since the messenger wire 310 is accommodated in the receiving groove 324 without being displaced in the circumferential direction, the transition to the attached state and the maintenance of the attached state are easy. Then, both ends of the messenger wire 310 to which the protective tube 320 is attached are fixed to a structure such as a utility pole, and are installed in the air in a tension state. In this way, the protective tube 320 is suspended and supported in the air by the messenger wire 310, and wiring and piping materials can be disposed in the air.

  The method described here is merely an example, and a person skilled in the art can change the order of the steps, or can omit or change unnecessary steps depending on the situation. For example, as described above, it is preferable in terms of construction stability that the messenger wire 310 and the protective tube 320 are bonded in advance to configure the protective tube hanging device 300 and then disposed in the air. Adhesion may be performed on site after being stretched over the structure.

  Therefore, the protective tube suspending device 300 of the present embodiment can be easily integrated by easily attaching the protective tube 320 and the messenger wire 310 manufactured separately.

[Fourth Embodiment]
With reference to FIG. 15 thru | or FIG. 17, the protection tube suspension apparatus 400 of 4th Embodiment which is one Embodiment of this invention is demonstrated. In the present embodiment, components having the same last two digits in the components indicated by three digits have the same or similar features unless otherwise described, and a part of the description is omitted.

  As shown in FIGS. 15 and 16, the protective tube suspension device 400 is supported by a messenger wire 410 installed in the longitudinal direction and the messenger wire 410, and wiring / piping material (not shown) is arranged inside. The protective tube 420 is provided, and a coupling means (bonding portion 430) for integrally coupling the protective tube 420 and the messenger wire 410 along the longitudinal direction. The protective tube 420 is linearly attached to the messenger wire 410 by a guide portion (projection 424) formed in the protective tube 420. The messenger wire 410 and the coupling means (adhesive portion 430) of the fourth embodiment are the same as the messenger wire 310 and the adhesive portion 330 of the third embodiment, but the shape of the protective tube 420 is different.

  The protective tube 420 is a corrugated tube made of a flexible synthetic resin that extends in the longitudinal direction. That is, the protective tube 420 has flexibility that can be wound or bent. The protective tube 420 has a tube wall 421 having a predetermined thickness, and crest portions 422 and trough portions 423 are alternately continued in the longitudinal direction on the tube wall 421. Further, a guide portion (protrusion 424) is formed on the outer surface of the tube wall 421. In the present embodiment, the guide portion extends linearly along the longitudinal direction of the protective tube 420 and is formed on a part of the outer surface of the protective tube 420 in the longitudinal direction. As shown in FIG. 15, the guide portion is a row of protrusions 424 formed in the longitudinal direction. Although not shown, a plurality of protrusions 424 are intermittently formed in a straight line along the longitudinal direction. As shown in FIG. 16, a protrusion 424a is formed so as to protrude radially outward from an outer surface of a mountain portion 422 continuous in the longitudinal direction. A plurality of continuous protrusions 424a cooperate to form a protrusion 424a extending in the longitudinal direction. The height of the ridge 424 is preferably larger than the diameter of the messenger wire 410 so that the messenger wire 410 can stably contact the ridge 424.

  As shown in FIG. 15, the protection tube suspension device 400 of the present embodiment accommodates and protects a wiring / piping material (not shown) while being supported by a messenger wire 410. In addition, a protective tube 420 is attached to the messenger wire 410 along its longitudinal direction. At this time, the messenger wire 410 is disposed so as to abut on a plurality of protrusions 424 as guide portions protruding from the protective tube 420. That is, the guide portion (protrusion 424) guides the attachment of the messenger wire 410 and the protective tube 420, so that the messenger wire 410 and the protective tube 420 are in contact with each other via the guide portion in the longitudinal direction. It extends. Then, the messenger wire 410 and the protective tube 420 that are attached to each other are joined together by an adhesive portion 430 by a joining means. The bonding portion 430 is formed on both the side surface of the protrusion 424 and the outer surface of the peak portion 422. However, the bonding portion 430 may be formed on either the side surface of the protrusion 424 or the outer surface of the peak portion 422.

  As shown in FIGS. 17A and 17B, since the outer surface of the messenger wire 410 is positioned so as to contact the outer surface of the tube wall 421 of the protective tube 420, both are relatively close to each other. Thereby, after arrange | positioning outdoors, it is restrained relatively that the protective tube 420 rocks | fluctuates with respect to the messenger wire 410 under the influence of a wind pressure. Furthermore, according to FIG. 17B, the messenger wire 410 is bonded to the outer surface of the peak portion 422 so as to form a gap between the outer surface of the valley portion 423 and the covering portion 412. That is, the messenger wire 410 is bonded to the outer surface of the peak portion 422 of the corrugated tube 420, thereby forming a gap between the outer surface of the valley portion 423 and the covering portion 412. As a result, the protective tube 420 or the messenger wire 410 is formed. Compared to a single unit, a decrease in flexibility of the entire protection tube suspension device 400 is suppressed. Therefore, in the protection tube hanging device 400 of the present embodiment, the messenger wire 410 is accommodated in the guide portion without being displaced in the circumferential direction of the protection tube 420, and the messenger is suppressed while suppressing a decrease in flexibility as a whole. The wire 410 and the protective tube 420 are firmly coupled.

  In the protection tube hanging device 400 of the present embodiment, the messenger wire 410 cuts the covering portion 412 and removes the steel shaft portion 411 from the covering portion 412 in the same manner as the protection tube hanging device 300 of the third embodiment. A part of the covering portion 412 in the circumferential direction is bonded to the outer surface of the protective tube 420 so that the outlet 413 for pulling out can be formed. That is, even at the place where the protective tube 420 and the messenger wire 410 are bonded, the covering portion 412 and the shaft portion 411 are separated through the outlet 413 formed by tearing the covering portion 412, and as a result, from the messenger wire 410. A part of the protective tube 420 can be easily separated. Alternatively, the protective tube 420 can be bent by not forming the bonding portion 430 at the portion where the protective tube 420 is bent.

  Next, a method for installing the protective tube suspending device 400 and suspending the flexible protective tube 420 made of synthetic resin will be described. First, the messenger wire 410, the protective tube 420, and the coupling means (adhesive) manufactured separately are prepared. Next, an adhesive is applied to the side surface of the ridge 42 of the protective tube 420 and / or the outer surface of the ridge 422 adjacent to the ridge 424, and the messenger wire 410 is routed to one or more side surfaces of the ridge 424 of the protective tube 420. As described above, the protective tube 420 is attached to the messenger wire 410 along the longitudinal direction. It is left for a predetermined time in the attached state until the bonding portion 430 is solidified and the both outer surfaces are bonded. At this time, since the protrusion 424 restricts relative movement of the messenger wire 410 and the protective tube 420 in one circumferential direction, it is relatively easy to shift to the attached state and maintain the attached state. Then, both ends of the messenger wire 410 to which the protective tube 420 is attached are fixed to a structure such as a utility pole, and are installed in the air in a tension state. Thus, the protective tube 420 is suspended and supported in the air by the messenger wire 410, and wiring and piping materials can be arranged in the air. Note that the protective tube 420 may be bonded to the messenger wire 410 stretched in advance and supported by being suspended in the air.

  Therefore, the protective tube hanging device 400 of the present embodiment can be easily integrated by attaching the protective tube 420 and the messenger wire 410 manufactured separately.

In addition, the method of 3rd and 4th embodiment of this invention can also be expressed as follows.

[Modification]
The present invention is not limited to the above embodiment, and various modifications can be made. Hereinafter, modifications of the present invention will be described. Note that, in each modification, components having the same last two digits in the components indicated by three digits have the same or similar characteristics unless otherwise specified, and a part of the description is omitted.

(1) The guide portion of the protective tube of the present invention can be deformed into various shapes as exemplified below, as long as it can guide the attachment of the protective tube and the messenger wire.

  FIG. 18 shows a protective tube 520 according to a modification of the present invention. The protective tube 520 includes a tube wall 521 having a predetermined thickness in which peak portions 522 and valley portions 523 are alternately continuous in the longitudinal direction, and a guide portion (accommodating groove 524) formed on the outer surface of the tube wall 521. In the guide portion, a first protrusion 524a projects radially outward from the outer surface of the peak portion 522. And in the peak part 522 adjacent to this, the 2nd protrusion 524b has projected from the peak part 522 outer surface in the radial direction in the position shifted | deviated from the 1st protrusion 524a by the predetermined distance in the circumferential direction. Since the first protrusions 524a and the second protrusions 524b are alternately continuous, the first protrusions 524a and the second protrusions 524b in the circumferential direction are linearly arranged in the longitudinal direction for accommodating the messenger wire. An extending receiving groove (or receiving path) 524 is defined. That is, the pair of first and second protrusions 524a and 524b may not be in the same peak portion 522. By accommodating the messenger wire in the accommodation groove 524, the protective tube 520 is guided linearly, and the relative movement in the circumferential direction of the messenger wire and the protective tube 520 is restricted, so that the protective tube 520 and the messenger wire Coupling (attachment) is guided. In a state where the protective tube 520 is attached to the messenger wire via the guide portion, the two can be integrally coupled by a band body or a coupling means by adhesion.

  FIG. 19 shows a protective tube 620 according to a modification of the present invention. The protective tube 620 includes a tube wall 621 having a predetermined thickness in which peak portions 622 and valley portions 623 are alternately continuous in the longitudinal direction, and a guide portion (planar path 624) formed on the outer surface of the tube wall 621. In the guide portion, a rectangular body 624a having a planar outer surface is projected from the outer surface of each mountain portion 622 continuous in the longitudinal direction. Then, the plurality of rectangular bodies 624a are aligned on the straight line along the longitudinal direction, so that a planar path 624 extending linearly in the longitudinal direction is defined as a guide portion. By connecting the messenger wire to the planar path 624, the coupling (attachment) of the protective tube 620 and the messenger wire is guided. In a state where the protective tube 620 is attached to the messenger wire by the guide portion, the two can be integrally coupled by a band body or a coupling means by adhesion. Note that, unlike the other embodiments, the guide portion of the present modification functions not only to restrict the relative movement of the messenger wire and the protective tube in the circumferential direction, but mainly to guide (position) the attachment position.

  FIG. 20 shows the protective tube 720 of the present invention. The protective tube 720 includes a tube wall 721 having a predetermined thickness in which peak portions 722 and valley portions 723 are alternately continuous in the longitudinal direction, and a guide portion (planar path 724) formed on the outer surface of the tube wall 721. In the guide portion, the outer surface of each peak portion 722 continuous in the longitudinal direction is cut out to form a rectangular surface 724a. Then, the plurality of rectangular surfaces 724a are aligned on the straight line along the longitudinal direction, whereby a planar path 724 extending linearly in the longitudinal direction is defined as a guide portion. Similar to the protective tube 620, the messenger wire is routed to the planar path 724, so that the connection (attachment) of the protective tube 720 and the messenger wire is guided. In a state where the protective tube 720 is attached to the messenger wire by the guide portion, the two can be integrally coupled by a band body or a coupling means by adhesion. In addition, the guide part of this modification does not restrict | limit the relative movement of the circumferential direction of a messenger wire and a protective tube like the protective tube 620, but functions so that the attachment position may mainly be guided (positioning). .

  Although not shown, the guide portion may be a mark or a stamp in addition to the concave portion, step portion, groove portion, and flat portion as described above, and guides and regulates the protective tube linearly along the messenger wire. It is sufficient that at least one of the above is made.

(2) In the above embodiment, the protective tube is a corrugated tube, but the present invention is not limited to this.
