[Detailed description of the device] [Industrial applications]

The protector for a strut according to the present invention relates to protection used by being attached to a structure, mainly a strut supporting a utility pole.

[Prior art]

The poles are set up diagonally from above the ground to near the top of the poles to support the poles erected on the roadside. Sexual plants gradually wrap around upwards. In this way, when the ivy plant wraps around the upper part of the utility pole along the support line, snakes and lizards rise along the ivy plant and touch the wire to cause a short circuit, which causes a power failure. Was there. In order to prevent such problems, a bowl-shaped tufting tool or a tubular tufting protector was attached in the middle of the rope to prevent the ivy plant from winding up, for example 52
As shown in Japanese Patent Publication No. 56436, a cylinder and an auxiliary cylinder supported inside by a supporting tool are provided inside the cylinder, and further the structure is such that the cylinder is divided in half and is connected to the struts with a connecting tool inside. Shunko 47-3419, which was designed to prevent plants from winding up
The one shown in Japanese Patent Publication No. 6 is known.

[Problems to be solved by the device]

Although the bowl-shaped vine turning tool can temporarily prevent winding of the ivy plant around the chords, when the vine plant grows, the bowl-shaped vine turning tool is thin. There is a problem that the ivy plant easily gets over this device and eventually winds around the rope above the device and climbs to near the upper part of the utility pole. Also, most of the above-mentioned tubular support cord protectors are formed by bending a synthetic resin plate having a small thickness and a short width into a cylindrical shape, and support a disc-shaped lid plate fitted at both ends of the cylinder. Although it is designed to fix the tubular strut protector by fixing it to the rope, it is troublesome to fix the cylinder over both lid plates in addition to the work of fixing the disk-shaped lid plate to the strut. However, there is a problem that it is troublesome and the work efficiency is poor. In addition, because the tubular support cord protector attached to the support cord in this way has insufficient diameter and length, the ivy plant that has climbed around the lower end of the support cord grows. Then, there is also a problem in that the rope further climbs while winding around the outer circumference of the support cord protector. In addition, the cylindrical strut protector attached to the strut is easily deformed due to changes in the surrounding environment such as temperature differences during the four seasons, and the joint portion of the cylinder opens its mouth. There is also a problem that plants may enter the inside of the cylinder, or ivy plants that have entered the inside may come out from here and climb up further easily. Further, as shown in Japanese Utility Model Laid-Open No. 52-56436, in the case where a cylinder and an auxiliary cylinder supported by a supporting tool are provided inside thereof,
Not only the work of fixing the auxiliary cylinder in the cylinder through the support is required, but also because the lower end of the cylinder is open, ivy plants enter from this open part and light enters There is a problem that the ivy plant grows in this cylinder, and the ivy plant climbs the strut through the gap above. In addition, as shown in Japanese Utility Model Publication No. 47-34196, the cylinder is halved, and the side edges of the partial cylinders are butted against the tips of the support fixtures fixed in a state orthogonal to the stanchions. In the case of fixing, since the partial cylinder is formed in the shape of a single plate, this partial cylinder easily deforms easily due to thermal strain such as solar heat or low temperature of snow, and the side edge joint part There was a problem that the mouth opened and the light-shielding property was impaired, so that the ivy plant grew in the cylinder and the ivy plant climbed up the cord. In particular, in the structures shown in these publications, since the upper and lower ends are open, the ivy plant climbs up directly on the inward rope without passing through the outer circumference of the cylinder. There is. The present invention has been proposed in view of the above problems, and can be easily attached to a rope, can reliably prevent vines from being wrapped, and has a durable rope protector. The purpose is to be able to provide.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, a supporter for a rope according to the present invention is a protector for a rope that extends from the ground and is attached to a middle portion of the rope that supports a structure, and is an opaque synthetic resin having a light-shielding property. The protector body is formed of a hollow double-walled structure and is a cylindrical divided body divided in half in the longitudinal direction, and the divided bodies are connected at one end by a thin hinge part. , The inner surface of the split body is configured to hold the strut, and when the free ends of the split body are fixed in a tubular shape by the connecting means, both ends of the cylindrical shape become the light-shielding strut. It is characterized in that it is configured to abut.

[Action]

In the device for protecting a strut according to the present invention, since the divided bodies are connected at their ends by thin hinge portions, the inner surfaces of the divided bodies are made into a cylindrical shape with the hinge portions as the center of rotation, Transport it to the desired location. The protector of the strut thus conveyed is once opened by opening the split body so that the strut penetrates through the central portion thereof, and the split body is connected by the connecting means by aligning the inner surfaces of the split body with the hinge portion as the center of rotation. Then, when it is fixed again in a cylindrical shape, the protector for the axon is connected to the middle part of the axon. In this way, the protector for the strut attached to the middle of the strut is
The ivy plant that has climbed up to the vicinity of its lower end while wrapping around the rope further grows when it is wrapped, but the outer diameter and length of the cylinder are such that the ivy plant does not wind. Since it will slip off by its own weight by one lap from, the wrapping of the ivy plant is reliably prevented. Further, in the device for protecting a strut according to the present invention, since the divided bodies are integrally formed in a state of being hollow, even if the outer wall portion is distorted by the heat of the surroundings or the like, the inner wall portion is not surely distorted. Therefore, the joint surface portion of the divided body is prevented from being deformed due to thermal strain or the like.

【Example】

Hereinafter, an embodiment of a protector for a rope according to the present invention will be described with reference to the drawings. FIG. 1 shows an exploded perspective view of a supporter for an axon, and reference numeral 1 generally indicates a protector for an axon. This strut protector 1 is a split body 2a, 2b in which a cylinder is divided into two.

As shown in FIG. 3, a hollow S is formed between the thin-walled cylindrical walls 4 and 5 by a double wall structure in which thin-walled cylindrical walls 4 and 5 are formed inside and outside, respectively. Here, the diameter φ of the protector 1 is about 18 cm or more and the length L is 50 cm.
It is formed as described above. Semicircular recesses 9 and 10 are formed in the central portions of the upper end 6 and the lower end 7 of each of the split bodies 2a and 2b, and semi-circular recesses 9 and 10 through which a supporting line 8 described later penetrates are formed. A fitting groove 12 into which a light-shielding seal 11 made of sponge is fitted is formed therein. The light-shielding seal 11 made of sponge is provided with a fitting hole 13 at the center thereof so as to be fitted on the outer peripheral surface of the support line 8. When the divided bodies 2a and 2b are assembled, the light shielding fitting means 16 and the divided bodies 2a and 2b are cylindrically formed on the upper surface 6, the lower end portion 7, and the left and right side edge portions 14 and 15 which face each other. A connecting means 17 for fixing the assembled state is provided. The light shielding fitting means 16 includes the upper end portion 6 of the one divided body 2a,
A linear fitting protrusion 18 is formed so as to project along the respective lower surfaces of the lower end portion 7 and the upper surfaces of the left and right side edge portions 14 and 15, and the upper end portion 6, the lower end portion 7, and the left and right portions of the other split body 2b are formed. Side edge of
Fitting groove 19 where the fitting projection 18 fits on the upper surface of each of 14 and 15
Are recessed. In addition, a fitting fixing portion 21 that encloses a fitting 20 fixed to the support line 8 is formed at the upper end of the inner cylindrical wall 4 of each of the divided bodies 2a and 2b. As shown in FIG. 3, it is formed of a box-shaped metal fitting 23 of a two-divided type fixed to a support line by a bolt 22. The connecting means 17 is formed by a fastener 24 having arrow-shaped ends formed at both ends and a fitting hole 25 into which the arrow-shaped portion of the fastener 24 is inserted and fixed. The supporting line 8 is formed by twisting relatively thick wires together, and as shown in FIG. 4, a peg 28 embedded in the upper part of the utility pole (construction) 26 planted at the roadside and underground 27. It is stretched over between. Incidentally, reference numeral 30 in the figure is a support portion of the stanchion 8 formed in the inner center of each of the divided bodies 2a and 2b. A case will be described in which the protector 1 is attached to the support line 8 stretched between the utility pole 26 and the peg 28 buried in the ground 27 as described above. First, the fixture 23 is securely fixed with the bolts 22 at the position of the supporting line 8 to which the protector 1 is to be attached. Next, as shown in FIG. 1, the split bodies 2a and 2b are opened to the left and right, and the fastener 24 is inserted into the fitting hole 25 of one of the split bodies 2a.
And the upper end 6 and the lower end 7 of the split body 2a.
The light-shielding seal (11) is fitted into the fitting groove (12). Thereafter, the split bodies 2a and 2b are positioned over the fitting holes 13 of the light-shielding seal 12 fitted to the upper end portion 6 and the lower end portion 7 of the split rope 2 and the upper end portion of the split body 2a. After the fitting and fixing portion 21 of 6 is positioned so as to face the fixture 23, the other divided body 2b is folded back at the hinge portion 3 and the upper surfaces thereof are brought into contact with each other, so that the fastener 24 fits the other divided body 2b. The split fixtures 2a and 2b are cylindrically assembled by fitting in the dowel hole 25 to form the protector 1, and the fitting fixing portion formed inside the protector 1.
21 includes the fixture 23 fixed to the support line 8 and is fixed without shifting. In this manner, in the protector 1 attached to the strut 8, the ivy plant 29 that has climbed up to the vicinity of the lower end of the protector 1 is wrapped around the tubular outer peripheral surface of the protector 1. Although it grows further, this ivy plant 19 can generally grow vertically up to about 50 cm, but if it goes further or slightly obliquely, it will hang down by its own weight until it grows to about 50 cm. There is a habit. Therefore, when the diameter φ of the protective equipment 1 is set to 18 cm or more, the circumference becomes 18 × π≈56.548, which exceeds the limit of the ability of the ivy plant 29 to wind alone, and the length L is 50 cm or more. It is prevented from extending from the protective device 1 to the upper strut 8 without being wound around the formed protective device 1. Protective equipment 1 from the ability of the ivy plant to stand alone.
The diameter φ of is calculated as 50 ÷ π≈15.915, and the effect can be generated with a diameter φ of 16 cm or more. In the above-mentioned embodiment, the protector 1 is attached to the supporting line 8 for supporting the electric pole, but it is needless to say that the protective device 1 can be applied to not only such a supporting line but also a supporting line for supporting a structure such as a signboard. Needless to say, the number of divided bodies forming the protector 1 can be three or more. Further, in the above-mentioned embodiment, each divided body 2a, 2b is formed by the inner and outer cylindrical walls 4,
Although the space 5 is hollow S, it is also possible to fill the hollow portion with styrofoam or the like. Further, in the above-mentioned embodiment, the divided bodies 2a and 2b are connected by the hinge 3 and integrally molded by blow molding, but they may be formed independently or the inner and outer cylinders of the divided bodies 2a and 2b. It goes without saying that the walls 4 and 5 can be formed as separate parts and then assembled to form the divided bodies 2a and 2b. In addition, the joint surface of each divided body 2a, 2b is an adhesive (connecting means)
Or tape on the periphery of the joint surface (connecting means)
The fastener 24 and the light-shielding fitting means 14 can be omitted by attaching. If the protective tool 1 is fixed directly to the struts 8 by filling with an adhesive, caulking agent or the like instead of the light-shielding seal 12 of the above-mentioned embodiment, the fixture 23 and the fitting fixing portion 21 containing the fixture 23 are provided. It can be omitted.
