Description

  The present invention relates to a power transmission accident in which a snake climbs an angle member, a pipe member, and a columnar column (electric pole) that constitute a power transmission tower, and is caused by a ground fault or short circuit due to contact with a transmission line and a transformer. The present invention relates to a member for preventing the trouble and a member mounting method.

  Electricity generated at the power plant is supplied by a transmission line at a high voltage via a substation, etc., and transmission towers that support the transmission line are installed at various places. The transmission line supported by the power transmission tower is subdivided, and thereafter supported by the power pole and sent to a predetermined place. As shown in FIG. 24, the power transmission line 35 and the power transmission tower 30 are joined with an insulator 31 interposed therebetween. The insulator 31 is an insulator and prevents the flow of electricity from the power transmission line 35 to the power transmission tower 30. In addition, an arc horn is installed between the power transmission line 35 and the power transmission tower 30 to protect the electrical equipment from the abnormal high voltage applied to the power transmission system. The form of the arc horn is composed of two rod-shaped conductors. The arc horn 32 and the arc horn 33 extend in parallel with the insulator 31 and a space is formed between the two arc horns. The arc horn 32 extending from the connecting portion 34 between the power transmission line 35 and the insulator 31 is energized. Therefore, when the snake climbs to the vicinity of the top of the power transmission tower 30 and travels from the power transmission tower 30 to the power transmission line 35, the power transmission system is disturbed. As shown in FIG. 25, when the snake 36 touches both arc horns at the same time, the snake 36 becomes a conductor, electricity flows from the arc horn 32 to the arc horn 33, is transmitted to the power transmission tower 30, and is transmitted to the electricity of the power transmission system. Cause abnormalities in the flow. Moreover, the connection part 34 of the power transmission line 35 and the insulator 31 exposed to wind, rain, snow, etc. for many years has a possibility that an insulating part will deteriorate and a power transmission member may contact external air. When the snake 37 passes through the connecting portion 34 where the power transmission member appears in the outside air, the snake 37 is grounded, thereby causing an abnormal flow of electricity. In addition, a transformer that steps down the high voltage is installed on the top of the utility pole, and the snake climbs on the utility pole and makes contact with the earth leakage part of the transformer to cause a ground fault. Anomalies in the flow. When the power transmission system senses such anomalies, the substation's chatter is turned off, causing a power outage. A power transmission accident caused by a snake is one of the causes of accidents that occur at a higher rate than other causes, and it has been pointed out that it is necessary to take appropriate measures and measures.

  Then, the anti-snake climbing prevention tool for preventing the climbing of the snake to a power transmission tower and a utility pole is considered (for example, patent document 1). The rising prevention tool described in Patent Document 1 has a configuration in which a divergent shape is formed at one end portion of a member formed of a cylindrical cavity. This rising prevention tool is installed by splitting it into two equal parts in the longitudinal direction and sandwiching the angle material of the power transmission tower between them. Ascending prevention device installed on the angle member has an umbrella part that spreads in a divergent shape at one end, and the snake that ascends the angle member from the ground can get over the umbrella part. Therefore, the ascending tower can be prevented.

In addition, in a snake climbing prevention device related to a cylindrical structure material such as a utility pole, a technique for preventing the snake climbing by winding a net material around the cylindrical structure material in a divergent shape is disclosed (Patent Literature). 2). The snake-climbing prevention device disclosed in the above-mentioned Patent Document 2 forms an umbrella portion by winding a net material around a power pole in a divergent shape toward the ground. As a result, the snake climbing up the utility pole cannot get over the umbrella and prevents the snake from climbing up.
JP 2001-309532 A JP-A-8-308462

  However, the techniques according to Patent Document 1 and Patent Document 2 both attach an umbrella-shaped member to a steel tower or utility pole. The umbrella-shaped member is easily affected by the wind, and there is a high possibility that the umbrella-shaped member is damaged or detached by the strong wind. Therefore, the techniques according to Patent Document 1 and Patent Document 2 have a problem in terms of long-term reliability.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide a snake climbing prevention effect that is stable over a long period of time, and to take ground fault prevention measures.

In order to achieve the above object, the present invention has the following features.
1st invention is the snake transmission tower prevention method which concerns on the sticking method of the snake rising tower prevention sheet | seat with respect to the transmission tower which has a cross-sectional L-shaped tower column. The snake tower prevention sheet used in the present invention has hemispherical protrusions on the surface. A specific method for sticking a snake tower prevention sheet is a snake tower prevention sheet at a predetermined range in the longitudinal direction of the tower column of the power transmission tower, at both ends in the width direction of the tower column, and at the mountain side of the bent portion. Is a method of sticking a snake-rise tower preventing sheet.

  In the second invention, a power transmission tower generally has a plurality of main tower columns connected to the ground, and an auxiliary tower column connecting the plurality of main tower columns. Therefore, the present invention is a snake tower characterized by sticking a snake tower prevention sheet to both ends in the width direction of the main tower column and to the mountain side portion of the bent portion at least in a predetermined range of the main tower column. This is a method of applying a prevention sheet.

  The third invention is a plurality of main tower columns connected to the ground, and an auxiliary tower column that is installed so that the mountain side of the bent portion is on the upper side with respect to the valley side, and connects the plurality of main tower columns. In the power transmission tower structure, the snake tower prevention sheet is affixed to both ends in the width direction of the auxiliary tower column and the mountain side part of the bent portion at least in a predetermined range of the auxiliary tower column. Is a method of sticking a sheet for preventing a snake climbing tower.

  4th invention is the transmission tower structure installed so that the mountain side of a bending part may become the bottom with respect to a valley side, The width direction of the said auxiliary tower column is in the predetermined range regarding the longitudinal direction of an auxiliary tower column. A method for sticking a snake tower prevention sheet, characterized in that a snake tower prevention sheet is attached to both ends and a valley side portion of a bent portion.

  5th invention is the sticking method of the snake tower prevention sheet with respect to the power transmission tower which has a column-shaped tower pillar. The power transmission tower according to the present invention is provided with a snake tower preventing sheet on the upper part and the side part of the tower pillar in a predetermined range with respect to the longitudinal direction of the tower pillar installed to be inclined with respect to the ground from the vertically upward direction. It is a sticking method of the snake tower prevention sheet characterized by sticking.

  6th invention is the sticking method of the snake tower prevention sheet with respect to a column-shaped tower column. In the tower column according to the present invention, a plurality of elevating metal fittings are mounted at equal intervals on the bus bar of the tower column, and a snake ascending tower preventing sheet is provided on both sides of a line segment connecting any two of the nearest elevating metal fittings. It is a sticking method of the snake tower prevention sheet characterized by sticking.

  The seventh invention is affixed with the snake tower preventing sheet according to the sixth invention, and within the predetermined range of the sixth invention, the snake tower preventing sheet according to the sixth invention with respect to the central axis of the tower column. A method for sticking a snake tower prevention sheet, characterized in that a snake tower prevention sheet is also attached to the back surface of the attached part.

  In the eighth invention, a release paper divided into a plurality of parts is bonded to the adhesive surface of the snake tower prevention sheet, and a step of peeling a part of the plurality of release papers and an exposure by peeling The method for sticking a snake tower preventing sheet is characterized in that the snake tower preventing sheet is stuck by repeating the step of bonding the bonded surface to the tower column.

  According to the present invention, unlike the conventional snake transmission tower and pole prevention technology, equipment that protrudes from the tower and utility pole is not used. Doing so does not reduce the work efficiency of workers. In addition, the sheet for preventing the snake climbing tower used in the present invention causes the scale on the belly side of the snake to slip by specially processing the surface portion, but slipping occurs on the human hand. Absent. For this reason, there is no danger that a worker's fall accident occurs due to the implementation of the present invention. In addition, because there is no need to use equipment that protrudes from the power transmission tower and utility poles, there is no possibility that the protruding parts will be damaged or removed by strong winds as in the past, and the effect of preventing snake climbing that is stable over a long period of time. It is possible to take measures to prevent ground faults.

  The present invention efficiently installs the snake climbing tower prevention sheet at a place necessary for preventing the snake climbing, thereby reducing the cost of the snake climbing tower prevention sheet related to unnecessary parts and further reducing the installation work. Can be planned. This is because if the snake tower prevention sheet is installed over the entire circumference of the power transmission tower structure material or the circumference of the utility pole, a very large area snake tower prevention sheet is required, resulting in an increase in cost. In addition, when a very large area snake tower prevention sheet is attached to the entire structure of the transmission tower or power pole, the adhesive surfaces of the snake tower prevention sheet are bonded to each other after the release paper of the snake tower prevention sheet is peeled off. Becomes easy to adhere and handling becomes very difficult. In addition, as the sticking area of the snake tower preventing sheet increases, it becomes difficult to stick the snake tower preventing sheet so that air does not enter between the snake tower preventing sheet and the transmission tower structure material or the utility pole during installation. When air is mixed, a bubble part is formed, and the effect of the snake tower preventing sheet is halved. The snake can engage the ventral scale (abdominal plate) with the bubble portion, and climbs the snake climbing tower preventing sheet. In addition, the bubble portion repeatedly expands and contracts due to a change in temperature, which may deteriorate and damage the snake tower prevention sheet. The difficulty and problems of the installation work as described above can be solved by the present invention.

  In addition to the above effects, the present invention prevents the climbing of the snake to the power transmission tower and the utility pole using the snake climbing tower prevention sheet. There is not much change in appearance from the state before installation. Therefore, it is possible to prevent the snake from climbing to the power transmission tower without deteriorating the beauty of the power transmission tower and the power pole.

  Hereinafter, with reference to drawings, the triangle construction method of the snake-rise tower prevention sheet concerning the 1st embodiment of the present invention is explained. Below, with reference to FIGS. 1-5, first, after explaining the movement which a snake climbs a power transmission tower, the detail of a triangle construction method is demonstrated.

  First, a general configuration of a power transmission tower (hereinafter simply referred to as a steel tower) that is a target of a snake climbing tower will be described. The configuration of the utility pole will be described later. FIG. 1 is a diagram illustrating an example of a structure of a steel tower. The steel tower has a main tower column 1 and an auxiliary tower column 2. The main tower column 1 is connected to the ground via the lower frame 3. In FIG. 1, only one set of the lower pedestal 3 and the main tower column 1 is shown, but the steel tower has four sets of the lower gantry and the main tower column. The steel tower has a quadrangular shape as a whole by joining the upper ends of the four main tower columns to each other. A transmission line is joined to the top of the quadrangular pyramid. Moreover, in order to increase the bonding strength of the main tower column and the strength of the main tower column, the auxiliary tower column 2 is connected so as to connect the main tower column. The main tower pillar 1 and the auxiliary tower pillar 2 are iron pillars having an L-shaped cross section, and specifically, are equilateral sides obtained by bending a rectangular steel plate at about 90 degrees with a center line parallel to the longitudinal direction. Angle steel (so-called angle). The auxiliary tower column 2 is smaller than the main tower column 1. Hereinafter, both ends in the short direction (width direction) of the angle (the main tower column 1 or the auxiliary tower column 2) are referred to as “edge portions”, and the bent portions of the angles are referred to as “folded portions”.

  Next, the climbing motion when the snake climbs the steel tower as described above will be described. As a result of research by the inventors of the present application, it has been discovered that a snake does not rise while winding a body around an angle, but rises while meandering the angle of a steel tower. According to the research, it has been found that the movement patterns in which the snake climbs the angle of the steel tower are the four patterns shown in FIGS. Hereinafter, with reference to FIG. 2 to FIG. 5, the details of the snake climbing motion to the steel tower will be described. Details of the climbing exercise on the utility pole will be described later.

  FIG. 2 is a diagram illustrating a first climbing tower movement pattern. The first ascending movement pattern to the main tower column 1 of the steel tower is a pattern in which the tower ascends with the edge portion 4 of the main tower column 1 interposed therebetween. That is, as shown in FIG. 1, the snake supports itself on the main tower column 1 by sandwiching the edge portion between the bodies, and ascends the tower while preventing it from falling. When starting to ascend to the steel tower from the ground surface, the snake stretches the head upward from the ground surface along the main tower pillar 1 and, when extended to a certain extent, presses the body from both sides of the main tower pillar 1 near the edge portion 4. To sandwich the edge portion 4. The portion thus sandwiched becomes the first support location. In addition, when a snake pinches | interposes the edge part 4, not only the force which presses the main tower column 1 with its own abdominal muscle, but also a scale (abdominal board) on the ventral side is hooked on the unevenness of the paint surface of the main tower column 1 By supporting the body. When the first support portion is formed, the snake draws the body on the caudal side upward from the first support portion, and when the caudal body is pulled to some extent, the edge portion below the first support portion. Between the caudal body. The portion thus sandwiched becomes the second support location. The snake body is fixed to the main tower column 1 by the first and second support points. Thereafter, the snake ascends the steel tower by repeatedly performing the operation of shifting the first support location upward and the operation of pulling the second support location upward.

  FIG. 3 is a diagram showing a second climbing tower movement pattern. The second ascending movement pattern to the main tower column 1 of the steel tower is a pattern in which the tower ascends across the bent portion 5 of the main tower column 1. That is, as shown in FIG. 3, the snake supports itself on the main tower column 1 by sandwiching the bent portion 5 between the bodies, and ascends the tower while preventing it from falling. The second ascending movement pattern differs from the first ascending movement pattern in that it rises while sandwiching the bent portion 5, but the support part is located above the main tower column at two or more places. The same applies to the point of climbing the tower by moving it.

  FIG. 4 is a diagram showing a third climbing tower movement pattern. The third ascending tower movement pattern to the main tower column 1 of the steel tower is a pattern in which the tower ascends across both edge portions 4 and 6 of the main tower column 1. That is, as shown in FIG. 4, the snake supports itself to the main tower column 1 by sandwiching both ends (edge portions 4 and 6) of the main tower column 1 with the body, and ascends the tower while preventing it from falling. To do. The third ascending motion pattern differs from the first ascending motion pattern in that the ascending tower is sandwiched between the edge portions 4 and 6 of the main tower column 1, but the main tower column is sandwiched between two or more locations. The same applies to the point of climbing the tower by moving the support part upward.

  FIG. 5 is a diagram showing a fourth ascending tower movement pattern. The fourth ascending movement pattern to the main tower column 1 of the steel tower is a pattern that ascends with the one edge portion of the main tower column 1 and the bent portion 5 interposed therebetween. That is, as shown in FIG. 5, the snake supports itself by the main tower column 1 by sandwiching one edge part 4 and the bent part 5 of the main tower column 1 with the body, and prevents the snake from falling. Ascend the tower. The fourth ascending tower movement pattern differs from the first ascending tower movement pattern in that the tower ascends while sandwiching the edge part 4 and the bent part 5 at one end of the main tower column, but at two or more places. The same applies to the point of ascending the tower by moving the supporting part upward across the main tower column.

  The snake climbs the steel tower while combining the above four climbing tower movement patterns.

  Further, the snake has scales (belly plate) in the abdomen, and the belly plate is hooked on the fine irregularities of the painted surface of the main tower column 1 during the ascending tower. That is, the snake mainly uses the scale (abdominal plate) on the ventral side as well as the force of pressing the main tower column 1 with its abdominal muscles in any of the first to fourth climbing tower movement patterns. The body is supported by being caught on the painted surface of the tower pillar. The same applies when climbing a utility pole.

  As described above, as a result of research, it was found that the snake ascends the steel tower by the method shown in FIGS. Furthermore, as a result of research, it has been found that the snake belly plate does not engage with a fine spherical shape having a diameter of about 0.05 to 1 [mm]. From the above research results, the snake climbing tower can be prevented by the snake climbing tower preventing sheet 7 as shown in FIG. Hereinafter, the details of the snake tower prevention sheet will be described.

  FIG. 6 is a cross-sectional view of the snake tower prevention sheet. As shown in FIG. 6, the snake tower prevention sheet 7 has a structure in which a plurality of layers are laminated. Specifically, the release paper 8, the pressure-sensitive adhesive layer 9, the synthetic resin base sheet layer 10, the beads A fixing layer 11 and a surface thin film layer 14 are provided. The snake tower prevention sheet 7 has a sheet-like shape having an elongated rectangular surface.

  As the release paper 8, a paper or film treated with a release agent such as silicon, wax, or a fluororesin, or a release sheet of a synthetic resin film such as polypropylene or polyethylene having release properties is used.

  The pressure sensitive adhesive layer 9 is formed on the upper surface of the release paper 8. The pressure-sensitive adhesive layer 9 is composed of an adhesive such as an acrylic resin, and is mainly composed of, for example, polybutyl acrylate, poly 2-ethylhexyl acrylate, or the like. The thickness of the pressure sensitive adhesive layer 9 is, for example, in the range of 10 to 50 [μm].

  The synthetic resin base sheet layer 10 is formed on the upper surface of the pressure sensitive adhesive layer 9. The synthetic resin base sheet layer 10 is made of plasticized vinyl chloride resin, polyester resin, polyurethane resin, or the like. The thickness of the synthetic resin base sheet layer 10 is, for example, in the range of 30 to 100 [μm].

  The bead fixing layer 11 is formed on the upper surface of the synthetic resin base sheet layer 10. The bead fixing layer 11 includes a bead adhesive coating 12 and beads 13. The beads 13 are adhered to the bead adhesive paint 12 such that a part thereof protrudes from the upper surface of the bead adhesive paint 12. Specifically, the bead fixing layer 11 spreads the beads 13 after the bead adhesive coating 12 is applied to the synthetic resin base sheet layer 10 (including printing and spraying by a sprayer) and before the bead adhesive coating 12 is dried. It is formed by doing. Thereby, hemispherical projections by the beads 13 can be provided on the upper surface of the bead adhesive coating 12. The material of the bead adhesive coating 12 is not specified as long as it has adhesiveness to the synthetic resin base sheet layer 10. For example, a vinyl chloride resin-based paint, an acrylic urethane resin-based paint, a polyester resin-based paint, or the like can be used. The amount of the beads 13 with respect to the bead-adhesive coating 12 is preferably 10% by weight or more, and is preferably in a range in which the beads 13 are kept in a dense and uniform sprayed state on the coating. The beads 13 are preferably glass beads having a diameter of 0.05 to 1 [mm] or plastic beads that are stable against the solvent in the bead-adhesive coating 12.

The surface thin film layer 14 is formed on the upper surface of the bead fixing layer 11. Specifically, the surface thin film layer 14 is formed by thinly coating a material such as a vinyl chloride resin-based paint, an acrylic urethane resin-based paint, or a polyester resin-based paint on the bead fixing layer 11. The application amount of the above material is preferably in the range of 80 to 150 g / m ² , so that the protrusion made of the beads 13 is not flattened by being applied too thickly. Thus, the snake tower preventing sheet 7 has a shape in which hemispherical protrusions are provided on the upper surface (surface thin film layer 14).

  By sticking the snake tower preventing sheet configured as described above to the tower pole or the utility pole, the snake can be prevented from climbing to the steel tower or the utility pole. FIG. 7 is a view schematically showing a contact portion between the snake belly plate 15 and the snake climbing tower preventing sheet 7.

  As shown in FIG. 7, when the snake presses the belly plate 15 against the main tower column or utility pole in order to sandwich the main tower column or utility pole with the body, the tip of the belly plate 15 is engaged with the snake tower prevention sheet 7. Try to match. However, the tip of the belly plate 15 does not engage well with the surface of the snake tower preventing sheet 7 having a hemispherical protrusion. Furthermore, since the contact area between the snake tower preventing sheet 7 and the belly plate is reduced because the snake tower preventing sheet 7 has hemispherical projections, the frictional force between the snake tower preventing sheet 7 and the belly plate 15 is also reduced. . As described above, the snake cannot support the body of the snake even if it sandwiches the portion where the snake climbing tower prevention sheet 7 is affixed, and thus cannot climb the main tower pole or the utility pole.

  As described above, the snake climbing can be prevented by sticking the snake climbing tower preventing sheet 7 shown in FIG. 6 to the main tower pole or the utility pole. Therefore, it is conceivable to prevent the snake climbing tower by sticking the snake climbing tower preventing sheet 7 over the entire tower column or the entire circumference of the utility pole. However, if the snake tower prevention sheet 7 is attached over the entire surface of the main tower pole or the utility pole, the snake tower prevention sheet 7 having a very large area is required, which increases the cost. Further, when the snake tower preventing sheet 7 is applied to the entire surface, not only the amount of application work increases, but also no bubbles are generated between the snake tower preventing sheet 7 and the main tower pole or the utility pole. It becomes difficult to affix to the film, and the affixing work becomes difficult.

  From the above problem, in this embodiment, the snake tower prevention sheet 7 is stuck only on an appropriate part of the main tower column or an appropriate part of the utility pole. Thus, the snake climbing tower preventing sheet 7 can be efficiently attached to a necessary place, and the attaching operation can be simplified. Details will be described below. In addition, the sticking method to a utility pole is mentioned later.

  FIG. 8 is a view showing the main tower column 1 to which the snake tower prevention sheet 7 is attached. FIG. 9 is a cross-sectional view of the main tower column 1 to which the snake tower prevention sheet 7 is attached. As shown in FIGS. 8 and 9, in this embodiment, the snake tower preventing sheet 7 is attached to the edge portions 4 and 6 and the bent portion 5 of the main tower column 1. In the following description, the snake tower preventing sheet to be attached to the edge portions 4 and 6 of the angle and the snake tower preventing sheet to be attached to the bent portion 5 are distinguished, and the former is referred to as an edge snake tower preventing sheet 7a. In some cases, the latter may be used as the bent portion snake tower prevention sheet 7b. Moreover, when not distinguishing both especially, it describes with the snake tower prevention sheet 7 only.

  As shown in FIGS. 2 to 5 described above, it has been found that the snake ascends with the edge portions 4 and 6 of the main tower column 1 and the bent portion 5 sandwiched between the bodies. Therefore, in order to prevent the snake climbing tower, the snake climbing tower preventing sheet 7 may be attached to the portions 4 to 6 of the main tower column 1. Specifically, for each of the edge portions 4 and 6, the snake tower prevention sheet 7 is pasted by a predetermined width with the edge portion being substantially the center in the width direction of the tower column. That is, the snake tower prevention sheet 7 is stuck to the both sides of the edge part by a predetermined width. On the other hand, as for the bent portion 5, the snake ascends with a mountain side surface of the bent portion (hereinafter referred to as “mountain side bent portion”) interposed therebetween, so that the bent portion is bent on the mountain side surface. The snake tower prevention sheet 7 is pasted by a predetermined width around the line.

  Hereinafter, the method of attaching the snake tower prevention sheet 7 to the three portions of the iron pillar is referred to as a “triangle method”. By this triangle construction method, the snake climbing tower prevention sheet can be efficiently used to prevent the snake climbing tower. That is, since the snake tower prevention sheet 7 is not attached to unnecessary portions, the cost of the necessary snake tower prevention sheet 7 can be reduced and the application area can be reduced, so that the application work is facilitated. At the same time, the pasting operation can be simplified. In this embodiment, the snake tower prevention sheet is attached only to the main tower column. However, as in the second embodiment described later, the snake tower prevention sheet may be attached to the auxiliary tower column. Good.

  8 and 9, the vertical dimension (length in the height direction) of the snake climbing tower preventing sheet 7 is determined by the type (size) of the snake for which the climbing tower is assumed. For example, when it is assumed that the blue mushroom will rise, if the vertical dimension is about 1000 [mm], most blue mushrooms will not be able to support the body at two or more angles, and will rise. It was experimentally found that it was impossible. In addition, although the full length of Aodai show is about 1000-2500 [mm] and becomes 3000 [mm] at the maximum, an average full length is 1500-1800 [mm]. Therefore, it is considered that the tower can be prevented if it has a length that is at least half the total length of the snake that is expected to rise.

  Further, the horizontal dimension (length in the width direction) of the snake climbing tower preventing sheet 7 attached to the angle is determined by the type (size) of the snake for which the climbing tower is assumed. For example, it was experimentally found that the lateral dimension should be about 50 [mm] when it is assumed that the blue mushroom will rise. That is, when the snake tower preventing sheet 7 is attached to the edge portions 4 and 6, 25 [mm] from the end portion (edge portion 4 or 6) of the main tower column 1 to both sides (both sides) of the main tower column 1 What is necessary is just to affix the snake-rise tower prevention sheet 7 in the range. In addition, when the snake tower prevention sheet 7 is attached to the mountain side bent portion 5, the snake rises within a range of 25 mm from the mountain side bent portion 5 of the main tower column 1 to both sides in the horizontal direction of the main tower column 1. The tower prevention sheet 7 may be attached. By pasting as described above, it was found that most of the blue mushrooms could not sandwich the main tower column 1 with its body. The above-mentioned horizontal dimension is calculated because the average size of the green sword circumference is about 50 [mm], and the horizontal dimension of the snake climbing tower preventing sheet 7 is the snake trunk that is assumed to rise. It is considered preferable that the diameter is equal to or larger than the surrounding diameter.

  The snake tower prevention sheet 7 attached to the main tower column 1 is preferably attached to a position where the distance from the lower frame 3 to the lower end of the snake tower prevention sheet 7 is equal to or greater than a predetermined distance. This is because there is a possibility that the snake extends its head from the lower mount 3 and ascends the main tower column 1 with its body above the part where the snake climbing tower preventing sheet 7 is attached. Therefore, the predetermined distance is determined by the type (size) of the snake that is assumed to rise. For example, when it is assumed that the Aodai show rises in the same manner as described above, the ascending tower is prevented by setting the distance from the lower mount 3 to the lower end of the snake riser prevention sheet 7 to 1000 [mm] or more. It has been experimentally found that it can. In addition, it is preferable that the three sets of the snake tower prevention sheet 7 attached to the portions 4 to 6 of the main tower column 1 are attached to the same range in the longitudinal direction of the main tower column 1. By sticking in substantially the same range, it is possible to prevent climbing to an angle for any combination of the snake climbing motion patterns shown in FIGS.

  In addition, it is preferable that the snake tower prevention sheet 7 is affixed with respect to all the main tower pillars of a steel tower by the said triangle construction method. Further, the number of locations where the triangle construction method is applied to one main tower column may not be one, and the snake tower prevention sheet 7 may be attached to a plurality of locations on one main tower column by the triangle construction method. . For example, in order to prevent ascending towers from the ground, a snake ascending tower prevention sheet 7 is attached by a triangle construction method at a predetermined distance from the lower pedestal 3 of the steel tower, and ascending from a tree or structure adjacent to the steel tower. In order to prevent the tower, the snake tower prevention sheet 7 may be attached to the adjacent part (or a position above the adjacent part) by a triangle method. That is, when there are a plurality of routes through which the snake climbs, it is preferable to attach the snake climbing prevention sheet 7 so as to prevent the tower from being climbed by all routes.

  Next, the detail of the sticking method of the serpentine tower prevention sheet in a triangle construction method is demonstrated. In this embodiment, by adding a temporary fixing function to the snake tower preventing sheet 7, air mixing between the snake tower preventing sheet 7 and the main tower column 1 is prevented, and further, the snake tower preventing sheet 7 is attached. To facilitate positioning work and improve the efficiency of pasting work. Details will be described below with reference to FIGS.

  FIG. 10 is a diagram showing the back surface (release paper surface) of the snake tower prevention sheet to be attached to the edge portions 4 and 6 of the main tower column 1, and FIG. 11 is a mountain side bent portion of the angle main column 1. 5 is a view showing the back side of the snake climbing tower preventing sheet to be attached to FIG.

  As shown in FIG. 10, the release paper of the edge snake tower prevention sheet 7a is divided into three in the longitudinal direction. Here, the central release paper is defined as the central portion, and the release papers on both sides thereof are defined as both end portions. The horizontal dimension of the release paper 17 at the center is determined to be equal to the thickness of the angle steel plate, and is 10 [mm] in FIG. The lateral dimensions of the release papers 16 and 18 at both ends are the same, and for example, 20 mm in FIG. As described above, the overall lateral dimension of the edge snake climbing tower preventing sheet 7a is determined by the type (size) of the snake for which the climbing tower is assumed.

  As shown in FIG. 11, the release paper of the bent portion snake tower prevention sheet 7b is divided into two equal parts in the longitudinal direction. That is, the lateral dimensions of the release paper 19 and the release paper 20 are the same, and are 25 [mm] in FIG. As with the edge snake tower prevention sheet 7a, the overall lateral dimension of the bent portion snake tower prevention sheet 7b is determined by the type (size) of the snake that is expected to rise.

  The vertical dimensions of the edge snake tower preventing sheet 7a and the bent portion snake tower preventing sheet 7b are both 1000 [mm]. 10 and 11 show detailed dimensions, but the present invention is not limited to this. As described above, the angle steel plate is appropriately adjusted according to the size of the angle steel plate and the size of the snake that is assumed to rise.

  FIG. 12 is a diagram showing a method of attaching the edge snake tower prevention sheet 7a. As shown in FIG. 12, in the first step of the method for applying the edge snake tower prevention sheet 7a, the adhesive sheet exposed by peeling the release paper sheet 17 at the center from the edge snake tower prevention sheet 7a and peeling it. The surface (pressure-sensitive adhesive layer 9) is attached to the thickness surface of the edge portion 6 of the main tower column 1. By the first step, the positioning (temporary fixing) of the edge snake tower prevention sheet 7a with respect to the main tower column 1 is completed. In the second step, either the release paper 16 or the release paper 18 is peeled from the edge snake tower prevention 7a sheet. And the adhesion surface exposed by peeling a release paper is stuck along the surface of the main tower column 1. In the third step, the other of the release paper 16 or the release paper 18 is peeled from the edge snake tower prevention sheet 7a. And the adhesion surface exposed by peeling a release paper is stuck along the surface of a main tower column. Thus, the application of the edge snake tower prevention sheet 7a is completed.

  FIG. 13 is a diagram illustrating a method of attaching the bent portion snake tower prevention sheet 7b. As shown in FIG. 13, in the first step of the method of attaching the bent portion snake tower preventing sheet 7b, either the release paper 19 or the release paper 20 is peeled from the bent portion snake tower preventing sheet 7b. . And the adhesion surface exposed by peeling a release paper is stuck on the surface of the main tower column 1. At this time, the bent portion snake tower preventing sheet 7b is stuck so that the center line extending in the longitudinal direction of the bent portion snake tower preventing sheet 7b is located on the fold line on the mountain side of the main tower column 1. By this first step, the positioning of the bent portion snake tower prevention sheet 7b with respect to the main tower column 1 is completed. In the second step, the other release paper is peeled off, and the adhesive surface exposed by peeling is pasted along the surface portion of the main tower column 1. Thus, the sticking of the bent portion snake tower preventing sheet 7b is completed.

  FIG. 14 is a diagram for explaining the triangle method according to the second embodiment. In 2nd Embodiment, as shown in FIG. 14, the snake tower prevention sheet is stuck on both the main tower pillar 1 and the auxiliary tower pillar 2 of a steel tower. In addition, in 2nd Embodiment, the steel tower connected to the main tower pillar 1 is assumed so that the mountain side bending part 22 of the auxiliary tower pillar 2 may face upwards (so that it may become a mountain fold seeing from upper direction). .

  In the second embodiment, the same as the first embodiment is used as the snake tower preventing sheet 7 attached to each column 1 and 2. Further, when the auxiliary tower column 2 is connected to the main tower column 1 so that the mountain side bent portion 22 faces upward, the movement pattern when the snake ascends the auxiliary tower column 2 is the main tower column. It is the same as the case where 1 is climbed. Therefore, as with the main tower column 1, the auxiliary tower column 2 is attached with the snake tower prevention sheet by the above-described triangle method. That is, the snake tower prevention sheet is affixed at three locations of the edge portions 21 and 23 of the auxiliary tower column 2 and the mountain side bent portion 22. In the second embodiment, the method for attaching the snake tower preventing sheet 7 is the same as that in the first embodiment.

  Further, the horizontal dimension and the vertical dimension of the snake climbing tower prevention sheet are determined by the type (size) of the snake for which the climbing tower is assumed, as in the first embodiment. Here, when the snake tower preventing sheet to be attached to the main tower column 1 and the snake tower preventing sheet to be attached to the auxiliary tower column 2 are made the same size, the auxiliary tower column 2 is more than the main tower column 1. However, since the size is small, the auxiliary tower column 2 is smaller than the main tower column 1 in the area where the snake tower preventing sheet is not attached. Therefore, in the above case, it is more difficult for the snake to ascend the tower of the auxiliary tower column 2 than the main tower column 1.

  Moreover, when affixed to the auxiliary tower column 2, the snake tower preventing sheet is connected to the lower end of the snake tower preventing sheet 7 from the connecting portion (the end of the auxiliary tower column 2) between the main tower column 1 and the auxiliary tower column 2. It is preferable to affix to the position where the distance to the part is a predetermined distance or more. This is because there is a possibility that the snake extends its head from the connecting portion and ascends the auxiliary tower column 2 by sandwiching the auxiliary tower column 2 with the body above the snake climbing tower preventing sheet 7 attached to the auxiliary tower column 2. Similar to the first embodiment, the predetermined distance is determined by the type (size) of the snake that is expected to rise. For example, in the case of Aodai show, the snake climbing tower can be prevented by setting the distance from the connecting part to the lower end of the snake climbing tower preventing sheet 7 to 1000 [mm] or more.

  Further, the snake tower preventing sheet may not be attached to all the auxiliary tower columns of the steel tower, and the snake tower preventing sheet may be attached only to a necessary portion. The snake climbing tower preventing sheet may be attached to the auxiliary tower column that becomes the snake climbing tower route. For example, as shown in FIG. 14, when the auxiliary tower column 2 is connected between the place where the snake tower prevention sheet is attached to the main tower column 1 and the lower mount 3, this auxiliary tower column It is effective to attach a snake tower prevention sheet to 2. Further, for example, even when the auxiliary tower column 2 is connected at a location above the snake tower preventing sheet attached to the main tower column 1, the snake tower preventing sheet is attached to the auxiliary tower column 2. Affixing is also effective. This is because it is difficult to ascend the steel tower only through the main tower column 1 with a steep slope, and the snake is instinctively trying to climb the auxiliary tower column 2 with a gentle inclination. . If a snake tower prevention sheet is attached to the auxiliary tower pillar 2 connected at a location above the snake tower prevention sheet attached to the main tower pillar 1, it should be attached to the main tower pillar 1 by any chance. Even if the snake exceeds the snake climbing tower preventing sheet, the snake climbing tower can be prevented in the auxiliary tower column 2.

  In the second embodiment, the snake tower preventing sheet is attached to both the main tower pillar 1 and the auxiliary tower pillar 2, but the snake tower preventing sheet is attached only to the auxiliary tower pillar 2. Also good. Even in this case, it is possible to prevent the snake climbing tower.

  FIG. 15 is a diagram for explaining the triangle method according to the third embodiment. In 3rd Embodiment, as shown in FIG. 15, a snake tower prevention sheet is stuck on both the main tower pillar 1 and the auxiliary tower pillar 2 of a steel tower. The third embodiment is different from the second embodiment in that the auxiliary tower column 2 is the main tower column 1 so that the mountain side bent portion 22 faces downward (as viewed from above, the valley folds). It is a point connected to. A structure as shown in FIG. 15 may be employed for the purpose of providing the auxiliary tower column 2 with a function of receiving rain (rain) in order to drain rainwater that has fallen on the steel tower.

  FIG. 16 is a diagram illustrating a state in which a snake ascends the auxiliary tower column 2 in the third embodiment. In addition, FIG. 16 is the figure which looked at a part of steel tower from the top. In the third embodiment, as shown in FIG. 16, the snake can ascend on the inner surface facing upward among the surfaces of the auxiliary tower column 2 having an L-shaped angle. There is sex. That is, the snake sandwiches the edge portion 21 of the auxiliary tower column 2 and presses the body against the valley side surface (hereinafter referred to as “valley side bent portion”) 24 of the bent portion of the auxiliary tower column 2. Support the body.

  Therefore, in the third embodiment, as shown in FIG. 17, the snake tower prevention sheet 7 is attached as a triangle method. FIG. 17 is a cross-sectional view of the auxiliary tower column 2 to which a snake tower preventing sheet is attached by the triangle method according to the third embodiment. As shown in FIG. 17, the edge snake tower prevention sheet 7 a is affixed to the two portions of the edge parts 21 and 23 of the auxiliary tower column 2, and the back side snake tower prevention sheet 7 c is attached to the valley side bent part 24. Affix it. In the third embodiment, since the snake cannot climb the tower using the mountain side bent portion, it is not necessary to attach the snake climbing tower preventing sheet to the mountain side bent portion. Moreover, in 3rd Embodiment, the sticking position and dimension of the snake tower prevention sheet 7 are the same as 2nd Embodiment.

  Further, the back surface snake tower preventing sheet 7c can be attached to the auxiliary tower column 2 in the same manner as the bent portion snake tower preventing sheet 7b. That is, the release paper of the back-side snake tower prevention sheet 7c is divided into two equal parts in the longitudinal direction as in FIG. In the 1st process at the time of sticking, either one of the release paper divided into two is exfoliated from back snake tower prevention sheet 7c. And the adhesion surface exposed by peeling a release paper is affixed on the trough side bending part 24 of the auxiliary tower pillar 2. FIG. At this time, the back-side snake tower preventing sheet 7c is affixed so that the center line extending in the longitudinal direction of the back-side snake tower preventing sheet 7c is located at the fold line on the valley-side surface of the bent portion. By the first step, the positioning of the back surface snake tower prevention sheet 7c with respect to the auxiliary tower column 2 is completed. In the second step, the other release paper is peeled off, and the adhesive surface exposed by peeling is pasted along the other back surface of the auxiliary tower column. Thus, the pasting of the back surface snake tower preventing sheet 7c is completed.

  FIG. 18 is a diagram for explaining the triangle method according to the fourth embodiment. In 4th Embodiment, as shown in FIG. 18, the main tower pillar 25 and the auxiliary tower pillar 26 of a steel tower are cylindrical shape. In 4th Embodiment, a triangle construction method is applied with respect to the steel tower comprised with a column-shaped tower pillar.

  Even if the snake is a columnar tower column, it is possible to climb the tower if the central axis of the column is inclined to some extent with respect to the direction of gravity. Specifically, it has been found that the snake ascends with the upper part of the tower column having a circular cross section sandwiched between the bodies.

  Therefore, in order to prevent the snake climbing tower to the columnar column, the snake climbing tower preventing sheet 7 may be attached as shown in FIG. FIG. 19 is a cross-sectional view of the main tower column 25 on which the snake tower preventing sheet 7 is pasted by the triangle method according to the fourth embodiment. As shown in FIG. 19, when the triangle method is applied to the columnar main tower column 25, the snake tower prevention sheet 7 is composed of the upper portion 27 and the side portions 28 and 29 of the main tower column 25. Affixed to the place. Specifically, the upper portion 27 is an upper portion of the portion where the surface S <b> 1 including the central axis of the main tower column 25 and the direction of gravity intersects the side surface of the main tower column 25. The side portions 28 and 29 are two portions where a plane S2 including the central axis and perpendicular to the plane S1 intersects the side surface of the main tower column 25. The snake tower preventing sheet 7 is stuck at three places including at least the upper portion 27 and the side portions 28 and 29. As a result, the snake cannot sandwich the main tower column 25 and cannot support the body on the main tower column 25, thereby preventing the snake from rising.

  The snake ascends using the upper part of the main tower column 25. Therefore, as shown in FIG. 19, the serpentine tower preventing sheet 7 attached to the side portions 28 and 29 is not at the side portions 28 and 29 but at a position slightly shifted from the side portions 28 and 29. It is preferable to stick so that it may become a center.

  In FIG. 19, the case where the snake tower preventing sheet 7 is attached to the main tower column 25 is shown, but the same applies to the case where the snake tower preventing sheet 7 is attached to the auxiliary tower column 26. Similarly to the first and second embodiments described above, a snake tower prevention sheet is attached to only one of the main tower column 25 and the auxiliary tower column 26 in accordance with the assumed snake climb tower route. You may do it.

  Further, in place of the edge portion and the bent portion of the L-shaped tower column, points other than the point where the snake tower prevention sheet is attached to the upper part and the side part of the circular column tower (preventing the snake tower) The dimensions of the sheet 7, the position in the height direction where the snake tower preventing sheet 7 is attached, and the like are the same as those in the first to third embodiments.

  5th Embodiment is the installation method of the snake tower prevention sheet | seat in an electric pole.

  With reference to FIG. 20, the configuration of a utility pole to which a snake climbs in the fifth embodiment will be described. The utility pole 30 is generally a cylindrical structure having a diameter of about 300 [mm], and is installed substantially perpendicular to the ground. Near the top of the utility pole 30, a transmission line is connected with an insulator interposed. Workers of electrical work or the like need to climb the power pole 30 for repairing or checking the transmission line. Therefore, a plurality of lifting brackets 31 are attached to the utility pole 30 on the bus 33 at equal intervals, and a plurality of lifting brackets 32 are also arranged at equal intervals on the bus 34 on the opposite side of the bus 33 with respect to the central axis of the utility pole. It is attached. The elevating metal fittings 31 and 32 are rod-shaped and project vertically from the utility pole 30. The lifting brackets 31 on the bus 33 are installed at intervals of about 900 [mm], and the lifting brackets 32 on the opposite side are also installed at the same intervals. The elevating metal fitting 31 of one bus bar 33 and the elevating metal fitting 32 of the other bus bar 34 are arranged in steps. The distance in the height direction between the lifting bracket 31 of one bus bar 33 and the lifting bracket 32 of the other bus bar 34 is about 450 [mm]. The elevating metal fitting is fixed to the electric pole 30 by being inserted into the eaves hole provided in the electric pole 30 and is detachable.

  Next, the movement when a snake climbs a utility pole will be described. As a result of the research by the present inventor, snakes can climb on a power pole as well as a steel tower while wrapping around the body, and meandering while fixing the body to the lifting bracket. It's been found. According to the research, it has been found that the movement pattern in which the snake climbs the utility pole is the two patterns shown in FIGS. Hereinafter, with reference to FIG. 20 to FIG. 21, the details of the snake climbing motion to the utility pole will be described.

  FIG. 20 is a diagram illustrating a first climbing movement pattern to the utility pole 30. In the first climbing movement pattern, the snake that has reached the lifting bracket 31 from the ground hooks the body on the lifting bracket 31, fixes the body, and extends the head to the lifting bracket 32 obliquely above. When the head reaches the next lifting bracket 32, the body on the head side is hooked and fixed on the lifting bracket 32, and the lower body is pulled up. Since then, by repeating this movement, the snake climbs the utility pole.

  FIG. 21 is a diagram showing a second climbing movement pattern to the utility pole 30. The 2nd climbing exercise | movement to the utility pole 30 is a pattern which climbs along the raising / lowering metal fitting on any one bus-line. The snake that reaches the lifting bracket 31 from the ground hooks the body on the lifting bracket 31, fixes the body, and extends the head to the lifting bracket 31 in the upward direction. Since the distance to the elevating metal fitting 31 in the directly upward direction is about 900 [mm], about half of the average size snake body is not fixed to the utility pole 30. Therefore, the snake cannot reach the elevating metal fitting 31 in the upward direction by straightly extending its head. Therefore, the snake hooks the belly plate on the fine irregularities on the surface of the electric pole while meandering, and gradually stretches the bent body. When the head reaches the next lifting bracket 31, the body is hooked on the lifting bracket 31, the body is fixed, and the lower body is pulled up. After that, the snake climbs the utility pole by repeating the movement.

  The snake climbs the electric pole while combining the above two climbing movement patterns.

  As mentioned above, since the climbing movement pattern to the electric pole of the snake could be specified, the snake climbing can be prevented by sticking the snake climbing tower preventing sheet 7 only to an appropriate part of the electric pole, In addition, simplification and efficiency of the pasting operation can be realized. Details will be described below.

  In order to prevent the snake from climbing onto the utility pole 30, first, at least one lifting bracket on one of the busbars is removed within a predetermined range where the snake tower prevention sheet 7 is attached. In a predetermined range where the lifting bracket is removed, it is possible to prevent the snake from climbing due to the first climbing motion pattern.

  Furthermore, as shown in FIG. 22, the snake tower prevention sheet 7 is affixed on both sides of the line segment L connecting the two nearest lifting / lowering brackets 31 respectively. Note that the two closest lifting brackets are lifting brackets mounted on a bus bar different from the bus bar from which the lifting bracket is removed. One of the two lifting brackets is a lifting bracket attached obliquely above the position where the lifting bracket is removed, and the other is a lifting bracket attached obliquely below the position.

  It is preferable that the ascending tower preventing sheet 7 is attached so that the ascending tower preventing sheet 7 has a length equal to or longer than the line segment L in the direction of the line segment L. That is, with respect to the longitudinal direction of the utility pole 30, the tower-preventing sheet 7 is stuck in a range including the two lifting brackets 31. For example, if the installation interval between the two lifting brackets 31 is 900 [mm], a snake tower prevention sheet having a length of 900 [mm] or more may be used. That is, the vertical dimension of the snake tower prevention sheet 7 is changed as appropriate according to the installation interval of the nearest lifting brackets. In FIG. 22, the climbing prevention sheet 7 is attached so as to be in contact with the lifting bracket 31, but the climbing prevention sheet 7 and the lifting bracket 31 are not necessarily in contact with each other. In FIG. 22, the snake climbing tower preventing sheet 7 is not affixed on the line segment L, but the snake does not have to be affixed because the head does not extend straight.

  In addition, the lateral dimension of the snake climbing tower preventing sheet 7 is preferably long (wide), but when it is assumed that the blue mushroom climbs the tower, as in the first to fourth embodiments, 50 [Mm] may be sufficient. In consideration of the second climbing movement pattern described above, the lateral dimension of the snake tower preventing sheet 7 does not need to be longer than ¼ of the circumference of the utility pole.

  As in the first embodiment, the distance from the ground to the lower end of the snake climbing tower preventing sheet 7 is preferably equal to or greater than a predetermined distance determined by the length of the snake that is expected to climb. In addition, in the fifth embodiment, when the snake tower prevention sheet 7 is affixed to a height of a person's height, a person's property (for example, an umbrella, etc.), a car, etc. There is a possibility that the snake tower preventing sheet 7 may be peeled off or damaged due to contact with 7. Therefore, it is more preferable that the lower end of the snake tower preventing sheet 7 is attached at a position where the lower end is 2000 [mm] or more from the ground.

  In addition, it is preferable to divide | segment the release paper of the snake tower prevention sheet 7 so that a part can peel similarly to the said 1st-4th embodiment.

  In the fifth embodiment, the snake tower preventing sheets 7 may be attached to a plurality of locations on one utility pole. For example, in order to prevent climbing from the ground, the snake tower prevention sheet 7 is affixed at a position several meters from the ground and to prevent climbing from a tree or structure adjacent to the utility pole. The snake tower preventing sheet 7 may be attached to a position where a tree or the like is adjacent (or a position above the portion). That is, when there are a plurality of routes on which the snake climbs, it is preferable to attach the snake climbing tower preventing sheet 7 so as to prevent climbing by all the routes.

  According to the fifth embodiment described above, snake climbing due to the first and second climbing motion patterns can be prevented.

  FIG. 23 is a diagram for explaining the triangle method according to the sixth embodiment. In the sixth embodiment, in addition to the two positions described in the fifth embodiment, the snake tower preventing sheet 7 is attached to the position where the lifting bracket 32 is removed in the fifth embodiment. In addition, even if the snake climbing tower preventing sheet 7 is attached according to the fifth embodiment, if the snake climbs while sandwiching the side of the utility pole with the body, there is a possibility that climbing cannot be completely prevented. is there. Therefore, in the sixth embodiment, the snake climbing tower prevention sea 7d is also affixed to the bus bar from which the lifting bracket is removed, so that the snake does not pinch the side surface of the utility pole and more reliably prevents climbing. To do.

  As shown in FIG. 23, in the sixth embodiment, the snake tower preventing sheet 7d is pasted on the bus bar 34 from which the lifting bracket is removed with a width equal to both sides from the bus bar 34. The snake tower preventing sheet 7d is attached so as to have the same height and the same length as the snake tower preventing sheet 7 to be attached in the same manner as in the fifth embodiment.

  Further, the lateral dimension of the snake tower preventing sheet 7d is preferably long (wide). However, when it is assumed that the blue mushroom climbs, 50, as in the first to fifth embodiments. [Mm] may be sufficient. In consideration of the second climbing motion pattern described above, the lateral dimension of the snake climbing tower preventing sheet 7d does not need to be longer than half the circumference of the utility pole.

  In addition, the sticking location to the utility pole and the number of pasting locations of the triangle method in the sixth embodiment are the same as those in the fifth embodiment.
