Description

  The present invention visually identifies the tower number displayed for each tower in order to make it easier to identify the tower when the state of the transmission line tower and the transmission line installed in a mountainous area or the like is inspected from the air by a helicopter. The present invention relates to a tower number display method and a tower number display structure suitable for the above.

A management number is assigned to the transmission line tower so that the tower can be identified by visual confirmation when patroling from the air or from the ground.
In the past, a patrol number tag was attached to the outer peripheral surface near the top of the steel tower in order to make it easy to identify the control number for each steel tower when patrol from the air by a helicopter. A conventional patrol number tag has a structure in which a number made of Arabic numerals is written on a signboard made of a lightweight and highly durable resin such as an FRP plate, and has a structure such as a quadrangular prism or a pyramid-shaped steel tower top. It was fixed with metal fittings on two or four sides facing each other.
However, the closer to the top of the tower, the smaller the area where the inspection number tag can be fixed, so the area of the inspection number tag is limited and the characters that can be displayed become smaller, and it is written on one inspection number tag As the number of digits to be increased increases, the individual numbers become smaller, so that interpretation from the air tends to be difficult. Further, since the inspection number tag is made of a plate material, the pressure received from the wind and rain increases, and there is a problem that it is easily damaged and has a short life. Further, since the mounting bracket is also in an environment where it is easily corroded and damaged, it is necessary to replace the inspection number tag in a relatively short period of time. Since exchanging the inspection number tag is a work at a high place, it is not only a dangerous operation requiring a great deal of labor, but also has a problem that the cost of the inspection number tag becomes enormous. Furthermore, there was a risk that the inspection number tag would fall due to a decrease in wind pressure and durability.

Patent Document 1 discloses a tower number display method that replaces a conventional patrol number tag. In this display method, the tower number is used for patrol from the ground by walking, by selectively painting the paint based on the rule to display a certain numerical value for the main pillar, horizontal support and oblique support that make up the tower. To be able to confirm. According to this, since the steel tower number is colored so that the steel tower number can be recognized, there is no problem of durability such as breakage due to wind pressure or the problem of increase in the number of replacements.
However, in this prior art, the shape of arithmetic numbers such as Arabic numerals is not actually displayed on the steel tower. For example, when the numbers 0 to 9 are colored on the upper left of the main pillar, it means 1. If there is coloring on the upper left of the diagonal support material, it means 2 and so on, and the correspondence is artificially determined individually, and the colored iron material is checked to check which number corresponds to the figure There is a need to. For this reason, even when checking from the ground, it takes time to check the numbers meant by the colored iron materials, and it is difficult to read the tower number. In particular, it is clear that it is more difficult to judge the numbers if the colored state of each iron material is observed in the air patrol as a confirmation work from a distance. In addition, in Patent Document 1, since the confirmation work by a patrolman on foot is assumed, the place where the number is displayed must be a relatively low place, and the number display place is obstructed by the tree and is unreadable. There are many cases.

As described above, in the conventional tower number display method, it is not colored so that it can be understood immediately at first glance, such as Arabic numerals, but it is colored based on certain artificial rules. In addition, it was not easy for patrolmen to identify and understand the numbers immediately by visual inspection, because each iron material was only arranged to mean a specific number by assigning a specific number to each iron material. . In particular, in the patrol from the air, it is necessary to confirm from a distance, so it is more difficult to understand the numbers that the colored portion means.
The present invention has been made in view of the above, and colored iron materials constituting a steel tower so as to represent large Arabic numerals that can be confirmed at a glance so that they can be easily read even in aerial patrol using a helicopter. The object is to provide a tower number display method and a tower number display structure that can be applied.

In order to achieve the above object, the tower number display method of the present invention is a tower number display method for displaying a tower number by coloring an iron material constituting a power transmission line tower, and the tower includes two vertical members. And a rectangular frame composed of two cross members, and two diagonal members fixed in an X shape along two diagonals of the frame, the numerical display region Any one of the Arabic numerals from 0 to 9 is displayed by selectively coloring each of the six iron materials constituting the material.
Since it is possible to display a shape that can be recognized as an Arabic numeral using six iron materials, it is possible to read the numeral at a glance. In addition, since one number display area indicates one number, a large number that can be easily viewed can be displayed. By using a rule that varies the number of digits displayed in the number display areas with different height positions, individual numbers can be enlarged even if the number of tower numbers increases. Reading from is easy.

The tower number display structure of the present invention includes a rectangular frame composed of two vertical members and two cross members, and two diagonal members fixed in an X shape along two diagonals of the frame. And a tower number display structure in a transmission line pylon having a number display area consisting of 0 to 9 by selectively coloring each of the six iron materials constituting the number display area. Any Arabic numeral is displayed.
The tower number display structure of the present invention is characterized in that the number display areas are provided on two opposing surfaces of the transmission line tower having a substantially quadrangular prism shape or a substantially quadrangular pyramid shape, respectively.
The tower number display structure of the present invention is characterized in that only the surface of each iron material is colored.
By coloring only one surface (front surface) of each iron material, the colored portion cannot be confirmed when viewed from the back surface side, so that it can be prevented from being misidentified as an iron material constituting another numerical display area.

  In the present invention, a specific framework structure provided at the base of the arm for supporting the transmission line of the steel tower is used as a numerical display area to color the iron material, thereby displaying large numbers that can be recognized as Arabic numerals. . For this reason, even in the air patrol using a helicopter, it can be easily read.

Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings.
FIG. 1 is an explanatory diagram showing an overall view of a steel tower displaying a tower number (123) by a tower number display method according to one embodiment of the present invention, and FIG. 2 is a display method (steel number display structure) according to the present invention. It is explanatory drawing which shows an example.
The power transmission line tower 1 is composed of a leg 2 fixed to the ground or the like, a main body 3 extending upward from the leg, and an arm 4 projecting laterally from the main body 3 to support the power transmission line C. And, it has a configuration in which iron materials (angle materials, square pipes, H-type iron materials, etc.) are assembled vertically, horizontally and diagonally. The main body 3 has a quadrangular prism shape or a quadrangular pyramid configuration.

Further, as shown in the drawing, the portion of the main body 3 to which the arm 4 is fixed includes two vertical members (iron material = main material) T1, T2 and two cross members (iron material = horizontal support material) Y1, Y2. And a number display area 20 comprising two diagonal members (iron material = diagonal supporting members) S1 and S2 fixed in an X shape along two diagonal lines of the frame 10. ing.
The portion of “rectangle + X” made of six iron materials used as the number display area 20 is a steel structure generally possessed by existing transmission line towers. In the present invention, by utilizing the “rectangular + X” -shaped steel structure common to all steel towers, by selectively applying coloring that can be visually recognized at a glance as Arabic numerals, it is possible to see from far away regardless of the air or the ground. It is designed to display numbers that can be easily read even during patrols.

The characteristic configuration of the present invention is the Arabic numeral font indicating the tower number by selectively coloring (indicated by bold lines) the iron materials T1, T2, Y1, Y2, S1, and S2 constituting the transmission line tower. More specifically, it is possible to selectively color each of the six iron materials T1, T2, Y1, Y2, S1, and S2 constituting the numerical display area 20 by 0 to 0. Any Arabic numerals up to 9 are displayed.
In the steel tower shown in FIG. 1, the number display areas 20 are arranged at three places having different heights corresponding to each arm 4. For example, the lowest number display area is used to indicate the first place. The second number display area is used to indicate the tens place, and the uppermost number display area is used to indicate the hundreds position. Alternatively, conversely to the above, the uppermost stage may be the first place, and the tenth place and the hundredth place may be sequentially provided.

  As described above, the “rectangular + X-shaped” number display area 20 is provided on the other two side surfaces other than the side surface of the main body 3 supporting the arm, and thus the number display area 20 provided on each of the two side surfaces is configured. It is possible to read the number of the steel tower when aerial inspection is performed from two opposite directions by coloring the surface side (outside) of the iron material to be performed. If the back side (inside) of the iron material constituting the number display area 20 is also colored, it may be the iron material included in the number display area on the near side in the confirmation work from one direction, or the number display on the opposite side. Since it is misunderstood or confused as to whether or not it is an iron material included in the region, it is preferable that the colored surface of each iron material is only on the surface side. In addition, since the patrol by the helicopter is performed while moving along the transmission line C, coloring each surface (outside) of the number display area 20 provided on each of the two side surfaces to which the arm 4 is not fixed is performed. Become.

Next, by coloring the six iron materials constituting the number display area based on FIG. 2 with paints (conspicuous colors different from the iron materials, for example, red, yellow, orange, etc.), Arabic numerals 0 to 9 are obtained. The displayed example will be described.
First, when the number “1” is displayed, the entire surface of one longitudinal member T1 (or T2 is acceptable) of the six iron members is colored. Since one vertical member T1 is colored in a color different from that of other iron members, the observer can easily recognize that it is the number “1” by looking at this.
When the number “2” is displayed, the number “2” can be formed by coloring the two cross members Y1 and Y2 and the diagonal member S1 and drawing a Z-shape.
When the number “3” is displayed, the number “3” can be formed by coloring only the two horizontal members Y1 and Y2 and the right half of the two diagonal members S1 and S2.
When the number “4” is displayed, the number “4” can be formed by coloring the longitudinal member T1, the transverse member Y2, and the diagonal member S1.
When the number “5” is displayed, the number “5” can be formed by coloring the cross members Y1, Y2 and the diagonal member S2.

In the case of displaying the number “6”, the number “6” can be formed by coloring the horizontal member Y2, the diagonal material S1, and the lower half of the diagonal material S2.
When the number “7” is displayed, the number “7” can be formed by coloring the cross member Y1 and the diagonal member S1.
When displaying the number “8”, the number “8” can be formed by coloring the cross members Y1 and Y2 and the diagonal members S1 and S2.
When the number “9” is displayed, the number “9” can be formed by coloring the cross member Y1, the diagonal material S1, and the upper half of the diagonal material S2.
When the number “0” is displayed, the number “0” can be formed by coloring the vertical members T1 and T2 and the horizontal members Y1 and Y2.

  According to the above display examples, it is possible to display shapes that can be recognized as Arabic numerals using six iron materials, so it is obvious at a glance without using a cumbersome display method such as assigning numbers for each iron material The number can be read with. In addition, since one number display area indicates one number, a large number that can be easily viewed can be displayed. By using a rule that varies the number of digits displayed in the number display areas with different height positions, individual numbers can be enlarged even if the number of tower numbers increases. Is easy to read.

Moreover, since the height position of the lowermost number display area 20 provided corresponding to the lowermost arm 4 is normally set to be higher than the height position of the tree extending from the ground, There is no problem that it is difficult to interpret because it is shielded by trees.
Further, according to the tower number display structure of the present invention, there is no damage or drop due to wind pressure or the like, no replacement is required, and labor can be reduced and costs can be reduced.
The number display area 20 may be colored during normal painting work for existing steel towers, and new steel towers may be colored at the time of manufacture.
According to the display method (steel number display structure) according to the present invention, tower number display that is easy to interpret can be performed not only during aerial patrol using a helicopter but also during patrol from the ground.

It is explanatory drawing which shows the whole figure of the steel tower which displayed the steel tower number by the display method of the steel tower number which concerns on one Embodiment of this invention. It is explanatory drawing which shows an example of the tower number display method (steel number display structure) by this invention.
