Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a boundary pile position display plate and a direction indicating plate used as an explicit marking plate for a boundary pile.
[0002]
[Prior art]
In general, a boundary pile 1 made of concrete is embedded in the boundary of the power plant adjustment site, the power plant or substation site, the power transmission tower site, etc., as shown in FIG. Is installed. The conventional explicit sign plate 2 is attached by attaching a white plastic plate 3 with a concrete bond, and a management number 4 is engraved or handwritten on the plastic plate 3.
[0003]
However, in places where the boundary piles 1 are buried in the mountains, they may be covered with grass, or they may collapse or flow out due to landslides. The boundary piles 1 are inspected one by one. In some cases, the location of the boundary pile 1 may not be known. In addition, when inspection was performed by patroling the boundary pile 1, the management number 4 was recorded, but there was no means for confirming whether the inspection was actually performed. In addition, a sign board with a control number is attached to the transmission line tower, and even when these towers are inspected, the management number of the checked tower is recorded, but it is confirmed whether the inspection has actually been performed. I couldn't. In addition, there is a guide sign board for the inspection route of the tower because the road is not maintained because there are almost no ordinary people on the mountain road, but when it gets dark, there is a danger that the guide sign board will be difficult to see and get lost.

[Means for Solving the Problems]
In the boundary pile position display plate according to claim 1 of the present invention, a white-type pile is displayed on one side of a pressure-sensitive adhesive sheet having a pressure-sensitive adhesive layer formed on both sides of a closed-cell plastic mat via a black plastic plate. Adhere the plastic plate, engrave the white plastic plate with a laser engraving machine, expose the black plastic plate on the back, form letters, and on the surface of this white plastic plate , It is characterized by the formation of a display surface that is displayed by two-dimensional digital data codes with dot-like light and dark patterns formed by laser baking processing of management data that records information unique to boundary piles such as numbers and position information is there.
[0006]
The position display plate for boundary piles of the present invention is attached by being crimped to the boundary pile. The pressure-sensitive adhesive sheet allows the closed cell plastic mat to adhere to the mounting surface and adhere to the entire surface even if the mounting surface has some irregularities, and the pressure-sensitive adhesive layer has adhesive strength over time after pressure bonding. It is possible to maintain a high adhesive strength over a long period of time. Although the boundary pile position display plate can be installed outdoors where the temperature changes drastically, even if the thermal expansion difference between the mounting surface and the plastic plate is large, the plastic mat of the pressure-sensitive adhesive sheet that connects them absorbs the thermal expansion difference. Therefore, peeling of the plastic plate can be prevented. The plastic mat is made of closed-cell plastic and has excellent water repellency so that rainwater does not enter here and can be prevented from being peeled off by freezing rainwater. In addition, a white plastic plate is engraved with letters or a laser engraving machine, and the black plastic plate on the back surface is exposed to form three-dimensionally, so that it can be displayed clearly over a long period of time.
[0007]
In addition, the two-dimensional digital data code formed on the display surface is a two-dimensional display of digital data with dot-like light and dark patterns inside a rectangular frame. Compared to a bar code with striped stripes, The amount of data per unit area is large, and a large amount of information can be displayed. For this reason, when an operator patrols a boundary pile to which a position display plate for boundary piles is attached, the number of the boundary piles is obtained by reading a two-dimensional digital data code displayed on the position display plate for boundary piles with a scanner . Management data that records information unique to the boundary piles, such as location information , can be read on-site and inspections can be confirmed.
[0008]
The direction indicating plate according to claim 2 is a direction indicating plate in which a plurality of boundary piles each having the boundary pile position indicating plate according to claim 1 attached to the front surface are installed along the boundary of the land and attached to the upper surface of the boundary pile. In this case, this direction indicator plate is bonded to a white plastic plate via a black plastic plate on one side of a pressure-sensitive adhesive sheet having a pressure-sensitive adhesive layer formed on both sides of a closed-cell plastic mat. A white plastic plate was engraved with an embedding machine, the black plastic plate on the back surface was exposed, and a direction indicating line indicating the boundary pile number and the direction of the boundary pile adjacent to the left and right was formed. Is.
[0009]
The direction indication line of the direction indicator plate attached to the upper surface of the boundary pile is formed toward the direction of the adjacent boundary pile, and the position indication plate for the boundary pile attached to the front surface includes the number and position information of the boundary pile. Since the unique information is recorded in the boundary pile, when the inspection of the boundary mark is performed on site, it can be visually confirmed by the direction indicating line of the direction indicating plate even if there is no drawing. The boundary pile numbers and direction indication lines are three-dimensionally formed by engraving a white plastic plate, so that they can be clearly displayed over a long period of time.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. FIG. 1 shows a cross section of the explicit sign plate 5. In the figure, reference numeral 6 denotes a pressure-sensitive adhesive sheet, which has a pressure-sensitive adhesive layer 8 formed on both surfaces of a closed-cell plastic mat 7. As the closed-cell plastic mat 7, for example, acrylic foam is used, and the thickness is preferably in the range of 0.5 to 5 mm.
[0011]
The pressure-sensitive adhesive layer 8 provided on both sides of the plastic mat 7 is, for example, a synthetic rubber-based adhesive, which has high adhesion strength to metal, plastic, wood, etc., and is excellent in weather resistance and insulation. Is. A release paper 9 is attached to the pressure-sensitive adhesive layer 8 on the back side of the pressure-sensitive adhesive sheet 6, and a white plastic plate 11 is attached to the pressure-sensitive adhesive layer 8 on the front side through a black plastic plate 10. It is joined. The black plastic plate 10 and the white plastic plate 11 are made of a material excellent in weather resistance, impact resistance, heat resistance, etc., such as AAS resin. The white plastic plate 11 is thinner than the black plastic plate 10. A board is used.
[0012]
A display surface 12 is formed on the surface of the white plastic plate 11. As shown in FIG. 3, a white plastic plate 11 is engraved on the display surface 12 with a laser engraving machine to expose the black plastic plate 10 on the back surface. As shown in FIG. A management number 4, a company mark 14, and a company name 15 are formed. A two-dimensional digital data code 16 is three-dimensionally formed on the display surface 12 by laser baking. This two-dimensional digital data code 16 includes the company name and control number, the position coordinates of the boundary pile 1, the direction and distance of the adjacent boundary pile 1, the lot number where the boundary pile 1 is located, the address of the landowner, the date of writing Information unique to the boundary pile, such as the date of embedment, is displayed in a monochrome pattern formed by the white dot portion 17 and the black dot portion 18.
[0013]
Next, the case where the explicit sign board 5 of the said structure is attached to the boundary pile 1 is demonstrated. First, as shown in FIG. 4, dust and dirt adhering to the mounting surface of the boundary pile 1 are removed, and then a primer is sprayed to smooth the concrete surface. Thereafter, the release paper 9 on the back surface of the explicit label plate 5 is peeled to expose the pressure-sensitive adhesive layer 8, and this is pressure-bonded to the attachment surface of the boundary pile 1. At this time, the pressure-sensitive adhesive sheet 6 can be adhered to the entire surface by the closed cell plastic mat 7 even if the mounting surface has some irregularities. In addition, the pressure-sensitive adhesive layer 8 has a characteristic that the adhesive strength is improved with the passage of time after pressure bonding, and can maintain high adhesive strength over a long period of time.
[0014]
The explicit sign board 5 is attached to the outdoor boundary pile 1 where the temperature changes drastically. The thermal expansion of the concrete boundary pile 1 and the black plastic board 10 is different, especially in the summer. However, since the plastic mat 7 of the pressure-sensitive adhesive sheet 6 connecting this absorbs the difference in thermal expansion, the black plastic plate 10 can be prevented from peeling off.
[0015]
Further, since the plastic mat 7 is made of closed-cell plastic, it has excellent water repellency so that rainwater does not enter here and can be prevented from being peeled off by freezing rainwater.
[0016]
In addition, when the operator patrols the boundary piles 1 ..., he carries a portable scanner and inspects them one by one according to a predetermined circuit. The operator reads the two-dimensional digital data code 16 displayed on the explicit sign board 5 with a scanner, and the company name 15 and management number 14, the position coordinates of the boundary pile 1, the direction and distance of the adjacent boundary pile 1, the boundary pile 1 The inspection can be confirmed by recording location data such as the lot number, the address of the landowner, the date of writing, the date of burial, and the management data. Also, the two-dimensional digital data code 6 displays the direction and distance of the adjacent boundary pile 1, and even if it is covered with grass and cannot be seen, collapsed due to landslide, or has flowed out, the adjacent boundary pile 1 The position can be confirmed.
[0017]
The two-dimensional digital data code 16 is three-dimensionally formed on the surface of the white plastic plate 11 by laser baking, so it has excellent durability and can be read clearly over a long period of time. The two-dimensional digital data code 16 can be read by the scanner from any direction of 360 degrees, and has the function of recovering data even if part of the code 6 is damaged or dirty, and the data is encrypted. Information can be managed in secret.
[0018]
The characters of the boundary mark 13, the management number 4, the company mark 14, and the company name 15 are three-dimensionally formed by engraving the white plastic plate 11 and exposing the black plastic plate 10 on the back surface. The characters can be clearly displayed and can be read over a long period of time even if dust adheres to the surface of the white plastic plate 11 or gets dirty.
[0019]
In addition, when the boundary pile 1 is installed on the shore of the lake, etc., it is confirmed on board the ship, but when it is located far away or in a dangerous place such as a cliff, it is If the two-dimensional digital data code 16 is photographed and displayed on a display and read by a scanner, it can be confirmed safely from a remote place without approaching a dangerous place.
[0020]
