[0002]
[Prior art]
A utility pole display plate displaying a company mark, a utility pole number, and the like is attached to a utility pole that supports a power line, a telephone line, a power line, and the like. As shown in FIGS. 4 and 5, the conventional utility pole display plate 1 is formed by stamping an aluminum plate 2 to display a company mark 3, a utility pole number 4, etc. The band insertion holes 5 and 5 are formed on both sides. When the electric pole display plate 1 is attached to the electric pole 6, one end of the tinplate band 7 is passed through the band insertion hole 5 on one side of the electric pole display plate 1, and this is fixed with a stopper 8. 6, the other end of the tin band 7 is folded through the band insertion hole 5, and is fixed by a stopper 8.
[0003]
However, the conventional utility pole display plate 1 is attached to the utility pole 6 as shown in FIG. 5, and ends of the tin band 7 are passed through the band insertion holes 5, 5, folded and fixed by the stoppers 8, 8. Since 7a and 7a are exposed to the near side, when an operator raises or lowers the utility pole 6, the end 7a may be caught on the body and damaged, which is dangerous. Moreover, since the utility pole display plate 1 is mounted at a high position of the utility pole 6, the installation work at a high place is troublesome, and the tinplate 7 may rust and fall off the utility pole display plate 1 during long-term use. There was also. In addition, the conventional telephone pole display plate 1 displays a company mark 3 and a telephone pole number 4 by stamping an aluminum thick plate, so that the types of stamping dies are limited, and molding of fine characters and figures is performed. There was a problem that display items were limited due to failure.
[0004]
[Problems to be solved by the invention]
The present invention eliminates the above-mentioned drawbacks, can display many items, is easy to attach to a utility pole, is safe without being injured by an operator when raising and lowering the utility pole, and has long-term durability. It is intended to provide an electric pole display plate excellent in the above.
[0005]
[Means for Solving the Problems]
The utility pole display plate according to claim 1 of the present invention is obtained by joining a flexible stainless thin plate to one side of a pressure-sensitive adhesive sheet in which a pressure-sensitive adhesive layer is formed on both sides of a closed-cell plastic mat. On the surface of the thin plate, a two-dimensional digital data code displaying utility pole information in a dot-like light and dark pattern and a display surface displaying utility pole numbers are formed, and the two-dimensional digital data code forms a dark dot portion by laser printing. The white dot portion is formed by exposing the stainless steel thin plate .
[0006]
When attaching the utility pole display plate of the present invention, the mounting surface of the utility pole is first cleaned, and then the primer is sprayed to smooth the surface. Thereafter, the release paper on the back surface is peeled off to expose the pressure-sensitive adhesive layer, and this is attached by being crimped while being curved along the mounting surface of the utility pole. The utility pole display plate is attached to an outdoor utility pole, and the utility pole and the stainless steel thin plate have different thermal expansions, but the plastic mat interposed between them absorbs the thermal expansion difference, so that peeling can be prevented. Moreover, since the plastic mat is made of closed-cell plastic, rainwater does not enter here, and peeling can be prevented. In addition, the stainless steel plate has excellent corrosion resistance, and the display surface provided on this surface is formed by applying a cut sheet with an adhesive applied or by laser baking, so it has excellent durability without peeling for a long time. Yes.
[0007]
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 one-dimensional barcode 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 the power pole with the power pole display plate attached, the operator can check the power pole information and inspection by reading the two-dimensional digital data code displayed on the power pole display plate with a scanner. . The 2D digital data code can be read by the scanner from any direction of 360 degrees, and it has a function to recover the data even if part of the code is damaged or dirty, and it encrypts the data. Information can be managed in secret.
[0008]
In addition, this two-dimensional digital data code can form dark dot parts in black, brown, dark blue, red, etc. and white dot parts can be formed by exposing a thin stainless steel plate, so it has excellent corrosion resistance and can be read reliably over a long period of time. Can
[0009]
The utility pole display plate according to claim 2 is characterized in that the plastic mat has a thickness of 0.5 to 5 mm and the stainless steel plate has a thickness of 0.01 to 0.1 mm.
[0010]
In the present invention, the thickness of the plastic mat is set in the range of 0.5 to 5 mm. If the thickness is less than 0.5 mm, the unevenness of the electric pole surface is caused when the electric pole display plate is pressed against the electric pole. It is difficult to get familiar with the part, it cannot adhere to the whole surface, and there is a risk of peeling because it absorbs less thermal expansion. On the other hand, if the thickness exceeds 5 mm, cracks are likely to occur when bent along the pole surface, and rainwater may enter from here. In the present invention, the thickness of the stainless steel sheet is set to 0.01 to 0.1 mm. If the thickness is less than 0.01 mm, it is easy to crack when an impact is applied, and if it exceeds 0.1 mm, the flexibility becomes poor. This is because the utility pole display plate is difficult to adhere to the utility pole surface.
[0011]
The utility pole display plate as claimed in claim 3, and characterized in that the utility pole number of the display surface is formed Ri by a plastic sheet coated with adhesive cut sheet was cut into a predetermined shape or laser baking process, Therefore, the characters are clear and can be clearly distinguished without peeling for a long time.
[0012]
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 a utility pole display plate 10. In the figure, reference numeral 11 denotes a pressure-sensitive adhesive sheet, which has pressure-sensitive adhesive layers 13 and 13 formed on both surfaces of a closed cell plastic mat 12. As the closed-cell plastic mat 12, for example, acrylic foam is used, and the thickness is preferably in the range of 0.5 to 5 mm.
[0013]
The pressure-sensitive adhesive layers 13 and 13 provided on both sides of the plastic mat 12 are, for example, synthetic rubber adhesives, which have high adhesion strength to metals, plastics, wood, etc., and are excellent in weather resistance and insulation. It is what. A release paper 15 is attached to the pressure-sensitive adhesive layer 13 on the back side of the pressure-sensitive adhesive sheet 11, and a stainless steel thin plate 14 is bonded to the pressure-sensitive adhesive layer 13 on the front side.
[0014]
The thickness of the stainless steel thin plate 14 is preferably 0.01 to 0.1 mm. As shown in FIG. 2, the stainless steel thin plate 14 has a display surface formed of a cut sheet obtained by cutting a plastic sheet into a predetermined shape. 16 is formed. For example, a company mark 3, a utility pole number 4, a wire name 17, and a wire type 18 are formed. This cut sheet is obtained by, for example, applying an adhesive to the back surface of a vinyl chloride sheet, cutting it into an arbitrary shape with a cutting machine, and pasting it on the surface of the stainless steel thin plate 14. In addition, the display surface 16 is formed with a two-dimensional digital data code 19 that shows various information such as a telephone pole number, electric wire name, electric wire type, electric wire position, and installation date of the electric pole in a dot-like light / dark pattern. Yes. In this case, the two-dimensional digital data code 19 is formed by performing laser printing to form a black dot portion, and the white dot portion is formed by exposing the stainless steel thin plate 14 on the back side between the black dot portions.
[0015]
Next, the case where the electric pole display plate 10 having the above configuration is attached to the electric pole 6 will be described. First, after dust and dirt adhering to the mounting surface of the utility pole 6 are removed, a primer is sprayed to smooth the surface. Thereafter, the release paper 15 on the back surface of the utility pole display plate 10 is peeled off to expose the pressure-sensitive adhesive layer 13, which is crimped while being curved along the attachment surface of the utility pole 6 as shown in FIG. At this time, the pressure-sensitive adhesive sheet 11 can adhere to the mounting surface with the closed cell plastic mat 12 even if the mounting surface has some unevenness. In addition, the pressure-sensitive adhesive layer 13 has a characteristic that the adhesive strength is improved with the lapse of time after pressure bonding, and can maintain high adhesive strength over a long period of time.
[0016]
Also, the utility pole display plate 10 is attached to the outdoor utility pole 6 where the temperature changes drastically, and the utility pole 6 and the stainless steel thin plate 14 have different thermal expansions. Since the plastic mat 12 of the adhesive sheet 11 absorbs the difference in thermal expansion, it is possible to prevent the stainless thin plate 14 from peeling off. Further, since the plastic mat 12 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. Further, the stainless steel thin plate 14 is particularly excellent in corrosion resistance, and the display surface 16 provided on this surface can be clearly identified without being peeled for a long time since a cut sheet with an adhesive applied is stuck on the back surface. Combined with these actions, it has been confirmed that the utility pole display plate 10 of the present invention can maintain durability for 50 years or more even in the accelerated weather resistance test.
[0017]
Also, unlike the conventional stamping of the aluminum plate 2, the display surface 16 is pasted with a cut sheet cut into an arbitrary shape by a cutting machine, so that fine symbols and characters can be created, especially the two-dimensional digital data code 19 black dot portion formed by the laser sintering additional engineering black, white because dot portions are formed three-dimensionally to expose the back side of the stainless steel sheet 14 from between the dark dot portion, long-term durable Data can be read clearly over a wide area. The 2D digital data code 19 displays various utility pole information, such as utility pole number, utility pole type, utility pole position display, etc., so that the operator who carries out the inspection work will have a portable scanner and a utility pole. By reading and recording the two-dimensional digital data code 19 on the display plate 10, it is possible to confirm various utility pole information and inspection.
[0018]
