[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a security sign sheet for buried objects.

[0002]

2. Description of the Related Art Conventionally, in order to display a buried position of a gas pipe, a communication cable, a power cable, or the like buried in a road or a house, etc.
Alternatively, at a predetermined interval above the buried object,
Is attached. In addition, when performing road construction or underground burial construction, the location of such existing buried objects is notified to prevent unexpected accidents, and the buried objects are effectively protected from the impact of excavating tools such as scoops. It is supposed to. By the way, such a protective sign
The surface of the elongated sheet-shaped polyethylene sheet body is oxidized by corona discharge or the like, and then the required marking characters are printed out in a planar manner with a synthetic resin enamel paint or the like. These are generally widely adopted and used.

[0003]

However, the conventional protective sign sheet constructed as described above has a simple structure and can be easily manufactured, but has a sign character portion. Since it is only printed and formed flat with paint, the paint that forms the sign character part deteriorates with time and easily peels off, and it is very susceptible to damage by contact with excavation tools etc. As a result, the original labeling function was easily lost.

This invention is intended to solve the conventional problems at once, and to provide a protection sign sheet for a buried object which can effectively exert not only a sign function but also a protection function for a long period of time. .

[0005]

That is, the present invention provides a method for
Label for buried object position display Doo body 11, 21, 31 surface
The character portions 12 and 22 are three-dimensionally engraved in an uneven shape .

[0006]

[Function] Since the sign character parts 12 and 22 are three-dimensionally engraved in an uneven shape, they are very durable, and can be protected for a long time.
Not only can the sign function be effectively exerted, but also the sign characters 12, 22 rise in the soil during excavation in road construction or the like, and the sign effect can be further enhanced.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an embodiment of the present invention. Reference numeral 11 denotes a slender plate-shaped sheet body having a required length and thickness. The sheet body 11 is formed of a material such as a synthetic resin such as polyethylene or a hard rubber having an impact resistance. . Reference numeral 12 denotes a sign character portion formed of required characters which are three-dimensionally engraved on the surface of the sheet main body 11 along the longitudinal direction thereof. In addition, 13 denotes a buried object such as a gas pipe, and 14 denotes a drilling tool such as a scoop. The colors of the sheet body 11 and the sign character portion 12 can be colored based on the Road Law Enforcement Ordinance, but other colors may be used as long as they can be distinguished from the colors of earth and sand. Any color can be used freely. It is preferable that the sheet body 11 and the marker character portion 12 are colored in different colors that can be distinguished from each other. However, even when the sheet body 11 and the marker character portion 12 are colored in the same color, the marker character portion 12 is formed in a convex shape. Therefore, there is no risk of losing the sign function.

In the embodiment constructed as described above, as in the conventional example, both ends of the gas pipe or the like are connected in series with a predetermined interval above or directly above the buried object 13 at predetermined intervals. And used for use (see Fig. 3). At this time, since the marker character portion 12 is formed in the surface of the sheet main body 11 in a convex shape, there is no possibility of deterioration as in the related art, and the marker function can be performed for a long time. And when you do road construction etc. later,
In addition to effectively protecting the buried object 13 from the impact of the excavating tool 14, the buried object 13
To prevent accidents. At this time, since the sign character portion 12 is formed in a convex shape, the sign character portion 12 is clearly combined with the color of the surrounding earth and stone, so that the sign character portion 12 can further enhance the sign function.

FIG. 4 shows another embodiment, which is different from the above embodiment in that the marker character portion 22 is formed in a concave shape, and the other portions are the same and have the same reference numerals. Indicates the same part.

In the above embodiment, the plate body 11 is formed in a flat plate shape, but the present invention is not limited to such a shape, and the plate body 21 has a semicircular cross section. (See FIG. 5) and a plate main body 31 (see FIG. 6) having a downwardly U-shaped cross section may be formed into a desired shape according to the shape of the buried object 13.

[0011]

According to the present invention, as described above, the marker character portions 12 and 22 for displaying the buried objects are three-dimensionally engraved on the surfaces of the sheet bodies 11, 21 and 31 in an uneven manner. It is extremely durable without delamination due to deterioration over time as described above, and can not only effectively exert protection and sign functions for a long time, but also sign letters when excavating in late road construction etc. The parts 12 and 22 float up in the soil, and can further enhance the sign effect.
