Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to position marking information such as the position of a land or a road or the boundary of a land or a surveying point, and information on a buried object such as a cable, a water pipe, a gas pipe or a sewer pipe buried in the ground. The present invention relates to a sign used to sign a sign.

[0002]

2. Description of the Related Art An ordinary sign has a sign indicating various kinds of information on an upper surface of a sign body. When this sign is installed on a road or the like where vehicles and people pass, if it protrudes from the ground, it hinders the passage of vehicles and people, and the sign may be kicked or damaged. Therefore, it is preferable to provide the indicator so as not to protrude from the ground.

For this reason, conventionally, a sign is attached to the ground by the following method. First, using a core drill having a cylindrical cutter and a center drill, as shown in FIG. 4A, a hole G1 formed by the center drill and an annular groove G2 formed by the cylindrical cutter are formed. Thereafter, a part G0 of the ground surrounded by the groove G2 is scraped off with a rag and a hammer. next,
As shown in FIG. 2B, a space S in which a part of the ground is cut off
0, the sign body 1 is installed, and this is
1 is fixed to the ground G. This anchor bolt 51
Consists of a bolt part 52, an outer cylinder 53 having a plurality of slits in the longitudinal direction, and a nut part. Then, after inserting the anchor bolt 51 into the insertion hole 15 formed in the main body 1 and inserting the nut part 54 downward and halfway through the hole G1,
The bolt portion 52 is pulled up so that the nut portion 54 bites into the inside of the outer cylinder 53 so as not to rotate relatively. Then, bolt part 5
2, the nut portion 54 is further cut into the inside of the outer tube 53, thereby opening the slit of the outer tube 53, and further widening the bottom portion so as to bite into the peripheral surface of the hole G1. Fix it.

However, according to the above-mentioned method, it is necessary to perform a hanging operation using a rag and a hammer to attach the indicator to the ground, so that the workability is poor.

Therefore, the present inventor has previously proposed a signage which has good workability and high rigidity, and which can perform position confirmation and information confirmation without contact using a magnetic detector (Japanese Patent Application No. 9-279,197).
No. 237085). As shown in FIG. 5, the indicator has a cylindrical shape having an upper wall 2 exposed on the surface of the ground where a window 23 is formed, and a peripheral wall 3 extending downward from a peripheral edge of the upper wall 2 and embedded in the ground G. A main body 1 is provided, and a marking body 40 including a magnetic identification body 41 and a cap 42 is provided above the main body 1.
The magnetic discriminator 41 is made of a resonance substance and a magnetic material,
An electromagnetic wave having a specific frequency (resonance frequency) is generated using a magnetic resonance phenomenon when a magnetic field is applied from a magnetic detector. The cap 42 is formed of a non-magnetic material.
When the indicator is installed on the ground G, an annular groove G2 is formed using a cylindrical core drill.
The peripheral wall 3 is embedded in 2. In addition, on the upper surface 45 of the magnetic identification body 41, sign information such as characters and designs is printed. In the figure, G11 is a positioning hole of the core drill.

[0006]

According to the above-mentioned indicator, the workability is improved because the conventional hanging operation is not required, and the main body 1 has the upper wall 2 and the peripheral wall 3,
The rigidity is high. In addition, when position confirmation and information confirmation are performed by the magnetic detector, this magnetic detector is
1 and when the electromagnetic wave to be emitted becomes larger, it can be identified accurately and reliably by identifying it with a magnetic detector, even if the main body 1 is buried in fallen leaves, snow, soil, asphalt, etc. Can be done. However, when the main body 1 is installed on the ground G, the upper wall 2 protrudes slightly from the surface of the ground, so that the breakage of the indicator cannot be reliably prevented. In addition, the structure of the entire sign becomes complicated.

Therefore, the present invention has a simple structure and can improve the workability at the time of installing the ground, and can prevent the hindrance of traffic of vehicles and people and cause the breakage of the indicator, and can confirm the position and the information. It is an object of the present invention to provide a sign that can be performed in a non-contact manner and a method of installing the sign.

[0008]

To achieve the above object, the present invention provides a marking device and a method of installing the same, wherein at least one of positioning information and buried object information is inserted into an insertion hole formed in the ground. A magnetic discriminator in which is stored
A filler made of an adhesive material having magnetic permeability is inserted, and a sign plate having magnetic permeability and having an upper surface set to be substantially flush with the ground is adhered on the filler.

According to this configuration, after the insertion hole is formed in the ground, the magnetic discriminator and the filler are inserted into the insertion hole, and the sign plate is adhered on the magnetic disc and the filler, so that the sign is almost flush with the ground. Installed in In this way, the sign does not obstruct the passage of vehicles and people, and the sign is not kicked and damaged. Further, since the sign is formed of the magnetic discriminator, the filler, and the simple members of the sign, the entire structure is simplified, and the workability when the sign is installed on the ground is enhanced. In addition, by reading the electromagnetic waves emitted from the magnetic discriminator of the sign, it is possible to confirm the position information and the buried object information accurately and reliably.

[0010] In a preferred embodiment of the present invention, the sign plate is formed of ceramics or resin. According to this, when installing a sign on a sidewalk or the like with tiles attached,
There is no discomfort to passers-by. That is, the tile
Since it is usually formed of ceramics, the use of a sign plate made of the same material, ceramic, or a resin having a material texture close to the same material eliminates unnaturalness and does not give uncomfortable feeling to passers-by. Further, since the ceramics and the resin transmit magnetism, the position information and the embedded object information stored in the magnetic discriminator can be surely and accurately confirmed by the magnetic detector.

Further, in another preferred embodiment, the above-mentioned indicator is installed on the ground near the manhole, and the information of the buried object related to the manhole is stored in the magnetic discriminator. According to this, since water pipes, gas pipes, sewer pipes, and the like are buried under the manhole, the information of these buried objects is stored in a magnetic discriminator so that repairs and inspections of the buried objects can be performed. This is convenient when performing such operations.

The core drill 20 includes a cylindrical body 22 having a blade portion 21 at a tip. Next, the filler 12 is poured into the insertion hole 10 to an intermediate height, the magnetic discriminator 11 is placed thereon, and the filler 12 is further poured near the upper portion of the insertion hole 10. Thereafter, the sign plate 13 is placed on the filler 12 such that the upper surface thereof is substantially flush with the upper surface of the tile T, and is joined and integrated.

When the embedded object information stored in the magnetic discriminator 11 is confirmed by a magnetic detector, when the magnetic detector approaches the magnetic discriminator 41 and an electromagnetic wave to be emitted from the magnetic disc increases, this is detected. Even if the indicator M is buried with fallen leaves, snow cover, soil, asphalt, etc., the identification of the buried object can be performed accurately and reliably without contact even if the indicator M is buried with fallen leaves.

In the above-described embodiment, both the position mark information and the buried object information are stored in the magnetic discriminator 11, but only the position mark information may be stored, whereby the manhole H can be used as a substitute for the surveying pile. can do. In addition, in addition to being installed near the manhole H in an urban area, the indicator of the present invention can be installed in, for example, a suburb or a mountainous area to indicate the position of a land or a road, a boundary of a land, a survey point, or the like. Can also be applied. In this case, the magnetic discriminator 11 includes one or two pieces of information such as a parcel number of a land, that is, a cadastral number, a name of a landowner, a distance and a direction from a reference point, a longitude and a latitude, and an altitude. The combination position indication information is stored as described above. Further, in the above embodiment, the entire sign M is circular, but the sign 13 may be square. Even in such a case, it is preferable that the insertion hole 12 has a circular shape that can be easily processed.
