[Industrial applications]

 This proposal concerns plates as border markers.

[0002]

[Prior art]

 There are two types of plates on the market that are publicly available as public-private border markers, arrow-shaped and cross-crossed types. Both of them have a square shape p and are marked with an arrow 4'and a cross-shaped intersection. For the mold, we had to make two types, the diagonal arrow and the middle arrow. In addition, as shown in FIGS. 10 to 13, the installation method was also a method of fixing to a solid object such as concrete with two holes a, a opened on the plate and anchor bolts b.

In the above-mentioned installation method, first, the public-private boundary point c is determined, and after the boundary point c can be displayed on the local concrete curb or gutter with a pencil or the like, the plate p is temporarily placed there and its two holes are formed. The positions of a and a are marked on the concrete surface by a line L with a pencil or the like, and holes D'and a'are drilled there using a drill D. However, at this time, the most difficult thing is that the concrete product contains a large amount of varieties and the cutting edge of the drill D is displaced, and the position of the hole fluctuates as a result. It is easy to be unable to display the position.

That is, there were the following defects. (1) Since the shape is a quadrangle, two types of arrows, a middle arrow and a diagonal arrow, must be prepared. (2) A screw and a special bolt are used to fix it on the concrete board. You have to make a hole in it. At this time, the cutting edge of the drill slips and it is difficult to make a hole in the correct position, and if it is misaligned even a little, it will not be possible to install it. However, there are some that cause an error by the width of the plate against the true boundary point (it is easy to make a rudimentary mistake) (4) Even if it can be installed correctly When a heavy object is passed or an impact is applied, it warps up and does not serve as a boundary marker. (5) When the sign is peeled off and the next attempt is made to regenerate it, it is not possible to infer the position previously instructed from the position of the hole, so re-measurement is required.

[0005]

[Problems to be solved by the device]

 The purpose of the present invention is to eliminate the above defects.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention proposes a boundary plate marker in which a marker is marked on the surface of a marker plate where two sides are intersected to form a vertex, and a bending piece is provided on the two sides above. Boundary plate described in the above invention, which is an arrow pointing toward the apex. Boundary plate described in the first or second invention, in which the marker plate is a flat plate and the bending piece can be bent downward along the two sides. Boundary plate described in each of the first, second or third inventions in which is equal to two sides, and the bent piece bent from two sides is inserted into the cross groove cut on the concrete plate. The lower edge of the bent piece bent from the two sides of the boundary plate described in each of the first, second, third, and fourth inventions, in which a sign board is fixed to the above, is formed in a downward convex arc shape. The boundary described in the first, second, third, fourth or fifth invention respectively Constituted by a plate.

[0007]

[Action]

 In this plan, the ruler 8 is placed on the concrete board 6, the apex 8 ′ of the ruler 8 is aligned with the local boundary line B, and a pencil or the like is applied to the apex 8 ′ along the two sides 8 ″ and 8 ″ of the ruler 8. The lines L, L are drawn, and the cross grooves 7, 7 are cut and formed along the lines L, L using the diamond cutter 9 (FIGS. 4 and 5).

Then, an adhesive such as a bond is injected into the intersecting grooves 7, 7 and an adhesive is applied between the intersecting grooves 7, 7, and then the bent pieces 5, 5 of the marker plate 1 are attached to the intersecting grooves 7, 7. It is tapped into the inside and the sign plate 1 is adhesively fixed between the cross grooves 7. .

In this way, the marker 4 or the arrow 4'can be installed without deviating from the target boundary point c.

The folding pieces 5 and 5 can be bent along the two sides 3 and 3 from the imaginary line position of FIG. 1 to the solid line positions of FIGS. Then, the convex arcuate lower edges 5'of the bent pieces 5, 5 correspond in parallel without interfering with the concave arc bottoms 7'of the intersecting grooves 7, 7 by the diamond cutter 9, and the rear surface of the sign board 1 is made of concrete. It is possible to make sufficient contact with the board 6.

[0011]

【Example】

 As shown in FIG. 1, a metal plate such as a stainless steel plate or a brass plate has an isosceles triangular base 3'having an arc shape, and bent pieces 5 and 5 (imaginary lines) are formed outside the sides 3 and 3. A sheet of flat plate with the above is formed by punching, and a marker 4 indicated by an arrow 4'is stamped on the apex 2 portion, and red paint is applied to this.

The lower edges 5 ′ of the bent pieces 5 and 5 are formed in a convex arc shape, and can be bent downward with pliers or the like at the site with the two sides 3 and 3 as a boundary. It does not matter if it is bent.

The arrow 4 ′ is written along the center line between the two sides 3 and 3, and the mark 4 may be a circle, a triangle, or the like. The opening angle between the two sides 3 and 3 may be 45 °, 30 °, 60 ° or 90 ° according to the ruler 8, and the marker plate 1 may be not only triangular but also other polygons.

As shown in FIGS. 7 to 9, reverse supporting claws 5 ″ are formed on the bent pieces 5 and 5 so as to be hooked on the inner walls of the cross grooves 7, 7.

[0015]

[Effect of device]

 Since the present invention is configured as described above, it has the following effects. 1. Construction is easy and time can be shortened. 2. The target boundary point c and the mark 4 or the arrow 4'must coincide with each other. 3. The bent pieces 5 and 5 can be fixed between the cross grooves 7 and 7 so that they do not turn up or warp. 4. Since the apex 2 is sharp, only one type of arrow-shaped boundary marker is required. 5. Easy to store and transport because anchor bolts are not needed. 6. You can use a commercially available triangle ruler 8 to indicate the shape of the cut with a pencil locally. 7. Even if stripping is performed, since the intersecting grooves 7, 7 remain on the concrete board 6, it can be easily confirmed that the intersection of the intersecting grooves 7, 7 is the boundary point c. Moreover, when newly installed after that, there is no error in the position.
