Description

  The present invention relates to a boundary plate. Specifically, it relates to the boundary plate as a public-private boundary sign installed on the local concrete curb or side gutter.

As this kind of boundary plate, for example, one described in Non-Patent Document 1 is known.
Specifically, the boundary plate 101 has a structure in which an arrow 103 is engraved on the surface of a rectangular brass sign plate 102 and an anchor insertion hole 104 is opened as shown in FIG.

  When attaching the boundary plate 101 to a solid object such as concrete, first, as shown in FIG. 9A, the public-private boundary point 105 is first displayed on the local concrete curb or on the side groove with a pencil or the like.

  Subsequently, with the boundary plate 101 made of brass temporarily placed and the arrow 103 aligned with the public-private boundary point 105, the position of the anchor insertion hole 104 is marked on the concrete surface with a pencil or the like, and the hole 107 is made there by a drill 106. Perforate.

  Then, as shown in FIG. 9B, in a state where the anchor insertion hole 104 of the boundary plate 101 is aligned with the hole 107 drilled in the concrete surface, the anchor 108 is driven into the anchor insertion hole 104 and the hole 107 to the concrete surface. The boundary plate 101 is fixed.

  However, in the boundary plate having such a configuration, since the method of fixing on the concrete board is performed with screws and special bolts, holes must be drilled. In this case, it is difficult for the drill tip to slip and make a hole at an accurate position, and if it is slightly displaced, installation may be impossible.

  Further, when the boundary plate is fixed with an anchor, the anchor peripheral portion is firmly pressed onto the concrete board. However, since the peripheral portion of the boundary plate has a weaker crimping force than the anchor peripheral portion (the central portion of the boundary plate), the periphery of the boundary plate may be warped when an impact due to passing of a vehicle or the like is applied.

  Here, there is a boundary plate as shown in FIG. 10 that has solved the above-described problems. More specifically, a metal plate such as a stainless steel plate or a true cast plate is used to form an arc shape of an isosceles triangle base 110, and a mark is placed on the apex portion of the sign plate 113 formed by vertices intersecting the two sides 111 and 111. 114 is written. Further, a bent piece 112 is provided outside the two sides 111 and 111.

  When the boundary plate having such a configuration is installed on a local concrete curb or a side groove, a ruler 116 is placed on the concrete 115 as shown in FIG. Then, the vertex 117 of the ruler 116 is aligned with the local boundary line 119, a line is drawn from the vertex 117 along two sides of the ruler 116 with a pencil or the like, and a diamond cutter (not shown) is used along the line. Then, the intersecting grooves 120 are formed by cutting.

  Subsequently, as shown in FIG. 11B, an adhesive such as a bond is injected into the intersecting groove 120, and the bent piece 112 of the sign plate 113 coated with the adhesive is tapped into the intersecting groove and bonded. Fix it.

  In the boundary plate having such a configuration, it is possible to prevent peripheral bending or warping by inserting and fixing the bent pieces between the intersecting grooves. In addition, by providing the intersection grooves on the two sides, the apex can be positioned easily and accurately.

  However, the boundary plates shown in FIGS. 10 and 11 are often installed near the boundary between the concrete concrete curb or the public-private boundary point on the side groove.

  In such a case, when cutting a cross groove using a diamond cutter on two sides from the apex, the concrete wall surface may also be cut with the diamond cutter. After installing the boundary plate, the concrete wall surface with mortar etc. Must be repaired.

  The present invention has been developed in view of the above points, and provides a boundary plate that can be attached to a sign plate without damaging a portion other than a cross groove into which a bent piece of the sign plate is fitted. It is intended to do.

  In order to achieve the above object, a boundary plate according to the present invention is displayed on a surface of a sign board having a rectangular shape with apexes formed by intersecting a first side and a second side. And a bent piece formed on only the third side and the fourth side, which are opposite sides of the first side and the second side, with the two sides as a boundary. With.

  Here, the first and second sides of the square-shaped marker plate having the apex formed by intersecting the first and second sides, and the third and fourth sides that are opposite to the second side Only by providing the bent pieces formed with the two sides as a boundary, for example, even when the boundary point is located in the vicinity of the wall surface, it is possible to reliably provide the cross groove on the concrete surface with the diamond cutter.

  In addition, the bent piece is configured to be bendable with the third side and the fourth side as a boundary, and when arranged on the same flat plate shape as the sign plate, a plurality of boundary plates are stacked. It becomes possible to carry.

  Further, when the open end of the bent piece is formed to project in an arc shape toward the open end direction, for example, the bent piece is provided by providing a substantially arc-shaped intersecting groove on the concrete surface with a diamond cutter or the like. Can be inserted into the crossing groove without any gap.

  Moreover, when the taper part which the surface side of the sign board inclined in the 1st edge and the 2nd edge is formed, after the boundary plate installation, the concrete surface and the first edge and the second edge of the sign board It becomes possible to eliminate the step with the side.

  In addition, when the bent piece is provided with a reverse support claw part that prevents falling out, the sign plate can be firmly attached to the concrete surface by engaging the reverse support claw part that prevents falling out to the inner wall of the crossing groove. It becomes.

  Further, when the marker plate and the bent piece are made of aluminum, it is possible to maintain the color at the time of construction without discoloration. For example, when the sign plate and the bent piece are made of brass, the color changes to a dark color with the passage of time, and the appearance becomes worse.

  In order to achieve the above-mentioned object, the boundary plate according to the present invention is displayed on the surface of the sign plate on which the apex is formed by intersecting two sides, and the direction of the apex is indicated. A marker to be indicated and a bent piece formed on only the side other than the two sides of the marker plate with the same side as a boundary.

  Here, the first side of the square shaped sign board formed by intersecting the first side and the second side and the side other than the second side are formed on the same side as the boundary. By providing the bent piece, for example, even when the boundary point is located in the vicinity of the wall surface, it is possible to reliably provide the cross groove on the concrete surface with the diamond cutter.

  The boundary plate of the present invention can be attached to the sign plate without damaging the portions other than the intersecting grooves.
