Description

  The present invention relates to a boundary mark installation tool in the case of installing a boundary mark on a land boundary.

  Conventionally, as this kind of boundary mark installation tool, for example, there is a boundary mark installation tool disclosed in Patent Document 1. This boundary marker installation instrument consists of a survey rod equipped with a prism for determining boundary points using a surveying instrument, a boundary marker installation instrument body formed in the actual size of the boundary marker, and an upper part of the boundary marker installation instrument body. An insertion port for mounting the surveying rod is provided at the center of the plan view, at any one of the corners, or at the midpoint of any one of the sides, and a detachable case that covers the side surface of the boundary mark installation instrument body is provided.

Japanese Patent No. 5785580

  Since the boundary mark installation instrument main body described in Patent Document 1 is formed as the actual size of the boundary mark, it is located at the midpoint of one of the three insertion openings provided for mounting the surveying rod. The insertion port provided can accommodate half of the surveying rod, and the insertion port provided at the corner can accommodate only a quarter of the surveying unit, so that the surveying rod can be completely inserted at these two locations. There is a problem that the removable case has to be processed into a complicated shape. Moreover, in the structure of patent document 1, since the boundary mark installation instrument main body is utilized as an alternative member of a boundary mark, after determining the boundary point using the boundary mark installation instrument, the main body of the boundary mark installation instrument is removed. Since the boundary mark is embedded and installed in the ground, there is a problem that the boundary mark cannot be set at an accurate position.

  The present invention has been made in view of such problems, and an object of the present invention is to provide a boundary mark installation tool that can easily place a boundary mark at an accurate position with a simple structure.

  In order to solve the above-mentioned problems, the boundary marker installation instrument according to the present invention uses a bowl-shaped boundary marker installation instrument body and a surveying instrument inscribed in a square plane displaying boundary points of boundary markers indicating land boundaries. A measuring rod equipped with a prism and a level for determining the boundary point, and a central portion of the open surface of the boundary mark installation instrument body, a corner portion, and a central portion of one side forming the open surface. A holding part provided to install the surveying rod on the side opposite to the open side of the boundary mark installation tool body, and the holding part is the side opposite to the open side of the boundary mark installation instrument body A hole having a size larger than the outer diameter of the surveying rod or a cylindrical tube having a hole having a size larger than the outer diameter of the surveying rod, or the surveying rod inscribed in the surveying rod Is a cylindrical tube inscribed.

  The boundary marker installation instrument of the present invention is equipped with a simple boundary marker installation instrument body on the boundary marker, and uses a surveying instrument using a level gauge and a prism-equipped survey rod attached to the boundary marker installation instrument body. Thus, the boundary point can be easily determined, and after the boundary point is determined, the boundary mark can be set at the accurate boundary point simply by removing the boundary mark installation tool body from the boundary mark.

It is a perspective view of the boundary mark installation instrument concerning one embodiment of the present invention. It is a side view of the boundary mark installation instrument which concerns on one Embodiment of this invention. It is a top view of the boundary mark installation instrument which concerns on one Embodiment of this invention. It is a figure which shows the boundary mark which concerns on one Embodiment of this invention.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a boundary mark installation instrument according to one embodiment of the present invention, FIG. 2 is a side view of the boundary mark installation instrument according to one embodiment of the present invention, and FIG. 3 is according to one embodiment of the present invention. It is a top view of a boundary mark installation instrument. 4A and 4B are diagrams showing a boundary mark according to an embodiment of the present invention. FIG. 4A is a plan view of the boundary mark, and FIG. 4B is a side view of the boundary mark. In FIG. 4 (a), for convenience of explanation, the boundary mark display 10 at the corner of the boundary mark, the boundary point display 11 at the center of the boundary mark, and the boundary point display 12 at the center of the boundary mark are displayed on the surface of the boundary mark 8. Are shown at the same time, but one of the above three displays is displayed on the actual boundary mark. In any of these three types of boundary point display, the boundary installation instrument of the present invention is configured so that the boundary point can be accurately determined.

  As shown in FIG. 1, the boundary mark installation instrument according to one embodiment of the present invention is a square plane displaying boundary points (any one of 10, 11, 12) of boundary marks indicating land boundaries ( The prism 6 and the level 7 for determining the boundary point were mounted using a bowl-shaped boundary mark installation instrument body 4 and a surveying instrument (not shown) inscribed in the boundary mark surface 9). At the positions of the survey bar 5 and the center part of the open surface of the boundary mark installation instrument body 4 and the corners and the central part of one side forming the open surface, on the side opposite to the open surface of the boundary mark installation instrument body 4 And a holding portion (1, 2, 3) provided for installing the surveying rod 4, and the holding portion provided on the side surface opposite to the open surface of the boundary mark installation instrument body 4 It is formed with a hole having a size larger than the outer diameter of the rod.

  Since the boundary mark installation tool according to one embodiment of the present invention is configured in this way, the boundary mark 8 is covered with the boundary mark installation tool, and the positions corresponding to the three types of boundary point display of the boundary mark shown in FIG. It is possible to provide a simple method in which it is only necessary to remove the boundary mark installation tool from the boundary mark 8 after the position of the boundary mark can be determined simply by standing the measuring rod 5 and using the surveying instrument to determine the boundary point. .

  Further, as a second embodiment (not shown) of the present invention, a cylindrical shape having a hole with a size in which the surveying rod 5 is inscribed in place of the holding portion having a hole with a size larger than the outer diameter of the surveying rod 5. May be installed in the holding part (1, 2, 3).

  Furthermore, as a third embodiment (not shown) of the present invention, a cylindrical tube having a hole larger than the outer diameter of the surveying rod 5 and a hole with a size in which the surveying rod 5 is inscribed is combined. It is good also as a holding | maintenance part (1,2,3).
