Description

[Detailed description of the device] (Industrial application field) This device is used to set a land boundary point display sign in the application site or in the adjoining site when the land boundary point display sign cannot be set across the application site and the adjacent site. The present invention relates to a multi-sided arrow-shaped land boundary point display board used to display the boundary points of.

(Conventional technology and problems) It is the job of the land and house surveyor to survey and register land and buildings, but it is necessary to conduct surveys with the highest accuracy possible in land surveying, and The boundary point must be set accurately and this boundary point must be measured accurately.

In particular, due to the social situation that land prices have risen in recent years, and improvements in surveying technology, etc., the client who makes a severe order to set a boundary sign that does not cause an error of about 2 mm to 3 mm on the boundary line or the relationship Are coming out.

Generally, in order to carry out a definite survey in accordance with the application procedure for land-separation registration, etc., as shown in Fig. 9, the above-mentioned boundary point is confirmed after the application land owner and the adjacent land owner are present, and the land boundary mark (1) is set. Set and put both confirmation marks on the witness certificate.

The line connecting the land boundary points (2) of each land boundary sign (1) becomes the land boundary line (X).

If all boundary points of the application site set as described above are surveyed, the coordinate values of each boundary point can be obtained and the determined area of the application site can be obtained.

As described above, when setting the boundary mark of the land, it is necessary to have a highly accurate display function at the boundary point for displaying the boundary with the adjacent land.

For example, as shown in FIG. 7, an arrow mark (3) is added to the upper end surface of the concrete pile sign (1a) as a sign for displaying the land boundary point when it cannot be set over the applied land and the adjacent land that have been conventionally used. ) Is recessed, and the boundary point (2) is displayed at the tip of this arrow (3).

(Problem to be solved by the invention) By the way, in the display structure of the boundary point by the arrow (3), since the arrow (3) is directly recessed in the pile sign (1a), the sharp end of the arrow (3) is formed. Is difficult to form at an acute angle, and when actually used, the tip of the arrow (3) may indicate a boundary point.
It becomes difficult to confirm whether or not the outer peripheral surface of a) is the boundary point, which causes a trouble when the boundary point is determined.

Also, the boundary point must be displayed by one point, but in reality, the boundary point extends to the sky and underground.

However, in the conventional pile marker (1a), the point display by the arrow (3) is ambiguous, and the entire length of the ridge line along the longitudinal direction of the pile marker (1a) has a display function of boundary points. , As shown in Fig. 8, pile markers (1
When a) is driven in an inclined shape, it becomes difficult at which position of the ridge line along the longitudinal direction to display the boundary point, and there is a problem that an error occurs when the boundary point is determined.

The purpose of this invention is to solve the above problems.
The boundary point is clearly displayed as a single point and can be displayed without error in the horizontal and vertical directions, and at the time of surveying the land, it is possible to accurately set the boundary point by attending with the adjacent landowner. To provide a dot display board.

(Means for Solving the Problems) In order to solve the above problems, the present invention is formed in a pyramid shape by a set of three planes each formed in an arrow shape, and the tip collection point of each arrow shape is a land. This is a structure in which the boundary points are displayed.

(Operation) If one arrow-shaped surface is fixed to the upper surface of the pile marker, frame marker, plate marker, and tack marker or directly to the ground, the display part formed by the tip gathering points of each arrow-shaped marker is land. Boundary points will be displayed, and the display area will display one point both in plan and side view, and there will be no error during surveying, and accurate land surveying can be performed.

(Embodiment) An embodiment of the present invention will be described below with reference to FIGS. 1 to 6 of the accompanying drawings.

FIG. 1 shows the basic structure of the boundary point display board (11), which is made of a hard and weather resistant material and has three arrow-shaped surfaces (12), (13), (14). Is formed into a pyramid shape by the set of, and the tip collection point of each arrow shape is the display portion (15) of the land boundary point.

The arrows on the three faces (12), (13), and (14) are
The triangular portions (12a), (13a) and (14a) are formed by projecting linear portions (12b), (13b) and (14b) at the rear ends thereof, and the triangular portions (12a), (13a) and (1
4a) is assembled on three sides to form a triangular pyramid,
Straight parts (12b), (13b) on the bottom surface of the triangular pyramid,
(14b) has a structure in which three angular axes protrude.

Therefore, the boundary point display plate (11) has three arrow-shaped faces (1
2), (13), and (14) are aggregated to form a display portion (15) that becomes one dot at the tip aggregation points of the triangular portions (12b), (13b), and (14b). This display part (15) is a triangle part (12
Since it is a collection point of the ridge lines of a), (13a), and (14a), it can point to one point when viewed from either the plane or the side surface, and can accurately display the land boundary point.

Examples of materials used for forming the boundary point display plate (11) include various metals, ceramics, hard synthetic resins, and the like.
