Abstract

(57) [Summary] [Purpose] The objective is to provide a survey point marking that solves the problems inherent in conventional survey point markings. [Structure] A circular or polygonal transparent plate having a through hole having a rivet seat at the center, a circular or polygonal opaque plate having a through hole at the center, and being attached to and detached from the transparent plate and the through hole of the opaque plate. A surveying point explicit sign consisting of flexible tacks.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an explicit sign of a survey point at arbitrary coordinates.

[0002]

[Prior art]

 Conventionally, the survey points of public coordinates measured by the Geographical Survey Institute are called reference points or standard points, and for example, surveying tacks proposed in Japanese Utility Model Publication No. 3-30821 are used to display them. . In addition to the survey by the Geographic Survey Institute, there are surveys for construction performed by ordinary surveyors. This survey is usually called arbitrary coordinates with respect to the public coordinates mentioned above. The surveyor puts a sign on the surveying point which is the base point of the construction at the time of surveying, the contractor of the construction specifies the construction contents based on the surveying point which is the base point, and the construction person uses the surveying point which is the base point. According to the signs and specifications of, confirm the details of the construction, create a quotation, receive the construction order, and start construction. For this reason, signs with arbitrary coordinates are often used by construction personnel about six months after the surveyor's survey. On the other hand, there are innumerable other construction-related sign points around the sign. Therefore, from the survey to the start of construction, the sign of the survey point, which is the base point of the construction, is maintained in a healthy state, and at the same time, the surveyed surveyor and the survey date, survey point name, survey point symbol, reference survey It is desired that the constant distance and the like be clearly shown. This is because it facilitates the confirmation of the survey point markings from the start of construction order consideration to the start of construction, and facilitates the processing of the above-mentioned various tasks related to construction. However, at present, there are colored or engraved opaque signs that are maintained in a healthy state until the start of construction, but there is no sign that clearly shows the above items.

[0003]

[Problems to be solved by the device]

 An object of the present invention is to provide a survey point explicit marker that solves the problems inherent in the conventional survey point markers described above.

[0004]

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention has a circular or polygonal transparent plate having a through hole having a rivet seat at the center, and a circular plate having a through hole at the center. A polygonal opaque plate, a transparent point and a through-hole of the opaque plate, detachable studs are used as the means for indicating the survey point,

On the surface of the opaque plate, a design such as a flower pattern, a company emblem, a trademark, etc., which does not obstruct the description of various matters, is printed, or is engraved or provided as a relief pattern. This is the second means.

[0006]

[Action]

 Since the present invention uses the above-mentioned means, the confirmation of the required survey points from the inquiry of the construction work to the start of construction can be confirmed promptly and accurately after the arbitrary survey, and the construction progress becomes smooth. The surveyor is clarified for each surveying point, the image of the surveyor with excellent surveying technology is improved, and it contributes to the improvement of the surveyor's technology.

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. 1 is a side sectional view of the present invention, FIG. 2 is a plan view, FIG. 3 (a) is a plan view of an example of a transparent sign, (b) is a plan view of an example of an opaque plate, and FIG. 4 (a) is a tack. A side view and (b) are plan views.

1 to 4, 1 is a transparent sign, 2 is a stud, 3 is a through hole of the transparent sign 1, 4 is a tack, 5 is an opaque plate, and 6 is a through hole of the opaque plate 5. The transparent sign 1 and the opaque plate 5 of this example are circular, but the present invention is not limited to the circular shape of this example, and polygonal shapes such as triangles to octagons can be used in paving places, mountains, fields, etc. Furthermore, as a sign, the optimum shape can be selected and used according to the usage conditions such as direct driving at the pavement site, driving at the apex of the pile in the mountainous area or the open field. Further, if the tack head is the same as or higher than the height of the tack seat 2 by 1 to 2 mm, the breakage of the transparent sign 1 at the completion of the driving is reduced.

The material of the transparent sign 1 used in the present invention is a synthetic resin having transparency, pressure resistance and weather resistance, and it is easy to economically manufacture a large amount of the sign, and it is easy to guarantee the material quality of the product. Therefore, it is desirable. Further, as the opaque sign 5, a corrosion-resistant metal plate (aluminum plate, brass plate, stainless plate, etc.), a synthetic resin, or the like can be used in which the above-mentioned required items can be described by a normal oil-based ink. The opaque sign 5 has a design 7 which does not hinder the description of the above-mentioned matters, for example, a flower pattern shown in FIG. 3B, a printing or engraving of a company emblem, a trademark, etc. It is preferable to apply it because it will bring new comfort, fun and moisture together with the confirmation work of the described items.

To use the product of the present invention, the transparent sign 1 is placed on the opaque plate 5 on which the required items are described, the rivets 4 are put through the through holes 3 and 6 of both, and the rivets 4 are set. The lower part of the head of the tack 4 is pressed against the tack seat 2 for completion.

[0011]

[Effect of device]

 Since the present invention uses the above-mentioned means to exert the above-mentioned unique action, it is difficult and inaccurate for the construction planner and construction order examiner to confirm, as with the signs of arbitrary coordinates that have been widely used from the past. Therefore, the large amount of labor and time that has been spent in the past is unnecessary, and the progress of construction is extremely smooth.This has a great effect on this kind of field and has a ripple effect on related fields. large.
