{CONTROL POINT FOR SURVEYING}

The present invention relates to an urban survey reference point marking that can support a surveying pole vertically.

In general, the measurement reference point is a point indicating the location and elevation set up by basic and public surveying based on the survey method, and distinguishes between the national reference point managed by the state and the public reference point managed by the public surveying organization.

The urban survey reference point is one of the public reference points with the accuracy of the national reference point and aimed at ease of use, accuracy, and ease of management by installing it on the flat ground in the city. It is a space for city facilities such as roads, waterworks, It is the basis of the Urban Information System (UIS) for efficient construction and management of information.

On the other hand, the measurement pole is installed on the reference zero point of the urban survey reference point marking at the time of measurement using the urban survey reference point, and measurement equipment such as a GPS equipment or a reflecting mirror is mounted on the measurement pole.

However, conventionally, since the measurement pole is set perpendicularly to the reference zero point of the land survey reference point by using the ordinary tripod, there is a problem that the operation by the installation of the survey pole is cumbersome. Since this operation is not an easy task for beginners, There is a problem in that the working time is long.

When the measuring pawl P is lifted to remove the measuring pole P, the compressed elastic spring 128 is restored and the zero point indicating member 110 is returned. When the zero point indicating member 110 is returned, The display member 110 is spaced apart from the lower ends of the operating bars 132 and the compressed torsion spring 144 is restored to rotate the operating bars 132 around the first hinge pin 134 to return. Whereby the holding jaws 146 connected to the upper ends of the operating bars 132 release the gripping of the measuring pole P. [

On the other hand, the casing member 150 is provided in a vertically cylindrical shape with its top and bottom open as shown.

The casing member 150 defines therein a zero point indicating member 110 and a measuring pole holding member 120. A zero point indicating member 110 is provided on the inner circumferential surface of the casing member 150, An annular flange 152 is integrally formed to expose a reference zero 114 formed on the surface portion 112 of the zero point indicating member 110 while not being separated.

A female screw 154 is formed on the inner circumferential surface of the casing member 150 which is connected to the lower end of the casing member 150 and is fastened to the male screw 124 formed on the outer circumferential surface of the bottom plate 122.

That is, the zero point indicating member 110 and the measurement pole support member 120 are inserted into the casing member 150 through the open lower portion of the casing member 150 and the bottom plate 122 Is fixed to the female screw 154 so that the zero point indicating member 110 and the metering pole supporting member 120 are confined within the casing member 150.

The metrology reference point marking tool 100 according to the present invention thus formed is fixed to the ground so that the flange 152 of the casing member 150 and the reference zero point 114 of the zero point indicating member 110 are exposed to the outside of the paper surface. .

Hereinafter, the use state of the metric reference point marking tool 100 according to the present invention formed as described above will be briefly described.

In order to support the metering pawl P on the metrology reference point marking pawl 100 according to the present invention, first, the lower end of the metering pawl P is brought to the zero point 114, which is aligned with the reference zero point 114 exposed to the outside of the paper, Thereby pressing member 110.

As described above, when the zero point indicating member 110 is pressed by the measuring pawl P, the zero point indicating member 110 compresses the elastic spring 128 and pushes the bite jaws 146, And is guided to the inner side of the connecting portion 126 while descending along the inside of the holding jaws 146.

When the lower ends of the operating bars 132 are pressed, the holding jaws 146 are moved in the direction of the measurement pole 132. [ (P) side to support the measurement pole (P) while grasping the measurement pole (P).

That is, when the rear surface portion 116 of the zero point indicating member 110 presses the lower end side of the operating bars 132, the operating bars 132 rotate about the first hinge pin 134, The upper ends of the operating bars 132 are rotated toward the measuring paw P while compressing the torsion springs 144 as the first and second hinge pins 132 rotate about the first hinge pin 134, The inner side surfaces of the holding jaws 146 are brought into close contact with the measuring pawls P so as to grip the measuring pawls P. As a result, And is vertically supported on the urban survey reference point marking port 100.

Here, it is preferable that the zero point indicating member 110 can be pressed by the weight of the measuring pole P alone.

On the other hand, when the measuring pawl P is shaken to the left and right to remove the measuring pole P, the holding by the holding jaws 146 is released, and when the measuring pole P is slightly lifted under such condition, The elastic spring 128 is restored by the restoring force and the zero point indicating member 110 is separated from the lower end side of the operation bars 132. When the zero point indicating member 110 is separated from the lower end side of the operation bars 132 The upper ends of the operating bars 132 and the bouncing jaws 146 are returned to the outer peripheral surface side of the connecting portion 126 by the restoring force of the compressed torsion springs 144, P).

As the upper end of the actuating bars 132 and the retaining jaws 146 are returned, the zero point indicating member 110 ascends along the inner side of the retaining jaws 146 constituting a set due to the restoring force of the elastic spring 128 And is returned to the upper side of the holding jets 146. [

The metrology reference point marking unit 100 according to the present invention thus formed allows the surveying pole P to be installed vertically on the metering reference mark marking spot 100 rather than an experienced operator, This can significantly reduce time.

The metrology reference point marking 100 capable of supporting the surveying pole as described above is not limited to the construction and the manner of operation of the embodiments described above.
