Description

Staff for level measurement

The present invention relates to a level measuring staff, and more particularly, to a horizontal level measuring instrument comprising a horizontal level sensor, a telescope and a sensor, which are raised and lowered at one side of a star, The present invention relates to a leveling instrument for measuring a level of a marker body, which is provided with a marker body, but also has a variable angle as well as an accurate measurement, regardless of an obstacle around the position.

Generally, in order to make a horizontal plane with respect to a construction floor in a construction site or the like, a horizontal level is measured. In this way, a measurement level and a staff are used for horizontal level measurement.

That is, the measurement level unit irradiates the laser in the one direction or the 360 ° direction, and the laser is irradiated in the horizontal direction, thereby becoming the reference for adjusting the horizontal level of the construction floor.

A conventional method of measuring a horizontal level using a measurement level and a staff is as follows. An operator uses a laser beam irradiated in a horizontal direction on a measurement level machine supported by a tripod on a floor, And the distance from the laser beam irradiated from the measurement level device is measured in a state in which the staff is leaned or brought close to the mold for forming the reinforcing bar structure or the wall or the retaining wall. The marker is used to mark the scale line or the leader line on the corresponding reinforcing structure or form, and concrete is laid up to the leader line to complete the construction floor.

As described above, the spacing distance is determined in advance by using the laser and the staff of the measurement level period irradiated in the horizontal direction, and the leader line is displayed on the reinforcing structure or the die of the portion indicating the predetermined spacing distance.

However, since the reinforcing structure or the formwork is complicatedly installed at the construction site, it is difficult to precisely match the laser irradiated from the measurement level device to the scale portion of the staff, and the leader line is correctly displayed on the reinforcing structure or die coming to the measured position There is a problem that it is very difficult to do.

In particular, when a marker is inserted between the reinforcing structures, a leader line is not displayed properly. Therefore, there is a problem that an error occurs between a plurality of leader lines.

In most construction sites, the columns are installed in the area of 20 ~ 30m2, so that there are many reinforcing structures forming the columns and a lot of formworks are installed. Therefore, by these many reinforcing structures and shapes, There is a problem that the laser irradiated from the laser beam collides with the reinforcing steel structure or the mold and is not properly irradiated to the staff at the position to be measured.

This is because the laser beam at the measurement level has a straightness, for example, when there is a reinforcing structure or a mold at the front of the position to be measured, the laser beam comes into contact with the reinforcing structure or the mold.

Such a problem results in that the horizontal level measurement can not be precisely performed, and consequently, even if the concrete is laid, the floor of the construction can not be leveled at all.

In order to display the leader line, the operator must hold the staff member and the other worker must mark the leader line with the marker corresponding to the specific scale of the staff member. Therefore, the worker must move together to display the leader line, And it is necessary to make efforts to display markers between complex reinforcing structures. Therefore, it takes a lot of time and effort to display the leader lines, which causes the construction period to be delayed.

In addition, since the staff has to be raised or lowered according to the measurement position of the horizontal level, since the staff usually has a double or triple structure, the staff having a height of about 2 m There is a problem in that it is not easy to measure the horizontal level.

As a conventional technique, a marker injection type star, which is a registered trademark 10-1151716, has been developed, which is a staple body having a graduated scale, a laser detector installed on the star body to generate a light receiving signal when receiving the laser, And a marker spraying part for spraying a marker solution for displaying a leader line and a marker spraying operation part for operating the marker spraying part, the marker spraying part being installed on the stuf body on the lower side of the detector, A container in which a marker solution of a specific color is attached and detached to / from the jetting section body; a press-feeding section for press-feeding the marker solution in the container; and a marker solution Wherein the press transfer section comprises: a hose extending to the bottom of the container; and a nozzle for sucking the marker solution with the hose A pump for supplying the marker solution to the nozzle, and an operation end for operating the pump, wherein the marker injection operation unit includes a deceleration motor installed in the injection unit body, As shown in Fig.

In this conventional technique, when a laser beam emitted from a laser leveler is received by a laser detector and a corresponding light receiving signal is generated, a marker solution is injected from the marker ejection portion to form a plurality of reinforcing bars, So that the leader line can be accurately displayed.

However, the conventional technique also has a problem that the measurement is not performed properly due to the laser of the measuring level having the straightness and collides with an obstacle such as a reinforcing structure near the measurement position or a formwork or the like, The problem is still not resolved.
