Problems solved by technology

[0002] In the construction process of the construction site, it is often necessary to carry out level measurement, and in the process of level measurement, the error of level measurement is often caused by environmental factors or installation factors, and now the level calibration often uses a heavy hammer, but the heavy hammer It often takes up a lot of space in the vertical direction, which is not conducive to the measurement of surface level. In addition, it takes a long time to calibrate, is greatly affected by wind or other factors, and has a large volume

Embodiment 1

[0029] Such as figure 1 , 2 As shown, the present invention discloses a laser level measuring device for building construction, comprising a pipe body 2 blocked on both sides, a transparent liquid is housed in the pipe body 2, a reflector is arranged below the liquid surface of the liquid, and the pipe body One end of 2 is provided with a laser 1, and the other end is provided with a mapping plate 4, and the laser is projected onto the mapping plate 4 after at least one total reflection of the liquid surface.

[0030] A mounting frame 9 is arranged below the pipe body 2, and an alignment measuring mechanism is respectively arranged on both sides of the mounting frame 9, and the alignment measuring mechanism is used for the alignment of the point to be measured and the measurement of the distance between the pipe body 2 and the point to be measured .

[0031] The alignment measurement mechanism includes a slide frame 5, a lifter 6 and a strut 8. The slide frame 5 is slidably ...

Embodiment 2

[0036] In Embodiment 1, the method for the controller to control the laser 1:

[0037] Step 1: Place the tube body 2 horizontally, turn on the laser 1, and the laser is projected onto the mapping board 4 after being totally reflected by the liquid surface, so that the optical sensor on the mapping board 4 sends a signal to the controller;

[0038] Step 2: When the optical sensor sending the signal to the controller is not the optical sensor at the designated position, the controller controls the displacement mechanism to rotate the laser 1 according to the relative position of the optical sensor sending the signal and the optical sensor at the designated position.

[0039] Through the control method of the laser 1, horizontal calibration can be accurately realized, thereby improving measurement accuracy and stability, and improving calibration stability and calibration speed.

Embodiment 3

[0041] Based on the laser level measuring device for building construction in embodiment 1, the method for measuring the level of the tower base for tower crane installation is:

[0042] Step 1: Adjust the struts 8 on both sides of the installation frame 9 to the same height, adjust the position of the sliding frame, make the lower end of the strut 8 align with the installation point of the tower base, adjust the height of the auxiliary strut 7, and make the cross bar 10 horizontal ;

[0043] Step 2: Gradually adjust the height of the auxiliary support rod 7 and adjust the height of the support rod 8 through the lifter 6, so that the laser light emitted by the laser 1 is totally reflected by the liquid surface and then points to the designated position of the mapping plate 4;

[0044] Step 3: According to the height difference of the struts 8 on both sides of the installation frame 9, judge whether the tower base is level and its deflection amount.

[0045] This method is suita...

Abstract

The invention relates to the field of building construction, and particularly relates to a laser leveling device for building construction, which is suitable for leveling a tower foundation when a tower crane is installed. The laser leveling device comprises a pipe body, wherein both sides of the pipe body are blocked, the pipe body is filled with transparent liquid, a reflecting mirror can be arranged below the liquid level of the liquid, a laser is arranged on one end of the pipe body, a mapping plate is arranged on the other end of the pipe body, and laser is projected to the mapping plate after total reflection of the liquid level at least once. According to the structure, the laser is projected by utilizing a total reflection principle of water or other transparent liquid, the laser is projected to a designated position in a leveling condition, and the projection position changes due to the position change of the liquid level in a non-leveling condition; the structure has the advantage of accuracy in measurement, the levelness can be quickly and accurately measured, and the levelness is accurately reflected by utilizing the flowability of the liquid under the action of gravity.
