Horizontal pushing device for wall tilt laser test

Abstract

The invention discloses a horizontal pushing device for a wall tilt laser test. The horizontal pushing device comprises a first screw structure on a platform, the first screw structure comprises a base on the platform, a screw passing through the base and rotatingly fitting to the base, a guide rod arranged parallel to the screw and slidably fitting to the base and a guide block connected to the screw through threads and slidably fitting to the guide rod. The guide rod is linked to a connection rod. The connection rod is located below the platform. Laser emitted by a laser marking instrument is irradiated on the bottom surface of the connection rod. The horizontal pushing device has a reasonable structure and can accurately measure the tilt of the wall of the platform.

Description

technical field [0001] The invention relates to a wall inclination testing technology, in particular to a horizontal moving device for wall inclination laser testing. Background technique [0002] When testing the seismic strength of buildings (especially buildings in old building areas), the staff will test the wall inclination of the building, that is, the verticality of the wall. [0003] At present, a simple detection method combined with the Figure 5 As shown, it is that the wall 1 is built on the ground. During the detection process, the staff can place the laser marking instrument 3 on the side of the wall 1 on the ground, and the laser marking instrument 3 can emit vertically upwards. A laser beam, and then the staff places a transparent glass plate 9 on the upper part of the wall 1 (it can be the second floor), the laser passes through the glass plate 9, and the distance from the upper part to the laser point is measured by a ruler as L'; the ruler is used in advan...

Problems solved by technology

[0004] However, at present, many buildings have a platform on the second floor. The position of the platform prevents the staff from extending a glass plate 9 directly on the second floor. It is difficult for the staff to measure the distance between the laser point at the bottom of the platform and the wall 1.

In addition, because the width of the platform is relatively large, it is difficult to ensure the level of the ruler during the measurement process by protruding a glass plate 9 directly on one side of the platform, especially when the inclination of the wall 1 is small, it is difficult to obtain better detection. result
