Description

Measuring ruler for building

Technical Field

Background

After the construction of the building engineering structure is finished, in order to match the structure to check and accept, an elevation datum line must be set so as to check and accept conveniently. In the building finishing and equipment installation stage, in order to ensure the correct positions of relevant parts and equipment inside the building, elevation control reference lines are also set, and the elevation reference lines or the elevation control reference lines are usually implemented by setting a '50 line'. The so-called "50 lines" are lines of bounces 500 mm above the level of the building floor.

At present, the determination of the 50 lines of the building construction is mainly realized by the cooperation of a common tower ruler and a level gauge. However, the method needs to continuously move the sliding staff and then calculate, which is time-consuming and labor-consuming, and a method of determining the 50-line point position by using a laser beam also appears at the present stage.

However, since 50 lines need to be marked on the inner surface and the outer surface of the wall body, when the device is moved to the outer surface of the wall body after 50 line points on the inner surface of the wall body are marked, the 50 lines on the inner surface of the wall body cannot be referred to due to the difference in height of the foundation outside the inner wall of the wall body, so that the 50 lines drawn on the outer wall surface and the 50 lines on the inner wall surface have deviation.
