[0002] During the house construction process, it is usually necessary to measure whether the ground is level. In order to ensure the construction quality of the building, a leveling device is required to check the installation and construction of the building in many construction links. During the house construction process, it is necessary to measure the flatness of the ground and control the flatness of the ground within a reasonable range to ensure the quality of the building.

[0003] Relevant patents include a building construction leveling device with application number 202121104629.2, which includes a base, and rubber supports are fixedly connected at the four corners of the lower surface of the base. The ground is leveled by moving the measuring rod upward. Since multiple measuring rods are set for ground leveling, the operator's perspective is affected. When the upward movement distance of multiple measuring rods is close, it is difficult for the operator to judge whether the ground is flat with the naked eye, and the uneven position of the ground cannot be marked intuitively, accurately and quickly, which has great resistance to the leveling of building construction, and the height of the undulation and the degree of depression of the uneven ground cannot be specifically measured during measurement.

[0004] Therefore, in response to the above problems, we propose a leveling device for building construction. Utility Model Content
