[0001] The utility model relates to the technical field of building construction, in particular to a self-standing tower ruler support. Background Art

[0002] During the construction process of a building project, it is often necessary to use a tower scale and measuring instruments to measure the elevation. When measuring the elevation, at least two people are required, one responsible for operating the measuring instrument and the other responsible for straightening the tower scale. Moreover, because the tower scale is manually supported, it often tilts, which may lead to measurement errors.

[0003] The traditional measurement method requires at least two people to operate, which wastes manpower. In addition, the tower ruler is manually supported, which often tilts and may cause measurement errors. Therefore, the present invention proposes a self-supporting tower ruler support to solve the above problems. Utility Model Content
