Description

[0001] The utility model relates to the technical field of structural columns, in particular to a verticality control device for a peripheral cantilevered structural column. Background Art

[0002] At present, in the construction of many office buildings, more peripheral cantilevered structural columns are involved. Cantilevered structural columns are mainly used to strengthen the structure of the surrounding wall under the cantilever beam and restrain deformation.

[0003] During the construction process of cantilevered structural columns, their verticality needs to be controlled. The traditional method of controlling the verticality of structural columns is generally to use steel wires or laser instruments in the building. This control method has large errors on both sides, and it is not easy to hang the wire on the outermost side. As a result, the verticality deviation of the outer structural columns is large, not straight, and the appearance is poor, which seriously affects the construction effect of the facade.
