Description

Technical Field

[0001] The utility model relates to an auxiliary device for the construction of building components, in particular to a device for correcting the verticality and angle of a lattice column. Background Art

[0002] In the current subway construction of super-large deep foundation pits, lattice columns are often used as longitudinal beams to support transverse beams and ensure the safety and stability of transverse beams. Generally, the cross section of a lattice column is square. When the installation angle deviation of the lattice column is too large, its cross section will be a parallelogram, making it difficult for the steel bars to pass through the lattice column normally. The lattice column needs to be cut until it matches the steel bars, which greatly reduces the bearing capacity of the lattice column, not only increasing the amount of work, but also prolonging the construction time.

[0003] In some construction sites, due to the limited excavation area and depth, the elevation of the lattice column is quite different from the elevation of the ground surface. After installation, the excess part needs to be cut off, which will cause waste of raw materials and increase construction costs. Therefore, when constructing the column, measures must be taken to control the verticality of the lattice column. Utility Model Content
