Description

Technical Field

[0001] The utility model belongs to the technical field of tower crane installation and construction in civil engineering, and particularly relates to a fast-installed adjustable tower crane leg support. Background Art

[0002] At present, in traditional construction technology, when the tower crane is inside the building foundation, the upper and lower layers of the foundation steel bars are usually constructed, and then the steel bars are partially destroyed to install the tower crane legs. In addition, the tower crane legs are fixed by welding the tower crane legs to the foundation steel bars. This process not only affects the foundation steel bars, but also leaves quality risks. In addition, the position and elevation of the tower crane legs will be affected during welding and subsequent concrete pouring, making subsequent adjustments difficult, increasing the difficulty of tower crane installation, and even causing large deviations in the verticality of the tower crane, causing safety accidents. Therefore, the traditional way of fixing the tower crane legs affects the foundation quality, the position and elevation of the legs are difficult to guarantee, the subsequent tower crane installation is difficult, the tower crane verticality deviation is large, and it cannot meet normal use requirements.
