The method of climbing the tower crane during the construction process

Abstract

The invention discloses a method for climbing of a tower crane in the construction process. According to the method, arrangement manners of permanent attachment and temporary attachment are used, so that the influence of a flat arm type tower crane on the progress of a core cylinder in the construction process can be solved, thereby improving the construction efficiency. Since the temporary attachment can be reused, the cost of a measure for climbing of the tower crane is reduced and the cost is saved; meanwhile, the time for climbing in each time is short; the influence on the construction of steel structures and concrete is reduced to the lowest; meanwhile, the disassembly process of the tower crane is simplified, and thus the time is saved.

Description

technical field [0001] The invention relates to the construction field, in particular to a method for climbing a tower crane during construction. Background technique [0002] At present, super high-rises are springing up like mushrooms after rain in China. The construction of super high-rises generally adopts the jib crane to be arranged inside the core tube (climbing inside) or hanged on the shear wall of the core tube (climbing outside). Carry out a calculation review on the cylinder to determine whether it needs to be reinforced. For some super high-rise buildings, the single weight of the steel components is relatively light, so there is no need to use super-large lifting equipment. At the same time, the shear wall of the core tube is thin, and the location of the elevator shaft is small, so it is impossible to arrange lifting machinery in the core tube. However, if the tower crane equipment is arranged after taking measures to reinforce it with steel, the gain outweig...

AI Technical Summary

Problems solved by technology

[0003] Most super high-rise buildings adopt the structural system of inner core tube shear wall and outer steel frame. In general, the construction of the core tube is ahead of the construction of the peripheral steel structure in the construction process. Usually, the core tube is tens of meters higher than the peripheral steel structure. The boom tower crane cannot swing up and down like the moving boom tower crane. When the core tube is constructed to the height of the boom mark, the climbing wall of the tower crane has not yet reached the installation condition, that is, the height of the climbing wall of the tower crane has not been increased accordingly. It will inevitably affect the construction of the entire core tube, which will cause the entire project to fall into an endless loop and affect the overall progress.
