Abstract

The invention relates to an internal climbing type tower crane gantry crane auxiliary roof dismantling construction method which mainly comprises a balance arm, a pulling rod, a lifting arm, a winch, a transport trolley, a portal frame, gantry crane column feet, a base fixing bolt set, an internal climbing type tower crane, a hole portal top profile steel cross beam, a power arm rest stand and the like. When the internal climbing type tower crane is disassembled, the portal frame system is installed on the roof to assist in component transportation, and the construction mode is easy to operate and high in construction efficiency. The method mainly comprises the following construction steps: (1) mounting a pulling rod crane; (2) mounting a portal frame; (3) mounting a winch; (4) dismounting a standard knot of the internal climbing tower crane; according to the internal climbing type tower crane gantry crane auxiliary roof dismantling construction method, the internal climbing type tower crane dismantling mode is simple, construction is convenient and fast, and good comprehensive benefits are achieved.

Description

technical field [0001] The invention relates to an auxiliary roof dismantling construction method of an inner-climbing tower crane gantry crane, which is mainly suitable for the inner-climbing tower crane of super high-rise (the center of gravity and the balance arm of the boom can be completely placed on the roof when the inner-climbing tower crane is lowered into place as a whole). tear down. Background technique [0002] With the development of society and the improvement of construction technology, super high-rise commercial and residential buildings have become the darling of the market. The construction of such buildings is characterized by the use of steel-concrete composite structure technology, and the weight of a single component that needs to be transported vertically is large , which poses challenges for vertical transportation in the construction process; ordinary attached tower cranes are generally installed at a height of about 205 meters. The lifting capacit...
