Super-heavy overhanging suspension member supporting system of super high-rise residential building conversion layer and construction method of super-heavy overhanging suspension member supporting system

Abstract

The invention discloses a super-heavy overhanging suspension member supporting system of a super high-rise residential building conversion layer and a construction method of the super-heavy overhanging suspension member supporting system. According to the method, a reinforced load-bearing steel pipe column, a steel box beam bracket, a bailey frame, an I-beam distribution beam and a dense type steel pipe fastener type supporting frame constitute the suspension member supporting system. The member load is evenly transmitted to a cantilevered steel platform through the dense type steel pipe fastener type supporting frame, and the size of the steel platform can be flexibly designed to meet the requirements according to the actual load, span and overhanging length on site. Fewer materials are used and can be used in a recycling mode, no requirement for the bearing capacity of a lower horizontal structure exists, and the impact on construction of surrounding podium buildings and undergroundstructure areas is reduced. The construction process is safe and reliable, green and environmentally friendly, the popularization rate is high, and the super-heavy external overhanging suspension member supporting system is very suitable for construction tasks similar to super-heavy external overhanging suspension members.

Description

technical field [0001] The invention relates to a support system and a construction method for a super-heavy overhanging suspended component of a transition floor of a super high-rise residence, belonging to the technical field of building construction. Background technique [0002] With the rapid development of the national economy and the advancement of design-construction technology, my country's urban construction is also advancing by leaps and bounds. Various super high-rise and large-scale complex projects continue to innovate structural types and refresh building heights. Among them, the super high-rise residential complex with frame-supported shear wall adopts a frame structure at the lower part, and the upper part needs to be converted into a shear wall structure at a high level; and the structural self-weight corresponding to the height of the super-high building and the requirements for the layout of the lower part often easily lead to the need for conversion floor...

AI Technical Summary

Problems solved by technology

Among them, the super high-rise residential complex with frame-supported shear wall adopts a frame structure at the lower part, and the upper part needs to be converted into a shear wall structure at a high level; and the structural self-weight corresponding to the height of the super-high building and the requirements for the layout of the lower part often easily lead to the need for conversion floors. In the case of oversized, overweight and complex structures and overhangs, the conventional floor-to-ceiling formwork (the structure occupies a large area, has a complex structure, and is very high) can no longer meet the progress, safety and economic requirements of similar project construction tasks.
