Super high-rise building inhaul cable type flexible steel platform formwork and lifting method

Abstract

The invention discloses a super high-rise building inhaul cable type flexible steel platform formwork and a lifting method. The steel platform formwork comprises a steel platform, outward extending corbels of the steel platform, upright post supporting structures, upright post corbels, a connecting truss, jacking oil cylinders, oil cylinder corbels, a main cable and a plurality of adjustable inhaul cables; and the steel platform is supported on an outer side wall body of a core barrel shear wall through the outward extending corbels of the steel platform, the upright post support structures are supported on an inner side wall body of the core barrel shear wall through the upright post corbels at the side parts, the jacking oil cylinders are arranged at the bottoms of the upright post support structures and are supported on the inner side wall body of the core barrel shear wall through the oil cylinder corbels, the two ends of the main cable are respectively connected with the tops ofthe two upright post support structures, and the plurality of adjustable inhaul cables are used for lifting the steel platform. According to the steel platform formwork and the lifting method, a mainclimbing member of the steel platform is converted into a tension member from a compression member, the compression support is separated from the climbing member, and the limitation of a climbing height per time is not needed to be considered.

Description

technical field [0001] The invention relates to a cable-type flexible steel platform formwork for super high-rise buildings and a lifting method, belonging to the technical field of super high-rise steel platform formwork. Background technique [0002] Steel platform formwork equipment is one of the construction equipment commonly used in super high-rise building structures in recent years. The existing steel platform formwork equipment is divided into two types: jacking type and lifting type, both of which use the overall steel frame, platform slab, scaffolding system, etc. to provide a closed construction work surface, making full use of the characteristics of the strong bearing capacity of the steel structure ; Use the hydraulic cylinder to provide the driving force to make the formwork equipment climb up along the core tube of the super high-rise building. The steel bars required for the construction of the core tube can be stacked on the top working plane of the steel ...

AI Technical Summary

Problems solved by technology

When the overall load is greater, the requirements for corbels or load-bearing components are higher, and the components are changed from force limitation to deformation limitation, and the rigidity requires the section of the component to increase continuously, making it difficult for the steel platform formwork equipment to withstand excessive loads

At the same time, because the internal force of the corbel or load-bearing members is difficult to effectively measure, it is difficult to effectively evaluate the safety during the operation process and climbing process

[0005] At the same time, whether it is the lifting type or the jacking type, there is a problem of lifting the auxiliary member column under pressure and instability, which will limit the single climbing height of the steel platform formwork equipment, making each climbing a small distance , it is necessary to re-switch the force system and check the synchronization, so that the climbing speed and climbing efficiency are greatly reduced
