Synchronous construction integral steel platform formwork device and construction method

Abstract

The invention discloses a synchronous construction integral steel platform formwork device and construction method, relates to the technical field of building construction, and is used for providing an all-concrete super high-rise building core tube structure and outer frame structure synchronous construction method. The method improves an integral steel platform formwork, in order to adapt to theconstruction of a horizontal structure in a core tube, an original integral bottom steel beam is disconnected, the integral steel platform formwork and peripheral integral lifting scaffold combined construction is adopted, when a super high-rise building with outer frames and core tubes in reinforced concrete structure is constructed, the core tube structure and the outer frame structure synchronously rise, the horizontal structure and a vertical structure are integrally constructed and formed in one step, the structure stress performance is effectively guaranteed, and the construction quality problem and the safety hazards caused by traditional stepped construction are avoided.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to an integral steel platform formwork equipment and a construction method for synchronous construction. Background technique [0002] At present, super high-rise buildings mostly adopt frame core tube structure, which is mainly divided into two types. The first type of core tube is reinforced concrete structure, and the outer frame is steel structure and composite floor slab; the second type of core tube and outer frame columns, beams and slabs are reinforced concrete structure. For the first type of super high-rise building, the construction is usually divided into three steps. The vertical structure of the core tube is first, followed by the horizontal structure of the core tube, and finally the outer frame steel structure and floor slab. [0003] However, if the above-mentioned process is adopted for the second type of super high-rise building in which both the ou...

Problems solved by technology

[0003] However, if the above-mentioned process is adopted for the second type of super high-rise building in which both the outer frame and the core tube are reinforced concrete structures, the horizontal structure of the outer frame and the horizontal structural steel bars in the core tube must all be disconnected at the same section, and the subsequent construction process is complicated; During the construction, there are vertical and vertical cross operations, and there are hidden dangers in the construction quality and construction safety; the vertical structure and the horizontal structure cannot be constructed at one time, which has a great impact on the mechanical performance of the structure
