The invention discloses an aerial in-situ underpinning platform structure of a super high-rise construction elevator and a construction method of the aerial in-situ underpinning platform structure. The aerial in-situ underpinning platform structure comprises an aerial foundation platform, a standard knot stress conversion mechanism, a lower hanging scaffold platform and a pressure slow release mechanism. The construction method comprises the steps that an air foundation platform is arranged on a core tube wall of a construction elevator hole, a standard knot stress conversion mechanism and a lower hanging scaffold platform are constructed on the air foundation platform, and a pressure slow release mechanism is constructed on a lower standard knot; after upward thrust is applied to the foundation beam through a vertical oil cylinder of the pressure slow-release mechanism, part of the lower standard knots are removed, the vertical oil cylinder retracts to slowly apply the weight of the remaining standard knots to the foundation beam of the aerial foundation platform, and the pressure slow-release mechanism and the remaining lower standard knots are removed. And a third supporting beam is arranged below the upper standard knot to transfer the weight of the upper standard knot to the aerial foundation platform, and the lower hanging scaffold platform is dismounted. The installation efficiency can be improved, and the construction period can be shortened.
本发明公开一种超高层施工电梯空中原位托换平台结构及其施工方法,该平台结构包括空中基础平台、标准节受力转换机构、下挂脚手架平台和压力缓释机构;该施工方法包括将空中基础平台设置在施工电梯洞口的核心筒墙体上,在空中基础平台上施工标准节受力转换机构和下挂脚手架平台,在下部标准节上施工压力缓释机构,通过压力缓释机构的竖向油缸对基础梁施加向上的推力之后拆除部分下部标准节,回缩竖向油缸缓慢地将剩余标准节的重量施加到空中基础平台的基础梁上,拆除压力缓释机构及剩余的下部标准节,在上部标准节下方设置第三支撑梁将上部标准节的重量转换到空中基础平台上,拆除下挂脚手架平台。本发明能够提高安装效率、缩短施工周期。
