WEI GUOQING / WANG MENG / GE WEI / YAN BAOFENG / QUAN YOUWEI

The invention discloses an inverted construction method for a high-altitude cantilever steel structure corridor, and relates to the technical field of steel structure construction, and the inverted construction method comprises a supporting platform part, a latticed column supporting part and a steel structure integral hinge. Compared with the prior art, the construction technology has the advantages that compared with independent installation of the steel structure, a lower supporting system is not needed, and the independent installation deflection checking calculation process is omitted; the installation steps are simplified, and the installation precision is effectively guaranteed; in addition, due to the construction method that overall installation is conducted firstly and then splitting is conducted, the elevation and axis construction error of the two independent cantilever structures is zero theoretically, and a good structure size foundation is provided for later interior and exterior decoration; compared with the traditional separate installation, the device is faster, safer and more economical.

本发明公开了一种高空悬挑钢结构连廊逆施工施工方法，本发明涉及钢结构施工技术领域，包括支撑平台部分、格构柱支撑部分以及钢构整装铰接。本发明与现有技术相比的优点在于：本发明施工技术对比单独安装钢构无需下部支撑体系，省去独立安装挠度验算过程；简化安装了步骤，安装精度得到有效保障；另因先整体安装后拆分的施工方法，理论上两独立悬挑结构标高及轴线施工误差为零，为后期内外装修提供良好结构尺寸基础；综述与传统分片独立安装相比更加快捷、安全、经济。
