摘　　要：以北仑霞浦通山未来社区通山之眼钢桁架连廊为案例,介绍一种组合式高空钢桁架连廊吊装施工工艺——“高空悬拼+整体提升”施工工艺进行大跨度空间异形桁架式钢结构连廊的吊装。该工艺保证了桁架结构的快速、精准安装,同时在施工场地允许的条件下,最大程度地降低高空作业量,有效保证了安装工期,提高了施工的安全性、可靠性,可为今后类似异形钢桁架空中连廊的安装施工提供一定的借鉴。Using the Tongshan Eye steel truss corridor in Tongshan Future Community,Xiapu,Beilun as an example,a combined hoisting technique:"high-altitude cantilever assembly+integral lifting"—is introduced for hoisting largespan,special-shaped truss steel structure corridors.This method ensures the rapid and precise installation of the truss structure while minimizing high-altitude work under the permitted conditions of the construction site.It effectively ensures the installation schedule and enhances the safety and reliability of construction,providing a reference for similar installations of special-shaped steel truss corridors in the future.
