［摘要］南京金鷹天地廣場(chǎng)的空中連接體位于200m左右的高空，共有6層，最大跨度超過(guò)70m。連接體的底部為雙向正交的轉(zhuǎn)換桁架層，采用在裙房屋面拼裝完成后整體提升的施工方案?；谠摲桨?，對(duì)拼裝階段的桁架與裙房相關(guān)結(jié)構(gòu)構(gòu)件進(jìn)行分析校核，確定了合理的拼裝支撐方案；在轉(zhuǎn)換桁架層的整體提升與安裝過(guò)程中，桁架層處于二階段受力的狀態(tài)，對(duì)桁架層進(jìn)行了全過(guò)程施工模擬，并對(duì)空中連接體的設(shè)計(jì)要點(diǎn)進(jìn)行了總結(jié)；空中連接體整體提升時(shí)，三棟塔樓處于相對(duì)獨(dú)立的狀態(tài)，與最終使用工況有較大的差別；研究了連接體提升過(guò)程中主塔樓的變形與承載力，確保了主體結(jié)構(gòu)的安全。

Abstract:The sky connected lobby of Nanjing Golden Eagle Tiandi Plaza has six stories, with a maximum span of more than 70 meters and is connected at an altitude of about 200m. The bottom of the connected body is a two-way orthogonal transfer truss layer, which adopts the construction scheme of integral lifting after the assembly of the skirt floor. Based on this scheme, the relevant structural components of the truss and skirt building in the assembly stage were analyzed and checked, and the reasonable assembly support scheme was determined. During the whole lifting and installation of the transfer truss layer, the truss layer was in the state of two-stage stress, the whole construction process of the truss layer was simulated, and the design key points of the sky connected body were summarized. The three main towers were relatively independent when they were lifted, which was quite different from the final service conditions. The deformation and bearing capacity of the main tower during the lifted process of the connected body were studied, which ensured the safety of the main structure.

Keywords:super high-rise building; connected structure; sky connected lobby; integral lifting; construction simulation
