北京庄胜广场中央楼空腹桁架结构施工支撑

SHORING MEMBERS FOR CONSTRUCTION OF VIERENDEER TRUSS STRUCTURES OF THE BEIJING ZHUANGSHENG SQUARE CENTRAL BUILDING PROJECT

北京庄胜广场中央楼24m跨多层空腹桁架是该工程结构施工的重点控制部位 ,其关键是保证空腹桁架梁的挠度值在设计允许范围内。为此采取措施利用脚手钢管支设荷载近6万kN的空腹桁架施工支撑 ,保证了支撑抗侧移的性能。

The multi-storey 24 m span vierendeel trusses are the key structures to control due operations of the Beijing Zhuangsheng Square Central Building.Therefore,all deflections of these vierendeel trusses must be strictly controlled within their design' s allowable limit.To achieve these goals,measures of adopting steel pipe scaffoldings for constructions of 60 000 kN vierendeer trusses shoring members,have been proved successful to control their lateral displacements.
