摘要
为解决场地狭小问题,减少超大型塔式起重机吊次,对浙江省全民健身中心B区叠合桁架结构高空原位拼装、正向逐榀提升桁架、正向分层整体提升、逆向分层整体提升、地面叠合拼装然后分层整体提升以及桁架结构是否带上部3层框架提升等6个方案进行对比分析,以确定最优方案,从而提高社会效益与经济效益。
In order to overcome construction difficulties in narrow areas and reduce the lifting operations of super large tower cranes,a comparative analysis was conducted on six schemes for composite truss structures in the zone B of Zhejiang Provincial Mass Fitness Center,namely,high-altitude in-situ assembly,forward lifting of trusses one by one,forward integral lifting layer by layer,reverse integral lifting layer by layer,composite structure assembly on the ground and integral lifting layer by layer,and truss structure lifting with upper 3-layer frames,thereby determining the optimal scheme and improving economic and social benefits.
