多变立面超高层折叠式施工升降平台爬升技术

FOLDABLE LIFTING PLATFORM CLIMBING TECHNIQUE FOR CONSTRUCTION OF SUPER-HIGH BUILDING WITH IRREGULAR FACADE

深圳太子广场工程外防护采用施工升降平台(折叠式升降脚手架),架体高19.5m。爬升过程中,须适应建筑立面4次变化,且要爬过桁架层局部外伸托座、核心筒墙身截面尺寸反复变化和核心筒处墙身平面布置变化等部位,对此采取相应技术措施,保证了升降平台及时到位,满足了防护封闭要求和超高层施工安全。

Lifting platform (foldable lifting scaffold) was adopted in external protection layer construction of Shenzhen Prince Plaza and the scaffold is 19.5m high. It must be considered that the building facade changes for four times during climbing-up of the platform, which has to cross over the local cantilever base of the truss floor and positions where the cross section and plane layout of core tube wall changes. Therefore, relevant technical measures were adopted to guarantee timely and correct operation of the lifting platform and to satisfy the requirements for protection closing and super-high building construction safety.
