摘　　要：在华南地区某超高层建筑中,核心筒外墙和电梯井采用液压爬模施工,对核心筒内水平结构进行同步施工,外框钢结构滞后施工。该项目平立面变化较大,存在平面结构内收与立面墙厚收缩量较大的特点,且层高较高、变化较大,同时,第52,53层为伸臂桁架层,相关部位需预留牛腿。通过液压爬模与动臂塔式起重机、液压爬模与混凝土布料机配合施工,利用上架体抗风拉结、变截面爬升、爬模拆改等措施,采用设置辅助墙体、预埋爬模点位、控制作业荷载、安置混凝土喷淋系统等方法,进行核心筒液压爬模施工。设置防护翻板、翻折平台,以保证核心筒液压爬模施工安全。In a super high-rise building in South China, the outer wall of the core tube and the elevator shaft were constructed by hydraulic climbing formwork. The horizontal structure in the core tube was constructed synchronously, and the steel structure of the outer frame lagged behind. The engineering plane and facade changed greatly, with such characteristics as plane structure adduction and large shrinkage of facade wall thickness. The layer height was not only high, but also varied greatly. At the same time, the 52nd and 53rd layers were the outrigger truss layer, and corbels needed to be reserved at the relevant parts. Through the cooperation of hydraulic climbing formwork and boom tower crane, hydraulic climbing formwork and concrete distributor, the hydraulic climbing formwork construction of core tube was carried out by using the measures of wind-proof tie knot of upper frame, variable cross-section climbing, climbing formwork disassembly and modification, setting auxiliary wall, pre-embedded climbing formwork point, controlling working load and placing concrete spraying system, etc. Protective flaps and folding platforms were set up to ensure the construction safety of the core tube hydraulic climbing formwork.
