| 摘 要： | 深圳京基金融中心伸臂桁架安装时与核心筒顶模相冲突,采用"散件吊装、高空组拼、逐层分次作业"的工艺,有效地解决了伸臂桁架安装、核心筒顶模系统顶升和混凝土施工的协调同步问题,并创新性地提出"双机抬吊、交替更换吊点、旋转移位"的吊装工艺,该工艺新颖实用,具有一定的推广价值.

| Abstract: | For the project of Shenzhen Kingkey Financial Center, the installation of cantilever truss conflicted with core-tube jacking formwork. The synchronous coordination of cantilever truss installation, core-tube formwork jacking and the concrete construction had been solved effectively by using the process of lifting components,assembling them overhead and working layer-by-layer.In addition,it was put forward the lifting technique of two-tower crane lift, lifting points change in turn, rotation and shift, which... |
