超高层外爬塔式起重机高空平移施工技术

Construction Technology of Tower Crane High Translational Outside Super-tall Climbing

以深圳华润总部大厦"春笋"实际工程为依托,结合该项目施工过程中塔式起重机及支撑架在爬升过程中因墙体变化,避免塔式起重机中心距核心筒墙体间距过大带来的安全隐患,经过塔机高空平移技术,解决核心筒墙体收缩变化较大外爬塔机安全顺利爬升。

It was based on the actual project of China resources headquarters building named ＂Chunsun＂ in Shenzhen,combined with the changes of thickness of the wall during the project construction process by climbing of tower crane and support frame,avoided safety loophole brought by oversize space between tower crane center and core tube wall,with a tower crane high translation technology,confirmed climbing tower crane climbed smoothly by solving the changes of core tube wall shrinkage.
