超高层建筑核心筒内爬塔吊底部的封闭安全防护平台设计和运用

Design and Application of Sealing Safety Protection Platform at Internal Climbing Tower Crane Bottom in the igh-Rise Building Core Tube

在爬模和内爬式动臂塔吊两个独立系统之间来设计一套安全防护平台,来实现爬模及内爬塔吊的底部封闭。防护平台随内爬塔吊同步攀升,同时可作为内爬式动臂塔吊爬升前后的牛腿拆除、承重钢梁翻运的操作平台。该平台的设计和运用,解决了安装有内爬式动臂塔吊、爬模系统或顶模系统的底部无法封闭的安全防护难题。

A set of safety protection platform between two independent systems of the climbing formwork and the internal climbing movable boom tower crane is designed to have the bottom of the climbing formwork and the internal climbing tower crane sealed properly. The protection platform can rise synchronously with the internal climbing tower crane, and it also can be an operating platform for removing the corbels and for moving the spandrel steel girders. The design and application of such platform have solved the difficulties that the bottom of the internal climbing movable boom tower crane, the climbing formwork system or the jacking formwork system can＇t be properly sealed.
