太原湖滨广场主楼采用钢结构外框架-混凝土核心筒结构,高208m,在施工过程中采用2台大型内爬外挂塔式起重机。采用一套循环组合钢结构挂架将塔式起重机悬挂于核心筒的外壁,使塔式起重机随着核心筒的施工进度协调爬升。详细介绍了内爬外挂塔式起重机选型、附着方式、施工原理及挂架的加工制作、质量控制、挂架安装等施工工艺,解决了超高层建筑的垂直运输问题,提高了大型塔式起重机的使用效率,加快了施工进度。
The main building of Taiyuan Hubin Square adopts the steel frame outer frame - concrete core tube structure with a height of 208m. During the construction, two large-scale internal climbing tower cranes are adopted. The tower crane is suspended on the outer wall of the core barrel by a combination of steel frame hangers, so that the tower crane can coordinate and climb along with the construction progress of the core barrel. This paper introduces in detail the selection, attachment method, construction principle, processing and fabrication of pylons, quality control, installation of pylons and other construction techniques to solve the problems of vertical transportation of super high-rise buildings and the improvement of large-scale tower cranes The use of efficiency, speeding up the construction progress.
