摘要
杭州望朝中心建筑总高度为280m,塔楼主体结构施工采用2台大型内爬外挂式动臂塔式起重机。由于塔式起重机支座节点处荷载较大,针对结构局部区域强度或刚度不足位置进行验算,对塔式起重机支座进行分类,采取局部钢筋加强增加撑材和两者结合的加固方案,解决了爬升或起重机附着处结构加固问题。
The total height of Hangzhou Wangchao Center is 280m.The main structure of the tower is constructed with two large-scale internally climbing and externally mounted luffing tower cranes.Due to the large load at the node of the tower crane support,check calculations for the location of the local area of the structure where the strength or stiffness is insufficient,classify the tower crane support,and adopt the reinforcement plan of local steel reinforcement to increase the support material and the combination of the two Climbing or structural reinforcement of crane attachment.
