超高层动臂塔式起重机附着结构补强分析

ANALYSIS OF ADHESION REINFORCEMENT IN CONSTRUCTION OF SUPER HIGH-RISE BOOM TOWER CRANE

超高层建筑项目中核心塔体多采用动臂塔式起重机以满式起重机施工中的机动性。重庆俊豪项目A塔楼作为项目的主塔结构,形式为型钢混凝土柱–钢梁–钢筋混凝土核心筒–环带桁架结构,由于结构形式的特殊性,在选用起重机械的时候必须充分考虑起重设备的各项参数;同时由于项目周围市政环境复杂,安全性也应该被严格把控。超高层建具有大体量、超高度等特点,动臂塔式起重机的加固措施需慎之又慎,故可以对其附着采取一定的补强措施以保证质量和安全。

In the super tall building project, the core tower body adopts the movable arm tower crane to meet the maneuverability in the construction. As the main tower structure of the project, the A tower of Chongqing Junhao project is the type steel concrete column-steel beam-reinforced concrete core tube-ring truss structure. Due to the particularity of the structure, the parameters of the lifting equipment must be taken into full consideration in the selection of lifting machinery. At the same time, the safety of the municipal environment around the project is complicated and safety should also be strictly controlled. The super high-rise building has the characteristics of large volume, super height, and so on. The reinforcement measures of the boom tower crane should be cautious and careful, so it can be attached to the reinforcement measures to ensure the quality and safety.
