摘要
结合昆明西山万达广场项目情况,介绍了外挂式动臂塔式起重机支撑体系受工程结构特点的影响,塔式起重机标准C型梁无法直接安装与使用的情况下,对外挂动臂塔式起重机"C型梁+叠合梁"的常规支撑体系进行了优化与改进,减小支撑体系的复杂程度,降低施工难度,同时采取了一系列保质、降危、增效的施工方法,提高施工效率和安装精度,保证施工质量。
Based on the situation of Kunming Xishan Wanda Plaza project, introduces the influence of plug-in jib tower crane support system by structural characteristics, the situation of tower crane standard C type beam cannot be directly installed and used, the conventional dynamic plug-in support system ＂C beam ＋ overlapped beam＂ for optimization and improvement. Reduce the complexity of support system, reduce the difficulty of construction, and taken a series of quality, reduced risk, and improve the efficiency of the construction method, the installation accuracy of construction efficiency, ensure the quality of construction.
