摘要
介绍了大悬挑非对称空间立体管桁架,采用分段累计滑移的方式,成功完成苏州博览中心三期工程2号建筑屋面桁架的安装工作。对滑移前胎架的布置、滑移过程中的受力等问题进行了详细的分析计算,从技术措施上保证了方案的顺利实施。
This paper introduces that asymmetric spatial truss cantilever of the third phase No. 2 pavilion of expo roof truss was installed successfully by accumulative sliding method by segment. The author analyzes and calculates in detail the jig arrangement before sliding and loading during sliding,which can assure the construction is implemented frequently.
