摘要
针对某些大跨度桁架结构,结构下方起重机无法站位,分段吊装困难的问题;若采用常规的分件高空散装方案,需要搭设大量的高空脚手架,成本较高且存在较大的质量和安全风险。若此类结构采用“高空累积滑移”的施工方法来完成桁架结构的施工,将大幅降低安装施工难度,并于质量、安全和工期等均有利。
For some large-span truss structures,the crane below the structure can not stand,and the problem of segmental lifting is difficult,if the conventional high-altitude bulking scheme is used,a large number of high-altitude scaffolding needs to be set up,the cost is high and there is a large quality and safety. risk. If such a structure adopts the construction method of“ high-altitude cumulative slip” to complete the construction of the truss structure,the installation and construction difficulty will be greatly reduced,and it is advantageous in terms of quality,safety and construction period.
