双层钢桁架建筑,箱型柱往往单根重量大,且高度高,因此在施工过程中需要采取有效吊装措施保证吊装作业的安全性和效率;同时柱底采用杯口基础,下面没有地脚螺栓固定,杯口浇筑混凝土前要需采取可靠措施临时固定,确保钢柱定位准确且稳固;双层钢桁架安装,需要考虑安装过程中的精度控制和工序交叉作业。文章主要针对钢结构箱型柱双层钢桁架的施工技术进行简要介绍。 Double-deck steel truss construction, box-type column is often a single weight, and a high degree of height, so in the construction process need to take effective hoisting measures to ensure the safety and efficiency of hoisting operations; at the same time column base with cup mouth, there is no foot below Bolt fixation, pouring concrete before pouring concrete to take reliable measures for temporary fixation to ensure accurate positioning of steel columns and solid; double-deck steel truss installation, the need to consider the accuracy of the installation process control and cross-operation process. The article mainly introduces the construction technology of double-deck steel truss with box-type steel structure.
