Construction method of large-span steel tank framework
The construction method comprises the steps that in a target construction area, according to the lofting requirement, variable cross-section U-shaped channel steel is installed on a prefabricated steel tank framework clamping groove unit, and after installation, an opening of the variable cross-section U-shaped channel steel faces upwards; according to the lofting requirement, force-bearing ground rail steel channels are installed on the tops of the two side plates of the variable cross-section U-shaped steel channel correspondingly, and openings of the two force-bearing ground rail steel channels deviate from each other after installation; according to the lofting requirement, a reinforcing rib system is installed on the steel tank framework clamping groove unit, and installation of the large-span steel tank framework unit is completed; and according to the extending direction of the large-span steel tank framework, the adjacent large-span steel tank framework units are spliced in sequence, and overall installation of the large-span steel tank framework is completed. The invention aims to solve the problem of low construction precision of a large-span steel tank framework obtained by splicing and assembling a plurality of large-span steel tank framework units due to errors generated in prefabrication and transportation of the large-span steel tank framework units.
本发明公开了一种大跨度钢槽骨架的施工方法，包括：在目标施工区域，根据放样要求，将变截面U型槽钢安装到预制好的钢槽骨架卡槽单元上，安装后所述变截面U型槽钢的开口朝上；根据放样要求，在所述变截面U型槽钢的两侧板的顶部分别安装承力地轨槽钢，安装后两个所述承力地轨槽钢的开口相互背离；根据放样要求，在所述钢槽骨架卡槽单元上安装加强筋体系，完成大跨度钢槽骨架单元的安装；根据大跨度钢槽骨架的延伸方向，依次将相邻的大跨度钢槽骨架单元进行拼接，完成大跨度钢槽骨架的整体安装。本发明目的在于解决由于大跨度钢槽骨架单元在预制及运输中产生误差，导致由若干大跨度钢槽骨架单元拼接组装得到的大跨度钢槽骨架施工精度低的问题。
