Construction method of large-span arc-shaped steel structure
The invention relates to the technical field of large-span steel structure construction, in particular to a large-span arc-shaped steel structure construction method.The large-span arc-shaped steel structure comprises a steel structure bent beam, and the two connecting ends of the steel structure bent beam are both used for being fixed to a high-rise building main body frame during installation; a plurality of lightening holes are formed in the middle of a web of the steel structure bent beam at intervals; two through holes are formed in a web plate at the connecting end of the steel structure bent beam at intervals, the through holes are used for installing a bearing steel shaft in a matched mode during construction and installation, and a lifting piece is fixedly installed on the outer side wall of the middle of the steel structure bent beam. According to the method, in the mode that the large-span arc-shaped steel structure is welded and assembled on site, on-site welding and positioning of all lugs and other accessories can be conducted according to the current construction requirement, the time of high-altitude operation in the follow-up construction process can be effectively shortened, and the construction efficiency and safety are effectively improved.
本发明涉及大跨度钢结构施工技术领域，尤其是一种大跨度弧形钢结构施工方法，包括钢结构弯曲梁，所述钢结构弯曲梁的两连接端均用于在安装时固定在高层建筑物主体框架上，在所述钢结构弯曲梁的腹板的中部间隔设置有若干个减重孔；在所述钢结构弯曲梁的连接端处的腹板上间隔设置有两个贯穿孔，所述贯穿孔用于在施工安装时配合安装承重钢轴，在所述钢结构弯曲梁的中部外侧壁上固定安装有起吊件。本发明中在采用现场焊接组装大跨度弧形钢结构的方式能够根据当前施工的需求进行各耳座等配件的现场焊接定位，能够有效地减少后续施工过程中的高空作业的时间，有效地提高施工的效率及安全性。
