Large-span hyperbolic truss construction technology based on steel structure dome cinema project
The invention provides a large-span hyperbolic truss construction process based on a steel structure dome cinema project, and relates to the technical field of steel structure construction in house building engineering, and the large-span hyperbolic truss construction process comprises the following steps: S1, blanking assemblage flaw detection: after blanking assemblage is completed, inspecting internal defects, S2, hoisting stress analysis: before hoisting, carrying out numerical simulation on each working condition, and the hoisting method can meet the requirements. An independent square-section steel structure truss column temporary support is manufactured, spherical steel structure arc-shaped columns are symmetrically installed, and a stable system is formed by components, so that a conventional assembly jig frame and a full-space supporting frame are omitted, the construction period for erecting a scaffold and manufacturing and installing the jig frame is shortened, the field management cost and the mechanical rental cost are reduced, the steel consumption is reduced, and the energy consumption is reduced; and the construction period is shortened, so that the management cost is reduced, the energy consumption and pollution in the material production, transportation and use processes are reduced, and the defects of insufficient high-altitude assembling precision, low safety, low construction speed and the like are overcome by using various technologies.
本发明提供一种基于钢结构球幕影院工程大跨度双曲桁架施工工艺，涉及房屋建筑工程中的钢结构施工技术领域，包括：S1、下料组立探伤：下料组立完成后，对内部缺陷进行检验，S2、吊装受力分析：吊装前对各工况进行数值模拟，保证吊装方法均满足要求。采用制作独立方形截面钢结构桁架柱临时支撑，对称安装球形钢结构弧形柱，靠构件本身自成稳定体系，节省了常规拼装胎架和满堂支撑架，节省搭设脚手架和制作安装胎架工期，减少现场管理费和机械租赁费，减少了钢材用量，减少能耗，缩短工期，从而降低管理成本，降低材料生产、运输、使用过程中的能耗和污染，各技术使用，避免了高空散拼精度不足，安全性低，施工速度慢等弊端。
