Construction method of ultra-large-span bilateral unequal-height steel truss roof
The invention discloses a construction method of a super-large-span bilateral unequal-height steel truss roof, which adopts a light-weight support jig frame to form an in-situ rapid assembly process in which the two ends of a steel truss are in an unequal elevation state, so that the construction safety and the construction efficiency can be effectively ensured. According to the construction method for the ultra-large-span double-side unequal-height steel truss roof, a computer control hydraulic synchronous lifting technology and a graded unloading falling position control technology are combined, meanwhile, structural response monitoring in the whole construction process is combined, and a safe-precise-efficient ultra-large-span double-side unequal-height steel truss refined double-control construction technology is formed. The problems that a traditional high-altitude bulk method is adopted for a large-span steel truss roof, an all-round scaffold needs to be erected, the construction period is long, and cost is high are solved.
本发明公开了一种超大跨度双边不等高钢桁架屋盖施工方法，采用轻量化支撑胎架，形成了钢桁架两端不等标高状态的原位快速拼装工艺，可有效保证施工安全及施工效率。本发明的超大跨度双边不等高钢桁架屋盖施工方法联合计算机控制液压同步提升技术及分级卸载落位控制技术，同时结合施工全过程结构响应监测，形成面向“安全‑精确‑高效”的超大跨度双边不等高钢桁架精细化双控施工技术。本发明解决了大跨度钢桁架屋盖采用传统的高空散装法需要搭设满堂彩脚手架，施工周期长且成本高的问题。
