Large-span truss construction method
The invention belongs to the technical field of building construction, and particularly relates to a large-span truss construction method which comprises the steps of laying a sliding supporting structure and a track, installing a sliding trolley, assembling a steel truss, installing a lifting system, sliding, turning over the steel truss, hydraulically lifting the steel truss to a design position, unloading the steel truss and the like. The construction method provided by the invention is not restricted by construction environment factors such as a basement, can adapt to a narrow construction site, and realizes integrated construction of sliding, overturning and lifting of the heavy steel truss which is not assembled right below; the steel truss is installed through a ground horizontal splicing method, the steel truss can be inserted in advance for construction, the steel structure construction period is effectively shortened, and meanwhile the risk of cross operation with civil engineering is avoided; in addition, the overturning angle of the steel truss is controlled by a computer system, synchronization of pushing and lifting of the steel truss is achieved, the steel truss is turned up stably, the construction quality is improved, the safety risk is reduced, limitation of construction environment factors such as a basement is avoided, and the installation efficiency is improved.
本发明属于建筑施工技术领域，具体涉及一种大跨度桁架施工方法，包括铺设滑移支撑结构及轨道、安装滑移小车、拼装钢桁架、安装提升系统、滑移、钢桁架翻转、液压提升钢桁架至设计位置和卸载钢桁架等步骤；本发明提供的施工方法，不受地下室等施工环境因素的制约，能适应狭小的施工场地，实现非正下方拼装的重型钢桁架滑移、翻转、提升一体化施工；通过地面卧拼法安装钢桁架，能提前插入钢桁架施工，有效缩短钢结构施工工期，同时避免与土建存在的交叉作业的风险；另外，钢桁架翻转角度由计算机系统控制，实现钢桁架顶推和提升的同步性，使钢桁架稳步翻起，提高施工质量，降低了安全风险，且不受地下室等施工环境因素的制约，提高安装效率。
