摘　　要：对于大型钢结构工业厂房,屋面网架结构施工面临高空作业的问题,若采用分件高空散装的方式,不但高空组装、焊接工作量大,施工难度大,对工人的要求也较高,而且安全防护困难,容易发生高空坠落等安全事故。为解决上述问题,采用一种超大型构件液压同步提升技术,即使用液压同步提升系统,将钢结构网架设计提升单元整体提升至设计安装位置,高空作业仅补装后装杆件,这样可大幅减少高空作业工作量,降低施工风险,提升施工效率。以大庆某汽车总装车间钢结构网架整体提升工程为例,对施工过程的总体思路、关键技术和施工重难点进行总结,以期为同类型施工提供参考。For large steel structural industrial buildings,the construction of grid roof structures faces the challenge of working at height.Adopting the method of piece-by-piece assembly and welding at height not only results in a large workload and high construction difficulty,but also places high demands on workers.Additionally,it is difficult to ensure safety protection,and safety accidents such as falling from height are prone to occur.To address these issues,an ultra-large component hydraulic synchronous lifting technology is adopted,which uses a hydraulic synchronous lifting system to lift the entire designed lifting unit of the steel structural grid to the designated installation position.Only post-installed rods are assembled at height,which significantly reduces the workload of working at height,lowers construction risks,and improves construction efficiency.Taking the integrated lifting project of a steel structural grid for an automobile assembly plant in Daqing as an example,this paper summarizes the overall approach,key technologies,and difficult points of the construction process,aiming to provide a reference for similar construction projects.
