摘　　要：在建筑工程中,网架结构以其跨度大、受力简单、抗震性能好、造型美观等诸多优点,故被广泛应用,大跨度钢网架结构整体提升施工关键技术是一种新型技术,并成为建筑结构中的常用技术。但大跨度钢结构网架施工跨度大、高度高,在国内网架行业具有一定的挑战性。因此,研究以河北省某物料场大跨度钢结构网架施工项目为例,阐述项目施工难点,讨论施工部署情况,研究案例施工流程、施工方法等技术要点,以期促进大跨度钢结构网架施工技术的发展。In current construction projects,the grid structure is widely used due to its advantages such as large span,simple stress,good seismic performance,and beautiful appearance.The key technology for the overall lifting construction of large-span steel grid structures is a new technology and has become an active field in current building structures.However,the construction of large-span steel truss structures with large spans and high heights poses certain challenges in the domestic truss industry.Therefore,taking the construction project of a large-span steel structure truss in a material yard in Hebei province as an example,this study elaborates on the construction difficulties of the case,discusses the construction deployment situation,and studies the technical points such as the construction process and methods of the case,in order to promote the development of large-span steel structure truss construction technology.
