摘要
大跨度钢结构具有结构跨度大、钢构件重量大、尺寸大、高度大以及焊接量大的特点,因此,必须采用独特的施工方法。采用整体顶升法,即将被提升结构在投影地面拼装好后,利用千斤顶顶升到设计标高处,可以有效减少高空作业量,整体施工效率较高且质量有保障。论文以费县通用机场项目为例,分析了项目施工难点,运用网架顶升施工技术,详细地介绍了施工过程和施工措施,指明了施工注意事项和安全保障措施。
Long-span steel structures have the characteristics of large structural span,large weight,large size,high height and large welding volume of steel members,so unique construction methods mustbe adopted.The overall jacking method is adopted,that is,after the lifted structure is assembled on the projection ground,thejack is used to jackup to the design elevation,which can effectively reduce the amount of high-altitude operation,and the overall construction efficiency is high and the quality is guaranteed.Taking Feixian General Airport Proj ect as an example,the paper analyzes the construction difficulties of the proj ect,introduces the construction process and construction measures in detail by using the grid j ackingconstruction technology,and pointsout the construction precautions and security measures.
