结合保定市关汉卿大剧院和博物馆工程中的大跨度空间结构大型钢梁运输、现场拼装分段吊装,介绍了大型钢梁地面拼装胎架制作、三维坐标控制以及吊装过程。钢梁主要采用500t履带吊主吊、250t履带吊辅助的方式进行吊装作业。并对钢梁吊装过程中的变形进行验算,解决了大跨度空间结构钢梁安装的难题,保证了安装的质量,取得了很好的效果。
Combining with the large-span steel beam with long-span spatial structure in Guan Hanqing Grand Theater and Museum Project in Baoding City, the hoisting and assembling are carried out on site. The manufacture of large-scale steel beam ground assembling tire frame, three-dimensional coordinate control and lifting process are introduced. Steel beams mainly used 500t crawler crane hanging, 250t crawler crane auxiliary way to hoisting operation. The deformation of the steel girder during hoisting is checked, which solves the problem of installing the steel girder of the long-span space structure, ensures the installation quality and achieves good results.
