浅谈装配式钢结构在大高差坡地建筑施工中的应用

Discussion on Application of Prefabricated Steel Structure in Construction of Building on Slope with Large Elevation Difference

装配式钢结构在现代建筑特别是异形建筑中应用广泛。文章结合重庆市寸滩国际新城展示中心项目的实际施工情况,从锚固螺栓安装、大截面异型钢柱吊装、大跨度变截面钢梁吊装、室内多曲面弧型旋转步道安装等方面,对装配式钢结构体系的施工方法及要点进行阐述;进而对装配式钢结构在山地城市大高差坡地建筑中的施工和应用技术进行总结,为今后的同类型施工技术积累经验。

Prefabricated steel structures are widely used in modern construction,especially in irregular buildings.On the basis of practical construction of Chongqing Cuntan International New Town Exhibition Center project,this paper expounds the construction methods and key points of prefabricated steel structure system from installation of anchor bolts,hoisting of large-section irregular steel columns,hoisting of large-span variable-section steel beams,and installation of indoor multi-curved arc revolving walkways,and then it summarizes the construction and application technology of prefabricated steel structure in buildings on slope with large elevation difference in mountainous cities in order to accumulate experience for construction technology of the same type in the future.
