中川机场钢结构屋盖支撑架滑移关键技术

On key technique for brace sliding of steel structure roof at Zhongchuan Airport

依托于中川机场项目,研究了指廊钢结构屋盖中支撑架滑移的关键技术,对曲面空间网格结构分块、滑移导轨铺设、支撑架在滑移和拼装工况下的设计和验算、网架拼装过程中的变形控制等问题进行了探讨,以顺利完成钢结构屋盖的安装。

Based on the program of Zhongchuan Airport,the paper researches the key techniques for the brace sliding in the roof of pier steel structure,and explores the curved-spatial grid structure block,pavement of the sliding guide rail,the design and calculation of the brace under the sliding and assembly conditions,and the deformation control in the grid assembly process,so as to complete the installation of the steel struc-ture roof.
