摘要
Abstract
The roof structure of the newly built Jingdezhen North Railway Station adopts a right-placed quadrangular conical grid structure welded with spherical nodes.The grid thickness is 1.8～4.8 meters,and a direct-placed grid structure is adopted.The maximum span is 69 m and the roof slope is about 5%.The lower chord of the grid frame is connected to the concrete column through earthquake-resistant spherical steel bearings.The reliability of steel grid lifting is ensured by monitoring on-site lifting methods,synchronous monitoring and lifting process monitoring.The combination with the construction technology in this project can provide a good guiding effect for the hoisting construction of the grid.关键词
