摘　　要：为解决南京新媒体大厦项目在施工场地狭小、现场拼接起重设备转动半径受限、无法进行现场拼接的问题,进行了受限空间大跨度劲性钢结构施工技术的研究。通过在工厂完成整根钢梁加工,运至现场后整根一次性吊装到位,结合全过程控制和现场协调,安全完成了大跨度劲性钢结构施工,总结的经验可为类似工程提供借鉴。To solve the problems that the construction site of Nanjing New Media Building project is narrow,the rotation radius of onsite splicing lifting equipment is limited and the onsite splicing cannot be carried out,the construction technology of large span rigid steel structure in confined space is studied.After the whole steel beam is processed in the factory and transported to the site,the whole steel beam is hoisted in place at one time.Combined with the whole process control and onsite coordination,the construction of large span rigid steel structure is completed safely.The experience summarized can provide reference for similar projects.
