深圳前海世茂金融中心钢结构工程施工关键技术

Key Construction Technology of Steel Structure in Qianhai Shimao Financial Center of Shenzhen

前海世茂金融中心项目为"核心筒+外框钢结构"结构体系,塔楼外框整体呈逆时针45°旋转,外框辐射梁每层布置方式均不同,辐射梁间距不断变化,导致钢筋桁架楼承板跨度均有所不同。本文重点介绍了外框柱临时连接形式,钢筋桁架楼承板施工措施等安装技术,有效地保证了施工的工期、质量与安全要求。

Qianhai Shimao financial center project is'core tube+frame steel structure'structure system,the whole tower frame counterclockwise 45°rotation,frame radiation beam layout of each floor are different,the radiation beam spacing changes,resulting in steel truss Floor board span are different.Emphasis is placed on the temporary connection form of the outer frame column and the installation technology of the construction measures of the steel truss floor boards so as to effectively guarantee the construction period,quality and safety requirements.
