大连国际会议中心钢结构工程施工关键技术

Key Construction Technology of Steel Structure in Dalian International Conference Center

大连国际会议中心主体结构采用多支撑筒体大悬挑、大跨度复杂空间结构体系,建筑造型独特,结构异常复杂,施工难度大,技术要求高。对大连国际会议中心钢结构工程施工技术进行了研究和探讨,重点介绍了竖向筒体型钢框架钢骨结构悬空安装技术、大悬挑大面积楼层桁架群塔安装技术、大跨度空间网格结构安装技术、空间弯扭结构安装技术和空中连廊安装技术等施工技术。这些技术措施保证了大连国际会议中心钢结构工程的顺利实施,确保了工程质量、施工安全和施工进度。

The main frame of Dalian International Conference Center adopts large span complex spatial structure system with many supporting tubes and large cantilevers.With a distinctive styling and very complex structure , the construction of Dalian International Conference Center is very difficult and requires high techniques.The construction technology of steel structure project in Dalian International Conference Center was studied and discussed in this article , emphasizing on the hanging installation technique of vertical tube steel frame steel reinforced structure ; the installation technique for large cantilever and large area floor truss towers , large span spatial grid structures , spatial flexural-torsional structures and overhead corridors , etc.All the above technical measures effectively guaranteed the smooth implementation of the steel structure project of Dalian International Conference Center , and ensured the project quality , construction safety and construction schedule.
