中国海洋大学船形钢结构及采光顶施工关键技术

Key Construction Technology of Ship-shaped Steel Structure and Daylighting Roof of Ocean University of China

介绍了中国海洋大学海洋科教创新园区(西海岸校区)一期工程船形钢结构及采光顶的施工方案,解决了钢结构安装复杂的技术难题,并取得了速度快、质量好、低消耗的效果。通过有限元分析,得到了每步张拉的钢索张拉力大小,为实际张拉提供理论依据。合理的张拉顺序和适当的工具选择确保了安装的顺利进行。经过船形钢结构安装及吊索张拉、采光顶安装及吊索张拉、船形钢结构稳定索张拉等步骤,最终实现了预期的结构状态。该施工技术具有可行性和可靠性。

This paper introduces the construction scheme of the ship-shaped steel structure and daylighting roof of the first phase in Marine Science and Education Innovation Park(West Coast Campus)of Ocean University of China,which solves the complex technical problems of steel structure installation,and achieves the effect of fast speed,good quality and low consumption.Through the finite element analysis,the tension force of the steel cable tensioned at each step is obtained,and the theoretical basis for the actual tension is provided.Reasonable tensioning sequence and appropriate tool selection ensure the smooth installation.Through the steps of ship-shaped steel structure installation and sling tensioning,daylighting roof installation and sling tensioning,ship-shaped steel structure stability cable tensioning,etc.,the expected structural state is finally realized.The construction technology is feasible and reliable.
