摘　　要：某学校工程双曲米字梁轻钢屋盖为球形曲面,与两侧建筑连接处设置滑动支座,施工中针对空间造型复杂、安装精度要求高等难点,采用优化设计节点与构件分段等措施,保证了安装精度,取得了良好的经济效益。The light steel roof of the Beijing school’s hyperbolic rice-beam beam is a spherical curved surface,and sliding bearings are set at the connection between the buildings on both sides.During the construction,the optimization design of nodes and component segmentation measures are adopted for the difficulties of complex spatial modeling and high installation accuracy.The installation accuracy is guaranteed and good economic benefits are achieved.

关 键 词：轻型钢结构屋盖 双曲造型 米字梁 强轴垂偏
