摘　　要：清华大学新建光华路校区大楼工程为"筒中筒"结构超高层建筑,主楼内为混凝土核心筒内筒,外为钢管混凝土外筒。3层裙房为大跨度会议室,其屋顶钢梁长达23 m,钢梁在加工、运输、安装过程中均存在较大困难。故就裙房大跨度钢梁制作、安装施工技术进行了探讨。The building of the new guanghua road campus of tsinghua university is the supertall structure of the ＂tube and barrel＂ structure. The main building is the inner tube of the concrete core barrel and the outer tube of the concrete pipe concrete. F3 layer skirt room is large span conference room, its roof steel beam is 23m long, steel beam is in processing, transportation, installation process is very difficult. This paper discusses the production and installation of the large span steel girder.

关 键 词：大跨度钢梁 预拼装 安全防护
