摘　　要：珠海机场T2航站楼主楼北侧幕墙下弦檐口吊顶主龙骨造型为大波浪双曲面造型,其造型复杂,起吊高度大,采用高空拼装方式不利于外形控制且高空焊接作业会产生较大的安全隐患,经综合研判采用地面原位拼装、分块提升吊装的方式大大降低了安全隐患,且精度控制容易得到保障。The main keel of the hanging ceiling under the string cornice of the north curtain wall of the main building of T2 terminal of Zhuhai Airport is shaped as a large wave hyperboloid shape,which is complex in shape and has a large lifting height.The adoption of high-altitude assembly is not conducive to shape control and high-altitude welding operation will bring great security risks.After comprehensive research and judgment,the adoption of ground in situ assembly and block lifting greatly reduces security risks.And the precision control is easy to be guaranteed.

关 键 词：幕墙 檐口 双曲面 原位拼装 分块提升 吊顶龙骨施工
