摘　　要：某新建医院病房楼主体完工后,需要在13-15层新加大跨度的后锚固悬挑阳台,并对原结构进行加固,本文介绍了该工程设计和施工中的关键技术措施,提出了植筋、粘钢、斜拉多重防线的设计模式。工程实践表明,该技术措施在类似新加后锚固大跨度悬挑构件的设计、施工中具有一定的借鉴意义。A large span cantilevered balcony of post-installed need to be added after the main structure has been completed,the original structure＇ bearing capacity is insufficient due to loads increasing by the load. The technical measures of construction are introduced.The design patterns of multiple defense are conceived,such as： the planted bar,bonding steel,cable-stayed. The project completion shows that the technical measures in the large-span cantilevered beam has reference meaning to the design and construction of the cantilevered members.
