摘　　要：采用预应力单索作为点支式幕墙的支承结构,可达到通透、美观的建筑效果,但是这种结构柔性大、变形大、结构空间小,施工上有一定的难度。本文结合哈尔滨国际会展体育中心工程,介绍这种结构体系中拉索的施工方法。As the support structure of a support-type curtain wall, prestressed single cables have such architecture effects as visual and beautiful, but they also have some construction difficulties including large flexibility, big deformation, and small structural space. In this article, authors state construction methods of pulling cables in this structure system in Harbin International Meeting and Exhibition Center Project.
