大跨度现浇预应力空心板结构施工

Construction of Large-span Cast-in-situ Prestressed Concrete Hollow Slab Structure

以2008年奥运会北京射击馆为例,说明大跨度现浇预应力空心板结构的施工过程。着重介绍了保证混凝土浇筑密实的构造方法和防止轻质管上浮的技术措施。

This paper gives 2008 Beijing Olympic Game Shooting Gymnasium as an example, illustrates the construction procedure of large-span cast-in-situ prestressed concrete hollow slab. The paper emphatically introduces the structural method for concrete cast, as well as the technique measure to prevent light material tube from overflowing.
