后张法预应力空心板梁施工控制要点

结合工作经验，根据后张法预应力空心板梁的特点，就场地准备及胎膜制作、模板制作安装、钢筋及钢绞线加工、混凝土浇筑、养护、拆模、钢绞线张拉、压浆及封头等施工控制要点作了介绍，以推广后张法预应力空心板梁的应用。

On the control points of the post-tensioned prestressed hollowslab beam

By combining with experience and connecting with the characteristics of the post-tensioned prestressed hollow-slab beam,some construction control points such as ground preparation,the making of fetal membranes,the making and installation of templates,the process of the steel bar and the steel strand,the pouring of concrete,the maintenance,the form removal,the tension of steel strand,the grouting and head plate are introduced,so as to expand the application of the post-tensioned prestressed hollow-slab beam.
