某建筑工程无粘性后张预应力施工实践

The cohesionless prestressed construction practice of a construction project

笔者结合具体的工程实例论述了无粘性后张预应力在工程施工过程中的应用。根据工程的概况,文章讲述了无粘性后张预应力的各项施工准备工作和预应力的施工要求,并阐述了预应力筋下料穿束、安装固定、混凝土浇筑张拉施工、封锚等施工工序及取得的施工效果。

Combining with concrete engineering examples, the paper discusses the application of cohesionless prestressed members in the engineering construction. According to the project, this article describes non-sticky prestressed preparations and requirements, and construction details, and describes the tendon cutting wear beam, fixed, concrete pouring tensioned construction, anchor seal and other construction processes and construction results achieved.
