浅谈先张法预应力梁板施工

Discussion on Pretensioned Prestressing Slab Construction

先张法预应力梁板因其节省材料,自重轻,减小砼梁的竖向剪力和主拉应力,结构简单,安全可靠,便于安装等优点,在国内桥梁建设中被广泛应用。本文对先张法预应力梁板的施工从准备、张拉、放张等方面结合实际施工,进行了简述。

Pretensioned prestressing slab, with its advantages such as material-saving, light weight, reducing the vertical shear of concrete beams and the main tensile stress, simple structure, safe, reliable and easy to install, is widely used at domestic bridge construction. Combining the actual construction, the paper discusses the aspects such as preparation, tension, release sheets.
