PSC GIRDER MAKING METHOD USING UPPER AND LOWER PSC TENDON WITH STRAIGHT TENDON SETTING STRUCTURE

摘要

The present invention is to install the PSC tension material in both the upper and lower in the PSC girder, the lower portion of both ends to form a cross-sectional extension portion such as a sphere shape, the upper portion to form a pre-stress concentrated prevention end, bulb PSC girder It is a method of manufacturing a PSC girder that enables an efficient cross-sectional configuration as a tee, but solves the problems caused by the upper and lower tensile stress caused by the PSC tension material.;PSC girder, upper tensile stress
