PRESTRESSING METHOD FOR TENDON AND CONSTRUCTION METHOD FOR GIRDER USING THE SAME
Provided is a tendon prestressing method which comprises: an anchor plate installation process of installing an anchor plate (10) on a base material in which a tendon installation hole (110) is installed; a primary prestressing process for installing a tendon (20) in the tendon installation hole (110) of the base material, anchoring the tendon to the anchor plate (10) by an anchoring device (200) by prestressing the same with a design prestressing force, and allowing the anchoring device (200) to be in contact with the base material or the anchor plate (10) and be supported; a secondary prestressing process of secondarily prestressing the tendon (20) by the design prestressing force so that the tendon (20) and the anchoring device (200) are integrally moved; and a fitting member insertion process of for inserting a fitting member (300) into a gap generated between the anchoring device (200) and the anchor plate (10) by the secondary prestressing process. Even if the length of the tendon is short, tension loss caused by slip loss can be minimized.
