A constructing method for a PSC girder bridge using a fixing device controlling tensile force is provided to additionally tighten the second reinforced wires and improve the prestressing efficiency by prestressing the second reinforced wires and introducing the second tensile force. A constructing method for a PSC girder bridge using a fixing device controlling tensile force is comprises a step of installing first reinforced wires(1) at a PSC girder(10) and introducing the first tensile force to the PSC girder, a step of installing the PSC girder on the pier or the bridge and mounting a half-section precast floor plate(20) between upper flanges(12) of the PSC girders laterally placed, a step of introducing the second tensile force to the PSC girder by tightening second reinforced wires(5) placed at the PSC girder, a step of pouring the concrete on the upper side of a half-section precast floor plate and constructing the floor plate slab. |
