2 APPARATUS AND METHOD FOR STRENGTHENING OF GIRDER BRIDGE BY SECONDARY POST-TENSIONING
According to one embodiment of the present invention, an apparatus for reinforcing a girder bridge using secondary tension is provided to reinforce a girder arranged between lower structures of the bridge. The apparatus for reinforcing a girder bridge using the secondary tension includes: a plurality of anchoring members provided on an outer side surface of the girder; and a tensioning member fixed between the anchoring members to provide lifting force and compression stress to the girder, wherein the tensioning member has a double reinforcing structure and provides the lifting force and the compression stress to the girder at the same time.
본 발명의 일 실시예에 따른 2차 긴장을 이용한 거더교의 보강장치는 교량의 하부구조물 사이에 배치되는 거더를 보강하기 위한 거더교의 보강장치에 있어서, 상기 거더의 외측면에 복수로 구비되는 정착부재, 및 상기 정착부재 사이에 고정되어 상기 거더에 상승력 및 압축응력을 제공하기 위한 긴장부재를 포함하고, 상기 긴장부재는 이중 보강 구조를 가지며 상기 거더에 상승력 및 압축응력을 동시에 제공한다.
