STRAND REINFORCING METHOD TO REINFORCE STEEL PLATE GIRDER BRIDGE DEPEND ON COMPOSITION FIXATIVE REINFORCING PART AND THERE OF APPARATUS

摘要

PURPOSE: A steel wire reinforcing method of a steel plate girder bridge using a composite anchorage-reinforcement part is provided to prevent buckle without damaging a steel plate girder, to reinforce by re-tensioning and to prevent damage caused by corrosion. CONSTITUTION: A steel wire reinforcing method of a steel plate girder bridge using a composite anchorage-reinforcement part comprises the steps of installing an iron frame(110) on both ends of a steel girder plate(10) of a steel plate girder bridge, forming a special concrete layer(120) to the inside of the iron frame(110), fixing an anchor bracket(130) to the outside of the iron frame(110) and the special concrete layer(120) by a high tensile bolt(150), fixing a gusset plate to both sides of the steel girder plate(10), forming a special concrete layer(120) to the lower part of the gusset plate, fixing primary and secondary saddles to the special concrete layer(120) by using the high tensile bolt(150), hanging a steel wire(W) on the primary and secondary saddles and connecting both ends of the steel wire(W) to an anchorage(400) coupled to an anchorage bearing part(140) of the anchor bracket(130), then tensioning and fixing.
