A steel box girder is provided to reduce the manufacturing cost by recycling a cable bracing, to secure the inner space, and to reduce the weight of a bridge. A steel box girder(100) is composed of a flange(30) in which a side plate(20) is welded to both sides of a bottom plate, and a cable bracing(50) crossed from both sides of the bottom plate toward the upper part of each side plate. The flange is attached to the upper part of the side plate, and the cable bracing is connected to both sides of the bottom plate and the upper part of the side plate. The cable bracing is detachably installed in the upper part of the both sides of the bottom plate and the upper part of the side plate. An anchorage(70) is installed in the both sides of the bottom plate and the upper part of the side plate. Both ends of each cable bracing are connected to the anchorage. A coupling hook(90) is installed at both ends of the cable bracing. The coupling hook is inserted into the anchorage. |
