<p>The present invention relates to an upper structure of a steel bridge used for a steel bridge which is composed of the lower structure of a steel pile and the upper structure of a steel girder. The upper structure of the steel bridge comprises: a plurality of pile caps which are arranged in parallel to each other to enable the steel pile to be inserted therein; the I-shaped girders which are installed in a longitudinal direction on one side of an upper portion of the pile cap; first cross beams which are disposed between the pile caps to connect the pile caps; and second cross beams which are disposed between the I-shaped girders to connect the I-shaped girders. According to the present invention, the bridge can be built regardless of a terrain, where a crane is hard to be landed, such as a stream, a pond, and a coast. Moreover, the present invention improves connection strength of a connection point using a girder connection bonding device to easily connect the upper structure of the steel bridge having a long span.</p> |
