PURPOSE: A girder and a bridge construction method using the same are provided to be efficiently applied to the replacement of an aged bridge where minimum traffic control is required, and to the new construction site of a bridge where rapid construction is required, and so on by allowing rapid construction. CONSTITUTION: A girder(100) is formed to have an I-shaped cross section by concrete. A curved bolt insertion hole is formed at one end or both ends of an upper flange(110) to be combined with an upper flange(110a) of another closely installed girder(100a) by a curved bolt(200). A bridge construction method using the girder includes the following steps: installing multiple girders on an abutment or a pier(10) to allow the upper flanges of the multiple girders to touch each other; and installing a curved bolt through a curved bolt insertion hole of the closely installed multiple girders and fixing the girders to each other. |
