A construction method of a bridge structure and a steel composite girder bridge using the same are provided to reduce a period of construction and to improve economical efficiency by reducing the time required for manufacturing a steel girder and having no necessity of an additional thermal processing stage, and to apply to a beam bridge which is unable to camber in the manufacturing process of a steel girder. A construction method of a bridge structure by introducing the camber of a bridge as the dead weight of a steel girder comprises the steps of preparing at least one steel girder(10) composed of an upper flange, a lower flange and a web, placing the central part of the steel girder by a support(20), fixing the end of the steel girder in the transverse direction to prevent the distortion or buckling of the steel girder, and compounding a reinforced concrete part(50) composed of a concrete deck into the upper flange of the steel girder, and then removing the support. |
