Zusammenfassung:	The present invention relates to a composite through bridge and a construction method thereof. The composite through bridge comprises: a pair of steel girders extending in a throttle direction in a bridge lower structure, installed to be spaced from each other in a throttle orthogonal direction, and provided with a steel bracket that is integrally formed to protrude in a lower end at an internal side; a steel floor beam manufactured to be a grid-type unit coupled to the steel bracket to connect lower ends of the steel girders; and a reinforced concrete slab formed to be deposited on an upper surface of the steel floor beam in a site. 본 발명은 합성구조로 제작된 하로형 철도교 및 그 시공방법에 관한 것으로, 상기 합성구조로 제작된 하로형 철도교는 교량하부구조에 교축방향으로 연장되며 교축직각방향으로 서로 이격되도록 설치되며 내측 하단에 돌출되도록 강재 브라켓이 일체로 형성된 한 쌍의 강재 거더; 상기 한 쌍의 강재 거더 하단을 연결하도록 강재 브라켓에 결합되는 격자형태의 유닛으로 제작된 강재 가로보; 및 상기 강재 가로보 상면에 현장 타설되어 형성되는 철근콘크리트 슬래브;를 포함한다.
