The present invention relates to a construction method for demolition and replacement of a bridge superstructure that secures constructability and economic feasibility using steel beams and hydraulic jacks, and to steel beams used therein. The construction method comprises the steps of: expanding the concrete of a bridge substructure; lifting a superstructure of a bridge by placing actuators on the expanded concrete and removing an abutment device; supporting the superstructure of the bridge by disposing an actuator on the substructure of the bridge; supporting the superstructure of the bridge by placing steel beams on the expanded concrete; and sliding the superstructure of the bridge by placing the actuator on the steel beam.
본 발명은 강재빔과 유압잭을 이용하여 시공성과 경제성을 확보한 교량 상부구조물의 철거와 교체를 위한 시공방법 및 이에 이용되는 강재빔에 관한 것이다. 상기 시공방법은 교량의 하부구조물의 콘크리트를 확장하는 단계; 확장된 콘크리트 상에 액추에이터를 배치시켜 교량의 상부구조물을 리프팅하고 교좌장치를 제거하는 단계; 교량의 하부구조물 상에 액추에이터를 배치시켜 교량의 상부구조물을 지지하는 단계; 확장된 콘크리트 상에 강재빔을 배치시켜 교량의 상부구조물을 지지하는 단계; 상기 강재빔에 액추에이터를 배치시켜 교량의 상부구조물을 슬라이딩 이동시키는 단계;를 포함하는 것을 특징으로 한다.
