The present invention relates to a lifting device for a bridge beam and a lifting method for the same. The lifting device for a bridge beam lifts a bridge beam by being installed between an upper end of a bridge pier and the bridge beam. The lifting device for a bridge beam comprises: a lower support bracket comprising a lower support plate, a pair of anchor lower guides vertically connected to one side of the lower support plate, and a lower holder installed on the upper surface of the pier and connected to an upper end of the each anchor lower guide; an upper support bracket comprising an upper support plate, a pair of anchor upper guides vertically connected to one side of the upper support plate, and an upper holder installed on the lower surface of the bridge beam and connected to an upper end of the each anchor upper guide; an anchor inserted into the each anchor upper guide and the anchor lower guide by being formed in the shape of a rod, wherein an upper end of the anchor is fixed to the anchor upper guide and a thread coupled to a fixing nut is formed at the center of the anchor; and a hydraulic jack installed between the lower support plate and the upper support plate. After the upper support plate is lifted as the hydraulic jack is operated, the upper support bracket is locked by the fixing nut. So, the bridge beam is lifted. The lifting device for a bridge beam can lift the bridge beam without damaging the pier or the bridge beam by being easily installed between the bridge beam and the pier while having a simple structure.
본 발명은 교량빔 인상장치 및 인상방법에 관한 것으로서, 교각 상단과 교량빔 사이에 설치하여 교량빔을 인상시키는 장치에 있어서, 하부지지판과, 상기 하부지지판의 일측에 수직으로 결합되는 한 쌍의 앵커하부가이드와, 상기 각 앵커하부가이드의 상단에 결합되고 상기 교각의 상부면에 안착되는 하부거치대를 포함하여 이루어지는 하부지지브라켓; 상부지지판과, 상기 상부지지판의 일측에 수직으로 결합되는 한 쌍의 앵커상부가이드와, 상기 각 앵커상부가이드의 하단에 결합되고 상기 교량빔의 하부면에 안착되는 상부거치대를 포함하여 이루어지는 상부지지브라켓; 봉 형상으로 이루어져 상기 각 앵커상부가이드와 앵커하부가이드에 삽입되고, 상단이 상기 앵커상부가이드에 고정되며, 중앙에 고정너트가 체결된 나사산이 형성되는 앵커; 상기 하부지지판과 상부지지판 사이에 설치되는 유압잭;을 포함하여 이루어지되, 상기 유압잭을 작동시켜 상기 상부지지브라켓을 상승시킨 후 상기 고정너트로 락킹함으로써 교량빔을 인상시키는 것을 특징으로 한다.
