Zusammenfassung:The present invention relates to a height adjustable type bridge bearing with a height locking function using locking nuts. The present invention is formed to: be able to adjust the height by varying the support height of an upper structure by an ascending and descending jack member for a new construction as needed; stably maintain the adjusted height by being fixated by the locking nuts in a mechanical way; and prevent an increase in the overall height of the bearing. The bridge bearing of the present invention: has an upper locking nut (5) to be screwed to move in a vertical direction in a lower protruding part (21) by including an upper plate (1), a lower plate (2), and a buffering member (3) and having the lower protruding part (21) formed in the lower plate (2); and maintains the ascending state of the lower plate (2) by being in contact with each other as either or both the upper locking nut (5) and the lower locking nut (6) move in a state where the lower plate (2) ascends by the extension of an extension jack member (42) by having a height adjusting plate (4) in the lower side of the lower plate (2), having an upward protruding part (41) formed in the height adjusting plate (4), having the extension jack member (42) pushing the lower plate (2) in the upward protruding part (41), and having the lower locking nut (6) in the upward protruding part (41). 본 발명은 승하강하는 신축 잭부재에 의해 상부구조물의 지지 높이를 필요에 따라 가변시켜서 조절할 수 있으며 조절된 높이를 록킹 너트에 의한 기계적인 방식으로 고정시켜 안정적으로 유지하면서도, 받침의 전체 높이 증가를 방지할 수 있도록 구성한 "록킹 너트를 이용한 높이 고정기능을 가지는 높이조절형 교량받침"에 관한 것이다. 본 발명의 교량받침은, 상부판(1), 하부판(2), 및 완충부재(3)를 포함하여, 하부판(2)에는 하향 돌출부(21)가 형성되어 있어 상부 록킹 너트(5)가 하향 돌출부(21)에 상하 이동하도록 나사결합되어 구비되고; 하부판(2)의 아래쪽에는 높이조절판(4)이 위치하는데, 높이조절판(4)에는 상향 돌출부(41)가 형성되어 있고, 하부판(2)을 밀어주는 신축 잭부재(42)가 상향 돌출부(41)에 구비되어 있고, 상향 돌출부(41)에는 하부 록킹 너트(6)가 구비되어 있어서, 신축 잭부재(41)의 신장에 의해 하부판(2)이 상승한 상태에서, 상부 록킹 너트(5)와 하부 록킹 너트(6) 중의 하나 또는 모두가 이동하여 서로 접하여서 하부판(2)의 상승 상태를 유지하는 구성을 가진다.
