摘要
An apparatus for disassembling an upper member of a bridge bearing and a disassembling method using the same are provided to facilitate installation and disassembling work for the bridge bearing by simplifying the structure of the bridge bearing. An apparatus for disassembling an upper member of a bridge bearing comprises a bracket(10), a hydraulic jack(20) and a hydraulic pump. The bracket(10) has an L-shape. The bracket(10) has an insert unit(11) at a top thereof to receive an upper member of a bridge bearing, and a flat plate unit(12) on which the hydraulic jack(20) is placed. The hydraulic jack(20) is placed on the flat plate unit(12) such that a lower part of the upper member of the bridge bearing makes contact with a cylinder(21). The cylinder(21) moves up and down by hydraulic pressure. The hydraulic pump supplies the hydraulic pressure through a hose connected to the hydraulic jack(20).
