SEPERABLE BRIDGE BEARING FOR ISOLATING VIBRATION AND METHOD FOR REPAIRING THEREOF

摘要

PURPOSE: A vibration reduction type separable railway bridge bearing and a repairing method thereof are provided to improve vibration/noise absorption capability using a high damping elastic bearing. CONSTITUTION: A vibration reduction type separable railway bridge bearing comprises an upper plate(1), a sliding plate, a lower plate(3), a stopper(3a), a side block(4), and a high damping elastic bearing(5). The upper plate comprises a movement restricting projection(1a) for restricting the horizontal movement of the upper plate in the left and right sides. The sliding plate is installed on the lower part of the upper plate. The lower plate is installed on the lower part of the upper plate to correspond to the upper plate. The stopper is formed on the lower plate and is positioned on a groove(1b) between movement restricting projections in order to restrict the movement of the upper plate. The side block is fixed and coupled in the stopper. The side block is positioned on the upper surface of the upper plate. The high damping elastic bearing is formed between the upper plate and the lower plate.
