The present invention relates to a bridge bearing constructed between a lower structure and an upper structure of a bridge. In case a deteriorating existing bridge bearing is replaced with a new bridge bearing, a side reinforcing plate and a side anchor bolt are installed on both surfaces of a coping unit of the lower structure. The new bridge bearing is not jointed with an existing anchor bolt and is jointed with a bearing upper plate. So, the construction of the new bridge bearing without concrete breaking in an existing method is possible. Also, the new bridge bearing is replaced without concrete curing and the concrete breaking such that construction periods can be shortened and installation processes in a site can be minimized. Moreover, the bearing upper plate, which is a reinforcing material manufactured in advance in a factory, is used for the replacement of the new bridge bearing to enable an installation work to be carried out. Therefore, the replacement of the new bridge bearing and reinforcement of the coping unit can be performed at the same time. |
