PURPOSE: A bridge bearing having an excellent structural stability and maintainability is provided to obtain the work stability by reducing the height in which a bridge deck is lifted and to prevent a damage of a joining member by preventing impact from being directly transferred to the joining member. CONSTITUTION: A bridge bearing having an excellent structural stability and maintainability comprises a lower member(10), an upper member(20), a middle member(30), and a bracket member(40). The middle member is arranged between the upper and lower members, thereby transferring load transferred through the upper member to the lower member. The bracket member is installed in the lower member, thereby controlling horizontal movement and vertical movement of the upper member. Hanging portions(21) projected to outside are formed in both sides of the upper member. The bracket member comprises a fixing unit(41), a vertical unit(42), and a pressurization unit(43). |
