Lead Seismic Isolation Bearing
The present invention relates to a frictional lead seismic isolation support, which functions as a bridge support installed in one direction and a fixing terminal at normal times, and functions as a frictional bridge support when a huge load is applied due to an earthquake and the like. To this end, the frictional lead seismic isolation support comprises: upper and lower side plates; an elastic pad in which a lead rod is inserted; a bolt unit provided as a bridge support at a fixing terminal at normal times; a stainless plate formed to function as a frictional bridge support when a huge load is generated; and a frictional material. Therefore, at normal times, when a horizontal force is generated on the upper plate of a bridge, resistance is formed by the hardness of the lead rod, while movement in an axial direction or in an axial direction and a perpendicular direction to the bridge is restricted by the bolt unit, thereby allowing frictional lead seismic isolation support to function as a bridge support for a moving terminal or a fixing terminal, whereas, when a huge load is generated due to an earthquake and the like, the bolt unit is broken such that the stainless plate and the frictional material may perform a slipping movement, thereby performing frictional seismic isolation. Consequently, maintenance costs can be reduced, and workability can be improved.
본 발명은 평상시에는 일방향 및 고정단에 설치되는 교량받침 역할을 수행하다가 지진과 같은 큰 하중 작용시에는 마찰형 교량받침의 역할을 수행하는 마찰형 납 지진격리받침에 관한 것으로, 상, 하측 플레이트와 납봉이 삽입된 탄성패드와 평상시 고정단 교량받침을 위한 볼트부 및 큰 하중 발생시 마찰형 교량받침 역할을 수행할 수 있도록 형성되는 스테인리스판, 마찰재로 이루어져 있어, 평상시에는 교량상판의 수평력 발생시 납봉의 강성에 의한 저항력을 형성함과 동시에 볼트부에 의한 교축방향 또는 교축방향 및 교축직각방향으로의 거동을 제한하여 가동단 또는 고정단 교량받침의 역할을 수행하고, 지진과 같은 큰 하중 발생시에는 볼트부가 파단되면서 스테인리스판과 마찰재가 미끄럼운동이 이루어져 마찰형 지진격리를 수행할 수 있는 마찰형 납 지진격리받침을 제공한다.
