FRICTION SEISMIC ISOLATION BEARING STRUCTURE
An objective of the present invention is to provide an earthquake isolation support capable of stably accommodating a vertical load and horizontal displacement of a bridge. According to an embodiment of the present invention, the earthquake isolation support comprises: an upper plate wherein the upper surface thereof is coupled to a superstructure of a bridge, and a first curved surface groove of a hemispherical shape is formed on the lower surface thereof; a lower plate of which the lower surface is coupled to a substructure of the bridge; a middle plate positioned between the upper plate and the lower plate, and provided with a second curved surface groove of a hemispherical shape, which is formed on the upper surface thereof to correspond to the first curved surface groove; a curved surface plate positioned between the upper plate and the middle plate and inserted into the first curved surface groove and the second curved surface groove, wherein the upper surface thereof has curvature corresponding to the first curved surface groove and the lower surface thereof has curvature corresponding to the second curved surface groove; a support plate positioned between the middle plate and the lower plate; and a guide installed on a side of the upper plate to be extended to come in contact with the middle plate or the lower plate.
본 발명의 일 실시예에 따른 지진 격리 받침은, 상면이 교량의 상부 구조물에 결합되고, 하면에 반구 형상의 제 1 곡면홈이 형성되는 상부판; 하면이 교량의 하부 구조물에 결합되는 하부판; 상부판과 하부판 사이에 위치되고, 상면에 제 1 곡면홈에 대응하도록 반구 형상의 제 2 곡면홈이 형성되는 중간판; 상부판과 중간판 사이에 위치되고, 상면이 제 1 곡면홈에 상응하는 곡률을 갖고 하면이 제 2 곡면홈에 상응하는 곡률을 가지며, 제 1 곡면홈과 제 2 곡면홈에 삽입되는 곡면판; 중간판과 하부판 사이에 위치되는 지지판; 및 상부판의 측면에 설치되어 중간판 또는 하부판에 접촉되도록 연장되는 가이드를 포함하는 것을 특징으로 할 수 있다.
