The present invention relates to a seismic structure installed in an opening of a concrete structure (10) composed of a column and a beam. The seismic structure includes: an edge member (110) which has a ��shape and which is mounted in each edge of the opening of the concrete structure (10); a pair of horizontal members (120) facing each other by being installed in the opening of the concrete structure (10) in the horizontal direction and connected with the edge member (110); a pair of vertical members (130) facing each other by being installed in the opening of the concrete structure (10) in the vertical direction and connected with the edge member (110); a gap controlling member (140) which has one side fixed and coupled to both ends of the edge member (110) and the other side installed in an end of the vertical member (130) or horizontal member (120) to be overlapped; a connection bolt (310) coupling ends of the horizontal member (120) and the gap controlling member (140) or ends of the gap controlling member (140) and the vertical member (130); a ��shaped inner frame (200) installed in a ��shaped frame formed of the vertical member (130) and the horizontal member (120); and a gap maintenance bolt (410) having one side fixed and coupled to the surface of the vertical member (130) or the horizontal member (120) and the other side supporting the inner frame (200). |
