Beschreibung
Zusammenfassung:	A negative reaction resisting seismic isolation system is disclosed. The disclosed g seismic isolation system comprises: a lower supporting unit; a vertical support arranged on the lower supporting unit; a middle supporting unit arranged on the vertical support; an upper support which is arranged on the middle support and has a guide part vertically extending to face a side surface of the middle supporting unit; a horizontal sliding unit which is arranged between the middle supporting unit and the upper supporting unit and includes a SUS plate and a fluoroplastic plate for allowing the horizontal displacement of the upper supporting unit with respect to the middle supporting unit; and a restoring unit which is arranged between the guide part of the upper supporting unit and the middle supporting unit and provides force of restoration for the upper supporting unit by being contracted in response to the horizontal replacement of the upper supporting unit. The restoring unit includes an elastic body, a pressuring member connected with one end of the elastic body, and a guide road which penetrates the elastic body, the pressuring member, and the guide part. Therefore, the negative reaction resisting seismic isolation system can have resistance to the vertical negative reaction.
