SPRING RESTORING AND FRICTIONAL TYPE SEISMIC ISOLATOR
A spring restoring-type frictional seismic isolator is disclosed. A shear pin inserted into a polytron disc is vertically mounted on the middle of a lower plate and inserted into a bearing block. A slide plate attached to a lower surface of a flat plate of a glide support unit is glidably disposed on a slip plate attached to an upper surface of the bearing block to glide with a reduced friction coefficient to dissipate vibration energy. A first and a second horizontal vibration absorbing restoration unit are arranged side-by-side on both sides of the bearing block. An elastic member is arranged in parallel with a side surface of the bearing block in a first horizontal direction. A vibration absorbing mechanism unit is extended between two side walls of the glide support unit facing each other and supported by a support unit to support both ends of the elastic member. The vibration absorbing mechanism unit compresses the elastic member and allows the elastic member to return to an original state when the glide support unit glides on the upper surface of the bearing block in the first horizontal direction by an external force. Accordingly, vibration of the glide support unit in the first horizontal direction can be absorbed. Similarly, if a third and a fourth horizontal vibration absorbing restoration unit are arranged on both sides of the bearing block side-by-side in a second horizontal direction perpendicular to the first horizontal direction, vibration in the second horizontal direction can be absorbed. A plurality of vertical elevation resisting members can be added to resist an external force to move the glide support unit upwards to block vertical elevation of the glide support unit.
