FRICTION PENDULUM TYPE SEISMIC ISOLATION SUPPORT WITH FINE TUNED WEDGE

摘要

The present invention, the upper block for supporting the bridge deck; a support block installed on the pier to support the upper block and the bridge top plate; a flow support part interposed between the support block and the support block so that the support block and the upper block are in close contact with each other so as to be spaced apart; Limiting the flow amount of the upper block to limit the flow of the bridge top plate by the flow support unit within a specific range, installed in any one of the upper block or the support block, opposite the other one of the upper block or the support block wedges positioned to be; And the upper block or the support block and the wedge are installed in close contact with the wedge to restrict the flow direction of the upper block or the support block by the wedge to closely connect the wedge to the upper block or the support block. After performing fine adjustment to maintain a constant distance between the wedge and the upper block or the support block, after the wedge is connected in a slidable state by temporarily coupling the adjustment fixing part when installing the wedge It is possible to fix the wedge, and since a plurality of the wedges are installed in close contact with the upper block or the support block, when the bridge top plate flows, the load is concentrated on the wedge of any one or part of the plurality of wedges It is characterized in that it can be prevented.
