Document Type and Number:
WIPO Patent Application WO/2020/006850
Kind Code:
A1
Abstract:
A pull-resistant rubber friction pendulum seismic isolation bearing comprises: two vertically opposing recessed plates (1); a rubber interlayer cushion (2), disposed between the two recessed plates (1); two vibration isolation plates (5), respectively disposed at an upper side of the upper recessed plate (1) and at a lower side of the lower recessed plate (1); friction sheets (3), disposed at an upper side and a lower side of the rubber interlayer cushion (2), and making respective contact with the two recessed plates (1); vertical disc springs (4), disposed between the recessed plates (1) and the vibration isolation plates (5), and connecting the same; a first cord (6), disposed between opposing inner sides of the two recessed plates (1); and a second cord (7), disposed between opposing inner sides of the two vibration isolation plates (5). The seismic isolation bearing provides multi-stage horizontal seismic isolation, isolates vertical seismic vibration, and further provides pull-resistance.
