COMPLEX SEISMIC ISOLATION BEARING CAPABLE OF ACCEPTING BOTH LONGITUDINAL EARTHQUAKES AND A SEISMIC ISOLATION BED USING THE SAME

摘要

PURPOSE: A complex seismic isolation bearing capable of accepting both longitudinal earthquakes and a seismic isolation bed using the same are provided to ensure easy manufacture and installation and support a large load in the event of an earthquake.;CONSTITUTION: A complex seismic isolation bearing comprises a ball bearing part and an elastic bearing part. The ball bearing part absorbs vibration in the transverse direction, and the ball bearing part comprises a lower sliding board(111) fixed to the floor of a building or a structure in which equipment is installed, an upper sliding board(112), and a steel ball(113) which is placed between the lower and upper sliding boards. The elastic bearing part is coupled to the upper sliding board of the ball bearing part and absorbs vibration in the longitudinal direction. The elastic bearing part comprises a housing(121) having a conical damping rubber seat, a core(122) which is coupled to equipment or the structure in which the equipment is installed and has a conical inclined surface, and a damping rubber(123) which is formed in a circumferential direction between the damping rubber seat of the housing and the inclined surface of the core.;COPYRIGHT KIPO 2012
