1. Structure: GPZ (KZ) Fixed Seismic Pot Rubber Bearing mainly made up by the upper seat plate, energy dissipation plate, sealing ring, rubber board, and a bottom basin and damping rubber composition. GPZ (KZ) DX (one-way movable seismic pot rubber bearing) and a middle steel plate, stainless steel slide and PTFE skateboard, lateral sliding device. Damping principle is when the support horizontal force is greater than the bearing designed vertical bearing capacity of 20%, energy consumption plate began to slip, the first isolation effect, then play the second damping effect of damping ring, bearing to seismic action, when the earthquake shock wave exceeds a certain limit, the series of rigid a seismic played third anti-vibration effect.
2. Performance:
A. Designed Vertical Bearing Capacity This series of bearing designed vertical bearing capacity is divided into 31 stages.
B. Horizontal Bearing Capacity
Fixed support for each direction and a One-way Movable Bearing non slip direction of the horizontal bearing capacity can bear bearing design capacity of 20%.
3. Coefficient of friction:
Normal temperature type support ( - 25 ° C to + 60 ° C ) design friction value u = 0.03, hardy type support ( - 40 ° C to + 60° C ) design friction value u = 0.06
4, Bearing Corner: Bearing allows for corner of 0.02rad.
