KZQZ Series Hyperbolic Spherical Bearings

The hyperboloid spherical steel bearing is a new type of seismic isolation bearing developed on the basis of the original spherical bearing and the working principle of friction pendulum bearing. It is formed by changing the plane friction pair of spherical bearing to large radius spherical friction pair and setting shear resistance device. The plane friction pair is replaced by the large radius spherical friction pair to provide friction displacement during earthquake; When the earthquake occurs, the shear device is cut off, which plays the role of damping. When the earthquake occurs and the horizontal transverse force exceeds the preset value, the shear resistance of the limit device pin And security screw When the bearing is sheared, the lateral limit constraint of the bearing is relieved, and the large radius spherical friction pair can slide freely in the transverse direction. Through the friction resistance, the seismic energy is gradually consumed, and the seismic period is prolonged to achieve the effect of shock absorption and earthquake resistance; After the earthquake, the self weight of the structure can form a restoring force to reset the bearing.

The bearing does not contain rubber and other aging materials, and with reliable anti-corrosion technology, it has good durability and can achieve a service life of up to 100 years.
