The grid supports include three types of fixed supports, one-way and two-way, and each grade. Its horizontal bearing capacity, vertical pull-out force and overall strength of the support are all significantly improved compared to ordinary supports. This series of supports uses elastic damping elements. When the horizontal force reaches a certain level, the damping spring begins to elastically deform to achieve a buffering effect. When the structure turns a corner, the ball core rotates and releases the torque generated by the upper structure. During an earthquake, rigid anti-seismic measures and flexible vibration-absorbing measures work at the same time to withstand the huge seismic input energy. This can not only ensure the reasonable relative displacement of the upper and lower structures of the bridge, reduce the amplification factor of the seismic force, but also maintain the unity of the structure. . The bearing can withstand high-intensity earthquakes and has good seismic resistance and vibration reduction effect on engineering structures in high-intensity earthquake areas, especially in direct earthquake areas. Divided according to the shape of the support: rectangular plate rubber bearing b. circular plate rubber bearing.
Divided by rubber type: Neoprene rubber bearing (applicable temperature - ~ ℃) b. Natural rubber bearing (applicable temperature ~ ℃) EPDM rubber bearing (applicable temperature - ~ ℃ ).
According to structural type: . Ordinary rubber bearing b. PTFE skateboard-type rubber bearing (referred to as PTFE skateboard bearing) basin-type rubber bearing.
