Pot bearing
The pot bearing is an elastic support device widely used in bridges, buildings and large steel structures.
It is designed to realize load transfer, displacement adjustment and shock absorption functions. The core structure consists of an upper steel plate, a stainless steel plate, a polytetrafluoroethylene skateboard, an intermediate lining, a rubber pressure plate and a lower steel plate.
The compression elasticity of the rubber and the friction characteristics of the skateboard are used to adapt to the complex deformation requirements of the structure.
Technical parameters:
Applicable temperature: suitable for -25℃ to 60℃
Vertical bearing capacity: usually 1000-50000KN and 1-80MN
Displacement: horizontal displacement ±50mm-±300mm
Angular capacity: ≤0.02rad
Friction coefficient: static friction coefficient: 0.03-0.05 dynamic friction coefficient: 0.01-0.03
Material: steel (Q235, Q345), natural rubber, chloroprene rubber
Features:
Large bearing capacity, large horizontal displacement, shock absorption and earthquake resistance, small friction coefficient, good durability, easy maintenance.
Application:
Highway bridges, railway bridges, urban overpasses, large span bridges,
