Description of pot bearings
 
Bridge pot bearings are the new generation of bridge bearings designed to meet
the demands of today's complex bridge structures. In modern highway engineerng,
the advent of longer span & continuous girder bridges, coupled with compound
curves and increased truckloads, have resulted in larger load and movements
concentrated on fewer piers, these loads and movement exceed traditional bridge
bearing capabilities. The Dynamic Bridge pot bearings are developed to meet
these complex design parameters.

 


Performances and Classifications of pot bearings 
 
A: Free sliding pot bearing: Has vertical rotation, longitudinal and horizontal gliding 
performances and its serial number is SX;
B: One-way sliding pot bearing: Has vertical rotation and one-way sliding
performance and its serial number is DX;
C: Fixed pot bearing: Only has vertical rotation performance and its serial number
is GD.

Advantages of pot bearings

Pot bearings are usually recommended when bearing rotations are large, compact
designs and long term servesability are required.

Pot bearings provides longer service life compared to elastomeric bearings.
Smaller in size compared to elastomeric bearings.
Longer maintenance time.

Pot bearings can sustain many cycles of very small and large rotations.
Economical repair as replacement of elastomer disc only.
Does not get effected by external atmospheric correction.
 
 


Application of pot bearing

Pot type rubber bridge bearing can be used in steel or concrete structures. These
low profiles, compact bearings are particularly useful to transmit large vertical load
while accommodating large movements and multi-directional rotation.Separate
mechanisms for rotation and translation (where applicable) provide minimum
eccentricity of the load and minimum frictional resistance to movement. High side
loads can also be accommodated simultaneously.

 
Technical Performance of pot bearing
 
A: Vertical rotation angle of the bridge Pot bearing should not be less than 40';
B: Vertical bearing capacity (KN) 1000-50000 of the Bridge Pot bearing is
divided into 28 grades. Horizontal bearing capacity of the non-gliding surface is
10% of the vertical.
C: Friction coefficient of the Bridge Pot bearing: Room temperature μ ≤ 0.04
