Steel Disc Bridge Bearing Designs And Types - China

Disc bridge bearing features its lower profile comparing with pot

bearings owning a thicker confined elastomer, a pot and a piston.

It is

capable to accommodate rotations by deformations of urethane disc, which

enables the bearing to provide reliable earthquake resistance to

buildings or bridges.

The detail components of disc bridge bearing

Disc bridge bearing

Polyurethane disc The polyurethane disc is excellent in supporting superstructures and allowing unidirectional or multidirectional rotations.

Not only does the disc features allowable bearing stress about 2.3 times higher than traditional elastomeric bearings, but also has high resistance to chemical, corrosion, ozone and various environmental influences.

Threaded shear pin The shear pin, inserted into the middle of plate of polyurethane disc, transmits horizontal shear force between upper and bottom plates.

Limiting ring Urethane disc can accommodate rotations in any direction without lift- off, but it may extrude and exhibit “creep” under high vertical load over time.

Thereby, the limiting rings are provided to avoid the extrusion and deformation of the urethane disc.

Features:

With high vertical load capacity.

Low profile makes it a preference for bridges and buildings with narrow room for bearing.

Ideal for applications where anticipated rotations of bearings are no more than 0.03 radians.

Excellent durability of the rubber part.

Stainless steel, PTFE as well as lubricant in its dimples efficiently decrease the friction coefficient and ease the sliding movements.

With superior coatings for anti- corrosion and longer service time, such as high- solids zinc primers, zinc or zinc / aluminum thermal spray coatings, etc.

Custom coatings are also available.

Advance designs complying with ASTM A709 and AASHTO M270.

Low maintenance.
