A pot bearing is a type of structural bearing used to support loads while allowing for rotational and translational movements. It consists of a cylindrical pot filled with elastomeric material or a sliding surface, typically made of steel or PTFE, which helps accommodate movements due to thermal expansion, settlement, or seismic activity.
Key Features:
- High Load Capacity : Designed to support heavy loads effectively.
- Movement Accommodation : Allows for vertical and horizontal movement as well as rotation.
- Durability : Made from robust materials, they resist wear and environmental effects.
Pot bearings are widely used in various applications, including:
- Bridges : They support superstructures, allowing for movement due to temperature changes and traffic loads.
- Buildings : Used in high-rise structures to manage differential settlements and seismic forces.
- Viaducts and Overpasses : Help accommodate dynamic loads and movements in these structures.
- Tunnels : Assist in supporting tunnel linings while allowing for ground movement.
The advantages of pot bearings include:
- High Load Capacity : Capable of supporting substantial loads, making them suitable for heavy structures like bridges and buildings.
- Flexibility in Movement : They allow for vertical and horizontal movement as well as rotation, accommodating thermal expansion and ground settlement.
- Durability : Constructed from robust materials, pot bearings resist environmental effects and have a long lifespan.
- Maintenance-Free : Typically require little to no maintenance, reducing long-term costs.
- Effective Load Distribution : They help distribute loads evenly, minimizing stress on structural components.
