Rubber Bearing Detailed Description
1. Definition and Function
A rubber bearing, also known as an elastomeric bearing, is a structural component primarily made of rubber materials (natural or synthetic) and often reinforced with steel laminates. Its core function is to support and transfer loads between structural elements (such as bridge girders and piers, or building floors and foundations) while allowing controlled movement and reducing vibrations. Key functions include:
  • Load Transfer: Distributing vertical, horizontal, and rotational forces evenly across structures.

  • Seismic Isolation: Mitigating earthquake-induced vibrations by absorbing and dissipating seismic energy.

  • Vibration Damping: Reducing dynamic loads caused by traffic, machinery, or wind.

2. Types and Features
2.1 Laminated Rubber Bearing
  • Structure: Comprises alternating layers of rubber and thin steel plates, significantly enhancing vertical load - bearing capacity while maintaining horizontal flexibility.

  • Application: Widely used in bridges, high - rise buildings, and large industrial structures.

  • Benefits: High durability, excellent load distribution, and long - term stability.

2.2 Lead Rubber Bearing (LRB)
  • Structure: Integrates a lead core within a laminated rubber bearing, providing additional energy - dissipation capabilities.

  • Application: Ideal for seismic - prone regions, as the lead core deforms plastically during earthquakes to absorb energy.

  • Benefits: Superior seismic resistance, self - centering ability, and enhanced shock absorption.

2.3 Natural Rubber Bearing
  • Material: Made from natural rubber, offering high elasticity and good resilience.

  • Application: Suitable for low - to medium - load applications where environmental compatibility and cost - effectiveness are priorities.

  • Benefits: Excellent fatigue resistance, good performance at low temperatures, and eco - friendly.

2.4 Synthetic Rubber Bearing
  • Material: Utilizes synthetic rubbers (e.g., neoprene, EPDM) with customized properties.

  • Application: Preferred in harsh environments due to enhanced chemical resistance, weatherability, and aging resistance.

  • Benefits: High durability in extreme temperatures, resistance to ozone, UV, and chemicals.

3. Applications
  • Bridge Engineering: Supports bridge girders, absorbs traffic - induced vibrations, and accommodates thermal expansion/contraction.

  • Building Construction: Provides seismic isolation for high - rise buildings, reduces floor vibrations, and enhances structural stability.

  • Industrial Equipment: Cushions heavy machinery, minimizes operational vibrations, and protects equipment from damage.

  • Marine Structures: Used in docks and piers to withstand wave forces and vessel impacts.

4. Advantages
  • High Elasticity: Rubber's natural flexibility allows for large deformations without permanent damage.

  • Cost - Effective: Lower installation and maintenance costs compared to metallic bearings.

  • Corrosion Resistance: Rubber is immune to rust and corrosion, extending service life in various environments.

  • Customizability: Dimensions, load - bearing capacity, and material properties can be tailored to specific project requirements.

  • Environmentally Friendly: Many rubber bearings are recyclable, reducing environmental impact.
