Product Description

Product Description

Laminated Rubber Bearing – Standard and Sliding Types for Different Bridge Span

Bridge rubber bearings are crucial connecting components in bridge structures, installed between the superstructure and piers to transfer loads, accommodate deformations, and provide seismic isolation. Manufactured by bonding multiple steel plates and rubber sheets through high-temperature vulcanization, they utilize rubber's elastic deformation to accommodate bridge rotation and displacement, effectively protecting the bridge structure and extending its service life.

Material
• Base Material: High-quality natural rubber or chloroprene rubber
• Reinforcement: Q235 steel plates as stiffening layers
• Protective Layer: Weather-resistant outer coating
• Accessories: Stainless steel sliding plates, PTFE plates

Core construction
    *Reinforcing steel plates, 2–4 mm thick, restrain lateral rubber bulging and provide high vertical stiffness.
    *Rubber layers (chloroprene CR or natural NR, 55–65 IRHD) supply shear flexibility and energy dissipation.
    *Typical sizes: 200 × 150 mm to 600 × 500 mm rectangular; thickness from 14 mm upward; load capacity 500–20 000 kN.

Introduction

    The laminated rubber bearing pads are made of several layers of natural rubber with reinforced steel inserted through sulfuration and adhesion. Laminated rubber bearings have enough stiffness and elasticity to transfer all load on bridge span structure to pier. Additional, it can bear the horizontal displacement, rotation and transformation caused by load.

    The laminated rubber bearing pads can reduce the pier vibration and accommodate the horizontal movement on the bridge span structure caused by the temperature changing and thermal expansion.

Function

• Load Bearing: Reliably transfer vertical loads from bridge superstructure

• Displacement Accommodation: Allow for thermal expansion and contraction

• Rotation Capacity: Adapt to beam end rotations

• Vibration Damping: Provide cushioning during earthquakes

• Stress Distribution: Evenly distribute loads to prevent stress concentration
