Product Description

Product Description

acts as an "elastic hinge" that transfers loads from the super-structure to the piers while allowing rotation and horizontal movement. It is built by vulcanizing thin steel reinforcement plates and rubber layers together under heat and pressure—commonly called a "". When PTFE sheets or spherical steel components are added on the top and bottom, the range is extended to or spherical bearings to accommodate larger displacements or rotations.
Main types
    – displacement by shear deformation; most common.
    * – PTFE sheet on top slides against stainless steel (μ ≈ 0.03) for 50–300 mm long movements.

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 are made of several layers of natural rubber with reinforced steel inserted through sulfuration and adhesion. 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 can reduce the pier vibration and accommodate the horizontal movement on the bridge span structure caused by the temperature changing and thermal expansion.

Features

*Excellent accommodation for horizontal movement.

*Low friction coefficient.

*Absorb vibrations and isolate sounds.

*Easy to install.

*Completed products for suitable displacement requirements.

*Can be used in extremely low temperatures.

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
