Product Description

Product Description

Round Laminated Bearing Pad - Standard and Sliding Type

Round laminated bearing pad is one of the most important shape laminated bearing pad. Standard round laminated bearing pad is made of chloroprene rubber (CR) or natural rubber (NR). The chloroprene rubber laminated bearing bed is suitable for -25 °C to 60 °C. The natural rubber laminated bearing pad, which is also called cold resistant bearing pad can be used in -40 °C to 60 °C.

PTFE Bearing Pads - Better for Large Span Bridge for Small Friction

PTFE bearing pad, also called PTFE bearing pads, is an important material in bridge construction. The dimpled PTFE sheet bonded to the laminated bearing pad for structure friction coefficient reduction and displacement capacity improvement. It provides a sliding surface for expansion accommodation, the elasticity of the bearing pad is high enough to suit the rotation of beam end, and also the shear deformation is efficient to cope with the horizontal of the superstructure. Here are round and rectangular two main shapes of PTFE bearing pad introduced to you.

Rectangular Laminated Bearing Pad - Excellent Shear deformation & Elasticity

Rectangular laminated bearing pad, one of most popular type in laminated bearing pad, is made of chloroprene rubber (CR) or natural rubber (NR). The chloroprene rubber laminated bearing pad is suitable for environments where the temperature ranges from -25 °C to 60 °C. If the working temperature ranges from -40 °C to 60 °C, you can choose the natural rubber for raw material.

Features:

(1)Quality materials including natural rubber, neoprene complying with AASHTO standards.

(2)Allow for expansions and contractions of precast steel structure of bridges.

(3)Capable to control load distribution, meanwhile accommodate thermal and end-beam rotational movements.

(4)Vibration, sounds and shocks isolation.

(5)Avoid excessive load eccentricity and edge compression.

(6)Simple but robust structure.

(7)Lower price than laminated elastomeric bearing.

(8)High cost effectiveness.

(9)Minimal maintenance is needed.

Application

• Laminated bearing pad is suitable for the bridge which span is no larger than 30 m and needs little displacement.
• The rectangular laminated bearing pad is suitable for right bridge.
• Round laminated bearing pad is suitable for curved bridge, column pier bridge or skew bridge.
• PTFE laminated bearing pad is suitable for large span, multi-span continuous beam and simply supported beam and other large displacement bridges.

Classification

As laminated rubber bridge bearing has so many kinds including standard and customized types. They can be chosen according to different classification

• According to the using condition

  • Normal temperature laminated rubber bearing. It is made of Chloroprene rubber (CR), which is suitable for the -25 °C to +60 °C temperature applications.
  • Cold resistant laminated rubber bearing. It is made of natural rubber (NR), which can perform well in -40 °C to +60 °C.

• According to the structure

  • Round shape laminated rubber bearing.
  • Rectangular shape laminated rubber bearing.

• According to sliding type

  • Fixed type. It refers to the standard laminated rubber bearing without sliding performance.
  • Sliding type. The top surface are designed with PTFE board for sliding.

Structure

The laminated rubber bearing pad can be divided into standard laminated bearing pad and sliding laminated bearing pad.

• Standard laminated rubber bearing pad is composed of natural or chloroprene rubber and reinforced steel plates.
• Sliding laminated bearing pad is composed of natural or chloroprene rubber, reinforced steel plates and PTFE sliding plate.
