Round Laminated Bearing Pad

The round laminated bearing pad is a high-quality product designed for bridge construction.It is a type of bridge bearings. Several layers of rubber sheets and thin steel plates make it. They press these layers together using pressure vulcanization. This special composition gives the bearing great vertical stiffness. This allows it to support vertical loads well. The bearing is very elastic. This helps it adjust to the beam end’s rotation.

A key feature of this product is its ability to handle significant shear deformation. This feature is key for handling the horizontal movement of the superstructure. It helps ensure good performance and stability. The elastomeric rubber bridge bearing pad provides excellent seismic resistance. It reduces the dynamic load on the upper structure and the pier. This feature is key for making the bridge safer and more durable.

The elastomeric rubber bridge bearing pad is a strong and flexible option for bridges. Its great design and top performance make it perfect for engineers and contractors. They want to improve how their structures work and last longer.

The Round Laminated Bearing Pad has reinforced steel plates. Someone sandwiches these plates between layers of rubber. A vulcanization and molding process creates a single, strong unit.

Advantages:

Round laminated bearing pads are among the most important laminated bearing pads. Manufacturers make standard round laminated bearing pads from chloroprene rubber (CR) or natural rubber (NR). The chloroprene rubber laminated bearing pad works from -25 °C to 60 °C. The natural rubber laminated pad, or cold-resistant pad, functions well between -40 °C and 60 °C.

Round laminated bearing pads have a similar structure to rectangular laminated bearing pads. Manufacturers make them from NR or CR rubbers with several steel plates inserted. They insert and glue the rubber and steel plates together. Then, manufacturers vulcanize them to ensure stable bearing loads and tensile strength.

Features:

• • Capable of withstanding severe vertical loads and external forces.

  • Expansion, contraction, concrete creep, and shrinkage cause high movement flexibility.

  • Allow for rotations of the bearing in any horizontal axis caused by deflection or misalignment.

  • Absorb vibrations and isolate sounds.

  • Great traction resistance.

  • The rubber embeds the steel plates without contact with air, making them corrosion free.

  • Easy to install.

  Application

  • Round laminated bearing pads are commonly used in applications where the inclination is larger than 10°.

  • It is widely used in the curved bridge, skew bridge, and column pier bridge.
