Round Laminated Bearing Pad

The Round Laminated Bearing Pad is a high-quality product designed to meet the specific requirements of bridge construction. It is constructed using multiple layers of rubber sheet and thin steel plate, which are carefully superimposed through pressure vulcanization. This unique composition provides the bearing with exceptional vertical stiffness, enabling it to effectively support vertical loads. Additionally, the bearing exhibits excellent elasticity, allowing it to adapt to the rotational movements of the beam end.

One of the key features of this product is its ability to undergo significant shear deformation. This characteristic is crucial in accommodating the horizontal displacement of the superstructure, ensuring optimal performance and stability. Furthermore, the Elastomeric Rubber Bridge Bearing Pad offers remarkable seismic resistance, effectively reducing the dynamic load on both the upper structure and the pier. This feature is particularly important in enhancing the overall safety and durability of the bridge.

In conclusion, the Elastomeric Rubber Bridge Bearing Pad is a reliable and versatile solution for bridge construction projects. Its superior design and exceptional performance make it an ideal choice for engineers and contractors seeking to optimize the functionality and longevity of their structures.

Round Laminated Bearing Pad features reinforced steel plates that are sandwiched between layers of rubber through vulcanization and molding manufacturing process to form a homogeneous unit.

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.

Round laminated bearing pad has similar structure with rectangular laminated bearing pad. It is made of NR or CR rubbers with several steel plate inserted. The rubber and steel plate are inserted, glued and vulcanized together for stable and even bearing load and tensile strength.

Features:

• Capable to withstand severe vertical loads and external forces.
• High accommodation of movements caused by expansion, contraction, concrete creep effects and shrinkage, etc.
• Allow for rotations of the bearing in any horizontal axis caused by deflections or misalignments.
• Absorb vibrations and isolate sounds.
• Great traction resistance.
• Corrosion free in that the steel plates are embedded in the rubber without contact of air.
• Easy to install.

Application

• Round laminated bearing pad is commonly used in the applications where the inclination is larger than 10°.
• It is widely used in the curved bridge, skew bridge and column pier bridge.
