Neoprene Rubber Bearing

◆◆ Neoprene Rubber Bearing are architectural bearings mainly made of chloroprene rubber, with the following characteristics:

1. Good Weather Resistance: Chloroprene rubber has excellent resistance to ozone, ultraviolet rays, and other environmental factors. It can be used for a long time under harsh climatic conditions without easily experiencing aging phenomena such as cracking. Its weather resistance is superior to that of natural rubber bearings. For example, in high-altitude areas with strong ultraviolet radiation, chloroprene rubber bearings can better maintain their performance.

2. Excellent Corrosion Resistance: It has good resistance to oils and certain chemical substances, and strong chemical corrosion resistance. It can work normally in environments where oil contamination or chemical pollution may exist, such as buildings near factory workshops and chemical facilities.

3. High Strength and Elasticity: It possesses high strength, which enables it to undergo moderate deformation when bearing the load of buildings and to recover well to its original shape after the load is removed. Its mechanical parameters such as elastic modulus can also be designed and adjusted according to the needs of building structures to meet the requirements of different architectural structures.

4. Outstanding Seismic Isolation Performance: As a seismic isolation bearing, it can effectively isolate seismic energy. When an earthquake occurs, it absorbs and dissipates the energy transmitted by seismic waves through its own deformation, thereby reducing the impact of the earthquake on the upper structure of the building. At the same time, it can also adapt to a certain extent to the deformation of the building caused by factors such as temperature changes and uneven settlement, playing a role in buffering and adjustment.

5. Good Mechanical Properties: It has sufficient vertical stiffness to reliably transmit vertical loads, and excellent elasticity to adapt to the rotation of beam ends and horizontal displacement. Additionally, it has good damping performance, which can absorb vibration energy, reduce bridge vibration, and improve seismic performance and driving comfort.

6. Easy Installation and Maintenance: It has a simple structure, facilitating easy installation without the need for complex construction techniques, thus saving time and costs. Maintenance is also relatively simple, requiring only regular inspection and replacement of seals.

◆◆ Neoprene Rubber Bearing possess excellent weather resistance, oil resistance, chemical corrosion resistance, and other properties, and have a wide range of applications, mainly covering the following fields:

1.Bridge Engineering: Suitable for bridge structures such as simply supported beam bridges and continuous beam bridges with small to medium spans. For example, rectangular ordinary chloroprene rubber bearings for highway bridges. Generally, ordinary plate-type chloroprene rubber bearings are applicable to bridges with a span of less than 30 meters and small displacement. Rectangular bearings are used for orthogonal bridges, while circular bearings are used for curved bridges, skew bridges, and cylindrical pier bridges.

2.Construction Engineering: Can be used as seismic isolation bearings for high-rise buildings. When an earthquake occurs, they absorb and dissipate the energy transmitted by seismic waves through their own deformation, reducing the impact of earthquakes on the upper structure of buildings. At the same time, they can also adapt to the deformation of buildings caused by factors such as temperature changes and uneven settlement.

3.Railway Tracks: Used in railway and tram tracks as elastic pads, which can reduce vibrations and noise when trains pass by and improve riding comfort.

4.Industrial Equipment: Can be installed at the bottom of equipment such as engines, compressors, and pumps as shock-absorbing bases to reduce vibrations and noise and protect equipment foundations; they can also be used for supporting precision instruments to prevent vibrations from affecting the accuracy of the instruments.

5.Transportation and Automotive Industry: Can be used as cushioning pads for automobile suspensions and truck compartments to improve driving smoothness and comfort and reduce road damage.

6.Hydropower Engineering: Can buffer the impact of water flow on engineering structures and ensure the stable operation of facilities.

◆◆ Installation Steps for Neoprene Rubber Bearing:

1.Review the design drawings to understand the bearing's model, specifications, and installation position.

2.Clean the surface of the bearing installation position to ensure the foundation is flat, clean, and free from looseness. Roughen the bearing pad stones to enhance bonding strength.

3.Determine the accurate position of the bearing based on the design drawings and on-site measurement results.

4.Place the bearing at the predetermined position and adjust it to a horizontal state.

5.Fix the bearing to the foundation using bolts or welding.

6.Check the levelness and verticality of the bearing to ensure it meets the design requirements. For adjustable bearings, adjust them to the correct height and angle.

7.Connect the superstructure to the bearing and ensure the connection is firm and reliable.

8.If the bearing requires fixed installation by welding, perform the welding operation and conduct a weld inspection.

9.Seal the joint between the bearing and the structure to prevent the intrusion of moisture and debris.

10.Cure the concrete in accordance with specification requirements to ensure it reaches the design strength.

11.After completing the installation, conduct a final inspection to ensure all installation parameters comply with the design and specification requirements.

The above steps provide basic guidance for the installation of chloroprene rubber bearings. However, in actual operation, adjustments need to be made according to specific project conditions and design requirements. Meanwhile, safety operating procedures shall be strictly followed during the installation process to ensure construction safety.
