Product Performance & Features：
1. Excellent Movement Capacity
The elastic properties of rubber allow the expansion joint to absorb longitudinal and transverse movements caused by temperature changes and traffic loads, ensuring stable operation of bridge structures.
2. Reliable Waterproof Performance
The integrated rubber sealing structure effectively prevents water, dust and debris from entering the bridge joint area, reducing structural damage and extending service life.
3. High Wear Resistance and Aging Resistance
Manufactured with high-quality rubber materials, the product offers excellent resistance to wear, weathering, fatigue and environmental conditions.
4. Easy Installation and Maintenance
The simple structure and mature installation process reduce construction difficulty and maintenance costs, making it suitable for new construction and bridge renovation projects.
5. Customized Manufacturing
Different widths, lengths, thicknesses, fixing methods and rubber materials can be customized according to engineering requirements.
Installation Method:
1. Preparation
Clean the reserved installation groove and check dimensions, elevation and concrete conditions before installation.
2. Positioning
Place the rubber plate expansion joint into the reserved groove and adjust the position and height according to design requirements.
3. Fixing
Secure the expansion joint using anchor bars, embedded components or fixing devices to ensure stability.
4. Concrete Casting
Pour high-strength concrete or special grouting material around the expansion joint and complete curing.
5. Inspection and Operation
Check the installation quality, surface levelness and movement performance before opening to traffic.
