Product Description

Product Description

Rubber bridge expansion joint uses rubber as the main elastic element. It is anchored to the deck with embedded plates or reinforcing bars and relies on the shear/compression deformation of the rubber to absorb horizontal movements (30–150 mm) caused by temperature, concrete shrinkage & creep, and vehicle loads. The common types are "plate" and "accordion": steel load-bearing plates are vulcanized inside the rubber; wheel loads are distributed by the plates while the rubber provides vertical stiffness and damping/noise reduction; anchor bolts integrate the whole unit with the beam ends. During installation the joint is kept flush and connected to the deck waterproofing.
Technical features
    *High elasticity and impact resistance, noticeably reducing vehicle bump and noise.
    *Simple, lightweight construction; can be cut and assembled on site for fast installation and low cost.
    *Neoprene or EPDM compounds resist ozone, oil and ageing; design life 8–12 years.
    *Internal force rises with movement; ≥30 mm movement reserve is required. Not suitable when movement >150 mm.

Function

*Displacement Accommodation: Capable of accommodating multi-dimensional movements in longitudinal, transverse, and vertical directions
*Waterproof Sealing: Effectively prevents rainwater, snowmelt, and other liquids from penetrating bridge structures
*Load Transfer: Smoothly transfers vehicle loads, reducing impact forces on bridge structures
*Vibration Damping and Noise Reduction: Elastic properties of rubber material help absorb vibrations and reduce traffic noise
*Temperature Compensation: Adapts to environmental temperature changes, preventing structural damage caused by thermal expansion and contraction

Feature

*Excellent Durability: Service life up to 15-20 years with low maintenance requirements
*Superior Waterproofing: Multiple sealing designs ensure reliable waterproof performance
*High Load-Bearing Capacity: Capable of withstanding repeated heavy traffic loads
*Easy Installation and Maintenance: Modular design simplifies installation process with low maintenance costs
*Strong Environmental Adaptability: Maintains stable performance in temperature range from -40℃ to +60℃
*Good Environmental Performance: Recyclable materials meet environmental requirements
