Product Description

Product Description

is a laminated rubber plate joint that spans the deck gap and carries traffic across it. Bonded steel inserts hold the plate flat under wheel loads while the rubber body stretches with deck movement from temperature change and traffic. Anchor bolts set the plate into the deck concrete on both sides, and a shaped groove drains water from the gap. It is installed on highway bridges, urban viaducts, ramps and rail decks.
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.

Functions

*Expansion adaptation: Absorbs bridge movement 20-120mm through rubber elastic deformation

*Waterproof sealing: Prevents rainwater and debris from penetrating girder gaps

*Shock absorption & noise reduction: Elastic material cushions wheel impact, reducing noise by 8-12 decibels

*Load transmission: Uniformly transfers vehicle loads to girders

*Safety protection: Prevents debris accumulation from blocking gaps

Product Features

 * Laminated rubber body with bonded steel inserts for vertical stiffness.
 * Anti-skid upper surface pattern for traffic and pedestrian safety.
 * Anchoring by cast-in bolts or anchor loops set in the deck concrete.
 * Bolted assembly segments supplied in one metre lengths as standard.
 * Water drains and sealing profiles fitted under the plate.
 * Adjustable to the average gap size measured on site.

Construction & maintenance
    *Before installation check rubber hardness, tensile strength and surface defects against specifications.
    *After cleaning, groove evenness ≤2 mm; weld anchorage bars ≥3d length; re-torque bolts to design value.
    *After opening to traffic, remove debris every half-year, flush de-icing salts in winter; replace immediately if rubber cracks or steel plates are exposed.

Structure
are consisted of rubber, reinforce steel plate, ranura, sealing block, fitting portion, nut plate, kidney-shaped cap, nuts and bolt.
