Product Description

Product Description

Modular Expansion Joints Accommodate 160–3000 mm Movements
Modular expansion joints, also called GQF-MZL modular bridge joints, are composed by boundary beams, middle beams, cross girders, displacement control systems, bridge bearings, anchoring components and rubber sealing belts. modular expansion joints are suitable for longitudinal movements of 80 mm to 1200 mm.

Having good bearing capacity and stability, modular expansion joints can accommodate movements in every direction and rotations about every axis. Their individual displacement control and load transfer systems enable bridges to adapt the movement of the beam caused by temperature and ensure the traffic safety.

Functions

*Large movement adaptation: Modular multi-gap design, movement 80-1200mm

*Waterproof sealing: Rubber sealing strip prevents water and debris infiltration

*Load transmission: Support crossbeams uniformly transfer wheel loads to girders

*Shock absorption: Elastic sealing strip cushions impact and reduces noise

*Displacement coordination: Control system maintains uniform expansion of all gaps

Features

*High load capacity: Single-gap bearing capacity ≥50kN/m

*Large movement: Maximum 1200mm movement

*Reliable waterproofing: Sealing strip fits tightly, no leakage under 0.2MPa water pressure

*Excellent durability: Aging and fatigue resistant with 30-year design life

*Easy maintenance: Sealing strip can be replaced separately

Structure

Modular expansion joints are composed by boundary beams, middle beams, cross girders, displacement control systems, bridge bearings, anchoring components and rubber sealing belts.
