XCF-II Concrete-Free Sealed Comb Joint

Scope of Application

Displacement range: 40mm ≤ e ≤ 160mm

Project Types: For noise/waterproofing-critical projects;

Urban expressways/elevated highways

Features

  • Integrated Beam Anchoring

    Prefabricated bridge components enhance pull-out resistance, boosting overall anchorage strength between expansion joints and beams.

  • Concrete-Free Impact Resistance

    Steel impact baffles eliminate traditional concrete transition zones, preventing concrete degradation and improving impact durability.

  • Low-noise durability

    Arc-profiled interlocking combs reduce torque and noise. Monolithic steel construction minimizes vibration.

  • Integrated drainage

    Centralized drainage via waterproof sealing structure

  • Effective maintenance

    Sectional maintenance and rapid installation with unitized design
