JCF-I Concrete-Free Reinforced Simply-Supported Comb-Type Expansion Joint

Scope of Application

Displacement range: 160mm ≤ e ≤ 400mm

Project Type: For noise-sensitive 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.

  • Reinforced simple support

    Fan-shaped dual-rib comb plates with multi-pass welds to embedded steel. The direct weld connections enhance structural integrity.

  • Effective maintenance

    Sectional maintenance and rapid installation with unitized design
