Product Description
Bridge Expansion Joint, Modular Expansion Joint
Features:
1. Sturdy and Reliable
The side beams and middle beams of the CSXYXC Rubber Expansion Joint are crafted from robust rolled 16Mn steel, designed to endure the vertical load and horizontal impacts of heavy traffic. The anchoring members, firmly welded to the embedded steel of the bridge deck, ensure the vehicle load is reliably transferred to the abutment. This makes the expansion joint structurally sound and durable, perfectly suited for bridges with design loads of steam - over 20, and hanging - 120.
2. Sensitive Expansion
This innovative device features a displacement control system composed of spring elements, including rubber springs and PTFE pressure bearings, ensuring uniform displacement with minimal friction during expansion and contraction.
3. Smooth Bridge Deck, Comfortable Travel
The CSXYXC ensures seamless expansion and contraction, forming a smooth bridge deck joint. This results in a comfortable and smooth driving experience.
4. Water Stopping and Corrosion Prevention
Equipped with a neoprene rubber sealing strip embedded in each group of steel beams, this device offers excellent elastic deformation, waterproof, and dustproof capabilities, effectively protecting the internal components and bottom bearings from erosion.
5. Large Displacement, Convenient Selection
Engineered with a displacement range from 80 to 1200mm, this device allows bridge design and construction departments to select the appropriate size according to the actual expansion and contraction requirements of the bridge superstructure.
Telescopic Resistance:
Single-seam Expansion Joint
1. The compression force is 0.1KN/m during contraction.
2. Longitudinal shear force within the working range of the expansion joint is 2.0KN/m.
Multi-seam Expansion Joint
1. Compression force during contraction is 0.1KN/m.
2. Tensile force when stretching is 4.0KN/m.
