Product Description
Bridge Expansion Joint, Modular Expansion Joint
Features:
1. Sturdy and Reliable
Crafted with rolled 16Mn steel, the side and middle beams in this expansion joint are engineered to endure the vertical loads of heavy traffic and substantial vehicles, as well as horizontal impacts. The anchoring components are robustly welded to the embedded steel of the bridge deck, ensuring the vehicle load is effectively transferred to the abutment. This results in a structurally sound, durable solution, ideal for bridges designed to bear steam loads over 20 and hanging loads up to 120.
2. Sensitive Expansion
This device's displacement control system comprises advanced spring elements, including rubber springs, PTFE pressure bearings, and inclined support members. The setup guarantees uniform displacement and minimal friction during expansion and contraction for each group.
3. Smooth Bridge Deck, Comfortable Traveling
Ensuring the beam's free expansion and contraction, this device integrates seamlessly with bridge deck joints, promoting a smooth, uninterrupted driving experience.
4. Water Stopping and Corrosion Prevention
Equipped with neoprene rubber sealing strips embedded in each steel beam groove, this device provides excellent elastic deformation and superior waterproofing and dustproofing capabilities. It effectively safeguards internal expansion joint components and the bottom bearing from corrosion.
5. Large Displacement, Convenient Selection
Designed and manufactured based on a modulus range from 80 to 1200mm, this device offers bridge design and construction departments the flexibility to select the appropriate displacement according to the actual expansion and contraction requirements of the bridge superstructure.
Telescopic Resistance:
Single-Seam Expansion Joint
1. The compression force is maintained at 0.1KN/m during contraction.
2. The 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. The tensile force during stretching reaches 4.0KN/m
