Product Description
Bridge Expansion Joints, Modular Expansion Joints
Features:
1. Sturdy and Reliable
Our Unique Roadway Expansion Joint exhibits unrivaled engineering excellence. Crafted from high-strength 16Mn steel, the side and middle beams are designed to endure the heaviest of traffic and lateral impacts. The seamless welding of anchoring components to both the beams and the bridge deck ensures optimal load transfer to the abutment. This results in a structure that is both exceptionally robust and durable, making it perfect for bridges with design loads of over 20 tons and hanging capacities reaching up to 120 tons.
2. Sensitive Expansion
Featuring a cutting-edge displacement control system, our product includes advanced spring elements such as rubber springs, PTFE pressure bearings, and inclined support members. This sophisticated system ensures uniform displacement with minimal friction, allowing smooth and predictable expansion and contraction within each segment.
3. Smooth Bridge Deck and Comfortable Travel
Our innovative design ensures that the beam can freely expand and contract while maintaining a seamless bridge deck surface. This results in an uninterrupted, smooth, and comfortable driving experience, enhancing overall travel quality on the bridge.
4. Water Stopping and Corrosion Prevention
The expansion joint is equipped with a specially designed neoprene rubber sealing strip embedded in each steel beam group groove. This feature offers superior elastic deformation capabilities, ensuring excellent waterproofing and dustproofing. It effectively safeguards internal components and base bearings from corrosion and erosion, thereby extending the joint's lifespan.
5. Large Displacement and Convenient Selection
Manufactured to precise modular standards, our expansion joint provides a broad range of displacement capabilities from 80 to 1200mm. This versatility allows bridge design and construction teams to easily select the appropriate joint to meet specific needs of the bridge's expansion and contraction requirements.
Telescopic Resistance:
Single-Seam Expansion Joint
1. The compression force during contraction is 0.1KN/m.
2. The longitudinal shear force within the working range of the expansion joint is 2.0KN/m.
Multi-Seam Expansion Joint
1. The compression force during contraction is 0.1KN/m.
2. The tensile force during stretching is 4.0KN/m.
