Product Description
Bridge Expansion Joint, Modular Expansion Joint
Features:
1. Robust and Reliable
Crafted from high-grade rolled 16Mn steel, the side and middle beams of this expansion joint endure the immense vertical loads and horizontal impacts from heavy traffic. With securely welded anchoring members, vehicle loads are efficiently transferred to the abutment, ensuring structural integrity and durability. This makes it perfect for bridges designed to handle steam loads over 20 tons and hanging loads up to 120 tons.
2. Highly Responsive Expansion
This device's displacement control system includes rubber springs, PTFE bearings, and inclined support elements. These components ensure uniform displacement with minimal friction, enabling seamless expansion and contraction.
3. Smooth Bridge Deck for Comfortable Travel
This innovative design ensures unrestricted expansion and contraction of the beam while maintaining a smooth, unbroken bridge deck surface for a comfortable driving experience.
4. Effective Water Stopping and Corrosion Resistance
Each steel beam set features a neoprene rubber sealing strip, providing excellent elastic deformation and waterproofing. This protective strip shields internal components from dust and corrosion, safeguarding the integrity of the expansion joints and bearings.
5. Large Displacement Range for Easy Selection
Designed with modular flexibility, this device accommodates displacements from 80 to 1200mm. Bridge designers and construction teams can select the optimal configuration based on the specific expansion and contraction needs of the superstructure.
Telescopic Resistance:
Single-Seam Expansion Joint
1. Compression force during contraction is 0.1KN/m.
2. It withstands a longitudinal shear force of 2.0KN/m within the working range.
Multi-Seam Expansion Joint
1. Compression force during contraction is 0.1KN/m.
2. Tensile force during expansion is 4.0KN/m.
