Product Description
Bridge Expansion Joints, Modular Expansion Joints
Features:
1. Sturdy and Reliable
Our expansion joint boasts superior craftsmanship. With side and middle beams forged from robust 16Mn steel, it is meticulously engineered to endure the immense vertical pressure from high-traffic, heavy-tonnage vehicles and lateral impacts. The seamless welding of anchoring components to both the beams and bridge deck ensures efficient load transfer to the abutment, resulting in a structurally sound, long-lasting product. This makes it the ideal choice for bridges designed to handle loads of steam over 20 and accommodate hanging up to 120.
2. Sensitive Expansion
The displacement control system of this device incorporates advanced spring elements like rubber springs, PTFE pressure bearings, or inclined support members. This innovative design guarantees uniform displacement and minimal friction, ensuring smooth and efficient expansion and contraction within each group.
3. Smooth Bridge Deck and Comfortable Travel
Our cutting-edge design ensures that the beam expands and contracts freely while preserving a smooth, unified bridge deck surface. This results in a seamless, comfortable driving experience, enhancing overall travel quality.
4. Water Stopping and Corrosion Prevention
This expansion joint is equipped with a high-quality neoprene rubber sealing strip embedded in the groove of each steel beam group. It provides excellent elastic deformation capabilities, waterproofing, and dustproofing, effectively shielding internal components and base bearings from erosion and corrosion.
5. Large Displacement and Convenient Selection
Manufactured according to modular standards, this device offers an impressive displacement range from 80 to 1200mm. This flexibility allows bridge design and construction departments to select the ideal specification to meet the actual expansion and contraction needs of the bridge superstructure.
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.
