Product Description
Bridge Expansion Joints, Modular Expansion Joints
Features:
1. Sturdy and Reliable
Our expansion joints are a paragon of superior craftsmanship, featuring side and middle beams constructed from resilient 16Mn steel. Engineered to withstand substantial vertical loads from heavy, high-traffic vehicles and lateral impacts, these joints ensure enduring reliability. The anchoring components are securely welded to both the beams and bridge deck, facilitating seamless load transfer to the abutment. This results in a structurally sound and durable solution, ideal for bridges designed to sustain steam loads exceeding 20 and suspensions up to 120.
2. Sensitive Expansion
The displacement control system incorporates state-of-the-art spring elements such as rubber springs, PTFE pressure bearings, and inclined support members. This cutting-edge design guarantees uniform displacement and minimal friction, enabling smooth expansion and contraction within each module.
3. Smooth Bridge Deck and Comfortable Travel
Our innovative design ensures that the beam freely expands and contracts while maintaining a smooth, cohesive bridge deck surface. This results in a seamless and comfortable driving experience for all vehicles, enhancing overall travel comfort.
4. Water Stopping and Corrosion Prevention
Equipped with a neoprene rubber sealing strip embedded in the groove of each steel beam group, this expansion joint excels in elastic deformation. It offers superior waterproofing and dustproofing capabilities, effectively protecting internal components and base bearings from erosion, ensuring long-lasting durability.
5. Large Displacement and Convenient Selection
Manufactured according to modular standards, this device features a displacement range from 80 to 1200mm. Such extensive flexibility allows bridge design and construction teams to choose the optimal specification, meeting the precise expansion and contraction needs of the bridge structure.
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.
