Product Description
Bridge Expansion Joints, Modular Expansion Joints
Features:
1. Sturdy and Reliable
Our Custom Roadway Expansion Joints feature side and middle beams made from resilient 16Mn steel, expertly engineered to withstand the demands of high-traffic, heavy-tonnage vehicles and directional impacts. The robust anchoring components are meticulously welded to ensure that vehicle loads are securely transferred to the abutment, resulting in a structurally sound and long-lasting solution, ideal for bridges with design loads of steam - over 20, and hanging - 120.
2. Sensitive Expansion
The innovative displacement control system of this device incorporates advanced spring elements like rubber springs, PTFE pressure bearings, or inclined support members, delivering uniform displacement and minimal friction during expansion and contraction within each group.
3. Smooth Bridge Deck and Comfortable Travel
Our cutting-edge expansion joint not only allows for unrestricted expansion and contraction of the beam but also ensures that the bridge deck joints form a cohesive, smooth surface. This attention to detail provides drivers with a seamless and comfortable travel experience.
4. Water Stopping and Corrosion Prevention
Featuring a neoprene rubber sealing strip embedded within the groove of each steel beam group, this product offers exceptional elastic deformation, waterproof, and dustproof capabilities. It effectively safeguards internal components and base bearings from erosion, ensuring longevity and reliability.
5. Large Displacement and Convenient Selection
Engineered and crafted to a precise modulus, this device accommodates displacements ranging from 80 to 1200mm. Bridge design and construction teams can easily select the appropriate specification based on the specific expansion and contraction demands 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.
