Product Description
Our line of Bridge Expansion Joints, including the Modular Expansion Joints, represents the pinnacle of engineering excellence, designed to accommodate movement and thermal expansion in bridges seamlessly.
Features:
1. Sturdy and Reliable
Expertly forged from resilient 16Mn steel, the side and middle beams of our expansion joint boast unparalleled strength. This formidable construction is engineered to effortlessly manage substantial vertical loads from bustling heavy vehicles while absorbing horizontal shocks. The anchoring components are skillfully welded to both the beams and the bridge deck, ensuring vehicle loads are adeptly distributed to the abutment. This meticulous craftsmanship guarantees exceptional structural integrity and longevity, making it an exemplary choice for bridges with high design loads.
2. Sensitive Expansion
Equipped with a sophisticated displacement control system, our joint integrates advanced spring elements like rubber springs, PTFE pressure bearings, and inclined support members. These elements ensure a dependable and consistent displacement process, minimizing friction during expansion and contraction, facilitating a seamless operation across each group.
3. Smooth Bridge Deck and Comfortable Travel
Indulge in the luxury of a smooth ride with our expansion joint, ensuring the free expansion and contraction displacement of the beams. It meticulously maintains the bridge deck joints in a unified, seamless surface, guaranteeing an exceptionally comfortable and enjoyable driving experience, thereby elevating the overall travel quality.
4. Water Stopping and Corrosion Prevention
Boasting a high-performance neoprene rubber sealing strip embedded within each steel beam group's groove, our product excels in elastic deformation, waterproofing, and dustproofing. It offers superior protection for the internal components of the expansion joints and the base bearings against erosion, thereby enhancing durability and reliability for an extended service life.
5. Large Displacement and Convenient Selection
Ingeniously engineered to a standard modulus, our device offers a versatile displacement range of 80 to 1200mm. This adaptability allows bridge design and construction departments to effortlessly select the precise specification that satisfies the actual expansion and contraction needs of the bridge superstructure, ensuring precise application and optimal performance.
Telescopic Resistance:
Single-Seam Expansion Joint
1. Compression force during contraction is sustained at 0.1KN/m, ensuring steadfast performance and reliability.
2. The longitudinal shear force within the operational range of the expansion joint stands robust at 2.0KN/m, providing stability and resilience.
Multi-Seam Expansion Joint
1. The compression force during contraction is consistently maintained at 0.1KN/m, ensuring reliable performance.
2. The tensile force during stretching is impressively robust at 4.0KN/m, ensuring enduring durability and strength.
