Product Description
Embark on a journey through unparalleled innovation with our Bridge Expansion Joints. Our state-of-the-art Modular Expansion Joints are meticulously engineered to deliver exceptional performance and durability, setting a new benchmark in the industry.
Outstanding Features:
1. Unyielding Strength and Dependability
Crafted to perfection, our expansion joint's side beams and middle beams are forged from robust 16Mn steel, tailored to withstand the colossal vertical loads from heavy-duty, high-traffic vehicles and combat horizontal impacts. Each anchoring component is meticulously welded to both beams and the bridge deck, ensuring flawless transfer of vehicle loads to the abutment. This comprehensive design cultivates a product of unmatched structural integrity and longevity, ideally suited for bridges engineered to accommodate design loads up to steam - over 20, and hanging - 120.
2. Responsive Expansion Capabilities
This cutting-edge device, integrated with an advanced displacement control system featuring spring elements like rubber springs, PTFE pressure bearings, or inclined support members, ensures consistent displacement with negligible friction during expansion and contraction, guaranteeing smooth operation across each group.
3. Seamless Bridge Deck and Enhanced Travel Comfort
Engineered with precision, our device enables the effortless free expansion and contraction displacement of the beams, ensuring that bridge deck joints form a harmonious, unbroken surface. This thoughtful design promises a seamless and luxurious driving experience, significantly enhancing travel quality.
4. Advanced Water Resistance and Rust Protection
Incorporating a neoprene rubber sealing strip, innovatively embedded within each steel beam group's groove, this product excels in elastic deformation, waterproofing, and dustproofing. It offers exceptional protection for the internal components of the expansion joints and base bearings against erosion, ensuring prolonged durability and reliability.
5. Extensive Displacement Range and Effortless Specification Selection
Engineered to a precise standard modulus, this device offers an impressive displacement range from 80 to 1200mm. Bridge design and construction departments can easily choose the correct specification tailored to the actual expansion and contraction needs of the bridge superstructure, ensuring precise application and unparalleled performance.
Telescopic Resistance:
Single-Seam Expansion Joint
1. The contraction process operates under a compression force of 0.1KN/m.
2. Within the operational spectrum of the expansion joint, the longitudinal shear force is upheld at 2.0KN/m.
Multi-Seam Expansion Joint
1. Throughout contraction, the compression force is sustained at 0.1KN/m.
2. During stretching, the tensile force achieves a remarkable 4.0KN/m.
