Product Description
Step into the future of infrastructure with our Bridge Expansion Joints and Modular Expansion Joints, where pioneering technology meets unparalleled engineering prowess. Crafted with precision, these joints are the ideal solution for modern infrastructure, fulfilling the dynamic demands with ease.
Features:
1. Sturdy and Reliable
Our expansion joints are engineered with superior strength and endurance, featuring side and middle beams made from robust 16Mn steel. Designed to withstand intensive vehicle traffic, both vertically and horizontally, the integral anchoring elements are expertly welded to the beams and bridge deck, ensuring efficient load transfer to the abutment. An outstanding choice for bridges with challenging design loads, supporting steam over 20 and hanging up to 120.
2. Sensitive Expansion
Our device, equipped with a cutting-edge displacement control system, innovatively combines spring elements like rubber springs, PTFE pressure bearings, and inclined support members. This allows for a smooth and frictionless displacement process during expansion and contraction, delivering unparalleled reliability across all assemblies.
3. Smooth Bridge Deck and Comfortable Travel
Elevate your driving experience with our expansion joint device, designed to ensure effortless beam expansion and contraction, maintaining an unbroken bridge deck surface. It offers a seamless and comfortable journey, enhancing travel quality with its superior design.
4. Water Stopping and Corrosion Prevention
Our expansion joints come equipped with a high-performance neoprene rubber sealing strip, ingeniously positioned in each steel beam groove. This excels in elastic deformation, waterproofing, and dustproofing, forming a robust barrier against erosion, protecting internal components and base bearings, thereby significantly extending the lifespan and reliability of the joints.
5. Large Displacement and Convenient Selection
Designed with a standard modulus, our device offers a broad displacement range of 80 to 1200mm, providing bridge design and construction teams the flexibility to choose the perfect specification. This ensures exceptional performance and precise application, meeting the distinct expansion and contraction demands of the bridge superstructure.
Telescopic Resistance:
