Product Description
Bridge Expansion Joints, Modular Expansion Joints
Features:
1. Sturdy and Reliable
Our Suzhou Bridge Expansion Joint boasts exceptional craftsmanship, utilizing robust 16Mn steel for both the side and middle beams. This superior engineering ensures it can withstand immense vertical loads from high-traffic, heavy-tonnage vehicles, as well as substantial lateral impacts. The meticulously welded anchoring components secure both the beams and the bridge deck, ensuring efficient load transfer to the abutment. Consequently, this joint is not only structurally sound but also highly durable, making it ideal for bridges designed to handle steam loads exceeding 20 and hangings up to 120.
2. Sensitive Expansion
The displacement control system of our bridge expansion joint incorporates advanced spring elements, including rubber springs, PTFE pressure bearings, or inclined support members. This cutting-edge design ensures uniform displacement with minimal friction, facilitating smooth expansion and contraction within each segment.
3. Smooth Bridge Deck and Comfortable Travel
Our innovative design permits the beam to expand and contract freely, all while maintaining a consistent and smooth bridge deck surface. This ensures a seamless and comfortable driving experience for all users.
4. Water Stopping and Corrosion Prevention
Equipped with a neoprene rubber sealing strip embedded within the groove of each steel beam group, our expansion joint offers superior elastic deformation capabilities, waterproofing, and dustproofing. It effectively protects internal components and base bearings from corrosion and erosion.
5. Large Displacement and Convenient Selection
Designed according to modular standards, our product provides displacement ranges from 80 to 1200mm. This flexibility allows bridge design and construction departments to select the specifications that best meet the actual expansion and contraction needs of the bridge superstructure.
