Features:
1. Sturdy and Reliable
Constructed with premium 16Mn steel, the robust side and middle beams of this advanced expansion joint are meticulously engineered to withstand the strenuous demands of heavy-traffic bridges. Boasting remarkable vertical load capacity and impressive horizontal impact resistance, the securely welded anchoring components ensure flawless load transfer to the abutments. This innovative design provides a structurally sound, durable solution tailored for bridges that bear design loads surpassing 20, and support hanging loads up to 120.
2. Sensitive Expansion
Our sophisticated displacement control system integrates cutting-edge spring elements, including rubber springs, PTFE pressure bearings, and inclined support members. This innovative configuration promises consistent movement with minimal friction, optimizing the device's expansion and contraction capabilities for seamless performance.
3. Smooth Bridge Deck and Comfortable Travel
Designed with precision, our device empowers the beams to expand and contract freely, ensuring a smooth, uninterrupted surface across the bridge deck joints. This seamless integration enhances the driving experience, providing travelers with an unmatched level of comfort and quality.
4. Water Stopping and Corrosion Prevention
Featuring a superior neoprene rubber sealing strip within each group of steel beams, this product stands out for its exceptional elastic deformation abilities. It delivers outstanding waterproofing and dustproofing, effectively protecting internal components from erosion, thereby ensuring long-lasting reliability and superior performance.
5. Large Displacement and Convenient Selection
Incorporating a standard modulus design, this device offers an extensive displacement range from 80mm to 1200mm. This versatility allows bridge construction teams to effortlessly select the most suitable specification, precisely tailored to the specific expansion and contraction requirements of the bridge superstructure, ensuring optimal precision and peak performance.
