Product Description
Bridge Expansion Joints, Modular Expansion Joints
Features:
1. Sturdy and Reliable
The side beams and middle beams of this expansion joint are expertly crafted from resilient 16Mn steel, engineered to withstand the vertical load of heavy, high-traffic vehicles and horizontal impacts. The anchoring components are firmly welded to both beams and the bridge deck, ensuring vehicle loads are efficiently transferred to the abutment. This meticulous design results in a structurally sound and durable product, ideal for bridges with design loads up to steam - over 20, and hanging - 120.
2. Sensitive Expansion
The device's displacement control system features spring elements such as rubber springs, PTFE pressure bearings, or inclined support members. This ensures consistent displacement and minimal friction during expansion and contraction across each group.
3. Smooth Bridge Deck and Comfortable Travel
Our device guarantees the beam's free expansion and contraction displacement while ensuring the bridge deck joints form a smooth, unified surface. This provides a seamless and comfortable driving experience, enhancing overall travel quality.
4. Water Stopping and Corrosion Prevention
Fitted with a neoprene rubber sealing strip embedded in each steel beam group's groove, this product excels in elastic deformation, waterproofing, and dustproofing. It effectively shields the internal components of the expansion joints and the base bearings from erosion, ensuring longevity and reliability.
5. Large Displacement and Convenient Selection
Designed and manufactured according to a standard modulus, this device offers a displacement range from 80 to 1200mm. Bridge design and construction departments can effortlessly select the appropriate specification based on the actual expansion and contraction requirements of the bridge superstructure, ensuring precise application and optimal performance.
Telescopic Resistance:
