Product Description
Bridge Expansion Joint, Modular Expansion Joint
Features:
1. Sturdy and Reliable
Crafted from rolled 16Mn steel, the side and middle beams of this expansion joint are engineered to endure the vertical load of heavy traffic and horizontal impacts. Each anchoring member is welded firmly with the beams and the embedded steel of the bridge deck, ensuring the vehicle load is reliably transferred to the abutment. This makes the joint structurally sound, durable, and suitable for design loads exceeding steam - 20, hanging - 120 of the bridge.
2. Sensitive Expansion
Featuring a sophisticated displacement control system composed of spring elements like rubber springs, PTFE pressure bearings, or inclined support members, this device ensures uniform displacement with minimal friction during expansion and contraction.
3. Smooth Bridge Deck, Comfortable Travel
Designed to allow free expansion and contraction displacement, this device also ensures the bridge deck joints form a seamless whole, guaranteeing a smooth and comfortable driving experience.
4. Water Stopping and Corrosion Prevention
Equipped with a neoprene rubber sealing strip embedded in the groove of each steel beam group, this product offers excellent elastic deformation, waterproof and dustproof properties. It effectively shields the internal components and bottom bearing of the expansion joints from erosion.
5. Large Displacement, Convenient Selection
Designed and manufactured according to specific moduli, this device offers displacement options ranging from 80 to 1200mm, allowing bridge design and construction departments to choose based on the actual expansion and contraction needs of the bridge superstructure.
