Product Description
Bridge Expansion Joints, Modular Expansion Joints
Features:
1. Sturdy and Reliable
Our expansion joint exemplifies unparalleled craftsmanship, utilizing resilient 16Mn steel for both side and middle beams. Designed to endure colossal vertical pressures from high-traffic, heavy-load vehicles and lateral impacts, the meticulously welded anchoring components to both beams and the bridge deck ensure efficient load transfer to the abutment. This creates a structurally robust, durable solution ideal for bridges with steam design loads over 20 and hanging up to 120.
2. Sensitive Expansion
Featuring a sophisticated displacement control system, this device integrates advanced spring elements such as rubber springs, PTFE pressure bearings, or inclined support members. This ensures uniform displacement and minimal friction, enabling smooth, consistent expansion and contraction within each component group.
3. Smooth Bridge Deck and Comfortable Travel
Our innovative design facilitates seamless expansion and contraction of the beam, maintaining a smooth and continuous bridge deck surface. This results in an exceptionally 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 joint provides superior elastic deformation capabilities, effective waterproofing, and dustproofing. It reliably protects internal components and base bearings from erosion.
5. Large Displacement and Convenient Selection
Engineered to modular standards, this joint offers displacement ranges from 80 to 1200mm. Such versatility allows bridge design and construction departments to select the most appropriate specification, meeting the precise expansion and contraction requirements of the bridge superstructure.
Telescopic Resistance:
Single-Seam Expansion Joint
1. The compression force during contraction is 0.1KN/m.
2. The longitudinal shear force within the working range of the expansion joint is 2.0KN/m.
Multi-Seam Expansion Joint
1. The compression force during contraction is 0.1KN/m.
2. The tensile force during stretching is 4.0KN/m.
