Product Description
Bridge Expansion Joints, Modular Expansion Joints
Features:
1. Sturdy and Reliable
Our expansion joint exemplifies superior craftsmanship, featuring side and middle beams crafted from resilient 16Mn steel. This robust construction is meticulously engineered to endure immense vertical loads from high-traffic, heavy-tonnage vehicles and lateral impacts. The welding of the anchoring components to both beams and the bridge deck guarantees efficient load transfer to the abutment. This ensures a structurally sound and durable product, perfectly suited for bridges with design loads exceeding 20-ton steam and accommodating up to 120-ton hanging loads.
2. Sensitive Expansion
The displacement control system in this innovative device incorporates sophisticated spring elements such as rubber springs, PTFE pressure bearings, or inclined support members. This advanced design ensures uniform displacement and minimal friction, facilitating smooth and efficient expansion and contraction within each group.
3. Smooth Bridge Deck and Comfortable Travel
Our cutting-edge design ensures that the beam expands and contracts effortlessly while maintaining a smooth and unified bridge deck surface. This guarantees a seamless and comfortable driving experience for all users.
4. Water Stopping and Corrosion Prevention
Equipped with a neoprene rubber sealing strip embedded in the groove of each steel beam group, this expansion joint offers superior elastic deformation capabilities, waterproofing, and dustproofing. It effectively protects internal components and base bearings from erosion and environmental damage.
5. Large Displacement and Convenient Selection
Designed and manufactured according to modular standards, this device provides displacement ranges from 80 to 1200mm. This extensive flexibility allows bridge design and construction departments to choose the appropriate specification, accommodating the actual expansion and contraction needs of the bridge superstructure with ease.
Telescopic Resistance:
