Product Description
Delve into the realm of engineering prowess with our Bridge Expansion Joints and Modular Expansion Joints, crafted with precision to conquer the complexities of contemporary infrastructure.
Features:
1. Sturdy and Reliable
Crafted with expertise, the side beams and middle beams of this expansion joint are forged from durable 16Mn steel, epitomizing strength and accuracy. These components are meticulously designed to handle the burdens of heavy, high-traffic vehicles, resisting horizontal shocks. With anchoring elements seamlessly welded to both beams and the bridge deck, vehicle loads are efficiently transferred to the abutment. This meticulous engineering ensures a durable and structurally sound product, ideal for bridges accommodating loads up to steam - over 20, and hanging - 120. A testament to longevity and reliability, it stands as a pillar of modern bridge construction.
2. Sensitive Expansion
Equipped with a sophisticated displacement control system, this device integrates advanced spring elements including rubber springs, PTFE pressure bearings, and inclined support members. These components synergize to maintain consistent displacement and minimize friction during expansion and contraction, thus optimizing group performance.
3. Smooth Bridge Deck and Comfortable Travel
Our device ensures the beams' free expansion and contraction while maintaining a smooth, unified bridge deck surface. This design innovation guarantees a seamless and pleasant driving experience, markedly elevating travel quality.
4. Water Stopping and Corrosion Prevention
Featuring a neoprene rubber sealing strip within each steel beam's groove, this product excels in elastic deformation, providing top-tier waterproofing and dustproofing. It effectively guards the expansion joints and base bearings against erosion, promising durability and unwavering dependability.
5. Large Displacement and Convenient Selection
Engineered with a standard modulus, this device spans a versatile displacement range of 80 to 1200mm. Bridge designers and construction engineers can effortlessly choose the optimal specification based on actual expansion and contraction needs, ensuring precise application and peak performance.
Telescopic Resistance:
Single-Seam Expansion Joint
1. The compression force during contraction is expertly regulated at 0.1KN/m.
2. The longitudinal shear force within the expansion joint's working range is effectively maintained at 2.0KN/m.
Multi-Seam Expansion Joint
1. The compression force during contraction is meticulously calibrated to 0.1KN/m.
2. The tensile force during stretching is robustly controlled at 4.0KN/m.
