Product Description
Bridge Expansion Joint, Modular Expansion Joint
Features:
1. Sturdy and Reliable
The side beams and middle beams of this expansion joint are crafted from high-strength rolled 16Mn steel. This robust construction supports the heavy vertical loads of high-traffic, large-tonnage vehicles, while also withstanding significant horizontal impacts. The securely welded anchoring members seamlessly transfer vehicle loads to the abutment, ensuring exceptional structural integrity and durability. Suitable for bridges designed to handle steam loads over 20 and hanging loads up to 120.
2. Sensitive Expansion
Equipped with a sophisticated displacement control system, this device incorporates elements such as rubber springs, PTFE pressure bearings, and inclined support members. The result is a uniform displacement with minimal friction during expansion and contraction, ensuring reliable performance across each group.
3. Smooth Bridge Deck, Comfortable Traveling
This innovative device ensures the beam's free expansion and contraction, resulting in seamless bridge deck joints that provide smooth and comfortable traveling conditions for all vehicles.
4. Water Stopping and Corrosion Prevention
Embedded with high-quality neoprene rubber sealing strips within each steel beam groove, this device offers excellent elastic deformation properties. It effectively provides waterproof and dustproof capabilities, safeguarding internal components and bottom bearings from corrosion and external damage.
5. Large Displacement, Convenient Selection
Designed and manufactured based on a modular approach, this device supports displacements ranging from 80mm to 1200mm. Bridge design and construction departments have the flexibility to select according to the actual expansion and contraction requirements of the bridge superstructure.
Telescopic Resistance:
Single-seam Expansion Joint
1. The compression force is 0.1KN/m during contraction.
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 when stretching is 4.0KN/m.
