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 premium rolled 16Mn steel. This ensures exceptional durability to withstand the vertical loads of heavy traffic and the horizontal impacts they bring. Anchoring members are firmly welded to the beams and the embedded steel of the bridge deck, ensuring that vehicle loads are reliably transferred to the abutment. This robust and durable structure is suitable for bridges designed to handle steam loads over 20 and hanging loads up to 120.
2, Sensitive Expansion
This device's displacement control system is composed of sophisticated spring elements such as rubber springs, PTFE pressure bearings, or inclined support members. It offers consistent displacement with minimal friction, ensuring smooth expansion and contraction across all groups.
3, Smooth Bridge Deck, Comfortable Traveling
This device not only guarantees the free expansion and contraction of the beam, but also ensures that the bridge deck joints are seamlessly integrated into a smooth, cohesive whole. This results in a smoother, more comfortable driving experience.
4, Water Stopping and Corrosion Prevention
Each steel beam group features a neoprene rubber sealing strip embedded in the groove. This component, tailored to the bridge's width, provides excellent elastic deformation, waterproofing, and dustproof properties. It effectively protects the internal components of the expansion joints and the bottom bearing from erosion.
5, Large Displacement, Convenient Selection
The displacement of this device is designed with a range of 80 to 1200mm modulus, allowing bridge design and construction teams to select the appropriate model based on the actual expansion and contraction needs 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, Compression force during contraction is 0.1KN/m.
2, Tensile force during stretching is 4.0KN/m.
