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-quality 16Mn rolled steel, capable of withstanding the vertical load of high-traffic, heavy-tonnage vehicles, as well as horizontal impacts. The anchoring members, firmly welded to the bridge deck and beams, reliably transfer vehicle loads to the abutment, ensuring structural integrity and durability. This joint is designed for load capacities of steam - over 20, and hanging - 120, making it ideal for robust bridge applications.
2. Sensitive Expansion
The displacement control system features spring elements such as rubber springs, PTFE pressure bearings, or inclined support members. This configuration ensures uniform displacement and minimizes friction during expansion and contraction, delivering a smooth and precise performance in each group.
3. Smooth Bridge Deck, Comfortable Traveling
This device not only accommodates free expansion and contraction of the beams but also ensures that the bridge deck joints form a seamless and smooth surface, providing a comfortable driving experience.
4. Water Stopping and Corrosion Prevention
Embedded neoprene rubber sealing strips in the grooves of each steel beam group offer excellent elastic deformation, waterproof, and dustproof capabilities. These features protect the internal components of the expansion joints and the sorghum bottom bearings from erosion, extending the product's lifespan.
5. Large Displacement, Convenient Selection
The displacement ranges from 80 to 1200mm and is designed according to modular standards. This flexibility allows bridge design and construction departments to select the appropriate configuration based on 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.
