Product Description
Bridge Expansion Joint, Modular Expansion Joint
Features:
1. Sturdy and Reliable
Crafted from robust 16Mn steel, the side beams and middle beams of this expansion joint are engineered to endure heavy vertical loads and substantial horizontal impacts. The anchoring components are firmly welded to the bridge deck, ensuring reliable load transfer to the abutment. This results in a structurally sound and durable system, ideal for bridges designed to handle steam loads over 20 and hanging loads up to 120.
2. Sensitive Expansion
The displacement control system integrates spring elements like rubber springs, PTFE pressure bearings, or inclined support members. This ensures uniform displacement and minimal friction during expansion and contraction, providing smooth and efficient performance.
3. Smooth Bridge Deck, Comfortable Traveling
This device guarantees the free expansion and contraction of the beam while maintaining a seamless bridge deck. This ensures a smooth and comfortable driving experience for motorists.
4. Water Stopping and Corrosion Prevention
Each steel beam group is embedded with a neoprene rubber sealing strip, providing excellent elastic deformation, waterproofing, and dustproofing. This protects the internal components of the expansion joints and the bottom bearing from erosion, ensuring longevity and performance.
5. Large Displacement, Convenient Selection
Designed with a displacement range from 80 to 1200mm, this device allows bridge design and construction departments to select the appropriate model based on the actual expansion and contraction needs of the bridge superstructure.
Telescopic Resistance:
Single-Seam Expansion Joint
1. Compression force during contraction is 0.1KN/m.
2. Longitudinal shear force within the working range 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.
