Product Description
Bridge Expansion Joint, Modular Expansion Joint
Features:
1. Sturdy and Reliable
The side beams and middle beams of this expansion joint are engineered with high-quality 16Mn rolled steel, capable of withstanding the vertical load of high traffic volume and heavy tonnage vehicles, as well as significant horizontal impacts. The components are firmly embedded within the bridge deck and securely welded, ensuring load transfer to the abutment with structural soundness and durability. Designed for steam load over 20 and hanging load up to 120 of the bridge.
2. Sensitive Expansion
This device features a sophisticated displacement control system, incorporating elements such as rubber springs, PTFE pressure bearings, or inclined support members. This ensures uniform displacement with minimal friction during expansion and contraction.
3. Smooth Bridge Deck, Comfortable Traveling
Our innovative design guarantees the unobstructed expansion and contraction displacement of the beam. It ensures that the bridge deck joints form a seamless surface, providing a smooth and comfortable driving experience.
4. Water Stopping and Corrosion Prevention
Each group of steel beams is fitted with neoprene rubber sealing strips, processed in accordance with the bridge width. These strips offer excellent elastic deformation, waterproof, and dustproof capabilities, effectively protecting the internal components and bottom bearings from corrosion.
5. Large Displacement, Convenient Selection
This device is designed with displacement ranges from 80 to 1200mm, based on modular design principles. Bridge design and construction teams can easily select the appropriate specifications to accommodate the actual expansion and contraction requirements 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.
