Product Description
Bridge Expansion Joint, Modular Expansion Joint
Futures:
1. Unyielding Strength and Reliability
The side beams and middle beams of the Suzhou CSXYXC Bridge Railway Expansion Joint are crafted from robust 16Mn steel. This material is designed to endure the vertical loads from heavy traffic and large-tonnage vehicles, along with horizontal impacts. The securely welded anchoring members ensure that the vehicle load is effectively transferred to the abutment, making the structure exceptionally sound and durable. This joint is ideally suited for bridge designs with load capacities exceeding 20 steam and 120 hanging.
2. Precision Expansion Mechanism
The expansion joint features a displacement control system comprising rubber springs, PTFE pressure bearings, or inclined support members. This system ensures uniform displacement with minimal friction, allowing smooth expansion and contraction across all groups.
3. Smooth Deck for Comfortable Travel
This innovative device guarantees the free expansion and contraction of the beam, resulting in a seamless bridge deck. The joints merge into a smooth surface, providing an uninterrupted and comfortable driving experience.
4. Effective Water and Corrosion Resistance
Embedded neoprene rubber sealing strips in the steel beam grooves offer excellent elastic deformation, waterproofing, and dustproof capabilities. These features effectively shield the internal components and bottom bearings of the expansion joints from erosion, ensuring long-term durability.
5. Wide Displacement Range and Easy Selection
Designed with a displacement range from 80mm to 1200mm, this device allows for flexible selection based on the actual expansion and contraction needs of the bridge superstructure, catering to diverse design and construction requirements.
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. The compression force during contraction is 0.1KN/m.
2. The tensile force during stretching is 4.0KN/m.
