Product Description
Bridge Expansion Joints, Modular Expansion Joints
Features:
1. Sturdy and Reliable
Crafted from high-strength 16Mn steel, the side beams and middle beams of our expansion joint are designed to withstand the vertical loads of high-traffic, heavy-tonnage vehicles, as well as horizontal impacts. The anchoring components are securely welded to both the beams and the bridge deck, ensuring reliable transfer of vehicle loads to the abutment. This results in a structurally sound and durable product, ideal for bridges with design loads of steam - over 20, and hanging - 120.
2. Sensitive Expansion
Our displacement control system integrates spring elements such as rubber springs, PTFE pressure bearings, or inclined support members. This ensures uniform displacement and low friction during expansion and contraction within each group, providing a smooth and efficient performance.
3. Smooth Bridge Deck and Comfortable Travel
Our device guarantees not only the free expansion and contraction displacement of the beam but also ensures a smooth, unified surface for the bridge deck joints. This results in a seamless and comfortable driving experience for all vehicles.
4. Water Stopping and Corrosion Prevention
Equipped with a neoprene rubber sealing strip embedded in the groove of each steel beam group, our product offers excellent elastic deformation, waterproofing, and dustproofing capabilities. It effectively protects the internal components of the expansion joints and the base bearings from erosion, ensuring longevity and performance.
5. Large Displacement and Convenient Selection
Designed and manufactured according to a modulus, our device offers displacements ranging from 80 to 1200mm. This allows bridge design and construction departments the freedom to select the appropriate specification based on the actual expansion and contraction requirements 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 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.
