Product Description
Bridge Expansion Joints, Modular Expansion Joints
Features:
1. Sturdy and Reliable
The side beams and middle beams of this premium expansion joint are meticulously crafted from high-grade 16Mn steel. This superior design allows the joint to withstand the immense vertical loads of heavy-traffic and high-tonnage vehicles, along with horizontal impacts. The anchoring components are securely welded to both the beams and the bridge deck, ensuring that vehicle loads are efficiently transferred to the abutment. This results in an exceptionally robust and durable product, ideal for bridges with design loads of steam - over 20, and hanging - 120.
2. Sensitive Expansion
This advanced device integrates a sophisticated displacement control system with spring elements, including rubber springs, PTFE pressure bearings, or inclined support members. It ensures uniform displacement and minimizes friction during expansion and contraction, maintaining optimal performance across each group.
3. Smooth Bridge Deck and Comfortable Travel
Our state-of-the-art device guarantees free expansion and contraction displacement of the beam, ensuring that the bridge deck joints form a smooth, unified surface. This design delivers a seamless and comfortable driving experience for all users.
4. Water Stopping and Corrosion Prevention
Equipped with a high-quality neoprene rubber sealing strip embedded in the groove of each steel beam group, this product provides outstanding elastic deformation, waterproof, and dustproof capabilities. It effectively protects the internal components of the expansion joints and the base bearings from erosion and wear.
5. Large Displacement and Convenient Selection
Engineered and manufactured according to a precise modulus, this device offers a wide range of displacements from 80 to 1200mm. Design and construction departments can freely choose the appropriate specification based on the actual expansion and contraction requirements of the bridge superstructure, ensuring versatility and ease of selection.
Telescopic Resistance:
Single-Seam Expansion Joint
1. The compression force during contraction is precisely 0.1KN/m.
2. The longitudinal shear force within the working range of the expansion joint is consistently 2.0KN/m.
Multi-Seam Expansion Joint
1. The compression force during contraction is reliably 0.1KN/m.
2. The tensile force during stretching is an impressive 4.0KN/m.
