Product Description
Bridge Expansion Joint, Modular Expansion Joint
Features:
1. Sturdy and Reliable
Crafted from rolled 16Mn steel, the side and middle beams of this expansion joint can withstand the vertical load of high-traffic, heavy-tonnage vehicles and horizontal impacts. Its anchoring members are firmly welded to the bridge deck's embedded steel, ensuring reliable load transfer to the abutment. This structure is robust, durable, and suitable for bridges designed for loads of steam - over 20, and hanging - 120.
2. Sensitive Expansion
The displacement control system integrates spring elements like rubber springs, PTFE pressure bearings, or inclined support members. This system ensures uniform displacement and minimal friction during expansion and contraction within each group.
3. Smooth Bridge Deck, Comfortable Traveling
This device guarantees the free expansion and contraction displacement of the beam, creating smooth and seamless bridge deck joints for a comfortable driving experience.
4. Water Stopping and Corrosion Prevention
The neoprene rubber sealing strip embedded in the groove of each steel beam group offers excellent elastic deformation, waterproof, and dustproof capabilities. This feature effectively protects the internal components of the expansion joints and the bottom bearing from corrosion.
5. Large Displacement, Convenient Selection
Designed and manufactured according to modulus, this device accommodates displacements ranging from 80 to 1200mm. Bridge design and construction departments can select based on the actual expansion and contraction needs 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.
