Product Description
Bridge Expansion Joint, Modular Expansion Joint
Features:
1. Sturdy and Reliable
The side beams and middle beams of this exceptional expansion joint are crafted from robust rolled 16Mn steel. This design ensures it can withstand the vertical loads from high traffic and large tonnage vehicles as well as horizontal impacts. Its anchoring members, firmly welded to the embedded steel in the bridge deck, reliably transfer vehicle loads to the abutment. Structurally sound and durable, it is ideal for bridges with a design load over 20 tons for steam and 120 tons for hanging.
2. Sensitive Expansion
This innovative device features a displacement control system comprising spring elements such as rubber springs, PTFE pressure bearings, or inclined support members. It ensures uniform displacement with minimal friction during expansion and contraction in each group.
3. Smooth Bridge Deck, Comfortable Traveling
Our device guarantees free expansion and contraction of the beam while forming a smooth, seamless bridge deck joint. This leads to a smooth and comfortable driving experience.
4. Water Resistance and Corrosion Prevention
Embedded within the groove of each steel beam group is a neoprene rubber sealing strip. This strip, processed according to the bridge width, offers excellent elastic deformation, waterproof, and dustproof capabilities. It effectively protects the internal components of the expansion joint and the bearing at the bridge bottom from erosion.
5. Large Displacement, Convenient Selection
Designed and manufactured according to the modulus, the displacement range of this device spans from 80 to 1200mm. This flexibility allows bridge design and construction departments to select the most suitable option based on 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. 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.
