Product Description
Bridge Expansion Joints, Modular Expansion Joints
Features:
1. Sturdy and Reliable
The side beams and middle beams of this expansion joint are meticulously engineered from resilient 16Mn steel. This robust construction is designed to withstand the vertical loads of high-traffic, heavy-tonnage vehicles and absorb horizontal impacts efficiently. The anchoring components are expertly welded to both the beams and the bridge deck, ensuring a seamless transfer of vehicle loads to the abutment. This results in a structurally sound and long-lasting product, ideal for bridges with design loads of steam over 20 and hanging up to 120.
2. Sensitive Expansion
This advanced displacement control system incorporates spring elements such as rubber springs, PTFE pressure bearings, or inclined support members. It ensures uniform displacement and minimizes friction during expansion and contraction, providing smooth operation within each group.
3. Smooth Bridge Deck and Comfortable Travel
Our innovative device not only guarantees free expansion and contraction displacement of the beam but also ensures that the bridge deck joints create a smooth, cohesive surface. This delivers a seamless and comfortable driving experience.
4. Water Stopping and Corrosion Prevention
Featuring a neoprene rubber sealing strip embedded within the groove of each steel beam group, this product excels in elastic deformation, waterproofing, and dustproofing. It effectively safeguards the internal components of the expansion joints and the base bearings from erosion.
5. Large Displacement and Convenient Selection
Engineered and manufactured according to a precise modulus, this device offers displacement options ranging from 80 to 1200mm. Bridge design and construction professionals can easily select the appropriate specification to meet the actual expansion and contraction demands of the bridge superstructure.
Telescopic Resistance:
Single-Seam Expansion Joint
1. The compression force during contraction is 0.1 KN/m.
2. The longitudinal shear force within the working range of the expansion joint is 2.0 KN/m.
Multi-Seam Expansion Joint
1. The compression force during contraction is 0.1 KN/m.
2. The tensile force during stretching is 4.0 KN/m.
