Product Description
Bridge Expansion Joints, Modular Expansion Joints
Features:
1. Sturdy and Reliable
Our expansion joint epitomizes superior craftsmanship. Constructed with robust 16Mn steel for side and middle beams, it is engineered to withstand colossal vertical loads and lateral impacts from high-traffic, heavy-tonnage vehicles. The anchoring components are meticulously welded to both the beams and the bridge deck, ensuring the efficient transfer of vehicle loads to the abutment. This meticulous engineering results in a structurally sound, durable product, perfectly suited for bridges with design loads exceeding 20 and accommodating hanging loads up to 120.
2. Sensitive Expansion
Our displacement control system incorporates state-of-the-art spring elements such as rubber springs, PTFE pressure bearings, and inclined support members. This sophisticated design ensures uniform displacement and minimal friction, providing seamless and efficient expansion and contraction across every group.
3. Smooth Bridge Deck and Comfortable Travel
Our cutting-edge design facilitates the free expansion and contraction of the beam while maintaining a seamless, unified bridge deck surface. This ensures an uninterrupted, comfortable driving experience for all vehicles.
4. Water Stopping and Corrosion Prevention
This expansion joint features a neoprene rubber sealing strip embedded within the groove of each steel beam group. This provides exceptional elastic deformation capabilities, along with waterproofing and dustproofing properties. It effectively protects internal components and base bearings from erosion, ensuring longevity and enhanced performance.
5. Large Displacement and Convenient Selection
Manufactured to modular standards, this expansion joint offers displacement ranges from 80 to 1200mm. This flexibility enables bridge design and construction departments to select the most appropriate specifications, perfectly aligning with 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. The longitudinal shear force within the working range of the expansion joint is 2.0KN/m.
Multi-Seam Expansion Joint
1. The compression force during contraction is 0.1KN/m.
2. The tensile force during stretching is 4.0KN/m.
