Product Description
Bridge Expansion Joints, Modular Expansion Joints
Features:
1. Sturdy and Reliable
Our expansion joint stands out with its impeccable craftsmanship, featuring side and middle beams forged from resilient 16Mn steel. This robust construction is tailored to endure immense vertical loads from high-traffic, heavy-tonnage vehicles and lateral impacts. The precision welding of anchoring components to both the beams and the bridge deck facilitates efficient load transfer to the abutment. This ensures a structurally sound, long-lasting product, perfect for bridges designed to handle steam loads exceeding 20 and hangings up to 120.
2. Sensitive Expansion
The innovative displacement control system of this device integrates cutting-edge spring elements such as rubber springs, PTFE pressure bearings, or inclined support members. This sophisticated design promises uniform displacement and reduced friction, guaranteeing smooth and seamless expansion and contraction within each group.
3. Smooth Bridge Deck and Comfortable Travel
Our state-of-the-art design allows the beam to expand and contract effortlessly while preserving a smooth, cohesive bridge deck surface, ensuring a seamless and comfortable driving experience for all users.
4. Water Stopping and Corrosion Prevention
This expansion joint comes equipped with a high-performance neoprene rubber sealing strip, embedded within the groove of each steel beam group. This provides exceptional elastic deformation capabilities, along with superior waterproofing and dustproofing, effectively protecting internal components and base bearings from corrosive elements.
5. Large Displacement and Convenient Selection
Engineered to modular standards, this device offers displacement ranges from 80 to 1200mm. This adaptability allows bridge design and construction teams to select the ideal specification, catering to the actual expansion and contraction demands of the bridge superstructure.
Telescopic Resistance:
Single-Seam Expansion Joint
1. The compression force during contraction is meticulously maintained at 0.1KN/m.
2. The longitudinal shear force within the functional range of the expansion joint is precisely 2.0KN/m.
Multi-Seam Expansion Joint
1. The compression force during contraction is precisely regulated at 0.1KN/m.
2. The tensile force during stretching is accurately measured at 4.0KN/m.
