Product Description
Bridge Expansion Joint, Modular Expansion Joint
Features:
1. Sturdy and reliable
Crafted from premium rolled 16Mn steel, our expansion joint's side beams and middle beams are engineered to endure immense vertical loads from high-traffic and heavy-tonnage vehicles, as well as horizontal impacts. The anchoring components are securely welded to the bridge deck's embedded steel, ensuring the vehicle load is effectively transferred to the abutment. This results in a structurally sound and durable solution suitable for bridges designed to bear loads exceeding steam-20 and hanging-120.
2. Sensitive expansion
Our device's displacement control system features spring elements like rubber springs, PTFE pressure bearings, and inclined support members. This sophisticated system ensures uniform displacement and minimal friction during expansion and contraction.
3. Smooth bridge deck, comfortable traveling
Designed to facilitate seamless expansion and contraction of the beam, this device guarantees a smooth and continuous bridge deck surface, ensuring a comfortable driving experience.
4. Water stopping and corrosion prevention
Equipped with a neoprene rubber sealing strip embedded in the steel beams' groove, this product offers excellent elastic deformation, watertight, and dustproof capabilities. It effectively shields the internal components and bottom bearings from erosion, enhancing longevity.
5. Large displacement, convenient selection
Engineered with a displacement range from 80mm to 1200mm, this device allows bridge design and construction teams to select the optimal size 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. 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. The tensile force when stretching is 4.0KN/m.
