Product Description
Introducing the Bridge Expansion Joint and Modular Expansion Joint
Key Features:
1. Robust and Dependable Construction
Crafted from premium rolled 16Mn steel, the side and middle beams of this expansion joint are engineered to endure the vertical and horizontal stresses from high-traffic, heavy-load vehicles. Securely welded anchoring components ensure that loads are efficiently transferred to the abutment. This results in a structure that is not only durable but also reliable under the design load specifications of steam - over 20, and hanging - 120 for bridges.
2. Highly Responsive Expansion Mechanism
This device's displacement control system utilizes advanced elements such as rubber springs, PTFE pressure bearings, and inclined support members. These components work together seamlessly to guarantee uniform displacement and minimal friction during expansion and contraction phases.
3. Smooth Deck Surface for Comfortable Transit
Engineered for superior performance, this device allows for the free expansion and contraction of the beam, ensuring that bridge deck joints form a cohesive, smooth surface. This results in a driving experience that is both smooth and comfortable.
4. Superior Water Resistance and Corrosion Protection
Equipped with a neoprene rubber sealing strip embedded in the groove of each steel beam group, this device offers excellent elastic deformation and waterproof capabilities. Effectively, it protects internal expansion joint components and the bearing from corrosion, extending the lifespan and reliability of the joint.
5. Versatile and Large Displacement Range
Designed and manufactured according to modulus specifications, this device covers a displacement range from 80 to 1200mm. This allows bridge design and construction teams the flexibility to select the appropriate joint based on the specific 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.
