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 crafted from high-strength 16Mn steel. This exceptional material is specifically chosen to withstand the rigorous demands of high-traffic, heavy-tonnage vehicles, as well as the horizontal impacts they generate. The anchoring components are expertly welded to ensure a steadfast connection between the beams and the bridge deck. This ensures that vehicle loads are reliably transferred to the abutment, resulting in a structurally sound and extraordinarily durable product. It is perfectly suited for bridges with design loads of steam - over 20, and hanging - 120.
2. Sensitive Expansion
The displacement control system of this device ingeniously integrates spring elements such as rubber springs, PTFE pressure bearings, or inclined support members. This advanced system ensures uniform displacement and minimizes friction during both the expansion and contraction phases within each group.
3. Smooth Bridge Deck and Comfortable Travel
Our state-of-the-art device not only guarantees the free and unhindered expansion and contraction of the beam but also ensures that the bridge deck joints form a seamlessly smooth and unified surface. This provides drivers with an unparalleled, comfortable driving experience.
4. Water Stopping and Corrosion Prevention
Featuring a neoprene rubber sealing strip embedded in the groove of each steel beam group, this product offers superior elastic deformation, waterproof, and dustproof capabilities. It effectively safeguards the internal components of the expansion joints and the base bearings from any erosive elements.
5. Large Displacement and Convenient Selection
Designed and manufactured according to a precise modulus, this device offers expansive displacements ranging from 80 to 1200mm. This allows bridge design and construction departments the flexibility to select the appropriate specification based on the exact expansion and contraction needs of the bridge superstructure.
Telescopic Resistance:
Single-Seam Expansion Joint
1. The compression force during contraction is precisely measured at 0.1KN/m.
2. The longitudinal shear force within the working range of the expansion joint is efficiently managed at 2.0KN/m.
Multi-Seam Expansion Joint
1. The compression force during contraction is consistently maintained at 0.1KN/m.
2. The tensile force during stretching is robustly supported at 4.0KN/m.
