Product Description
Bridge Expansion Joints, Modular Expansion Joints
Features:
1. Sturdy and Reliable
Our High-Performance Rubber Joint is masterfully constructed with side and middle beams forged from resilient 16Mn steel. This design is adept at withstanding the rigorous demands of heavy and high-volume traffic, efficiently absorbing vertical loads and horizontal shocks. The meticulously welded anchoring components seamlessly integrate with the beams and bridge deck, ensuring flawless load transition to the abutment. This unparalleled attention to detail ensures not just exceptional structural integrity but also unmatched durability, making it the ideal choice for bridges engineered to support significant loads - up to steam - over 20, and hanging - 120.
2. Sensitive Expansion
Equipped with an advanced displacement control system, this device harnesses the power of spring components, including rubber springs, PTFE pressure bearings, and inclined supports, to ensure uniform displacement. This system significantly reduces friction during expansion and contraction, allowing for seamless coordination across all groups and maintaining the structural harmony of the joint.
3. Smooth Bridge Deck and Comfortable Travel
Our expertly engineered expansion joint enables the beams to expand and contract smoothly, creating a harmonious and uniform bridge deck. This ensures not only a smooth and uninterrupted driving experience but also enhances the overall quality of travel, providing unparalleled comfort for road users.
4. Water Stopping and Corrosion Prevention
This innovative product features a neoprene rubber sealing strip, expertly embedded within each steel beam groove. This provides exceptional capabilities in elastic deformation, waterproofing, and dustproofing, thereby safeguarding the internal components and base bearings of the expansion joints from corrosion and erosion, thus ensuring long-term reliability and durability.
5. Large Displacement and Convenient Selection
Designed to align with standard modulus specifications, this device offers a wide displacement range from 80 to 1200mm. This allows bridge design and construction professionals the flexibility to select the most appropriate specification based on the actual expansion and contraction needs of the bridge, ensuring precise application and optimal performance tailored to specific project requirements.
Telescopic Resistance:
Single-Seam Expansion Joint
1. During contraction, the compression force is precisely engineered to be 0.1KN/m, ensuring optimal performance and efficiency.
2. The longitudinal shear force, within the operational range of the expansion joint, is meticulously set at 2.0KN/m, providing robust resistance and durability.
Multi-Seam Expansion Joint
1. The compression force during contraction is expertly controlled at 0.1KN/m, guaranteeing consistent performance.
2. The tensile force during stretching is robustly calibrated at 4.0KN/m, ensuring enhanced structural integrity and reliability.
