Magnificent Product Description
Bridge Expansion Joints, Modular Expansion Joints
Outstanding Features:
1. Sturdy and Reliable
Our expansion joint showcases unparalleled craftsmanship, featuring side and middle beams forged from robust 16Mn steel. This design ensures remarkable endurance against immense vertical loads from high-traffic, heavy-tonnage vehicles, as well as lateral impacts. The welding of anchoring components to both beams and the bridge deck guarantees efficient transfer of vehicle loads to the abutment, resulting in a structurally sound and enduring product. It is the quintessential choice for bridges with design loads surpassing 20 and hanging up to 120.
2. Sensitive Expansion
The displacement control system in this device incorporates cutting-edge spring elements such as rubber springs, PTFE pressure bearings, and inclined support members. This innovative design ensures uniform displacement and minimal friction, facilitating smooth expansion and contraction within each group.
3. Smooth Bridge Deck and Comfortable Travel
Our sophisticated design permits the beam to expand and contract freely while maintaining a smooth, seamless bridge deck surface. This results in an unparalleled, comfortable driving experience.
4. Water Stopping and Corrosion Prevention
Equipped with a high-quality neoprene rubber sealing strip embedded within the groove of each steel beam group, this expansion joint provides superior elastic deformation capabilities. It offers exceptional waterproofing and dustproofing, effectively shielding internal components and base bearings from any form of erosion.
5. Large Displacement and Convenient Selection
Engineered according to modular standards, this device accommodates displacement ranges from 80mm to an impressive 1200mm. This flexibility allows bridge design and construction departments to select the appropriate specification, meeting the actual expansion and contraction needs of the bridge superstructure with precision.
Telescopic Resistance:
Single-Seam Expansion Joint
1. The compression force during contraction is precisely 0.1KN/m.
2. The longitudinal shear force within the working range of the expansion joint is an impressive 2.0KN/m.
Multi-Seam Expansion Joint
1. The compression force during contraction remains at 0.1KN/m.
2. The tensile force during stretching reaches a substantial 4.0KN/m.
