Product Description
Bridge Expansion Joints, Modular Expansion Joints
Features:
1. Sturdy and Reliable
The side beams and middle beams of this outstanding expansion joint are meticulously crafted from resilient 16Mn steel. This engineering marvel is designed to not only withstand the vertical load of heavy, high-traffic vehicles but also efficiently manage horizontal impacts. The anchoring components are robustly welded to the beams and bridge deck, ensuring an efficient transfer of loads to the abutment. This precision-engineered design results in a structurally sound and remarkably durable product, perfectly suited for bridges with design loads reaching steam - over 20, and hanging - 120.
2. Sensitive Expansion
Our device's advanced displacement control system incorporates innovative spring elements like rubber springs, PTFE pressure bearings, or inclined support members. This ensures consistent displacement with minimal friction, offering smooth expansion and contraction for each group.
3. Smooth Bridge Deck and Comfortable Travel
This device ensures the beam's free expansion and contraction displacement, maintaining the bridge deck joints in a smooth, unified surface. It guarantees a seamless and comfortable driving experience, significantly enhancing the overall quality of travel.
4. Water Stopping and Corrosion Prevention
Equipped with a neoprene rubber sealing strip embedded snugly within each steel beam group's groove, this product demonstrates exceptional capability in elastic deformation, waterproofing, and dustproofing. It effectively protects the internal components of the expansion joints and the base bearings from erosion, ensuring unparalleled longevity and reliability.
5. Large Displacement and Convenient Selection
Ingeniously designed and manufactured according to a standard modulus, this device offers an expansive displacement range from 80 to 1200mm. Bridge design and construction departments can easily select the appropriate specification tailored to the precise expansion and contraction requirements of the bridge superstructure, guaranteeing precise application and optimal performance.
Telescopic Resistance:
Single-Seam Expansion Joint
1. The compression force during contraction is a minimal 0.1KN/m.
2. The longitudinal shear force within the working range of the expansion joint is efficiently maintained at 2.0KN/m.
Multi-Seam Expansion Joint
1. The compression force during contraction is precisely measured at 0.1KN/m.
2. The tensile force during stretching is an impressive 4.0KN/m.
