Exquisite Product Description
Innovative Bridge Expansion Joint, Modular Expansion Joint Solutions
Remarkable Features:
1. Sturdiness and Reliability
The side beams and middle beams of this advanced expansion joint are meticulously crafted from high-grade 16Mn steel. This ensures exceptional resistance to the vertical load of heavy traffic and horizontal impact. The anchoring members are seamlessly welded to the steel of the bridge deck, effectively transferring the vehicle load to the abutment. This results in a structurally sound and durable system, perfectly suited for design load steam over 20 and hanging load up to 120 for bridges.
2. Sensitive Expansion Mechanism
The displacement control system of this innovative device features spring elements such as rubber springs, PTFE pressure bearings, or inclined support members. This setup ensures uniform displacement and low friction during expansion and contraction, offering a highly responsive system.
3. Smooth Bridge Deck for Comfortable Travel
This device not only accommodates free expansion and contraction displacement of the beams but also ensures that the bridge deck joints form a seamless surface. This guarantees a smooth and comfortable driving experience.
4. Effective Water Stopping and Corrosion Prevention
Each group of embedded steel beams features a neoprene rubber sealing strip, which is processed according to the bridge width. This provides excellent elastic deformation capabilities, along with waterproof and dustproof functions. It effectively protects the internal components of the expansion joints and the underlying bearing from erosion.
5. Large Displacement and Convenient Selection
Designed according to a precise modulus ranging from 80 to 1200mm, this device allows bridge design and construction departments to select the most suitable option based on the actual expansion and contraction needs of the bridge superstructure.
Telescopic Resistance Specifications:
Single-Seam Expansion Joint
1. During contraction, the compression force is maintained at 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 regulated at 0.1KN/m.
2. When stretching, the tensile force reaches 4.0KN/m.
