Product Description
Bridge Expansion Joint, Modular Expansion Joint
Features:
1. Sturdy and Reliable
The side beams and middle beams of this advanced expansion joint are crafted from robust rolled 16Mn steel. This material is engineered to withstand the vertical loads of high-traffic, heavy-tonnage vehicles, as well as horizontal impacts. The anchoring members, seamlessly welded to the beam and bridge deck, ensure that the vehicle load is efficiently transferred to the abutment. This construction provides unmatched structural integrity and longevity, ideal for bridge designs accommodating steam loads over 20 and hanging loads of up to 120.
2. Sensitive Expansion
This sophisticated device features a displacement control system incorporating elements like rubber springs, PTFE pressure bearings, or inclined support members. It ensures uniform displacement with minimal friction during expansion and contraction, providing reliable performance in every scenario.
3. Smooth Bridge Deck, Comfortable Travel
Designed to facilitate seamless bridge deck joints, this device allows for the free expansion and contraction displacement of the beam. This results in an unbroken, smooth driving surface, offering unparalleled comfort during travel.
4. Water Stopping and Corrosion Prevention
Each group of steel beams features an embedded neoprene rubber sealing strip. This is precisely processed to match the bridge width, providing excellent elastic deformation, waterproofing, and dustproofing capabilities. These features effectively protect the internal components of the expansion joints and the bearing from corrosive elements.
5. Large Displacement, Convenient Selection
Designed with variable displacement capabilities ranging from 80 to 1200mm, this device allows bridge design and construction teams to select the appropriate expansion and contraction levels based on the specific requirements of the bridge superstructure.
Telescopic Resistance:
Single-seam Expansion Joint
1. It exhibits a compression force of 0.1KN/m during contraction.
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 measures 0.1KN/m.
2. The tensile force during stretching reaches 4.0KN/m.
