Exquisite Product Overview:
Bridge Expansion Joint: Unveiling the Modular Expansion Joint
Outstanding Features:
1. Robust and Dependable
Crafted from premium 16Mn rolled steel, the side beams and middle beams of our expansion joint are built to endure the vertical loads of heavy traffic and substantial tonnage, along with lateral impacts. The anchoring components, securely welded to the bridge deck's embedded steel, ensure that vehicular load is reliably transferred to the abutment. This structurally sound and durable joint is impeccably designed for bridge loads exceeding steam - over 20, hanging - 120.
2. Responsive Expansion
Our advanced displacement control system, featuring spring elements like rubber springs, PTFE pressure bearings, or inclined support members, ensures uniform displacement and minimal friction during expansion and contraction across each group.
3. Seamless Bridge Deck for Comfort
This ingenious device facilitates free expansion and contraction of the beam, while simultaneously creating a smooth, uninterrupted bridge deck joint for an exceptionally comfortable driving experience.
4. Effective Water Stopping and Corrosion Resistance
Equipped with a neoprene rubber sealing strip embedded in the groove of each steel beam group, this system, tailored to the bridge's width, boasts excellent elastic deformation, waterproofing, and dustproofing capabilities. It effectively shields the internal components of the expansion joints and base bearings from corrosive elements.
5. Versatile Displacement, Easy Selection
Designed with modular flexibility, the displacement range of this device spans from 80 to 1200mm. Bridge designers and construction professionals can choose the appropriate configuration according to the actual expansion and contraction demands of the bridge superstructure.
Exceptional Telescopic Resistance:
Single-Seam Expansion Joint Specifications:
1. Compression force during contraction: 0.1 KN/m.
2. Longitudinal shear force within the operational range: 2.0 KN/m.
Multi-Seam Expansion Joint Specifications:
1. Compression force during contraction: 0.1 KN/m
2. Tensile force during stretching: 4.0 KN/m
