Product Description
Bridge Expansion Joints, Modular Expansion Joints
Features:
1. Sturdy and Reliable
The side beams and middle beams of this expansion joint are meticulously crafted from durable 16Mn steel. They are engineered to withstand the vertical loads of high-traffic and heavy-tonnage vehicles, as well as horizontal impacts. The anchoring components are securely welded to both the beams and the bridge deck, ensuring reliable load transfer to the abutment. This results in a structurally sound, durable product, perfect for bridges designed for steam loads over 20 and hanging loads up to 120.
2. Sensitive Expansion
Our device's displacement control system features advanced spring elements such as rubber springs, PTFE pressure bearings, or inclined support members. This ensures uniform displacement and minimal friction during expansion and contraction, providing precise, reliable performance.
3. Smooth Bridge Deck and Comfortable Travel
This device guarantees not only free expansion and contraction of the beam but also ensures that bridge deck joints form a smooth, unified surface. The result is a seamless and comfortable driving experience.
4. Water Stopping and Corrosion Prevention
Equipped with a high-quality neoprene rubber sealing strip embedded in the groove of each steel beam group, this product offers superior elastic deformation capabilities, along with excellent waterproof and dustproof functionalities. It effectively protects the internal components of the expansion joints and the base bearings from erosion.
5. Large Displacement and Convenient Selection
Designed and manufactured according to a precise modulus, this device offers displacements ranging from 80 to 1200mm. Bridge design and construction departments can easily select the appropriate specification based on the actual expansion and contraction requirements of the bridge superstructure.
Telescopic Resistance:
Single-Seam Expansion Joint
1. The compression force during contraction is 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 0.1KN/m.
2. The tensile force during stretching is 4.0KN/m.
