Product Description
Bridge Expansion Joints, Modular Expansion Joints
Features:
1. Sturdy and Reliable
Our premier expansion joint is a symbol of superior engineering craftsmanship. Forged from durable 16Mn steel, both the side and middle beams are meticulously engineered to withstand substantial vertical loads from heavy traffic and massive vehicles, as well as intense lateral impacts. Precision-welded anchoring components ensure seamless load transfer to the abutment, securing a structurally stable and enduring solution, ideal for bridges designed to handle loads surpassing 20 steam and supporting hanging capacities up to 120.
2. Sensitive Expansion
The device integrates an advanced displacement control system incorporating cutting-edge spring elements such as rubber springs, PTFE pressure bearings, and inclined support members. This innovative design guarantees uniform displacement and minimizes friction, enabling smooth and reliable expansion and contraction within each group.
3. Smooth Bridge Deck and Comfortable Travel
Our state-of-the-art design promotes the free expansion and contraction of the beam while preserving a smooth, continuous bridge deck surface. This ensures a seamless and comfortable driving experience, significantly enhancing overall travel quality.
4. Water Stopping and Corrosion Prevention
Fitted with a neoprene rubber sealing strip securely embedded in the groove of each steel beam group, this expansion joint delivers exceptional elastic deformation capabilities. It provides reliable waterproofing and dustproofing, effectively shielding internal components and base bearings from erosion.
5. Large Displacement and Convenient Selection
Engineered to meet modular standards, this adaptable device accommodates displacement ranges from 80 to 1200mm. This broad range offers bridge design and construction departments the flexibility to choose the most suitable specifications, meeting the precise expansion and contraction demands of the bridge superstructure.
