Structural Features
High-strength bolts are used, typically with internal or external hexagonal heads.
Anti-slip washers or toothed washers are often provided under the bolt heads to improve loosening resistance.
Some models include locating pins or limiting structures for quick alignment with the bridge deck mounting holes.
The surface is generally treated with hot-dip galvanizing or Dacromet coating to improve corrosion resistance.
Product Function
- Longitudinal Connection Between Panels: Connects parallel bridge deck panels at longitudinal joints, preventing misalignment or separation between panels and ensuring the continuity and integrity of the bridge deck.
- Transferring Shear Force and Loads: When vehicle wheels press down on a single panel, the load can be partially transferred to adjacent panels through the shear connections formed by these bolts, achieving lateral load distribution and enabling multiple panels to work together, thus improving the bridge deck's load-bearing capacity.
- Fixing to Crossbeams: Some bolts are also used to anchor the edges or specific locations of the bridge deck to the underlying crossbeams, preventing the entire bridge deck from shifting or lifting.
Application Areas
Military and Emergency Support Engineering; Infrastructure Construction and Building; Heavy-Duty Transportation and Specialized Industries; Semi-Permanent and Permanent Bridge Construction
