Expansion joints (beam end waterproofing devices) are important ancillary facilities at the beam end, and their quality directly affects the durability of the bridge. This expansion joint is a combination of aluminum alloy profiles and rubber bands, suitable for box girder structures, easy to install, and can be quickly replaced.
The expansion joint design has an expansion capacity between 30-200mm. The stretching amount is divided into seven levels: 30mm (± 15mm), 60mm (± 30mm), 80mm (± 40mm), 100mm (± 50mm), 120mm (± 60mm), 160mm (± 80mm), 200mm (± 100mm).
