Product Description
Multi-specification Bridge Comb-tooth Expansion Joint
It refers to that in order to meet the requirements of bridge floor deformation, expansion joints are usually set between the two beam ends, between the beam end and the abutment, or at the hinged position of the bridge. The function of the bridge expansion joint is to adjust the displacement and connection between the superstructure caused by the vehicle load and the bridge construction material. Once the expansion device of skew bridge is damaged, it will seriously affect the speed, comfort and safety of driving, and even cause driving safety accidents.
Parameters
Features
1. Tightness: under normal circumstances, the bridge expansion joint needs to maintain good tightness to avoid water and road debris entering the expansion joint, affecting the service life of the gap expansion and expansion module.
2. Bear load: The bridge expansion joint needs to bear the load of the bridge, and ensure that good expansion and deformation can be achieved while bearing the load.
3. Taking into account safety: the selection, manufacturing, installation and maintenance of bridge expansion joints need to take into account safety factors to ensure the normal operation and driving safety of the bridge.
