Setting of bridge expansion joint

The bridge expansion joint is to meet the requirement of bridge deformation, usually between two beam end hinged position between the girder and the abutment or bridge set expansion joints. The expansion joints in parallel, two direction perpendicular to the axis of the bridge, can free expansion, firm and reliable, the vehicle should be smooth running out no, jump and noise; to prevent rainwater and waste soil infiltration obstruction; installation, inspection, maintenance, remove the dirt will be simple and convenient. In the setting of expansion joints, rail and bridge deck pavement are disconnected.

According to the joint performance and installation methods can be divided into: GQF-C type, GQF-Z type, GQF-D type, GQF-F type, GQF-MZL type and GQF-MZL type mode! The number of bridge expansion joint device, is the overall design of special-shaped steel bridge expansion joint device of hot rolling forming. The GQF-C type, GQF-Z type, GQF-D type, GQF-F type expansion joint bridge joint device is suitable for the expansion of the 80mm below the GQF-MZL type, GQF-160 type, GQF-240 type, GQF-320 type expansion joint device is composed of the side beam, inBeam, modular bridge expansion joints composed of crossbeam and linkage device, suitable for large and medium span bridge expansion of 80mm-1200mm.
