Tips: Requirements expansion device of rubber waterstop bridge expansion joint of bridge technology GQF-C:...

Requirements expansion device of rubber waterstop bridge expansion joint of bridge technology GQF-C:

1 the use of rubber (CR, -25, suitable for temperature in -+60 c) or the use of natural rubber (i.e. NR, suitable for temperature at -40 C -+60 C)

2 steel plate used in the expansion device, quality requirements in line with the provisions of GB374, GB012, the use of profiled steel, (that is, 16MN or Q345) in line with the provisions of JT/T1591.

Overview of expansion device of rubber waterstop bridge expansion joint of GQF-C bridge is to adapt to a new type of bridge expansion joint of highway bridge construction in our country. The GQF-C device type bridge expansion device adopts whole hot rolled 16Mn shaped steel, overcome the extrusion special-shaped steel straightness and set size uneven, GQF-C type bridge expansion device comprehensive technical performance and the technical indicators have reached or exceeded the international advanced level of similar products, structure and special-shaped steel rolling are the first domestic transportation industry will become the standard recommended products.

The middle type GQF-C bridge expansion device of rubber sealing strip the technical requirements: the use of chloroprene rubber (CR) sealing expansion device and temperatures for rubber belts for -25 -+60 DEG C area. The use of natural rubber (NR) sealing telescopic rubber belt joint device applicable to the temperature of -40 DEG -+60 DEG area.
