[GQF-C40 bridge expansion joint 】Basic description
GQF-C bridge expansion joint device is a new type of bridge expansion joint device suitable for highway bridge construction in China GQF-C type bridge expansion joint device adopts integrally hot-rolled 16Mn profiled steel, which overcomes the characteristics of uneven straightness and aggregate size of extruded profiled steel. The comprehensive technical performance and technical indicators of GQF-C type bridge expansion joint device reach or exceed the advanced level of all similar products. The structural type and profiled steel rolling belong to domestic * * *, and will become the standard recommended product in the transportation industry
The product features of GQF-C bridge expansion joint device: the building height is low, and the height of domestic hot-rolled integral shaped profiled steel is only 50 mm. It is simple in structure, easy to install, and has obvious reliability, comfort and durability. It is suitable for various bridges with a deck pavement thickness of 80 mm or more and an expansion of 80 mm or less. It is not only convenient to replace the expansion device of old bridges, but also available for new bridge construction
GQF-C type bridge expansion joint device middle rubber Sealing strip Technical requirements: Neoprene The expansion device of (CR) sealing rubber belt is applicable to areas with temperatures ranging from - 25 ℃ to 60 ℃ Natural rubber (NR) Expansion joint device with sealed rubber belt is applicable to areas with temperatures ranging from - 40 ℃ to 60 ℃. GQF-C bridge expansion joint device produced by our company is widely used in various projects!
Applicable scope of rubber used for bridge expansion joints:
1. The expansion joint device using neoprene (CR) is applicable to areas with temperature of - 25-60.
2. The expansion joint device made of natural rubber (NR) is suitable for areas with temperatures ranging from - 40 to 60.
[GQF-C40 Bridge Expansion Joint] Product Features
