GQF-C-type Bridge Expansion Devices

Specifications

Product Description
GQF-C-type Bridge Expansion Devices

    1. It is used for bridge and highway expansion joints.

    2. Good quality and competitive price.

     We produces a bridge and highway expansion joints are equipped with a rubber-type devices.

Almost every bridge and highway in China is using our products.

The scope of application of a GQF-C-type Bridge Expansion Devices:

        GQF-C-type Bridge Expansion Devices allow for large lateral, horizontal and transverse movements in bridge
structures, either through diurnal, moving load transfer or wind movement or seismic event. Typically these movements
are above +/- 600mm laterally. This is the most reliable and sophisticated road movement joint available to handle
multi dimensional movement.

Technical requirements of  GQF-C-type Bridge Expansion Devices:

        1. Neoprene rubber used (ie, CR, applied to the temperature of -25 - +60 ) or the use of natural rubber (that is, NR,
applied to the temperature of -40 - +60 region)

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

GQF-C-type Bridge Expansion Devices

         GQF-C-type bridge expansion device is adapted to the construction of roads and bridges in China a new type of bridge expansion joint devices. GQF-C-type bridge expansion device using the whole hot-rolled special steel 16Mn, overcome the special steel extrusion line and uneven collection of size characteristics, GQF-C-type bridge expansion joint integrated
technical performance and technical indicators are at or better than similar products in the advanced level and
special-shaped steel structure is an internal initiative rolling, traffic will become a recommended industry standard
products.

         GQF-C-type bridge expansion joint product features: Low building height, the overall shape of domestic hot-rolled special steel height 50mm, simple structure, easy installation, with significant reliability, comfort and durability. For Deck thickness equal to or greater than 80mm, less than or equal to 80mm telescopic amount of the various bridges, both for the convenience of the old bridge expansion joint replacement, but also for the selection of a new bridge built.

        GQF-C-type bridge expansion joint rubber seal the middle of its technical requirements: The use of chloroprene rubber (CR) rubber seal with the application of the telescopic device and a temperature of -25 - +60 region. The use of natural rubber (NR) sealed with rubber installation of expansion joints for a temperature of -40 - +60 areas. Almost every highway and bridge in China is using our products.
