single strip railway bridge expansion joint

Detailed Product Description 1.Expansion Joint for Bridge 2.Certificate:ISO9001:2000 3.Sizes:up to the customers

  Single Strip seal elastromeric joint product features:

Building height is low, the whole domestic hot forming profiled bar height only fifty mm, simple structure, easy installation, has the obvious reliability, comfort and durability. Suitable for bridge deck pavement layer thickness is equal to or greater than 80 mm, expansion amount less than or equal to 80 mm all kinds of Bridges, which is convenient for the old bridge expansion joint replacement, and to build a new bridge choose. Because some expansion joint installation discomfort can produce jump car phenomenon, not only in the domestic highway Bridges are in foreign countries, and has not yet solved, therefore, we in order to eliminate the steps, prevent jump out of the vehicle, maintain good road conditions, the relevant departments and the construction unit adopted many effective measures and method, moving up largely reduce the bridge expansion joint diseases jump out of the vehicle. The installation of bridge expansion joint construction of the highway bridge construction is an important construction projects, installation quality has a direct influence on the stability and comfort of driving a large bridge, the quality of service and service life.

  Single Strip seal elastromeric joint technical requirements:

Using chloroprene rubber (CR) seal rubber belt of the expansion joint and temperature is 25 °C for - - + 60 °C area. Using natural rubber (NR) seal rubber belt of the expansion joint device suitable for temperature for - 40°C to + 60 °C area.

Highway bridge expansion joint is a setting in the bridge superstructure activities end, floor off joint telescopic device. Install expansion device is used to ensure that the upper structure in the temperature variation and concrete shrinkage and creep, and loads, in its deflection can realize, and do not produce additional additional internal forces, and can ensure running smoothly. Usually the domestic bridge expansion joint are set in the upper structure of the activity end and bridge abutment, and each group (hole) in the upper structure cohesion. General highway bridge in the roadway and the sidewalk along the bridge transverse direction through long Settings, rail in juncture place should also interrupt to ensure that the structure of the free deflection, avoid tensile splitting; In the joint of the bridge deck waterproof layer is still should be properly laid, prevent rain bearing structure. If use open type of bridge expansion joint, also should consider to remove dirt, and in the joint installed below the cutoff and pilot plant, the water discharge bridge. Domestic medium and large railway bridge similarly also needs to set expansion joint, in ballast floor, should consider to prevent ballast fall joint of the measures.
