Steel Modular Bridge Expansion Joint Type F Strip Seal Bridge Expansion Joint

Product Description

Product Description

Strip Seal Expansion Joints Accommodate Up to 80 mm Movement

    for movements of up to 80 mm are expansion joints made of a single set of structural steel, rubber sealing strips and dowel rods. According to the cross-sectional shape, they are divided into 5 types, including GQF-C, GQF-F, GQF-E, GQF-Z and GQF-RG. Being fully anchored within the depth of the road surfacing, can prevent roads from cracking caused by climatic change.

    In order to meet the requirements of the bridge deformation, are usually set at each end of the bridge, between ends of the beam and abutment or on the hinge joints of the bridge. They are applied with rubber noise weaken board which can help to increase movement and reduce noise from over-passing traffic by up to 80%.

Structure:

    are consisted of countersunk screws, edge beam, rubber strip seal and dowel rods.

All parts of the strip seal expansion joints working together can make an excellent system.

Features
