Product Description

Product Description

Strip seal expansion joints 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, strip seal expansion joints can prevent roads from cracking caused by climatic change.

In order to meet the requirements of the bridge deformation, strip seal expansion joints 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%.

Application

• Strip seal expansion joints are suitable for kinds of bridges which are curved, slope, skew and wide. They can also perform well on both new-built bridges and bridges have been built, both asphalt and concrete bridge surface. It also can be used in the highway.
• Having a limited depth of the structure and being able to be installed quickly, strip seal expansion joints are extremely well-positioned to replace the damaged one in a restoration project.

Feature

• Strip seal expansion joints are retractable and solid on both directions parallel and perpendicular to the bridge axis to ensure vehicles runs smoothly and no noise.
• Strip seal expansion joints can prevent rainwater permeation and dirt clogging.
• Strip seal expansion joints are simple and easy to install, check, maintain and clean.
• High strength, can withstand the weight of vehicles and pedestrians.
