Product Description
Product Description
Strip Seal Expansion Joints Accommodate Up to 80 mm Movement
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%.
Structure
Strip seal expansion joints are consisted of countersunk screws, edge beam, rubber strip seal and dowel rods.
Strip seal expansion joints 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.
Functions
*Expansion adaptation: Absorbs longitudinal, transverse and vertical displacements with compensation range 40-1200mm
*Waterproof sealing: Prevents rainwater and debris from penetrating girder gaps to protect substructure
*Shock absorption & noise reduction: Cushions vehicle impact and reduces noise by 10-15 decibels
*Load transmission: Uniformly distributes wheel loads to girders to avoid stress concentration
*Safety protection: Prevents vehicles and pedestrians from falling and maintains deck flatness
Features
*High load capacity: Compressive strength ≥30MPa to meet heavy traffic demands
*Good displacement adaptability: Shear modulus 1.0-1.2MPa with fast recovery after deformation
*Excellent durability: Ozone and UV resistant with 30-year design life
*Reliable waterproofing: No leakage under 0.2MPa water pressure for 24 hours
*Easy installation and maintenance: Modular design with standardized anchorage system
Specification
*Rubber material: chloroprene rubber (CR) or natural rubber (NR).
*Head Type: Straight or bending.
*Cross-sectional shape: GQF-C, GQF-F, GQF-E, GQF-Z and GQF-RG.
*Head Type: Straight or bending.
*Cross-sectional shape: GQF-C, GQF-F, GQF-E, GQF-Z and GQF-RG.

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.
