expansion joints, finger type expansion joints, elastomeric rubber
bridge expansion joints and asphalt expansion joints, they are used
on highways and briges to reduce the vibration and pressure from
the various of traffic tools when they pass through, in this way to
protect the highways and bridges.Product DescriptionFinger-shaped
expansion joint is a packaged type expansion device an mainly
applied to the device with the extension 20-320mm.This type of

connects with two sides of joint and the whole of finger shape
plate and moving finger shape plate that can fit together with

expansion joint: In order to meet the requirement of bridge deck
deformation, expansion joint is usually set between two beam ends,
between beam ends and abutment or at the hinge position of bridge.
Expansion joints are required to be free and reliable in both
directions parallel to and perpendicular to the axis of the bridge.
Vehicles should pass smoothly without jumping and noise. Rainwater
and garbage and soil should be prevented from seeping into the
blockage. Installation, inspection, maintenance and removal of dirt
should be simple and convenient. At the place where expansion
joints are set up, the railings and deck pavement shall be
disconnected.The function of bridge expansion joint is to adjust
the displacement and connection between the superstructure caused
by vehicle load and bridge building materials. Once the expansion
device of skew bridge is destroyed, it will seriously affect the
speed, comfort and safety of driving, and even cause traffic safety
accidents. /* January 22, 2024 19:08:37
