Bridge expansion joint modulus support
When the bridge telescopic deformation of more than 50mm, often using a steel telescopic device. Steel supported bridge expansion joints when the vehicle passing due to beam end rotation or deflection and rattling effect, bridge expansion joint noise, and easy to make structural damage. Therefore, the device is provided with the spring bolt the fixed sliding plate, to reduce rattling and noise, relatively complex structure of the expansion joints.
The device is a shear type rubber belt as a filling material expansion device using a variety of different shapes. The rubber elastic, easy to paste, and can meet the requirement of deformation and waterproof. In China, has been widely used in bridge engineering.
