Butt joint type bridge expansion joint device
Docking type expansion joint device, according to its structural style and stress characteristics of different, can be divided into filling butt type and embedded type packing. Two kinds of butt butt type expansion device is to asphalt, wood, rubber and other materials caulk oakum, are under pressure, flexible body state in any case. This kind of telescopic device commonly used in conventional bridge engineering scale below 40mm, but has not seen. Embedded devices use different forms of butt joints of steel rubber strip with different shapes (with) embedded firmly, and the rubber strip (belt) tension and compression deformation to absorb the deformation of the girder the telescopic body can, in a compressed state. You can also place.
