The invention discloses a bridge expansion joint structure. The bridge expansion joint structure includes bridge bodies, asphalt layers, rubber layers and supporting layers; expansion joints are formed between the two adjacent bridge bodies; the asphalt layers are paved on the upper surfaces of the bridge bodies, and the rubber layers are fixedly connected between the two bridge bodies and cover the expansion joints; the supporting layers comprise left finger joint plates and right finger joint plates, wherein the left finger joint plates and the right finger joint plates are fixed to the twobridge bodies correspondingly; and the rubber layers are supported by the left finger joint plates and the right finger joint plates. According to the bridge expansion joint structure, the bumping phenomenon in the process of driving due to upwarping or sinking of asphalt at the expansion joints of a bridge can be relieved.
Description
technical field [0001] The invention relates to the field of bridge construction, in particular to a bridge expansion joint structure. Background technique [0002] With the rapid development of urban construction, the development of various transportation facilities is advancing by leaps and bounds. All kinds of bridges such as highways and urban viaducts have been built one after another. Due to the continuous increase of vehicle flow, vehicle speed, vehicle load and some minor problems left in the bridge construction, the damage of bridge expansion joint joints is very common. The damage of the bridge expansion joint joints will cause the vehicle to bump continuously when driving, the noise will disturb the people, and the phenomenon of jumping will increase. It will also endanger the safety of the bridge and the service life of the bridge, and increase the maintenance cost of the bridge. Therefore, the durability of the bridge, the stability of driving, and the comfort...
