Detailed Description
The invention will be further elucidated and described with reference to a specific embodiment. The utility model discloses in the technical characteristics of each embodiment under the prerequisite that does not conflict each other, all can carry out corresponding combination.
As shown in fig. 1-3, the maintenance-free rubber sealing strip of the bridge expansion device of the utility model is arranged in the expansion joint; the top surface of the sealing strip is a wave-shaped top surface 2, the two sides of the bottom surface of the sealing strip are provided with outwards convex buckle strip structures 3, the section of the bottom surface of the sealing strip is an oval cambered surface 4, and a middle hollow structure 5 is arranged in the sealing strip. The cross section shapes of the sealing belt are consistent along the length direction, namely the buckle strip structure 3 and the middle hollow structure 5 are arranged along the length direction of the sealing belt. The oval shape of lower bottom can laminate with existing bird type rubber sealing strip, and when the telescoping device stretched out and drawn back, when both sealing strip stretched and compressed, the smooth cambered surface of lower surface was maintained.
In this embodiment, the upper surface flushes with the bridge floor, both can avoid debris such as silt to block up the expansion joint, again can be when the telescoping device is flexible, when both non-maintaining rubber sealing tape is tensile to be compressed, maintain the upper surface and flush with the bridge floor, the noise that produces when can also reducing the vehicle and pass through.
