Problems solved by technology

During installation, the end of the rubber sealing tape is stuck in the bayonet of the steel profile. Different rubber sealing tapes are installed in different steel bayonets, so that the installation of the rubber sealing tape is subject to certain restrictions, and the installation is time-consuming and laborious. The rubber sealing tape is not easy to replace after it is damaged.

Abstract

The invention belongs to the technical field of expansion devices and discloses a damping and buffering expansion joint which is mainly and technically characterized by comprising profile steel side beams arranged pairwise, wherein a rubber sealing tape is arranged between the profile steel side beams; the top edge at the inner side of the profile steel side beam is of a concave-convex shape formed by circularly arranging convex teeth and grooves; the rubber sealing tape is fixed together with the profile steel side beam through a bolt; the bolt is arranged at the groove arranged at the inner side of the profile steel side beam; and an elastic pressing bar is arranged on the rubber sealing tape. The damping and buffering expansion joint provided by the invention has the advantages that profile steel machining is simplified, the rubber sealing tape is not needed to be limited inside a profile steel die, and therefore, simple production is realized. The length of each convex tooth is increased, so that the expansion amount of an expansion device is increased, bridge impact caused by jumping is reduced, the service life of the expansion joint and the service life of the bridge are prolonged, noise pollution to the environment is reduced, and the rubber sealing tape is convenient to replace.

Description

technical field [0001] The invention belongs to the technical field of expansion devices, in particular to a shock-absorbing buffer expansion joint and a construction method thereof. Background technique [0002] The bridge telescopic device includes steel side beams arranged in pairs, and rubber sealing belts are arranged between the steel side beams. In order to reduce noise, the top edge of the inside of the steel side beams is concave-convex with convex teeth and grooves. During installation, the end of the rubber sealing tape is stuck in the bayonet of the profiled steel, and different rubber sealing tapes are installed in different profiled steel bayonets, so that the installation of the rubber sealing tape is limited to a certain extent, and the installation is time-consuming and laborious. The rubber sealing tape is not easy to replace after it is damaged . Contents of the invention [0003] The first technical problem to be solved by the present invention is to p...
