Bridge expansion joint device

Abstract

The invention discloses a bridge expansion joint device, including an expansion joint disposed between adjacent two bridge bodies, wherein the each bridge body comprises a concrete matrix and a firststeel body and a second steel body coated on both ends of the concrete matrix, the second steel body is provided with an expansion groove near the upper end surface of the expansion joint, a cover plate slidably matched with the expansion groove is fixedly installed on the end face of the first steel body close to the expansion joint, the cover plate is provided with a groove whose opening faces upward and extends left and right, the bottom wall of the groove is provided with a through groove which is communicated with each other vertically and extends left and right, the expansion joint is provided with a collecting plate which extends forward and backward and is inclined, The collecting plate comprises an arc-shaped part and a fixing part located on the left and right sides of the arc-shaped part. A first sliding groove with an opening facing the expansion joint and extending forward and backward is inclined in the first steel body, and a plurality of second sliding grooves with theopenings facing upward and spaced forward and backward are arranged above the first sliding groove.

Description

technical field [0001] The invention relates to the field of bridges, in particular to a bridge expansion joint device. Background technique [0002] Expansion device is an important component of the bridge. It is a general term for various devices composed of rubber and steel components installed at the expansion joints of the bridge in order to allow vehicles to pass through the bridge deck smoothly and meet the needs of the deformation of the upper structure of the bridge. Expansion joints are gaps set in the bridge superstructure to meet the needs of material expansion and contraction deformation. [0003] Dust and sundries are often accumulated in the expansion joints, so after the rainwater falls, the rainwater cannot be discharged in time, and the rainwater will erode the bridge body, which will reduce the service life of the bridge body and cause poor shockproof effect , and the traditional expansion joints often rely on cleaning personnel to deal with them when cle...

Problems solved by technology

[0003] Dust and sundries are often accumulated in the expansion joints, so after the rainwater falls, the rainwater cannot be discharged in time, and the rainwater will erode the bridge body, which will reduce the service life of the bridge body and cause poor shockproof effect , and the traditional expansion joints often rely on cleaning personnel to deal with them when cleaning them. On the viaduct with a large traffic flow, cleaning is very inconvenient and there is a great potential safety hazard, and the cleaning often affects traffic and causes traffic. jam
