Abstract

A bridge expansion joint covering structure is used for covering the pavement of a bridge expansion joint and comprises a rubber body (9) which is flush with a bridge pavement in horizontal height, a support body (8) located in the rubber body (9) as well as two extending support parts (7) which can move in the support body (8) in the same direction and in the opposite directions and are mutually symmetric in structure, wherein each of the two extending support parts (7) comprises a horizontal extending head part (721) horizontally sliding in a sliding chute (81) in the support body (8), a vertical extending part (72) connected with the horizontal extending head part (721) and a support arm (71) which is connected with the lower end of the vertical extending part (72) and extends in the direction of an adjacent bridge structure body, and support discs (73) which are used for being butted against the adjacent bridge structure body are arranged at the end parts of the two extending support parts (7).

Description

technical field [0001] The invention relates to the field of bridges, in particular to a covering structure for bridge expansion joints. Background technique [0002] The pavement of bridges is often provided with expansion joints to provide allowances for thermal expansion and contraction. For the sake of driving safety and maintaining the performance of the bridge pavement, it is often necessary to fill or cover such expansion joints with elastic objects. It is known to cover or pad with materials such as elastic rubber. However, the installation of this elastic rubber material requires further processing such as surface cutting of the base of the pavement in order to install the elastic material in place. And this is easy to cause damage to these processed parts during driving and then damage the pavement matrix. Moreover, the installation and disassembly of this elastic material also requires a lot of manpower and time costs. Contents of the invention [0003] The ...
