Abstract

The invention provides a bridge expansion joint covering device capable of increasing the service performance of a bridge, which is used for covering pavements of bridge expansion joints. The bridge expansion joint covering device comprises a rubber body (9) flush with a bridge pavement in horizontal height, a support body (8) positioned in the rubber body (9) and two extension support members (7) which can move in the same direction or the opposite directions in the support body (8) and are mutually symmetrical in structure, wherein each of the two extension support members (7) comprises a horizontal extension head (721) capable of horizontally sliding in a sliding chute (81) of the support body (8), a vertical extension part (72) connected with the horizontal extension head (721), and a support arm (71) connected with the lower end of the vertical extension part (72) and extending to an adjacent bridge structure body, wherein the end part of each of the two extension support members (7) is provided with a support disk (73) for being butted with the adjacent bridge structure body.

Description

technical field [0001] The invention relates to the field of bridges, in particular to bridge expansion joint covering equipment for improving the service performance of bridges. 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. ...
