Abstract

The invention relates to a covering device for an expansion joint of a bridge pavement. The covering device for the expansion joint of the bridge pavement is used for covering a pavement part of the bridge expansion joint, and comprises a rubber body (9) flush with the horizontal height of the bridge pavement, a support body (8) located inside the rubber body (9), and two extending support pieces (7) capable of moving face to face and reversely in the support body (8) and having mutually symmetrical structures, wherein each of the extending support pieces (7) comprises a horizontal extending head part (721) capable of horizontally sliding in a sliding chute (81) of the support body (8), a vertical extending part (72) connected with the horizontal extending head part (721), and a support arm (71) connected with the lower end of the vertical extending part (72) and extending toward an adjacent bridge structure body; support plates (73) abutted with the adjacent bridge structure body are respectively arranged on end parts of the two extending support pieces (7).

Description

technical field [0001] The invention relates to the field of bridges, in particular to an expansion joint covering device for bridge road surfaces. 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 ...
