Abstract

The invention discloses a cover component for covering a bridge expansion joint, which is used for covering a road surface of the bridge expansion joint. The cover component comprises a rubber body (9) which is flush with the level of the road surface of a bridge, a supporting body (8) which is positioned in the rubber body (9), and two extending supporting pieces (7) which can move face to face or in the opposite directions in the supporting body (8) and are structurally symmetrical with each other, wherein each of the two extending supporting pieces (7) comprises a horizontal extending head part (721) which can slide horizontally in a sliding groove (81) of the supporting body (8), a vertical extending part (72) which is connected with the horizontal extending head part (721) and a supporting arm (71) which is connected with the lower end of the vertical extending part (72) and extends towards an adjacent bridge structure body, wherein a supporting disc (73) which is pressed against the adjacent bridge structure body is arranged at the end part of each of the two extending supporting pieces (7).

Description

technical field [0001] The invention relates to the field of bridges, in particular to a covering assembly for covering expansion joints 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. Contents of the invention ...
