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 component for covering bridge expansion joints. Background technique [0002] The pavement of the bridge is often provided with expansion joints to provide a margin for thermal expansion and contraction. In order to drive safety and maintain the performance of the bridge pavement, it is often necessary to fill or cover such expansion joints with elastic objects. The known method is to use materials such as elastic rubber to cover or stuff. However, the installation of this kind of elastic rubber material requires reprocessing such as surface cutting to the matrix of the road surface in order to install the elastic material in place. This is easy to cause damage to these processed parts during driving and damage the pavement matrix. Moreover, the installation and disassembly of this elastic material also requires a lot of manpower and time costs. Summary of the invention [0003] T...
