Abstract

The invention discloses an expansion joint covering device for a municipal bridge, which is used for covering a road surface of a bridge expansion joint. The expansion joint covering device for the municipal bridge comprises a rubber body (9) which is flush with the horizontal level of a bridge road surface, a supporting body (8) which is positioned in the rubber body (9), and two extending supporting pieces (7) which can move in directions facing each other and opposite to each other in the supporting body (8) and are mutually symmetrical in structures, wherein each of the two extending supporting pieces (7) comprises a horizontal extending head part (721) which can horizontally slide in a sliding chute (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 used for being connected with the adjacent bridge structure body in a propping manner 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 an expansion joint covering device for municipal bridges. Background technique [0002] The pavement of bridges is often provided with expansion joints to provide a margin for thermal expansion and contraction. In order to drive safety and maintain the service performance of the bridge pavement, it is often necessary to fill or cover such expansion joints with elastic objects. A known way is to use elastic rubber or other materials for covering or packing. However, the installation of this elastic rubber material requires reprocessing such as surface cutting of the substrate of the road surface in order to install the elastic material in place. This is likely to cause damage to these processed parts during driving, thereby damaging the pavement substrate. Moreover, the installation and removal of this elastic material also requires a lot of labor and time costs. SUMMARY OF THE INVENTI...
