Abstract

The invention discloses a bridge expansion joint coverage device capable of stably running. The device is used for covering a road surface of a bridge expansion joint. The device comprises a rubber body (9) flush with the horizontal height of a bridge road surface, a supporting body (8) positioned in the rubber body (9), and two extended supporting parts (7) capable of moving forwards and backwards in the supporting body (8) and symmetric to each other in structure, wherein each of the two extended supporting parts (7) comprises a horizontal extended head part (721) capable of horizontally sliding in a sliding groove (81) of the supporting body (8), a vertical extended part (72) connected with the horizontal extended part (721), and a supporting arm (71) connected with the lower end of the vertical extended part (72) and extending towards adjacent bridge structure bodies; and a supporting plate (73) abutted with the adjacent bridge structure bodies is arranged at each of the end parts of the two extended supporting parts (7).

Description

technical field [0001] The invention relates to the field of bridges, in particular to a bridge expansion joint covering device capable of stable operation. 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 inve...
