Abstract

A covering device for an expansion joint of a municipal bridge is used for covering the road surface at the expansion joint of the bridge. The covering device comprises a rubber body (9) flush with the horizontal height of the bridge road surface, a supporting body (8) located inside the rubber body (9) and two extension supporting components (7) with mutually symmetrical structures and capable of moving relative to each other or opposite to each other in the supporting body (8), wherein each of the two extension supporting components (7) comprises a horizontal extension head part (721) capable of sliding horizontally in a sliding chute (81) of the supporting body (8), a vertical extension part (72) and a supporting arm (71); the vertical extension parts (72) are connected with the corresponding horizontal extension head parts (721), and the supporting arms (71) are connected with lower ends of the corresponding vertical extension parts (72) and extend towards adjacent corresponding bridge structural components; supporting discs (73) for being butted with the adjacent corresponding bridge structural components are arranged at ends of both vertical extension parts (72).

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 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 [00...
