A bridge expansion joint covering device with improved service life

Abstract

The invention provides service life prolonged bridge expansion joint covering equipment which is used for covering the road surface at a bridge expansion joint. The bridge expansion joint covering equipment comprises a rubber body (9) flush with the horizontal height of the bridge road surface, a supporting body (8) located in the rubber body (9) and two extending and supporting parts (7) capable of moving towards each other or away from each other in the supporting body (8) and symmetric in structure, wherein each of the two extending and supporting parts (7) comprises a horizontal extension head part (721) capable of horizontally sliding in a sliding groove (81) of the supporting body (8), a vertical extension part (72) connected with the horizontal extension head part (721) and a supporting arm (71) connected with the lower end of the vertical extension part (72) and extending towards an adjacent bridge structure body; and the ends of the two extending and supporting parts (7) are each provided with a supporting plate (73) used for abutting against the adjacent bridge structure body.

Description

technical field

[0001] The invention relates to the field of bridges, in particular to bridge expansion joint covering equipment with improved service life. 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...
