Abstract

The invention discloses a high-stability bridge expansion joint covering assembly, which is used for covering pavements at bridge expansion joints, and comprises a rubber body (9) flush with a horizontal level of a bridge pavement, a support body (8) located in the rubber body (9), and two extension supporting members (7) which can move in the support body (8) in the directions facing each other and opposite to each other and are symmetrical to each other in structure, wherein each of the two extension supporting members (7) comprises a horizontal extending head (721) capable of horizontally sliding in a chute (81) of the support body (8), a vertical extending part (72) connected with the horizontal extending head (721), and a supporting arm (71) which is connected to the lower end of the vertical extending part (72) and extends toward an adjacent bridge structure; supporting disks (73) being propped against the adjacent bridge structure are arranged at the end parts of the two extension supporting members (7).

Description

technical field [0001] The invention relates to the field of bridges, in particular to a bridge expansion joint covering component with high stability. 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...
