Abstract

The invention discloses a covering mechanism for a bridge expansion joint. The covering mechanism is used for covering a road surface with the bridge expansion joint, and comprises a rubber body (9), a support body and two extended support parts (7), wherein the rubber body (9) is parallel to the horizontal height of the bridge road surface; the support body (8) is positioned inside the rubber body (9); the two extended support parts (7) can move in one direction or opposite directions in the support body (8) and are of symmetric structures; each one of the two extended support parts (7) comprises a horizontal extended head (721) which slides horizontally in a sliding groove (81) of the support body (8), a vertical extended part (72) which is connected with the horizontal extended head (721), and a support arm (71) which is connected with the lower end of the vertical extended part (72) and extends towards an adjacent bridge structure body; support discs (73) which are propped against the adjacent bridge structure body are arranged at end parts of the two extended support parts (7).

Description

technical field [0001] The invention relates to the field of bridges, in particular to a covering mechanism for expansion joints of 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 [0003] ...
