Abstract

A simple bridge expansion joint covering mechanism is used for covering the pavement positions of bridge expansion joints and comprises a rubber body (9) flush with bridge pavements in the horizontal height, a support body (8) located in the rubber body (9) as well as two extension support pieces (7) which can move in the support body (8) oppositely and adopt symmetric structures, wherein each of the two extension support pieces (7) comprises a horizontal extension head (721) capable of horizontally sliding in a sliding chute (81) of the support body (8), a vertical extension part (72) connected with the horizontal extension head (721) as well as a support arm (71) which is connected with the lower end of the vertical extension part (72) and extends towards adjacent bridge structure bodies, and support disks (73) propped against the adjacent bridge structure bodies are arranged at ends of the two extension support pieces (7).

Description

technical field [0001] The invention relates to the field of bridges, in particular to a simple bridge expansion joint covering mechanism. 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] Th...
