Bridge expansion joint device and bridge assembly thereof
The bridge expansion joint device comprises a bearing support, a fixed rib, a movable rib and a pre-tightening device, and the fixed rib and the bearing support are used for being erected on the two sides of a bridge expansion joint in the longitudinal bridge direction; in the longitudinal bridge direction, one end of the movable rib is used for being connected with the bearing support, the other end of the movable rib extends towards one side of the fixed rib and is movably connected with the fixed rib, a mounting space is formed between the movable rib and the fixed rib, and the movable rib comprises a vertical rib plate extending towards the bottom of the mounting space; the pre-tightening device is arranged in the installation space and abuts against the position between the vertical rib plate and the fixing rib so as to apply transverse pressure to the vertical rib plate. The pre-tightening device is connected between the movable rib and the fixed rib in an abutting mode, the pre-tightening device applies transverse pressure to the movable rib, vertical sliding friction resistance is provided for the movable rib, vertical vibration of the movable rib when a vehicle passes through the device is restrained, the vibration characteristic of the device can be improved, noise is reduced, and the service life of the device is prolonged. And structural fatigue damage caused by vibration is reduced.
本申请涉及一种桥梁伸缩缝装置及其桥梁总成，其包括：承载支座、固定肋、活动肋和预紧装置，固定肋和承载支座用于沿纵桥向架设于桥梁伸缩缝两侧；沿纵桥向，活动肋一端用于与承载支座连接，另一端向固定肋一侧延伸，并与固定肋活动连接，活动肋与固定肋之间形成一安装空间，活动肋包括向安装空间底部延伸的竖向肋板；预紧装置设置于安装空间内，预紧装置抵持于竖向肋板与固定肋之间，以向竖向肋板施加横向压力。本发明中，在活动肋与固定肋之间抵接预紧装置，预紧装置向活动肋施加横向压力，对活动肋提供了一个竖向的滑动摩擦阻力，抑制车辆经过该装置时活动肋的竖向振动，可提升该装置的振动特性，降低了噪声，减少了振动引起的结构疲劳破坏。
