Double-layer truss bridge shielding type guardrail
The invention discloses a double-layer truss bridge shielding type guardrail, and belongs to the technical field of bridge guardrails. Comprising a shielding type guardrail unit of a plurality of assemblies, the shielding type guardrail unit comprises a guardrail skirting, a first handrail cross rod, a second handrail cross rod, a plurality of stand columns, a plurality of vertical pipes, a plurality of barrier strips, a sliding plate and a plurality of rack assemblies, the guardrail skirting is arranged on the lower portion of the shielding type guardrail unit in the length direction, and the lower portion of the guardrail skirting is connected with a bridge floor; the first handrail cross rod and the second handrail cross rod are arranged above the shielding type guardrail unit in the length direction, a certain distance exists between the first handrail cross rod and the second handrail cross rod, the stand columns are arranged at the two ends of the shielding type guardrail, and the stand columns are connected with the guardrail skirting, the bridge floor, the first handrail cross rod and the second handrail cross rod. The vertical pipes are arranged between the two stand columns at equal intervals, the upper ends of the vertical pipes are connected with the second handrail cross rod, the lower ends of the vertical pipes are connected with the guardrail skirting, sliding devices are arranged in the vertical pipes, and the sliding devices are arranged on the inner walls of the shielding type guardrail stand columns. According to the shielding type guardrail in the technical scheme, the form of the shielding type guardrail can be changed according to different vibration amplitudes of the cross section of a bridge, the safety performance of the bridge is guaranteed, and fatigue damage of bridge components caused by vortex-induced vibration is avoided.
本发明公开了一种双层桁架桥梁遮挡式护栏，属于桥梁护栏技术领域。包括若干组件的遮挡式护栏单元，所述遮挡式护栏单元包括护栏踢脚、第一扶手横杆、第二扶手横杆、若干立柱、若干竖管、若干障条、滑板、若干齿条组件，所述护栏踢脚设置于遮挡式护栏单元长度方向的下方，且护栏踢脚的下方与桥面连接，所述第一扶手横杆和第二扶手横杆设置于遮挡式护栏单元长度方向的上方，第一扶手横杆与第二扶手横杆存在一定距离，所述立柱设置于遮挡式护栏两端，且立柱与护栏踢脚、桥面、第一扶手横杆和第二扶手横杆连接，所述竖管等间距布置于两立柱之间，竖管上端与第二扶手横杆连接，竖管下端与护栏踢脚连接，竖管内设置滑动装置，所述滑动装置设置于遮挡式护栏立柱的内壁上。本技术方案中的遮挡式护栏能够根据桥梁断面不同振动幅值，改变遮挡护栏的形式，保证桥梁的安全性能，避免桥梁构件因涡激振动产生疲劳破坏。
