Bridge deck wind-resistant device for large-span pedestrian landscape suspension bridge
The invention discloses a bridge deck wind-resistant device for a large-span pedestrian landscape suspension bridge, and belongs to the technical field of bridge engineering. A plurality of adjusting plates arranged in the width direction of the hollowed-out bridge floor are arranged on the lower surface of the hollowed-out bridge floor, the middles of the two ends of each adjusting plate are rotationally connected to the side box girders, and wind power driving mechanisms used for controlling the rotating angles of the adjusting plates are arranged below the two ends of each adjusting plate; the wind power driving mechanism comprises a plurality of lifting ropes, a first slotted hollow rod, an internal sliding rod, a second slotted hollow rod, a traction rope and a sliding blade, the first slotted hollow rod is arranged in the width direction of the hollow bridge plate, the two ends of the first slotted hollow rod are fixed to the side box girder, and the internal sliding rod is arranged in the first slotted hollow rod in a sliding mode; one ends of the lifting ropes are fixed to the two edges, in the width direction, of the adjusting plates respectively. According to the technical scheme, the problem that in the prior art, the wind resistance effect of a bridge is difficult to achieve the best due to the fact that the bridge floor ventilation rate cannot be adjusted along with wind grades is solved.
本发明公开了一种用于大跨度人行景观悬索桥的桥面板抗风装置，属于桥梁工程技术领域。所述镂空桥面的下表面设有若干沿镂空桥面宽度方向设置的调节板，所述调节板的两端中部转动连接于边箱梁上，所述调节板的两端下方均设有用以控制调节板旋转角度的风力驱动机构；所述风力驱动机构包括若干吊绳，第一开槽空心杆、内部滑杆、第二开槽空心杆、牵引绳和滑动叶片，所述第一开槽空心杆沿镂空桥板的宽度方向设置，且两端固定于边箱梁上，所述内部滑杆滑动设置于第一开槽空心杆内，若干所述吊绳的一端分别固定于若干调节板宽度方向的两边缘上。本技术方案解决现有技术中的桥面透风率不能随着风力等级进行调整，导致桥梁的抗风效果难以达到最佳的问题。
