Pneumatic device for improving vortex vibration performance of split box girder
The invention discloses a pneumatic device for improving vortex vibration performance of split box girders, which belongs to the technical field of bridge construction and comprises two symmetrically arranged box girders, force guiding devices are mounted on two sides of the box girders, cross beams are equidistantly arranged between the box girders along the bridge direction, first pneumatic measures are arranged on two sides of the box girders, and second pneumatic measures are arranged on two sides of the box girders. The first pneumatic measure is composed of a vertical apron board and a horizontal spoiler, one end of the horizontal spoiler is connected with the box girder, one end of the horizontal spoiler is connected with the vertical apron board, the cross beam is connected with a base, the base is connected with a second pneumatic measure, the second pneumatic measure is composed of a cross-shaped stabilizing plate, and the cross-shaped stabilizing plate is connected with the base. And the second pneumatic measure is vertically arranged at the lower end of the base. The problems that in an existing device, a solid bridge cannot reduce the vortex vibration amplitude, and due to the fact that the solid bridge is of a double-amplitude bridge structure, when wind blows one side, the single-side stress influence is large, and the bridge connecting position is prone to being greatly damaged are solved.
本发明公开了一种改善分体箱梁涡振性能的气动装置，属于桥梁施工技术领域，包括两个对称设置的箱梁，所述箱梁两侧安装有导力装置，所述箱梁之间沿顺桥向等距设有横梁，所述箱梁两侧设有第一气动措施，所述第一气动措施包括：竖向裙板和水平扰流板组成，所述水平扰流板一端与箱梁连接，所述水平扰流板一端与竖向裙板连接，所述横梁连接有底座，所述底座连接有第二气动措施，所述第二气动措施由呈十字型稳定板组成，所述第二气动措施垂直设置在底座下端。以解决现有装置中实桥不能降低涡振振幅和因是双幅桥结构，故风吹一侧时单侧受力影响大，容易对桥梁连接处造成较大的损坏的问题。
