Streamline steel box girder with section wind-induced vibration suppression structure
The invention discloses a streamline steel box girder with a section wind-induced vibration suppression structure, and relates to the technical field of streamline steel box girders, the streamline steel box girder comprises a streamline steel box girder main body, a plurality of handrails are arranged on the two sides of the streamline steel box girder main body at intervals, and the lower ends of the handrails are fixed on the streamline steel box girder main body; the upper ends of the upper inclined webs located on the two sides of the streamline steel box girder body are each provided with a water collecting groove, the length of the water collecting grooves is equal to that of the streamline steel box girder body, each water collecting groove comprises a water collecting inclined plate, a water collecting vertical plate and a water collecting transverse plate, the water collecting inclined plates are installed on the upper inclined webs in parallel, and one end of each water collecting transverse plate is fixed to the upper end of the corresponding water collecting inclined plate. A plurality of drainage pipes are fixed to the face, away from the water collection inclined plate, of the water collection vertical plate at intervals. A base does not need to be arranged at the lower end of the handrail, the air streaming characteristic of the streamline steel box girder body is changed, and vortex-induced vibration is reduced.
本发明公开了一种具有断面风致振动抑制结构的流线型钢箱梁，涉及流线型钢箱梁技术领域，包括流线型钢箱梁主体，流线型钢箱梁主体的两侧间隔设有多个栏杆，栏杆的下端固定于流线型钢箱梁主体上，位于流线型钢箱梁主体两侧的上斜腹板的上端均设有一个集水槽，集水槽的长度与流线型钢箱梁主体的长度相等，集水槽包括集水斜板、集水竖板和集水横板，集水斜板平行安装于上斜腹板上，集水横板的一端固定于集水斜板的上端，集水竖板的下端固定于集水斜板的下端，集水竖板远离集水斜板的一面上间隔固定有多个排水管。本发明中的栏杆下端无需设置基座，改变流线型钢箱梁主体的空气绕流特性，降低了涡激振动的发生。
