Bridge wind-resistant support
The invention provides a bridge wind-resistant support which comprises an upper support plate, a middle support plate, a lower support plate and a base plate, the lower support plate is movably arranged on the base plate, the middle support plate is rotatably arranged on the lower support plate, the upper support plate is movably arranged on the middle support plate, and a plane friction pair is arranged between the upper support plate and the middle support plate. A rotating friction pair is arranged between the middle seat plate and the lower seat plate, a cylindrical spring and an annular spring are arranged between the lower seat plate and the base plate, the annular spring is used for buffering energy consumption when the lower seat plate moves in the transverse bridge direction, and the cylindrical spring is used for improving the rebound resilience when the lower seat plate moves in the transverse bridge direction. Through the arrangement of the annular spring, the effect of buffering energy consumption is achieved when the wind-resistant support bears a transverse wind load, the wind-resistant support is prevented from being greatly deformed within a short time, the use safety of the beam body is guaranteed, and through the arrangement of the cylindrical spring, the transverse wind load borne by the wind-resistant support is improved, and meanwhile the transverse wind load borne by the wind-resistant support is reduced. And the resilience force of the wind-resistant support is increased.
本发明提供一种桥梁抗风支座，包括上座板、中座板、下座板和底座板，下座板可向移动地设置在底座板上，中座板可转动地设置在下座板上，上座板可移动地设置在中座板上，在上座板与中座板之间设置有平面摩擦副，在中座板与下座板之间设置有转动摩擦副，在下座板和底座板之间设置有圆柱弹簧和环形弹簧，环形弹簧用于下座板沿横桥向移动时的缓冲耗能，圆柱弹簧用于提升下座板沿横桥向移动时的回弹性能。本发明通过环形弹簧的设置，在抗风支座受到横向风载时起到缓冲耗能的作用，避免抗风支座在短时间内发生大幅度变形，保证了梁体的使用安全性，再通过圆柱弹簧的设置，在提高抗风支座所能承受横向风载的同时，增大了所述抗风支座的回弹力。
