A wind-resistant steel support

Abstract

The present invention discloses a wind-resistant ball-shaped steel support, comprising an upper support plate, a spherical crown lining plate, an intermediate plate, and a lower support plate. The upper support plate is provided above the spherical crown lining plate, the intermediate plate is provided below the spherical crown lining plate, and the lower support plate is provided below the intermediate plate. The intermediate plate is composed of a first intermediate plate and a second intermediate plate. An anti-pullout ring is fixedly installed on the bottom surface of the limiting ring at the lower end of the upper support plate. The inner diameter of the anti-pullout ring is smaller than the aperture of the limiting ring of the upper support plate. A protrusion is provided on the side of the first intermediate plate. A first spring steel is fixed at an angle on the upper end of the anti-pullout ring. The upper end of the first spring steel conflicts with the protrusion provided on the side of the first intermediate plate. The present invention is designed with a vertical elastic pre-stressing structure to effectively ensure the close fit between the wind-resistant support and the bridge tower, avoid contamination of the plane sliding pair when a gap appears between the support and the bridge, and improve its service life. In the present invention, the anti-pullout ring and the first spring steel are fixed to the upper support plate by bolts to form an anti-pullout structure with anti-slip performance.
