Wind-resistant spherical steel support
The wind-resistant spherical steel support comprises an upper support plate, a spherical crown lining plate, a middle support plate and a lower support plate, the upper support plate is arranged above the spherical crown lining plate, the middle support plate is arranged below the spherical crown lining plate, the lower support plate is arranged below the middle support plate, and the middle support plate is composed of a first middle support plate body and a second middle support plate body. An anti-pulling ring is fixedly installed on the bottom face of a limiting ring at the lower end of the upper support plate, the inner diameter of the anti-pulling ring is smaller than the hole diameter of the limiting ring of the upper support plate, protrusions are arranged on the side face of the first middle base plate, first spring steel is obliquely fixed to the upper end of the anti-pulling ring, and the upper end of the first spring steel abuts against the protrusions on the side face of the first middle base plate. A vertical elastic pre-pressing structure is designed, tight attachment between the wind-resistant support and the bridge tower is effectively guaranteed, pollution to a plane sliding pair when a gap exists between the support and a bridge is avoided, and the service life of the plane sliding pair is prolonged. The anti-pulling ring and the first spring steel are fixed to the upper support plate through the bolts to form an anti-pulling structure, and the anti-falling performance is achieved.
本发明公开了一种抗风球型钢支座，包括上支座板、球冠衬板、中间座板、下支座板，所述球冠衬板上方设有上支座板，球冠衬板下方设有中间座板，中间座板下方设有下支座板，中间座板由第一中间座板与第二中间座板组成，上支座板下端限位环底面固定安装有抗拔环，抗拔环内径小于上支座板限位环的孔径，第一中间座板侧面设有凸起，抗拔环上端倾斜固定有第一弹簧钢，第一弹簧钢上端与第一中间座板侧面所设凸起相抵触；本发明设计有垂向弹性预压结构，有效保证抗风支座与桥塔之间密贴，避免了支座与桥梁出现间隙时对平面滑动副的污染，提高其使用寿命。本发明中抗拔环与第一弹簧钢通过螺栓固定于上支座板上形成抗拔结构，具有防脱性能。
