The invention relates to a damping bracket. The damping bracket is mounted on a structural column provided with a crane through a U-shaped hoop, a pressing plate and a nut. The vertical load on the bracket bearing plate is borne through the friction force between the U-shaped hoop assembly and the structural column and the friction force between the steel structure bracket and the structural column and the shear force possibly borne by the safety stack. The shock absorption sleeve is arranged on the stress face, in direct contact with the structural column, of the U-shaped hoop, the side plate vibration isolation pad is arranged on the close attaching face of the steel structure bracket and the structural column, and the structural noise of crane operation is cut off through the vibration isolation pad and the shock absorption sleeve, so that the influence of the crane operation noise on the human settlement environment of the rail transit field section upper cover residence is reduced. A safety stack protruding out of the structural column face is arranged on the structural column, and a safety bearing steel plate is arranged on the safety stack. The safety bearing plate is attached to an anti-loosening bottom plate of the steel structure bracket, and a bottom plate vibration isolation pad is arranged between the two attaching faces. The bottom plate vibration isolation pad is used for preventing the steel structure bracket from falling due to looseness of a U-shaped hoop nut, and meanwhile the bottom plate vibration isolation pad plays a role in noise elimination and shock absorption.
本发明涉及减震型牛腿，其通过U型抱箍、压板及螺母安装于设有起重机的结构柱上。通过U型抱箍组件和钢结构牛腿与结构柱的摩擦力及安全垛可能承受的剪力承受牛腿承托板上的竖向载荷。U型抱箍与结构柱直接接触的受力面设置有减震套，钢结构牛腿与结构柱密贴面设置有侧板隔振垫，通过隔振垫和减震套切断起重机运行的结构噪声，从而减少了起重机运行噪音对轨道交通场段上盖住宅人居环境的影响。结构柱上设置了突出于结构柱面的安全垛，安全垛上设置了安全承托钢板。安全承托板与钢结构牛腿的防松底板贴合，两帖合面之间设置有底板隔振垫。用于防止U型抱箍螺母松动导致的钢结构牛腿下坠，同时底板隔振垫起到消声减震作用。
