Bridge damping support

Abstract

The invention relates to a bridge damping support. The bridge damping support comprises an elastic rubber column and a connecting mechanism, the connecting mechanism comprises two nylon sleeves and atleast three hoops, each nylon sleeve comprises a thick neck sleeve and a thin neck sleeve, the thick neck sleeve sleeving the outer circumference of a boss on the bottom face of a bridge is fixed tothe boss on the bottom face of the bridge through the corresponding hoop, the thick neck sleeve sleeving the outer circumference of a pier is fixed to the pier through the corresponding hoop, the freeends of the two thin neck sleeves sleeving the elastic rubber column are arranged in the middle of the elastic rubber column in an overlapped mode to form a double-layer structure, the double-layer structure is fixed to the elastic rubber column through the corresponding hoop, and the nylon sleeves are in the tight state by the hoops. Due to existing of the nylon sleeves, the strength of the elastic rubber column is improved by the thin neck sleeves, the condition that the elastic rubber column is pressed, expanded outwards in the radial direction and damaged is avoided, the strength of the pier and the boss on the bottom face of the bridge is improved by the thick neck sleeves, the condition that the pier and the boss on the bottom face of the bridge are both pressed and then subjected to edge breakage is avoided, the hoops are matched with the nylon sleeves, thus the elastic rubber column is flexibly connected with the pier and the bridge, and transmission of radial force is blocked.
