Anti-bias combined rubber damping support

The utility model relates to the technical field of anti-seismic technology of bridge engineering, in particular to an anti-bias combined rubber damping support which comprises a square body, the interior of the body is hollow, an arc-shaped protective crown is arranged outside the body, a plurality of rubber layers are arranged in the body at intervals, and the rubber layers are arranged in the body. The plane where the rubber layers are located is parallel to the lower surface of the body, stiffening steel plates are connected to the upper surface and the lower surface of each rubber layer, a functional layer is formed between every two adjacent rubber layers, a friction plate set is arranged in each functional layer, and each friction plate set comprises a sliding steel plate and a polytetrafluoroethylene sliding plate which are sequentially stacked from bottom to top. The protective crown comprises an upper protective crown which is connected to the center of the upper surface of the body. The protective
