Steel support with self-reset function

The invention belongs to the technical field of bridge and building vibration reduction and isolation, and relates to a support, in particular to a steel support with self-reset function. The steel support with self-reset function comprises an upper support plate, a middle lining plate and a lower support plate, and the intermediate lining plate is arranged between the upper support plate and thelower support plate; the steel support with self-reset function also comprises a limiting plate and a steel elastomer elastic device; the four sides of the upper support plate are provided with limiting plates, and the four sides of the lower support plate are correspondingly connected with the limiting plates around the upper support plate through the horizontally extensible steel elastomer elastic device. The limiting plates are arranged on the front, rear, left and right four directions of the upper support plate in the horizontal direction and the front, rear, left and right four directions of the lower support pl
