Subway assembly type lightweight concrete baffle damping and limiting device

The utility model discloses a metro assembly type lightweight concrete baffle damping and limiting device which comprises a plurality of prefabricated lightweight concrete columns and a plurality of layers of arc-shaped plates, rubber spring combined supports are arranged below the lightweight concrete columns, limiting grooves are formed in the two sides of the lightweight concrete columns, the arc-shaped plates are inserted into the limiting grooves, and the rubber spring combined supports are connected with the arc-shaped plates. According to the utility model, the lightweight concrete is adopted, so that the material weight is light, the operation is convenient, and the probability of disasters such as easiness in damage due to long-term resonance of the baffle plate, loud subway noise and the like is reduced; longitudinal adjacent arc-shaped plates are in lap joint in a buckled mode, the height of each layer is in lap joint from large to small in an equal proportion mode from bottom to top, and the two t
