Prestress rubber support seat

The utility model relates to a prestress rubber support seat, which belongs to the field of structure shock isolation control. The prestress rubber support seat consists of an upper connecting steel plate, a lower connecting steel plate, an inner thin steel plate, an inner rubber layer, a prestress steel stranded wire and an anchor device, wherein the inner thin steel plate and the inner rubber layer are alternately overlapped, and the inner thin steel plate, the inner rubber layer and the outer rubber protective layer are vulcanized together with the upper connecting steel plate and the lower connecting steel plate under high temperature and high pressure, the prestress steel stranded wire are arranged insideand are connected with the upper connecting steel plate and the lower connecting steel plate through the anchor device. The prestress rubber support seat overcomes the defect of insufficient tensile intensity through high pressure and load resistance capability of the rubber support seat, the pressure prestress is exerted in advance before the support seat bears the load, the support seat is maintained at the pressed state or the small tensile stress state under the condition of seldom occurred earthquake, and the safety of the shock isolation structure can be ensured. The support seat has the advantages of simple structure and clear shock isolation mechanism, and is applicable to the shock isolation control of tall buildings, large-span bridges and other large-scale buildings with high shock resistance performance requirements.
