Under the same load condition, the vertical bearing section dimension of the bearing body of the No. 1 and No. 2 supports is 1/2-7/10 of the vertical bearing section dimension of the bearing body of the existing laminated rubber vibration isolation support.

The utility model has the advantages as follows: the invention provides a self-resetting sliding shock insulation support arranged between an upper buttress and a lower buttress of a building. Because the vertical bearing main body adopts a steel structure and polytetrafluoroethylene or modified high-density polytetrafluoroethylene as main body materials, the vertical design load is 20-50 Mpa, the vertical section size of the vertical bearing main body of the support is greatly reduced and is only 1/2-3/10 of the vertical section size of the laminated rubber shock-insulation support main body with the same vertical load, stainless steel plates are respectively welded on the top surface of the lower seat plate and the bottom surface of the upper seat plate of the support bearing main body, the upper seat plate and the lower seat plate slide relative to the support bearing main body in sequence, the static friction force and the reset spring of the sliding friction pair provide initial rigidity, and the dynamic friction force plays a role in damping and consumes seismic energy. The reset rubber spring on the self-reset sliding shock insulation support provides the horizontal rigidity of the whole shock insulation system, the shock period of the building is prolonged, and meanwhile, the shear force of the reset rubber spring enables the building to recover the original position after the earthquake.
