Seismic isolation support capable of realizing annular horizontal limiting
The invention discloses a seismic isolation support capable of realizing annular horizontal limiting. The seismic isolation support is characterized in that a seismic isolation rubber pad is sleeved with an annular rubber pad, a plurality of rolling blocks are arranged at the top of the annular rubber pad, and the annular rubber pad is fixedly connected with a lower support steel plate and is a cylinder with a conical through hole; each rolling block comprises a ball and a lump ball groove with a top opening, and the ball is embedded in the lump ball groove, the top surface of the ball is exposed out of the opening and does not separate from the lump ball groove; the plurality of rolling blocks are evenly arranged, embedded and fixed in the annular rubber pad along the annular surface and are exposed out of the top surfaces of the balls. Compared with the prior art, the seismic isolation support has the advantages that shear deformation capacity at any angle in the horizontal direction is controlled, the stress area of the support is increased, the condition that the seismic isolation rubber pad is sheared to be damaged due to local height limiting is avoided, the support is simple in structure and convenient to install, and the problem that the horizontal displacement of the seismic isolation support exceeds the limitation is better solved.
