The shock isolation system consists of a T-shaped wood column, three steel ball crown pieces, three concave spherical surface limit edge column foundation stones, a graphite-doped steel ball layer and three annular toughened glass sealing plates. The T-shaped wood column is composed of three column limbs formed by connecting four round woods through square wood ladder lattices and bamboo plywood. The steel spherical crown part is formed by welding a steel spherical crown, an annular steel cover plate, a steel plate circular hoop and a circular steel pipe. The graphite-doped steel ball layer can reduce friction force between the steel ball crown and the spherical surface of the column foundation Dan Ao. The concave spherical surface of the column foundation stone can enable the post-earthquake T-shaped wood column to reset automatically, and the limit edge of the column foundation stone can limit the excessive displacement of the bottom of the T-shaped wood column in the vibration process. The annular toughened glass sealing plate can be sealed and waterproof. The shock isolation system has the advantages of reducing the earthquake action of the upper structure by the shock isolation at the bottom of the T-shaped wood column and realizing structural toughness and shock resistance by self-resetting after the earthquake.
