Abstract
The utility model discloses a shock insulation rubber support which comprises a base plate (1) and a top plate (2). A rubber cushion (3), a middle steel linear plate (4), a teflon plate (5) and a stainless steel sliding plate (6) are arranged between the base plate (1) and the top plate (2). The base plate (1) is connected with the top plate (2) through a horizontal lead rod (702), the top plate (2) is connected with the middle steel linear plate (4) through a vertical lead rod (701), and a reset spring (9) is arranged between the middle steel linear plate (4) and the top plate (2). When vertical tension and transverse shear force are produced in the process of an earthquake, the horizontal lead rod between the base plate and the top plate can offset the vertical tension and partial transverse shear force on the basis of keeping the integrity of the support, and therefore vertical displacement is limited. The vertical lead rod between the top plate and the middle steel linear plate can offset partial shear force, and due to the fact that the shear transformation of the lead rods needs to consume energy, the effect on a bridge on the upper portion of the support from the earthquake can be reduced.
