Vertical tensile seismic isolation bearing

Abstract

The utility model belongs to civil engineering technical field discloses a kind of vertical tensile isolation bearing, including lower connecting plate and upper connecting plate, lower connecting plate and upper connecting plate are provided with support between, the outer surface of support is provided with limiting unit, the limiting unit includes lower vertical limiting plate and upper vertical limiting plate, the upper vertical limiting plate is fixedly connected with upper connecting plate, the upper end of lower vertical limiting plate is abutted with upper vertical limiting plate, and lower end is fixedly connected with lower connecting plate, when vertical tensile force appears, lower vertical limiting plate and upper vertical limiting plate can effectively limit the vertical deformation of support, prevent support tensile damage, when facing complex earthquake situation, it is more stable and reliable, can continuously play the role of isolation, significantly improve the seismic safety of building, bridge and important facility.
