A displacement and velocity amplification device and a damping structure

Abstract

The application provides a displacement and speed amplification device and a damping structure, which is applied to a damper for energy dissipation by interlayer shear deformation, and comprises a shell, a first sliding block for connecting a building structure and a second sliding block for connecting the damper, wherein the shell comprises a back plate, a connecting piece and a cover plate, the first end of the connecting piece is vertically fixed to the back plate, the connecting piece is provided with a first oil groove and a second oil groove which are in communication with each other and are arranged at intervals along a second direction; the cover plate is arranged on the second end of the connecting piece; the two ends of the first sliding block along a first direction are respectively sealed and slidingly connected to the first oil groove; the two ends of the second sliding block along the first direction are respectively sealed and slidingly connected to the second oil groove; and the cross-sectional area of the first oil groove perpendicular to the first direction is greater than that of the second oil groove. The displacement and speed amplification device provided by the application can make the damper enter an energy dissipation working state in advance and reduce the damage of the building structure.
