Abstract
Provided is a damping device including a cylindrical body sealed with an inner cover and an outer cover at both ends, a support rod coupled to one end of the cylindrical body to perform an axial motion, the support rod including a moving plate having a damping orifice in the cylindrical body, the support rod including a nut configured to adjust a length of the support rod at an inner side end received in the cylindrical body, and a buffering device configured to store elastic energy in one of a first spring and a second spring based on a moving direction of the moving plate, the buffering device including the first spring inserted in the inner cover, the second spring inserted in the outer cover, and a lubricant in the cylindrical body.
Claims1
A damping device for building seismic reinforcement, the damping device comprising:
- a cylindrical body sealed with an inner cover and an outer cover at both ends;
- a support rod coupled to one end of the cylindrical body to perform an axial motion, the support rod comprising a moving plate in the cylindrical body, the support rod comprising a nut configured to adjust a length of the support rod at an inner side end received in the cylindrical body;
- and
- a buffering device configured to store elastic energy in one of a first spring and a second spring based on a moving direction of the moving plate, the buffering device comprising the first spring disposed between the inner cover and the moving plate, the second spring disposed between the outer cover and the moving plate, and a lubricant in the cylindrical body.
