Abstract

The invention relates to a novel sucker and spring type energy dissipation damper. The novel sucker and spring type energy dissipation damper comprises a steel rod arranged between two vertical pillars. The two ends of the steel rod are connected with elastic connectors and rubber suckers, and the elastic connectors are sleeved with the rubber suckers. The vertical pillars are provided with rubber sealing surfaces, and the rubber suckers are adsorbed to the rubber sealing surfaces. The two ends of each elastic connector are connected with the corresponding vertical pillar and the inner side of the corresponding rubber sucker through fixing mechanisms. The energy dissipation damper integrates spring type energy dissipation and sucker type energy dissipation, and adopts two connecting modes, namely connection between the springs and the vertical pillars and connection between the rubber suckers and the rubber sealing surfaces on the vertical pillars. The two connecting modes work at the same time under the action of earthquake loads, and the energy generated by an earthquake can be more effectively absorbed through the co-action of the inside and outside air pressure difference of the vacuum suckers and the pulling and pressing of the springs.

Description

technical field [0001] The invention relates to an energy dissipation and shock absorbing device, in particular to a novel sucker spring type energy dissipation damping. Background technique [0002] The dampers currently used in buildings are common: metal energy dissipation dampers, frictional energy dissipation dampers, viscoelastic or viscous dampers. Metal energy-dissipating dampers use different forms of elastic hysteretic deformation of metals to consume energy. The disadvantages are that they have a large space occupation rate, low space utilization rate, high cost, and are not easy to replace. The frictional energy dissipation damper uses the friction force generated by the relative sliding between two solids to consume energy. Most frictional energy dissipation dampers cannot change their own characteristics according to the control needs, and their control force on the structure is completely restricted by the structure. Motion, a friction damper that can slide u...
