Scissor-type deformation amplifying device for amplifying energy consumption effect of damper
The invention relates to a scissor-type deformation amplifying device for amplifying the energy consumption effect of a damper. The device is arranged in a framework composed of a left structural column, a right structural column, an upper beam and a lower beam; the device comprises a damper, a first support, a second support, a third support, a fourth support, a cover plate and an instability prevention plate, wherein the upper end of the cover plate is welded below the first support and the second support, the middle part of the cover plate is hinged with two ends of the damper through movable shafts, the lower end of the cover plate is welded together with the upper end of the instability prevention plate, and the lower end of the instability prevention plate is welded together with the third support and the fourth support. Compared with the prior art, the scissor-type deformation amplifying device has the advantages that the displacement of the damper can be amplified to more than 2 times of the inter-story displacement, the energy consumption of the damper can be increased, and the additional damping ratio of the structure under the actions of wind load and earthquake can be increased; in addition, the out-of-plane stability of the device, caused under the action of rare occurrence earthquake, is avoided by using a construction measure, and the safety of the structure under the action of the rare occurrence earthquake is ensured.
