Abstract

The invention relates to a multilayer damper with a displacement amplifying device. The multilayer damper comprises a lever, outer steel plates, at least one inner steel plate, at least two movable steel plates, connecting steel plates, fulcrum shafts and a damping material, the outer steel plates are fixedly connected with a lower-layer floor beam, the inner steel plates are disposed in inner cavities of the outer steel plates and connected with the outer steel plates to form a whole, number of the movable steel plates is constantly larger than that of the inner steel plates, the movable steel plates are connected into a whole and connected among the inner steel plates in an inserted manner, the damping material is positioned among the outer steel plates, the movable steel plates and the inner steel plates, the upper portions of the movable steel plates are hinged to one end, larger in length, of the lever, the fulcrum shafts of the lever penetrate fulcrum hole grooves of the outer steel plates and are tangential with the inner faces of the fulcrum hole grooves, and one end, smaller in length, of the lever is hinged to the connecting steel plates which are fixedly connected with an upper-layer floor beam. The lever displacement amplifying device and number of layers of the damping material are increased to amplify relative displacement and damping coefficient of the damper so as to enable the damper to generate larger damping force.

Description

technical field [0001] The invention relates to a multi-layer damper with a displacement amplifying device. Background technique [0002] The speed and displacement of the existing damper during work are equal to the relative speed and relative displacement of the connection point. If the relative velocity and relative displacement of the connection points are small, the damper cannot provide sufficient damping force. In order to increase the output of the damper, the existing damper is often realized by increasing the size of the damper, which not only increases the construction cost, but also affects the use function of the building. Contents of the invention [0003] In view of the defects in the prior art, the object of the present invention is to provide a multi-layer damper with a displacement amplifying device, which can amplify the relative displacement and damping coefficient of the damper, thereby generating greater damping force. [0004] To achieve the above ...
