Abstract

The invention provides a piezoelectric telescope-feed tension compression bidirectional stress initiative anti-seismic control device, comprising an external tube, a fastening force changing nut arranged at the upper part of the external tube and a first connecting rod penetrating the fastening force changing nut; a second connecting rod is arranged at the lower part of the external tube; an internal tube in hollow structure is arranged in the external tube, and piezoelectric pile is placed in the internal tube; the upper end of the internal tube is fixedly connected with the fastening force changing nut by a bolt; a first transmission end plate is arranged between the upper end part of the internal tube and the upper end part of the piezoelectric pile; a second transmission end plate provided with a hinge is arranged between the lower end part of the internal tube and the lower end part of the piezoelectric pile; and the inner side at the lower end of the external tube is provided with a lug which is contacted with the hinge of the second transmission end plate in moving process. The invention solves the technical problem that anti-seismic control device is low in working efficiency and has the advantage of strong adaptability to environment.

Description

technical field [0001] The invention relates to the field of anti-seismic control of civil engineering, in particular to a piezoelectric sleeve-type active anti-seismic control device for tension and compression bidirectional force. Background technique [0002] With the increase in span, height and structure of buildings, higher requirements are placed on the safety and comfort of structures. Eliminating or reducing the influence of unfavorable factors through control technology has attracted more and more attention from designers. Among them, the application of passive and semi-active control technology in civil engineering has been well researched and applied, and it relies heavily on the driving The active control technology of the device is greatly limited due to factors such as slow response, small output, and small stroke of the traditional vibration control drive device. The traditional active anti-seismic control drive device can usually only achieve unidirectional...
