Embodiment Construction

[0025] Such as figure 1 As shown, the present invention includes a protective shell 9 with one end being an open end and the other end being a closed end. The closed end of the protective shell 9 is externally connected with a connecting piece 10 for connecting an anti-seismic control damper. The open end of the protective shell 9 The mouth end is inserted into a sliding guide rod 1 with one end inserted into the protective shell 9 and the other end exposed outside the protective shell 9 and capable of reciprocating movement inside the open end of the protective shell 9. The sliding guide rod 1 is inserted into the protective shell 9. One end inside the open end is fixedly connected with a slider 6 capable of reciprocating movement inside the protective case 9 , and the inner wall of the middle part of the protective case 9 is provided with a slider for limiting the reciprocating position of the slider 6 Positioning rib 7, between the slider 6 and the closed end of the protect...

Abstract

The invention discloses a large deformation protector for anti-seismic control damper. The large deformation protector comprises a protecting shell with an open end and a closed end. A connection is connected to the outside of the closed end of the protecting shell. A sliding guide rod is inserted in the open end of the protecting shell and does reciprocating motion in the same. One end of the sliding guide rod is inserted in the protecting shell, and the other end of the sliding guide rod is exposed out of the protecting shell. The end, inserted in the open end of the protecting shell, of the sliding guide rod is fixedly connected with a slide block doing the reciprocating motion in the protecting shell. The middle inner wall of the protecting shell is provided with slide block positioning ribs used for limiting the slide block. An Austenitic shape memory alloy wire is arranged between the slide block and the protecting shell and applied with prestress Sigma p. One end of the Austenitic shape memory alloy wire is connected with the slide block, and the other end of the Austenitic shape memory alloy wire is connected with the closed end of the protecting end. The large deformation protector is unique in construction, novel and reasonable in design, effective in protecting the anti-seismic control damper from failure, reliable in performance and bright in application prospect.

Description

technical field [0001] The invention belongs to the technical field of anti-seismic control of civil engineering structures, and in particular relates to a large deformation protection device for an anti-seismic control damper. Background technique [0002] With the increasing span and height of buildings and the increasing complexity of structures, it is difficult for engineering structures designed according to traditional design methods to completely avoid damage and destruction under the action of strong earthquakes. Suppressing the structural dynamic response caused by external dynamic loads through vibration control technology is an effective means to improve structural safety. Among them, the application of passive anti-seismic control technology is more common, such as the application of various dampers for passive anti-seismic control of structures. However, neither the research field nor the engineering application considers how to ensure that the damper can still...
