A high-efficiency space-utilizing damper for a secondary displacement amplifying device directly supported at the end

Abstract

The invention discloses an efficient space-use type damper of an end portion straight brace secondary displacement amplification device. The efficient space-use type damper of the end portion straightbrace secondary displacement amplification device comprises a vertical type moving displacement support, a T-shaped overhanging positioning bracket, a T-shaped connecting plate, a displacement amplification rod, an input rod with a rack, a duplicate gear, an output rod with a rack, a damper connecting piece, an input end guide gear, a damper device, a damper fixing support and the like. The efficient space-use type damper of the end portion straight brace secondary displacement amplification device performs first amplification on the relative displacement between layers of a building throughthe displacement amplification rod when the deformation of the building structure is small or slow, then the displacement of the first amplification is subjected to second amplification through the duplicate gear, two-time amplification is performed, so that the damper generates greater relative displacement, the damper generates greater damping force, and the better shock absorption effect is achieved. At the same time, the efficient space-use type damper has the characteristics of simple structure, considerable cost, convenient installation, convenient operation, flexible layout, firm and durable and the like, and has broad prospects of development and application.

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 high-efficiency space utilization type direct support secondary displacement amplification damper device. Background technique [0002] The basic principle of shock absorption in engineering structures is to use special shock-absorbing components or devices to make them first enter the plastic state under the action of strong earthquakes to generate damping, thereby consuming the energy input into the building structure system, reducing the dynamic response of the structure, and more It is an effective, safe and economical engineering shock absorption technology to ensure the safety of the main structure. For this reason, technicians at home and abroad have developed and developed many types of damping devices. With the increase of the span of the building structure, the increase of the height and the increasing complexi...

Problems solved by technology

The present invention transmits the relative displacement of the upper floor to the displacement amplifying rod through the vertical displacement moving support and the fixed connection between the upper floor beam through the bolts, and through the first amplification of the displacement amplifying rod, it makes The small relative displacement between the layers has been amplified for the first time, and the displacement amplification lever further amplifies the first amplified displacement through the double linkage gear, thus realizing the second displacement amplification and improving the existing The damper has the disadvantage that the amplification effect of the damper is not significant in the small interlayer displacement. A total of two displacement amplifications have been carried out, so that the damper produces a larger relative displacement, and the damper produces a greater damping force, so as to achieve a better performance. shock absorption effect
