A center-fixed rotary energy-dissipating connector

Abstract

The invention provides a center-fixed rotary energy-consuming connector functioning in member connection and reduction of influence of displacement among members in prefabricated building structures. The center-fixed rotary energy-consuming connector comprises a fixed plate connected with a left building member, a moving plate connected with a right building member, a rotary plate, shearing-type metallic energy-consuming materials, a viscoelastic energy-consuming material attached into the fixed plate, a viscoelastic energy-consuming material attached into the moving plate, a high-strength bolt for connecting the fixed plate with a central screw hole of the rotary plate, and a high-strength bolt for connecting the moving plate with an eccentric screw hole of the rotary plate. When relatively small displacement is generated among the building members under exogenic action of the building, in other words, when relatively small displacement is generated between the fixed plate and the moving plate, the rotary plate is driven through the high-strength bolt on the moving plate so as to rotate by taking the central axis of the bolt hinged to the fixed plate as a rotation center, amplified displacement is reflected on two relative movement surfaces of the energy-consuming materials, and accordingly the energy-consuming materials yield and consume energy.

Description

technical field [0001] The invention is mainly used in prefabricated buildings, as an element connected between prefabricated components, and plays an energy-dissipating role when relative displacement occurs between components. Background technique [0002] The basic principle of shock absorption in engineering structures is to use special shock absorbing components or devices to make them enter the plastic state first under strong earthquakes to generate damping, thereby consuming the energy input into the building structure system, reducing the dynamic response of the structure, and better 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. [0003] Prefabricated reinforced concrete structures offer many advantages: speed of construction, high build quality, low project cost, sustainability, an...

Problems solved by technology

At the same time, the existing energy-dissipating devices occupy a large space or require a more complex support system, which affects the space use efficiency of the building and also affects the overall stiffness of the structure, which is limited in practical applications.
