Embodiment Construction

[0024] The specific implementation manners of the present invention will be further described below in conjunction with the accompanying drawings and technical solutions.

[0025] A center-fixed rotary energy-dissipating connector, including a fixed plate 1, a moving plate 2, a rotating plate 3, a first shear-type metal energy-dissipating material 4, a second shear-type metal energy-dissipating material 5, a first adhesive Elastic energy-dissipating material 6 , second viscoelastic energy-dissipating material 7 and bolts 8 .

[0026] The fixed plate 1 is formed by connecting the upper plate, the lower plate and the connecting plate, and one end of the rotating plate 3 rotates in the space formed by the fixing plate 1, and the arc inside the connecting plate is tangent to the arc on the side of the rotating plate 3; the first shear Cut-shaped metal energy-dissipating material 4 is a strip-shaped arc-shaped structure, and the center of the strip-shaped arc-shaped structure is th...

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...
