Assembled lead shear damper

Abstract

The invention provides an assembled lead shear damper, which is easy to assemble and has stable performance. The damper comprises a middle pulling plate, an end part connection plate, a lead column, a first inner layer pulling plate and a second inner layer pulling plate; the first inner layer pulling plate and the second inner layer pulling plate are positioned on both sides of the middle pulling plate and both sides of the end part connection plate; a middle layer lead column hole and a middle layer pin hole are formed on the middle pulling plate; the first inner layer pulling plate and the second inner layer pulling plate form an inner layer pulling plate; the inner layer pulling plate comprises an inner layer pulling plate main body on which an inner layer lead column hole and an obround limiting hole are formed; the inner layer lead column hole is positioned at one end of the inner layer pulling plate main body; the other end of the end part connection plate is connected with the inner layer pulling plate main body; a connection pin is arranged in the middle layer pin hole of the middle pulling plate and passes through the obround limiting hole of the inner layer pulling plate; the inner layer lead column hole is coaxial with the middle layer lead column hole; and the lead column is positioned in the inner layer lead column hole and the middle layer lead column hole. By changing of a shear area of the lead column, such as increasing of the diameter or the number of shear surfaces of the lead column, output force can be increased.

Description

technical field [0001] The invention is an assembled lead shear damper, which consumes structural system energy by setting an effective lead column shear plane, and plays the role of energy dissipation and shock absorption (vibration) on the structure. Due to the effectiveness of lead energy dissipation, the assembled lead shear damper can be widely used in energy dissipation supports of building structures, bridge shock absorption, etc. Background technique [0002] Energy dissipation and shock absorption (vibration) technology is an effective structure control technology. It installs energy dissipation and shock absorption (vibration) devices at appropriate positions in the structure to reduce the dynamic force of the structure under the action of earthquake, strong wind or other dynamic loads. response. Lead damper is an effective damper widely used in shock absorption of engineering structures. The common ones are lead extrusion type and lead shear type. In recent yea...

AI Technical Summary

Problems solved by technology

figure 1 The disadvantage of the lead squeeze damper shown is that the process of filling the closed cavity with lead is relatively complicated; figure 2 The disadvantage of the lead shear damper shown is that it is difficult to effectively connect the lead post to the sliding plate and the upper and lower cover plates

[0005] According to the characteristics of the existing lead damper, the present invention constructs a new type of assembled lead shear damper, which largely solves the problems of complex lead filling process and complicated connection of lead columns.
