A small viscous damper

Abstract

The invention discloses a small viscous damper which comprises a damping box body, a connection plate and shearing plates, wherein the top of the damping box body is provided with an opening, the bottom of the damping box body is provided with a connection bottom plate connected with a lower layer building structure, a plurality of adjustable baffles are inserted on the two sides of the inner wall of the damper, a plurality of shearing areas which are vertically arranged can be formed on the two sides of the interior of the damping box body, and the shearing areas are filled with damping filler; the upper end of the connection plate is provided with a connection top plate connected with the upper layer building structure, and the lower end of the connection plate penetrates through the opening and is inserted into the damping box body; the first end of each shearing plate is connected with the connection plate, and the second end of each shearing plate is inserted into the damping filler in the shearing areas. According to the small viscous damper, multiple layers of the shearing plates are inserted into the damping box body through the connection plate, multiple layers of shearing faces are formed, and larger damping force is guaranteed under the situation that the appearance size of the damper is reduced.

Description

technical field [0001] The invention relates to the field of viscous damper design, in particular to a small viscous damper. Background technique [0002] The viscous damper is a kind of damper that moves a steel plate in a closed high-viscosity damping fluid (polymer), which causes the damping fluid to shear and deform to generate a viscous damping force. It is effective from small to large displacements. , Good cycle performance, good reset after earthquake and other technical characteristics, the direction of energy consumption is the plane direction. Through reasonable design, it can effectively absorb the seismic energy input into the structure and protect the safety of the main structure. It is not only suitable for the shock absorption design of new buildings, but also for the seismic reinforcement and post-earthquake repair of buildings. [0003] However, the traditional viscous damper has the following defects: the interlayer velocity of the steel plate is limited,...

AI Technical Summary

Problems solved by technology

[0003] However, the traditional viscous damper has the following defects: the interlayer velocity of the steel plate is limited, and a large steel plate area is required to increase the damping force, resulting in a larger damper volume and a larger installation space; the interlayer displacement of the structure Limited, which limits the energy dissipation capacity of the damper; the damping force cannot be adjusted
