Abstract

The invention provides a viscous damper comprising swingable umbrella type blades, the viscous damper is mainly applied to vibration control of building structures, and belongs to the technical fieldof structural vibration control. The viscous damper comprises a damping cylinder body, a cover plate, a dowel bar, a supporting rod fixing device, a supporting rod, a square blade plate, damping liquid, a hinge device A, a hinge device B, a hinge device C, a blade plate fixing device and a connecting device. When an external structure connected with the damper vibrates, the dowel bar is driven tomove axially, due to the fact that the supporting rod fixing device is fixed to the cover plate and the blade plate fixing device is fixed to the dowel bar, the dowel bar drives the blade plate fixingdevice to move together, and then the square blade plate paddles in the damping liquid under the action of the supporting rod, so that vibration reduction and energy dissipation are achieved throughcounter-acting force given by the damping liquid in the paddling process. The viscous damper is novel and clear in structure and is a safe and efficient damper.

Description

technical field [0001] The invention relates to a viscous damper including swingable umbrella-shaped blades, which is mainly used in the vibration control of building structures and belongs to the technical field of structural vibration control. Background technique [0002] In recent decades, there have been several extremely dangerous earthquakes all over the world, which have brought huge losses of life, economy and property to the society. At present, with the rapid development of the economy, the shock absorption technology of building structures is also constantly improving. More and more shock absorption designs have been applied to building structures, and these designs have also achieved good shock absorption effects. [0003] The seismic design of building structures is usually to add energy-dissipating and shock-absorbing components to certain positions of the structure, or to set the structural supports and connectors as energy-dissipating and shock-absorbing com...
