Sealing plate and sealing hole viscous damper

Abstract

The invention provides a sealing plate and sealing hole viscous damper. The sealing plate and sealing hole viscous damper mainly comprises a main cylinder, a guide rod, a main cylinder connection lug ring, an auxiliary cylinder connection lug ring, an auxiliary cylinder, auxiliary cylinder end plates, auxiliary cylinder built-in sealing plates, sealing plate connection ribs, a main cylinder division cavity, an auxiliary cylinder division cavity, a main cylinder end plate, viscous liquid, a sealing ring, a polyurethane oil seal, a resetting spring, fine sealing hole channels and the like, and is characterized in that the auxiliary cylinder mainly comprises two auxiliary cylinder end plates and a plurality of auxiliary cylinder built-in sealing plates; the auxiliary cylinder built-in sealing plates are arranged in parallel and are connected with one another through the guide rod and the sealing plate connection ribs; the fine sealing hole channels are formed in the auxiliary cylinder built-in sealing plates; pressure limiting valves are arranged on the auxiliary cylinder end plates; the auxiliary cylinder is connected with the main cylinder through a spring; and the sealing ring and the polyurethane oil seal are arranged on one side of the guide rod. The sealing plate and sealing hole viscous damper has the effects and the advantages of large damping force, high initial rigidity, high reliability and stability, simplicity in manufacturing and mounting and convenience in use and can be applied to earthquake resistant design of new building engineering and reinforcement and maintenance of existing engineering.

Description

technical field [0001] The invention relates to a vibration control device for a building structure, in particular to a viscous damper with dense plates and dense holes for building structure vibration control. Background technique [0002] Earthquake disasters are sudden and devastating, which seriously threaten the safety of human life and property. Nearly a thousand destructive earthquakes occur every year in the world, and a major earthquake can cause hundreds of billions of dollars in economic losses, resulting in hundreds of thousands of deaths or serious injuries. my country is located in the two most active seismic belts in the world, and is one of the countries that suffered the most serious earthquake disasters. The casualties caused by the earthquake rank first in the world, and the economic loss is also very huge. The massive destruction and collapse of buildings in earthquakes is the direct cause of earthquake disasters. When an earthquake occurs, ground vibra...

Problems solved by technology

[0003] At the beginning of the 20th century, the seismic calculation method proposed by Professor Omori Fangyoshi and the seismic coefficient method proposed by Dr. Sano Toshiki did not consider the dynamic characteristics of the structure. Later, it was called the static theory of seismic design. Rigid building structure, that is, "rigid structural system", but this kind of structural system is difficult to realize, and it is not economical. Only a very small number of important buildings adopt this structural system

However, on the other hand, due to the increase in the number of mechanical parts, the reliability decreases, and the possibility of problems such as failures increases
