Problems solved by technology

Among them, the cylindrical viscous damper is the most widely used in China, but its working state is generally internal high pressure, and its sealing performance is very high, which leads to its manufacturing difficulty and cost increase, and finally presents a situation of low cost performance; the other is The wall-type viscous damper is made of viscous damping fluid in a high-viscosity state. It works under normal temperature and pressure. The key to the application of wall-type viscous dampers is that the production cost of wall-type viscous dampe

Abstract

The invention discloses a gear double-spiral-type fluid viscous damper. The bottom end of a lower connecting plate is connected with the top end of a lower concrete connecting wall through a lower telescope-feed connecting piece, the top end of the lower connecting plate of the damper is closely connected with the bottom end of a viscous liquid tank with a viscous liquid filler and a communicating vessel inspection window, wherein the viscous liquid tank is welded by steel plates and filled with viscous liquid, and a spiral gear shaft and a stable gear shaft are embedded into the viscous liquid tank; a plurality of energy-consuming blades perpendicular to the rotating direction are welded on the spiral gear shaft, and the top end of a double-faced gear transmission rod is in close contact with the spiral gear shaft through a gear; and the bottom end of the double-faced gear transmission rod is in close contact with the stable gear shaft through a gear, and the double-faced gear transmission rod is connected with an upper concrete connecting wall through an upper connecting piece by adopting an upper telescope-feed connecting piece. According to the gear double-spiral-type fluid viscous damper, the energy-consuming capacity does not depend on structural relative deformation, the performance is stable and efficient, and the gear double-spiral-type fluid viscous damper can be widely used in anti-seismic and wind resistant design of multiple and high-storey buildings.

Description

technical field [0001] The invention relates to a gear double-helix viscous damper, which belongs to the technical field of building energy dissipation and shock absorption. Background technique [0002] Earthquake is a very serious natural disaster. During the earthquake, the surface buildings will be distorted and deformed. When the earthquake is relatively strong, they may even collapse, causing huge economic losses and casualties. In order to reduce earthquake disasters in buildings, energy dissipation technology has received extensive attention. [0003] Viscous dampers are widely used because of their strong energy dissipation capacity, stable performance, and no additional static stiffness for the structure. Among them, the cylindrical viscous damper is the most widely used in China, but its working state is generally internal high pressure, and its sealing performance is very high, which leads to its manufacturing difficulty and cost increase, and finally presents a...
