A soft collision energy dissipation device

Abstract

The application discloses a soft collision energy dissipation device, which includes a pressure-bearing component, a fixed component, a sliding component, and an energy dissipation component. The fixed component includes a base and a limiting component. It is fixed on the base and is movably connected with the sliding part. The pressure-bearing part can drive the sliding part to reciprocate relative to the friction plate in the extending direction of the base. The elastic part is arranged between the sliding part and the limiting part. The elastic part is connected with the limiting part and Connected with the sliding member, when the sliding member moves relative to the friction plate, the elastic member can drive the sliding member to move back. The energy dissipation device in this application is composed of two energy dissipation parts, one part is formed by the friction between the sliding part and the friction plate, and the other part is formed by the damping effect of the elastic part between the sliding part and the limiting part. The function transforms the rigid action between the base isolation structure and the pressure-bearing parts into a flexible action, prevents excessive deformation of the base isolation structure, and forms a protective effect on the building.

Description

technical field [0001] The present application relates to the technical field of building anti-seismic technology, in particular to a soft collision energy dissipation device. Background technique [0002] Earthquakes are one of the more common natural disasters in people's lives. There are more than 5 million earthquakes every year on the earth, that is, tens of thousands of earthquakes every day. Most earthquakes are too far or too small for people to feel, but There are still about ten or twenty earthquakes that cause serious harm to human beings. When an earthquake occurs, houses will collapse and cause a large number of casualties. Even minor earthquakes will cause damage to houses in varying degrees. The study found that seismic waves include longitudinal waves and shear waves, among which the shear waves play a major role in destruction.

Problems solved by technology

[0003] In modern cities, office buildings, residential buildings, etc. pay more and more attention to seismic isolation technology. According to the research on the occurrence of earthquake disasters, under the action of near-fault velocity pulse earthquakes, earthquake-isolated buildings may experience excessive displacement. As a result, severe rigid collisions with the surrounding retaining walls or rigid limit members will result in damage to the upper building structure
