Building multi-directional self-resetting seismic isolation structure

Abstract

The invention discloses a building multi-directional self-resetting seismic isolation structure which comprises a building, an upper foundation seat and a lower foundation seat. The building multi-directional self-resetting seismic isolation structure is characterized in that the building is fixedly mounted on and connected onto the upper end surface of the upper foundation seat; seismic isolation resetting spherical surface flanges are mounted at the bottom of the upper foundation seat; concave spherical surface multi-directional self-resetting seismic isolation components corresponding to the seismic isolation resetting spherical surface flanges are arranged on the lower foundation seat; the upper foundation seat and the lower foundation seat are connected through vertical restrainers; limiting walls are arranged at a certain distance to surroundings of the building; the upper foundation seat and the limiting walls are connected through horizontal restrainers. According to the building multi-directional self-resetting seismic isolation structure, the original structure stress as well as load-carrying members and foundation of the building self are utilized fully, a seismic isolation mechanism layer is formed by the seismic isolation resetting flanges and the concave spherical surface multi-directional self-resetting seismic isolation components arranged between the upper foundation seat and the lower foundation seat in housing constructing stage can effectively play actions of seismic isolation and earthquake energy absorption during earthquake and reduces earthquake damage to buildings farthest, and the buildings can be reset to original positions automatically when the earthquake stops.

Description

Technical field [0001] The invention relates to a civil engineering technology, in particular to a multi-directional seismic isolation reset structure of a building that can dissipate earthquake energy to reduce earthquake damage and can automatically return to an initial position after an earthquake. Background technique [0002] With the acceleration of the urbanization process in China, the scale of urban construction is increasing, and the amount of urban buildings is increasing. At the same time, China is a country with frequent earthquakes. Earthquakes seriously threaten the safety of people's lives and property, especially similar In Wenchuan, Sichuan, the Lushan earthquake has brought great economic and even life casualties to people's production and life. An earthquake is a natural phenomenon. An earthquake is a vibration caused by the rapid release of energy from the earth's crust. During this period, seismic waves are generated, which can cause huge damage to the enviro...

Problems solved by technology

[0003] Aiming at the technical defects of complex structure, high cost and inconvenient maintenance of the existing building isolation technology, the present invention provides a multi-directional self-resetting isolation structure for buildings, which can effectively dissipate the seismic wave energy and prevent the seismic wave from being transmitted to The building itself can isolate the seismic wave, thereby reducing the damage caused by the earthquake, and can automatically return to the starting position after the earthquake by its own weight. The whole structure is simple, the cost is cheap, and it is easy to promote
