Technical application of magnetic suspension in filed of vibration prevention of engineering structure

Abstract

The invention relates to buildings, and particularly belongs to technical application of magnetic suspension in the filed of vibration prevention of an engineering structure. The invention adopts the technical proposal that: a plurality of substructures are arranged in the engineering structure, the bottom layers of the substructure are provided with an electromagnet, the lower part of the electromagnet is provided with a corresponding structural electromagnet, the electromagnet and the structural electromagnet after being powered have the same electromagnetic polarity, and the electromagnet and the structural electromagnet are connected with an electromagnetic control device with an earthquake signal receiving device. The technical application has the advantages that: because the engineering structure applied with the magnetic suspension technology fully isolates the earthquake influence, the problems of various assumptions calculated by earthquake action, mutual influence of the earthquake and the structure, and the like disappear; and the structure is not influenced by the strength, properties and the like of the earthquake.

Description

technical field [0001] The invention relates to buildings, in particular to a technical application of magnetic levitation in the anti-vibration field of engineering structures. Background technique [0002] In the prior art, the prevention and control of earthquakes mostly adopts ways of strengthening the strength of buildings or installing rubber and other seismic isolation devices at the bottom of buildings to achieve the purpose of earthquake prevention and control. Although these methods have played a huge role in earthquake prevention and disaster reduction, But it cannot fundamentally eliminate the impact of earthquakes on buildings. For high-rise or ultra-high-rise buildings, due to the characteristics of the building itself, excessive deformation and acceleration are more likely to occur during an earthquake, resulting in damage to engineering structures and internal facilities and casualties.

[0002] In the prior art, the prevention and control of earthquakes mostly adopts ways of strengthening the strength of buildings or installing rubber and other seismic isolation devices at the bottom of buildings to achieve the purpose of earthquake prevention and control. Although these methods have played a huge role in earthquake prevention and disaster reduction, However, it cannot fundamentally eliminate the impact of earthquakes on buildings

For high-rise or super high-rise buildings, due to the characteristics of the building itself, excessive deformation and acceleration are more likely to occur during an earthquake, resulting in damage to engineering structures and internal facilities and casualties.
