Abstract

The invention discloses a method for demolishing a building or building components based on the resonance principle. The method is characterized by comprising the technological steps that after the building or building component ancillary facilities are demolished, the distance between supporting facilities is measured, the natural vibration frequency of the building or building components is determined, a suitable vibration excitation device is selected according to the natural vibration frequency of the building or building components, the selected vibration excitation device is installed in the quality or rigidity center, the frequency of the vibration excitation device is adjusted to be equal to or approximate to the natural vibration frequency of the building or building components so that mechanical resonance of the building or building components can be achieved, and accordingly the building or building components can be demolished. The method for demolishing the building or building components is safe, economical and environmentally friendly, and the device can be recycled.

Description

technical field [0001] The invention relates to the field of engineering technology, in particular to a method for dismantling buildings or building components by utilizing the principle of resonance. Background technique [0002] At present, with the acceleration of urbanization and the increase of enterprise technology upgrading and transformation projects, the number of abandoned buildings or building components that need to be demolished is increasing day by day. The types of building structures to be demolished have also developed from simple structures such as brick and wood to hybrid structures, frame structures, and even frame-shear structures. At present, the most commonly used demolition techniques in China include mechanical strong demolition method and blasting method. There are many problems in these methods: 1) The noise and vibration generated will interfere with the lives of nearby residents, and also have a great impact on the production of precision proces...
