Title:
LOCAL RESONANCE-TYPE BUILDING VIBRATION ISOLATION FOUNDATION
Document Type and Number:
WIPO Patent Application WO/2023/124039
Kind Code:
A1
Abstract:
Disclosed in the present invention is a local resonance-type building vibration isolation foundation. The building vibration isolation foundation is composed of local resonance-type wave resistance units forming a topology in a single direction, a plane direction or a space direction, wherein the local resonance-type wave resistance unit successively comprises, from inside to outside, a rigid core body, an elastic wrapping layer and a bearing capacity outer frame. In the present invention, a special design is performed on a building foundation by using a local resonance-type phononic crystal bandgap theory, and a geometric size and a material composition of a structure are changed, such that the active adjustment and control of a bandgap and a vibration isolation frequency band can be realized, and a micro-vibration control objective is achieved while a bearing function is realized.
