Abstract
Description
Technical Field
[0001] The invention relates to the technical field of seismic isolation, in particular to an anti-swaying oblique three-dimensional seismic isolation system. Background Art
[0002] The type of three-dimensional seismic isolation currently used in engineering is mainly assembled with a single support. A single assembled support contains vertical seismic isolation and horizontal seismic isolation. However, compared with horizontal seismic isolation supports, vertical seismic isolation supports are larger in size and occupy more space. In the process of implementing building seismic isolation, they are not conducive to the distribution of supports and do not have anti-sway functions. Existing three-dimensional seismic isolation is usually achieved through a single assembled support. Ordinary three-dimensional seismic isolation supports do not have good anti-sway performance. When a building or large equipment vibrates, the system will be subjected to different forces in the horizontal and vertical directions. The horizontal force and the vertical force will be coupled, causing the seismic isolation system to sway. When swaying occurs, a strong anti-sway component is required to avoid damage to the seismic system. Summary of the invention
