Problems solved by technology

[0002] At present, the seismic isolation bearings used in engineering are mainly used to reduce the horizontal seismic action, but the effect of this type of seismic isolation bearing on reducing the vertical seismic action or vertical vibration of the upper structure is not obvious
In addition, due to the vertical vibration caused by rail traffic, ordinary seismic isolation bearings cannot effectively reduce vertical vibration and reduce noise pollution, so it will affect the comfort of the superstructure and surrounding buildings, and even affect normal use.
Many designers at home and abroad have also proposed the concept and structure of three-dimensional bearings based on springs, which can reduce the vertical vibration caused by earthquakes and vertical vibrations caused by vehicles, mechanical equipment, etc., but there are few practical applications at present.

Abstract

The invention relates to the technical field of civil engineering, in particular to a multi-dimensional shock / vibration isolation sliding plate support. Comprising a vertical vibration isolation unit and a horizontal sliding unit which are connected with each other. The vertical vibration isolation unit and the horizontal sliding unit are connected through a middle upper connecting plate and a middle lower connecting plate. The vertical vibration isolation unit and the horizontal sliding unit are organically combined to form the slidable multi-dimensional shock / vibration isolation sliding plate support, horizontal and vertical earthquakes or vibration are isolated at the same time, and the multi-dimensional shock / vibration isolation sliding plate support is suitable for solving the influence of rail transit vibration and the like on an upper structure or a transportation hub in a high-intensity area.
