Abstract

The invention relates to the field of civil engineering, and particularly relates to a support capable of achieving seismic reduction and isolation of buildings, and particularly relates to a slidablemulti-dimensional seismic-vibration double-control seismic isolation support. The support comprises a vertical seismic isolation unit and a horizontal sliding unit which are connected with each other, wherein the vertical seismic isolation unit comprises a plurality of belleville spring sets or / and a plurality of spiral spring sets, a sliding pair of the horizontal sliding unit is composed of afriction material plate and a sliding panel, and the friction material plate and a middle lower connecting plate are supported by a component arranged by a laminated rubber steel plate; meanwhile, thesupport has the seismic-vibration double-control capacity of isolating horizontal and vertical earthquakes or vibration; and the support is simple in structure, good in energy consumption effect, lowin manufacturing cost, convenient to install and suitable for engineering structures with seismic-vibration double-control requirements.

Description

technical field [0001] The invention relates to the field of civil engineering, and relates to a support capable of realizing shock absorption and isolation of buildings, in particular to a slidable multi-dimensional seismic-vibration dual-control shock-isolation support. Background technique [0002] At present, the seismic isolation bearings used in construction engineering are mainly used to reduce the horizontal seismic action of the superstructure, but the effect of this type of seismic isolation bearing on reducing the vertical seismic action or vertical vibration of the superstructure is not obvious. With the expansion of urban scale, most cities in China are currently developing underground rail transit, as well as underground and above-ground multi-functional comprehensive transportation hubs, in order to improve the transportation capacity within the city. Multi-functional comprehensive transportation hubs and underground rail transit are convenient and punctual an...
