Three-dimensional friction pendulum shock insulation support with tensile function

Abstract

The invention discloses a three-dimensional friction pendulum shock insulation support with a tensile function, and relates to the technical field of friction pendulum shock insulation supports, the three-dimensional friction pendulum shock insulation support comprises an upper support plate, an upper sliding part, a vertical shock insulation unit, a lower sliding part and a lower support plate, the upper sliding part is arranged at the lower end of the upper support plate, the vertical shock insulation unit is arranged at the lower end of the upper sliding part, and the vertical shock insulation unit is arranged at the lower end of the lower sliding part. A lower sliding part is arranged at the lower end of the vertical seismic isolation unit, a lower support plate is arranged at the lower end of the lower sliding part, and the upper support plate directly faces the lower support plate; a first mounting hole is formed in the first support body, a first gap is formed between an upward-protruding arc arranged on the inner wall of the upper side of the first groove and the first arc-shaped face, and an upper sliding part is arranged in the first gap in a sliding mode. The anti-drawing performance is ensured; mutual coupling of the horizontal mechanical property and the vertical mechanical property of the support is avoided; a torsion effect can be provided under the tension and compression conditions of the support; the support can horizontally isolate shock and can also vertically isolate shock, namely, the support can achieve three-dimensional shock isolation.

Description

technical field [0001] The invention relates to the technical field of a friction pendulum shock-isolation support, in particular to a three-dimensional friction pendulum shock-isolation support with a tensile function. Background technique [0002] The frequent occurrence of earthquakes will cause damage to building structures, resulting in casualties and economic losses. In order to improve the ability of building structures to resist external load damage such as earthquakes, it is a simple, economical and effective measure to install seismic isolation bearings in the structure. The building structure with seismic isolation design mainly adopts laminated rubber isolation bearing system, friction pendulum isolation bearing system and friction slip isolation bearing system between the building foundation, bottom or substructure and superstructure. , mild steel damping bearing system, etc., to prolong the natural vibration period of the entire structural system, reduce the h...

Problems solved by technology

[0003] When an earthquake strikes, the traditional friction pendulum support can meet the needs of superstructure rotation and horizontal displacement, but it does not have the ability to resist vertical pullout, especially when it is subjected to a large vertical earthquake force. Each component may fail to disengage, causing serious consequences
