Vertical seismic isolation support capable of bearing large horizontal force and layered seismic isolation pivot structure

Abstract

The invention discloses a vertical shock insulation support capable of bearing large horizontal force. The vertical shock insulation support comprises a horizontal stress component and a vertical shock insulation component. The horizontal stress main body mechanism comprises a first connecting part, a second connecting part, a third connecting part, a fourth connecting part, a first connecting rod and a second connecting rod, the upper seat plate and the lower seat plate are arranged in a spaced mode in the vertical direction, the vertical shock isolation component comprises an elastic piece, and the telescopic direction of the elastic piece is the vertical direction; the first end of the first connecting rod is rotationally connected with the first connecting part through a first hinge shaft; the second end of the first connecting rod is rotationally connected with the third connecting part through a second hinge shaft; the first end of the second connecting rod is rotationally connected with the second connecting part through a third hinge shaft, and the second end of the second connecting rod is rotationally connected with the fourth connecting part through a fourth hinge shaft. According to the scheme, large horizontal force can be well borne, and then the adverse effect of the large horizontal force on the vertical seismic isolation support is avoided. The invention further discloses a layered seismic isolation hub structure.

Description

technical field [0001] The invention relates to the technical field of vibration control and isolation in civil engineering and mechanical engineering, in particular to a vertical isolation support and a layered isolation hub structure that can withstand large horizontal forces, and is more suitable for large-span space structures composed of roofs. The large-span space hub structure composed of reinforced concrete structure, steel structure or composite structure and other substructures is also more suitable for seismic isolation in industrial, civil buildings, bridges, subway projects, mechanical equipment, instruments and other scenes. Background technique [0002] Affected by the circum-Pacific seismic belt and the Eurasian seismic belt, many countries and regions suffered severe earthquake disasters. Existing earthquake damage data show that earthquakes not only damage structural components, but also damage non-structural components. With the rapid development of the e...

AI Technical Summary

Problems solved by technology

Under the action of huge horizontal force, the existing vertical shock-isolation bearings are difficult to ensure the stability and safety of vertical movement when performing the shock-isolation function

That is, the existing vertical seismic isolation bearings cannot withstand huge horizontal forces well, resulting in the inability to achieve the expected seismic isolation effect when subjected to huge horizontal forces
