Problems solved by technology

[0004] The purpose of the present invention is to provide a shape memory alloy three-dimensional composite shock-isolation bearing to solve the three-dimensional shock-isolation problem of the urban elevated subway station bridge structure system. The vertical shock-isolation effect can be realized through a rigid shell, a combined disc spring and a guide cylinder. The laminated rubber can achieve horizontal shock isolation, and the arrangement of SMA strands can maximize the multi-dimensional shock isolation, thus achieving the purpose of three-dimensional shock isolation

Abstract

A shape memory alloy three-dimensional composite shock insulation support relates to the technical field of shock insulation, and comprises a vertical shock insulation system, a connecting plate I, a horizontal shock insulation system and a connecting plate II, the vertical shock insulation system comprises a rigid shell, a combined belleville spring and a guide cylinder, the connecting plate I comprises a circular mounting hole I, a fixing ring and a high-strength bolt, and the connecting plate II comprises a circular mounting hole II, a fixing ring and a high-strength bolt. The horizontal shock insulation system comprises a protection plate I, laminated rubber, a protection plate II, a rubber protection sleeve and an SMA stranded wire; and a connection plate II comprises a circular positioning hole, a circular mounting hole II and a high-strength bolt. The three-dimensional shock isolation effect is achieved by arranging the horizontal shock isolation system and the vertical shock isolation system, the vertical shock isolation effect of the support is achieved through the rigid shell, the combined belleville spring and the guide cylinder, the combined belleville spring can provide enough bearing force and suitable vertical shock isolation rigidity, and the combined belleville spring is an ideal vertical shock isolation element; the laminated rubber and the SMA stranded wires achieve the horizontal shock insulation effect of the support, and the SMA stranded wires exert the three-dimensional energy dissipation capacity to the maximum extent. The three-dimensional composite shock insulation support can be applied to elevated subway station bridge structures and buildings with three-dimensional shock insulation requirements, and the application range is wide.

Description

technical field [0001] The invention belongs to the technical field of shock isolation, and in particular relates to a shape memory alloy three-dimensional composite shock isolation support. Background technique [0002] In the field of seismic isolation technology, the research and development of seismic isolation technology is relatively mature, and has received close attention from scholars and engineers in recent years. At present, most of the seismic isolation bearings can realize the function of horizontal seismic isolation, and the effect of vertical seismic isolation can hardly be realized, but the vertical seismic action will also cause serious disasters to buildings. On the one hand, ground motion is a complex three-way According to the existing Tangshan earthquake, Wenchuan earthquake and other earthquake time-history records and seismic damage data obtained from (extra) major earthquakes at home and abroad in recent years, it can be known that in high-intensity a...
