Abstract

The invention relates to a vertical seismic isolation apparatus. The vertical seismic isolation apparatus comprises an upper portion connecting board, a lower portion connecting board, an upper portion fixed support, a lower portion fixed support, an upper portion sliding support, a lower portion sliding support, a first rigid rod, a second rigid rod, a spring and friction boards. The upper portion fixed support is fixed to the upper portion connecting board; the upper portion sliding support is connected to the corresponding friction board; and the upper portion sliding support and the corresponding friction board are embedded in a sliding channel in the upper portion connecting board. The lower portion fixed support is fixed to the lower portion connecting board; the lower portion sliding support is connected to the corresponding friction board; and the lower portion sliding support and the corresponding friction board are embedded in a sliding channel in the lower portion connecting board. The two ends of the first rigid rod are respectively hinged in the upper portion fixed support and the lower portion sliding support. The two ends of the second rigid rod are respectively hinged in the lower portion fixed support and the upper portion sliding support. The middle portion of the first right rod is hinged to the middle portion of the second rigid rod. One end of the spring is fixed, and the other end of the spring is connected to the lower portion sliding support. The vertical seismic isolation apparatus is simple in structure and low in cost, and is used for vibration control for bridge engineering and building structures in areas having relatively large vertical seismic effects.

Description

technical field [0001] The invention relates to the technical fields of environmental vibration and shock resistance and shock absorption, in particular to a vertical shock isolation device, which is used for shock absorption / vibration in ordinary buildings, special structures, bridges, and mechanical equipment. Background technique [0002] Strong earthquakes are one of the serious natural disasters that threaten human beings. The seismic isolation structure system increases the structural damping by prolonging the natural vibration period of the superstructure, reduces the seismic response of the structure, and ensures that the superstructure can still be in an elastic state or remain in the initial state of elastoplastic deformation during a major earthquake. Seismic isolation technology not only ensures the safety of the structure itself, but also protects the internal equipment and facilities of the structure. However, in the design of horizontal seismic isolation, sch...
