Abstract

The invention relates to a vertical vibration isolation device, which comprises an upper connecting plate, a lower connecting plate, an upper fixed support, a lower fixed support, an upper sliding support, a lower sliding support, a first rigid rod, a second rigid rod, Spring, friction plate; the upper fixed support is fixed on the upper connecting plate, the upper sliding support is connected with the friction plate, and is embedded in the chute of the upper connecting plate together, the lower fixed support is fixed on the lower connecting plate, and the lower sliding The support is connected with the friction plate and is embedded in the chute of the lower connecting plate. The two ends of the first rigid rod are respectively hinged in the upper fixed support and the lower sliding support, and the two ends of the second rigid rod are respectively hinged in the lower fixed support. In the support and the upper sliding support, the connecting part between the first rigid rod and the second rigid rod is hinged; one end of the spring is fixed and the other end is connected to the lower sliding support. The device has simple structure and low cost, and is used for vibration control of bridge engineering and building structures in areas with relatively large vertical seismic action.

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...
