Embodiment 1

[0041] A kind of vertical vibration isolation device 3, such as figure 1 As shown, it includes a ring spring and a guide sleeve, and the ring spring is arranged in the guide sleeve; the ring spring includes a first group of ring springs 7 and a second group of ring springs 8, and the outer diameter of the second group of ring springs 8 is smaller than that of the first group of ring springs. The inner diameter of the spring 7, the first group of ring springs 7, the second group of ring springs 8 are arranged coaxially with the guide sleeve.

[0042] The vertical vibration isolation device 3 of the present invention adopts ring springs. The first group of ring springs 7 and the second group of ring springs 8 are formed by alternately stacking a plurality of inner rings 18 and outer rings 20 up and down. The inner rings 18 are inner cylindrical surfaces. The washer-shaped spring steel on the outer conical surface, the outer ring 20 is the washer-shaped spring steel on the inner ...

Embodiment 2

[0052] A vertical seismic isolation device, which is combined with a horizontal seismic isolation device to form a three-dimensional seismic isolation device, such as figure 2 As shown, it includes a horizontal vibration isolation device 1 and a vertical vibration isolation device 3, and the horizontal vibration isolation device 1 and the vertical vibration isolation device 3 are combined in series; the device of the present invention combines the horizontal vibration isolation device 1 and the vertical vibration isolation device 3 in series , which can not only isolate the horizontal earthquake action, but also effectively isolate the vertical earthquake action to meet the engineering needs.

[0053] The horizontal vibration isolation device 1 comprises a laminated rubber bearing 2 laminated rubber bearing 2; the laminated rubber bearing 2 comprises an upper fixing plate 201, a rubber block 202 and a lower fixing plate 203; the rubber block 202 is composed of one layer of rub...

Embodiment 3

[0057] Embodiment 3 provides a three-dimensional seismic isolation device. The structure of the three-dimensional seismic isolation device in this embodiment is basically the same as that of the three-dimensional seismic isolation device in Embodiment 2. The difference is that the horizontal seismic isolation device 1 in this embodiment is also Including buffer spring 10.

[0058] like image 3 As shown, the buffer spring 10 is evenly arranged around the rubber block 202 ; one end of the buffer spring 10 is fixed on the upper fixing plate 201 , and the other end is fixed on the lower fixing plate 203 . The diameter of the circle formed by the plurality of buffer springs 10 on the upper fixing plate 201 is smaller than the diameter of the circle formed on the lower fixing plate 203 . The buffer spring 10 is used to reduce the horizontal displacement of the laminated rubber bearing 2. When the laminated rubber bearing 2 moves to one side, the spring on the other side will gener...

Abstract

The invention relates to a vertical shock isolation device, and belongs to the technical field of shock isolation / vibration reduction. The vertical shock isolation device comprises an annular spring and a guide sleeve, and the annular spring is arranged in the guide sleeve; and the annular springs comprise a first group of annular springs and a second group of annular springs, the outer diameter of the second group of annular springs is smaller than the inner diameter of the first group of annular springs, and the first group of annular springs, the second group of annular springs and the guide sleeve are coaxially arranged. The first group of annular springs and the second group of annular springs are formed by alternately overlapping a plurality of inner rings and outer rings up and down, the inner rings are gasket-shaped spring steel with inner cylindrical surfaces and outer conical surfaces, and the outer rings are gasket-shaped spring steel with inner conical surfaces and outer cylindrical surfaces. The vertical shock isolation device can effectively isolate the vertical earthquake or vibration effect, and the engineering requirements are met.

Description

technical field [0001] The invention belongs to the technical field of vibration isolation / vibration reduction, in particular to a vertical vibration isolation device. Background technique [0002] Seismic isolation / vibration reduction technology is one of the most effective measures to mitigate seismic hazards or vibrations of structures. Various types of seismic isolation bearings currently used in building structures can effectively isolate horizontal earthquakes, but cannot isolate vertical earthquakes. The national standard GB50011-201 of the People's Republic of China "Code for Seismic Design of Buildings" clearly states that "during the seismic isolation design, the seismic isolation pad not only does not isolate the vertical seismic action but amplifies it, it is related to the horizontal seismic action of the isolated structure. Compared with the vertical seismic action, it is often not negligible.” [0003] In order to solve the problem that the existing seismic ...
