Embodiment 1

[0043] A three-dimensional shock-isolation bearing, such as figure 1As 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 vertical vibration isolation device 3 includes an annular spring and a guide sleeve, and the annular spring is arranged on In the guide sleeve; the ring springs include a first group of ring springs 7 and a second group of ring springs 8, the outer diameter of the second group of ring springs 8 is smaller than the inner diameter of the first group of ring springs 7, the first group of ring springs 7, the second group of ring springs The spring 8 is arranged coaxially with the guide sleeve.

[0044] The device of the present invention combines the horizontal seismic isolation device 1 and the vertical seismic isolation device 3 in series, which can not only isolate the horizontal seis...

Embodiment 2

[0058] Embodiment 2 provides a three-dimensional seismic isolation bearing. The structure of the three-dimensional seismic isolation bearing of this embodiment is basically the same as the structure of the three-dimensional seismic isolation bearing of Embodiment 1. The difference is that in this embodiment, the horizontal seismic isolation The device 1 also includes a buffer spring 10 .

[0059] Such as figure 2 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 o...

Embodiment 3

[0062] Embodiment 3 provides a three-dimensional seismic isolation bearing. The structure of the three-dimensional seismic isolation bearing of this embodiment is basically the same as the structure of the three-dimensional seismic isolation bearing of Embodiment 2. The difference is that the horizontal seismic isolation device 1 also includes bezel.

[0063] In this embodiment, the size of the upper fixing plate 201 is smaller than that of the lower fixing plate 203 , the bottom of the baffle is fixed on the lower fixing plate 203 by a torsion spring, and the top of the baffle abuts against the side of the upper fixing plate 201 . The distance from the bottom end of the baffle to the central axis of the laminated rubber bearing 2 is greater than the distance from the top of the baffle to the central axis, and the baffle provides certain horizontal support for the laminated rubber bearing 2 .

[0064] A plurality of baffles are provided, and the plurality of baffles are evenly...

Abstract

The invention relates to a three-dimensional shock-isolation support, which belongs to the field of shock-isolation technology and solves the problem of poor vertical shock-isolation performance stability of the shock-isolation support in the prior art. The three-dimensional vibration isolation support includes a horizontal vibration isolation device and a vertical vibration isolation device, and the horizontal vibration isolation device is combined in series with the vertical vibration isolation device; the vertical vibration isolation device includes an annular spring and a guide sleeve, The ring spring is arranged in the guide sleeve; the ring spring includes a first group of ring springs and a second group of ring springs, the outer diameter of the second group of ring springs is smaller than the inner diameter of the first group of ring springs, and the first group of ring springs has an inner diameter smaller than the first group of ring springs. One group of ring springs, the second group of ring springs are arranged coaxially with the guide sleeve. The device of the invention can not only isolate the horizontal earthquake action, but also can effectively isolate the vertical earthquake action, and the three-dimensional seismic isolation support meets the engineering requirements.

Description

technical field [0001] The invention belongs to the technical field of shock isolation, in particular to a three-dimensional shock isolation support. Background technique [0002] Seismic isolation technology is one of the most effective measures to reduce the damage of structures caused by earthquakes. 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 isolation products cannot isolate the...
