Problems solved by technology

However, when an earthquake occurs, in addition to the horizontal shearing action, sometimes there will be a large vertical lift-off effect on the seismic isolator, which often causes the seismic isolator to be damaged due to cracking or impact

Embodiment 1

[0013] Referring to Fig. 1, this embodiment is composed of an upper cover plate 1, a sleeve 2 and a cylindrical block 3, the bottom of the upper cover plate 1 and the top of the sleeve 2 are combined into one, and the sleeve 2 is set on the cylindrical block 3, between the two For sliding fit, eight one-to-one corresponding blind holes 4 are provided between the upper cover plate 1 and the cylindrical block 3, and elastic elements 5 are arranged in the blind holes 4. The elastic elements 5 are wire springs. The upper cover plate 1 and the sleeve 2 are formed separately.

Embodiment 2

[0015] Referring to Fig. 2, this embodiment is composed of an upper cover plate 1, a sleeve 2 and a cylindrical block 3, the bottom of the upper cover plate 1 and the top of the sleeve 2 are connected into one body, and the sleeve 2 is set on the cylindrical block 3, between the two For sliding fit, six blind holes 4 corresponding to each other are provided between the upper cover plate 1 and the cylindrical block 3, and elastic elements 5 are arranged in the blind holes 4 for energy dissipation. Six holes 6 are longitudinally arranged between the upper cover plate 1 and the cylindrical block 3, and guide pins 7 are arranged inside, and the pins 7 and the holes 6 are slidingly fitted.

[0016] The working principle of the present invention is: the upper cover plate of the shock isolator is connected with the cylindrical block 2 of the present invention, and the lower base plate of the shock isolator is connected with the foundation of the building or the building superstructure...

Embodiment 3

[0018] Fig. 3 is a schematic cross-sectional view of an embodiment of a combination of an anti-lift-off device for a seismic isolator and a rubber shock isolator. The structure of the anti-lift-off device for the seismic isolator of the present invention is the same as that of Embodiment 2. The anti-lift-off principles of other types of shock isolators such as skateboard, rolling ball, and track-type shock isolators are exactly the same, and they are not listed here.

Abstract

The lifting preventing device for earthquake isolator consists of upper cover plate, sleeve and cylinder. The upper cover plate has its bottom connected to the top of the sleeve, and the sleeve is around the cylinder in sliding fitting. There are several blind hole pairs in the upper cover plate and the cylinder separately and elastic elements set inside the blind holes. Between the upper cover plate and the cylinder, there are several longitudinal holes and guide pins inside the longitudinal holes in slide fitting. The present invention is matched with the damping and energy dissipating device to protect building against the lifting effect of earthquake, and is suitable for various kinds of earthquake isolators.

Description

technical field [0001] The invention relates to an anti-lift-off device, in particular to an anti-lift-off device for an earthquake shock isolator. Background technique [0002] Earthquakes cause great damage to buildings, and seismic isolators are an effective earthquake-absorbing and isolation facility. Usually, when an earthquake occurs, the isolator is subjected to seismic waves in three directions and six degrees of freedom. The effect of isolating and dissipating seismic waves through the isolation and energy dissipation of the shock isolator is achieved to protect the building from damage. However, when an earthquake occurs, in addition to the horizontal shearing action, sometimes there will be a large vertical lift-off effect on the seismic isolator, which often causes the seismic isolator to be damaged due to cracking or impact. Contents of the invention [0003] The present invention is realized by the following scheme: it is composed of an upper cover plate, a...
