Description
Technical Field
[0001] The utility model relates to the technical field of earthquake-proof and anti-pullout technology, and more specifically, to an anti-pullout device for a building's earthquake-isolating layer. Background Art
[0002] In the construction industry, pullout resistance technology is widely used in various structural designs. For example, the design and construction of pullout pile foundations require consideration of the material's pullout resistance. Proper pullout resistance design can ensure the stability and safety of building structures under tensile loads.
[0003] However, when an earthquake strikes, the building will produce a certain horizontal displacement. If the anti-pullout device is fixedly installed, the device will be damaged due to the horizontal displacement, which is not enough to achieve the earthquake-proof effect in the vertical direction. In traditional devices, there will also be sliding anti-pullout devices. The structural support capacity of the device itself is weak and the installation is more difficult. Therefore, it is necessary to improve and optimize the anti-pullout device used in the seismic isolation layer. Utility Model Content
[0004] In order to overcome the deficiencies of the prior art, the utility model provides an anti-pullout device for a seismic isolation layer of a building, which has the advantages of simple structure, significant sliding effect, high structural strength and easy installation.

[0007] As an optimal technical solution of the present invention: the transverse movement structure includes a second slider fixedly connected to the upper surface of the connecting plate, a second sliding column is movably connected inside the second slider, and a second type of V-shaped plate is fixedly connected to the upper surface of the second sliding column.
[0008] As a preferred technical solution of the present invention: a second fixing groove is opened at the lower part of the second slider, the second slider is fixedly connected with a third hollow rivet at the second fixing groove, and the second slider is fixedly connected to the connecting plate through the third hollow rivet.
[0009] As an optimal technical solution of the present invention: a fourth hollow rivet is provided on the upper surface of the second type V-shaped plate, a fixing hole is fixedly connected inside the fourth hollow rivet, and the upper surface of the second type V-shaped plate is fixedly connected to the second embedded plate through the fixing hole.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0013] 1. This utility model connects the embedded plates of the upper and lower parts of the seismic isolation layer with an anti-pullout device at the middle connection. The middle anti-pullout device consists of a slider and a slide rail. This device can resist the vertical displacement of the building during an earthquake (the maximum vertical displacement does not exceed 30mm). At the same time, the slider and the slide rail cooperate to not affect the horizontal displacement caused by the earthquake (the maximum horizontal displacement is 450mm). When installing the anti-pullout device, sufficient horizontal displacement space must be reserved to ensure normal application. This device has the advantages of simple structure, significant sliding effect, high structural strength, and easy installation.
[0014] 2. This invention utilizes a first steel ball that rotates within the first slider and contacts the surface of the first slide column, creating a friction pair effect. This creates a friction coefficient and wear rate between the friction pairs. This not only helps reduce component wear but also extends the life of the mechanical system. Compared to traditional devices, where the friction in the pull-out structure is greater, hindering spatial displacement, this device extends its lifespan and is highly practical.
