Problems solved by technology

When the rubber bearing is deformed in the direction of 45 degrees, or other x and y directions are deformed, the original measures to protect the rubber bearing and the limit will be greatly reduced, or completely lose their effect

Embodiment Construction

[0022] Such as Figure 1-6 As shown, a kind of circular non-contact rubber bearing protection mechanism of the present invention, its specific implementation is as follows:

[0023] Both the outer magnet 1 and the inner magnet 2 have four arc-shaped magnets to form a circle, the N pole of the outer magnet 1 faces inward, and the N pole of the inner magnet 2 faces outward (or the S pole of the outer magnet 1 faces inward, and the N pole of the inner magnet 2 The S pole is outward), and there is a certain reserved distance between the inner and outer magnets; the outer magnet 1 is connected to the lower connecting plate 4 through the first reaction support 3, and the lower connecting plate 4 is connected to the lower steel plate of the rubber bearing 6; The inner magnet 2 is connected to the upper connection plate 5 through the second reaction force support 3 ; the upper connection plate 5 is connected to the upper steel plate of the rubber support 6 . All connections are bolte...

Abstract

The invention relates to a round non-contact type protection mechanism for a rubber base, and belongs to the technical field of building structural shock absorption and isolation. The protection mechanism comprises an outer magnet, an inner magnet, a reacting force base, a lower connecting plate and an upper connecting plate. Both the outer magnet and the inner magnet are formed by four curved magnets to be ring-shaped. Magnetic poles of the outer magnet are opposite to the same magnetic poles of the inner magnet, and a distance is reserved between the outer magnet and the inner magnet. When the distance between the two magnets is shortened, a produced repulsive force between the two magnets can hinder the deformation of the rubber base and enable the deformation of the rubber base within a safe range.

Description

technical field [0001] The invention relates to a circular non-contact rubber bearing protection mechanism, which belongs to the technical field of shock absorption and isolation of engineering structures, and is mainly used for the protection of rubber bearings in earthquake-isolated buildings and bridges. Background technique [0002] The seismic isolation structure separates the upper and lower structures through laminated rubber bearings, and reduces the seismic response of the upper structure by reducing the stiffness of the isolation layer and increasing the displacement of the isolation layer. performance, its application is becoming more and more extensive. When investigating the earthquake-isolated buildings after the earthquake, it was found that the earthquake-isolation layer collided with the foundation. There may be two reasons for this phenomenon. One is that due to the irregularity of earthquake waves, the low-frequency Part of it resonates with the structure...
