Example Embodiment

[0038] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0039] like figure 1 As shown, a sliding shock-isolation bearing 1 of the present invention includes upper and lower bearings, the upper bearing 11 is supported by the lower bearing 12; an interlayer pad 6 is provided between them, including The upper layer interlayer pad on the support 11 that is integrally linked with it, and the lower layer interlayer pad fixed on the lower support 12 that is integrally linked with it (not shown in the figure for the sake of simplicity); the material of the interlayer pad 6 is made of weak Magnetic permeability and high electrical conductivity materials, specifically, materials with relative magnetic permeability less than 1 and relative electrical conductivity greater than 50 are used; preferably, aluminum plates are used; the outer surfaces of the upper interlayer pad and the lower interlayer pad are respe...

Abstract

The invention discloses a slip vibration isolation support which comprises an upper support and a lower support. The upper support is supported by the lower support, and interlayer surfaces are arranged between the upper support and the lower support; the upper support and the lower support are both filled with lead core rubber and internally provided with annular permanent magnets in a staggered mode, and the upper permanent magnet and the lower permanent magnet are both arranged to be close to the interlayer surfaces so as to provide sufficient magnetic induction intensity; the vibration support adopts aluminum plates as the interlyaer surfaces, outer sealing is conducted through annular steel tanks, and the interlayer surfaces are covered with polytetrafluoroethylene plates. Compared with a traditional vibration isolation support, the internally arranged magnet type vibration isolation support has the advantages of being small in abrasion, high in sensitivity, good in filtering property, high in energy consumption, small in impact effect, high in self reset capacity, capable of saving space, good in tensile property and the like, and important significance in solving the technical problems that deformation of the vibration isolation support of the area with high seismic intensity is too large, the impact effect is significant, and the tensile property is weak is achieved.

Description

technical field [0001] The invention belongs to the technical field of engineering and relates to a built-in magnet type sliding shock-isolation support. Background technique [0002] Seismic isolation technology is a kind of structural shock absorption control technology that has been researched and applied maturely. Its basic principle is to install some kind of seismic isolation and energy dissipation device between the upper structure and the lower support or foundation, and move it away from the excellent cycle of the structural system. The excellent cycle of ground motion achieves the purpose of reducing the vibration of the upper structure. Due to its low construction cost, high reliability, simple principle, easy implementation, and good shock isolation effect, it is suitable for structural shock absorption, especially for important buildings and bridges in high-intensity areas. It is the most widely used technology for engineering structure shock absorption control ...
