Elastic metal slider support

Abstract

The invention relates to an elastic metal slider support, which comprises a lower embedded plate, a base, an upper embedded plate, a top plate and an elastic metal layer. The lower embedded plate is disposed at the bottom, the base is fixed on the upper surface of the lower embedded plate through bolts, a stainless steel plate is welded on the base, the upper embedded plate is disposed at the top, the top plate is fixed on the lower surface of the upper embedded plate through bolts, the bottom of the top plate is provided with a recess, the elastic metal layer is inserted in the recess and disposed on the base, the elastic metal layer is composed of a metal spring pad and a polytetrafluoroethylene plastic layer, the stainless steel plate and the metal elastic layer form a friction pair, and accordingly the requirement that a superstructure of the elastic metal slider support slides relative to an understructure of the elastic metal slider support in case of an earthquake or big wind. Compared with the prior art, the elastic metal slider support has the advantages of high vertical bearing capacity, high temperature resistance, long-term stable performance and the like.

Description

technical field [0001] The invention relates to a support, in particular to a metal elastic sliding plate support. Background technique [0002] Seismic isolation technology is one of the most mature high-tech popularized and applied in the field of earthquake engineering in the world at present. It is truly possible to prevent collapse, making it one of the most effective means of mitigating earthquake disasters." [0003] Seismic isolation technology is to install a sufficiently safe seismic isolation system between the superstructure of the building and the foundation. Due to the "shock isolation" and "shock absorption" functions of the seismic isolation layer, the superstructure will move approximately in translation during an earthquake, and the structural response level is only equivalent to 1 / 4 to 1 / 8 of the earthquake without earthquake isolation, and 1 / 2 to 1 / 16 of the strong earthquake observation results, thus "isolated" the earthquake. In layman's terms: the hou...

AI Technical Summary

Problems solved by technology

[0005] 1) The vertical bearing capacity of the rubber elastic layer is limited, resulting in low vertical bearing capacity of the entire support;

[0006] 2) The rubber material cannot withstand high temperature, so strict treatment for fire prevention is required;

[0007] 3) The rubber aging problem is serious, the long-term performance is unstable, and the normal service life cannot be guaranteed
