Description
Technical Field
The invention belongs to the technical field of building shock insulation supports, and particularly relates to a sliding plate support.
Background
The seismic isolation layer is arranged between the upper structure and the lower structure of the engineering structure to block the transmission of seismic energy, and the seismic isolation layer is a mature technology for reducing the seismic reaction of the engineering structure and lightening the seismic damage. The laminated rubber bearing seismic isolation technology is widely applied to various houses and bridges.
In a building structure, due to different internal forces at the column bottom, shock insulation rubber supports in shock insulation layers need to be selected according to different bearing capacity requirements so as to meet the requirements of building structures and shock insulation. The national standard 'building earthquake-resistant design specification' makes a clear regulation on the limit value of the horizontal displacement of the earthquake-resistant rubber support under the action of rare earthquakes. Because the limit value of the limit horizontal displacement of the shock insulation rubber support with the minimum specification in the shock insulation layer limits the horizontal displacement of the shock insulation layer, the shock insulation effect is influenced. Moreover, the existing shock insulation rubber support has the defect of relatively poor shock insulation effect in small shocks.
In order to solve the defect of the shock insulation rubber support, a combined shock insulation technology consisting of the shock insulation rubber support, a sliding plate support and a viscous damper is applied, and the application is more and more extensive. Although the sliding plate support solves some defects of the shock insulation rubber support, the plane size of the sliding plate support is greatly increased relatively, and new problems are brought to the design and the use of the structure.
