Abstract

The invention provides a building structural foundation with three-dimensional shock insulation and vibration attenuation. The building structural foundation with three-dimensional shock insulation and vibration attenuation mainly comprises a steel structural small platform laid the roots in a foundation, a shock absorber mounting sliding table and an elastic damping shock absorber, wherein a polytetrafluoroethylene based coating is prepared on the steel structural small platform; a self-lubricating composite material containing oil is adopted in the shock absorber mounting sliding table to beused as a sliding friction pair; according to the elastic damping shock absorber, disc spring support is adopted on the lower surface of a main piston, a liquid damping medium below a floating pistonhas low internal pressure in a static state, and the shock absorber works stably for a long time and no oil leakage occurs; an upper mounting joint and a lower mounting joint of the shock absorber have a slight cardan joint adjusting function; when an earthquake happens, the steel structural small platform vibrates with small amplitude following the foundation under the influence of earthquake waves, the mounting sliding table, the shock absorber on the upper part of the mounting sliding table and a building slide relatively on the steel structural small platform, so that earthquake energy inthe horizontal direction is weakened and input to the building on the upper surface; and the shock absorber has damping and energy absorption functions in the vertical direction, and thus, three dimensions have shock insulation and vibration attenuation protection action.

Description

technical field

[0001] The invention belongs to the technical field of building foundation shock isolation, energy dissipation and vibration reduction. technical background

[0002] Base isolation refers to the isolation layer which is composed of rubber bearings, damping devices and other components and has an overall reset function set between the foundation, bottom or substructure and superstructure of buildings such as houses. The time-lag effect of deformation can prolong the natural vibration period of the entire structural system, reduce the horizontal seismic action input to the upper structure, and meet the expected seismic requirements; the design of energy dissipation and shock absorption refers to the installation of energy absorbers in the building structure, and through the energy absorbers The relative deformation and relative velocity provide additional damping to dissipate the seismic energy input into the structure and meet the expected shock absorption req...
