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.
