The utility model discloses an embedded column foot of a high-rise steel structure building, which comprises an upper column foot bottom plate and a lower column foot bottom plate which are arranged in parallel, and studs are fixed on a box-shaped column between the upper column foot bottom plate and the lower column foot bottom plate in a welding manner to form an inverted-frustum-shaped integralembedded column foot; during use, the box-type column is arranged below a top plate of an elevation basement; the waterproof requirement of a basement is met. Concrete is wrapped above the top elevation of the foundation to form a steel-reinforced concrete column; the steel reinforced concrete column is provided with angle ribs, longitudinal ribs and stirrups. According to the embedded column base, reinforcing stirrups are arranged in a concrete foundation, the embedded column base is fixed in the concrete foundation through gaskets and embedded anchor bolts, and when the strength of the concrete foundation reaches the designed strength, the box-type column above the top elevation of the concrete foundation is fixed to a column base upper bottom plate of the embedded column base through groove welding. The manufacturing or mounting problem of an embedded column base of an existing high-rise steel structure building is solved.
