Flange extension type column foot for a narrow flange steel column and construction technology of column foot
The invention relates to a flange extension type column foot for a narrow flange steel column, and a construction technology of the column foot. The column foot is characterized in that the column foot is embedded into a reinforced concrete foundation; the column foot comprises a bottom plate arranged at the bottom end face of the steel column, and flange extension plates arranged on two side walls of two flanges of the steel column respectively; the flange extension plates are welded on the side walls of the flanges by groove complete-penetration welds, and welded with the bottom plate; vertical stiffening ribs are welded between the two opposite flange extension plates; horizontal stiffening ribs are arranged at a top port of a containing cavity; a plurality of studs are uniformly on the bottoms of outer wall surfaces of the two flanges respectively; and anchor bolts are arranged at the two ends of the bottom plate. According to the column foot, with the adoption of the horizontal stiffening ribs and the vertical stiffening ribs, the effective bearing width of an embedded part of the steel column is increased, a bending moment and a shearing force borne by an imbedded column foot node can be transferred conveniently, the embedded depth of the steel column can be reduced significantly, and the embedded depth of the foundation or a bearing platform can be further reduced. The column foot has better economic benefits in engineering practices.
