and a sixth step: a shear key is welded below the bottom plate;
the seventh step: the steel frame column and the peripheral concrete column are cast into a whole by fine stone concrete.
The invention has the beneficial effects that:
compared with the prior art, the method for connecting the steel frame column and the concrete column base and manufacturing the steel frame column and the concrete column base has the advantages that the shear key made of H-shaped steel can meet the requirement on the lower portion of the bottom plate, one part of the pressure of the column is transmitted to the bottom plate through the connecting welding seam between the column body and the bottom plate and then transmitted to the peripheral concrete foundation, the other part of the pressure of the column is transmitted to the belly stiffening rib steel plate and the flange stiffening rib steel plate and then transmitted to the peripheral concrete foundation through the column body, and the non-shrinkage fine stone concrete is poured between the steel frame column and the peripheral concrete foundation to form a whole. In the steel reinforced concrete column base, a welded steel frame column is mainly configured, and a longitudinal steel bar and a stirrup are also configured, so that the steel reinforced concrete column base has better anti-seismic performance, the steel reinforced concrete column base restrains the deformation of the concrete column base, and the bearing capacity is improved. The steel reinforced concrete column base not only has high bearing capacity, but also has good ductility and toughness. Meanwhile, the longitudinal ribs can be prevented from yielding too early, so that the longitudinal ribs can better cooperate with the profile steel until the rod piece is damaged, and the longitudinal ribs are effectively utilized.
