Background
With the development of social economy, the steel pipe concrete column is increasingly used in the design of super high-rise building structures due to the advantages of large bearing capacity, small sectional area, safety and economy. The steel pipe concrete column needs to pass through an underground concrete structure and be anchored to an underground foundation end or a structure embedding end. Due to the diversity of basement beam-column joints and the particularity of steel structure processing, underground part connecting joints of concrete beams and steel pipe concrete columns are particularly complex, and main construction difficulties are concentrated on three aspects of beam-column longitudinal rib connection, column stirrup binding and concrete pouring compactness guarantee. The existing engineering method needs to reserve a reinforcing steel bar hole in a steel structure during factory processing, and on site, because the reinforcing steel bar is difficult to perforate, the method that the reinforcing steel bar bypasses a steel corbel is adopted, so that the structural structure and the stress are not facilitated.

Detailed Description
The present invention will be described in further detail by way of examples with reference to the accompanying drawings, which are illustrative of the present invention and are not intended to limit the present invention.
The embodiment of the utility model provides a concrete beam 3 and steel corbel including steel core concrete column 1, basement.
The steel pipe concrete column 1 is partially covered with a concrete layer 2 outside the basement. The concrete beam 3 of the basement is connected with the concrete-filled steel tubular column 1 through a steel corbel. The steel bracket comprises a steel flange 4 and a steel web 5, and the steel flange 4 is connected with the steel web 5 in a welding mode.
5 vertical settings of steel web, its welded fastening is on steel pipe of concrete filled steel tubular column 1, and steel web 5 is located between steel pipe and the post stirrup 6 of concrete filled steel tubular column 1, so 5 internal contracting of steel web, avoid the post stirrup of beam column node core area, and steel web 5 does not occupy post stirrup 6 position, and steel construction factory processing need not perforate in advance.
The steel flange 4 is horizontally arranged and is welded and fixed on the steel pipe of the steel pipe concrete column 1. The steel flange 4 is the polylith, sets gradually from top to bottom, and the 7 position determination of muscle are indulged to 4 positions combination beam on steel flange, and the 7 number of piles of muscle are indulged to 4 quantity combination beam on steel flange are confirmed to make one deck roof beam indulge muscle 7 and can be connected with a steel flange 4. And the beam longitudinal bars 7 of the concrete beam 3 are welded and fixed with the steel flange 4 by lap welding.
The bottom reinforcing steel bars 8 of the second row from bottom to top of the concrete beam 3 are cut off outside the beam-column node and do not extend into the beam-column node, so that the compactness of concrete pouring in a beam-column node area is ensured, and the construction difficulty is reduced.
