[0002] Steel-concrete columns are composite structural columns composed of thin-walled steel pipes and concrete fillers. This structure combines the advantages of steel and concrete, namely the high strength and toughness of steel and the good compressive strength and fire resistance of concrete. Usually, after the steel and steel bars are built, the formwork is built according to the shape of the column, and after the concrete is poured, it forms a corresponding concrete column with the steel and steel bars.

[0003] A prefabricated steel-concrete column disclosed in the existing patent announcement number CN218881182U includes a concrete layer, a beam, a fitting block and a protrusion. An "I"-shaped concrete layer is arranged at the bottom of the steel-concrete column body, and fitting blocks for plugging and cooperating with the beam are arranged on symmetrical sides of the upper part of the steel-concrete column body. The sides of the steel-concrete column body provided with the fitting blocks are provided with symmetrical grooves centered on the fitting blocks. One end of the beam is symmetrically provided with protrusions that can be inserted into the grooves. The beam is movably connected to the steel-concrete column body by inserting the protrusions into the grooves; the vertical connection between the beam and the steel-concrete column body is achieved by inserting the protrusions into the grooves and inserting the end of the beam into the fitting blocks. This connection method has the advantages of convenient construction operation and stable connection.
