Connecting joint of superposed beam and concrete column and construction method of connecting joint

The invention provides a connecting joint of a superposed beam and a concrete column and a construction method of the connecting joint, and relates to the field of beam-column joints. The connecting joint of the superposed beam and the concrete column comprises the superposed beam and the concrete column, the superposed beam comprises a prefabricated beam body, a beam steel bar structure arrangedin the prefabricated beam body and a pre-buried structure, and the upper portion of the beam steel bar structure protrudes out of the upper side face of the prefabricated beam body; and the pre-buriedstructure is arranged in the length direction of the prefabricated beam body, one end of the pre-buried structure extends to the outer side of the end face of the prefabricated beam body in an overhanging mode, and the overhanging part of the pre-buried structure is provided with a supporting structure used for being matched with the top face of the concrete column. During construction, the superposed beam can be hoisted
