1. A construction method for a prefabricated concrete beam-column node, comprising:
assembling node connectors, and mounting studs on each node connector, wherein the studs are evenly distributed along an extension direction of the node connectors;
welding a circumferential reinforcing plate with a groove hole in the center to a middle-rear section of each node connector;
mounting a longitudinal rebar on each circumferential reinforcing plate;
filling concrete between two circumferential reinforcing plates to form a middle section;
welding a hidden corbel to a side flange of each of structural columns;
hoisting the middle section, and overlapping each node connector with the corresponding hidden corbel;
welding each node connector to the corresponding structural column; and
filling concrete between the respective circumferential reinforcing plate and the corresponding structural column to form a connection section.
