Profile steel beam reinforcing structure and construction method

The invention relates to the technical field of building construction, in particular to a profile steel beam reinforcing structure and a construction method.The profile steel beam reinforcing structure comprises a beam column, symmetrical mounting grooves are formed in the outer walls of the two sides of the beam column, and positioning grooves are formed in the outer walls of the sides, adjacent to the mounting grooves, of the beam column; the connecting structure has the beneficial effects that firstly, the mounting columns, close to the outside, on the inner side of the first connecting frame are aligned with the mounting grooves and then are inserted in a sliding mode, then insertion is completed through the mounting columns on the rear side, the inserting plates on the second connecting frame are inserted into the inner walls of the inserting grooves, and then the connected connectors are welded and fixed; one end of the profile steel is inserted into the inner wall of the fixing frame, the protruding be
