The invention relates to a fabricated steel-wood composite joint. The fabricated steel-wood composite joint comprises a square pipe column, a steel-wood composite beam and a beam-column connecting assembly connecting the square pipe column with the steel-wood composite beam; the square pipe column comprises a connecting corner column and a connecting side plate, the steel-wood composite beam comprises an upper flange, a lower flange and a wood web plate connecting the upper flange with the lower flange, and the beam-column connecting assembly comprises a central column connecting assembly anda corner column connecting assembly. Through special structural design, under the premise of welding and bolting connection, the beam and the column are effectively connected, certain toughness and good seismic performance are achieved, components of the fabricated steel-wood composite joint can be prefabricated in a factory, the component precision is high, on-site splicing is achieved, construction is easy and convenient, the processes are reduced, and the construction cycle is effectively shortened; and by adopting a steel-wood composite structure, the utilization rate of materials of different strength is increased, through ingenious connection and cooperation, the efficient and reasonable structure new form is achieved through combination and synergy of the steel-wood structure, and the rich diversity of architectural performance is improved.
