Abstract: A prefabricated steel-wood composite joint includes square pipe columns, steel-wood composite beams, and a beam-column connecting assembly for connecting the square pipe columns and the steel-wood composite beams. Each square pipe column includes connecting corner columns and connecting side plates. Each steel-wood composite beam includes a top flange, a bottom flange and wood webs for connecting the top flange and the bottom flange. The beam-column connecting assembly is a central column connecting assembly or a corner column connecting assembly. By a special structural design, the composite joint realizes effective beam-column connection without a welded connection and a bolted connection and has tenacity and good seismic performance. The components of the composite joint can be prefabricated in a factory, are high in precision and are assembled on site, so that construction is easy and convenient, procedures are simplified, and the construction period is effectively shortened.
