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.

Abstract: A cylindrical sleeve-type steel-wood composite joint includes fiberglass reinforced panel (FRP) cylindrical wood columns, X-shaped wood beams, a key connecting component, arc connecting pieces and splicing outer ring plates. The key connecting component consists of upper and lower cylindrical steel sleeve plates, a connecting sleeve, a cylindrical solid wood and filling wood blocks. The FRP cylindrical wood columns are connected to the key connecting component and are inserted into the key connecting component through the cylindrical steel sleeve plates and penetrative steel bars. The X-shaped wood beams are connected to the key connecting component through the arc connecting pieces, and the splicing outer ring plates are fixed with bolts to realize combination and connection. By adoption of the design of the connecting sleeve, the joint has a high bearing capacity, vertical force transfer is guaranteed, operation is easy, and assembly is fast.
