The invention discloses a hinged-supported steel frame node containing a full-length constrained solderless buckling-proof energy dissipation assembly, which comprises a frame column, an energy dissipation assembly, a frame beam, a third constraint plate and a fourth constraint plate. the energy dissipation assembly comprises a side plate, a first core plate and a second core plate; the side plateis detachably fixed on the frame column, and the first core plate and the second core plate are sequentially provided with a column side end plate, an energy consumption section and a beam side end plate in the length direction; the first core plate and the second core plate are horizontally and oppositely arranged at intervals from top to bottom, and the column side end plate is fixed on the side plate; the frame beam includes first and second restraint plates; the first restraint plate and the third restraint plate are respectively overlapped on the upper side and the lower side of the first core plate at intervals and are detachably fixed so as to restrain the first core plate in full length; the second restraint plate and a fourth restraint plate are overlapped on the upper side and the lower side of the second core plate at intervals and are detachably fixed so as to restrain the second core plate in full length; the first, second, third and fourth restraint plates are respectively provided with saw tooth butt joint slits in the front and rear directions. The node has strong anti-seismic capability and is fast to repair after earthquake.
