Novel assembly type steel structure beam-column joint and construction method thereof

The invention discloses a novel assembly type steel structure beam-column joint and a construction method thereof in the technical field of building section steel beam-column joint connecting structures. The joint structure comprises a section steel column and a plurality of section steel beams vertically installed on the side wall of the section steel column, wherein the outer wall of the section steel column is sleeved with a steel sleeve in an attached mode, the connecting ends of the section steel beams are welded to the center area of the steel sleeve, cable-stayed connecting pieces are connected between side flanges on the two sides of the section steel column and upper flanges on the two sides of the section steel beam, a hole is formed in the lower side of the steel sleeve, and the steel sleeve and the section steel column are tightly connected through a first connecting steel plate, a high-strength bolt and a nut. According to the joint structure, the stability and integrity of the joint are guarante
