the column cover plate (11) welded by the column is connected with the column base flange (7-3) and the beam with bolts; the column base flange (7-3) welded by the column and the column base method on the column base The flange (7-3) is connected with bolts; at the node where the inner side is not connected to the support, the upper and lower ends of the column (8) are welded with the column cover plate (11), and the column cover plate (11), the column base flange (7-3) 1. The connected beams are connected together with bolts; at the joints connected to the supports, the webs of the support connectors (16) are connected to the connected beams and column bases that are perpendicular to each other, and the two flanges are respectively connected to the perpendicular to each other. Beams and column bases are connected and all are welded; The column base (7) is a column pier with column base flanges on the upper and lower sides, surrounded by column base connectors (7-1) with bolt holes; all parts are connected together by welding; the column cover plate (11), column The seat flange (7-3) and the connected beam are connected together with bolts; the support connector (16) is connected with the connected beam and column seat (7) perpendicular to each other, and the two flanges are respectively connected to the The places where the mutually perpendicular beams and post bases (7) that are connected are connected are all welded.
