Steel structure rapid installation joint structure

The invention discloses a steel structure rapid installation node structure which comprises a steel column and a cross beam, the side face of the steel column is fixedly connected with a cross beam connecting base, a matched groove is formed in the cross beam connecting base, and closure sections are arranged at the two ends of the cross beam and embedded in the matched groove; and a mounting positioning assembly and an auxiliary fixing assembly are arranged on the wedging groove. By arranging the cross beam connecting base, when the steel column and the cross beam are connected, the folding section on the cross beam is embedded into the matching groove in the cross beam connecting base, rough positioning of the steel column and the cross beam is completed, then auxiliary positioning is conducted through the installation positioning assembly, and fixing operation is conducted through the auxiliary fixing assembly; welding is replaced to a certain extent, operation is simplified, and efficiency is improved; th
