Assembly type steel structure beam column joint structure

The utility model discloses an assembly type steel structure beam column joint structure which comprises a connecting column, four sets of assembly frames are arranged on the periphery of the connecting column, four sets of steel beams are connected to the peripheries of the assembly frames in a joggling mode, a plurality of transverse screws are connected to the two sides of the assembly frames in a threaded mode, the connecting column is provided with two sets of positioning blocks, and the positioning blocks are connected with a supporting frame. The edge of the supporting frame is in threaded connection with a positioning screw, and the supporting frame is in threaded connection with a longitudinal screw. According to the assembly type steel structure beam-column joint structure, if a falling object generated during construction attacks towards the inclined face of the supporting frame, the falling object makes contact with the protection plate firstly, under the action of the impact force of the falling
