Technical scheme of the present invention is a kind of beam column node connection device of assembling type steel structure system, and described linkage comprises end flanges, node short column and node short column upper flanges under column base junction plate, solid web girder, clamping plate, upper prop flange, lower prop flange, node short column; Under described node short column upper flanges and node short column, end flanges is welded in the upper/lower terminal of node short column respectively; Described column base junction plate is welded in node short column lateral surface, and column base junction plate upper and lower end is integral with node short column upper flanges, node short column lower end flange welding respectively; Described upper prop flange, lower prop flange are welded as a whole respectively at upper lower prop; Described node short column upper flanges is connected by bolt a with upper prop flange, and under described node short column, end flanges is connected by bolt a with lower prop flange; Described two clamping plate are connected with column base junction plate and solid web girder web by bolt; Described upper prop flange, lower prop flange are connected by bolt b with the upper bottom flange of solid web girder respectively;
The cross section vertical axis of described column base junction plate is alignd with the vertical axis of node short column side and the vertical cross-section vertical axis of solid web girder.
Under described column base junction plate and node short column and node short column upper flanges, node short column, end flanges is integrally welded in factory; Described upper prop flange and upper prop integrally welded in factory; Described lower prop flange and lower prop integrally welded in factory.
Described column base junction plate is connected by clamping plate and two row's bolt c with the described solid web girder edge of a wing.
Described node stub cross-sections is square; Under described node short column upper flanges and node short column, end flanges is square.
Described column base junction plate welds with the side of described node short column.
Described upper prop flange and described lower prop flange are connected with two, three of end flanges under described short column upper flanges and node short column or four edges respectively.
The beam column node connection device of assembling type steel structure system of the present invention, section components can weld in factory, and assembled the needs bolt at later stage scene there is no on-the-spot welding job requirements, and the layout of bolt is also easy to operative, substantially increases assembling speed and quality.
Bean column node of the present invention is that on-the-spot bolt connects, and belong to rigid joint, simultaneously due to rational bolt arrangement, when geological process, can realize plastic hinge, the beam-ends outside node forms plastic hinge, effectively protects node, realizes the weak component of strong node.
