Embodiment 1
[0020] see Figure 1-3 , a plug-in beam-to-column node connection device for a prefabricated structural system, including a chord frame, and the chord frame includes two parallel chords 1 and a sleeve 7 welded between the chords 1 and respectively The upper column 6 and the lower column 8 that are plugged and matched with the sleeve 7; the two parallel chords 1 are connected into a whole through the truss web 2, and the sleeve 7 is a cuboid with openings at both ends. The upper flange 5 of the sleeve and the lower flange 9 of the sleeve are respectively welded on the edge of the opening end, and the bottom of the upper column 6 is provided with an upper convex column 16 that is plugged and matched with the opening of the upper end of the sleeve 7. The upper part of the lower column 8 is provided with a lower convex column 15 which is plug-fitted with the opening of the lower end of the sleeve 7 .
[0021] Near the root of the upper boss 16 is welded an upper column flange 4 t...
Embodiment 2
[0029] According to the structure disclosed in Embodiment 1, the chord frame, the upper column 6 and the lower column 8 are pre-processed in the factory. When transported to the construction site in the later stage, only the butt joint assembly operation is required. There is no welding operation requirement on site, and the bolts The layout is also easy to operate manually, which greatly improves the assembly speed and quality.
