A beam-column steel structure node for a prefabricated concrete green energy-saving house unit according to claim 6, characterized in that: The cylindrical fixing cylinder is provided with through holes in different directions, and the arc-shaped fixing block can be welded when cooperating with the cylindrical fixing cylinder, and the cover plate is matched with the side wall fixing plate 1 and the side wall fixing plate 2 by bolts, the length of the adjustable fixing support plate is greater than the length of the adjustable fixing support plate, and the length of the adjustable fixing support plate is greater than the length of the side wall fixing plate 1 and the side wall fixing plate 2, the two adjacent adjustable fixing support plates and the adjustable fixing support plate 2 can be constructed in sections, and the two do not interfere with each other, and elastic buffer pads are provided on the inner walls of the side wall fixing plate 1 and the side wall fixing plate 2, the length of the cross beam is the length of the ends of the two oppositely arranged side wall fixing plates 1 and the side wall fixing plates 2, and a knot cover is provided on the end of the cross beam, and the knot cover is an L-shaped structure, and the arc-shaped fixing block, the side wall fixing plate 1, the side wall fixing plate 2 and the bottom plate are integrally formed.

8. A beam-column steel structure node for a prefabricated concrete green energy-saving house unit according to claim 7, characterized in that: The construction steps of the beam-column steel structure node are: S11. First, according to the actual needs of the construction site, connect the vertical support steel 1, vertical support steel 2, vertical support steel 3 and vertical support steel 4 to the node connection member, and fix the vertical support steel at the bottom; S12, during construction, the jacking components can be coordinated for adjustment and placement, and multiple jacking components can be coordinated for adjustment during adjustment, and the adjustable fixed support plate and the second adjustable fixed plate can be adjusted according to actual needs. At the same time, the beams to be spliced ​​are placed on the opposite adjustable fixed support plate and the second adjustable fixed plate through the hoisting device, and the middle part is jacked up by controlling the jacking components; S13. At the same time, during the construction process, due to the knot cover, one end of the beam can be first inserted between the side wall fixing plate 1 and the side wall fixing plate 2, and then under the action of the lifting component, the other end of the beam can be inserted, thereby avoiding the end being difficult to place due to local deviations and protrusions generated during the prefabrication process.
