All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-2, the present invention provides a technical solution: a node structure of a compound steel pipe concrete column and a steel beam and a manufacturing method thereof are disclosed, the device comprises a compound steel pipe concrete column 1, an H-shaped steel beam 2, a flange plate 3, a flange bolt 10, a reinforcing ring plate 4, a prefabricated steel beam sleeve 5, a high-strength bolt 14, a brass friction plate 12, a pre-tightening bolt 9, a stiffening plate 8, an anchoring plate 7, an SMA (shape memory alloy) bar 6 and a sliding bolt hole 11, and the node structure is characterized in that the steel beam sleeve 5 is prefabricated according to the cross section size of the H-shaped steel beam 2 and is connected with the compound steel pipe concrete column 1 through an upper reinforcing ring plate and a lower reinforcing ring plate 4;
the brass friction plate 12 is welded at the web plate of the beam end; the steel beam sleeve 5, the brass friction plate 12 and the H-shaped steel beam 2 are tightly pressed and connected through a pre-tightening bolt 9; the steel beam sleeve 5 and the H-shaped steel beam 2 are respectively prefabricated with anchor plates 7, stiffening plates 8 are welded between the anchor plates 7 on one side to ensure the stability of the steel beam sleeve and the H-shaped steel beam, and then the SMA rods 6 are fixed at the anchor plates 7 on two sides through anchorage devices 13;
the flange plate 3 is welded on the outer steel tube of the compound steel tube concrete column 1, and the upper compound column and the lower compound column are connected through a flange bolt 10;

Compared with the traditional reinforced concrete column, the compound steel pipe concrete column 1 adopted by the invention is more friendly to an assembled frame structure.
Firstly, the adopted composite steel pipe concrete column 1 is connected through the upper flange plate and the lower flange plate 3, so that the assembly performance is better;

The designed node is completely symmetrical about the neutral axis, so that the performance of the node under the action of positive and negative bending moments is consistent. Taking the positive bending moment as an example, when the beam column slides relatively under the action of the positive bending moment, the high-strength bolt 14 and the SMA rod 6 at the flange of the steel beam share the tensile force, and the node shearing force is mainly borne by the high-strength bolt 14. Therefore, the deformation of the node is mainly concentrated on the high-strength bolt 14 and the SMA bar 6, and in the repair after the earthquake, the connection strength before the earthquake can be recovered only by simply heating or replacing the SMA bar 6 or loosening and replacing the high-strength bolt 14, so that the repair is convenient and quick.
In the friction energy dissipation design adopted by the invention, sliding bolt holes 11 are reserved at the flange and the web plate of the beam end, so that the relative sliding between the steel beam sleeve 5 and the steel beam is realized, and further, the friction effect is generated, and the friction energy dissipation is generated.

Meanwhile, due to the existence of the steel beam sleeve 5, the buckling of the part of the steel beam participating in friction caused by overlarge design of the sliding force is avoided, and the reliability of friction energy consumption is further ensured.
The SMA rod material 6 designed by the invention can provide enough bearing capacity, the anchoring end of the SMA rod material is fixed at the anchoring plates 7 at two sides through the anchorage device, and meanwhile, the diameter ratio of the threaded part and the smooth part is increased so as to avoid the wire material breakage problem possibly occurring at the anchoring end due to complex stress.
