However, the scope of protection of this utility model is not limited to the specific embodiments described below.

[0038] refer to Figures 1-4 A steel structure column for prefabricated buildings, comprising a tubular column 11 and a connecting structure.

[0039] A cross-shaped support frame 12 is installed inside the tubular column 11. The cross-shaped support frame 12 has triangular grooves 13. The cross-shaped support frame 12 has a cross-shaped cross section, while the tubular column 11 has a square cross section. The four ends of the cross-shaped support frame 12 are respectively engaged with the four corners of the inner wall of the tubular column 11, so that the cross-shaped support frame 12 is tightly secured inside the tubular column 11, and the cross-shaped support frame 12 and the inner wall of the tubular column 11 form four triangular grooves 13 around it. The connecting structure includes a triangular pin 14, a connecting plate 15, and a connecting sleeve 21. The triangular pin 14 is inserted into the triangular groove 13 and engages with the triangular groove 13. The triangular pin 14 and the connecting plate 15 are located inside the connecting sleeve 21. The connecting plate 15 is fixedly connected to the triangular pin 14 and the connecting sleeve 21 respectively. The connecting sleeve 21 is fitted onto the inner wall of the tubular column 11. The cross-shaped support frame 12 has four triangular grooves 13, which are evenly distributed around the circumference of the cross-shaped support frame 12. Four triangular pins 14 are also provided, each corresponding to one of the four triangular grooves 13. By simultaneously inserting the four triangular pins 14 into the triangular grooves 13, the structural stability between the tubular column 11 and the connecting structure can be improved.

[0040] At least two tubular columns 11 are provided, arranged vertically. This allows for a combined vertical extension of multiple tubular columns 11, increasing the vertical extension length of the steel structure columns and making it suitable for multi-story prefabricated buildings. A connecting plate 15 is located in the middle of the triangular pin 14. The upper and lower sides of the connecting plate 15 are respectively engaged with two adjacent tubular columns 11. The upper and lower ends of the triangular pin 14 are inserted into the adjacent tubular columns 11. This ensures that the upper and lower ends of the triangular pin 14 can be inserted into the upper and lower tubular columns 11 respectively, guaranteeing the structural reliability between the upper and lower tubular columns 11 and the connecting structure.

[0041] The connecting sleeve 21 is equipped with a first fastener 22, which passes through the tubular column 11 and is threadedly connected to the triangular pin 14. The first fastener 22 is a screw, and its installation improves the structural stability between the connecting structure and the tubular column 11. The sliding sleeve 23 is equipped with a second fastener 24, which passes through the connecting sleeve 21 and the tubular column 11 and is threadedly connected to the triangular pin 14. The second fastener 24 is a bolt, and its installation improves the structural stability between the connecting structure and the tubular column 11. The sliding sleeve 23 is fitted onto the outer wall of the connecting sleeve 21, and the first fastener 22 and the second fastener 24 are located below and above the connecting plate 15, respectively. By connecting the first fastener 22 and the second fastener 24 to the two tubular columns 11 below and above the connecting plate 15, respectively, the overall structural reliability of the steel structure columns can be improved.

[0042] A beam support plate 31 is fixedly connected to the connecting sleeve 21. A sliding sleeve 23 is slidably connected to the connecting sleeve 21, and a beam pressure plate 32 is fixedly connected to the sliding sleeve 23. The beam pressure plate 32 is located above the beam support plate 31, and a limiting stud is provided between the beam pressure plate 32 and the beam support plate 31. The limiting stud passes through the crossbeam 41 and provides preload force on the beam pressure plate 32 and the beam support plate 31, so that the beam pressure plate 32 and the beam support plate 31 clamp the crossbeam 41, improving the structural reliability of the crossbeam 41. There are a total of 4 beam support plates 31 and 4 beam pressure plates 32, and each of the 4 beam support plates 31 and 4 beam pressure plates 32 corresponds to the other 41. The 4 beam support plates 31 and 4 beam pressure plates 32 can install 4 crossbeams 41, increasing the number of crossbeams 41 that can be installed. The beam pressure plate 32 is provided with an upper rib 33, which is fixedly connected to the sliding sleeve 23 and the beam pressure plate 32 respectively. The upper rib plate 33 improves the structural stability between the beam pressure plate 32 and the sliding sleeve 23. The beam support plate 31 is provided with a lower rib plate 34, which is fixedly connected to both the beam support plate 31 and the connecting sleeve 21. The lower rib plate 34 improves the structural stability between the beam support plate 31 and the connecting sleeve 21.

[0043] During assembly at the construction site, two cross support frames 12 are inserted into the interiors of two tubular columns 11, and one tubular column 11 is installed in the designated position. A connecting structure is installed on the upper end of the tubular column 11. The two ends of the triangular pin 14 extend from the two ends of the connecting sleeve 21, making it easy to first align the triangular pin 14 and insert it into the triangular groove 13. Then, push the triangular pin 14 downward. As the triangular pin 14 inserts downward into the triangular groove 13, the connecting plate 15 drives the connecting sleeve 21 to fit onto the outer wall of the tubular column 11 until the connecting plate 15 is engaged with the upper end of the tubular column 11. The first fastener 22 on the connecting sleeve 21 is screwed into the triangular pin 14, so that the triangular pin 14 and the connecting sleeve 21 clamp the tubular column 11. At the same time, the first fastener 22 passes through the tubular column 11, realizing the connection between the connecting structure and the first tubular column 11. Then, the second tubular column 11 is installed onto the connecting structure, positioned above the first tubular column 11. The position of the upper tubular column 11 is adjusted so that the upper end of the triangular pin 14 is inserted into the triangular groove 13 of the upper tubular column 11. The upper tubular column 11 is then pressed down, causing the connecting sleeve 21 to fit onto the outer wall of the upper tubular column 11 until the lower end of the upper tubular column 11 engages with the connecting plate 15. The crossbeam 41 is placed on the beam support plate 31. The sliding sleeve 23 is moved downwards until the beam pressure plate 32 presses against the upper surface of the crossbeam 41. The second fastener 24 on the sliding sleeve 23 is screwed into the triangular pin 14, clamping the upper tubular column 11 and the connecting sleeve 21 with the triangular pin 14 and the sliding sleeve 23. Simultaneously, the second fastener 24 passes through the tubular column 11, thus fixing the connecting structure to the upper and lower tubular columns 11. The crossbeam 41 is clamped by the beam support plate 31 and the beam pressure plate 32 to achieve the installation of the crossbeam 41.

[0044] This embodiment has the following advantages:

[0045] The cross support frame 12 can provide support to the tubular column 11 from inside, effectively improving the structural reliability of the tubular column 11.

[0046] A triangular groove 13 is formed between the cross support frame 12 and the tubular column 11. A triangular pin 14 is inserted into the triangular groove 13, which can achieve the effect of positioning and support between the connecting structure and the tubular column 11. While ensuring the stability of the positions of the upper and lower tubular columns 11, it can also effectively improve the structural stability between the connecting structure and the tubular column 11, and effectively improve the structural reliability of the steel structure column.

[0047] The connecting plate 15 can not only connect the triangular pin 14 and the connecting sleeve 21, but also transmit the supporting force of the upper and lower tubular columns 11. By connecting the connecting plate 15 and clamping the connecting sleeve 21 and triangular pin 14 of the tubular column 11 to transmit the load, it can effectively prevent the stress at the end face of the tubular column 11 from being too concentrated, and further improve the structural reliability of the steel structure column.
