[0022] Hereinafter, an embodiment of the outwrapped steel column base node structure of the present invention will be described with reference to the accompanying drawings.

[0023] Figure 1-5 The utility model shows an outsourced steel column foot node structure of an embodiment of the present invention, which includes a steel column body 2 installed on the top of a cement platform 1, and a plurality of upright steel bar bodies 3 extending to the top of the cement platform 1 are pre-embedded in the cement platform 1. The ends of the upright steel bar bodies 3 embedded in the cement platform 1 are set as right-angle ends 10. Through the setting of the right-angle ends 10, the connection between the upright steel bar bodies 3 and the cement platform 1 can be strengthened, and the stability of the upright steel bar bodies 3 embedded in the cement platform 1 is improved. The plurality of upright steel bar bodies 3 are arranged around the steel column body 2, and the surfaces of the plurality of upright steel bar bodies 3 are sleeved with a plurality of steel bar frame bodies 4, which are welded to the upright steel bar bodies 3. The four sides of the steel column body 2 and the upright steel bar body 3 are all provided with internal support components 5. The internal support components 5 include short steel bars 51 that are against the surface of the steel column body 2, and a fixing seat 53 is welded on one side of the short steel bar 51. A threaded sleeve 54 is rotatably connected to one side of the fixing seat 53, and a threaded rod 55 is threadedly connected to the inner cavity of the threaded sleeve 54. The threaded rod 55 is welded at one end away from the short steel bar 51. A long steel bar 56 is connected, and the long steel bar 56 is against one side of the multiple upright steel bar bodies 3. An annular groove 57 is provided on one side of the fixing seat 53. The end of the threaded sleeve 54 is fixedly connected to a rotating ring 58 that is rotatably connected to the inner cavity of the annular groove 57. Both sides of the inner cavity of the fixing seat 53 are fixedly connected to the limiting strip 59. Both sides of the surface of the threaded rod 55 are provided with a limiting groove 510 that slides on the surface of the limiting strip 59. Through the use of the limiting strip 59 and the limiting groove 510, the threaded rod 55 will move during the movement of the threaded rod. The limiting groove 510 on the surface of the threaded rod 55 slides on the surface of the limiting strip 59 to guide and limit the movement of the threaded rod 55, ensuring that the threaded rod 55 will not rotate with the rotation of the threaded sleeve 54. Multiple round head bolts 6 are welded on the four surfaces of the steel column body 2, and a base plate 7 is welded on the bottom of the steel column body 2. Multiple embedded bolts 8 are embedded in the top of the cement platform 1. Multiple embedded bolts 8 fix the steel column body 2 to the top of the cement platform 1 through the base plate 7. Multiple reinforcing ribs 9 are welded between the steel column body 2 and the base plate 7.

[0024] Working principle: When using the present invention, the user fixes the steel column body 2 above the cement platform 1 through the embedded bolts 8 and the base plate 7, then picks up the inner support assembly 5, so that the short steel bar 51 rests on the steel column body 2 between the upper and lower round head bolts 6, and then rotates the threaded sleeve 54. The threaded rod 55 moves due to the thread, and the threaded rod 55 drives the long steel bar 56 to move and rest on multiple upright steel bar bodies 3 until multiple upright steel bar bodies 3 are in an upright state, and then the steel bar frame body 4 is put on the surface of the upright steel bar body 3, welded and bundled, and finally the formwork is erected and poured.

[0025] To sum up: the outsourced steel column foot node structure, by inserting the short steel bar 51 between the steel column body 2 and the upright steel bar body 3, rotating the threaded sleeve 54, the threaded rod 55 moves due to the thread and drives the long steel bar 56 to press against the upright steel bar body 3, so that multiple upright steel bar bodies 3 can be stably erected without inward tilting, which facilitates the steel bar frame body 4 to be welded and tied on the surface of multiple upright steel bar bodies 3, and the purpose of using the internal support structure to ensure the stability of the upright steel bars, speed up the welding or bundling of the steel cage, and improve efficiency.
