[0027] When it is necessary to install several I-beams 3 and combined tubes 2 on the outer wall of the square tube steel 1, the staff first aligns the two combined tubes 2 with the two sides of the square tube steel 1, and then aligns the several docking threaded holes 200. When the square tube steel 1 and the two combined tubes 2 are fixed, the staff first aligns a load-bearing steel plate 4 with one of the combined tubes 2. At this time, the two rectangular steel rods 403 are inserted into the two rectangular grooves 2010, and then the docking screws 401 are rotated so that the docking screws 401 are threadedly connected with the several docking threaded holes 200.

[0035] The following is a detailed description of the working principle of the safety steel structure node component:

By inserting, the butt screws 401 that need to be rotated are effectively reduced, the operation difficulty is reduced, a certain amount of operation time is saved, and the work efficiency and applicability are improved. Repeating the above process once can fix the two combined tubes 2 to the outer wall of the square tube steel 1;

[0037] Then, a number of I-beams 3 are respectively inserted into the two positioning frames 203 and the four positioning half-frames 202, and one end of the I-beam 3 is against the combined tube 2. Then, the I-plate 5 is grabbed, and a number of insertion rods 501 are aligned with the corresponding socket 1 2030 and socket 2 300, and the I-plate 5 is pushed. At this time, a number of insertion rods 501 are slidably matched with socket 1 2030 and socket 2 300. When one end of the I-plate 5 is against the positioning half-frame 202 or the positioning frame 203, a number of mounting nuts 2 503 are threadedly sleeved on the fixing screw 2 502, and the mounting nuts 2 503 are squeezed and limited to the positioning half-frame 202 or the positioning frame 203. By inserting again, the difficulty of operation is further reduced, which is not only convenient for the staff to operate, but also can effectively improve work efficiency and has strong applicability.
