[0047] S2: Install an X-shaped support frame 4 on the side of the steel structure box 1, and use fixing screws to fix the support frame 4 to the sides of the integrated board 3 on both sides.

[0049] When in use, first weld the steel support column 102 to the top of the base 101, then weld the installation frame 103 to the top of the steel support column 102, weld the keel 104 between the adjacent steel support columns 102 and inside the installation frame 103, install the door body 107 between two adjacent steel support columns 102, then install the fireproof board 102 on both sides of the keel 104 of the steel structure box 1, and install the tension screw 202 between the two adjacent installation holes 201 and the installation hole 105 corresponding to the keel 104.

In the groove 2 501, the position of the protective plate 2 5 is preliminarily defined, and then the locking frame 6 is connected to the two sides of the steel structure box 1 by using fixing screws to further define the position of the fireproof plate 2 5. At the same time, the positions of the sliding splicing seat 1 7 and the splicing seat 2 8 are adjusted to detect the installation position of the fireproof plate 2 5. When the fireproof plate 2 5 is not completely embedded in the side of the steel structure box 1, it is not in the same vertical plane as the side of the steel structure box 1, which will cause the splicing seat 1 7 and the splicing seat 2 8 to be unable to move, prompting the staff that the fireproof plate 2 5 is not installed in place; When it is necessary to dock adjacent steel structure boxes 1, the positions of splicing seat 1 7 and splicing seat 2 8 are adjusted according to the docking position so that the adjacent steel structure boxes 1 can be staggered and spliced, and the limiting bolt 901 is installed inside the through groove 109 so that the limiting bolt 901 is threadedly connected with the screw hole of the slide seat 9 to limit the position of the splicing seat 1 7 and the splicing seat 2 8. Then, one of the steel structure boxes 1 is lifted and moved from top to bottom so that the adjacent docking seat 701 and the docking groove 801 are engaged and docked together to complete the docking of the adjacent steel structure boxes 1.

Then, the fixing screw is used to fix the second fireproof board (5) on the steel structure box (1). The screws connect the locking frame (6) to the two sides of the steel structure box (1), further limiting the position of the second fireproof board (5), and at the same time sliding the positions of the first splicing seat (7) and the second splicing seat (8) to detect the installation position of the second fireproof board (5). When the second fireproof board (5) is not completely embedded in the side of the steel structure box (1), it is not in the same vertical plane as the side of the steel structure box (1), which will cause the first splicing seat (7) and the second splicing seat (8) to be unable to move; S3: When it is necessary to dock adjacent steel structure boxes (1), the positions of the splicing seat 1 (7) and the splicing seat 2 (8) are adjusted according to the docking position so that the adjacent steel structure boxes (1) can be staggered and spliced, and a limiting bolt (901) is installed inside the through groove (109) so that the limiting bolt (901) is threadedly connected to the screw hole of the sliding seat (9) to limit the position of the splicing seat 1 (7) and the splicing seat 2 (8), and then one of the steel structure boxes (1) is lifted and moved from top to bottom so that the adjacent docking seat (701) and the docking groove (801) are engaged and docked together, thereby completing the docking of the adjacent steel structure boxes (1).
