[0024] The effect achieved by the entire embodiment 1 is that, when in use, the stair frame 4 is first accurately installed on the preset first fixing plate 2 and the second fixing plate 3, and then, the second threaded rod 9 is passed through the connecting groove 6, which is pre-designed on the connecting plate 5, the first fixing plate 2 and the second fixing plate 3. Through this step, the second threaded rod 9 can effectively connect the stair frame 4 with the first fixing plate 2 and the second fixing plate 3, and then, the second threaded rod 9 is fixed with the first limiting nut 10. By rotating the first limiting nut 10, it is tightly fitted on the fixing plate, thereby ensuring the firmness of the second threaded rod 9. In order to further strengthen the connection between the staircase and the wall panel 1, the reinforcement plate 7 is installed on the wall panel 1 using the first threaded rod 8. This step not only enhances the overall stability of the stairs, but also improves its safety in use. Subsequently, the stair board 11 is placed The stair tread 11 is placed on the installed stair frame 4 to ensure accurate alignment between the stair tread 11 and the frame to ensure the flatness and stability of the stairs. Then, the stair tread 11 is fixed by the third threaded rod 13.

Through this step, the second threaded rod 9 can effectively connect the stair frame 4 with the first fixing plate 2 and the second fixing plate 3, and then use the first limiting nut 10 to fix the second threaded rod 9. By rotating the first limiting nut 10, it is tightly fitted on the fixing plate, and then the first threaded rod 8 is used to install the reinforcement plate 7. Install it on the wall panel 1, then place the stair board 11 on the installed stair frame 4, then use the third threaded rod 13 to fix the stair board 11, pass the third threaded rod 13 through the connecting column 12 on the stair board 11 and the corresponding position of the stair frame 4, and fix the third threaded rod 13 tightly between the stair board 11 and the frame by rotating the second limit nut 14. When installing multiple stair boards 11, the above operation can be repeated, and then the stair frame 4 on the other side can be driven by pulling the handle 19.
