[0005] Furthermore, it also includes: a first stair section, the first stair section is connected to the outer wall of the building; a second stair section, the second stair section is connected to the inner wall of the building, and the average height of the second stair section is higher than that of the first stair section; a first stair section platform, the first stair section platform is arranged between the second stair section and the first stair section, and the first stair section platform is used to connect the second stair section with the first stair section.

[0006] Furthermore, the system further comprises: a second stair platform, the second stair platform being located at the top of the second stair. Furthermore, the height of the second stair platform is lower than the first roof structure plate. Furthermore, the system further comprises: a stairwell roof door opening, the stairwell roof door opening being located between the second roof structure plate and the second stair platform.

[0007] Furthermore, the structure further comprises: a third roof structural panel, the third roof structural panel being disposed on the side of the building interior wall opposite the second staircase. Furthermore, the average height of the third roof structural panel is lower than the second staircase landing. Furthermore, the structure further comprises: a stairwell exit staircase, the stairwell exit staircase being connected to the second staircase landing and disposed on the third roof structural panel.

[0008] Furthermore, the second stair platform is located directly below the second roof structure plate.

[0009] Furthermore, it also includes: a doorway canopy, which is arranged at the top of the doorway on the roof of the stairwell.

[0010] The beneficial effects of the utility model are:

[0011] 1. By lowering the height of the first roof structure plate and the third roof structure plate, the civil engineering cost is saved.

[0012] 2. Setting the stairwell rooftop away from the building's exterior wall can separate the stairwell rooftop from the building's exterior facade and gain space for entry and retreat, providing space for the arrangement of other structures. BRIEF DESCRIPTION OF THE DRAWINGS
