8. The construction method of the external protective wall according to any one of claims 2 to 7, wherein: It includes the following steps: Step 1: Use BIM modeling software. According to the span and position of the external window (3) in the design, determine the position of the corbel (12) and issue a detailed drawing. Fix the corbel (12) on the main steel column (2) in the factory, and install the main steel beam (1) and the main steel column (2). Step 2: Install the integrated wall frame. First, install the connecting column (6) of the integrated wall frame. The connecting column (6) is fixed to the main steel beam (1) by welding. The connecting column (6) is welded to a steel plate (10) fixed to the lower floor slab (16) by chemical anchor bolts. Fix the upper steel lintel (7) and the lower steel lintel (8) on the corbel (12) of the main steel column (2). The connecting column (6) is welded to the upper steel lintel (7) and the lower steel lintel (8). Step 3: Install the ALC exterior wall panel (4), and fix the ALC exterior wall panel (4) within the grid space formed by the main steel beam (1), main steel column (2), connecting column (6), upper steel lintel (7), and lower steel lintel (8). Step 4: Install the sub-frame of the exterior window (3). The four sides of the sub-frame of the exterior window (3) are respectively welded and fixed to the upper steel lintel (7), lower steel lintel (8), and the connecting columns (6) on both sides of the exterior window (3) through the transition angle iron (9). Step 5: Weld and fix the adapter (13) to the upper steel lintel (7) and lower steel lintel (8), and fix the exterior curtain wall (5) to the adapter (13) through the back bolt hanging parts (14) to complete the installation construction.

9. The construction method of the external protective wall for installing both external windows and external curtain wall structures according to claim 8 is characterized in that: The upper part of the ALC exterior wall panel (4) between the main steel beam (1) and the upper steel lintel (7) is connected to the main steel beam (1) through a hook bolt, and the lower part is connected to the upper steel lintel (7) through a U-shaped clamp. The upper part of the ALC exterior wall panel (4) between the upper steel lintel (7) and the lower steel lintel (8) is connected to the upper steel lintel (7) through a hook bolt, and the lower part is welded and fixed to the lower steel lintel (8) through a U-shaped clamp. The upper part of the ALC exterior wall panel (4) between the lower steel lintel (8) and the lower floor slab (16) is connected to the lower steel lintel (8) through a hook bolt, and the lower part is fixed to the expansion bolt fixed on the lower floor slab (16) through a U-shaped clamp.
