[0049] The window frame installation surface 201, the step surface 202 and the window cover installation surface 101 are covered with a waterproof layer 3, and the exterior wall door and window cover 4 is installed on the waterproof layer 3 at the position of the window cover installation surface 101; the inner side end of the exterior wall door and window cover 4 is bent over the joint between the step surface 202 and the window cover installation surface 101, and extends toward the window frame installation surface 201 along the step surface 202. A continuous waterproof layer 3 is set at the joint between the prefabricated integrated wall 1 and the interior wall door and window cover 2, and is shielded by the exterior wall door and window cover 4 to achieve a sealing effect.

[0050] The inner wall door and window frames 2 may specifically be made of OSB / 4 boards.

[0051] See also Figure 1 , a window frame 5 is fixed in the window frame installation surface 201 by fasteners 10, and after being fixed, a foam glue 9 is filled between the window frame installation surface 201 and the window frame 5, and a sub-frame 6 is installed on the outer wall side of the window frame 5, and a sealing strip 7 is provided on the sub-frame 6, and the sealing strip 7 is sealed and attached to the waterproof layer 3 at the position of the step surface 202, and the outer wall door and window frame 4 extends to the sealing strip 7. The sub-frame 6 with the sealing strip 7 is installed on the window frame 5, and the sealing strip 7 is attached to the vertical step surface 202, which further plays a sealing effect.

[0052] The fastener 10 may be a self-tapping screw.

[0053] The sub-frame 6 can be set on one side, which is easy to install;

[0054] See also Figure 3 , the inner wall of the inner wall door and window frame 2 is away from the vertical surface of the inner wall of the prefabricated integrated wall 1 ( Figure 1 , 3 The left side in the middle is the inner wall surface, and the side with the outer wall door and window frame 4 is the outer wall surface) and a gradient groove 203 is cut out on one side, and a gradient difference is also formed between the gradient groove 203 and the window frame installation surface 201. The water inside adheres to the gradient groove 203 and will not directly soak into the foam glue 9.

[0055] See also Figure 3 In the above embodiment, the inner side of the prefabricated integrated wall 1 is pre-embedded with embedded parts 8, and the embedded parts 8 are fixedly connected to the inner wall door and window frames 2 through fasteners.

[0061] During the entire installation and layout process: first, use the tooling mold to reserve the door and window openings on the prefabricated integrated wall 1, then use self-tapping screws to fix the OSB / 4 board around the opening to form the inner wall door and window frame 2, pad the opening circle, and then use waterproof paint to make a waterproof layer 3 at the opening;

[0062] The prefabricated exterior wall door and window covers 4 are installed in the waterproof door and window openings using structural sealant and self-tapping screws;
