[0002] At present, most subway depot buildings in the country are multi-story cast-in-place concrete frame structures. The exterior walls are constructed and plastered with aerated concrete blocks. The exterior wall insulation system uses conventional insulation materials such as foamed ceramic insulation board, extruded polystyrene board, and rock wool. However, ordinary aerated concrete block walls have many common quality defects, such as the following: (1) high porosity, high water absorption, low surface strength, and easy to be damaged; (3) high risk of leakage of aerated concrete block masonry; (4) common quality defects such as through joints, false joints, and blind joints are very easy to occur during the construction of aerated concrete block masonry, which is not conducive to quality control; (5) the construction period of aerated concrete block walls is long. Concrete tie beams and structural columns need to be set up during the construction process, and the walls need to be plastered. Summary of the Invention

[0016] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below with reference to specific illustrations. Example

[0017] An insulation system suitable for concrete exterior walls, such as Figure 1 , 2 As shown, it includes an inner wall panel 1 and an outer cover plate. The inner wall panel 1 is a fiber optic lining board, which is connected to the concrete outer wall 2 by several pre-embedded bolts. The outer end of the inner wall panel 1 is fixed with an insulating rock wool layer 3 using neutral silicone sealant.

[0018] Furthermore, such as Figure 1As shown, the outer cover plate includes a panel 5, on which a top plate 6 and two side plates 7 are provided; the panel 5 is located on the outside of the thermal insulation rock wool layer 3, and is connected to the concrete outer wall 2 by expansion bolts through several horizontal and vertical stiffening ribs 8. The inside of the stiffening ribs 8 is provided with a double layer of steel mesh 9. One end of the stiffening rib 8 is fixedly connected to the panel 5 through the pre-embedded part of the steel mesh 9, and the other end of the stiffening rib 8 passes through the thermal insulation rock wool layer 3 and is fixedly connected to the expansion bolts passing through the inner wall panel 1.

[0019] Furthermore, such as Figure 1 As shown, the tops of both side panels 7 are connected to the inner wall panel 1 and the thermal insulation rock wool layer 3 via a first post-embedded component. The first post-embedded component includes a first U-shaped embedded component 10 and a U-shaped hanger 11. The first U-shaped embedded component 10 is located within the inner wall panel 1 and the thermal insulation rock wool layer 3. One side of the U-shaped hanger 11 is bolted to the first U-shaped embedded component 10, and the other side of the U-shaped hanger 11 is bolted to the side panel 7. Limiting baffles are provided at the bottom of both side panels 7 on the thermal insulation rock wool layer 3. These limiting baffles are made of angle steel and are bolted to the thermal insulation rock wool layer 3. The first U-shaped embedded component 10, the U-shaped hanger 11, and the limiting baffles constrain the loosening of the outer cover plate in all directions.

[0020] Furthermore, such as Figure 2 As shown, the top plate 6 is placed on the upper side of the thermal insulation rock wool layer 3. The top plate 6 is connected to the thermal insulation rock wool layer 3 through a second post-installed embedded part. The second post-installed embedded part includes a second U-shaped embedded part 12. Both sides of the second U-shaped embedded part 12 are connected to the connecting part 13 by bolts. The second U-shaped embedded part 12 is made of channel steel, and the connecting part 13 is made of angle steel. A rib baffle 14 is provided at the bottom center of the top plate 6. According to the slope of the top plate 6, one connecting part 13 is connected to the center of the top plate 6 through the rib baffle 14 and bolts to prevent the top plate 6 from moving downward. The other connecting part 13 is directly connected to the top plate 6 by bolts to adjust the slope of the top plate 6. A Z-shaped waterproof aluminum plate 15 is provided at the junction of the top plate 6 and the thermal insulation rock wool layer 3. The waterproof aluminum plate is fixed at the junction of the top plate 6 and the thermal insulation layer with neutral silicone sealant.
