[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 In this embodiment of the utility model, a prefabricated wall panel with an integrated insulation layer includes a prefabricated wall panel 1. A clip 2 is provided on one side of the prefabricated wall panel 1, and a slot 3 is provided on the other side of the prefabricated wall panel 1. The clip 2 is embedded in the slot 3. The prefabricated wall panel 1 can be assembled by the action of the clip 2 and the slot 3. The prefabricated wall panel 1 is composed of an inner gypsum board 4, an outer gypsum board 6, and an insulation board 5. The insulation board 5 is located between the inner gypsum board 4 and the outer gypsum board 6. The insulation board 5 is composed of an insulation layer 11 and a reinforcing plate 18. A protruding strip 10 is provided on the inner side of the reinforcing plate 18. The reinforcing plate 18 and the insulation layer 11 are bonded together by a foaming adhesive layer 9. A serration 13 is provided on the outer side of the reinforcing plate 18. The serration 13 is embedded in the inner gypsum board 4 and the outer gypsum board 6. An inner protective layer 8 is provided on the inner side of the inner gypsum board 4, and an outer protective layer 7 is provided on the outer side of the outer gypsum board 6.

[0026] The reinforcing board 18 is either a wood fiberboard or a PVC board. The wood fiberboard solution utilizes its porous structure to absorb high-frequency sound waves, and the natural fibers and gypsum board form a damping matching layer to effectively attenuate structural sound transmission. The PVC board solution blocks the airborne sound transmission path through its closed-cell structure. Its thermal expansion characteristics are highly compatible with the foam layer 9, reducing the interface stress concentration caused by changes in ambient temperature. Both materials undergo surface treatment processes to enhance their adhesion to adjacent layers.

[0027] The insulation layer 11 is composed of filling tubes 14 and insulation filler 12. The filling tubes 14 are welded together side by side, and the insulation filler 12 is filled inside the filling tubes 14. The insulation layer 11 is composed of an array of filling tubes 14 and insulation filler 12. The circular cross-section filling tubes 14 are welded to form a honeycomb structure. This geometric design significantly improves the overall compressive strength. The filling tubes 14 are treated with anti-corrosion process to ensure structural stability in humid environments. The insulation filler 12 is set as either expanded perlite filler or foam glass filler. The expanded perlite is calcined at high temperature to form a closed microporous structure, and the internal air layer effectively blocks heat conduction. The foam glass is formed by sintering process to form a high closed-cell structure, which can still maintain stable heat insulation performance in humid environments. Both materials have low thermal conductivity and high weather resistance.

[0028] Both the outer protective layer 7 and the inner protective layer 8 consist of a fire-resistant layer 15, an anti-aging layer 16, and a self-cleaning layer 17. The fire-resistant layer 15 is attached to the outer side of the inner gypsum board 4 and the outer gypsum board 6. The anti-aging layer 16 is attached to the outer side of the fire-resistant layer 15, and the self-cleaning layer 17 is attached to the outer side of the anti-aging layer 16. The outer protective layer 7 and the inner protective layer 8 form a multi-layered protective system from high-temperature resistance to weather resistance and self-cleaning through the three-layer structure of the fire-resistant layer 15, the anti-aging layer 16, and the self-cleaning layer 17. The fire-resistant layer 15 uses... The coating is an intumescent fireproof coating. The anti-aging layer 16 is a fluorocarbon coating layer, and the self-cleaning layer 17 is a nano-silicon coating layer. The fireproof layer 15 expands when heated to form a carbonized layer, which blocks the heat transfer through physical expansion. The anti-aging layer 16 uses the high stability of fluorocarbon bonds to resist ultraviolet degradation and extend the service life of the material. The self-cleaning layer 17 uses the low surface energy characteristics of the nano-silicon coating to make it difficult for pollutants to adhere and achieve self-cleaning function. The three-layer structure forms a multi-protection system from high temperature resistance to weather resistance and self-cleaning.

[0029] The working principle and usage process of this utility model: The precast wall panel 1 adopts a sandwich structure. The inner gypsum board 4 and the outer gypsum board 6 are mechanically interlocked with the middle reinforcing plate 18 through a sawtooth structure. The reinforcing plate 18 is provided with protrusions 10 and sawtooth 13 on both sides, which are mechanically interlocked with the foam layer 9 to form a three-dimensional support network. This structure simultaneously achieves: the sawtooth 13 transmits structural shear force, the protrusions 10 increase interface friction, and the foam layer 9 provides chemical bonding. The three work together to construct a composite support system with both strength and toughness. The insulation layer 11 adopts a gradient density design. The change in medium density causes sound waves to refract and lose sound. Combined with the rigid skeleton of the reinforcing plate 18, it suppresses resonance transmission and forms a broadband sound insulation effect.

[0030] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
