Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Please refer to Figures 1-2, the utility model provides a technical solution:

Embodiment 1:

A composite wall structure panel comprises a structural frame 1, wherein a cavity 3 for filling with an insulation layer 2 is provided in the structural frame 1, an outer wall panel 4 and an inner wall panel 5 are respectively installed on the end faces of the structural frame 1 on both sides of the insulation layer 2, a substrate 6 is further arranged in the interlayer between the insulation layer 2 and the outer wall panel 4, an aluminum foil layer 7 is glued to the side of the substrate 6 close to the insulation layer 2, the aluminum foil layer 7 wraps the edge of the substrate 6 to form a 匚-shaped edge sealing structure, the substrate 6 and the structural frame 1 are fixed by air nails 12 and glue, and the outer wall panel 4 and the substrate 6 are fixedly connected by glue.

In this embodiment, the structural frame 1 is made of galvanized steel material. The advantage of adding a galvanized layer is that the galvanized layer can effectively prevent the steel material from being oxidized and corroded, forming a physical barrier to isolate the steel from oxygen, water and other corrosive substances in the environment, thereby extending the service life of the steel. At the same time, the galvanized layer can make the steel have good weather resistance, and can resist the erosion of natural environments such as ultraviolet radiation, high temperature, rain, snow, etc., reducing the aging rate of the steel. In addition, it can also improve the aesthetics of the steel. The structural frame 1 is welded and formed by a cold-bent galvanized steel frame 8 and a number of equidistantly arranged cold-bent galvanized cross frames 9. The arrangement of the cold-bent galvanized cross frames 9 can greatly improve the strength of the structural frame 1, and a space for filling the insulation layer 2 is opened in the structural frame 1. The cavity 3 can play a role of heat insulation and sound insulation by filling the insulation layer 2. The inner and outer layers of the structural frame 1 are also installed with wall outer panels 4 and wall inner panels 5. Both of them adopt steel plate structure, which can effectively protect the laminated structure wrapped inside. A base plate 6 is also arranged in the interlayer between the insulation layer 2 and the wall outer panel 4. The wall outer panel 4 is installed and fixed by the base plate 6. The base plate 6 is connected to the structural frame 1 by air nails 12 and adhesive connection, and the wall outer panel 4 and the base plate 6 are fixedly connected by adhesive connection. This installation method makes the surface of the wall outer panel 4 without any punching holes and fixing parts, ensuring the beauty of the panel installation. The adhesive connection method is used for bonding, and its bonding strength is high, irreversible and durable. In addition, the wall outer panel 4 The colored steel flat plate formed by a single-color coating, a stone coating or a wood grain coating further enhances the aesthetics of the exterior facade through the setting of the coating, and at the same time protects the wall outer panel 4 of the steel structure. Furthermore, since the substrate 6 serves as a bonding mechanism for the wall outer panel 4, the stability of its structure determines the stability of the connection of the wall outer panel 4. In order to ensure the lightness and stability of the substrate 6, the substrate 6 is cut and formed from a cement fiber board, a calcium silicate board or a gypsum board, and at the same time, an aluminum foil layer 7 is used to further protect the substrate 6 through bonding, and the aluminum foil layer 7 is further used to wrap the edge of the substrate 6 to form a 匚-shaped edge sealing structure, which greatly improves the moisture-proof, mildew-proof and deformation-proof properties of the substrate 6. The stability of the substrate 6 structure directly leads to the long-term and stable attachment of the wall outer panel 4. On the surface of the substrate 6, the substrate 6 and the wall outer panel 4 are connected by gluing. The stable structure formed by the adhesive can prevent water vapor from penetrating into the surface of the substrate 6. Furthermore, the wall outer panel 4 and the substrate 6, the substrate 6 and the aluminum foil layer 7, and the substrate 6 and the structural frame 1 are glued and compounded by hot melt adhesive to form an adhesive layer 11. Since hot melt adhesive has a fast bonding function and has good durability and heat resistance, it can effectively bond different materials and is widely used in the field of industrial production. In summary, through the combination of welding, air nails, hot melt adhesive bonding and other connection methods, a stable structure is formed to bear various loads together, thereby greatly reducing the amount of structural steel; the integrated form has high installation efficiency and low overall cost.

Embodiment 2:

A plurality of equidistantly arranged bolt connection holes 10 are provided on both sides of the cold-bent galvanized steel frame 8 , and adjacent cold-bent galvanized steel frames 8 are connected by bolts passing through corresponding bolt connection holes 10 .

The joint between the inner wall panel 4 and the wall body is also filled with a thermoplastic polyurethane joint layer or a joint glue filling layer.

In this embodiment, adjacent composite wall structural panels are bolted together through bolt connection holes 10 provided on the cold-bent galvanized steel frame 8. The bolting method facilitates installation and disassembly, and the connection is relatively stable. In order to further improve the sealing performance of adjacent composite wall structural panels, sealant may be applied to the joints where adjacent composite wall structural panels are connected, thereby isolating and protecting the joints. The joints between the wall inner panel 4 and the wall are also filled with a thermoplastic polyurethane joint layer or a joint glue filling layer, wherein the thermoplastic polyurethane joint layer is bonded to the wall inner panel 4 by hot-melt technology, and the flexibility of the thermoplastic polyurethane material can effectively solve the risk of crack leakage at the joints caused by thermal expansion and contraction, or a joint glue filling layer is formed by filling with a joint glue having good sealing, adhesion and weather resistance, to ensure that it has reliable anti-leakage performance.

Embodiment three:

The thermal insulation layer 2 is evenly laid in the cavity 3 formed by the structural frame 1 by filling with a rock wool layer, a glass wool layer or an aerogel wool layer.

In this embodiment, the thermal insulation layer 2 is composed of a rock wool layer, a glass wool layer or an aerogel wool layer, all of which can effectively reduce the overall mass of the composite wall, and at the same time have the effects of shock absorption, vibration prevention, sound insulation and heat insulation.

Embodiment 4:

The insulation layer 2 is injected into the cavity 3 formed by the structural frame 1 by pouring and filling polystyrene particle resin mortar or perlite resin mortar on site. A pouring hole for filling the insulation layer into the cavity 3 is opened at the edge of the structural frame 1.

In this implementation, the insulation layer 2 is filled by on-site pouring, which can be performed according to the specific installation status of the composite wall structure panel. The molding and use time of the insulation layer 2 is shorter, so that it has the best shock-absorbing, shock-proof, sound-insulating and heat-insulating properties after installation.

Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
