[0002] With the continuous improvement of the construction industry's requirements for energy conservation, environmental protection, green buildings and industrialized construction, prefabricated buildings have gradually become an important development direction in the construction field. In prefabricated buildings, exterior wall panels are an important part of the building envelope structure. Their design and performance directly affect the building's thermal insulation, waterproofing, fire prevention and construction efficiency and other key indicators. Traditional exterior wall construction methods usually use wet operations, that is, the construction of the exterior wall is gradually completed on site through masonry, plastering and painting.

[0023] In the above-mentioned components, tight connection is used to ensure that the mounting plates on both sides and the support frame body form a stable overall structure. The top and bottom ends of the two exterior wall panel support frame bodies 2 are fixedly connected with a stabilizing frame 3. The stabilizing frame 3 is made of high-strength metal and is firmly connected to the support frame body by welding, thereby further enhancing the supporting force and anti-deformation ability of the exterior wall panel support frame body 2 in the vertical and horizontal directions.

[0024] Preferably, the locking plate 406 is rotatably connected to the inner wall of the second mounting groove 403 , a transmission rod 407 is fixedly connected to the top of the locking plate 406 , and the locking rod 413 is inserted into the interior of the locking hole 411 .

[0025] Among the above components, the transmission rod 407 is made of high-strength material and is used to transmit the rotational force of the locking plate 406 and maintain its stability.

The overall design fully considers the construction convenience and efficiency, and provides an efficient solution for the promotion and application of prefabricated exterior wall panels.

[0027] Embodiment 2: On the basis of the first embodiment, a composite structure 1 is provided inside the exterior wall panel bearing frame, and the composite structure 1 includes an exterior finishing layer 109, a flexible interface layer 108, a waterproof layer 107, an air microcirculation layer 106, a thermal insulation layer 105, a honeycomb insulation cavity layer 104, a load-bearing base layer 103 and an interior finishing layer 102 arranged from the outside to the inside. The exterior finishing layer 109 is made of an aluminum-magnesium-manganese alloy plate and a fiber-reinforced cement plate, and the exterior finishing layer 109 is connected to the flexible interface layer 108 by an elastic adhesive with high bonding strength.

[0028] Preferably, the flexible interface layer 108 is composed of a polymer rubber material and a shear-resistant reinforced grid, and is used to buffer thermal expansion and contraction stress and prevent interlayer cracking.

[0029] Among the above components, the flexible interface layer 108 adopts a composite structure design of a polymer rubber material and a shear-resistant reinforced grid. The rubber material has excellent elasticity and durability, and can effectively absorb the expansion and contraction stress caused by changes in environmental temperature differences; the shear-resistant reinforced grid provides additional tensile strength and stability through a mesh structure, thereby avoiding cracking or peeling of the exterior finishing layer 109 and the waterproof layer 107 due to stress concentration. The flexible interface layer 108 also has excellent adhesion, which can ensure a close bond between the multi-layer structure and extend the overall service life of the exterior wall panel, and is particularly suitable for environmental conditions with large temperature differences.

[0030] Preferably, the waterproof layer 107 is made of a self-repairing polymer waterproof membrane.

[0031] Among the above components, the waterproof layer 107 adopts a self-repairing polymer waterproof membrane, the material of which contains active segments that can heal automatically. When the surface of the waterproof membrane is partially damaged due to mechanical damage or microcracks, the segments will repolymerize under certain conditions and restore the complete waterproof performance. The polymer waterproof membrane has excellent flexibility and tensile strength, and can adapt to the deformation of the exterior wall panel without affecting its waterproof function. At the same time, the surface of the waterproof membrane has been weather-resistant treated, which can resist ultraviolet rays, acid rain and wind and sand erosion for a long time, significantly improving the waterproof durability and environmental adaptability of the exterior wall panel.

[0032] Preferably, the waterproof layer 107 and the air microcirculation layer 106 are bonded in dots to form local gaps, and the air microcirculation layer 106 includes air guide grooves and ventilation ducts to achieve air convection and avoid moisture accumulation inside the wall.

[0033] In the above-mentioned components, a point bonding design is adopted between the waterproof layer 107 and the air microcirculation layer 106. By forming evenly distributed local gaps between the two layers, the stability of the structure is guaranteed and the air is allowed to flow freely. The air microcirculation layer 106 includes a plurality of air guide grooves distributed along the direction of the wall panels and ventilation channels that penetrate the structure, which can form natural convection and effectively discharge moisture inside the wall to prevent problems such as reduced thermal insulation performance or moldy walls due to moisture accumulation. This design not only enhances the thermal insulation stability of the exterior wall panels, but also extends the durability of the building structure. It is particularly suitable for humid areas or rainy environments.

[0034] Preferably, the thermal insulation layer 105 adopts a layered design of an outer high-density polyurethane rigid foam board and an inner low-density rock wool board. Among the above components, the outer side of the insulation layer 105 is made of high-density polyurethane rigid foam board, which has low thermal conductivity and high density, can provide excellent thermal insulation performance, and has good moisture-proof ability, effectively blocking the invasion of external moisture; the inner side is made of low-density rock wool board, which has excellent fire resistance and sound absorption effect, and can meet strict fire safety standards. The layered design fully combines the advantages of different insulation materials, so that the insulation layer 105 has both efficient thermal insulation and fire resistance, sound absorption and durability, thereby significantly improving the comprehensive performance of the exterior wall panels under different environmental conditions.

[0035] Preferably, the thermal insulation layer 105 is connected to the honeycomb thermal insulation cavity layer 104 through an embedded frame. The honeycomb thermal insulation cavity layer 104 is composed of a plurality of micro honeycomb air cavities filled with inert gas to reduce heat conduction.

[0036] In the above-mentioned components, the thermal insulation layer 105 and the honeycomb thermal insulation cavity layer 104 are fixedly connected by an embedded frame design. The frame is made of high-strength engineering plastics, which can reduce the thermal bridge effect while ensuring a firm connection. The honeycomb thermal insulation cavity layer 104 is composed of micro honeycomb air cavities. Each honeycomb cavity unit is filled with an inert gas such as argon or carbon dioxide to further reduce the thermal conductivity, thereby effectively reducing the heat transfer inside and outside the wall. The honeycomb structure also has excellent mechanical strength and stability, which can enhance the compressive resistance and durability of the exterior wall panels, while further improving the overall thermal insulation effect.

[0037] Preferably, the load-bearing base layer 103 is made of a lightweight concrete slab.

[0038] Among the above-mentioned components, the load-bearing base layer 103 is made of lightweight concrete panels. The introduction of a pore structure in the material significantly reduces the overall weight, which not only reduces the building load but also facilitates construction and transportation. The lightweight concrete panels have high strength and rigidity, and can provide reliable support to ensure the stability and safety of the exterior wall panels. In addition, their internal structure has good durability and frost resistance, and can maintain a long service life under extreme climatic conditions. At the same time, they have certain fire resistance and meet the high requirements of modern buildings for structural materials.

[0039] Preferably, the interior surface layer 102 is made of a coated metal plate, the surface of which is treated with mildew and antibacterial treatment, and is connected and fixed to the load-bearing base layer 103 by magnetic adsorption.

[0040] Among the above components, the interior surface layer 102 is made of coated metal plates. The surface of the metal plates is treated with special coatings and has excellent mildew and antibacterial properties. It can effectively inhibit the growth of bacteria and mold, and is suitable for building scenes with high humidity or high hygiene requirements, such as hospitals or food processing plants. The interior surface layer 102 and the load-bearing base layer 103 are connected by magnetic adsorption, and the embedded magnetic elements ensure firm assembly, while facilitating disassembly and replacement. This design significantly improves the convenience of construction and the efficiency of later maintenance, allowing the exterior wall panels to quickly adapt to the needs of different scenes while extending their service life.

[0041] When working: the outer surface layer 109 is made of aluminum-magnesium-manganese alloy plate and fiber-reinforced cement board, which has excellent corrosion resistance and weather resistance. It is connected to the flexible interface layer 108 through an elastic adhesive with high bonding strength. The flexible interface layer 108 is composed of polymer rubber material and anti-shear reinforced grid, which can buffer the stress caused by thermal expansion and contraction and prevent interlayer cracking. The waterproof layer 107 is made of a self-repairing polymer waterproof membrane. Its micro-crack repair function ensures a long-term waterproof effect, and forms a local gap with the air microcirculation layer 106 through point bonding. The air guide grooves and ventilation channels in the air microcirculation layer 106 can realize natural convection to avoid moisture accumulation affecting the thermal insulation performance. The thermal insulation layer 105 adopts a layered design of high-density polyurethane rigid foam board on the outside and low-density rock wool board on the inside to achieve the dual effects of moisture-proof and fire-proof, and is connected to the honeycomb insulation cavity layer 104 through an embedded frame. The honeycomb insulation cavity layer 104 is composed of micro-honeycomb air cavities filled with inert gas, which effectively reduces heat conduction. The load-bearing base layer 103 adopts fiber-reinforced cement board or lightweight concrete board to provide stable support.

[0042] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the application should be included in the protection scope of the present application.
