Description

High-strength self-insulating prefabricated wall panel construction and energy-saving wall structure including it Technical Field

[0001] This utility model relates to the field of building energy-saving and thermal insulation technology, and in particular to a high-strength self-insulating prefabricated wall panel structure and an energy-saving wall structure including the same. Background Technology

[0002] Prefabricated construction is a major trend in current building development. Prefabricated buildings are characterized by being green, energy-saving, and environmentally friendly. Strengthening research and vigorously developing prefabricated construction is of great significance for protecting our living environment. External wall panels or infill wall panels are commonly used in prefabricated buildings. To meet building energy conservation requirements, multi-layer composite prefabricated wall panels are often used.

[0003] Multi-layer composite wall panels typically consist of autoclaved aerated concrete (AAC) panels on both sides and an insulation layer in the middle. However, due to the generally poor insulation performance of AAC panels (usually around 0.14–0.16 W / (m·K)), the overall thickness of the wall panels is often too thick to meet energy-saving requirements, resulting in significant weight and potential safety hazards such as falling and delamination. Furthermore, to prevent separation between the multiple layers and ensure connection strength, connectors are often used, but these connections are often weak, inevitably leading to delamination. Additionally, the insulation material itself has low strength, and the AAC panels themselves also have limited strength, making the insulation layer prone to deformation or damage during transportation and hoisting. This can lead to rainwater infiltration and compromised energy-saving insulation performance.

[0004] The patent "A Thermal Insulation Wall Material and Its Manufacturing Process" (Patent No.: ZL202010085174.8) discloses a novel wall material with high compressive strength (above 2.8 MPa), fire resistance (A2 fire rating), and good thermal insulation performance. Although it outperforms autoclaved aerated concrete products in terms of thermal insulation effect, volumetric water absorption rate, and dry density (self-weight) at the same strength level, its thermal conductivity is still relatively high, resulting in only average thermal insulation performance as a self-insulating wall material. To meet the multi-dimensional requirements of lightweight building, energy conservation and emission reduction, and fire safety, a new type of wall panel construction system is urgently needed.

[0062] The following description of the embodiments is with reference to the accompanying drawings, which illustrate specific embodiments in which the present invention can be implemented.

[0063] Example 1

[0064] As shown in Figures 1, 2, and 3, this embodiment discloses an energy-saving wall structure, which includes a high-strength self-insulating prefabricated wall panel structure. The high-strength self-insulating prefabricated wall panel structure includes a wall panel body 1 and several connecting fasteners 2. The wall panel body 1 includes an inner self-insulating wall panel 13, a high-efficiency insulation layer 12, and an outer self-insulating wall panel 11 arranged sequentially from the inside out. The connecting fasteners 2 pass through the high-efficiency insulation layer 12 and connect to the inner self-insulating wall panel 13 and the outer self-insulating wall panel 11, so that the inner self-insulating wall panel 13, the high-efficiency insulation layer 12, and the outer self-insulating wall panel 11 are connected in a multi-layer structure by the several connecting fasteners 2. The inner self-insulating wall panel 13, the high-efficiency insulation layer 12, and the outer self-insulating wall panel 11 are reliably connected by the several connecting fasteners 2, effectively preventing falling and greatly improving the safety and stability of the high-strength self-insulating prefabricated wall panel structure.

[0065] The thermal conductivity of the high-efficiency insulation layer 12 is better than that of the inner self-insulating wall panel 13 and the outer self-insulating wall panel 11. Both the inner self-insulating wall panel 13 and the outer self-insulating wall panel 11 are composed of organic-inorganic composite insulation materials and / or polyurethane materials. The organic material in the organic-inorganic composite insulation material is expandable polystyrene particles. The fire rating of both the inner self-insulating wall panel 13 and the outer self-insulating wall panel 11 reaches A2 level or above. The compressive strength of both the inner self-insulating wall panel 13 and the outer self-insulating wall panel 11 reaches 3.5MPa or above. The volume water absorption rate of both the inner self-insulating wall panel 13 and the outer self-insulating wall panel 11 is ≤15%. The thickness of the outer self-insulating wall panel 11 is 50mm or above. The inner self-insulating wall panel 13 and the outer self-insulating wall panel 11 have a fire resistance rating of A2 or higher, and the outer self-insulating wall panel 11 has a thickness of 50mm or more. This ensures that the high-strength self-insulating prefabricated wall panel structure, after being combined with the high-efficiency insulation layer 12, effectively meets both fire resistance and insulation requirements. Both the inner and outer self-insulating wall panels 13 and 11 have a compressive strength of 3.5MPa or higher, providing reliable material strength support when used as wall panel components. The volumetric water absorption rate of both the inner and outer self-insulating wall panels 13 and 11 is ≤15%, effectively preventing water leakage and ensuring the long-term effectiveness of the insulation performance of the high-strength self-insulating prefabricated wall panel structure. The thermal conductivity of the high-efficiency insulation layer 12 is better than that of the inner self-insulating wall panel 13 and the outer self-insulating wall panel 11, which significantly improves the insulation performance and optimizes the overall insulation effect of the high-strength self-insulating prefabricated wall panel structure. This achieves fire safety, flame retardancy and fire prevention for the high-strength self-insulating prefabricated wall panel structure, while also ensuring excellent insulation performance.

[0066] The energy-saving wall structure also includes a building frame 10 and several wall-connecting components 20. The two ends of the wall-connecting components 20 are respectively connected to the top or bottom of the building frame 10 and the wall panel body 1. The top and bottom of the high-strength self-insulating prefabricated wall panel structure are installed and connected to the building frame 10 through several wall-connecting components 20, so as to achieve reliable and convenient installation.

[0067] The compressive strength of the outer self-insulating wall panel 11 reaches 5.0 MPa or more. By ensuring that the thickness of the outer self-insulating wall panel 11 is 50 mm or more and the compressive strength is 5.0 MPa or more, the strength of the outer self-insulating wall panel 11 is further improved, which can increase the inherent strength and impact resistance of the high-strength self-insulating prefabricated wall panel structure and meet the reliability and safety requirements under long-term use conditions.

[0068] The compressive strength of the inner self-insulating wall panel 13 reaches 5.0 MPa or higher, and the thickness of the inner self-insulating wall panel 13 reaches 100 mm or higher. The compressive strength of the inner self-insulating wall panel 13 (reaching 5.0 MPa or higher) provides reliable material strength support for its application as an exterior wall cladding, and its thickness meets relevant fire protection design requirements, fundamentally eliminating fire hazards to both the material and the building, and further enhancing the material's strength and thickness. Simultaneously, it increases the structural integrity of the high-strength self-insulating prefabricated wall panel structure and the reliability of the connection between the high-strength self-insulating prefabricated wall panel structure and the main building frame 10.

[0069] Both the inner self-insulating wall panel 13 and the outer self-insulating wall panel 11 are composed of organic-inorganic composite insulation materials and / or polyurethane materials with a fire resistance rating of A2 or higher. In the organic-inorganic composite insulation material, the inorganic material is wrapped around the organic material. By wrapping the inorganic material around the organic material, it is possible to ensure that, with the same thickness of insulation material, the fire resistance reaches A2 level, the strength meets the relevant product standard requirements, and it is lightweight, eliminating the need for additional inorganic boards to enhance its strength and fire resistance.

[0070] Preferably, both the inner self-insulating wall panel 13 and the outer self-insulating wall panel 11 are made of graphene insulation material, which effectively ensures the insulation and fire resistance of the high-strength self-insulating prefabricated wall panel structure and greatly improves the safety and stability of the high-strength self-insulating prefabricated wall panel structure.

[0071] The high-efficiency insulation layer 12 includes one or more of the following: polyurethane foam, polyurethane insulation board, EPS polystyrene board, XPS extruded polystyrene board, vacuum insulation board, graphite EPS polystyrene board, graphite XPS extruded polystyrene board, aerogel insulation material, rock wool, and glass wool. When the high-efficiency insulation layer 12 includes multiple of the following: polyurethane foam, polyurethane insulation board, EPS polystyrene board, XPS extruded polystyrene board, vacuum insulation board, graphite EPS polystyrene board, graphite XPS extruded polystyrene board, aerogel insulation material, rock wool, and glass wool, these multiple materials are stacked on top of each other to achieve a high-efficiency insulation effect.

[0072] The connecting tie rod 2 includes a connecting rod 21 and four limiting plates 22. The connecting rod 21 passes through the inner self-insulating wall panel 13, the high-efficiency insulation layer 12, and the outer self-insulating wall panel 11. The four limiting plates 22 abut against the two sides of the inner self-insulating wall panel 13, the high-efficiency insulation layer 12, and the outer self-insulating wall panel 11, respectively. By setting the four limiting plates 22 on the sides of each layer, the connection between the inner self-insulating wall panel 13, the high-efficiency insulation layer 12, and the outer self-insulating wall panel 11 becomes more stable and reliable.

[0073] Specifically, one end of the connecting rod 21 is connected to a limiting plate 22 at the outermost edge, and the other end of the connecting rod 21 is further connected to a limiting plate 22 after passing through each layer, so that the structure is clamped and fixed between the two limiting plates 22. After passing through the last layer, it is connected to the connecting rod 21 by a nut, thereby realizing the connection tie 2 clamping and fixing the inner self-insulating wall panel 13, the high-efficiency insulation layer 12 and the outer self-insulating wall panel 11. The overall structure is simple and very convenient to use.

[0074] In this embodiment, a reinforcing rib component 14 is provided within the inner self-insulating wall panel 13. During the prefabrication of the inner self-insulating wall panel 13 in the factory, the reinforcing rib component 14 is pre-embedded within it. By providing the reinforcing rib component 14 within the inner self-insulating wall panel 13, the overall bending and flexural resistance of the high-strength self-insulating prefabricated wall panel structure is improved. Of course, in other embodiments, the high-efficiency insulation layer 12 and / or the outer self-insulating wall panel 11 may also be provided with reinforcing rib components 14, further improving the overall bending and flexural resistance of the high-efficiency self-insulating composite wall panel structure.

[0075] The reinforcing rib component 14 can be made of metal, which ensures its reinforcing effect. Alternatively, the reinforcing rib component 14 can be made of fiber-reinforced composite materials, such as FRP (Fiber Reinforced Polymer / Plastic), which effectively improves the stability of the high-strength self-insulating prefabricated wall panel structure and avoids thermal bridging.

[0076] The number of reinforcing rib components 14 can be one or more, and the specific number is not limited. The shape of the reinforcing rib component 14 can be strip-shaped, mesh-shaped, or cage-shaped. The strip-shaped reinforcing rib component 14 can be a reinforcing rib and a keel; the mesh-shaped form can be wire mesh, reinforcing mesh sheet, or keel frame; and the cage-shaped form can be a reinforcing mesh cage. Specifically, the reinforcing rib component 14 can be a reinforcing mesh sheet composed of vertical and horizontal reinforcing ribs. The reinforcing rib component 14 can also be a reinforcing mesh cage composed of vertical, horizontal, and vertical or diagonal reinforcing ribs. The reinforcing rib component 14 can also be an L-shaped, C-shaped, I-shaped, or hollow tube keel. The hollow tube is pre-embedded in the inner self-insulating wall panel 13, the high-efficiency insulation layer 12, and / or the outer self-insulating wall panel 11, and the internal space of the hollow tube can be used for the passage of electrical wires and cables. The hollow tube can be a hollow square tube.

[0077] In this embodiment, the plane of the reinforcing rib component 14 is parallel to the side surface of the inner self-insulating wall panel 13. The inner self-insulating wall panel 13 is plate-shaped, and the reinforcing rib component 14 is embedded in the inner self-insulating wall panel 13. The reinforcing rib component 14 extends outward along the plane of the inner self-insulating wall panel 13, and the reinforcing rib component 14 does not protrude from the inner self-insulating wall panel 13.

[0078] During construction and installation, the reinforcing rib component 14, in conjunction with the wall tie component 20, further enhances the safety of the high-strength self-insulating prefabricated wall panel structure after it is installed on the wall, preventing it from falling or detaching. The wall tie component 20 and the reinforcing rib component 14 can be anchored or welded together, further enhancing the reliability of the connection between the high-strength self-insulating prefabricated wall panel structure and the main building frame 10 via the wall tie component 20, significantly improving the safety and stability of the energy-saving wall structure.

[0079] The high-strength self-insulating prefabricated wall panel structure is manufactured in a factory and then transported to the site for installation. In this embodiment, the upper and lower end faces or four end faces of the wall panel body 1 are provided with tongue and groove joints 18. In use, multiple high-strength self-insulating prefabricated wall panel structures are connected to the main building frame 10 and spliced ​​together. The tongue and groove joints 18 enhance the waterproof effect at the joints between wall panel bodies 1, preventing rainwater from seeping through the joints.

[0080] High-strength self-insulating prefabricated wall panel structures can be used as external wall panels in energy-saving wall structures. In this embodiment, part of the wall panel body 1 is attached to and abuts against the outer side of the building frame body 10, and the remaining structure of the wall panel body 1 extends into the building frame body 10. Specifically, the high-efficiency insulation layer 12 and the inner self-insulating wall panel 13 in the wall panel body 1 extend into the building frame body 10, and the outer self-insulating wall panel 11 in the wall panel body 1 is attached to and abuts against the outer side of the building frame body 10. The outer self-insulating wall panels 11 of two adjacent wall panel bodies 1 are spliced ​​together and located on the outer side of the building frame body 10, realizing a semi-enclosed form of external wall panels. The panel joints are located on the outer side of the building frame body 10, effectively preventing rainwater from seeping through the panel joints and further improving the waterproof effect.

[0081] The energy-saving wall structure also includes a finishing layer 30, which is connected to the side of the wall panel body 1. In this embodiment, the finishing layer 30 is connected to the outer side of the wall panel body 1, that is, the finishing layer 30 is connected to the side of the outer self-insulating wall panel 11 facing away from the high-efficiency insulation layer 12. The finishing layer 30 has a strengthening and protective function, ensuring the good functionality of the energy-saving wall structure. The finishing layer 30 includes mortar and a mesh fabric. The mortar is connected to the outer side of the outer self-insulating wall panel 11 facing away from the high-efficiency insulation layer 12, and the mesh fabric is placed within the mortar. The mesh arrangement within the mortar enhances the overall structural strength of the finishing layer 30, and the mortar is used for leveling and protection. Preferably, the mortar is a polymer crack-resistant mortar.

[0082] The energy-saving wall structure also includes a finishing layer 40, which is connected to the side of the plaster layer 30. Specifically, the finishing layer 40 is connected to the outer side of the plaster layer 30, that is, the finishing layer 40 is connected to the side of the plaster layer 30 facing away from the outer side of the self-insulating wall panel 11. The finishing layer 40 is used to protect the wall, beautify the building, and meet usage requirements. The material of the finishing layer 40 can be paint, ceramic tile, stone, metal plate, or UHPC. When the material of the finishing layer 40 is UHPC, a reinforcing mesh structure is added inside the finishing layer 40. The reinforcing mesh structure can effectively enhance the structural strength of the finishing layer 40 and greatly improve the stability of the energy-saving wall structure.

[0083] When leveling is required, a leveling layer can be added between the high-strength self-insulating prefabricated wall panel structure and the plastering layer 30. The energy-saving wall structure may also include a leveling layer, located between the plastering layer 30 and the high-strength self-insulating prefabricated wall panel structure, and connected to both the plastering layer 30 and the outer self-insulating wall panel 11. The leveling layer ensures the smoothing of the outer surface of the outer self-insulating wall panel 11, effectively preventing the high-strength self-insulating prefabricated wall panel structure from falling off, and significantly improving the safety and stability of the energy-saving wall structure.

[0084] Example 2

[0085] As shown in Figure 4, the parts of the energy-saving wall structure in this embodiment 2 that are the same as those in embodiment 1 will not be repeated; only the differences will be explained. In this embodiment 2, both the inner self-insulating wall panel 13 and the outer self-insulating wall panel 11 are provided with reinforcing ribs 14. When the outer self-insulating wall panel 11 and the inner self-insulating wall panel 13 are prefabricated in the factory, the reinforcing ribs 14 are pre-embedded in the outer self-insulating wall panel 11 and the inner self-insulating wall panel 13. By providing reinforcing ribs 14 in the inner self-insulating wall panel 13 and the outer self-insulating wall panel 11, the overall bending and flexural resistance of the high-strength self-insulating prefabricated wall panel structure is further improved.

[0086] In this embodiment 2, the end face of the wall panel body 1 is provided with a tongue and groove structure 18. Two adjacent high-strength self-insulating prefabricated wall panel structures are attached and connected to each other through the tongue and groove structure 18. The tongue and groove structure 18 can enhance the waterproof effect at the connection between the wall panel body 1 and the wall panel body 1, and prevent rainwater from leaking through the board seam.

[0087] The plaster layer 30 and the finishing layer 40 can be constructed on-site and installed on the high-strength self-insulating prefabricated wall panel structure, or they can be prefabricated and integrated into the high-strength self-insulating prefabricated wall panel structure in the factory. In this embodiment 2, the plaster layer 30 is set on both sides of the high-strength self-insulating prefabricated wall panel structure, and then the finishing layer 40 is set on the plaster layer 30 on both sides. The plaster layer 30 and the finishing layer 40 are integrated through factory prefabrication, which can effectively improve the quality of the finishing effect, increase the degree of industrialization and prefabrication, reduce the amount of on-site construction work, and improve the overall construction quality of the building. Among them, the finishing layer 40 can also be directly prefabricated and integrated into one or both sides of the high-strength self-insulating prefabricated wall panel structure in the factory, that is, the finishing layer 40 is connected to the side of the wall panel body 1.

[0088] Example 3

[0089] As shown in Figure 5, the parts of the energy-saving wall structure in Embodiment 3 that are the same as those in Embodiment 1 will not be repeated; only the differences will be explained. In Embodiment 3, the wall panel body 1 also includes an adhesive layer 15. The adhesive layer 15 is located between the high-efficiency insulation layer 12 and the outer self-insulating wall panel 11 and is connected to both the high-efficiency insulation layer 12 and the outer self-insulating wall panel 11. Simultaneously, the adhesive layer 15 is located between the inner self-insulating wall panel 13 and the high-efficiency insulation layer 12 and is connected to both the inner self-insulating wall panel 13 and the high-efficiency insulation layer 12. The adhesive layer 15 has an adhesive function, effectively strengthening the connection strength between the high-efficiency insulation layer 12 and the outer self-insulating wall panel 11, as well as the connection strength between the inner self-insulating wall panel 13 and the high-efficiency insulation layer 12, further improving the stability and reliability of the high-strength self-insulating prefabricated wall panel structure. The adhesive layer 15 includes cement-based materials, polyurethane adhesive, or epoxy adhesive, providing excellent bonding performance.
