Description

High-efficiency self-insulating modular 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-efficiency self-insulating modular 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 (typically around 0.14–0.16 W / (m·K)), the overall thickness of the wall panels is often excessive 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. Therefore, a new wall panel construction system is urgently needed to simultaneously meet the requirements of prefabricated construction, building energy conservation, and safety and reliability.

[0061] 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.

[0062] Example 1

[0063] As shown in Figures 1, 2, and 3, this embodiment discloses an energy-saving wall structure, which includes a high-efficiency self-insulating modular wall panel structure. The high-efficiency self-insulating modular 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 inner self-insulating wall panel 13, the high-efficiency insulation layer 12, and the outer self-insulating wall panel 11 and abut against the opposite sides of the inner and outer self-insulating wall panels 13 and 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 by several connecting fasteners 2 to form a multi-layer structure. 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 several connecting tie pieces 2, which effectively prevents falling and greatly improves the safety and stability of the high-efficiency self-insulating modular wall panel structure.

[0064] 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 or polyurethane materials. The organic material in the organic-inorganic composite insulation material is expandable polystyrene particles. The volume water absorption rate of the materials of the inner self-insulating wall panel 13 and the outer self-insulating wall panel 11 is ≤15%. The fire rating of the inner self-insulating wall panel 13 and the outer self-insulating wall panel 11 is A2 or higher. The compressive strength of the outer self-insulating wall panel 11 is 0.30MPa or higher and the thickness of the outer self-insulating wall panel 11 is 50mm or higher. The compressive strength of the inner self-insulating wall panel 13 is 3.5MPa or higher. The outer self-insulating wall panel 11 is constructed using fire-resistant insulation material with a fire rating of A2 or higher, a compressive strength of 0.30 MPa or higher, and a thickness of 50 mm or more. This ensures that the wall panel strength meets relevant application requirements while also providing fire resistance and insulation. The inner self-insulating wall panel 13 has a compressive strength of 3.5 MPa or higher, providing reliable material strength support for its application as an exterior wall cladding. Both the inner and outer self-insulating wall panels 13 and 11 have a volumetric water absorption rate of ≤15%, effectively preventing water leakage and ensuring the long-term effectiveness of the insulation in the high-efficiency self-insulating modular wall panel structure. The high-efficiency insulation layer 12 has a higher thermal conductivity than both the inner and outer self-insulating wall panels 13 and 11, significantly improving insulation performance and optimizing the overall insulation effect of the high-efficiency self-insulating modular wall panel structure. This achieves fire safety, flame retardancy, and excellent insulation performance in the high-efficiency self-insulating modular wall panel structure.

[0065] The energy-saving wall structure also includes a main building structure 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 main building structure 10 and the wall panel body 1. The top and bottom of the high-efficiency self-insulating modular wall panel structure are installed and connected to the main building structure 10 through several wall-connecting components 20, so as to achieve reliable and convenient installation.

[0066] In this embodiment, both the inner self-insulating wall panel 13 and the outer self-insulating wall panel 11 are provided with reinforcing ribs 14. During the prefabrication of the inner and outer self-insulating wall panels 13 and 11 in the factory, the reinforcing ribs 14 are pre-embedded within them. By providing reinforcing ribs 14 within the inner and outer self-insulating wall panels 13 and 11, the overall bending and flexural strength of the high-strength self-insulating prefabricated wall panel structure is improved. Of course, in other embodiments, reinforcing ribs 14 can also be provided within the high-efficiency insulation layer 12 to further improve the overall bending and flexural strength of the high-efficiency self-insulating prefabricated wall panel structure.

[0067] 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-efficiency self-insulating modular wall panel structure and avoids thermal bridging.

[0068] 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.

[0069] In this embodiment, the plane of the reinforcing rib component 14 is parallel to the side surfaces of the inner self-insulating wall panel 13 and the outer self-insulating wall panel 11. The inner self-insulating wall panel 13 and the outer self-insulating wall panel 11 are plate-shaped. The reinforcing rib component 14 is embedded in the outer self-insulating wall panel 11 and / or the inner self-insulating wall panel 13. The reinforcing rib component 14 extends outwards along the plane direction of the inner self-insulating wall panel 13 and the outer self-insulating wall panel 11, and the reinforcing rib component 14 is not exposed in the inner self-insulating wall panel 13 and the outer self-insulating wall panel 11.

[0070] During construction and installation, the reinforcing rib component 14, in conjunction with the wall tie component 20, further enhances the safety of the high-efficiency 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-efficiency self-insulating prefabricated wall panel structure and the main building structure 10 via the wall tie component 20, thus significantly improving the safety and stability of the high-efficiency self-insulating prefabricated wall panel structure.

[0071] In this embodiment, the thermal conductivity of the outer self-insulating wall panel 11 is below 0.060 W / (m·K). While ensuring the insulation effect of the material, it can effectively optimize the overall heat transfer coefficient of the high-efficiency self-insulating modular wall panel structure, thereby optimizing the energy-saving insulation effect of the energy-saving wall structure.

[0072] 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 improving material strength and thickness. Simultaneously, it increases the structural reliability of the high-efficiency self-insulating modular wall panel structure itself and the reliability of the connection between the high-efficiency self-insulating modular wall panel structure and the main building structure 10.

[0073] 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.

[0074] 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-efficiency self-insulating modular wall panel structure and greatly improves the safety and stability of the high-efficiency self-insulating modular wall panel structure.

[0075] 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.

[0076] The connecting tie element 2 includes a connecting rod 21 and four limiting discs 22. The connecting rod 21 passes through the inner self-insulating wall panel 13, the reinforcing rib component 14, the high-efficiency insulation layer 12, and the outer self-insulating wall panel 11. The four limiting discs 22 respectively 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. By setting the four limiting discs 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.

[0077] 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.

[0078] The high-efficiency self-insulating modular 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-efficiency self-insulating modular wall panels are connected to the main building structure 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.

[0079] The high-efficiency self-insulating modular wall panel structure can be applied to energy-saving wall structures using external wall panels. In this embodiment, the inner side of the wall panel body 1 has a tongue-and-groove structure 18, and the main building structure 10 is embedded in the tongue-and-groove structure 18. Specifically, the tongue-and-groove structure 18 is provided at the top and / or bottom of the inner side of the wall panel body 1, so that a groove is formed between two adjacent wall panel bodies 1. The main building structure 10 is embedded in the groove formed by the tongue-and-groove structure 18, and part of the structure of the two adjacent wall panel bodies 1 is located on the outer side of the main building structure 10, realizing a semi-enclosed form of the external wall panel. The panel joint is located at the outer side of the main building structure 10, effectively preventing rainwater from seeping through the panel joint and further improving the waterproof effect.

[0080] 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.

[0081] 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.

[0082] When leveling is required, a leveling layer can be added between the high-efficiency 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-efficiency 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-efficiency self-insulating prefabricated wall panel structure from falling off, and greatly improving the safety and stability of the energy-saving wall structure.

[0083] Example 2

[0084] As shown in Figure 4, the parts of the energy-saving wall structure in Embodiment 2 that are the same as those in Embodiment 1 will not be repeated; only the differences will be explained. In Embodiment 2, 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-efficiency self-insulating modular wall panel structure. The adhesive layer 15 includes cement-based materials, polyurethane adhesive, or epoxy adhesive, providing excellent bonding performance.

[0085] An interface agent layer 16 may be provided on the side of the inner self-insulating wall panel 13 facing the high-efficiency insulation layer 12, so that the interface agent layer 16 connects the inner self-insulating wall panel 13 and the adhesive layer 15; an interface agent layer 16 may also be provided on the side of the outer self-insulating wall panel 11 facing the high-efficiency insulation layer 12, so that the interface agent layer 16 connects the outer self-insulating wall panel 11 and the adhesive layer 15. The interface agent layer 16 can enhance the adhesion between the inner self-insulating wall panel 13 and the adhesive layer 15 and / or between the outer self-insulating wall panel 11 and the adhesive layer 15, further strengthening the overall structural connection strength of the high-efficiency self-insulating modular wall panel structure, effectively preventing the high-efficiency self-insulating modular wall panel structure from falling, and greatly improving the safety and reliability of the energy-saving wall structure.

[0086] Both sides of the high-efficiency insulation layer 12 are provided with inwardly recessed connecting grooves 121. The connecting grooves 121 effectively increase the connection area, allowing the adhesive layer 15 to flow into the connecting grooves 121 to strengthen the connection between the high-efficiency insulation layer 12 and the outer self-insulating wall panel 11 and the inner self-insulating wall panel 13. This further strengthens the overall structural connection strength of the high-efficiency self-insulating modular wall panel structure, effectively preventing the high-efficiency self-insulating modular wall panel structure from falling off, and greatly improving the safety and reliability of the energy-saving wall structure. Of course, in other embodiments, the inwardly recessed connecting grooves 121 can also be provided on either side of the high-efficiency insulation layer 12.

[0087] In this embodiment 2, the wall panel body 1 also includes an outer protective layer 17, which is connected to the opposite sides of the inner self-insulating wall panel 13 and the outer self-insulating wall panel 11. The high-efficiency self-insulating modular wall panel structure is manufactured in the factory. By setting the outer protective layer 17 on both sides of the wall panel body 1, the outer protective layer 17 has a protective function, which can further improve the impact resistance of the high-efficiency self-insulating modular wall panel structure, effectively avoiding damage to the high-efficiency self-insulating modular wall panel structure during transportation and use, and ensuring high safety and reliability.

[0090] 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 high-efficiency self-insulating prefabricated wall panel structure is installed within the main building structure 10, such that the upper and lower high-efficiency self-insulating prefabricated wall panel structures are located at the upper and lower ends of the floor slab of the main building structure 10, respectively. Specifically, the upper and lower wall panel bodies 1 are respectively connected to the upper and lower ends of the main building structure 10, so that the outer surface of the main building structure 10 is flush with the outer surface of the upper and lower wall panel bodies 1.

[0091] After the high-efficiency self-insulating prefabricated wall panel structure is installed, a plastering layer 30 and a finishing layer 40 are applied to the outer surfaces of the high-efficiency self-insulating prefabricated wall panel structure and the main building structure 10.

[0093] As shown in Figure 6, the parts of the energy-saving wall structure in Embodiment 4 that are the same as those in Embodiment 2 will not be repeated; only the differences will be explained.

The connecting groove 121 is provided on the outer self-insulating wall panel 11 and / or the inner self-insulating wall panel 13, so that the adhesive layer 15 and the interface agent layer 16 are located within the connecting groove 121 to increase the connection area, further strengthening the overall structural connection strength of the high-efficiency self-insulating modular wall panel structure, effectively preventing the high-efficiency self-insulating modular wall panel structure from falling, and greatly improving the safety and reliability of the energy-saving wall structure.

[0094] Example 5

[0095] As shown in Figure 7, the parts of the energy-saving wall structure in this embodiment 5 that are the same as those in embodiment 1 will not be repeated; only the differences will be explained. In this embodiment 5, the upper and lower end faces or the four end faces of the wall panel body 1 are provided with tongue and groove structures 18. Two adjacent high-efficiency self-insulating modular wall panel structures are connected to each other through the tongue and groove structures 18. The tongue and groove structures 18 can enhance the waterproof effect at the connection between the wall panel bodies 1 and prevent rainwater from seeping through the joints.

[0096] The plaster layer 30 and the finishing layer 40 can be constructed on-site and installed on the high-efficiency self-insulating modular wall panel structure, or they can be prefabricated and integrated into the high-efficiency self-insulating modular wall panel structure in the factory. In this embodiment 5, the plaster layer 30 is set on both sides of the high-efficiency self-insulating modular 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-efficiency self-insulating modular wall panel structure in the factory, that is, the finishing layer 40 is connected to the side of the wall panel body 1.

[0098] As shown in Figure 8, the parts of the energy-saving wall structure in this embodiment 6 that are the same as those in embodiment 1 will not be repeated; only the differences will be explained. In this embodiment 6, the outer side of the main building structure 10 is attached to and abuts against the inner side of the wall panel body 1. That is, multiple high-efficiency self-insulating modular wall panel structures are all set on the outer side of the main building structure 10, realizing a full-coverage form of external wall panels.

[0099] Among them, the inner side of the wall panel body 1 has a tongue and groove structure 18, and the tongue and groove structure 18 of two adjacent high-efficiency self-insulating combined prefabricated wall panel structures corresponds to the outer side of the floor slab of the main building structure 10, which effectively prevents rainwater from seeping through the board joints and further improves the waterproof effect.
