Description

[0002] With increasingly stringent requirements for building energy conservation, building insulation technology plays a crucial role in modern construction projects. However, currently common building insulation materials and systems still have many problems. For example, some organic insulation materials, such as polyurethane foam (PUR) insulation boards, while having excellent insulation performance, have poor fire resistance and produce large amounts of dense smoke and toxic gases when exposed to fire, making them unsuitable for interior building insulation. Inorganic insulation materials, such as rock wool boards and foamed cement boards, while having good fire resistance, suffer from high water absorption and insufficient strength, affecting their insulation effect and service life.

[0003] Furthermore, traditional composite insulation boards pose safety hazards during construction due to insecure installation and easy detachment. For example, XPS extruded polystyrene boards do not bond firmly to plaster mortar and are prone to falling off. Additionally, existing insulation systems suffer from insufficient connection strength between the insulation layer and the base wall, leading to separation of the insulation layer from the wall, affecting insulation performance and overall building performance, thus compromising both safety and energy efficiency.

[0004] In summary, existing building insulation technologies still have shortcomings in terms of fire resistance, durability, ease of construction, and insulation effect, and a new technical solution is needed to overcome these problems. Summary of the Invention

[0052] 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.

[0053] Example 1

[0054] This embodiment discloses an insulated wall structure, which includes a high-efficiency and safe composite insulation device. As shown in Figures 1 and 2, the high-efficiency and safe composite insulation device includes an energy-saving outer protective panel 1, an inner insulation layer 2, and an adhesive layer 3. The adhesive layer 3 is located between the energy-saving outer protective panel 1 and the inner insulation layer 2 and is connected to both. The compressive strength of the energy-saving outer protective panel 1 reaches 0.3 MPa or higher, the fire resistance rating of the energy-saving outer protective panel 1 reaches A2 or higher, the thickness of the energy-saving outer protective panel 1 is not less than 50 mm, and the energy-saving outer protective panel 1 is an A-class fire-resistant organic-inorganic composite material. The inner insulation layer 2 is a high-efficiency insulation material with a lower thermal conductivity than the insulation material constituting the energy-saving outer protective panel 1. The high-efficiency and safe composite insulation device also includes at least one reinforcing mesh component 4, which is placed inside and / or on the side of the energy-saving outer protective panel 1.

[0055] The energy-saving exterior cladding panel 1 uses Class A fire-resistant organic-inorganic composite materials (material combustion rating not lower than A2 and thickness ≥50mm), which can effectively protect the inner insulation layer 2 material from fire. The thickness ≥50mm meets the relevant fire protection design requirements, fundamentally eliminating fire hazards to materials and buildings. Its compressive strength ≥0.3MPa fully meets the impact resistance requirements of the building's exterior wall system, ensuring the long-term durability and safety of the exterior wall system. The reinforcing mesh component 4 in the energy-saving exterior cladding panel 1, together with the anchoring connector that passes through it and connects to the concrete pouring during construction, provides reliable anti-fall and anti-detachment structural measures for the exterior wall system, overcoming the problems of insulation / cladding layer detachment and falling that exist in traditional exterior wall systems.

[0056] The highly efficient and safe composite insulation device utilizes an energy-saving outer cladding panel 1 made of Class A fire-resistant organic-inorganic composite material, which effectively provides fire protection and is lightweight. The inner insulation layer 2, made of a high-efficiency insulation material with a lower thermal conductivity than the insulation material constituting the outer cladding panel 1, significantly improves insulation performance. This results in a highly efficient and safe composite insulation device that is fire-resistant, flame-retardant, and provides excellent insulation. An adhesive layer 3 connects the outer cladding panel 1 and the inner insulation layer 2, further strengthening the overall structural strength of the highly efficient and safe composite insulation device. This effectively prevents the device from falling, greatly improving the safety and stability of the insulation wall structure and enhancing its fire resistance, durability, ease of construction, and insulation performance.

[0057] The adhesive layer includes cement-based materials, polyurethane adhesive, or epoxy adhesive, providing excellent bonding results.

[0058] The energy-saving outer cladding panel 1 is composed of organic-inorganic composite insulation materials, with the inorganic material in the energy-saving outer cladding panel 1 encasing the organic material within it. By encasing the organic material with high-strength inorganic material, it ensures 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 composite panels to enhance its strength and fire resistance.

[0059] Preferably, the energy-saving outer protective panel 1 is made of graphene insulation material, that is, the material of the energy-saving outer protective panel 1 is graphene insulation material. This effectively ensures the insulation and fire resistance performance of the high-efficiency and safe composite insulation device, and greatly improves the safety and stability of the high-efficiency and safe composite insulation device.

[0060] The high-efficiency insulation material of the inner insulation layer 2 includes one or more of the following: polyurethane insulation material, EPS polystyrene board, XPS extruded polystyrene board, vacuum insulation board, graphite EPS polystyrene board, graphite XPS extruded polystyrene board, and aerogel insulation material. When the high-efficiency insulation material of the inner insulation layer 2 includes multiple of the following, they are stacked on top of each other. Preferably, the thermal conductivity of the inner insulation layer 2 is less than or equal to 0.05 W / m·K, and the fire rating of the inner insulation layer 2 is not lower than B2.

[0061] The high-efficiency and safe composite insulation device also includes an interface agent layer. This interface agent layer can be connected between the inner insulation layer 2 and the adhesive layer 3, or between the energy-saving outer protective panel 1 and the adhesive layer 3. The interface agent layer enhances the adhesion between the inner insulation layer 2 and the adhesive layer 3, and / or between the energy-saving outer protective panel 1 and the adhesive layer 3, further strengthening the overall structural connection of the high-efficiency and safe composite insulation device. This effectively prevents the high-efficiency and safe composite insulation device from falling, greatly improving the safety and stability of the insulation wall structure.

[0062] Example 2

[0063] As shown in Figure 3, the same parts of the high-efficiency and safe composite insulation device in Embodiment 2 as in Embodiment 1 will not be repeated; only the differences will be explained. In Embodiment 2, one side of the inner insulation layer 2 has an inwardly recessed connecting groove 21. The connecting groove 21 is located on the outer side of the inner insulation layer 2 facing the energy-saving outer protective panel 1, allowing the adhesive layer 3 to flow into the connecting groove 21 to strengthen the connection with the inner insulation layer 2. This further strengthens the overall structural strength of the high-efficiency and safe composite insulation device, effectively preventing the device from falling and greatly improving the safety and stability of the insulation wall structure. Of course, in other embodiments, the connecting groove 21 can also be located on the inner side of the inner insulation layer 2 facing away from the energy-saving outer protective panel 1. The connecting groove 21 can increase the connection area and connection strength of the inner side of the inner insulation layer 2, resulting in higher stability.

[0064] Example 3

[0065] As shown in Figures 4 and 5, the same parts of the thermal insulation wall structure in Embodiment 3 as in Embodiment 2 will not be repeated; only the differences will be explained. In Embodiment 3, the high-efficiency and safe composite thermal insulation device also includes at least one reinforcing mesh component 4, which is placed inside the energy-saving outer protective panel 1. The reinforcing mesh component 4 is pre-embedded within the energy-saving outer protective panel 1 during factory prefabrication. The reinforcing mesh component 4 enhances the strength of the energy-saving outer protective panel 1 and the overall strength of the high-efficiency and safe composite thermal insulation device, achieving a strength enhancement effect and greatly improving its stability. Furthermore, the structure is simple and easy to manufacture. During construction and installation, the reinforcing mesh component 4, in conjunction with connecting anchors, further enhances the anti-fall and anti-detachment safety of the high-efficiency and safe composite thermal insulation device after it is installed on the wall.

[0066] In this embodiment 3, the plane of the reinforcing mesh component 4 is parallel to the side of the energy-saving outer protective plate 1. The energy-saving outer protective plate 1 is plate-shaped, and the reinforcing mesh component 4 is embedded in the energy-saving outer protective plate 1. The reinforcing mesh component 4 extends outwards along the plane of the energy-saving outer protective plate 1, and does not protrude from the two sides of the energy-saving outer protective plate 1 and is parallel to the two sides. This allows the reinforcing mesh component 4 to be stably installed in the energy-saving outer protective plate 1 and play a reinforcing role, effectively enhancing the structural stability of the high-efficiency and safe composite insulation device.

[0067] The reinforcing mesh component 4 can be made of metal, which ensures its reinforcing effect. Preferably, the reinforcing mesh component 4 can be treated for rust and corrosion prevention to prevent it from corroding during use and thus affecting its bonding strength with the energy-saving outer protective plate 1. The reinforcing mesh component 4 can also be made of FRP, that is, it can be made of high-strength thermal insulation materials such as fiber-reinforced polymer / plastic (FRP), which effectively improves the stability of the efficient and safe composite insulation device; at the same time, it avoids thermal bridging.

[0068] In this embodiment 3, the efficient and safe composite insulation device can be applied to the insulation wall structure using a non-removable insulation template or an integrated insulation prefabricated component.

[0069] The thermal insulation wall structure also includes a base wall 10. The high-efficiency and safe composite insulation device can utilize a non-removable insulation template, allowing the inner side of the inner insulation layer 2 facing away from the energy-saving outer protective panel 1 to connect to the outer side of the base wall 10. Specifically, the base wall 10 includes a wall reinforcement cage 101 and cast-in-place concrete. The high-efficiency and safe composite insulation device, acting as a non-removable insulation template, is erected on the outer side of the wall reinforcement cage 101, while an inner template is erected on the inner side of the wall reinforcement cage 101. Then, cast-in-place concrete is poured between the high-efficiency and safe composite insulation device and the inner template, so that the cast-in-place concrete covers the wall reinforcement cage 101 to form the base wall 10, thus realizing the application of a non-removable insulation template for the high-efficiency and safe composite insulation device.

[0070] High-efficiency and safe composite insulation devices can also be applied using integrated insulation prefabricated components, so that the inner side of the inner insulation layer 2 facing away from the energy-saving outer cladding 1 is connected to the outer side of the base wall 10. Specifically, the components are integrated and processed in the factory so that the inner side of the high-efficiency and safe composite insulation device is connected to the outer side of the base wall 10, and then transported to the site for direct installation without the need for on-site concrete pouring, thereby realizing the application of integrated insulation prefabricated components.

[0071] Example 4

[0072] As shown in Figure 6, the same parts of the thermal insulation wall structure in Embodiment 4 as in Embodiment 3 will not be repeated; only the differences will be explained. In Embodiment 4, the high-efficiency and safe composite thermal insulation device also includes a connecting reinforcement layer 5, which is connected to the inner side of the inner insulation layer 2 facing away from the energy-saving outer protective panel 1. The connecting reinforcement layer 5 strengthens the bond strength between the inner insulation layer 2 and the base wall 10, thereby effectively preventing the high-efficiency and safe composite thermal insulation device from falling and greatly improving the safety and stability of the thermal insulation wall structure. The connecting reinforcement layer 5 is composed of cement-based materials and / or an interface agent.

[0073] Example 5

[0074] As shown in Figure 7, the same parts of the thermal insulation wall structure in Embodiment 5 as in Embodiment 3 will not be repeated; only the differences will be explained. In Embodiment 5, the high-efficiency and safe composite thermal insulation device uses a double-mold shell component in the thermal insulation wall structure. The thermal insulation wall structure includes a base wall 10 and an inner mold shell 50. The base wall 10 includes a wall reinforcement cage 101 and cast-in-place concrete. The wall reinforcement cage 101 is located between the inner mold shell 50 and the high-efficiency and safe composite thermal insulation device, forming a double-mold shell component. The cast-in-place concrete is poured between the inner mold shell 50 and the high-efficiency and safe composite thermal insulation device and forms the base wall 10 with the wall reinforcement cage 101, so that the inner and outer sides of the base wall 10 are respectively connected to the inner mold shell 50 and the inner insulation layer 2, thereby realizing the application of the high-efficiency and safe composite thermal insulation device using a double-mold shell component.

[0075] Example 6

[0076] As shown in Figure 8, the same parts of the thermal insulation wall structure in Embodiment 6 as in Embodiment 3 will not be repeated; only the differences will be explained. In Embodiment 6, the high-efficiency and safe composite thermal insulation device uses an external wall panel in the thermal insulation wall structure. First, the high-efficiency and safe composite thermal insulation device is connected to the load-bearing structure of the building's outer frame. Then, a base wall 10 is fabricated on the inner side of the high-efficiency and safe composite thermal insulation device so that the base wall 10 is connected to the inner insulation layer 2 of the high-efficiency and safe composite thermal insulation device, thereby realizing the application of the high-efficiency and safe composite thermal insulation device using an external wall panel. The base wall 10 can be composed of concrete or concrete combined with reinforcing mesh / reinforcement; if it is composed of concrete combined with reinforcing mesh / reinforcement, the reinforcing mesh or reinforcing reinforcement is placed within the concrete.

[0077] Example 7

[0078] As shown in Figure 9, the same parts of the thermal insulation wall structure in Embodiment 7 as in Embodiment 6 will not be repeated; only the differences will be explained. In Embodiment 7, the high-efficiency and safe composite thermal insulation device also uses an external wall panel in the thermal insulation wall structure. The thermal insulation wall structure also includes a reinforcing facing structure 30. The high-efficiency and safe composite thermal insulation device uses an external wall panel so that the reinforcing facing structure 30 is connected to the inner side of the inner insulation layer 2 facing away from the energy-saving outer cladding 1. Specifically, the high-efficiency and safe composite thermal insulation device is first connected to the load-bearing structure of the building's outer frame, and then the reinforcing facing structure 30 is connected to the inner side of the high-efficiency and safe composite thermal insulation device, thereby realizing the application of an external wall panel for the high-efficiency and safe composite thermal insulation device. The reinforcing facing structure 30 can be composed of high-strength mortar and reinforcing mesh / ribs.

[0079] In this embodiment 7, the thermal insulation wall structure also includes a finishing layer 20, which is connected to the outer side of the insulation layer 2 facing away from the inner side of the energy-saving outer protective panel 1. The finishing layer 20 has a reinforcing protective function, ensuring the good functionality of the thermal insulation wall structure. The finishing layer 20 includes mortar and a mesh fabric. The mortar is connected to the outer side of the insulation layer 2 facing away from the inner side of the energy-saving outer protective panel 1, and the mesh fabric is disposed within the mortar. The mesh arrangement within the mortar enhances the overall structural strength of the finishing layer 20, and the mortar is used for leveling and protection. Preferably, the mortar is a polymer crack-resistant mortar.

[0080] The thermal insulation wall structure also includes a finishing layer, which can be attached to the outer side of the plaster layer 20, or directly attached to the outer side of the insulation layer 2 facing away from the inner side of the energy-saving outer cladding panel 1. The finishing layer protects the wall, beautifies the building, and meets usage requirements. The material of the finishing layer can be paint, ceramic tile, stone, metal plate, or UHPC. When the finishing layer is made of UHPC, a reinforcing mesh structure is added within the finishing layer. This reinforcing mesh structure effectively strengthens the structural strength of the finishing layer, greatly improving the stability of the thermal insulation wall structure.

[0081] When leveling is required, a leveling layer can be added between the high-efficiency and safe composite insulation device and the plastering layer 20. The insulated wall structure may also include a leveling layer, located between the plastering layer 20 and the high-efficiency and safe composite insulation device, and connected to both the plastering layer 20 and the energy-saving outer protective panel 1. The leveling layer ensures the smoothing of the outer surface of the energy-saving outer protective panel 1, effectively preventing the high-efficiency and safe composite insulation device from falling off, and greatly improving the safety and stability of the insulated wall structure.

[0086] Of course, in other embodiments, the efficient and safe composite insulation device is applied to the insulation wall structure using one or more of the following methods: no-removal insulation template, integrated insulation prefabricated components, double-shell components, external wall panels, or the same construction method.

[0087] Example 10

[0088] As shown in Figure 12, the parts of the high-efficiency and safe composite insulation device in this embodiment 10 that are the same as those in embodiment 8 will not be repeated; only the differences will be explained. In this embodiment 10, the high-efficiency and safe composite insulation device also includes at least one reinforcing mesh component 4, which is placed on the side of the energy-saving outer protective panel 1. Placing the reinforcing mesh component 4 on the side of the energy-saving outer protective panel 1 eliminates the need to pre-embed the reinforcing mesh component 4 during the fabrication of the energy-saving outer protective panel 1, making assembly between the reinforcing mesh component 4 and the energy-saving outer protective panel 1 very convenient and efficient. Simultaneously, by placing the reinforcing mesh component 4 on the side of the energy-saving outer protective panel 1, the strength of the energy-saving outer protective panel 1 and the overall strength of the high-efficiency and safe composite insulation device can be enhanced, achieving a strength enhancement effect on the high-efficiency and safe composite insulation device and greatly improving its stability; moreover, the structure is simple and easy to manufacture. Furthermore, during construction and installation, the reinforcing mesh component 4, in conjunction with the connecting anchoring connectors, will further improve the anti-fall and anti-detachment safety of the high-efficiency and safe composite insulation device after it is installed on the wall.
