Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0026] The present application provides a thermal insulation wall surface to solve the problems mentioned in the related art, that is, the thermal insulation wall has a short service life and high subsequent maintenance costs.

[0027] See also Figure 1 、 Figure 2The thermal insulation wall includes a frame 100 and a structural layer 200. The structural layer 200 is arranged on the frame 100, and the structural layer 200 includes an insulation layer 210, a strength layer 220 and a decorative layer 230. The insulation layer 210 is filled on one side of the frame 100; the strength layer 220 is fixedly arranged on the side of the frame 100 away from the insulation layer 210, and the side of the strength layer 220 away from the insulation layer 210 is flush with the frame 100. The decorative layer 230 includes a first decorative layer 231 and a second decorative layer 232. The first decorative layer 231 is arranged on the strength layer 220 to cover the strength layer 220; the second decorative layer 232 is arranged on the side of the frame 100 away from the strength layer 220 to cover the frame 100 and the insulation layer 210.

[0028] Specifically, the thermal insulation wall of this embodiment is formed by a frame 100 and a structural layer 200. The structural layer 200 further comprises an insulation layer 210, a strength layer 220, and a decorative layer 230. The strength layer 220 is disposed on the frame 100, providing sufficient structural strength for the thermal insulation wall of this embodiment. The thermal insulation layer 210 is disposed on the frame 100 and aligned with the strength layer 220 to ensure the thermal insulation effect of the thermal insulation wall. The first decorative layer 231 is arranged on the strength layer 220, and the side of the first decorative layer 231 away from the frame is flush with the side of the strength layer 220 away from the frame, and can cover and mask the strength layer 220 and the side of the thermal insulation layer 210 arranged close to the strength layer 220. The second decorative layer 232 is arranged on the side of the frame 100 away from the strength layer 220, and can cover and mask the other side of the frame 100 and the thermal insulation layer 210, that is, the first decorative layer 231 and the second decorative layer 232 are respectively arranged at the two ends of the frame 100, covering and masking the frame 100, the thermal insulation layer 210 and the strength layer 220 from both ends of the frame 100.

[0029] In this embodiment, the first decorative layer 231 and the second decorative layer 232 are respectively disposed on two sides of the insulation wall surface, cooperating to completely cover the insulation wall surface. In other words, the insulation wall surface is exposed to the outside world only by the first decorative layer 231 and the second decorative layer 232. This embodiment can select different materials for the first decorative layer 231 and the second decorative layer 232 according to the actual application scenario of the insulation wall surface, thereby reducing the impact of the external environment on the first decorative layer 231 and the second decorative layer 232, extending the service life of the first decorative layer 231 and the second decorative layer 232, protecting other layers within the insulation wall, preventing the performance of the insulation wall from deteriorating, extending the service life of the insulation wall surface, and reducing the subsequent maintenance costs of the insulation wall surface.

[0030] In the prior art, the outer panels of insulation walls are typically made of vertically mounted color-coated steel sheets with a thickness of 0.5mm-0.6mm. Color-coated steel sheets have a service life of approximately 10 years in chemical plants. Because the air inside chemical plants is more corrosive than elsewhere, the long-term effects of natural and man-made environments can cause complex physical and chemical reactions that damage the color-coated steel sheets. Over time, the accumulation of these damages can lead to a gradual deterioration in the performance of the outer panels, resulting in damage to the outer color-coated steel sheets and ultimately widespread water leakage on the insulation walls, which can lead to a loss of both functionality and aesthetics.

[0031] In this embodiment, the outer panels of the insulation wall are a first decorative layer 231 and a second decorative layer 232, and the materials of the first decorative layer 231 and the second decorative layer 232 can be arbitrarily set, so that this embodiment can be applied to any working environment. For example, if it is to be used in a chemical enterprise, the first decorative layer 231 and / or the second decorative layer 232 can be made of aluminum-magnesium-manganese alloy. Aluminum-magnesium-manganese alloy is corrosion-resistant and has self-rust resistance. It can form an oxide layer in the air, effectively preventing metal oxidation and rust. It has good acid and alkali resistance and can be used for more than 30 years in chemical enterprises, greatly extending the service life of the insulation wall of this embodiment. In addition, aluminum-magnesium-manganese alloy has high strength and strong plasticity, which can improve the durability of the insulation wall. Even if the insulation wall is deformed, it only needs to be re-maintained and leveled. Before reaching its service life, there is no need for excessive maintenance and repair of the insulation wall, which reduces maintenance costs.

[0032] In one embodiment, for example, Figure 1 、 Figure 2 As described, a cold bridge assembly 300 is provided between the frame 100 and the first decorative layer 231, and the cold bridge assembly 300 is covered on the frame 100. The cold bridge assembly 300 includes a glass wool layer, and the thickness of the glass wool of the glass wool layer in a fluffy state is L1, satisfying: L1 ≥ 30 mm. A cold bridge refers to a phenomenon in a building envelope structure where heat is more easily transferred through certain paths due to differences in the thermal conductivity of materials. Providing the cold bridge assembly 300 in the first decorative layer 231 can prevent the frame 100 from directly contacting the first decorative layer 231, causing heat on one side of the insulation wall to be transferred along the frame 100 to the first decorative layer 231, and dissipating from the first decorative layer 231 to the outside world, thereby improving the insulation effect of this embodiment.

[0033] The thermal conductivity of glass wool is generally between 0.035W / (m·K) and 0.045W / (m·K), which means that it has a relatively low thermal conductivity. This means that the glass wool has a relatively strong thermal insulation capability. Placing glass wool between the frame 100 and the first decorative layer 231 can prevent the formation of a cold bridge between the frame 100 and the first decorative layer 231, thereby preventing the formation of a cold bridge, which would otherwise affect the thermal insulation effect of this embodiment. It is understandable that increasing the thickness of the glass wool can effectively improve the thermal insulation effect of the glass wool layer, but this will also increase the cost accordingly. In this embodiment, the fluffy glass wool is at least 30mm thick and is compressed and placed between the frame 100 and the first decorative layer 231 to ensure that the glass wool layer blocks the cold bridge, thereby improving the thermal insulation effect of this embodiment.

[0034] In some embodiments, for example, Figure 1 、 Figure 2 As shown, a vapor barrier assembly 400 is provided between the frame 100 and the second decorative layer 232 to separate the frame 100 and the second decorative layer 232. The vapor barrier is an important structural layer in the building wall, which is used to prevent indoor moisture from diffusing to the outdoors through the wall, thereby avoiding problems such as condensation, mold growth and structural damage inside the wall. The vapor barrier is usually located on the inner side of the wall, close to the indoor side, to block the penetration of indoor moisture. In this embodiment, the first decorative layer 231 is used as the outer wall surface, and the second decorative layer 232 is used as the inner wall surface. The vapor barrier assembly 400 is provided between the frame 100 and the second decorative layer 232, which can effectively prevent indoor moisture from affecting the frame 100, improve the reliability of the thermal insulation wall surface of this embodiment, and ensure the service life of the thermal insulation wall surface.

[0035] In one embodiment, for example, Figure 1 、 Figure 2 As shown, the vapor barrier assembly 400 includes an aluminum foil layer, which includes an extension portion 420 and a connecting portion 410. Two extension portions 420 are provided, one on each side of the connecting portion 410, away from the frame 100. The connecting portion 410 overlaps the frame 100, and the end of the extension portion 420 away from the frame 100 overlaps the insulation layer 210. In this embodiment, the aluminum foil layer is used as the vapor barrier assembly 400. Aluminum foil has high reflectivity and vapor barrier properties, effectively preventing indoor moisture from contacting the frame 100, preventing the frame 100 or other layers within the insulated wall from being affected by moisture, leading to mold or performance degradation. Furthermore, the aluminum foil effectively reflects thermal radiation, further enhancing the insulation capacity of the insulated wall.

[0036] The aluminum foil layer includes an extension portion 420 and a connection portion 410. The connection portion 410 is overlapped on the frame 100 to isolate the frame 100 from moisture from the front of the connection between the frame 100 and the second decorative layer 232, thereby protecting the frame 100. The end of the extension portion 420 away from the frame 100 is overlapped on the insulation layer 210, which can isolate the frame 100 from moisture from the side of the connection between the frame 100 and the second decorative layer 232, thereby ensuring the vapor barrier ability of the aluminum foil layer.

[0037] In the related art, a layer of paper-based aluminum foil is usually attached to one side of the insulation layer 210 as a vapor barrier. Paper-based aluminum foil is a composite material, which is made of a thin layer of aluminum foil and a layer of paper-based material combined by adhesive or other methods. It has the advantages of aluminum foil and paper-based materials, but is not resistant to high temperatures. In actual applications, after the wall is installed, if the wall needs to be modified and cut later, since the aluminum foil attachment layer is a paper-based material, it is extremely flammable and does not meet the fire protection requirements of the building. In this embodiment, aluminum foil is directly used as a vapor barrier, which can not only ensure the vapor barrier effect, but also improve the safety of this embodiment. After the insulation wall is installed, the wall can be cut and modified as needed without the risk of flammability.

[0038] In one embodiment, for example, Figure 1 、 Figure 2 As shown, the distance between the end of the extension portion 420 away from the connection portion 410 and the connection portion 410 is L2, satisfying L2 ≥ 150 mm. When indoor moisture penetrates the insulation wall, it can only penetrate from the connection between the frame 100 and the second decorative layer 232. Here, the connection portion 410 of the aluminum foil layer can effectively protect the frame 100. If moisture extends to both sides from the penetration point, the longer the extension distance, the weaker the penetration ability. In this embodiment, the distance of the extension portion 420 is limited to ensure that even if moisture penetrates into the second decorative layer 232 and extends to both sides, it will not penetrate into the frame 100 from the overlap between the extension portion 420 and the insulation layer 210, further ensuring the vapor isolation effect of the vapor isolation component 400.

[0039] In one embodiment, for example, Figure 1 、 Figure 2 As shown, the first decorative layer 231 includes a metal decorative plate, and the first decorative layer 231 is formed by splicing multiple metal decorative plates. The metal decorative plates are configured as aluminum-magnesium-manganese alloy plates. The first decorative layer 231 is configured by splicing multiple metal decorative plates. This ensures the protective capabilities of the first decorative layer 231 while also enhancing its aesthetics.

[0040] The metal decorative plates can be arbitrarily spliced ​​to form the first decorative layer 231. For example, the metal decorative plates can be set as horizontal plates, vertical plates, or other inclined or cross-set plates, as long as the protective effect after splicing is guaranteed.

[0041] In one embodiment, for example, Figure 1 、 Figure 2 As shown, the second decorative layer 232 is configured as a color-coated steel plate with a thickness of L3, satisfying the requirement of L3 ≥ 0.4 mm. The second decorative layer 232 is configured as an interior panel, meaning it is installed indoors, where the overall indoor environment is better than outdoors. Therefore, using a color-coated steel plate as the second decorative layer 232 still provides satisfactory corrosion resistance, ensuring the longevity of the insulation wall while maintaining structural strength and overall aesthetics.

[0042] In one embodiment, for example, Figure 1 、 Figure 2 As shown, the insulation layer 210 is configured as a rock wool board, and the thickness of the rock wool board is L4, satisfying the following conditions: 75mm≤L4≤100mm. Rock wool board is a commonly used insulation material, which is made from natural rocks such as basalt and diabase through processes such as high-temperature melting, centrifugal fiberization, and solidification molding. Rock wool board has good thermal insulation capacity. In this embodiment, using rock wool board as the insulation layer 210 can effectively achieve thermal insulation effect. In addition, rock wool board also has low hygroscopicity, and can maintain a good thermal insulation effect even in a relatively humid environment. Rock wool board is also easy to cut and install, which can reduce the construction difficulty of this embodiment. Limiting the thickness of the rock wool board can ensure that the insulation layer 210 has sufficient thermal insulation capacity.

[0043] In the related art, the insulation layer 210 of the insulation wall usually adopts a bulk density less than 20kg / m 3 Centrifugal ultra-fine glass wool felt is difficult to achieve thermal insulation effect in temperatures below -10℃; in the hot summer, the room is relatively hot, resulting in hot summer and cold winter, which cannot meet the requirements of thermal insulation and energy saving. 3 Because the glass wool felt is not arranged vertically and is too heavy, it can break during installation. Furthermore, the glass wool felt must be fixed between the outer panel and the purlin. The greater the bulk density, the smaller the compression ratio of the glass wool felt at a given thickness, resulting in significant deviations in the flatness of the wall panel installation.

[0044] In this embodiment, rock wool board is used as the insulation layer 210, which has good thermal insulation and heat insulation effects and is easy to cut and install. The rock wool board is combined with the cold bridge assembly 300 and the vapor barrier assembly 400 to further ensure the thermal insulation effect of this embodiment.

[0045] In one embodiment, for example, Figure 1 、 Figure 2 As shown, the frame 100 includes a wall purlin 110, which is configured as a C-shaped steel, and the wall purlin 110 is made of hot-dip galvanized material. The wall purlin 110 is an important component in a building structure, and is mainly used to support the structure of a wall, roof or floor. It is usually used to strengthen the stability of the wall and ensure the safety and durability of the structure. In this embodiment, the C-shaped steel itself has high strength and rigidity, can withstand large loads in the vertical and horizontal directions, and performs well when bearing loads, and can provide stable support. Hot-dip galvanizing forms a layer of zinc on the surface of the C-shaped steel. This layer of zinc can effectively prevent the steel from coming into contact with oxygen and moisture in the air, thereby preventing corrosion. Due to its strong corrosion resistance, the service life of hot-dip galvanized C-shaped steel is much longer than that of untreated steel, reducing the frequency of maintenance and replacement and reducing long-term costs.

[0046] In this embodiment, hot-dip galvanized C-shaped steel is used as the wall purlin 110, which can ensure the structural strength of the thermal insulation wall of this embodiment and generally extend the service life of the thermal insulation wall.

[0047] The present application also provides an industrial plant, which uses the thermal insulation wall surface of any one of the above embodiments as a wall.

[0048] An industrial plant having the thermal insulation wall of any one of the above embodiments also has all the above beneficial effects of the thermal insulation wall, which will not be described in detail here.

[0049] It should be noted that, unless there is any conflict, the features in the embodiments of this application can be combined with each other.

[0050] The foregoing description is merely a preferred embodiment of the present application and is not intended to limit the present application. Persons skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
