[0002] This application claims the benefit of priority to Korean Patent Application No. 10-2024-0012381, filed on January 26, 2024, and Korean Patent Application No. 10-2024-0055901, filed on April 26, 2024, the entire contents of which are incorporated herein by reference.

[0003] The present invention relates to a composite insulation panel and an insulation system including the composite insulation panel. More specifically, the present invention relates to an insulation system that can ensure high insulation performance and eliminate the risk of fastening component durability by differentially constructing the shapes of the upper and lower insulation panels and forming the lower insulation panel as a single panel by bonding a second portion with an area smaller than the first portion to the first portion. Background Technology

[0004] Liquefying a gas reduces its volume, making it easier to store and transport. Gases in this state are called liquefied gases (LNG). For example, the volume of LNG in its gaseous state is reduced to about 1 / 600th of its gaseous volume, and its liquefaction temperature is about -163°C. Therefore, for the storage and transport of LNG, the internal temperature of the cargo tank should be maintained at cryogenic temperatures. In the case of liquefied hydrogen, since its liquefaction temperature is -235°C, which is lower than that of LNG, the internal temperature of the cargo tank should be maintained at a lower temperature than that required for LNG.

[0005] Therefore, liquefied gas (LNG) carriers may require insulation systems capable of maintaining the internal temperature of the cargo tanks at cryogenic temperatures. When the insulation of the LNG cargo tanks is insufficient, and consequently the LNG storage tanks have high thermal conductivity, the LNG may vaporize, resulting in boil-off gas (BOG). BOG reduces the amount of LNG remaining during transport, which can lead to significant economic losses. Therefore, to reduce BOG and maximize the amount of LNG remaining, insulation materials with excellent insulation properties may be required.

[0006] However, with existing insulation systems, there are practically no other ways to improve insulation performance except by increasing the thickness of the insulation layer. This increase in thickness has the side effect of leading to inefficiencies, such as a reduction in liquefied gas cargo capacity. In particular, because liquefied hydrogen cargo tanks need to maintain a lower temperature environment than LNG cargo tanks, they may require thicker insulation systems than those used for LNG cargo tanks, which could reduce liquefied hydrogen cargo capacity.

[0007] Furthermore, as the thickness of the insulation system increases, the insulation panels inevitably need to be laminated in multiple layers, and such multi-layered insulation systems may require fastening components to secure the insulation panels together. In this case, the fastening components must support the load of the multi-layered insulation panels, and if the durability of the fastening components is not guaranteed, the structural stability of the entire insulation system may be compromised. Summary of the Invention

[0008] Technical issues

[0058] Preferred embodiments of the invention will be described in more detail below with reference to the accompanying drawings.

[0059] Figure 1This is a diagram illustrating a liquefied gas storage tank using an insulation system including a composite insulation panel according to an embodiment of the present invention.

[0060] Figure 1 The liquefied gas storage tank 1 shown can be installed on a ship transporting the gas.

[0061] Reference Figure 1 The liquefied gas storage tank 1 may include an insulation system 100. For example, the liquefaction temperature of the gas (e.g., LNG and liquefied hydrogen) may be a cryogenic temperature at atmospheric pressure, and the insulation system 100 may be applied to the liquefied gas storage tank 1 located on the ship to maintain this cryogenic temperature state. Here, liquefied gas is not limited to LNG and liquefied hydrogen, but may include all gases that are typically stored in a liquid state, such as LPG, ethylene, and ammonia.

[0062] The insulation system 100 may be installed on the inner surface 11 of the liquefied gas storage tank 1. For example, the insulation system 100 may be installed on the inner surface 11 of the liquefied gas storage tank 1 and may be in contact with at least a portion of the liquefied gas stored in the liquefied gas storage tank 1.

[0063] The insulation system 100 can be formed in a laminated form, having a plurality of first composite insulation panels 110 (multilayer composite insulation panels), connecting composite insulation panels 120, and second composite insulation panels 130 (upper composite insulation panels). For example, the first composite insulation panels 110 can be installed on the inner surface 11 of the liquefied gas storage tank 1, the connecting composite insulation panels 120 can be laminated on the upper part of a portion of the first composite insulation panels 110 to connect adjacent first composite insulation panels 110, and the second composite insulation panels 130 can be laminated on the upper parts of the first composite insulation panels 110 and the connecting composite insulation panels 120.

[0064] The shape / structure and lamination structure of the first composite insulation panel 110, the connecting composite insulation panel 120, and the second composite insulation panel 130 constituting the insulation system 100 will be referred to below. Figures 2 to 6 Detailed description.

Figure 6 This is a cross-sectional view showing an insulation system including a composite insulation panel according to an embodiment of the present invention.

[0066] Figure 2This is a perspective view of an insulation system 100 in which multiple composite insulation panels 110, 120 and 130 are laminated. Figure 3 These are a three-dimensional view and an exploded three-dimensional view of the first composite insulation board 110. Figure 4 These are perspective views and exploded perspective views of the composite insulation board 120. Figure 5 These are a three-dimensional view and an exploded three-dimensional view of the second composite insulation board 130. Figure 6 It is shown schematically. Figure 2 A cross-sectional view of the laminated structure of the insulation system 100 shown.

[0067] Reference Figures 2 to 6 According to the embodiment, the insulation system 100 can be configured such that a first composite insulation panel 110, a connecting composite insulation panel 120 and a second composite insulation panel 130 are each arranged in multiple quantities and laminated in an alternating manner.

[0068] According to various embodiments, based on the lamination sequence and position, the first composite insulation panel 110 and the second composite insulation panel 130 can be referred to as the lower composite insulation panel and the upper composite insulation panel, respectively. Furthermore, according to various embodiments, because the first composite insulation panel 110 is closest to the inner surface 11 of the storage tank 1, it can be referred to as the inner composite insulation panel, and because the second composite insulation panel 130 is closest to the outer surface of the insulation system 100, it can be referred to as the outer composite insulation panel. Alternatively, according to various embodiments, because the first composite insulation panel 110 is composed of multiple layers, it can be referred to as a multi-layer composite insulation panel, and because the second composite insulation panel 130 is disposed on the upper layer of the first composite insulation panel 110 and the connecting composite insulation panel 120, it can be referred to as the upper composite insulation panel.

[0069] The first composite insulation panel 110 may include multiple insulation layers 112 and 116, multiple retaining layers 113, 115 and 117, and multiple protective layers 111, 114 and 118. The connecting composite insulation panel 120 may include an insulation layer 122, multiple retaining layers 121 and 123, and a protective layer 124. The second composite insulation panel 130 may include an insulation layer 132, a retaining layer 133, and multiple protective layers 131 and 134.

[0070] In this specification, terms such as "first" and "second" are used to refer to the insulation layer, retaining layer, and protective layer included in each of the first composite insulation panel 110, the connecting composite insulation panel 120, and the second composite insulation panel 130, in order to distinguish these insulation layers, retaining layers, and protective layers from one another. However, apart from some differences in size and / or location, the insulation layers, retaining layers, and protective layers can be understood to have substantially the same construction and perform the same function and role.

[0071] Reference Figure 3 The first composite insulation board 110 may include a first insulation layer 112 and a second insulation layer 116. The first composite insulation board 110 may include a first retaining layer 113, a second retaining layer 115 and a third retaining layer 117. The first composite insulation board 110 may include a first protective layer 111 (lower protective layer), a second protective layer 114 and a third protective layer 118.

[0072] The first composite insulation board 110 may have a shape in which the first protective layer 111, the first insulation layer 112, the first retaining layer 113, the second protective layer 114, the second retaining layer 115, the second insulation layer 116, the third retaining layer 117 and the third protective layer 118 are laminated in sequence.

[0073] The plurality of insulation layers 112 and 116 of the first composite insulation panel 110 can perform the function of providing insulation performance for the first composite insulation panel 110.

[0074] The first insulation layer 112 may include a first insulation material I1 and a second insulation material I2. The first insulation material I1 and the second insulation material I2 may be formed of different materials. The first insulation material I1 may be formed of a material with superior structural strength compared to the second insulation material I2, and the second insulation material I2 may be formed of a material with superior insulation performance compared to the first insulation material I1.

[0075] Since the first insulation layer 112 is formed by a combination of the first insulation material I1 and the second insulation material I2, the insulation performance of the first insulation layer 112 can be improved. Therefore, the thickness of the first composite insulation board 110 can be reduced by making the thickness of the first insulation layer 112 thinner.

[0076] The first insulation material I1 can be formed of a material with superior tensile strength compared to the second insulation material I2. The second insulation material I2 can be made of a material with lower thermal conductivity than the first insulation material I1. For example, the first insulation material I1 can be formed of reinforced polyurethane foam (RPUF), and the second insulation material I2 can be formed of a vacuum insulation panel (VIP). However, the materials of the first insulation material I1 and the second insulation material I2 are merely examples and are not limited thereto.

[0077] According to various embodiments, the first insulation material I1 may be formed of polyurethane foam (PUF), phenolic foam, lightweight concrete or plywood, and the second insulation material I2 may be formed of aerogel, glass microspheres, melamine foam, polystyrene foam or polyethylene foam.

[0078] The first insulation material I1 can be bonded to the second insulation material I2. For example, the first insulation layer 112 can be provided in the form of the first insulation material I1 and the second insulation material I2 bonded together to form an integral structure.

[0079] The first thermal insulation material I1 may have multiple openings, into which the second thermal insulation material I2 may be accommodated or inserted and joined. For example, the first thermal insulation material I1 may have four rectangular openings symmetrically formed with respect to the center of the first thermal insulation material I1, and the second thermal insulation material I2 may be joined by being inserted into the openings of the first thermal insulation material I1. The second thermal insulation material I2 may be formed in a shape corresponding to the openings of the first thermal insulation material I1.

[0080] The first insulation layer 112 can be formed in a rectangular shape. Meanwhile, Figure 3 The shape of the first insulation layer 112 shown is exemplary, and the size, shape, and bonding structure of the first insulation material I1 and the second insulation material I2 are not limited to the forms shown.

[0081] Apart from its size, the second insulation layer 116 may have a substantially the same construction as the first insulation layer 112 and may perform the same function.

[0082] For example, like the first insulation layer 112, the second insulation layer 116 may include a first insulation material I1 and a second insulation material I2, and the first insulation material I1 and the second insulation material I2 of the second insulation layer 116 may be the same as the first insulation material I1 and the second insulation material I2 of the first insulation layer 112.

[0083] The second insulation layer 116 can be smaller than the first insulation layer 112 and is disposed on the central portion of the first insulation layer 112. For example, the vertical area of ​​the second insulation layer 116 can be smaller than the vertical area of ​​the first insulation layer 112. The second insulation layer 116 can be formed into a rectangular shape smaller than the rectangular shape of the first insulation layer 112. The vertical area of ​​the second insulation layer 116 can be smaller than the vertical area of ​​the first insulation layer 112, but the second insulation layer 116 and the first insulation layer 112 can have the same height. However, the second insulation layer 116 and the first insulation layer 112 can also have different heights.

[0084] The second insulation layer 116 and the first insulation layer 112 can be laminated so that their central axes coincide. That is, the first insulation layer 112 and the second insulation layer 116 can be aligned so that their respective centers are on the same axis. For example, when the first composite insulation panel 110 is viewed from above the third protective layer 118, the second insulation layer 116 is located at the center of the first insulation layer 112.

[0085] The plurality of retaining layers 113, 115, and 117 of the first composite insulation panel 110 can perform the function of protecting the plurality of insulation layers 112 and 116. For example, the plurality of retaining layers 113, 115, and 117 can protect the plurality of insulation layers 112 and 116 (especially the second insulation material I2 of the insulation layer) from external impacts. In addition, at least some of the plurality of retaining layers 113, 115, and 117 can be used as layers for mounting other processing equipment (e.g., hole processing). For example, insertion holes or protective layers can be installed in the plurality of retaining layers 113, 115, and 117.

[0086] The first retaining layer 113 may be disposed on the upper part of the first insulation layer 112. The first retaining layer 113 may cover the upper surface of the first insulation layer 112. For example, the first retaining layer 113 may have the same area as the upper surface of the first insulation layer 112. The thickness of the first retaining layer 113 may be formed to be thinner than the thickness of the first insulation layer 112.

[0087] The second retaining layer 115 may be disposed on the lower part of the second insulation layer 116, and the third retaining layer 117 may be disposed on the upper part of the second insulation layer 116. The second retaining layer 115 may cover the lower surface of the second insulation layer 116, and the third retaining layer 117 may cover the upper surface of the second insulation layer 116. For example, the second retaining layer 115 and the third retaining layer 117 may have the same area as the upper and lower surfaces of the second insulation layer 116. The thickness of the second retaining layer 115 and the third retaining layer 117 may be formed to be thinner than the thickness of the second insulation layer 116.

[0088] At least a portion of the first retaining layer 113, the second retaining layer 115, and the third retaining layer 117 may be formed of the same material as the first insulation material I1 (e.g., RPUF). However, the materials of the first retaining layer 113, the second retaining layer 115, and the third retaining layer 117 may not be the same as the material of the first insulation material I1, and are not particularly limited thereto. Furthermore, the first retaining layer 113, the second retaining layer 115, and the third retaining layer 117 may be formed of the same material or different materials.

[0089] At least a portion of the first retaining layer 113, the second retaining layer 115, and the third retaining layer 117 may be formed of a material having superior structural strength compared to the second insulation material I2. For example, retaining layers 113, 115, and 117 may be formed of a material capable of providing stable structural strength for the first composite insulation panel 110.

[0090] The first protective layer 111 may be disposed on the lower part of the first insulation layer 112. For example, the first protective layer 111 may be a layer protecting the lower part of the first insulation layer 112. An adhesive structure 190 may be disposed on the lower part of the first composite insulation board 110, and the first protective layer 111 may be bonded to the adhesive structure 190. For example, the first protective layer 111 may have high rigidity to ensure adhesion to the adhesive structure 190. The first protective layer 111 may have the same area as the lower surface of the first insulation layer 112.

[0091] The second protective layer 114 may be disposed between the first retaining layer 113 and the second retaining layer 115. The second protective layer 114 may be a layer for protecting (e.g., together with the first retaining layer 113) the upper part of the first insulation layer 112, protecting (e.g., together with the second retaining layer 115) the lower part of the second insulation layer 116, and easily disposing the second retaining layer 115 on the upper part of the first retaining layer 113. The second protective layer 114 may have the same area as the upper surface of the first insulation layer 112.

[0092] However, the second protective layer 114 is not a necessary component, and according to various embodiments, the second protective layer 114 can be omitted when the first insulation layer 112 and the second insulation layer 116 are adequately protected by the first retaining layer 113 and the second retaining layer. When the second protective layer 114 is omitted, the second retaining layer 115 can be bonded to the first retaining layer 113.

[0093] The third protective layer 118 may be disposed on the upper part of the third retaining layer 117. The third protective layer 118 protects (e.g., together with the third retaining layer 117) the upper part of the second insulation layer 116, and, although in Figure 3 The third protective layer 118 is not shown, but may be a layer for mounting joint structures (e.g., anchor strips) if necessary. The third protective layer 118 may have the same area as the upper surface of the second insulation layer 116.

[0094] However, the third protective layer 118 is not a necessary component, and according to various embodiments, the third protective layer 118 can be omitted when the protection of the second insulation layer 116 by the third retaining layer 117 is sufficient and when the anchor strip is not required. For example, when the anchor strip is not required on the first composite insulation panel 110, the second barrier 140 is formed of a composite material, and the second barrier 140 is not joined by welding, as will be referred to below. Figure 7 and Figure 8 Detailed description.

[0095] The first composite insulation board 110 includes a first part 110a and a second part 110b. The first part 110a has a laminated structure of a first protective layer 111, a first insulation layer 112, a first retaining layer 113, and a second protective layer 114. The second part 110b has a laminated structure of a second retaining layer 115, a second insulation layer 116, a third retaining layer 117, and a third protective layer 118. The second part 110b can be provided integrated with the first part 110a by being bonded to the center of the first part 110a. For example, the second retaining layer 115 of the second part 110b can be bonded to the second protective layer 114 of the first part 110a.

[0096] The second portion 110b is formed such that the area of ​​its upper and lower surfaces is smaller than the area of ​​the upper and lower surfaces of the first portion 110a, and can be bonded to the center of the upper surface of the first portion 110a. Therefore, when a plurality of first composite insulation panels 110 are arranged in a row, a raised and recessed pattern can be formed through one or more spaces between adjacent second portions 110b. The connecting composite insulation panel 120, which will be described below, can be disposed in one or more spaces between adjacent second portions 110b.

[0097] Reference Figure 4 The composite insulation board 120 may include a third insulation layer 122, a fourth retaining layer 121, a fifth retaining layer 123, and a fourth protective layer 124.

[0098] The composite insulation panel 120 may have a shape in which the fourth retaining layer 121, the third insulation layer 122, the fifth retaining layer 123 and the fourth protective layer 124 are laminated in sequence.

[0099] The insulation layer 122, retaining layers 121 and 123, and protective layer 124 disposed in the connecting composite insulation panel 120 can be applied in the same manner as described above. Figure 3 The description of the insulation layers 112 and 116, the retaining layers 113, 115 and 117, and the protective layers 111, 114 and 118 of the first composite insulation panel 110 is omitted below due to its redundancy.

[0100] When multiple first composite insulation panels 110 are provided, connecting composite insulation panels 120 can be provided between the second insulation layers 116 of adjacent first composite insulation panels 110 to connect adjacent second insulation layers 116. For example, connecting composite insulation panels 120 can be provided between the second portions 110b of adjacent first composite insulation panels 110 to connect adjacent first composite insulation panels 110.

[0101] The connecting composite insulation panel 120 can be disposed between the second portions 110b of adjacent first composite insulation panels 110 and attached to the first portion 110a of adjacent first composite insulation panels 110.

[0102] The connecting composite insulation panel 120 may have substantially the same size and structure as the second part 110b of the first composite insulation panel 110 (in which a second retaining layer 115, a second insulation layer 116, a third retaining layer 117 and a third protective layer 118 are laminated).

[0103] For example, the fourth retaining layer 121, the third insulation layer 122, the fifth retaining layer 123 and the fourth protective layer 124 connecting the composite insulation panel 120 can each be understood to have substantially the same size, area, material or shape as the second retaining layer 115, the second insulation layer 116, the third retaining layer 117 and the third protective layer 118 of the first composite insulation panel 110.

[0104] Anchor strips C1 may be disposed in the fourth protective layer 124 connecting the composite insulation panel 120. Anchor strips C1 are components used for welding the second barrier 140, and when the second barrier 140 is formed of a metallic material, anchor strips C1 may be disposed in the fourth protective layer 124 for welding the second barrier 140. The number and / or position of anchor strips C1 disposed in the fourth protective layer 124 may vary in various ways to correspond to the positions required for welding the second barrier 140. In various embodiments, when the second barrier 140 is formed of a composite material, anchor strips C1 may be omitted because welding of the second barrier 140 is not required.

[0105] Similar to the third protective layer 118 of the first composite insulation panel 110, the fourth protective layer 124 connecting the composite insulation panel 120 is not a necessary component. In various embodiments, the fourth protective layer 124 may be omitted when the third insulation layer 122 is adequately protected by the fifth retaining layer 123 and when the anchoring strip C1 is not required (e.g., when the second barrier 140 is formed of a composite material).

[0106] Reference Figure 5 The second composite insulation board 130 may include a fourth insulation layer 132, a sixth retaining layer 133, a fifth protective layer 131 (intermediate protective layer) and a sixth protective layer 134 (upper protective layer).

[0107] The second composite insulation board 130 may have a shape in which the fifth protective layer 131, the fourth insulation layer 132, the sixth retaining layer 133 and the sixth protective layer 134 are laminated in sequence.

[0108] The insulation layer 132, retaining layer 133, and protective layers 131 and 134 disposed in the second composite insulation panel 130 can be applied in the same manner as described above. Figure 3 The description of the insulation layers 112 and 116, the retaining layers 113, 115 and 117, and the protective layers 111, 114 and 118 of the first composite insulation panel 110 is omitted below due to redundant description.

[0109] When multiple first composite insulation panels 110 are provided and multiple connecting composite insulation panels 120 are provided between adjacent second portions 110b of the first composite insulation panels 110, the second composite insulation panel 130 can be provided on the second portion 110b of the first composite insulation panel 110 and the upper part of the connecting composite insulation panel 120.

[0110] The second composite insulation panel 130 can be laminated on the upper part of the second barrier 140, which is disposed on the second part 110b of the first composite insulation panel 110 and the upper part of the connecting composite insulation panel 120.

[0111] The second composite insulation panel 130 may have substantially the same area and structure as the first portion 110a of the first composite insulation panel 110 (wherein a first protective layer 111, a first insulation layer 112, a first retaining layer 113, and a second protective layer 114 are laminated). The height of the second composite insulation panel 130 may be the same as or different from the height of the first portion 110a of the first composite insulation panel 110.

[0112] For example, the fifth protective layer 131, the fourth insulation layer 132, the sixth retaining layer 133, and the sixth protective layer 134 of the second composite insulation panel 130 can each be understood to have substantially the same area, material, or shape as the first protective layer 111, the first insulation layer 112, the first retaining layer 113, and the second protective layer 114 of the first composite insulation panel 110.

[0113] One or more anchoring strips C1 may be disposed in the sixth protective layer 134 of the second composite insulation panel 130. The anchoring strips C1 are components used for welding the first barrier 150 and may be disposed in the fourth protective layer 124 to weld and secure the first barrier 150 to the upper part of the second composite insulation panel 130. The number and / or position of the anchoring strips C1 disposed in the fourth protective layer 124 may vary in various ways to correspond to the positions required for welding the first barrier 150.

[0114] When the second barrier 140 is formed of a metallic material and is connected to the first composite insulation panel 110 using a fastening member C2 disposed in the first composite insulation panel 110, the fifth protective layer 131 can be penetrated by the fastening member C2.

[0115] Meanwhile, when the second barrier 140 is formed of composite material, the second barrier 140 is bonded to the upper part of the first composite insulation board 110 and the connecting composite insulation board 120, and the second composite insulation board 130 is bonded to the upper part of the second barrier 140. The fifth protective layer 131 can be formed of the same material as the retaining layer.

[0116] Reference Figure 2 and Figure 6 The second barrier 140 is disposed between the first composite insulation board 110 and the upper surface of the connecting composite insulation board 120 and the lower surface of the second composite insulation board 130, and the first barrier 150 may be disposed on the upper surface of the second composite insulation board 130.

[0117] The second barrier 140 and the first barrier 150 are primarily used for storing goods (ensuring airtightness). The second barrier 140 and the first barrier 150 can also serve as protective layers for composite insulation panels 110, 120, and 130. The second barrier 140 and the first barrier 150 can also serve as protective layers to protect insulation layers 112, 116, 122, and 132 (e.g., the first insulation material I1 and the second insulation material I2 of the insulation layers) from external impacts.

[0118] The first barrier 150 may be formed of a metallic material and may be corrugated. The corrugated shape of the first barrier 150 may be flattened by the pressure of another layer of the composite insulation panels 110, 120, and 130 when they are laminated. The first barrier 150 may be formed of stainless steel, but is not limited to this.

[0119] The first barrier 150 can be welded and joined to the anchoring strip C1 disposed on the upper surface of the second composite insulation panel 130 (specifically, the sixth protective layer 134).

[0120] according to Figure 2 and Figure 6 The second barrier 140 of the insulation system 100 in the embodiment can be formed of a metallic or composite material and can be formed in a flat shape. The laminated structure (connection structure) of the insulation system 100 according to the material of the second barrier 140 will be referred to below. Figure 7 and Figure 8 Provide a detailed description.

[0121] In the following text, reference will be made to Figures 2 to 6The lamination configuration of the first composite insulation panel 110, the connecting composite insulation panel 120, and the second composite insulation panel 130 is described.

[0122] The insulation system 100 may have the following shape: a second composite insulation board 130 is laminated on the upper part of a first composite insulation board 110, such that the lower corner P of the second composite insulation board 130 is located at the center of the second part 110b of the first composite insulation board 110, and the second composite insulation board 130 and the first part 110a of the first composite insulation board 110 are laminated in an alternating manner, and a connecting composite insulation board 120 is laminated on the upper part of the first part 110a of the first composite insulation board 110, while filling the empty space between the first part 110a of the first composite insulation board 110 and the second composite insulation board 130.

[0123] Here, the empty space between the first portion 110a of the first composite insulation panel 110 and the second composite insulation panel 130 can be filled by five connected composite insulation panels 120, as the space S formed between the four second portions 110b based on the four adjacent first composite insulation panels 110.

[0124] like Figure 2 As shown, when any four of the first composite insulation panels 110 are used as examples, insulation panel 1-2 110-2 can be positioned to the right of insulation panel 1-1 110-1 relative to insulation panel 1-1, insulation panel 1-3 110-3 can be positioned above insulation panel 1-1 110-1, and insulation panel 1-4 110-4 can be positioned to the right of insulation panel 1-3 110-3.

[0125] When arranged in this manner, the five connecting composite insulation panels 120 are respectively located between the second part 110b of insulation panel 1-1 110-1 and the second part 110b of insulation panel 1-2 110-2 (e.g., left and right), between the second part 110b of insulation panel 1-1 110-1 and the second part 110b of insulation panel 1-3 110-3 (e.g., top and bottom), between the second part 110b of insulation panel 1-2 110-2 and the second part 110b of insulation panel 1-4 110-4 (e.g., top and bottom), between the second part 110b of insulation panel 1-3 110-3 and the second part 110b of insulation panel 1-4 110-4 (e.g., left and right), and between the second part 110b of insulation panel 1-1 110-1 and the second part 110b of insulation panel 1-4 110-4 (e.g., diagonally).

[0126] As described above, when five connecting composite insulation panels 120 are laminated onto four first composite insulation panels 110, a second composite insulation panel 130 can be disposed on the upper part of the four first composite insulation panels 110 and the five connecting composite insulation panels 120, such that the four lower surface corners are positioned adjacent to the central portion of each of the insulation panels 1-1 to 1-4 110-4.

[0127] When Figure 6 When the insulation system 100 is viewed in cross-section, two first composite insulation panels 110 are arranged side by side to form a space S. In this space S, a connecting composite insulation panel 120 is disposed between the second portions 110b of the two first composite insulation panels 110. A second composite insulation panel 130 is arranged in an alternating manner with the first portion 110a of the first composite insulation panel 110, and therefore the second composite insulation panel 130 can overlap with a portion of the second portion 110b of the first composite insulation panel 110 disposed on the left, the connecting composite insulation panel 120, and a portion of the second portion 110b of the first composite insulation panel 110 disposed on the right.

[0128] When Figure 6 When the insulation system 100 is viewed in cross-section, the first composite insulation panel 110 can be configured such that the first insulation material I1 at the center of the first insulation layer 112 and the first insulation material I1 at the center of the second insulation layer 116 overlap vertically. The first insulation layer 112 and the second insulation layer 116 can have the same first insulation material I1 and second insulation material I2 arranged in the same structure, but the width (or cross-sectional area) of the second insulation material I2 of the second insulation layer 116 can be smaller than the width (or cross-sectional area) of the second insulation material of the first insulation layer 112. Furthermore, the connecting composite insulation panel 120 can be configured such that the first insulation material I1 at the center of the third insulation layer 122 vertically overlaps with the first insulation material I1 at the edge portion of each of the first insulation layers 112 of the two adjacent first composite insulation panels 110.

[0129] At the same time, refer to Figure 2 and Figure 6 When multiple first composite insulation panels 110 are fixed to the inner surface 11 of the storage tank 1 by adhesive structure 160, a predetermined gap can be formed between the first portions 110a of adjacent first composite insulation panels 110. The connecting composite insulation panel 120 can be disposed in the space S between the second portions 110b and overlap with the gap between the first portions 110a, thereby achieving insulation between the space between the first portions 110a and the internal space of the storage tank 1.

[0130] like Figure 6As shown, the first composite insulation panel 110 and the connecting composite insulation panel 120 can constitute the insulation space (IS) region of the insulation system 100, and the second composite insulation panel 130 can constitute the inter-barrier space (IBS) region of the insulation system 100.

[0131] Figure 7 This is a diagram illustrating a case where the first barrier in an insulation system according to an embodiment of the present invention is formed of a composite material and is in the shape of a flat plate. Figure 8 This is a diagram illustrating a case where the first barrier in an insulation system according to an embodiment of the present invention is formed of a metallic material and is in the shape of a flat plate.

[0132] Figure 7 It was shown in Figures 2 to 6 In the case where the second barrier 140 of the insulation system 100 shown is formed of a composite material, and Figure 8 It was shown in Figures 2 to 6 The second barrier 140 in the insulation system 100 shown is formed of a metallic material.

[0133] First, refer to Figure 7 The second barrier 140 is in the shape of a flat plate and can be formed of a composite material. For example, the composite material is a material that readily bonds to the retaining and protective layers at room and low temperatures and is capable of preventing liquid penetration, and may include, but is not limited to, thin metal layers and multiple layers of glass fiber. According to various embodiments, the second barrier 140 can be formed using a variety of materials that allow the second barrier 140 to be bonded to the retaining and protective layers, and particularly prevent delamination between the retaining and protective layers during cooling.

[0134] The planar second barrier 140 formed of composite material can be bonded to composite insulation panels 110, 120 and 130. For example, the lower surface of the second barrier 140 can be bonded to the composite insulation panel 120 and the first composite insulation panel 110 (especially the second part 110b), and the upper surface of the second barrier 140 can be bonded to the second composite insulation panel 130.

[0135] When the second barrier 140 is formed of composite material, no welding or mechanical fastening is required between the second barrier 140 and the composite insulation panels 110, 120 and 130, and no mechanical fastening is required between the first composite insulation panel 110 and the second composite insulation panel 130.

[0136] When the second barrier 140 is formed of composite material, the fastening member C2 for joining the first composite insulation board 110 and the second composite insulation board 130 and the anchoring strip C1 for welding the second barrier 140 and the first composite insulation board 110 are not required. Therefore, the first composite insulation board 110 may not include the third protective layer 118, and the connecting composite insulation board 120 may not include the fourth protective layer 124.

[0137] However, this means that the third protective layer 118 and the fourth protective layer 124 are not necessary, but they are not necessarily excluded. For example, even when the second barrier 140 is formed of a composite material, the third protective layer 118 and the fourth protective layer 124 may be included to protect the insulation layer.

[0138] Furthermore, when the second barrier 140 is formed of a composite material, the fifth protective layer 131 of the second composite insulation panel 130 may be formed of the same material as the retaining layer (e.g., a material such as the first insulation material I1).

[0139] Next, refer to Figure 8 The second barrier 140 can be formed of a metal material into a flat plate shape.

[0140] The second barrier 140, which is a flat plate made of metal material, can be welded to the connecting composite insulation panel 120.

[0141] When the second barrier 140 is formed of a metallic material, the connecting composite insulation panel 120 may be provided with anchoring strips C1 for welding the second barrier 140. For example, the anchoring strips C1 may be provided in the fourth protective layer 124 connecting the composite insulation panels 110, 120, and 130 (e.g., Figure 4 The fourth protective layer 124) is attached to the connecting composite insulation panel 120, and the second barrier 140 can be joined to the anchoring strip C1 by welding at least a portion of the second barrier 140 to the anchoring strip C1.

[0142] When the second barrier 140 is formed of a metallic material, the first composite insulation panel 110 and the second composite insulation panel 130 are mechanically fastened together.

[0143] When the second barrier 140 is formed of a metallic material, the first composite insulation panel 110 may be provided with a fastening member C2 for securing the second composite insulation panel 130. Corresponding to the fastening member C2, the second composite insulation panel 130 may be provided with a fastening hole through which the fastening member C2 passes and is fastened. The fastening hole may be formed by penetrating at least some of the multiple layers vertically at the corner of the second composite insulation panel 130.

[0144] The fastening member C2 can be formed as a stud or a nut, but is not limited to these. For example, the fastening member C2 can be formed as a screw.

[0145] The fastening member C2 can be disposed in the second part 110b of the first composite insulation panel 110. For example, the fastening member C2 can be disposed in the third protective layer 118 of the first composite insulation panel 110 (e.g., Figure 3 In the third protective layer 118). The fastening member C2 can be set at the center of the second part 110b of the first composite insulation board 110.

[0146] Figure 9 This is a diagram illustrating a modified example of an insulation system including a composite insulation panel according to an embodiment of the present invention. Figure 10 It shows the basis Figure 9 A diagram of the second composite insulation panel of the insulation system shown in the modified example. Figure 11 It shows the basis Figure 9 A diagram of the cross-section of the insulation system shown in the modified example.

[0147] Figure 9 It is a three-dimensional view of the insulation system 100' based on the modified example. Figure 10 yes Figure 9 The second composite insulation panel 130' is shown in a perspective view and an exploded perspective view. Figure 11 It is shown schematically. Figure 9 The cross-sectional view of the laminated structure of the insulation system 100' shown.

[0148] Figure 9 An insulation system 100' is shown, which has been modified such that: with Figure 2 Compared to the insulation system 100, the second barrier 140' is deformed into a corrugated shape, and correspondingly, a corrugated receiving portion 135b is formed in the second composite insulation panel 130' to accommodate the corrugated portion of the second barrier 140'.

[0149] Reference Figures 9 to 11 The insulation system 100' according to the modified example may include a first composite insulation panel 110, a connecting composite insulation panel 120, a second composite insulation panel 130', a second barrier 140', and a first barrier 150.

[0150] Figure 9 At least some of the components of the insulation system 100' shown can be connected with Figures 2 to 6 The components of the insulation system 100 shown (e.g., the first composite insulation panel 110, the connecting composite insulation panel 120, the second composite insulation panel 130, the second barrier 140, and the first barrier 150) are substantially the same or similar. Therefore, redundant descriptions will be omitted below, and the description will focus on the modified parts and differences.

[0151] According to the modified example, the second barrier 140' of the insulation system 100' can be formed in a corrugated shape. For example, the second barrier 140' can be formed of the same or similar metallic material as the first barrier 150, and can be formed in a corrugated shape. The corrugated shapes of the second barrier 140' and the first barrier 150 can be the same or different from each other. For example, the spacing between the corrugations of the second barrier 140' and the first barrier 150, the height of the corrugations, and the shape of the corrugations can be the same or different.

[0152] The second barrier 140' can be configured such that the corrugated portion 141 protrudes toward the second composite insulation panel 130'. Therefore, an empty space can be formed between the corrugated portion 141 of the second barrier 140' and the first composite insulation panel 110 or the connecting composite insulation panel 120.

[0153] As described above, since the second barrier 140' is formed of a metallic material, the fastening member C2 can be disposed on the first composite insulation panel 110, and the anchoring strip C1 can be disposed on the connecting composite insulation panel 120. For example, the fastening member C2 can be disposed on the third protective layer of the second portion 110b of the first composite insulation panel 110 (e.g., Figure 3 The third protective layer 118) and the anchoring strip C1 can be set on the fourth protective layer (e.g., the one connecting the composite insulation board 120) Figure 4 In the fourth protective layer 124).

[0154] Reference Figure 10 According to the modified example, the second composite insulation panel 130' of the insulation system 100' may include a fourth insulation layer 132, a sixth retaining layer 133, a seventh retaining layer 135, a fifth protective layer 131, a sixth protective layer 134 and a seventh protective layer 136.

[0155] For example, when used with a second composite insulation panel of the insulation system 100 according to the basic example (e.g., see...) Figure 5 Compared to the second composite insulation panel 130, the second composite insulation panel 130' of the insulation system 100' according to the modified example may also include a seventh retaining layer 135 and a seventh protective layer 136.

[0156] Settings Figure 10 The fourth insulation layer 132, the sixth retaining layer 133, the fifth protective layer 131, and the sixth protective layer 134 in the second composite insulation panel 130' can be referenced above. Figure 5 The second composite insulation panel 130 is applied in the same manner as described above, and therefore these descriptions are replaced by the descriptions above, and additional layers (e.g., the seventh retaining layer 135 and the seventh protective layer 136) are described.

[0157] The seventh retaining layer 135 may be disposed on the lower surface of the fifth protective layer 131. For example, the seventh retaining layer 135 may be attached to the lower surface of the fifth protective layer 131.

[0158] The seventh retaining layer 135 may be a layer in which a corrugated receiving portion 135b is formed, which can partially accommodate the corrugations of the second barrier 140'. For example, as Figure 11 As shown, when the second barrier 140' is welded to the connecting composite insulation board 120 at the upper part of the connecting composite insulation board 110 and the connecting composite insulation board 120, and the second composite insulation board 130' is joined to the first composite insulation board 110 at the upper part of the second barrier 140', the corrugated portion 141 of the second barrier 140' can be accommodated within the corrugated accommodating portion 135b.

[0159] In the seventh retaining layer 135, a plurality of corrugated receiving portions 135b can be formed on the base 135a by recessing or opening at least a portion of the base 135a in correspondence with the corrugations of the second barrier 140'. According to Figure 10 In the embodiment shown, the corrugated receiving portion 135b may be a groove (or recess) in which a portion of the base 135a is recessed, but the corrugated receiving portion 135b may be an opening in which a portion of the base 135a is removed or opened.

[0160] Since the corrugated accommodating portion 135b is formed in the seventh retaining layer 135, the fifth protective layer 131 can be formed to have a certain rigidity in order to maintain the structural stability of the seventh retaining layer 135 and enhance its strength.

[0161] Like the other retaining layers, the seventh retaining layer 135 can be formed of the same material as the first insulating material I1, but is not limited to it.

[0162] A seventh protective layer 136 may be disposed on the lower surface of the seventh retaining layer 135. For example, the seventh protective layer 136 may be attached to the lower surface of the base 135a of the seventh retaining layer 135. The seventh protective layer 136 may have a shape in which the area corresponding to the corrugated receiving portion 135b is opened or cut, such that the corrugated portion 141 of the second barrier 140' can be accommodated in the corrugated receiving portion 135b.

[0163] Since the second barrier 140' is formed of a metallic material, the second composite insulation panel 130' can be provided with fastening holes through which the fastening member C2 can pass and be engaged. The fastening holes can be formed by penetrating at least some of the multiple layers vertically at the corners of the second composite insulation panel 130'.

[0164] Meanwhile, the illustrated embodiment is configured such that the corrugated portion 141 of the second barrier 140' faces the second composite insulation panel 130', but this is exemplary, and the construction of the second barrier 140' is not limited to the form shown.

[0165] According to various embodiments, the second barrier 140' can be configured such that the corrugated portion 141 faces downward (i.e., toward the first composite insulation panel 110 and the connecting composite insulation panel 120), and correspondingly, the corrugated receiving portion 135b can be formed on or by the first composite insulation panel 110 and the connecting composite insulation panel 120. For example, when the corrugated portion 141 of the second barrier 140' faces downward (towards the first composite insulation panel 110 and the connecting composite insulation panel 120), Figure 9 and Figure 10 Conversely, the corrugated receiving portion that can partially accommodate the corrugated portion 141 can be disposed on the positioning surface of the second portion 110b of the first composite insulation board 110 and the second barrier 140' formed by connecting the composite insulation board 120.

[0166] Figure 12 It is shown in accordance with Figure 9 The diagram shows a modified example of an insulation system in which the foam component is disposed in the corrugated portion of the first barrier.

[0167] Figure 12 This diagram illustrates a structure in which, in the modified example insulation system 100', the second barrier 140' has a corrugated shape, and the empty spaces created by the corrugations of the second barrier 140' are filled with foam members 170 and 180. In the following text, reference will be made to... Figures 9 to 11 describe Figure 12 .

[0168] Here, the empty space formed by the corrugations can be the space inside the corrugated portion 141 of the second barrier 140' and the space between the corrugated portion 141 of the second barrier 140' and the corrugated receiving portion 135b of the second composite insulation panel 130'. The space inside the corrugated portion 141 of the second barrier 140' can refer to the space between the corrugated portion 141 and the first composite insulation panel 110 and / or the space between the corrugated portion 141 and the connecting composite insulation panel 120.

For example, the insulation system 100 may include composite insulation panels 110, 120, and 130 comprising shapes 711 and 812.

[0190] The shapes 711, 712, 713, 714, 715, 716, 717, 718, 811, 812, 813 and 814 described above are merely examples, and the shape of the insulation layer 112 is not limited thereto.

[0191] In the following text, reference will be made to Figures 15 to 21 The anti-misalignment structure 2030 is described, which can prevent misalignment when the insulation layer 2010 and the protective layer 2020 are bonded in the composite insulation board 2001.

[0192] Composite insulation panel 2001 can refer to a composite insulation panel configured such that protective layer 2020 is bonded to the upper or lower portion of insulation layer 2010. For example, the first composite insulation panel 110 described above is a composite insulation panel in which first protective layer 111 is disposed on the lower portion of first insulation layer 112, and anti-misalignment structure 2030 can be applied in the same manner. Alternatively, the second composite insulation panel 130' described above is a composite insulation panel in which fifth protective layer 131 is disposed on the lower portion of fourth insulation layer 132, and anti-misalignment structure 2030 can be applied in the same manner.

[0193] Figure 15 This diagram illustrates the process of laminating a protective layer onto the insulation layer during the manufacturing of the insulation panel.

[0194] Figure 16 This is a diagram showing the appearance of a protective layer bonded to the insulation layer in a conventional manner in a composite insulation panel.

[0195] In the conventional manufacturing process of insulation panels comprising a single type of insulation material, there is a step of applying an adhesive to an insulation layer including the insulation material and laminating a protective layer (e.g., plywood) onto the insulation layer. In this case, misalignment can occur between the insulation layer and the protective layer due to manufacturing tolerances or slippage during the pressing process. Previously, misalignment was eliminated by cutting, and insulation materials formed of polyurethane foam did not suffer performance loss even after cutting. However, in the case of composite insulation panels incorporating vacuum insulation material, cutting can damage the outer sheath of the vacuum insulation material, and since the vacuum insulation material is a product that maintains a vacuum through its outer sheath, there is a problem of functional loss. The conventional method for manufacturing insulation panels and the problems that arise when this method is applied to composite insulation panels are described below.

[0196] Reference Figure 15, First, an adhesive 2130 (e.g., glue) is applied to the upper part of the heat insulation layer 2110. Subsequently, the protective layer 2120 is stacked on top of the heat insulation layer 2110 to overlap with the upper part of the heat insulation layer 2110. During this process, misalignment occurs between the heat insulation layer 2110 and the protective layer 2120.

[0197] Specifically, one end of the lower part of the protective layer 2120 may protrude more than the corresponding end of the heat insulation layer 2110, or one end of the lower part of the protective layer 2120 may not reach the corresponding end of the heat insulation layer 2110.

[0198] This phenomenon may occur due to two reasons. First, although the protective layer 2120 is manufactured to fit the shape and size of the heat insulation layer 2110, manufacturing tolerances may occur during this process. Second, a pressing process may be performed to bond the protective layer 2120 to the heat insulation layer 2110, and during this process, sliding may occur due to the adhesive 2130.

[0199] Traditionally, rather than preventing the misalignment between the heat insulation layer 2110 and the protective layer 2120 itself, after the misalignment occurs, the misaligned part is removed through post-processing (e.g., cutting). In the case of a conventional heat insulation material formed only of polyurethane foam, this manufacturing method has no problem because even if it is cut, the performance of the heat insulation material will not deteriorate.

[0200] However, the composite heat insulation panel 2001 includes a second heat insulation material I2 formed of a vacuum heat insulation material, and the outer sheath of the vacuum heat insulation material may be damaged during the cutting process, resulting in the loss of the function of the vacuum heat insulation material.

[0201] Refer to Figure 16 , the composite heat insulation panel 2001 may be composed of a protective layer 2020 and a heat insulation layer 2010 including a first heat insulation material I1 and a second heat insulation material I2.

[0202] The heat insulation layer 2010 is formed such that the first heat insulation material I1 is formed in an I shape and the second heat insulation material I2 fills the empty space, but the structure of the heat insulation layer 2010 is not limited to this. For example, the first heat insulation material I1 may have various shapes, such as shapes like mouth, king, sun, and field in addition to the I shape.

[0203] In this configuration, the first insulation material I1 not only functions as an insulation material but also possesses relatively high structural strength, allowing it to surround and protect the second insulation material I2. The second insulation material I2 exhibits relatively low thermal conductivity, thus providing superior insulation performance compared to using only the first insulation material I1. However, the second insulation material I2 is a product that maintains a vacuum through an outer sheath material, and when the outer sheath is damaged, the internal vacuum may not be maintained, leading to a reduction in insulation performance.

[0204] However, as mentioned above, during the cutting process according to conventional methods, the outer sheath of the second insulation material I2 is damaged, resulting in the loss of its function as a vacuum insulation material. Therefore, to solve this problem, the present invention can form an anti-misalignment structure 2030 between the insulation layer 2010 and the protective layer 2020, so that misalignment does not occur during the bonding process of the insulation layer 2010 and the protective layer 2020, and no cutting process is required. The anti-misalignment structure 2030 will be described in detail through various embodiments.

[0205] <Anti-misalignment structure of the first embodiment>

[0206] Figure 17 This is a diagram illustrating the anti-misalignment structure according to a first embodiment of the present invention.

[0207] The anti-misalignment structure 2030 can be composed of a protrusion 2031 and a groove 2032. The protrusion 2031 is formed in the first thermal insulation material I1, and the groove 2032 has a shape corresponding to the protrusion.

[0208] The protrusion 2031 may not be formed by joining it to a separate structure, but may be created by partially deforming the shape of the first insulating material I1 itself. The groove 2032 may have a shape corresponding to the protrusion 2031. That is, the groove 2032 may have a shape that is fixed in place by joining it to the protrusion 2031.

[0209] When the protective layer 2020 is bonded to the insulation layer 2010, the protrusion 2031 is engaged with the groove 2032 and fixed so that it does not slip during the bonding process, thereby preventing misalignment between the insulation layer 2010 and the protective layer 2020.

[0210] Reference Figure 17 The protrusion 2031 of the first thermal insulation material I1 can be formed as a part of the first thermal insulation material I1 extending vertically in the height direction of the thermal insulation layer 2010.

[0211] The groove 2032 can be formed in the protective layer 2020 to match the shape of the protrusion 2031. Figure 17The protrusion 2031 formed in the middle part of the I-shape is shown, but this is merely an example and is not limited thereto.

[0212] For example, protrusions 2031 can be formed on the edge portion of the I-shape, other parts of the region, or the entire region. The fact that the first insulating material I1 within the insulating layer 2010 is I-shaped is merely an example and is not limited thereto.

[0213] The first insulating material I1 and the second insulating material I2 can be joined in different ways, and therefore, the protrusion 2031 can also be formed in various positions and in various shapes. Furthermore, the protrusion 2031 can all extend at the same height in the height direction, but this is not a limitation as long as misalignment can be prevented, and the protrusion 2031 can be formed in other forms with uneven heights. The depth of the groove 2032 can be formed within 2 mm, but this figure is merely an example and not a limitation.

[0214] <Anti-misalignment structure of the second embodiment>

[0215] Figure 18 This is a diagram illustrating the anti-misalignment structure according to a second embodiment of the present invention.

[0216] Figure 19 This is a diagram illustrating an anti-misalignment structure with improved manufacturability in a second embodiment of the present invention.

[0217] The anti-misalignment structure 2030 may include keyholes 2033 formed in the first thermal insulation material I1 and the protective layer 2020, respectively, and keys 2034 corresponding to the keyholes 2033.

[0218] Keyholes 2033 and keys 2034 fit together perfectly, so that each component with a keyhole 2033 is secured by a key 2034. Keyholes 2033 are formed in the first insulation material I1 and the protective layer 2020 respectively, and each keyhole 2033 corresponds to the others; that is, each keyhole 2033 is interconnected to form a single empty space. Because the keys 2034, perfectly fitted into the empty spaces, are installed and secured, slippage does not occur during bonding, thereby preventing misalignment between the insulation layer 2010 and the protective layer 2020.

[0219] Reference Figure 18 A cylindrical key 2034 can be inserted into a keyhole 2033 formed in the first insulating material I1 and the protective layer 2020 to secure each component. The diameter of the key 2034 can be formed to be 10 to 20 mm, and the height can be formed to be 10 mm, and the depth of the keyhole 2033 can be formed to be 5 mm. However, these figures are merely examples and are not limited thereto. The shape of the key 2034 is also not limited to cylindrical.

[0220] like Figure 19 As shown, keyhole 2033 and key 2034 can be made into shapes that improve manufacturability. This truncated conical or truncated square shape can facilitate installation when the key is inserted into the keyhole. Furthermore, Figure 18 The locations where keyhole 2033 and key 2034 are installed as four parts of an 'I'-shaped edge are shown, but the locations and number are not limited thereto.

[0221] The anti-misalignment structure according to the second embodiment is simple to manufacture because it only requires machining the keyhole 2033.

[0222] <Anti-misalignment structure of the third embodiment>

[0223] Figure 20 This is a diagram illustrating the anti-misalignment structure according to a third embodiment of the present invention.

[0224] The anti-misalignment structure 2030 may include a through hole 2036 formed in the protective layer 2020, a hole 2037 formed in the first thermal insulation material I1, and a fixing member 2038.

[0225] Reference Figure 20 Hole 2037 is formed in the first insulation material I1, and through hole 2036 connected to hole 2037 and extending to the outside can be formed in protective layer 2020. Fixing member 2038 enters from the outside of protective layer 2020, passes through through hole 2036 and is inserted into hole 2037 to be fixed.

[0226] Figure 20 The wedge-shaped fixing member 2038 and corresponding through holes 2036 and 2037 are shown, but the shape of the fixing member 2038 is not limited thereto. Furthermore, Figure 20 The external insertion positions of the four parts that form the edge of the 'I' shape are shown, but their positions and number are not limited to this.

[0227] The anti-misalignment structure according to the third embodiment is easy to operate because the through hole 2036 and hole 2037 can be machined at the same time as the first insulation material I1 and the protective layer 2020 are attached.

[0228] The method for manufacturing a composite insulation panel 2001 for preventing misalignment between the protective layer 2020 and the insulation layer 2010 is as follows.

[0229] First, an insulation layer 2010 is prepared, comprising a first insulation material I1 and a second insulation material I2 formed of a material different from that of the first insulation material I1. In this case, the first insulation material I1 can have superior structural strength compared to the second insulation material I2, and the second insulation material I2 can have superior insulation performance compared to the first insulation material I1.

[0230] Next, a protective layer 2020 is prepared, which is disposed on the upper or lower part of the insulation layer 2010 and serves to protect the insulation layer 2010. In this case, the protective layer 2020 can be formed of plywood.

[0231] Next, an anti-misalignment structure is formed on the insulation layer 2010 and the protective layer 2020. In this case, the anti-misalignment structure can be an anti-misalignment structure according to the first to third embodiments of the present invention.

[0232] Next, adhesive 2040 is applied to the areas where the insulation layer 2010 and the protective layer 2020 are to be joined.

[0233] Finally, the insulation layer 2010 and the protective layer 2020 are joined together by an anti-misalignment structure formed on the insulation layer 2010 and the protective layer 2020.

[0234] Through the above process, the protective layer 2010 and the insulation layer 2020 can be joined without misalignment, and therefore, there is no need to cut and remove the misaligned parts.

[0235] Meanwhile, during the bonding process of the protective layer 2010 and the insulation layer 2020, adhesive 2040 may leak out, and it may be necessary to remove the leaked adhesive 2040. (Refer to...) Figure 15 In conventional methods for manufacturing insulation board 2100, adhesive 2130 leaking from the upper or lower surface of insulation layer 2110 is removed by cutting. However, since the method for manufacturing composite insulation board of the present invention does not have a cutting step, adhesive 2040 should be removed by another method.

[0236] Reference Figure 21 Before bonding the protective layer 2020 to the insulation layer 2010, masking tape 2041 is applied to the side surfaces (excluding the top and bottom surfaces) of the insulation layer 2010. After the bonding process, when the masking tape 2041 is removed, any leaked adhesive 2040 adheres to the masking tape 2041 and is removed together. In this way, only the adhesive 2040 can be removed without damaging the insulation layer 2010 and the protective layer 2020.

[0237] In the foregoing, although the invention has been described with reference to exemplary embodiments thereof, those skilled in the art will understand that various modifications and changes may be made without departing from the scope and spirit of the invention as disclosed in the appended claims.
