[0033] A second aspect of this disclosure provides a mobile cold storage unit using corrugated panels, comprising:

[0034] Library body; and

[0035] A corrugated board assembly is connected to the outside of the warehouse body. The corrugated board assembly includes a plurality of corrugated boards provided in the first aspect of this disclosure, the plurality of corrugated boards being configured to be sequentially inserted along the width direction of the corrugated boards.

[0036] In some embodiments of the mobile cold storage, a fixing device is also included, which is configured to fix the first plug-in portion and / or the second plug-in portion to the storage body.

[0037] In some embodiments of mobile cold storage,

[0038] The first insertion part includes a first insertion groove, which includes a first bottom wall connected to a first end of the main body along the width direction of the corrugated plate, a first side wall of the first insertion groove and a second side wall of the first insertion groove connected to the first bottom wall along the thickness direction of the corrugated plate, and a first slot formed on the side of the first insertion groove away from the main body.

[0061] In the following description, the term "first end along the width direction of corrugated plate 1" corresponds to Figure 1 , Figure 5 and Figure 6 The right end; the so-called "second end along the width direction of corrugated plate 1" corresponds to Figure 1 , Figure 5 and Figure 6 The left end; the so-called "first end along the thickness direction of corrugated plate 1" corresponds to Figure 1 , Figure 5 and Figure 6 The upper end; the so-called "second end along the thickness direction of corrugated plate 1" corresponds to Figure 1 , Figure 5 and Figure 6 The lower end.

[0062] like Figure 1 , Figure 5and Figure 6 As shown, this embodiment of the present disclosure provides a corrugated sheet 1. The corrugated sheet 1 includes a main body portion 13, a first insertion portion 11, and a second insertion portion 12. The first insertion portion 11 is located at a first end of the main body portion 13 along the width direction of the corrugated sheet 1. The second insertion portion 12 is located at a second end of the main body portion 13 along the width direction. The first insertion portion 11 of the corrugated sheet 1 is configured to be able to be inserted into the second insertion portion 12 of another corrugated sheet 1 along the width direction, and the inserted first insertion portion 11 and the second insertion portion 12 are configured to form a support cavity 1A surrounded by sidewalls whose extending direction is consistent with the extending direction of the corrugated sheet 1.

[0063] Based on the corrugated sheet 1 provided in this disclosure, a first insertion part 11 and a second insertion part 12 are inserted along the width direction of the corrugated sheet 1, and the inserted first insertion part 11 and the second insertion part 12 form a support cavity 1A surrounded by sidewalls whose extension direction is consistent with the extension direction of the corrugated sheet 1. The support cavity 1A formed between the two inserted corrugated sheets 1 is beneficial in two ways: firstly, it strengthens the connection strength and structural strength between the two corrugated sheets 1, thereby improving the reliability of the connection between two adjacent corrugated sheets 1; secondly, it helps to prevent external pollutants (such as rainwater, dust, etc.) from eroding the connection position of the corrugated sheets 1, which helps to maintain the connection reliability and thus helps to extend the service life of the corrugated sheet 1. In addition, the assembly of each corrugated sheet 1 by insertion helps to reduce the construction difficulty and improve the installation efficiency.

[0064] In some embodiments, the corrugated sheet 1 is made of an alloy material, such as aluminum alloy, magnesium alloy, aluminum-magnesium alloy, titanium alloy, etc. In other embodiments, the corrugated sheet 1 may also be made of, for example, galvanized material.

[0065] In some embodiments, the edges of the corrugated sheet 1 may be sanded to avoid installation problems caused by sharp edges.

[0066] like Figure 1 and Figure 6As shown, in some embodiments, the first insertion portion 11 includes a first insertion groove 11a. The first insertion groove 11a includes a first bottom wall 111 connected to a first end of the main body portion 13 along the width direction of the corrugated sheet 1, a first insertion groove first side wall 112 and a first insertion groove second side wall 113 connected to the first bottom wall 111 along the thickness direction of the corrugated sheet 1, respectively. A first groove is formed on the side of the first insertion groove 11a opposite to the main body portion 13. The second insertion portion 12 includes a second insertion groove 12a. The second insertion groove 12a includes a second bottom wall 121 connected to a second end of the main body portion 13 along the width direction of the corrugated sheet 1, a second insertion groove first side wall 122 and a second insertion groove second side wall 123 connected to the second bottom wall 121 along the thickness direction of the corrugated sheet 1, respectively. A second groove is formed on the side of the second insertion groove 12a opposite to the main body portion 13. The first plug-in portion 11 and the second plug-in portion 12 are configured to support the cavity 1A. Part of the sidewall is formed by at least a portion of the first sidewall 112 of the first plug-in groove overlapping with at least a portion of the first sidewall 122 of the second plug-in groove and / or by at least a portion of the second sidewall 113 of the first plug-in groove overlapping with at least a portion of the second sidewall 123 of the second plug-in groove.

[0067] The first insertion part 11 includes a first insertion groove 11a, and the second insertion part 12 includes a second insertion groove 12a. A portion of the sidewall of the support cavity 1A is formed by overlapping at least a portion of the first sidewall 112 of the first insertion groove 11a with at least a portion of the first sidewall 122 of the second insertion groove and / or by overlapping at least a portion of the second sidewall 113 of the first insertion groove with at least a portion of the second sidewall 123 of the second insertion groove. The overlapping first sidewall 112 of the first insertion groove and the first sidewall 122 of the second insertion groove and / or the first sidewall 113 of the first insertion groove and the second sidewall 123 of the second insertion groove are beneficial to thickening the sidewall of the support cavity 1A, thereby strengthening the structural strength and bending resistance of the insertion position of the two corrugated plates 1, and thus improving the reliability of the connection.

[0068] In some embodiments, at least one of the first sidewall 112 and the second sidewall 113 of the first insertion slot 11a, the end of which is away from the main body 13, is located between the first sidewall 122 and the second sidewall 123 of the second insertion slot 12a that is inserted into the first insertion slot 11a; or at least one of the first sidewall 122 and the second sidewall 123 of the second insertion slot 12a, the end of which is away from the main body 13, is located between the first sidewall 112 and the second sidewall 113 of the first insertion slot 11a that is inserted into the second insertion slot 12a.

[0069] For example, such as Figure 6As shown, the ends of the first sidewall 122 and the second sidewall 123 of the second insertion slot that are away from the main body 13 are located between the first sidewall 112 and the second sidewall 113 of the first insertion slot 11a that is inserted into the second insertion slot 12a.

[0070] For example, in an embodiment not shown, one end of the first sidewall 112 of the first insertion slot that is away from the main body 13 may be located between the first sidewall 122 and the second sidewall 123 of the second insertion slot 12a that is inserted into the first insertion slot 11a, and the second sidewall 123 of the second insertion slot is located between the first sidewall 112 and the second sidewall 113 of the first insertion slot.

[0071] The ends of the first sidewall 112 and the second sidewall 113 of the first insertion groove 11a that are away from the main body 13 are both located between the first sidewall 122 and the second sidewall 123 of the second insertion groove 12a that are inserted into the first insertion groove 11a. Alternatively, the ends of the first sidewall 122 and the second sidewall 123 of the second insertion groove 12a that are away from the main body 13 are both located between the first sidewall 112 and the second sidewall 113 of the first insertion groove 11a that are inserted into the second insertion groove 12a. This arrangement allows the narrower groove in the first and second grooves along the thickness direction of the corrugated plate 1 to be inserted from the wider groove, thereby enabling the sidewall of the first insertion groove 11a or the second insertion groove 12a where the wider groove is located to play a guiding role, which is beneficial for quick and accurate alignment and splicing.

[0072] One end of one of the first sidewall 112 and the second sidewall 113 of the first insertion slot 11a, which is away from the main body 13, is located between the first sidewall 122 and the second sidewall 123 of the second insertion slot 12a, which is inserted into the first insertion slot 11a. Alternatively, one end of one of the first sidewall 122 and the second sidewall 123 of the second insertion slot 12a, which is away from the main body 13, is located between the first sidewall 112 and the second sidewall 113 of the first insertion slot 11a, which is inserted into the second insertion slot 12a. This arrangement facilitates the mutual interlocking of the first slot opening of the first insertion slot 11a and the second slot opening of the second insertion slot 12a, which is inserted into the first insertion slot 11a, thereby achieving mechanical interlocking and improving the shear strength of the connection structure.

[0073] like Figure 1 and Figure 6As shown, in some embodiments, along the width direction of the corrugated plate 1, the size of the first sidewall 112 of the first insertion slot is smaller than the size of the second sidewall 113 of the first insertion slot; and / or along the width direction of the corrugated plate 1, the size of the first sidewall 122 of the second insertion slot is larger than the size of the second sidewall 123 of the second insertion slot.

[0074] This arrangement allows the first insertion slot 11a and / or the second insertion slot 12a to form an asymmetrical shape along the thickness direction of the corrugated plate 1, which facilitates a more intuitive understanding of the structure of the corrugated plate 1. This, in turn, facilitates the rapid installation and positioning of the corrugated plate 1. Furthermore, when the interlocking first insertion slot 11a and the second insertion slot 12a form the sidewalls surrounding the supporting cavity 1A, it provides suitable operating space when the corrugated plate 1 is connected to the protected equipment, such as the body 8 of a mobile cold storage.

[0075] like Figure 1 and Figure 6 As shown, in some embodiments, the first insertion portion 11 includes a rib 114. The rib 114 is located between the first sidewall 112 and the second sidewall 113 of the first insertion slot along the thickness direction of the corrugated plate 1, forming a first gap 11b with the first sidewall 112 and a second gap 11c with the second sidewall 113. The first gap 11b is configured to receive the end of the first sidewall 122 of the second insertion slot 12a that is inserted into the first insertion slot 11a therewith, away from the main body portion 13.

[0076] The first gap 11b formed by the rib 114 and the first sidewall 112 of the first insertion groove facilitates the rapid insertion of the end of the first sidewall 122 of the second insertion groove 12a away from the main body 13 into the first gap 11b. This facilitates the rapid alignment and insertion of the first insertion part 11 and the second insertion part 12, thereby improving the installation efficiency of the corrugated sheet 1. In addition, the rib 114 helps to bear bending stress and shear stress, thereby improving the connection strength at the connection position of the two corrugated sheets 1.

[0077] like Figure 1 and Figure 6 As shown, in some embodiments, the size of the rib 114 is larger than the size of the first sidewall 112 of the first insertion slot along the width direction of the corrugated plate 1; and / or the size of the rib 114 is smaller than the size of the second sidewall 113 of the first insertion slot along the width direction of the corrugated plate 1.

[0078] Along the width direction of the corrugated board 1, the size of the rib 114 is larger than the size of the first side wall 112 of the first insertion slot. This is beneficial because the first side wall 112 of the first insertion slot does not block the first side wall 122 of the second insertion slot that needs to be inserted into the first interval 11b. This facilitates the quick insertion of the two corrugated boards 1 and also helps to prevent the first side wall 122 of the second insertion slot from colliding with the first side wall 112 of the first insertion slot during the insertion process, thus preventing damage to the corrugated board 1.

[0079] Along the width direction of the corrugated plate 1, the size of the rib 114 is smaller than the size of the second side wall 113 of the first insertion slot. This facilitates the observation of whether the first insertion part 11 is intact when assembling adjacent corrugated plates 1 and makes it easier to repair the deformed first insertion part. This ensures a good fit when assembling adjacent corrugated plates 1. In addition, it also helps to provide suitable operating space when connecting the corrugated plate 1 to the protected equipment such as the body 8 of a mobile cold storage through the second side wall 113 of the first insertion slot.

[0080] like Figure 5 and Figure 6 As shown, in some embodiments, along the thickness direction of the corrugated plate 1, the dimension of the end of the first sidewall 122 of the second insertion groove away from the main body 13 is smaller than the dimension of the first interval 11b.

[0081] After the two corrugated boards 1 are inserted together, the first gap 11b can be filled with sealant or other materials for sealing.

[0082] This design helps reduce frictional resistance during the insertion process, thereby improving installation efficiency.

[0083] like Figure 5 and Figure 6 As shown, in some embodiments, the end of the second sidewall 113 of the first insertion slot 11a away from the main body 13 includes a first mating portion 1131. The end of the second sidewall 123 of the second insertion slot 12a away from the main body 13 includes a second mating portion 1231. The second mating portion 1231 is configured to overlap with the first mating portion 1131 of the first insertion slot 11a to which it is inserted. The surface of the overlapping portion 31 formed by the overlap of the first mating portion 11 and the second mating portion 1231, on the side away from the first end in the thickness direction of the corrugated board 1, is flush with the surface of the corresponding side of the portion of the second sidewall 113 of the first insertion slot 113 other than the first mating portion 1131 of the second sidewall 113 and the second sidewall 123 of the second insertion slot 123 other than the second mating portion 1231 of the second sidewall 123.

[0084] The surface of the overlapping portion 31 formed by the overlap of the first mating portion 1131 and the second mating portion 1231, away from the first end in the thickness direction of the corrugated plate 1, is flush with the surface of the portion of the second side wall 113 of the first insertion groove other than the first mating portion 1131 and the corresponding surface of the portion of the second side wall 123 of the second insertion groove other than the second mating portion 1231. This arrangement helps to improve the flatness of the installation surface formed by the corrugated plate 1 after insertion, and helps to make the corrugated plate 1 fit with other equipment for installation, thereby improving the installation stability.

[0085] like Figure 1 , Figure 5 and Figure 6 As shown, in some embodiments, a first L-shaped groove for receiving the second mating part 1231 is formed on one side of the first end of the first mating part 1131 away from the thickness direction of the corrugated plate 1; or a second L-shaped groove for receiving the first mating part 1131 is formed on one side of the second mating part 1231 away from the thickness direction of the corrugated plate 1.

[0086] The first L-shaped groove accommodates the second mating part 1231 or the second L-shaped groove accommodates the first mating part 1131. This facilitates the installation and positioning of the second side wall 113 of the first insertion groove and the second side wall 123 of the second insertion groove along the width and thickness directions of the corrugated plate 1 through the first mating part 1131 and the second mating part 1231. This improves the installation efficiency of the corrugated plate 1 and also enhances the structural stability.

[0087] like Figure 1 , Figures 4 to 6 As shown, in some embodiments, at least a portion of the main body portion 13 is larger in size than the first insertion portion 11 and the second insertion portion 12 along the thickness direction of the corrugated plate 1.

[0088] Having at least a portion of the main body 13 thicker than the first insertion portion 11 and the second insertion portion 12 facilitates the application of external forces along the thickness direction of the corrugated board 1 to the main body 13 first, making the main body 13 the main stress-bearing area, thereby reducing the impact of external forces on the connection position of the corrugated board 1.

[0089] like Figures 1 to 6 As shown, in some embodiments, the main body 13 includes a first outer wall 131 and a second outer wall 132 respectively disposed at a first end and a second end along the thickness direction of the corrugated plate 1. The first outer wall 131 is configured as an arched wall arching toward the side away from the second outer wall 132.

[0090] The first outer wall 131 is configured as an arched wall that arches toward the side away from the second outer wall 132. The mechanical structure formed by the arched wall is conducive to converting external pressure into longitudinal stress distributed along the arched surface, which is beneficial to improving the bending strength and load-bearing capacity of the corrugated plate 1.

[0091] like Figures 2 to 6 As shown, another aspect of this disclosure provides a mobile cold storage unit, which includes a storage body 8 and a corrugated board assembly. The corrugated board assembly is connected to the outside of the storage body 8. The corrugated board assembly includes a plurality of corrugated boards 1 provided in this disclosure embodiment. The plurality of corrugated boards 1 are configured to be sequentially inserted along the width direction of the corrugated boards 1.

[0092] The mobile cold storage unit of this disclosure has the advantages of the corrugated board of this disclosure. Furthermore, the corrugated board assembly formed by the interlocking corrugated boards 1 is connected to the outside of the cold storage unit body 8. The support cavity 1A formed after the two corrugated boards 1 are interlocked facilitates the formation of at least two layers of support structure along the thickness direction of the corrugated board 1 at the connection point, which helps to strengthen the structural strength and load-bearing capacity of the corrugated board assembly, thereby enhancing the protective capability of the corrugated board assembly for the cold storage unit body 8.

[0093] like Figure 3 As shown, in some embodiments, the mobile cold storage also includes a fixing device 6. The fixing device 6 is configured to fix the first insertion portion 11 and / or the second insertion portion 12 to the cold storage body 8.

[0094] The fixing device 6 forms a rigid connection between the corrugated plate assembly and the cold storage body 8, which helps to disperse the dynamic loads (such as vibration and impact) generated during the movement or transportation of the cold storage, strengthens the connection stability of the first insertion part 11 and the second insertion part 12, and helps to prevent the connection position between the two corrugated plates 1 from loosening or deforming due to local stress concentration.

[0095] In other embodiments (not shown), the corrugated board assembly 1 can also be fixedly connected to the outside of the warehouse body 8 by means of adhesive or other methods.

[0096] like Figure 3 As shown, in some embodiments, the second sidewall 113 of the first insertion slot and the second sidewall 123 of the second insertion slot are fitted to the housing body 8. The fixing device 6 is configured to fix the second sidewall 113 of the first insertion slot or the second sidewall 123 of the second insertion slot to the housing body 8.

[0097] This arrangement facilitates a stable connection between the corrugated sheet 1 and the warehouse body 8, reduces the size of the fixing device 6, and thus helps to speed up the installation efficiency of the corrugated sheet assembly.

[0098] like Figure 3 As shown, in some embodiments, the fixing devices 6 may be spaced apart along the extension direction of the corrugated plate 1.

[0099] The following combination Figures 1 to 6 The corrugated board 1 and the mobile cold storage using the corrugated board 1 according to the embodiments of this disclosure will be described in detail.

[0100] like Figure 1 , Figure 5 and Figure 6 As shown, the corrugated sheet 1 includes a main body 13, a first insertion portion 11, and a second insertion portion 12. The dimensions of the corrugated sheet 1 are, for example, a wall thickness of 1.2 mm, a width of 143 mm, a length of 2800 mm, and a maximum dimension along the thickness direction of the corrugated sheet 1 of 22 mm. The first insertion portion 11 is connected to the right end of the main body 13. The second insertion portion 12 is connected to the left end of the main body 13. The first insertion portion 11 of one corrugated sheet 1 is inserted into the second insertion portion 12 of another corrugated sheet 1, forming a support cavity 1A enclosed by side walls. The extension direction of the side walls of the support cavity 1A is consistent with the extension direction of the corrugated sheet 1. A portion of the side walls of the support cavity 1A is formed by overlapping a portion of the first insertion portion 11 and a portion of the second insertion portion 12.

[0101] The supporting cavity 1A formed between the two interlocking corrugated sheets 1 serves two purposes: firstly, it strengthens the connection and structural strength between the two corrugated sheets 1, thereby improving the reliability of the connection between them; secondly, it helps prevent external contaminants (such as rainwater and dust) from eroding the connection points of the corrugated sheets 1, maintaining connection reliability and thus extending the service life of the corrugated sheets 1. Furthermore, the interlocking assembly of the corrugated sheets 1 reduces construction difficulty and improves installation efficiency.

[0102] like Figure 1 As shown, the main body 13 includes a first outer wall 131, a second outer wall 132, and two diagonal ribs. The first outer wall 131 and the second outer wall 132 are respectively disposed at a first end and a second end along the thickness direction of the corrugated sheet 1. The two diagonal ribs are located between the first outer wall 131 and the second outer wall 132, and are symmetrically and spaced apart along the thickness direction of the corrugated sheet 1. The first outer wall 131 is configured as an arched wall that arches toward the side away from the second outer wall 132. The cross-section of the arched wall perpendicular to the corrugated sheet 1 is, for example, trapezoidal or arc-shaped.

[0103] like Figure 1As shown, the first insertion portion 11 includes a first insertion groove 11a. The first insertion groove 11a includes a first bottom wall 111, a first side wall 112, a second side wall 113, and a rib 114. The first bottom wall 111 is connected to the right side of the main body portion 13 and extends in a direction perpendicular to the second outer wall 132. The first side wall 112 and the second side wall 113 are respectively connected to a first end and a second end of the first bottom wall 111 along the thickness direction of the corrugated plate 1. The first side wall 112 extends obliquely from the right end of the first outer wall 131 toward a direction away from the main body portion 13. The second side wall 113 extends to the right from the right end of the second outer wall 132, and its end away from the main body portion 13 includes a first mating portion 1131. A first slot is formed on the side of the first insertion groove 11a away from the main body portion 13. Rib 114 is located between the first side wall 112 and the second side wall 113 of the first insertion groove along the thickness direction of the corrugated plate 1, and is arranged parallel to the second side wall 113 of the first insertion groove.

[0104] like Figure 1 and Figure 6 As shown, rib 114 and the first sidewall 112 of the first insertion slot form a first gap 11b. The dimension of the first gap 11b along the thickness direction of the corrugated sheet 1 is, for example, 2.2 mm. Rib 114 and the second sidewall 113 of the first insertion slot form a second gap 11c. Along the width direction of the corrugated sheet 1, the dimension of rib 114 is larger than the dimension of the first sidewall 112 of the first insertion slot and smaller than the dimension of the second sidewall 113 of the first insertion slot, and the dimension of the first sidewall 112 of the first insertion slot is smaller than the dimension of the second sidewall 113 of the first insertion slot. Along the width direction of the corrugated sheet 1, the dimension of the first sidewall 112 of the first insertion slot is, for example, 4.2 mm.

[0105] like Figure 1As shown, the second insertion portion 12 includes a second insertion groove 12a. The second insertion groove 12a includes a second bottom wall 12, a first side wall 122, and a second side wall 123. The second bottom wall 121 is connected to the left side of the main body portion 13 and extends in a direction perpendicular to the second outer wall 132. The first side wall 122 and the second side wall 123 are respectively connected to a first end and a second end of the second bottom wall 121 along the thickness direction of the corrugated plate 1. Along the width direction of the corrugated plate 1, the size of the first side wall 122 is larger than the size of the second side wall 123. The first side wall 122 is arranged parallel to the second outer wall 132. One end of the second side wall 123, which is connected to the second outer wall 132, extends from the left end of the second outer wall 132 to the left and is arranged parallel to the second outer wall 132. The end of the second sidewall 123 of the second insertion groove away from the main body 13 includes a second mating part 1231. The opening of the second insertion groove 12a faces away from the main body 13, and the side of the second insertion groove 12a away from the main body 13 forms a second opening.

[0106] like Figure 5 and Figure 6 As shown, the first gap 11b accommodates the end of the first sidewall 122 of the second insertion slot 12a that is inserted into the first insertion slot 11a therein, which is away from the main body 13. The size of the end of the first sidewall 122 of the second insertion slot that is away from the main body 13 is smaller than the size of the first gap 11b.

[0107] like Figure 5 and Figure 6 As shown, a second L-shaped groove for receiving the first mating part 1131 is formed on the side of the second mating part 1231 away from the first end in the thickness direction of the corrugated plate 1. The size of the second L-shaped groove along the thickness direction of the corrugated plate 1 is, for example, 1.5 mm. The portion of the second L-shaped groove parallel to the first sidewall 122 of the second insertion slot overlaps with the first mating part 1131 of the first insertion slot 11a, which is inserted into the second insertion slot 12a, to form an overlapping portion 31, and is located within the first groove opening. The size of the overlapping portion 31 formed by the first mating part 1131 and the second mating part 1231 along the width direction of the corrugated plate 1 is, for example, 3 mm.

[0108] like Figures 2 to 6 As shown, the mobile cold storage unit using corrugated sheets 1 includes a storage body 8, a fixing device 6, a first corrugated sheet assembly 101, and a second corrugated sheet assembly 102. The first corrugated sheet assembly 101 and the second corrugated sheet assembly 102 are respectively connected to the left and right sides of the exterior of the storage body 8. The first corrugated sheet assembly 101 and the second corrugated sheet assembly 102 are formed by sequentially inserting the same number of corrugated sheets 1 along the width direction of the corrugated sheets 1. The fixing device 6 fixes the second side wall 113 of the first insertion slot to the storage body 8.

[0109] The first corrugated plate assembly 101 and the second corrugated plate assembly 102, formed by the interlocking corrugated plates 1, are connected to the outside of the mobile cold storage body 8. The support cavity 1A formed after the two corrugated plates 1 are interlocked is conducive to forming at least two layers of support structure along the thickness direction of the corrugated plates 1 at the connection position of the two corrugated plates 1, which is conducive to strengthening the structural strength and load-bearing capacity of the corrugated plate assembly, thereby enhancing the protective ability of the corrugated plate assembly for the cold storage body 8.

[0110] like Figure 3 As shown, the tank body 8 includes a top cover 82, a waterproof membrane 83, a crossbeam 84, and a panel 85. The panel 85 is located on the side of the tank body 8. The top cover 82 is fixed by connecting with the waterproof membrane 83 and the crossbeam 84, ensuring the stability of the top cover 82.

[0111] like Figure 3 and Figure 4 As shown, the corrugated sheet 1 is an L-shaped corrugated sheet extending in an L-shape. The fixing device 6 includes rivet groups, each rivet group consisting of 4 rivets. The rivet groups are arranged in a one-to-one correspondence with the corrugated sheets 1. One rivet in the rivet group is used to fix the short side of the L-shaped corrugated sheet to the top cover plate 82, and the other 3 rivets in the rivet group are used to fix the long side of the L-shaped corrugated sheet to the panel 85. The three rivets are evenly spaced along the length of the corrugated sheet 1, which helps to avoid structural deformation or loosening due to uneven stress.

[0112] When assembling the corrugated board 1 with the warehouse body 8, the first corrugated board 1 is first laid in the corresponding position of the warehouse body 8. Then, the second side wall 113 of the first insertion slot of the first corrugated board 1 is connected to the warehouse body 8 through a fixing device. Next, the first side wall 122 of the second insertion slot of the second corrugated board 1 is inserted into the first interval 11b of the first corrugated board 1. At the same time, the first mating part 1131 of the first insertion slot 11a of the first corrugated board 1 and the second mating part 1231 of the second insertion slot 12a of the first corrugated board 1 are mated. This process is repeated to complete the assembly of a corrugated board assembly and its assembly with the warehouse body 8. The assembly process of other corrugated board assemblies and their assembly with the warehouse body 8 is similar.

[0113] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and not to limit them; although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this disclosure or equivalent substitutions can be made to some technical features, all of which should be covered within the scope of the technical solutions claimed in this disclosure.
