Description

Technical Field

[0001] This application relates to the field of cryogenic storage and transportation equipment technology, and in particular to a corrugated plate filling structure and its installation method. Background Technology

[0002] In membrane-type containment systems for liquefied natural gas (LNG) ships or cryogenic storage tanks, the back of the corrugated metal sheets is usually filled with supporting material to absorb thermal expansion and contraction and support the liquid cargo load. However, the existing corrugated sheet filling operation mainly adopts the method of on-site assembly of individual parts. Construction workers need to manually insert the independent transverse and longitudinal filling blocks one by one into the intersection of the corrugated grooves. This method is not only cumbersome and inefficient, but also prone to positioning deviations at complex corrugated intersections due to the different shapes of the individual filling parts. This can lead to loosening, misalignment, or even detachment during subsequent sheet hoisting, transportation vibration, or cryogenic contraction, affecting the construction quality and operational safety of the containment system. Summary of the Invention

[0003] In order to improve the shortcomings of the existing technology of corrugated plate filling operation, which uses the method of assembling loose parts on site, resulting in low construction efficiency, high labor costs, and easy occurrence of positioning deviation, loosening and falling off of filling parts, thus affecting the construction quality and operational safety of the enclosure system, this application provides a corrugated plate filling structure and its installation method.

[0004] The corrugated plate filling structure and its installation method provided in this application adopt the following technical solution:

[0005] A corrugated sheet filling structure includes a corrugated sheet body, a transverse filling module inserted transversely on the corrugated sheet body, a longitudinal filling module inserted longitudinally on the corrugated sheet body and the transverse filling module, and a fastening and fixing component attached to the side wall of the corrugated sheet body, the transverse filling module and the longitudinal filling module.

[0006] The corrugated plate body is provided with transverse receiving grooves arranged in an array along the transverse direction and longitudinal receiving grooves arranged in an array along the longitudinal direction and intersecting and communicating with the transverse receiving grooves. The transverse filling module is inserted into the transverse receiving groove, and the transverse filling module is provided with a module avoidance mating groove at the intersection with the longitudinal receiving groove. The longitudinal filling module is inserted into the longitudinal receiving groove, and a part of the longitudinal filling module is embedded in the module avoidance mating groove of the transverse filling module, so that the transverse filling module and the longitudinal filling module form a fitting connection at the intersection.

[0007] By adopting the above technical solution, a stable cross-locking structure is formed at the grid intersection node of the corrugated plate body by utilizing the module avoidance and mating groove on the transverse filling module and the longitudinal filling module, and integrated encapsulation is achieved in conjunction with the tight fixing component. This application not only effectively restricts the relative displacement of the transverse filling module and the longitudinal filling module through physical deep embedding, ensuring the continuity of support, but also reduces installation detachment, enhances positioning accuracy, improves installation efficiency, and enhances the overall structural stability and impact resistance of the corrugated plate body back support system.

[0008] Preferably, both the transverse filling module and the longitudinal filling module are integrally formed structures.

[0009] By adopting the above technical solutions, not only is the overall shear strength of the components enhanced through the integrated molding process, but the physical interlocking in space also effectively prevents the modules from breaking and falling off under low temperature shrinkage and external impact, thereby improving the structural integrity and long-term operational stability of the corrugated plate body back support system.

[0010] Preferably, the fastening and fixing component is adhesive tape.

[0011] By adopting the above technical solution, adhesive tape is used as a fastening and fixing component. The fastening and fixing component is covered and pasted on the bottom surface of the horizontal and vertical filling modules and extends to the side wall of the corrugated plate body to achieve flexible sealing. This application utilizes the physical interlocking between modules to bear the main structural load and prevent low-temperature misalignment. At the same time, the lightweight and easy-to-operate characteristics of the adhesive tape complete the auxiliary pre-fixing. While effectively ensuring the connection reliability of the back support system of the corrugated plate body, it reduces the difficulty of on-site construction and improves the overall installation efficiency.

[0012] Preferably, the corrugated plate body is provided with a module limiting flange that is fixedly connected to the corrugated plate body and extends along the direction of insertion into the transverse receiving groove, and the transverse filling module is provided with module limiting grooves on both sides for the module limiting flange to be inserted.

[0013] By adopting the above technical solution, the module limiting protrusion integrated on the inner wall of the corrugated plate body and the module limiting grooves on both sides of the transverse filling module form a concave-convex nested linear guiding and locking structure. This application not only plays a precise guiding role during installation to avoid the transverse filling module from tilting, but also provides a normal constraint force perpendicular to the insertion direction after installation, effectively preventing the module from slipping out of the corrugated plate body due to its own weight, transportation vibration or low temperature shrinkage, thus improving the connection reliability and seismic performance of the overall structure.

[0014] Preferably, the longitudinal filling module includes a first soft layer, a second hard layer fixedly connected to the first soft layer, and a third soft layer fixedly connected to the second hard layer; the first soft layer, the second hard layer, and the third soft layer are integrally formed.

[0015] By adopting the above technical solution, the second rigid layer is located in the middle as a load-bearing frame; during the assembly process, the first soft layer located at the contact interface first undergoes adaptive deformation using its flexible characteristics to tightly adhere to the inner wall of the corrugated plate body; this application balances the needs of rigid support and flexible protection through a "soft, hard, soft" composite structure, which not only utilizes the second rigid layer to effectively transfer the liquid cargo load, but also utilizes the first soft layer as a buffer layer to absorb impact energy, avoiding local stress damage to the corrugated plate body caused by direct pressure from rigid materials, thereby improving the structural safety and service life of the enclosure system.

[0016] Preferably, the corrugated plate body is further provided with an insertion protrusion that is fixedly connected to the corrugated plate body and extends along the direction of insertion into the longitudinal receiving groove, and the longitudinal filling module is provided with limiting insertion grooves on both sides for insertion of the insertion protrusion.

[0017] By adopting the above technical solution, the interlocking longitudinal constraint system is formed by the insertion protrusion extending from the inner wall of the longitudinal receiving groove of the corrugated plate body and the limiting insertion groove adapted to the side wall of the longitudinal filling module. Deep mechanical engagement is achieved by pressing the longitudinal filling module in. This application increases the contact area and frictional resistance through the cooperation of the insertion protrusion and the limiting insertion groove, providing additional normal constraint force, effectively preventing the longitudinal filling module from loosening from the corrugated plate body under the vibration or low temperature shrinkage conditions of liquid cargo transportation, and improving the connection reliability and fatigue resistance of the internal support structure of the enclosure system.

[0018] Preferably, the limiting insertion groove includes a first slot disposed on both sides of the first soft layer, a second slot disposed on both sides of the second hard layer, and a third slot disposed on both sides of the third soft layer;

[0019] The insertion protrusion includes a first protrusion for insertion into the first slot, a second protrusion for insertion into the second slot, and a third protrusion for insertion into the third slot; the first protrusion, the second protrusion, and the third protrusion are arranged in an array along the depth direction of the longitudinal receiving groove.

[0020] By adopting the above technical solution, the array-type locking mechanism distributed along the depth direction increases the contact area and frictional resistance. This not only achieves targeted fixation of different material layers with different hardness, effectively preventing interlayer misalignment or peeling of the composite structure, but also enhances the pull-out resistance and overall connection rigidity of the longitudinal filling module in the depth direction, ensuring that each functional layer can maintain a stable structural position under complex stress conditions.

[0021] Preferably, the fastening and fixing assembly further includes fixing protrusions connected to the side wall of the corrugated plate body and arranged in an array, and fiberglass mesh cloth attached to the side wall of the corrugated plate body and sleeved around the fixing protrusions.

[0022] By adopting the above technical solution, the fiberglass mesh covers the filling area and is directly fitted onto the fixed protrusion through the mesh to form a composite mechanical anchor. This application achieves physical attachment and position locking by pressing the fiberglass mesh into the fixed protrusion, which enhances the shear resistance and peel strength of the encapsulation layer, effectively preventing edge warping, tearing or overall detachment caused by stress concentration due to alternating hot and cold temperatures in low-temperature environments, and ensuring the long-term sealing and stability of the corrugated plate filling structure under harsh working conditions.

[0023] Preferably, the fixed protrusion is provided with an annular snap-fit ​​groove on its periphery, and the fiberglass mesh is inserted into the annular snap-fit ​​groove.

[0024] By adopting the above technical solution, the strong axial limiting effect provided by the annular snap-fit ​​groove effectively prevents the fiberglass mesh from slipping along the direction of the fixed protrusion, forming a stable embedded lock, and improving the peel strength and overall connection stability of the encapsulation layer under low temperature shrinkage and external tearing conditions.

[0025] Preferably, a method for installing a corrugated sheet filling structure, using the aforementioned corrugated sheet filling structure, further includes the following steps:

[0026] S1. The longitudinal filling module is embedded in the module avoidance groove of the transverse filling module to form a filling component prefabricated part;

[0027] S2. Align the pre-fabricated filling component with the transverse receiving groove and the longitudinal receiving groove of the corrugated plate body, and press it into the back space of the corrugated plate body as a whole.

[0028] S3. The corrugated plate body, the transverse filling module and the longitudinal filling module are fixedly connected by the fastening and fixing components.

[0029] By adopting the above technical solution, the prefabricated filling component is constructed by first embedding the longitudinal filling module into the module avoidance and mating groove of the transverse filling module, and then pressing the prefabricated filling component into the back of the corrugated plate body as a whole unit and sealing it with the fastening and fixing component. This application utilizes the structural interlocking of the prefabricated filling component to reduce the positioning difficulty and loosening during single-piece installation, reduce the difficulty of operation and time cost, and improve the installation efficiency and construction quality.

[0030] In summary, this application includes at least one of the following beneficial technical effects:

[0031] 1.

[0039] The following is in conjunction with the appendix Figures 1 to 3 This application will be described in further detail.

[0040] This application discloses a corrugated plate filling structure and its installation method. (Refer to...) Figure 1 A corrugated plate filling structure, in embodiment one, includes a corrugated plate body 1, a transverse filling module 2 inserted transversely on the corrugated plate body 1, a longitudinal filling module 3 inserted longitudinally on the corrugated plate body 1 and the transverse filling module 2 respectively, and a fastening and fixing component 4 attached to the side wall of the corrugated plate body 1, the transverse filling module 2 and the longitudinal filling module 3.

[0041] The corrugated plate body 1 is provided with transverse receiving grooves 5 arranged in an array along the transverse direction and longitudinal receiving grooves 6 arranged in an array along the longitudinal direction and intersecting and communicating with the transverse receiving grooves 5. The transverse filling module 2 is inserted into the transverse receiving groove 5, and the transverse filling module 2 is provided with a module avoidance mating groove 7 at the intersection with the longitudinal receiving groove 6. The longitudinal filling module 3 is inserted into the longitudinal receiving groove 6, and a part of the longitudinal filling module 3 is embedded in the module avoidance mating groove 7 of the transverse filling module 2, so that the transverse filling module 2 and the longitudinal filling module 3 form a fitting connection at the intersection.

[0042] The corrugated plate body 1 of this application constructs a three-dimensional grid space through orthogonally distributed transverse receiving grooves 5 and longitudinal receiving grooves 6 on its surface. The transverse filling module 2 is completely embedded inside the transverse receiving groove 5, and the longitudinal filling module 3 is provided with an installation channel through the module clearance mating groove 7. When the longitudinal filling module 3 is pressed into the longitudinal receiving groove 6, the longitudinal filling module 3 is directly fitted into the module clearance mating groove 7, thereby forming a cross-locking structure in space between the transverse filling module 2 and the longitudinal filling module 3. Then, the fastening and fixing component 4 is connected across the side wall of the corrugated plate body 1 and the transverse filling module 2 and the longitudinal filling module 3. To the surface of the filling module 3; this application first positions the transverse filling module 2 in the transverse receiving groove 5, and then aligns the longitudinal filling module 3 with the module avoidance mating groove 7 for normal pressing and achieves structural interlocking, and performs surface encapsulation by the sticking and fixing component 4; this application not only restricts the relative displacement of the transverse filling module 2 and the longitudinal filling module 3 at the corrugated intersection point through physical fitting, ensuring the continuity of support, but also achieves integrated fixing of prefabricated parts by combining with the sticking and fixing component 4, improving installation efficiency, reducing detachment, and enhancing the structural stability and impact resistance of the back support of the corrugated plate body 1.

[0043] The corrugated plate body 1 has transverse corrugations and longitudinal corrugations that bulge to one side and form an internal space, thereby defining the transverse receiving groove 5 and the longitudinal receiving groove 6 respectively. The transverse receiving groove 5 and the longitudinal receiving groove 6 are arranged intersectingly. The transverse filling module 2 and the longitudinal filling module 3 are preferably rigid polyurethane foam.

[0044] Furthermore, such as Figure 1 As shown, both the transverse filling module 2 and the longitudinal filling module 3 of this application are integrally formed structures, forming a deep interlocking connection with a cross-shaped locking at the corrugation intersection. In this application, the transverse filling module 2 is first positioned and implanted into the transverse receiving groove 5, and then the longitudinal filling module 3 is pressed into the longitudinal receiving groove 6 in the vertical direction and aligned with the embedded module avoidance mating groove 7 to complete the mechanical engagement. The integrally formed structure of the transverse filling module 2 and the longitudinal filling module 3 of this application enhances the overall shear strength. With the spatial interlocking, it effectively prevents the modules from breaking and falling off under low temperature shrinkage or external impact, and improves the structural integrity and long-term operational stability of the back support system of the corrugated plate body 1.

[0045] Furthermore, such as Figure 1As shown, the fastening and fixing component 4 in this application is preferably adhesive tape. The adhesive tape, serving as the fastening and fixing component 4, covers and adheres to the bottom surfaces of the transverse filling module 2 and the longitudinal filling module 3, extending to the side wall of the corrugated plate body 1 to achieve flexible sealing. First, the transverse filling module 2 is positioned and implanted into the transverse receiving groove 5. Then, the longitudinal filling module 3 is pressed into the longitudinal receiving groove 6 along the normal direction and aligned with the embedded module avoidance mating groove 7 to complete mechanical engagement. Finally, adhesive tape is used to bridge and adhere the modules to limit their normal detachment. This application utilizes the physical interlocking between modules to bear the main structural load and limit the function, effectively preventing misalignment caused by low-temperature shrinkage. At the same time, the lightweight and easy-to-operate characteristics of the adhesive tape assist in completing the pre-fixation, reducing the difficulty of on-site construction and improving the overall installation efficiency and connection reliability of the back support system of the corrugated plate body 1.

[0046] Specifically, such as Figure 2 As shown in Embodiment 2, the corrugated plate body 1 of this application is provided with a module limiting flange 11. The module limiting flange 11 extends inward on the inner wall of the transverse receiving groove 5. The transverse filling module 2 has corresponding module limiting grooves 21 on both side walls that are adapted to the shape of the module limiting flange 11, thereby forming a linear guiding and locking structure with concave and convex nesting. During the process of pushing the transverse filling module 2 into the transverse receiving groove 5, the module limiting flange 11 slides in and is completely embedded in the module limiting groove 21 until the module is installed in place. This application utilizes the mechanical cooperation between the module limiting flange 11 and the module limiting groove 21 to provide precise guidance during installation, preventing the transverse filling module 2 from becoming skewed. On the other hand, after installation, it provides a normal constraint force perpendicular to the insertion direction, effectively preventing the transverse filling module 2 from slipping out of the corrugated plate body 1 due to its own weight, transportation vibration, or low temperature shrinkage, thereby improving the connection reliability and seismic performance of the overall structure.

[0047] The module limiting flange 11 is preferably a stamped reinforcing rib or a pre-welded and bonded anchor.

[0048] More specifically, such as Figure 2As shown, the longitudinal filling module 3 of this application includes a first soft layer 31, a second hard layer 32, and a third soft layer 33, and is an integrally formed structure. The internal connection relationship of the longitudinal filling module 3 is that materials of different moduli are solidified into a single entity through co-extrusion or molding processes. The second hard layer 32 is located in the middle as a load-bearing frame, and the first soft layer 31 and the third soft layer 33 with elasticity are respectively fused and connected on both sides. In this application, the integral longitudinal filling module 3 is first aligned and pressed into the longitudinal receiving groove 6. The first soft layer 31 located at the contact interface first undergoes adaptive deformation due to its flexible characteristics to tightly adhere to the inner wall of the corrugated plate body 1. Then, the rigid second hard layer 32 follows into place to establish a stable support path. In this application, the second hard layer 32 provides sufficient compressive strength to effectively transfer the liquid cargo load, while the first soft layer 31 is used as a buffer layer to effectively absorb the swaying impact energy and prevent local stress damage or cracking of the corrugated plate body 1 caused by direct pressure from the hard material, thereby improving the structural safety and service life of the enclosure system.

[0049] The hardness of the second hard layer 32 is greater than that of the first soft layer 31 and the third soft layer 33, respectively.

[0050] In addition, such as Figure 2 As shown, the corrugated plate body 1 of this application is also provided with an insertion protrusion 12. The insertion protrusion 12 extends into the groove on the inner wall of the longitudinal receiving groove 6. The two side walls of the longitudinal filling module 3 are respectively provided with limiting insertion grooves 34 that are adapted to the shape of the insertion protrusion 12, thus forming a longitudinal constraint system with interlocking concave and convex shapes. In this application, the longitudinal filling module 3 is first aligned with the longitudinal receiving groove 6 and pressed in along the depth direction. During this process, the insertion protrusion 12 slides in and is completely embedded in the limiting insertion groove 34 until the module is installed in place. This application utilizes the deep mechanical engagement between the insertion protrusion 12 and the limiting insertion groove 34 to effectively increase the contact area and frictional resistance between the two, providing additional normal constraint force for the longitudinal filling module 3, preventing the longitudinal filling module 3 from loosening from the corrugated plate body 1 under the conditions of vibration or low temperature shrinkage during liquid cargo transportation, and improving the connection reliability and fatigue resistance of the internal support structure of the enclosure system.

[0051] The insertion flange 12 is preferably a stamped reinforcing rib or a pre-welded and bonded anchor.

[0052] And, as Figure 2As shown, the insertion flange 12 of this application includes a first protrusion 121, a second protrusion 122, and a third protrusion 123; the limiting insertion groove 34 includes a first slot 341 located on both sides of the first soft layer 31, a second slot 342 located on both sides of the second hard layer 32, and a third slot 343 located on both sides of the third soft layer 33, which respectively form a one-to-one embedded locking engagement with the first protrusion 121, the second protrusion 122, and the third protrusion 123 arranged in an array along the depth direction of the longitudinal receiving groove 6; this application presses the longitudinal filling module 3 into the longitudinal During the process of receiving the slot 6, the protrusions and slots corresponding to each level are aligned synchronously or gradually and multi-point engagement is achieved until they are completely fitted. This application refines the single plug-in constraint into a multi-level array-type locking distributed along the depth direction, which not only increases the contact area and frictional resistance, but also achieves targeted fixing of layers of different materials with different hardness, effectively preventing interlayer misalignment or peeling of the composite structure. It also enhances the pull-out resistance and overall connection rigidity of the longitudinal filling module 3 in the depth direction, ensuring that each functional layer can maintain a stable structural position under complex stress conditions.

[0053] Furthermore, such as Figure 2 As shown, in another embodiment of this application, the fastening and fixing component 4 further includes fixing protrusions 41 and fiberglass mesh 42. Multiple fixing protrusions 41 extend outward along the sidewall surface of the corrugated plate body 1 and are arranged in an array. The fiberglass mesh 42, as an encapsulation material, covers the surface of the corrugated plate body 1 and the internal filling module, and the flexible mesh of the fiberglass mesh 42 is directly fitted around the fixing protrusions 41, thereby forming a composite mechanical anchoring connection. In this application, the fiberglass mesh 42 is first laid flat, tensioned, and covers the filling area, and then the mesh of the fiberglass mesh 42 is aligned with the array of fixing protrusions 41. The columns are pressed in the normal direction to make the fixing protrusions 41 pass through the mesh and achieve position locking by interference fit or auxiliary bonding. This application uses the physical connection between the fixing protrusions 41 and the fiberglass mesh 42 to enhance the shear resistance and peel strength of the fastening component 4, and enhance the dimensional stability and tensile strength of the fiberglass mesh 42 in low temperature environment. With the array-type gripping of the fixing protrusions 41, it effectively prevents the edge lifting, tearing or overall detachment of the encapsulation layer due to the stress concentration of alternating hot and cold temperatures, and ensures the long-term sealing and stability of the corrugated plate filling structure under harsh working conditions.

[0054] The fixed protrusion 41 is preferably a stamped reinforcing rib or a pre-welded and bonded anchor.

[0055] Furthermore, such as Figure 2As shown, the fixed protrusion 41 of this application is provided with an annular locking groove 411 on its periphery. The fiberglass mesh 42 is sleeved on the fixed protrusion 41 using the mesh gaps, and the fiber bundles at the edge of the mesh are directly embedded and locked inside the annular locking groove 411, thus forming a three-dimensional mechanical anchor point. In this application, the fiberglass mesh 42 is first laid flat and aligned, and pressure is applied so that the mesh bundles overcome the tension and pass over the top of the fixed protrusion 41. Then, the fiber elasticity is used to slide into the annular locking groove 411 to complete self-locking. The structural limiting effect of the annular locking groove 411 effectively prevents the fiberglass mesh 42 from slipping off along the axial direction of the fixed protrusion 41, and improves the peel strength and connection stability of the encapsulation layer under low temperature shrinkage and external tearing conditions.

[0056] Specifically, such as Figure 3 As shown, a method for installing a corrugated plate filling structure, which uses a corrugated plate filling structure, also includes the following steps:

[0057] S1. Embed the longitudinal filling module 3 into the module clearance and mating groove 7 of the transverse filling module 2 to form a filling component prefabricated part;

[0058] S2. Align the prefabricated filling component with the transverse receiving groove 5 and the longitudinal receiving groove 6 of the corrugated plate body 1, and press it into the back space of the corrugated plate body 1 as a whole.

[0059] S3. Secure the corrugated plate body 1, the transverse filling module 2, and the longitudinal filling module 3 by attaching the fastening and fixing component 4.

[0060] This application first assembles the prefabricated filling component by embedding the longitudinal filling module 3 into the module clearance groove 7 of the transverse filling module 2. Then, the prefabricated filling component is transported as a whole unit and aligned with the back opening of the corrugated plate body 1. It is then pressed into place in one go along the normal direction, and the connection is covered by the fastening fixing component 4. This application reduces the positioning difficulty and loosening during the installation of individual components by utilizing the structural interlocking of the prefabricated filling component itself, thereby reducing the operation time and difficulty, and improving the installation efficiency and construction quality.

[0061] The implementation principle of the corrugated plate filling structure and its installation method in this application is as follows:

[0062] A corrugated sheet filling structure comprises a corrugated sheet body 1 with orthogonally distributed transverse and longitudinal receiving grooves 5 and 6 forming a three-dimensional grid space. A transverse filling module 2 is completely embedded within the transverse receiving groove 5, and a module clearance fitting groove 7 provides an installation channel for a longitudinal filling module 3. When the longitudinal filling module 3 is pressed into the longitudinal receiving groove 6, it directly fits into the module clearance fitting groove 7, thus forming a mutually interlocking cross-shaped locking structure between the transverse and longitudinal filling modules 2 and 3. A fastening and fixing component 4 then bridges the sidewall of the corrugated sheet body 1 and the transverse filling modules. 2. Surface of longitudinal filling module 3; In this application, the transverse filling module 2 is first positioned in the transverse receiving groove 5, and then the longitudinal filling module 3 is aligned with the module avoidance mating groove 7 and pressed in normally to achieve structural interlocking. The surface is encapsulated by the fastening fixing component 4. This application not only restricts the relative displacement of the transverse filling module 2 and the longitudinal filling module 3 at the corrugated intersection point through physical fitting, ensuring the continuity of support, but also achieves integrated fixing of prefabricated parts by combining the fastening fixing component 4, which improves installation efficiency, reduces detachment, and enhances the structural stability and impact resistance of the back support of the corrugated plate body 1.

[0063] During the process of pushing the transverse filling module 2 into the transverse receiving groove 5, the module limiting protrusion 11 slides in and is fully embedded in the module limiting groove 21 until the module is installed in place. This application utilizes the mechanical cooperation between the module limiting protrusion 11 and the module limiting groove 21 to provide precise guidance during installation, preventing the transverse filling module 2 from becoming skewed. On the other hand, after installation, it provides a normal constraint force perpendicular to the insertion direction, effectively preventing the transverse filling module 2 from slipping out of the corrugated plate body 1 due to its own weight, transportation vibration, or low temperature shrinkage, thereby improving the connection reliability and seismic performance of the overall structure.

[0064] A method for installing a corrugated sheet filling structure involves first assembling the prefabricated filling component by embedding the longitudinal filling module 3 into the module clearance groove 7 of the transverse filling module 2. Then, the prefabricated filling component is transported as a whole unit and aligned with the back opening of the corrugated sheet body 1, and pressed into place in one go along the normal direction. The connection is then covered by the fastening fixing component 4. This application utilizes the structural interlocking property of the prefabricated filling component itself to reduce the positioning difficulties and loosening during single-piece installation, reduce the operation time and difficulty, and improve the installation efficiency and construction quality.

[0065] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
