[0002] Cleanroom panels, as an important building material, are widely used in industries requiring extremely high cleanliness levels, such as healthcare, electronics manufacturing, and food processing. Cleanroom panels consist of an upper and lower box, and a core material. During production, the core material is first placed within the lower box, and then the upper box is snapped onto the lower box to form a composite panel.

DETAILED DESCRIPTION

[0046] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0047] It should be noted that, unless otherwise specified, the technical or scientific terms used in this application should have the common meanings understood by those skilled in the art to which this application belongs.

[0048] like Figure 1 As shown, embodiment 1 of the present application provides a composite board, comprising a core material (not shown in the figure) and two protective units 1;

[0049] The two protective units 1 are arranged relative to each other along a first direction, and the protective units 1 are formed by bending at least one plate body, and the protective unit 1 includes: a protective plate 11, two side plates 12 and two connecting components 13; the two side plates 12 are respectively connected to the two sides of the protective plate 11 along the second direction; the two connecting components 13 are spaced and relatively arranged between the two side plates 12, and each connecting component 13 is connected to one side plate 12; wherein, the connecting components 13 of the two protective units 1 are connected so that the two protective units 1 form a enclosure structure together, and the core material is arranged in the enclosure structure and adapts to the enclosure structure; the first direction is consistent with the thickness direction of the protective plate 11, and the second direction is consistent with the width direction of the protective plate 11.

[0050] Specifically, the core material is used to provide one or more functions, and the specific function of the core material can be selected based on the actual application scenario of the composite panel 100. For example, the core material can have thermal insulation, sound insulation, or fire protection functions. Thermal insulation materials can include rock wool, polyurethane foam, etc.; sound insulation materials can include sound-absorbing cotton or sound insulation felt; and fire protection materials can include mineral wool or glass magnesium board. When the core material has multiple functions, it can be composed of a combination of various materials to meet the needs of different application scenarios.

[0051] The shape of the core material matches the shape of the enclosure structure to ensure that it can be smoothly placed in the enclosure structure; the size of the core material matches the size of the enclosure structure so that the core material can fit the inner wall of the enclosure structure, thereby ensuring a good fixing effect. During assembly, the core material can slide into the enclosure structure along the third direction, which is easy to install and easy to operate. The third direction is consistent with the length direction of the protective plate 11. The surface of the core material can be coated with a thermosetting adhesive; and / or, the inner wall of the enclosure structure can be coated with a thermosetting adhesive to achieve bonding between the core material and the enclosure structure, ensure the stability of the connection between the two, and prevent the core material from shifting. Thermosetting adhesives have the characteristics of weak viscosity at room temperature, and will quickly solidify and enhance viscosity after heating to ensure smooth sliding of the core material. Thermosetting adhesives can be selected from epoxy resins or polyurethanes, etc.

[0052] The protective unit 1 provides physical protection for the core material to prevent external impact, extrusion or other mechanical damage, while increasing the rigidity and stability of the composite panel. The protective plate 11 and the two side panels 12 can be connected by welding or bonding; alternatively, the protective plate 11 and the two side panels 12 can be formed as one piece; the side panels 12 and the connecting assembly 13 can be welded or bonded; alternatively, the side panels 12 and the connecting assembly 13 can be formed as one piece. In order to simplify the production process and improve the strength and stability of the protective unit 1, the protective unit 1 can be formed by cold bending a piece of plate, and the conveyed plate is extruded by a forming roller provided on the conveying mechanism to be bent into the desired shape. The design and arrangement of the forming rollers can be adjusted according to the requirements of the final product to ensure bending accuracy and consistency. The plate can be made of steel plate or aluminum plate, etc., to be suitable for applications requiring high strength and durability.

[0053] The protective plate 11 of the protective unit 1 can be perpendicular to the two side plates 12, forming a stable frame 211 structure. The connecting component 13 can be plate-shaped, and the two connecting components 13 of the protective unit 1 are spaced apart along the second direction so that one core material can be simultaneously attached to two protective units 1; the two connecting components 13 can be directly opposite each other along the second direction to enhance the clamping force on the core material, prevent the core material from shifting or deforming during use, and ensure the stability and safety of the core material. The two protective units 1 can be the same size, and the connecting components 13 of the two protective units 1 can be connected by bonding or snapping.

[0054] In the composite panel provided in Example 1 of the present application, since each protective unit 1 is formed by bending at least one plate body, the number of components and assembly steps required for traditional production are reduced, the production process is simplified, and production costs are reduced. Furthermore, the structure formed by bending at least one plate body has high strength and stability, thereby enhancing the protective effect of the core material.

[0055] The protective plate 11 and the side plate 12 provide protection for the surface of the composite panel, thereby improving the impact resistance of the composite panel; since the two connecting components 13 are spaced and relatively arranged between the two side panels 12, when the two protective units 1 are connected through the connecting component 13, the formed enclosure structure not only provides comprehensive protection for the core material, but also provides a stable clamping force for the core material through the connecting component 13, effectively preventing the core material from shifting or deforming during use, thereby ensuring the stability and safety of the core material; and, the cooperation between the connecting component 13 and the core material realizes the locking of the two protective units 1 along the first direction, thereby improving the structural integrity of the entire composite panel.

[0056] like Figure 1 、 Figures 3 to 5 As shown, in some embodiments, the connection component 13 includes:

[0057] a first connecting plate 131 , spaced apart from and opposite to the protective plate 11 ;

[0058] Second connecting plates 132, where the first connecting plate 131 is connected to the side plates 12 and the second connecting plates 132 on both sides along the second direction respectively; the side plates 12 and the second connecting plates 132 are located on both sides of the first connecting plate 131 along the first direction respectively;

[0059] The surface connection of the second connecting plates 132 of the two protection units 1 enables the connecting components 13 of the two protection units 1 to jointly form an assembly space 14 .

[0060] Specifically, the side panel 12, the first connecting panel 131 and the second connecting panel 132 can be welded; or, in order to simplify the production process, reduce the assembly steps, and improve the strength and stability of the connecting component 13, the side panel 12, the first connecting panel 131 and the second connecting panel 132 can be integrally formed.

[0061] The first connecting plates 131 of the two connecting assemblies 13 of each protective unit 1 are spaced apart and opposite to each other along the second direction. The first connecting plates 131 of the two connecting assemblies 13 of each protective unit 1 can be directly opposite to each other along the second direction to enhance the clamping force on the core material. The second connecting plates 132 of the two connecting assemblies 13 of each protective unit 1 are spaced apart and opposite to each other along the second direction. The second connecting plates 132 of the two connecting assemblies 13 of each protective unit 1 can be directly opposite to each other along the second direction to enhance the clamping force on the core material.

[0062] The first connecting plates 131 of the two protection units 1 are spaced apart and face each other along the first direction.

[0063] The first surfaces of the second connecting plates 132 of the two connecting components 13 of one protective unit 1, which are opposite to each other, can be respectively connected to the second surfaces of the second connecting plates 132 of the two connecting components 13 of the other protective unit 1, which are opposite to each other. That is, the two protective units 1 have the same structure, but the spacing between the two connecting components 13 of the two protective units 1 is slightly different, so that the other protective unit 1 can be snapped onto the one protective unit 1 to simplify the installation process of the two.

[0064] The assembly space 14 is used to place the assembly components 200 when multiple composite panels 100 are spliced ​​together, so as to facilitate the connection and fixation between the composite panels 100 and improve the installation efficiency.

[0065] like Figure 1 、 Figure 3 and Figure 5 As shown, in some embodiments, the connection component 13 further includes:

[0066] A first locking portion (not shown in the figure), configured on the second connecting plate 132 of one of the protection units 1;

[0067] A second locking portion (not shown in the figure) is configured on the second connecting plate 132 of the other protection unit 1, and the second locking portion is adapted to the first locking portion to achieve locking.

[0068] Specifically, the first locking portion may be a first magnetic member, which may be embedded in the first surface of the second connecting plate 132 of one protective unit 1. The second locking portion may be a second magnetic member, which may generate a magnetic force with the first magnetic member, and the second magnetic member may be embedded in the second surface of the second connecting plate 132 of the other protective unit 1. The first magnetic member may be a permanent magnet; the second magnetic member may be a permanent magnet, or, when the second connecting plate 132 is a steel plate, the second connecting plate 132 may form a second magnetic member to ensure that the two second connecting plates 132 are tightly fitted after being connected, thereby enhancing the stability of the connection. The first magnetic member and the second magnetic member can generate a magnetic force, thereby ensuring the stability of the connection between the second connecting plates 132 of the two protective units 1.

[0069] like Figure 1 、 Figure 3 and Figure 5 As shown, in some embodiments, the second connecting plate 132 of one of the protective units 1 has a groove (not shown in the figure), and the second connecting plate 132 of the other protective unit 1 has a protrusion (not shown in the figure) adapted to the groove, the groove forms the first locking portion, and the protrusion forms the second locking portion.

[0070] Specifically, the grooves and protrusions can be machined using CNC machines or stamping. The shapes and sizes of the protrusions and grooves are identical to ensure a tight fit. The number of grooves can be one or more. When there are multiple grooves, the multiple second grooves can be evenly distributed to enhance the stable connection between the second connecting plates 132 of the two protective units 1. The number and position of the protrusions can be specifically designed based on the grooves.

[0071] like Figure 1 、 Figure 3 and Figure 5 As shown, in some embodiments, the first connecting plate 131 is parallel to the protective plate 11 ; the second connecting plate 132 is parallel to the side plate 12 ; and the inner wall of the assembly space 14 is used to fit with the assembly component 200 .

[0072] Specifically, by arranging the first connecting plate 131 parallel to the protective plate 11 and the second connecting plate 132 parallel to the side plate 12, and utilizing the inner wall of the assembly space 14 to mate with the assembly component 200, that is, the assembly component 200 is used to mate with adjacent composite panels 100 along the first direction and / or the second direction, ensuring the flatness and stability of multiple composite panels 100 during installation, not only improving the tightness and stability of the connection, but also simplifying the installation process and enhancing the overall performance of the composite panels 100. The assembly component 200 can be made of Zhongzi aluminum 2.

[0073] like Figure 1 、 Figures 3 to 5 As shown, in some embodiments, the two side panels 12 of the protective unit 1 are bent toward each other to form a first assembly channel 15, and the first assembly channel 15 is connected to the assembly space 14, and the first assembly channel 15 is used to fit with the assembly component 200.

[0074] Specifically, the first assembly channel 15 is located between the protective plate 11 and the first connecting plate 131. The side panels 12 can be bent inwardly using a cold roll forming technique to form the first assembly channel 15. The assembly component 200 can be attached to the first assembly channel 15 along the first direction and / or the second direction, thereby increasing the attachment area of ​​the assembly component 200 to the adjacent composite panel 100, improving the tightness, stability, and flatness of the composite panel 100 during installation, simplifying the installation process, and enhancing the overall performance of the composite panel 100.

[0075] In some embodiments, the core material comprises:

[0076] Rock wool, adapted to the enclosure structure;

[0077] A glass magnesium board is arranged on the first surface of the rock wool, and the glass magnesium board is adapted to the enclosure structure; or, the size of the glass magnesium board along the second direction is less than or equal to the minimum size of the enclosure structure along the second direction.

[0078] Specifically, the rock wool and the glass magnesium board can be bonded or mechanically connected (for example, by rivets or self-tapping screws). The number of layers of rock wool and the number of layers of glass magnesium board can be specifically selected according to the actual application scenario. When the glass magnesium board is adapted to the enclosure structure, that is, the core material as a whole is adapted to the enclosure structure, due to the brittleness of the glass magnesium board, the core material can slide into the enclosure structure along the third direction; when the size of the glass magnesium board along the second direction is less than or equal to the minimum size of the enclosure structure along the second direction; because the rock wool is relatively soft, the core material can be grasped by a grasping device at this time, and the core material can be stuffed into a protective component along the first direction, and then another protective component is fastened to achieve automated assembly. When the glass magnesium board is located between the two side panels 12, the missing part of the glass magnesium board can be bonded with rock wool to fit the enclosure structure to achieve complete filling, thereby improving the overall stability and strength of the composite panel 100.

[0079] Example 2

[0080] like Figure 2 As shown, embodiment 2 of the present application provides a splicing body, including:

[0081] Multiple composite panels 100 according to embodiment 1;

[0082] The assembly component 200 is used to connect a plurality of the composite panels 100 .

[0083] Specifically, during the production process, the formed composite panels 100 can be cut into desired sizes so that multiple composite panels 100 can be spliced ​​into a spliced ​​body of desired size and shape. The assembly components 200 can be made of buckles or the like to achieve efficient splicing and a stable structure.

[0084] When the splicing body of the present application is installed on the wall, in order to ensure the flatness of the splicing body, Figure 2 、 Figure 3 and Figure 6 As shown, the composite panel 100 may have an assembly space 14 and a first assembly channel 15 communicating with each other, and the assembly spaces 14 of adjacent composite panels 100 along the second direction face each other, and the first assembly channels 15 of adjacent composite panels 100 along the second direction face each other.

[0085] Assembly assembly 200 includes an assembly member 21, which may comprise a frame 211, a first assembly plate 212, and a second assembly plate 213. Frame 211 has a U-shaped cross-section and is formed from four plates connected end-to-end to achieve a lightweight design. First assembly plate 212 and second assembly plate 213 face each other along a first direction and are respectively connected to the outer walls of frame 211. Both sides of frame 211 along the second direction mate with the inner walls of assembly space 14, while at least one side of frame 211 along the first direction mates with the inner wall of assembly space 14.

[0086] The first assembly plate 212 is fully or partially aligned with the inner wall of the first assembly channel 15 along the second direction, and the second assembly plate 213 is fully or partially aligned with the inner wall of the first assembly channel 15 along the second direction to improve the flatness of the composite panel 100 after connection. To facilitate the installation of the assembly member 21, the first assembly plate 212 may be partially raised on both sides in the second direction to form raised portions, which are aligned with the inner wall of the first assembly channel 15 along the second direction. The structure of the second assembly plate 213 can be similar to that of the first assembly plate 212.

[0087] The spliced ​​body provided in Example 2 of the present application includes the composite panel 100 provided in Example 1. Since each protective unit 1 of the composite panel 100 is formed by bending at least one plate, the number of components and assembly steps required for traditional production are reduced, the production process is simplified, and production costs are reduced. Furthermore, the structure formed by bending at least one plate has high strength and stability, thereby enhancing the protective effect on the core material.

[0088] The protective plate 11 and the side plate 12 provide protection for the surface of the composite panel 100, thereby improving the impact resistance of the composite panel 100; since the two connecting components 13 are spaced and relatively arranged between the two side panels 12, when the two protective units 1 are connected through the connecting component 13, the formed enclosure structure not only provides comprehensive protection for the core material, but also provides a stable clamping force for the core material through the connecting component 13, effectively preventing the core material from shifting or deforming during use, thereby ensuring the stability and safety of the core material; and, the cooperation between the connecting component 13 and the core material realizes the locking of the two protective units 1 along the first direction, thereby improving the structural integrity of the entire composite panel 100.

[0089] When the splicing body of the present application is hoisted on the ceiling of a building, in order to facilitate the hoisting of the splicing body, Figure 4 and Figure 5 As shown, in some embodiments, the side panels 12 of one protective unit 1 of adjacent composite panels 100 are in contact with each other; and the side panels 12 of another protective unit 1 of adjacent composite panels 100 are spaced apart along the second direction to form a second assembly channel.

[0090] like Figure 4 、 Figure 5 and Figure 7 As shown, in some embodiments, the assembly component 200 includes:

[0091] The center-character aluminum 2 is located in the second assembly channel, and the center-character aluminum 2 is fitted with the second assembly channel on both sides along the second direction; the center-character aluminum 2 is fitted with the connecting component 13 of another protective unit 1 of the adjacent composite panel 100 along the first direction, and part of the center-character aluminum 2 extends out of the second assembly channel to achieve lifting.

[0092] Specifically, the first assembly channel 15 is located between the second assembly channel and the assembly space 14, and the three are connected to each other. The central aluminum 2 can include an assembly part 21, a wing plate 22 and a connector 23. The first assembly plate 212 of the assembly part 21 can extend into the second assembly channel and fit with the inner wall of the second assembly channel along the second direction. The wing plate 22 is opposite to the frame 211 along the first direction. The first surface of the wing plate 22 is vertically connected to the first assembly plate 212, and the first assembly plate 212 is located in the middle of the first surface of the wing plate 22 along the second direction. The second surface of the wing plate 22 is connected to the connector 23, and the connector 23 is used for hoisting.

[0093] During installation, the connector 23 can be first connected to the building ceiling to achieve the hoisting of the center aluminum 2. The composite panel 100 is then inserted between two adjacent center aluminum 2, followed by the next composite panel 100, until all the panels are connected. The edge composite panels 100 can be bonded to the building to ensure the stability of the overall structure.

[0094] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
