[0046] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0047] The specific technical features described in the various embodiments in the detailed implementation can be combined in various ways without contradiction. For example, different implementation methods can be formed by combining different specific technical features. In order to avoid unnecessary repetition, the various possible combinations of the specific technical features in this utility model will not be described separately.

[0048] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0049] Additionally, it should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

It should be understood that the directional descriptions such as "above," "below," "inside," and "outside" refer to the orientation under normal use conditions.

[0050] In the following specific embodiments, the metal panels in the metal exterior wall can be any metal capable of providing protection, such as iron, aluminum, or an alloy of multiple metals. The metal panels are fixed to the wall using a dry-hanging method, a wet-hanging structure, or a combination of both. Depending on the specific structure of the metal exterior wall, it can achieve various functions. For example, using a thermal insulation layer can achieve thermal insulation or heat preservation; using a vacuum insulation layer can achieve sound insulation; and adding wall decorations can enhance the building's aesthetics. These structures can also be combined to achieve multiple functions simultaneously. The following examples illustrate different components and the overall structure of the metal exterior wall.

[0051] First, combine Figure 1 Describe the usage environment of metal exterior wall structures, such as Figure 1 As shown, the metal exterior wall structure includes exterior wall fixing nodes 10, metal plates 20, and wall 30. Wall 30 is the building's interior wall structure. The metal plates 20 are fixedly connected to wall 30 via exterior wall fixing nodes 10. Multiple metal plates 20 are arranged side-by-side to cover wall 30. Exterior wall fixing nodes 10 include connecting structures 100 and connecting plates 200. Connecting structures 100 are used for fixed connection to metal plates 20, and connecting plates 200 are used for fixed connection to wall 30. Simultaneously, the connecting structures 100 and connecting plates 200 are fixedly connected to securely connect the metal plates 20 to wall 30. Furthermore, the metal exterior wall structure also includes an infill layer 40, which fills... Layer 40 is fixed to metal plate 20 and infill layer 40 is located between metal plate 20 and wall 30. Metal composite wall panel is formed by infill layer 40 and metal plate 20, which can enable the metal exterior wall structure to have richer functions. For example, if infill layer 40 includes waterproof material, the metal exterior wall structure has waterproof function. For example, if infill layer 40 includes sound insulation material, the metal exterior wall structure has sound insulation function. For ease of explanation, the structure and function of metal composite wall panel are illustrated below with the example of infill layer 40 including thermal insulation material.

[0052] In some embodiments, such as Figure 2 As shown, the metal composite wall panel includes: a metal plate 20, a filler layer 40, and a support member 70. The filler layer 40 is fixed to the fixing surface of the metal plate 20, which is... Figure 1The metal plate 20 faces the outer surface of the wall 30. Depending on the material of the filling layer 40, it can perform different functions. For example, when the filling layer 40 includes thermal insulation material, it can improve the thermal insulation capacity of the exterior wall structure. For example, when the filling layer 40 includes sound-absorbing sponge material, it can improve the sound insulation capacity of the exterior wall structure. For example, when the filling layer 40 includes mortar and metal mesh, it can improve the structural strength of the metal plate 20, thereby improving the overall structural strength of the exterior wall structure; simultaneously, it supports... The component 70 is located within the filling layer 40 and is fixedly connected to the fixing surface of the filling layer 40. This can be understood as follows: on the basis of the filling layer 40 being directly fixed to the metal plate 20, the support component 70 is embedded in the filling layer 40 to fix the support component 70 to the filling layer 40 and simultaneously fix the support component 70 to the metal plate 20. Thus, the filling layer 40 is fixedly connected to the metal plate 20 through the support component 70. In other words, the support component 70 assists in connecting the filling layer 40 and the metal plate 20, thereby enabling the filling layer 40 to be more reliably fixedly connected to the metal plate 20.

[0053] Optionally, the filler layer 40 can be formed in any way, and the filler layer 40 can be combined with the support member 70 in any way. For example, the filler layer 40 is a rigid structure formed by extrusion sintering, which has a cavity for accommodating the support member 70. By embedding the support member 70 into the cavity, the combination of the support member 70 and the filler layer 40 can be achieved.

[0054] Optionally, the filler layer 40 is formed by casting. Before casting, the support member 70 is placed in the casting template. After the filler layer 40 is formed by casting, the support member 70 can be fixed inside the filler layer 40. At the same time, the end of the support member 70 used for fixed connection with the metal plate 20 is flush with the end face of the filler layer 40, so that the support member 70 can be fixedly connected to the metal plate 20 at the same time as the filler layer 40 can be fixedly connected to the metal plate 20.

[0055] This utility model provides a metal composite wall panel, which includes a metal plate and a filling layer fixed to a fixed surface of the metal plate. The fixed surface is located on one side of the metal plate in the thickness direction. By fixing the filling layer to the fixed surface of the metal plate, the metal composite wall panel can have the ability to insulate. At the same time, the metal composite wall panel also includes a support member, which is located in the filling layer and fixedly connected to the filling layer. It can be understood that, on the basis of the filling layer being directly fixed to the metal plate, the support member is embedded in the filling layer to fix the support member to the filling layer and simultaneously fix the support member to the metal plate. Thus, the filling layer is fixedly connected to the metal plate through the support member. That is, the support member assists in connecting the filling layer and the metal plate, so that the filling layer can be more reliably fixedly connected to the metal plate.

[0056] In some embodiments, such as Figure 3 As shown, the support member 70 includes a support body 71 and a fixing protrusion 72. The support body 71 extends along the thickness direction of the metal plate 20, meaning that by extending away from the metal plate 20, the support body 71 can penetrate deeper into the filling layer 40, thereby allowing for more thorough contact between the support body 71 and the filling layer 40. Simultaneously, the fixing protrusion 72 protrudes from the outer surface of the support body 71, creating an uneven structure on the outer surface of the portion of the support member 70 located within the filling layer 40. This further increases the contact area between the support member 70 and the filling layer 40, thereby increasing the reliability of the connection between the support member 70 and the filling layer 40. Optionally, as... Figure 3 As shown, there are multiple fixing protrusions 72, which are spaced apart along the thickness direction of the metal plate 20. By spaced apart multiple fixing protrusions 72, the contact area between the support member 70 and the filling layer 40 can be further increased, thereby further improving the fixing reliability between the support member 70 and the filling layer 40.

[0057] In some embodiments, such as Figure 4 As shown, the fixing protrusion 72 is symmetrical with respect to the central axis of the extending direction of the support body 71. By making the fixing protrusion 72 symmetrical with respect to this central axis, the force exerted by the filling layer 40 on the support member 70 can also be symmetrical with respect to the central axis of the support body 71. For example, when the support member 70 is subjected to the force of the filling layer 40 and the force is not parallel to the extending direction of the support body 71, the separation perpendicular to the extending direction caused by the force can cancel each other out, thereby reducing the risk of lateral displacement of the support member 70 under the force of the filling layer 40, and further improving the fixing reliability of the support member 70 and the filling layer 40. Optionally, the fixing protrusion 72 is located on both sides of the central axis of the support body 71 and is symmetrically arranged with respect to the central axis, thereby saving the material required to manufacture the support member 70; optionally, as Figure 5 As shown, the fixed protrusion 72 extends around the central axis of the support body 71 in the direction of extension, forming a structure with the ends connected. That is, the fixed protrusion 72 extends to form a ring structure with the ends connected. In the direction of the central axis of the support body 71, the external force of the filling layer 40 borne by the fixed protrusion 72 is symmetrically distributed with respect to the central axis. Therefore, it is not necessary to distinguish the installation angle of the support 70 during the installation of the support member 70, which improves the ease of installation of the support member 70.

[0058] In some embodiments, such as Figure 6As shown, the thickness of the fixed protrusion 72 decreases in the extension direction of the fixed protrusion 72. This thickness is the dimension of the fixed protrusion 72 perpendicular to the extension direction. That is, the fixed protrusion 72 forms a structure that is thinner the further away from the outer surface of the supporting body 71. This allows a guide surface to be formed on the outer surface of the fixed protrusion 72. During the process of fixing the fixed protrusion 72 inside the filling layer 40 by casting, the material of the filling layer 40 can be more evenly distributed through this guide surface. Optionally, the guide surface can be a curved surface or an inclined plane.

[0059] In some embodiments, such as Figure 7 As shown, the fixed protrusion 72 includes an abutment surface 721. In the extending direction of the support body 71, the abutment surface 721 is located on the side of the fixed protrusion 72 away from the metal plate 20, and the abutment surface 721 is perpendicular to the outer surface of the support body 71, thereby forming a plane that is approximately parallel to the fixed surface of the metal plate 20. When the metal plate 20 presses against the support member 70, the force can be fully borne by the abutment surface 721 and no component of the force will be generated in the lateral direction. This enables the support member 70 to support the metal plate 20 more reliably and improves the overall structural rigidity of the metal composite wall panel.

[0060] In some embodiments, such as Figure 7 As shown, the fixed protrusion 72 also includes a guide slope 722. The guide slope 722 is located on the side of the fixed protrusion 72 closest to the metal plate 20. The guide slope 722 extends in a direction away from the metal plate 20. That is, by making the guide slope 722 extend in a direction away from the metal plate 20, the thickness of the fixed protrusion 72 can be reduced while forming the guide slope 722. The guide slope 722 can squeeze the filling layer 40, thereby making the distribution of the filling layer 40 more uniform. Moreover, the manufacturing difficulty of the fixed protrusion 720 can be reduced by forming the guide slope 722 by using an inclined plane.

[0061] In some embodiments, such as Figure 8 As shown, the support member 70 also has an adhesive cavity 73 on the side near the metal plate 20. The adhesive cavity 73 is filled with adhesive material. The support member 70 is connected to the fixed surface of the metal plate 20 through the adhesive material. By providing the adhesive cavity 73, more adhesive material can be accommodated and the adhesive material is confined inside the adhesive cavity 73, thereby enabling the support member 70 to be more reliably connected to the fixed surface of the metal plate 20. The adhesive material can be any material that can achieve bonding. For example, the adhesive material can be structural adhesive or epoxy resin.

[0062] It should be noted that the bonding cavity 73 can be formed in any way. For example, the bonding cavity 73 is formed by recessing the end of the support member 70 near the metal plate 20, which can reduce the processing difficulty of the bonding cavity 73 while forming it; for example, such as Figure 8 As shown, the support member 70 also includes a partition protrusion 74, which is located at the end of the support body 71 near the metal plate 20, and the partition protrusion 74 surrounds and forms an adhesive cavity 73. This allows the adhesive cavity 73 to be formed without reducing material, thereby improving the fixing reliability between the support member 70 and the metal plate 20, and also improving the structural strength of the support member 70.

[0063] In some embodiments, such as Figure 8 As shown, at least two parts of the separating protrusion 74 form a support portion 741. In the direction in which the separating protrusion 74 extends, the support portion 741 has the same size as and is larger than the size of the other parts. The support portion 741 is used to abut against the fixing surface of the metal plate 20. It can be understood that by setting at least two support portions that protrude from the other parts to form a positioning plane, when the support portion 741 abuts against the fixing surface of the metal plate 20, the installation positioning of the support member 70 and the metal plate 20 can be realized, thereby making the installation of the support member 70 and the metal plate 20 more convenient and reliable.

[0064] In some embodiments, such as Figure 9 As shown, the separating protrusions 74 surround the central axis of the support body 71 in the extension direction to form a structure with the ends connected. That is, the separating protrusions 74 surround to form a ring structure, so that the adhesive cavity 73 has the same size in all directions around the central axis. When installing the support member 70, there is no need to distinguish the angle of the support member 70, which further reduces the installation difficulty of the support member 70.

[0065] In some embodiments, such as Figure 10 As shown, the support member 70 also includes an adhesive portion 75, which is located at the end of the support body 71 near the metal plate 20, and an adhesive cavity 73 is located at the end of the adhesive portion 75 near the metal plate 20. In the direction perpendicular to the extension of the support body 71, the size of the adhesive cavity 73 is larger than the size of the support body 71. That is, by providing the adhesive portion 75 and making the adhesive portion 75 have a larger size in the direction perpendicular to the extension of the support body 71, a larger processing space is formed for the adhesive cavity 73, thereby enabling the adhesive cavity 73 to have a larger size, which further improves the fixing reliability between the support member 70 and the metal plate 20.

[0066] In some embodiments, such as Figure 11As shown, the filling layer 40 includes an insulation layer 42 and a protective layer 43, which are arranged sequentially along a first direction. The insulation layer 42 is located between the metal plate 20 and the protective layer 43. The insulation layer 42 improves the insulation capacity of the metal exterior wall, and the protective layer 43 protects the insulation layer 42, thereby improving the structural reliability of the insulation layer 42. The support member 70 is located inside both the insulation layer 42 and the protective layer 43. Both the portion of the support member 70 inside the insulation layer 42 and the portion inside the protective layer 43 have at least one fixing protrusion 72, ensuring a reliable connection between the support member 70 and both the insulation layer 42 and the protective layer 42.

[0067] This utility model embodiment also provides a metal exterior wall structure. The structure and function of the metal exterior wall structure will be described exemplarily below with reference to various embodiments.

[0068] In some embodiments, such as Figure 1 As shown, the metal exterior wall structure includes: wall 30, connecting plate 200, and connecting structure 100, as well as the components shown in the attached drawings of the specification. Figures 2 to 11 In any of the metal composite wall panels shown, the connecting plate 200 connects the wall 30 and the connecting structure 100, and the connecting structure is fixedly connected to the metal composite wall panel, thereby fixing the metal composite wall panel to the wall 30.

[0069] In some embodiments, such as Figure 12 As shown, in the vertical direction, two connecting structures 100 are fixed to both sides of the metal plate 20, and at least one support member 70 is located between the two connecting structures 100. It can be understood that a first force is applied to the edge of the metal plate 20 at both ends through the connecting structures 100, and a second force is applied to the metal plate 20 in the middle through the support member 70. The first and second forces are opposite in the vertical direction to keep the metal plate 20 in a state of force balance. At the same time, the torques generated by the two forces are opposite, thereby limiting the warping of the middle region of the metal plate 20, and thus keeping the metal plate 20 in close contact with the filling layer 40. This not only improves the aesthetics of the metal exterior wall structure, but also provides more reliable protection for the metal filling layer 40 through the metal plate 20, reduces the risk of partial detachment of the filling layer 40, and improves the structural reliability of the metal exterior wall structure.

[0070] In some embodiments, such as Figure 13 As shown, the connecting structure 100 includes a bonding wall 110 and an extending wall 120. The outer surface of one side of the bonding wall 110 forms a bonding surface 111, which is used to bond with the metal plate 20 to achieve a fixed connection. It should be noted that the bonding surface 111 can be directly bonded to the metal plate 20 using structural adhesive. Figure 1The metal plate 20 is fixedly connected, and the mating surface 111 can also form a groove, which accommodates the structural adhesive and is mated to the metal plate 20, thereby fixing it to the metal plate 20.

[0071] The extension wall 120 further surrounds and forms a slot 121, the opening of which faces the mating surface 111. The metal plate 20 includes a plate body 21 and a fixing edge 22. The plate body 21 has a fixing surface for mating with the mating surface 111. The fixing plate 22 protrudes from this fixing surface and is inserted into the slot 121. The opening of the slot 121 is not parallel to the fixing surface of the plate body 21, allowing the fixing edge 22 to be inserted into the slot 121. By providing the slot 121, the metal plate 20 can... The metal plate 20 is more reliably fixed to the connecting structure 100. Furthermore, by providing the slot 121, a torque can be applied to the metal plate 20. This torque pulls the edges of the metal plate 20 towards the wall 30, but also causes a slight warping of the central region of the metal plate 20 away from the wall 30. A support member 70 is provided in the central region of the metal plate 20 to resist this warping tendency through the applied tension, thereby enabling the metal plate 20 to be more reliably fixed to the connecting structure 100 and the filling layer 40. It should be noted that the connecting structure 100 can be any structure with the slot 121; for example, the slot 121 can be a structure formed by machining.

[0072] In some embodiments, such as Figure 13 As shown, the connecting structure 100 includes a bonding wall 110 and an extending wall 120. The outer surface of one side of the bonding wall 110 forms a bonding surface 111, which is used to bond with the metal plate 20 to achieve a fixed connection. It should be noted that the bonding surface 111 can be directly bonded to the metal plate 20 using structural adhesive. Figure 1 The metal plate 20 is fixedly connected, and the mating surface 111 can also form a groove, which accommodates the structural adhesive and is mated to the metal plate 20, thereby fixing it to the metal plate 20.

[0073] The extension wall 120 extends from the surface of the mating wall 110 opposite to the mating surface 111, and the extension wall 120 extends along a first direction (the first direction is as follows). Figure 13As indicated by the middle arrow, the extension wall 120 extends in a direction that is not parallel to the mating surface 111, thereby allowing the extension wall 120 to extend away from the mating wall 110. The extension wall 120 surrounds and forms a slot 121, the opening direction of which is not parallel to the mating surface 111. The slot 121 is used to accommodate the fixing edge 22 of the metal plate 20. It can be understood that the metal plate 20 includes a plate body 21 and a fixing edge 22, which extends along the thickness direction of the plate body 21. The fixing edge 22 is inserted into the slot. Within slot 121, the metal plate 20 can be bonded to the bonding wall 110 via the bonding surface 111, and simultaneously inserted into the extension wall 120 via the slot 121. That is, not only does the adhesive force between the bonding surface 111 and the metal plate 20 bear the tangential force between the metal plate 20 and the connecting structure 100, but the force between the fixed edge 22 and the slot 121 also bears the bending moment exerted by the metal plate 20 on the connecting structure 100. This makes the fixation of the metal plate 20 to the connecting structure 100 more reliable and reduces the risk of the metal plate 20 falling off. Furthermore, when the metal plate 20 is thin, it may bend under external force or assembly force. By inserting the edge of the metal plate 20 into the slot 121, the force exerted on the metal plate 20 by the slot 121 can also limit the bending deformation of the metal plate.

[0074] In some embodiments, such as Figure 14 As shown, multiple connecting structures 100 are spliced ​​together to form a connecting frame 50. The connecting frame 50 is a structure that is connected end to end. The connecting frame 50 is fixedly connected to multiple connecting plates 200. It can be understood that the metal plate 20 forms an integral structure by combining with the connecting frame 50, so that the metal plate 20 can be fixedly connected to multiple connecting plates 200 at the same time through the connecting frame 50. This allows the load borne by the metal plate 20 to be transferred to multiple connecting plates 200 at the same time, thereby further improving the fixing reliability of the metal plate 20 and the wall panel 30. Furthermore, the space formed by the connecting frame 50 can surround the filling layer 40, and at least a portion of the filling layer 40 can be connected to the inner wall of the space. This can be understood as follows: in the direction perpendicular to the thickness of the filling layer 40, the connecting frame 50 surrounds and tightens the filling layer 40; in the direction parallel to the thickness of the filling layer 40, the metal plate 20 adheres to and protects the filling layer 40; and the support member 70 makes the adhesion between the metal plate 20 and the filling layer 40 tighter, thereby better protecting the filling layer 40. That is, by setting the metal plate 20 and the connecting frame 50, the filling layer 40 is protected and supported from multiple directions, thereby reducing the risk of loose parts of the filling layer 40 coming loose, and making the filling layer 40 more reliably maintain its function. For example, when the filling layer 40 includes thermal insulation material, the filling layer 40 can more reliably achieve its thermal insulation function.
