Description

Technical Field

[0001] This utility model relates to a wall mounting system, and more particularly to a wall metal panel mounting system. Background Technology

[0002] In modern architectural decoration, metal panels, as a high-strength, corrosion-resistant, and aesthetically pleasing wall covering material, are widely used in the installation of building facades and interior walls. Types of metal panels include aluminum, stainless steel, copper, and galvanized steel. With the popularization of prefabricated construction concepts, achieving rapid installation and precise joint alignment of metal panels has become an important direction for improving construction efficiency and aesthetic quality.

[0003] Currently, common installation methods for metal panels include using a keel structure made of angle steel, channel steel, and other profiles, with the metal panels attached to the keel using bolts, nuts, and other fasteners. To achieve splicing between metal panels, connectors (such as angle brackets) are usually installed at the joints, and gaps are reserved as needed for subsequent sealant application. In actual construction, welding, smoothing, and caulking are also required at the joints to ensure their sealing and integrity. The entire installation process primarily relies on mechanical connections and caulking, and is suitable for the construction of various building curtain walls or interior structures.

[0004] However, existing installation methods generally suffer from problems such as loose assembly structures, complex construction steps, and unsatisfactory joint finishes. On the one hand, because metal panel splicing requires pre-reserved process seams and relies on sealant for finishing, the sealant seams are relatively wide, affecting the overall appearance and posing a risk of cracking and aging. On the other hand, traditional corner bracket structures usually require on-site welding or drilling, resulting in low construction efficiency, high reliance on manual operation, and difficulty in achieving standardized and modular assembly. Therefore, there is an urgent need to propose a new metal panel installation system for walls. Utility Model Content

[0005] The purpose of this utility model is to provide a wall metal panel installation system that achieves fast, accurate, and secure snap-fit ​​assembly by grouping several clips on the keel mounting surface to form a continuous assembly area, and cooperating with the snap-fit ​​structure on one side of the metal panel.

[0006] The technical solution adopted by this utility model to solve the above problems is: a wall metal panel installation system for assembling a plurality of metal panels on the wall surface, comprising:

[0007] A keel assembly, which is fixed to the wall surface, wherein the side of the keel assembly facing away from the wall surface is defined as the mounting surface;

[0008] Several fasteners are disposed on the mounting surface. Each fastener has a slot extending through a first direction on the side away from the mounting surface. The first direction is parallel to the vertical direction. All fasteners are divided into several groups. The fasteners in each group are arranged sequentially along a second direction, which is parallel to the horizontal plane. Furthermore, all the fasteners in each group are arranged sequentially along the first direction, so that the slots on all the fasteners in a group are combined to form an assembly area.

[0009] The metal plate has at least one engaging structure on one side that is adapted to the assembly area. The engaging structure is configured to engage within the assembly area when the metal plate is installed on the mounting surface, and the extending direction of the engaging structure is parallel to the first direction.

[0010] Preferably, the locking element is configured such that when the locking structure is engaged in the assembly area, the opposite sides of the inner wall of the slot simultaneously apply a resisting force to the opposite sides of the locking structure to increase the friction between the locking structure and the slot.

[0011] Preferably, the inner wall of the slot is provided with toothed grooves on both sides, and the toothed grooves are inclined to the mounting surface.

[0012] Preferably, the keel assembly includes:

[0013] Angle bracket, which is fixedly connected to the wall surface;

[0014] The vertical keel is fixedly connected to the corner bracket, and the side of the vertical keel facing away from the wall is the mounting surface;

[0015] A horizontal keel, which is fixedly connected to the vertical keel.

[0016] Preferably, the keel assembly further includes a leveling component, which is disposed on the side of the horizontal keel away from the wall. The leveling component is configured such that when the metal plate is installed at the mounting surface, the side of the leveling component away from the wall abuts against the side of the metal plate facing the wall.

[0017] Preferably, the leveling component has an adhesive layer on the side facing the metal plate.

[0018] Preferably, the installation system further includes a filler strip disposed between two adjacent metal plates to fill the seam between the two metal plates.

[0019] Preferably, the installation system further includes an arc-shaped corner profile, which is disposed between two adjacent metal plates that are perpendicular to each other. The two end faces of the arc-shaped corner profile along the arc extension direction are detachably connected to the adjacent sides of the two adjacent metal plates, and the arc-shaped surface of the arc-shaped corner profile smoothly transitions to the side of the metal plate that is away from the wall.

[0020] Preferably, the arc-shaped corner profile is fixedly connected to the keel assembly.

[0021] The beneficial effects of the embodiments of this utility model are as follows:

[0022] Because this wall panel installation system adopts a structural design that arranges several clips in horizontal groups and forms a combined assembly area in the vertical direction within each group, and has a snap-fit ​​structure on one side of the metal panel that matches the assembly area, the metal panel can be quickly positioned and stably installed at the installation surface through vertical insertion. Therefore, it effectively solves the problems of rough seams, cumbersome construction procedures, the need for glue treatment at the joints, and the inability to achieve standardized and rapid assembly in the existing technology. As a result, it achieves the technical effect of rapid assembly of metal panels, tight splicing, high aesthetics, and no need for glue finishing, improving construction efficiency and wall assembly accuracy, and is suitable for modular and industrialized batch construction needs.

Those skilled in the art will understand the specific meaning of the above terms in this application based on the specific circumstances.

[0029] See Figure 1 A preferred embodiment of this application provides a wall metal panel 30 installation system for assembling a plurality of the metal panels 30 on the wall. The installation system includes a keel assembly 10, several clips 20, and a metal plate 30. The keel assembly 10 is fixed to the wall surface, and the side of the keel assembly 10 facing away from the wall surface is defined as the mounting surface 121. Several clips 20 are disposed on the mounting surface 121, and each clip 20 has a slot 210 extending along a first direction parallel to the vertical direction on the side facing away from the mounting surface 121. All clips 20 are divided into several groups, and the clips 20 in each group are arranged sequentially along a second direction parallel to the horizontal plane. Furthermore, all the clips 20 in each group are arranged sequentially along the first direction, so that the slots 210 on all the clips 20 in a group combine to form an assembly area. One side of the metal plate 30 is provided with at least one engaging structure 310 adapted to the assembly area. The engaging structure 310 is configured to engage within the assembly area when the metal plate 30 is installed on the mounting surface 121, and the extension direction of the engaging structure 310 is parallel to the first direction.

[0030] The wall metal panel 30 installation system provided in this embodiment mainly consists of a keel assembly 10, several clips 20 and metal panels 30, and is used to realize the rapid and neat installation of multiple metal panels 30 on the wall.

[0031] Specifically:

[0032] The keel assembly 10 includes at least one base structure set along the wall surface and fixedly connected to the building wall. The material can be aluminum alloy, stainless steel, or galvanized steel, and it has good load-bearing capacity and corrosion resistance. The side of the keel assembly 10 facing away from the wall surface is defined as the mounting surface 121. The mounting surface 121 can be a flat surface or a structure with reinforcing ribs to enhance the overall stability of the system.

[0033] The clips 20 are evenly distributed on the mounting surface 121. Each clip 20 can be a one-piece molded structure, made of engineering plastic or metal. The side of the clip 20 facing away from the mounting surface 121 has a through groove 210 extending along a first direction, which is vertical. The groove 210 can be T-shaped, U-shaped, or rectangular through groove, and its size matches the engaging structure 310 of the metal plate 30.

[0034] Furthermore, all the card pieces 20 are divided into several groups, and the card pieces 20 in each group are arranged sequentially along the horizontal direction (second direction). All the card pieces 20 in each group are arranged at equal intervals along the first direction (vertical direction), so that the card slots 210 on each group of card pieces 20 form a continuous channel in the vertical direction, i.e., the assembly area.

[0035] The metal plate 30 has at least one engaging structure 310 on its back side. This structure is a strip-shaped flange or insert portion that matches the assembly area and has the same size and shape as the slot 210. The extending direction of the engaging structure 310 is parallel to the first direction, ensuring a stable fit when it is inserted into the slot 210 in the vertical direction.

[0036] The installation process of this system is as follows: The keel assembly 10 is fixed to the target wall surface using expansion bolts or other fasteners, ensuring that its mounting surface 121 faces outwards and remains flat. According to the design drawings, the clips 20 are installed in groups on the mounting surface 121 of the keel assembly 10. Each group of clips 20 is positioned horizontally, with the clips 20 within each group arranged vertically at equal intervals to form a continuous set of slots 210. The engaging structure 310 on one side of the metal plate 30 is aligned with the target assembly area and inserted vertically from top to bottom or bottom to top. After the engaging structure 310 is inserted into the slot 210, it achieves a stable connection through its own structural holding, preventing shaking or loosening. The metal plates 30 are then sequentially engaged and installed, ensuring tight alignment of the joints without the need for sealant or welding.

[0037] Among them, the grouping and alignment accuracy of the card slots 210 of the card pieces 20 is the key to ensuring the continuity of the assembly area and the consistency of the joints. The insertion angle and insertion force control of the metal plate 30 are directly related to the card fastening firmness and construction safety. Furthermore, the plate posture adjustment and auxiliary alignment tools during on-site construction can improve the installation accuracy by setting up guide structures or installing auxiliary clamps. Moreover, if the modular keel assembly 10 is used, it has positioning holes, markings or guide rails, which can accelerate the construction alignment process.

[0038] The wall metal panel 30 installation system provided in this embodiment adopts a modular fastener 20 grouping structure, forming continuous assembly areas within each group of fasteners 20. This allows for rapid assembly and precise positioning of the metal panels 30, effectively avoiding complex processes such as welding, bolting, and sealant application in traditional installation methods. This significantly simplifies the construction process and reduces reliance on manual labor. After installation, the system produces neat seams and a uniform appearance, achieving a tight joint without the need for sealant treatment, resulting in a significantly improved overall aesthetics. Furthermore, this installation method can be standardized and replicated, making it particularly suitable for industrialized and prefabricated building construction scenarios. It also offers excellent maintenance convenience, as the metal panels 30 can be plugged in and replaced, adapting to localized maintenance needs during long-term use.

[0039] In some embodiments, the locking member 20 is configured such that when the engaging structure 310 is engaged in the assembly area, the opposite sides of the inner wall of the slot 210 simultaneously apply a holding force to the opposite sides of the engaging structure 310, thereby increasing the friction between the engaging structure 310 and the slot 210. Further, each opposite side of the inner wall of the slot 210 is provided with a toothed groove 211, which is inclined to the mounting surface 121.

[0040] The clip 20 is a functional unit located on the mounting surface 121, and its internal slot 210 structure extends vertically through it. To enhance the connection stability after the metal plate 30 is inserted into the locking structure 310, the inner walls on opposite sides of the slot 210 are designed to have elasticity or deformation capabilities. This allows the inner walls of the clip 20 to actively tighten inward after the locking structure 310 of the metal plate 30 is inserted into the assembly area, generating a continuous supporting force on both sides of the locking structure 310, thereby creating a frictional self-locking effect.

[0041] Furthermore, to achieve reliable mechanical engagement, each inner wall is provided with a toothed groove 211 arranged in a direction inclined to the mounting surface 121. The toothed groove 211 can be sawtooth-shaped, corrugated, or wedge-shaped, and the material can be a metal or engineering plastic with a certain degree of elasticity. The inclination angle of the toothed groove 211 matches the insertion direction of the engaging structure 310, thereby gradually engaging during the insertion process to form a self-locking fit.

[0042] During actual installation, the installer aligns the engaging structure 310 of the metal plate 30 with the assembly area where the clip 20 is located and inserts it vertically. During insertion, the toothed grooves 211 on both sides of the inner wall of the groove 210 gradually contact the outer surface of the engaging structure 310, forming a sliding fit in the inclined direction. Due to the reasonable angle design of the toothed grooves 211, a continuous inward clamping force is applied to the engaging structure 310 during insertion. This clamping force not only improves the initial stability of the engagement but also enhances its resistance to sagging and vibration. After insertion, the clip 20 secures the metal plate 30 through the friction and meshing force between its toothed grooves 211 and the engaging structure 310, preventing loosening or displacement.

[0043] The key to this embodiment lies in the angle setting and spacing design of the tooth grooves 211, which must simultaneously consider the insertion force and the locking and retaining force. The material hardness and shape of the tooth grooves 211 must match the locking structure 310 of the metal plate 30 to avoid failure to insert or excessive looseness after engagement. In addition, to ensure smooth assembly, the initial inner cavity size of the clamping part 20 needs to be slightly larger than that of the locking structure 310, and the engagement and locking are gradually achieved during insertion with the help of the inclined guiding effect of the inner wall tooth grooves 211. If an elastic tooth groove material is used, it is also possible to adapt to the assembly requirements under different dimensional tolerances.

[0044] This structure is suitable for metal panel wall systems that require long-term load-bearing, frequent vibration, or high wind pressure environments, such as high-rise building facades, subway station concourse walls, and highway sound barriers. It is particularly suitable for scenarios requiring high installation strength and reliability without the need for additional fasteners. The device can adapt to complex environmental conditions such as indoor and outdoor temperature and humidity changes, UV aging, and thermal shock.

[0045] In this embodiment, because an inclined toothed groove 211 structure is set on the inner wall of the slot 210 of the clip 20, and the clamping force is applied to the metal plate 30 engagement structure 310 by both sides of the slot 210, the problems of loose connection, weak shear resistance and susceptibility to vibration in the traditional metal plate 30 snap-fit ​​are effectively solved. Thus, a stable installation effect can be achieved without screws or glue, which significantly improves the installation firmness and structural reliability, and adapts to the wall decoration needs of various high-load and complex environments.

[0046] In some embodiments, the keel assembly 10 includes a corner bracket 110, a vertical keel 120, a horizontal keel 130, and a leveling component 140. The corner bracket 110 is fixedly connected to the wall surface, the vertical keel 120 is fixedly connected to the corner bracket 110, the side of the vertical keel 120 facing away from the wall surface is the mounting surface 121, the horizontal keel 130 is fixedly connected to the vertical keel 120, and the leveling component 140 is disposed on the side of the horizontal keel 130 facing away from the wall surface. The leveling component 140 is configured such that when the metal plate 30 is installed at the mounting surface 121, the side of the leveling component 140 facing away from the wall surface abuts against the side of the metal plate 30 facing the wall surface, and the side of the leveling component 140 facing the metal plate 30 is provided with an adhesive layer 141.

[0047] In this embodiment, the keel assembly 10 in the wall metal panel 30 installation system consists of corner brackets 110, vertical keels 120, horizontal keels 130 and leveling components 140, and the components together form a stable load-bearing and installation structure system.

[0048] Angle bracket 110 is used to firmly fix the entire keel assembly 10 to the building wall surface. It is preferably an L-shaped steel part or an aluminum alloy part, and can be installed on the wall base surface such as concrete or brick wall by means of expansion bolts, chemical anchors, etc.

[0049] The vertical keel 120 extends vertically, and one end of it is fixedly connected to the corner bracket 110 by mechanical connection or welding to form the first-level structural support. The side of it away from the wall serves as the mounting reference surface of the metal plate 30, namely the mounting surface 121.

[0050] The horizontal keel 130 is set in the horizontal direction and connected perpendicularly to the vertical keel 120. It is preferred to use plug-in, screw-in or spot welding to form an interlaced structure to enhance the overall bending resistance and stability.

[0051] The leveling component 140 is disposed on the surface of the transverse keel 130 near the metal plate 30. Its material can be engineering plastic, rubber pad, foam or elastic composite material. It is used to provide elastic support and surface transition during the installation of the metal plate 30. An adhesive layer 141 is provided on the side facing the metal plate 30. Double-sided tape, hot melt adhesive or pressure-sensitive adhesive can be used to improve the initial bonding strength with the metal plate 30.

[0052] In the actual installation process, the corner brackets 110 are first pre-embedded or installed on the wall base by mechanical fixing. Then, the vertical keel 120 is positioned and installed using the corner brackets 110, ensuring that its outward-facing mounting surface 121 is in the same vertical plane. Next, the horizontal keel 130 is laid out and fixed along the vertical keel 120 to achieve a grid-like construction of the mounting surface 121. Then, the leveling component 140 is attached to the side of the horizontal keel 130 away from the wall, and its height or thickness is adjusted so that its surface is flush with or slightly higher than the mounting surface 121. The metal plate 30 is then pushed and installed in the snap-fit ​​structure, and the back of the metal plate 30 abuts against the surface of the leveling component 140 to form a surface support. The adhesive layer 141 generates an initial adsorption force to assist in positioning. Finally, after the snap-fit ​​structure is locked, the leveling component 140 will maintain the anti-floating and buffering effect on the metal plate 30.

[0053] In this embodiment, the vertical accuracy between the corner bracket 110 and the vertical keel 120 directly determines the verticality of the installation reference plane. The installation position and thickness uniformity of the leveling component 140 are important parameters to ensure the flatness of the metal plate 30 surface. The adhesion and holding power of the adhesive layer 141 play a key role in the initial positioning stage. Especially in the installation of large-size metal plates 30, it can effectively prevent the plate from sagging or sliding. Furthermore, if the leveling component 140 is an elastic structure, it can also buffer thermal expansion and contraction and absorb vibration, thus extending the system life.

[0054] In this embodiment, by incorporating a leveling component 140 within the keel assembly 10, with its side facing away from the wall abutting against the back of the metal plate 30, and equipped with an adhesive layer 141, the problem of unevenness, surface fluctuation, and misaligned seams in the metal plate 30 caused by uneven walls after installation can be effectively solved. This achieves multi-point support, initial positioning assistance, and stress dispersion for the mounting surface 121 of the metal plate 30. Furthermore, this structure eliminates the need for additional leveling or precision wall grinding, improving construction efficiency and reducing labor costs. It is particularly suitable for large-size panels or industrialized assembly construction scenarios, exhibiting excellent adaptability and engineering practicality.

[0055] In some embodiments, the installation system further includes a filler strip disposed between two adjacent metal plates 30 to fill the seam between the two metal plates 30.

[0056] In this embodiment, the wall panel metal plate 30 installation system further includes a filler strip assembly. This filler strip is a strip-shaped component disposed between two adjacent metal plates 30 to fill the gap formed between them. The shape of the filler strip is customized according to the edge contour of the metal plate 30 and the installation gap, typically in the form of an "I," "T," "V," or wedge cross-section. Materials can include elastic rubber, PVC, EPDM, silicone, metal spring-coated structures, etc., possessing good resilience, weather resistance, and dimensional stability.

[0057] The outer edges of the filler strip fit tightly against the edges of the adjacent metal plates 30. After being filled into the joint, it provides a limiting effect in the horizontal direction and a certain amount of resistance in the vertical direction, serving multiple functions such as sealing, dustproofing, waterproofing, light transmission prevention, shock absorption, and aesthetic enhancement of the joint. At the same time, the length direction of the filler strip is consistent with the joint direction of the metal plates 30, extending through the length or height of the plates.

[0058] After the metal plates 30 are installed, the construction personnel select the appropriate size of filler strip according to the width and depth of the joint formed between the metal plates 30, and press it into the gap along the joint direction. The filler strip can be installed manually, by tool-assisted pressing, or by sliding. Because the filler strip itself is elastic, it can generate a certain prestress in the joint during installation, thereby stably embedding and forming a reliable fit. In some embodiments, the filler strip is also equipped with claws, dovetail grooves, or a surface roughening layer to further improve its resistance to displacement.

[0059] Among them, the size matching of the filler strip is a key parameter to ensure sealing and appearance. It is generally required that the height of the filler strip is slightly greater than the joint depth, and the width and gap tolerance should be matched. The uniformity control during the pressing process affects the straightness of the line and the surface transition effect after the filler strip is embedded. If there are slight fluctuations in the joint width, the filler strip needs to have good elastic recovery ability to prevent local detachment or tightness marks. In high-requirement applications, the filler strip can also adopt a double-layer structure, with a rigid skeleton inner layer and a flexible outer layer to improve long-term durability and visual consistency.

[0060] In this embodiment, the addition of a filler strip structure between the joints of the metal plates 30, with its structure, material, and dimensions precisely matching the joints, effectively solves the problem of gaps between the metal plates 30 caused by installation tolerances, thermal expansion and contraction, or on-site deviations. This achieves multiple technical effects, including aesthetically pleasing joints, dustproofing, waterproofing, and shock absorption. Furthermore, this structure is easy to install, highly maintainable, and provides good decorative continuity, making it particularly suitable for applications requiring meticulous finishing in standardized construction and industrialized assembly scenarios.

[0061] Please see Figure 2In one embodiment, the installation system further includes an arc-shaped corner profile 40, which is disposed between two adjacent metal plates 30 that are perpendicular to each other. The two end faces of the arc-shaped corner profile 40 along the arc extension direction are detachably connected to the adjacent sides of the two adjacent metal plates 30, and the arc-shaped surface of the arc-shaped corner profile 40 smoothly transitions to the side of the metal plate 30 that is away from the wall. The arc-shaped corner profile 40 is fixedly connected to the keel assembly 10.

[0062] In this embodiment, the wall metal panel 30 installation system further includes an arc-shaped corner profile 40, which is used to install between two adjacent metal panels 30 (metal panels 30 at the front corner) that are arranged perpendicularly, serving as a transition, connection, and decoration function. The arc-shaped corner profile 40 has an arc-shaped plate structure, with its two end faces along the arc extension direction facing the adjacent edges of the two metal panels 30 respectively, and is edge-connected to the two metal panels 30 through a detachable connection method (such as a buckle, screw, or slide rail slot structure).

[0063] The outer curved surface of the arc-shaped corner profile 40 faces the visible side of the installation system (i.e., the side of the metal plate 30 facing away from the wall). Its radius of curvature is designed according to the needs of the corner transition to achieve a smooth curved surface transition with the metal plate 30, eliminating sharp-angle visual sections and improving the overall flatness and continuity of the decoration. The back of the arc-shaped corner profile 40 is fixedly connected to the corresponding position of the keel assembly 10 by screws, clips, connecting brackets, etc., to ensure its structural stability. In terms of materials, the arc-shaped corner profile 40 is preferably made of aluminum alloy, stainless steel, or high-strength composite materials. Homogeneous or compatible materials can be selected according to the material of the metal plate 30. Surface treatment methods include anodizing, electrophoresis, powder coating, or wire drawing.

[0064] During installation, space is first reserved in the joint area of ​​the two right-angled metal plates 30 for the installation of the curved corner profile 40. After the main metal plate 30 is installed, the workers position the curved corner profile 40 between the two plates, ensuring its end face aligns with the vertical edges of the two plates, and fixes it using corresponding connection structures (such as screw locking or clamping with slot 210). Finally, it is reliably connected to the keel assembly 10 via the bottom structure. After installation, the curved surface visually conceals the curve at the joint of the two metal plates 30 and completes the structural finish. Furthermore, there is no obvious step difference between the curved surface and the metal plate 30 surface, presenting a continuous corner transition effect, which improves the overall appearance and enhances the structure's resistance to deformation.

[0065] Among them, the curvature and thickness matching design of the arc-shaped corner profile 40 is the key to ensuring smooth splicing and visual harmony. The ease of disassembly of the connection structure determines the operability of later maintenance or replacement. It is recommended to adopt a non-destructive connection method. The positioning interface structure with the keel component 10 should be equipped with a limit guide or quick fixing mechanism to prevent loosening due to vibration during use. In addition, stress concentration at the corner should be prevented during installation. Reinforcing ribs or buffer layers can be designed on the arc-shaped back.

[0066] In this embodiment, an arc-shaped corner profile 40 is used between two vertical metal plates 30. Both ends of the profile are detachably connected to adjacent plates, and the outer arc surface smoothly transitions to the metal plate 30. Simultaneously, the bottom structure can be fixedly connected to the keel. Therefore, the problems of unsightly seams, rigid structural connections, and difficult maintenance at traditional corner locations are effectively solved. This achieves the technical effects of structural reinforcement, visual optimization, and modular splicing of the metal plate 30 system in the corner area. This structure is easy to construct, has a strong consistency in appearance, and is highly maintenance-friendly, making it suitable for standardized industrialized mass assembly needs.

[0067] Furthermore, the snap-fit ​​connection method formed by the snap-fit ​​structure 310 and modular clips 20 used in this embodiment also has significant technical advantages in practical applications: In terms of installation efficiency, the snap-fit ​​installation structure is simple and quick to operate, eliminating the need for tedious processes such as drilling and tightening required by traditional screw fixing, significantly reducing tool dependence and labor intensity. In large-area metal panel 30 installation tasks, especially in large building facades or curtain wall projects, it can effectively improve work efficiency and shorten the construction cycle; In terms of installation flexibility, this snap-fit ​​structure can adapt to the changes in the panel caused by factors such as temperature changes and structural settlement. Micro-displacement or deformation prevents warping or damage caused by stress accumulation in the panels, enhancing the stability of the connection and the safety of long-term use. In terms of aesthetics, the snap-fit ​​connection has no exposed fasteners, and the joints are neat and tight, presenting a smooth and unified visual appearance, which meets the high standards of modern architecture for decorative effects. In terms of the convenience of later maintenance and replacement, if it is necessary to replace damaged panels or inspect and maintain the internal structure of the wall, the metal panel 30 can be removed simply by unlocking the snap-fit. After the operation is completed, it can also be quickly reinstalled, which facilitates maintenance, inspection and partial updates, greatly improving the system's maintainability and life cycle controllability.

[0068] The above description in this specification is merely illustrative of the present invention.
