Technical Field
[0001] This application relates to the field of building construction technology, specifically to an environmentally friendly hard-cover wall structure. Background Technology
[0002] Hard wall paneling is a common decorative method in architectural decoration, mainly used to enhance the aesthetics and functionality of walls. Currently, common wall decoration materials on the market include paint, wallpaper, soft wall panels, and hard wall panels. Hard wall panels are widely used in high-end residences, hotels, and office buildings due to their durability, ease of cleaning, and good decorative effect. With increasing demands for living environments, the market demand for hard wall paneling is growing year by year. However, existing hard wall paneling methods still have certain problems in terms of construction efficiency, environmental performance, and installation stability, which need to be improved.
[0003] Currently, the main methods for implementing hard wall coverings include the following: First, using a wooden frame combined with decorative panels, fixing the panels to the wooden frame with adhesive; second, using a metal frame combined with decorative panels, fixing the panels to the metal frame with screws or clips; and third, using prefabricated hard wall covering modules, which are assembled to complete the wall decoration. The advantages of the wooden frame method are simple construction and low cost, but it suffers from problems such as easy deformation and poor fire resistance. The advantages of the metal frame method are good stability and high fire resistance, but it is complex to construct and more expensive. The advantages of the prefabricated hard wall covering module method are fast construction speed, but it requires a high degree of wall flatness, and gaps are prone to appear at the joints. In existing technologies, wooden frames are prone to moisture and deformation, leading to cracking or detachment of the decorative panels. Metal frames are complex to construct and heavy, increasing the load on the wall. Prefabricated hard wall covering modules have high requirements for wall flatness and poor adaptability. In addition, the environmental performance of existing hard-panel structures is generally insufficient. Adhesives and decorative panels may release harmful substances, affecting indoor air quality and making it inconvenient to replace decorative panels. Therefore, an environmentally friendly hard-panel structure for walls is provided. Utility Model Content
[0004] To address the shortcomings of existing technologies, this application provides an environmentally friendly hard-panel wall structure that reduces wall load, improves installation stability, facilitates construction on uneven walls, ensures the environmental performance of materials, and facilitates wall panel replacement.
[0005] To achieve the above objectives, this application provides the following technical solution: an environmentally friendly hard-panel wall structure, comprising a wall, a decorative panel, and corner brackets. The decorative panel is disposed on the front side of the wall, and the corner brackets are disposed on the front side of the wall. An expansion bolt passes through the interior of the front side of the corner bracket, and the corner bracket is fixedly connected to the wall via the expansion bolt. A vertical keel is disposed on the right side of the corner bracket, and a first screw passes through the right side of the corner bracket. The vertical keel is fixedly connected to the corner bracket via the first screw. A horizontal keel is disposed on the front side of the vertical keel, and a second screw passes through the interior of the horizontal keel. The horizontal keel is fixedly connected to the vertical keel via the second screw. A hanging piece is disposed on the rear side of the decorative panel, and a third screw passes through the interior of the hanging piece. The hanging piece is fixedly connected to the decorative panel via the third screw, and the hanging piece and the horizontal keel are interlocked.
[0006] The above solution, using corner brackets, vertical keels, horizontal keels, hanging plates, and decorative panels, allows workers to install decorative panels by using expansion bolts to attach the corner brackets to the wall surface, fixing the vertical keels to the side of the corner brackets with the first screw, and fixing the horizontal keels to the surface of the vertical keels with the second screw. A hanging plate is attached to the back of the decorative panel using a third bolt. The decorative panel is then installed by using the hanging plate and the horizontal keel. This detachable, prefabricated structure allows for later replacement of the decorative panel. The lightweight design of the aluminum alloy horizontal and vertical keels reduces the load on the wall, while the stainless steel hanging plates improve installation stability.
[0007] Furthermore, there are multiple sets of corner brackets, which are evenly arranged in a rectangular shape on the front side of the wall; there are multiple sets of vertical keels, which are evenly arranged on the front side of the wall; and there are multiple sets of horizontal keels, which are evenly arranged on the front side of the vertical keels.
[0008] The above scheme arranges multiple sets of corner brackets in a rectangular and uniform manner, distributing the load of the wall to multiple anchor points and avoiding local stress concentration (such as single-point overload causing wall cracking). The vertical and horizontal keels form an orthogonal grid, constituting a rigid skeleton, which significantly improves the bending and shear resistance and is suitable for large-span or heavy decorative panels (such as stone and metal panels).
[0009] Furthermore, there are multiple sets of hanging pieces, which are evenly arranged on the back side of the decorative panel. The vertical distance between each set of hanging pieces is the same as the vertical distance between each set of horizontal keels, and their positions are matched.
[0010] The above solution ensures that the spacing between multiple sets of hanging pieces is consistent with the vertical spacing of the horizontal keel and their positions correspond, thus ensuring that the decorative panel is accurately inserted into the slot by the hanging piece and eliminating the risk of misalignment during installation.
[0011] Furthermore, both the horizontal and vertical keels are made of aluminum alloy with a thickness of 1.5mm, and the hanging plates are made of stainless steel with a width of 20mm.
[0012] The above solution reduces the wall load through the lightweight design of the horizontal and vertical aluminum alloy keels.
[0013] Furthermore, the decorative panel is made of environmentally friendly high-density fiberboard with a thickness of 12mm.
[0014] Through the above methods, the formaldehyde emission of high-density fiberboard is ≤0.05mg / m³ (E0 grade), which meets the indoor environmental protection standards; the density is ≥800kg / m³, the bending strength at a thickness of 12mm is ≥30MPa, and the impact resistance is better than that of ordinary wood boards.
[0015] Furthermore, the corner bracket includes an L-shaped stainless steel frame, the surface of which has a first through hole and a second through hole, the expansion bolt passes through the first through hole, and the first screw passes through the second through hole.
[0016] The above solution allows for easy adjustment of the first screw's fixing position through the second through hole, facilitating the back-and-forth movement of the decorative panel for leveling, and is suitable for uneven wall surfaces.
[0017] Furthermore, the horizontal keel includes a keel frame body, the upper end of which is provided with a slot, the lower end of which is engaged in the slot, the lower end of which is provided with a sliding groove, and an elastic pad is provided inside the sliding groove, the elastic pad being in contact with the back side of the decorative panel.
[0018] The above solution provides protection for the back surface of the decorative panel.
[0019] Furthermore, the surfaces of the first screw, the second screw, and the third screw are all coated with anti-rust paint.
[0020] Through the above method, the anti-rust paint forms a dense protective layer on the surface of the first, second, and third screws, isolating the metal from corrosive substances such as moisture, oxygen, and salt spray, and preventing electrochemical reactions from causing rust.
[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0022] 1. This environmentally friendly hard-panel wall structure uses corner brackets, vertical keels, horizontal keels, hanging plates, and decorative panels. When workers need to install the decorative panels, they install the corner brackets on the wall surface using expansion bolts, fix the vertical keels to the side of the corner brackets with the first screw, and fix the horizontal keels to the surface of the vertical keels with the second screw. The hanging plates are connected to the back of the decorative panels with the third bolt. The decorative panels are then installed by the cooperation of the hanging plates and the horizontal keels. This is a detachable prefabricated structure, and the decorative panels can be replaced later. The lightweight design of the aluminum alloy horizontal and vertical keels reduces the load on the wall, and the stainless steel hanging plates improve installation stability.
[0023] 2. This environmentally friendly hard-pack wall structure comprises corner brackets, a first screw, a second screw, a third screw, elastic pads, and a decorative panel. The corner brackets have a second through hole on their surface, facilitating adjustment of the first screw's fixing position and allowing the decorative panel to be moved back and forth for leveling. It is suitable for uneven wall surfaces. Rust-proof paint forms a dense protective layer on the surfaces of the first, second, and third screws, isolating them from moisture, oxygen, salt spray, and other corrosive substances, preventing electrochemical reactions that could cause rust. The elastic pads protect the back surface of the decorative panel. The decorative panel is made of environmentally friendly high-density fiberboard, ensuring the material's environmental performance.

[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0033] Please see Figure 2 , Figure 3 and Figure 4 This embodiment of an environmentally friendly hard-panel wall structure includes a wall 1, a decorative panel 2, and corner brackets 3. The decorative panel 2 is located on the front side of the wall 1, and the corner brackets 3 are also located on the front side of the wall 1. Expansion bolts 4 are inserted inside the front side of the corner brackets 3, and the corner brackets 3 are fixedly connected to the wall 1 by the expansion bolts 4. A vertical keel 6 is located on the right side of the corner brackets 3, and a first screw 5 is inserted through the right side of the corner brackets 3. The vertical keel 6 is fixedly connected to the corner brackets 3 by the first screw 5. A horizontal keel 7 is located on the front side of the vertical keel 6, and a second screw 8 is inserted inside the horizontal keel 7. The horizontal keel 7 is fixedly connected to the vertical keel 6 by the second screw 8. A hanging piece 9 is located on the rear side of the decorative panel 2, and a third screw 10 is inserted inside the hanging piece 9. The hanging piece 9 is fixedly connected to the decorative panel 2 by the third screw 10. The hanging plate 9 and the horizontal keel 7 are connected by interlocking. By setting up the corner bracket 3, vertical keel 6, horizontal keel 7, hanging plate 9 and decorative panel 2, when the workers need to install the decorative panel 2, they install the corner bracket 3 on the surface of the wall 1 with the expansion bolt 4, fix the vertical keel 6 to the side of the corner bracket 3 with the first screw 5, and fix the horizontal keel 7 to the surface of the vertical keel 6 with the second screw 8. The hanging plate 9 is connected to the back of the decorative panel 2 by the third bolt. Then the decorative panel 2 is installed by the cooperation of the hanging plate 9 and the horizontal keel 7. It is a detachable prefabricated structure, and the decorative panel 2 can be replaced later. The lightweight design of the aluminum alloy horizontal keel 7 and vertical keel 6 reduces the load on the wall 1, and the stainless steel hanging plate 9 improves the installation stability.
[0034] Please see Figure 2 , Figure 3 and Figure 4 There are multiple sets of corner brackets 3, evenly arranged in a rectangular pattern on the front side of wall 1. There are also multiple sets of vertical keels 6, evenly arranged on the front side of wall 1. There are multiple sets of horizontal keels 7, evenly arranged on the front side of the vertical keels 6. There are also multiple sets of hanging pieces 9, evenly arranged on the back side of decorative panel 2. The vertical distance between each set of hanging pieces 9 is the same as the vertical distance between each set of horizontal keels 7, and their positions are matched. Both the horizontal keels 7 and vertical keels 6 are made of aluminum alloy with a thickness of 1.5mm. The hanging pieces 9 are made of stainless steel with a width of 20mm. The multiple sets of corner brackets 3 are evenly arranged in a rectangular pattern. The load of wall 1 is distributed to multiple anchor points to avoid local stress concentration (such as single-point overload causing wall cracking). The vertical keel 6 and the horizontal keel 7 form an orthogonal grid, which constitutes a rigid skeleton and significantly improves bending and shear resistance. It is suitable for large-span or heavy decorative panels (such as stone and metal panels). The spacing of multiple sets of hanging pieces 9 is consistent with the vertical spacing of the horizontal keel 7 and the position corresponds to ensure that the decorative panel 2 is accurately inserted into the slot 702 through the hanging piece 9, eliminating the risk of installation misalignment. The lightweight design of the aluminum alloy horizontal keel 7 and vertical keel 6 reduces the load on wall 1.
[0035] Please see Figure 2 , Figure 3 and Figure 4 The decorative panel 2 is made of environmentally friendly high-density fiberboard with a thickness of 12mm. The corner bracket 3 includes an L-shaped stainless steel metal frame 301. The L-shaped stainless steel metal frame 301 has a first through hole 302 and a second through hole 303 on its surface. The expansion bolt 4 passes through the first through hole 302, and the first screw 5 passes through the second through hole 303. The horizontal keel 7 includes a keel frame body 701. The upper end of the keel frame body 701 is provided with a slot 702. The lower end of the hanging piece 9 is engaged in the slot 702. The lower end of the keel frame body 701 is provided with a sliding groove 703. The sliding groove 703 is provided with an elastic pad 704. The elastic pad 704 is in contact with the back side of the decorative panel 2. The first screw 5 and the second screw 6 are installed in the first through hole 302 and the second through hole 703 respectively. Both screw 8 and the third screw 10 are coated with anti-rust paint. The formaldehyde emission of the high-density fiberboard is ≤0.05mg / m³ (E0 grade), which meets the indoor environmental protection standards. The density is ≥800kg / m³, and the bending strength at a thickness of 12mm is ≥30MPa. Its impact resistance is better than that of ordinary wood boards. The second through hole 303 facilitates the adjustment of the fixing position of the first screw 5 and the easy movement of the decorative panel 2 for leveling. It is suitable for uneven wall surfaces. The elastic pad 704 protects the back surface of the decorative panel 2. The anti-rust paint forms a dense protective layer on the surfaces of the first screw 5, the second screw 8 and the third screw 10, which isolates the metal from corrosive substances such as moisture, oxygen and salt spray, and avoids electrochemical reactions that cause rust.
[0036] In this embodiment, by setting up corner brackets 3, vertical keels 6, horizontal keels 7, hanging plates 9, and decorative panels 2, when workers need to install decorative panels 2, they install corner brackets 3 on the surface of wall 1 using expansion bolts 4, fix vertical keels 6 to the side of corner brackets 3 using first screws 5, fix horizontal keels 7 to the surface of vertical keels 6 using second screws 8, and hangers 9 are connected to the back of decorative panels 2 by third bolts. Then, decorative panels 2 are installed by the cooperation of hangers 9 and horizontal keels 7. This is a detachable prefabricated structure, and decorative panels 2 can be replaced later. The lightweight design of aluminum alloy horizontal keels 7 and vertical keels 6 reduces the load on wall 1, and stainless steel hanging plates 9 improve installation stability.
[0037] The working principle of the above embodiment is as follows: When the worker needs to install the decorative panel 2, the worker installs the corner bracket 3 on the surface of the wall 1 using expansion bolts 4, and fixes the vertical keel 6 to the side of the corner bracket 3 using the first screw 5. The surface of the corner bracket 3 has a second through hole 303, which facilitates the adjustment of the fixing position of the first screw 5 and the leveling of the decorative panel 2, which is suitable for uneven wall surfaces. The horizontal keel 7 is fixed to the surface of the vertical keel 6 using the second screw 8. The back side of the decorative panel 2 is connected to the hanging piece 9 by the third bolt. Then the decorative panel 2 cooperates with the horizontal keel 7 through the hanging piece 9. The decorative panel 2 is installed using a detachable prefabricated structure, allowing for future replacement. The lightweight design of the aluminum alloy horizontal keel 7 and vertical keel 6 reduces the load on the wall 1. The stainless steel hanging plate 9 improves installation stability. The decorative panel 2 is made of environmentally friendly high-density fiberboard, ensuring the material's environmental performance. The anti-rust paint forms a dense protective layer on the surfaces of the first screw 5, the second screw 8, and the third screw 10, isolating the metal from corrosive substances such as moisture, oxygen, and salt spray, and preventing electrochemical reactions that could cause corrosion. The elastic pad 704 protects the back surface of the decorative panel 2.
