Description

Technical Field

[0001] This invention relates to an integrated aluminum profile ceiling and decorative wall structure, belonging to the field of building decoration technology. Background Technology

[0002] As the building decoration industry transforms towards green, low-carbon, efficient, and convenient practices, traditional ceiling and wall decoration construction methods are no longer able to meet diversified needs, high-efficiency standards, and cost control requirements. The industry urgently needs modular and integrated technical solutions to address these pain points.

[0003] As core elements of spatial beautification and functional optimization, the construction techniques and material applications of ceilings and walls directly affect project efficiency, cost, effect, and subsequent maintenance.

[0004] In traditional construction, ceilings are often made by splicing together loose panels, lacking dedicated profile support. This requires a lot of on-site cutting and sanding, making the process cumbersome and prone to problems such as uneven and rough seams, uneven edges, and environmental impact. There is also serious interference between processes, which affects the construction progress. Wall decoration faces similar difficulties. The treatment of inside and outside corners relies on manual operation, which lacks precision. The baseboards are not tightly connected and are prone to loosening and falling off, which not only affects the overall aesthetics but also increases maintenance costs.

[0005] Although some decorations currently use profiles installed between adjacent panels, their main function is to block and seal the gaps between the panels, and the panels are still directly fixed to the wall.

[0006] Currently, some decorative panels use silica fume decorative boards, achieving an A1 fire rating (non-combustible), with no formaldehyde release and low VOCs, making them environmentally friendly. They are lightweight, strong, moisture-resistant, weather-resistant, and durable. The surface is smooth, wear-resistant, stain-resistant, highly decorative, and easy to maintain. The product can be sawed, nailed, bent, and carved. Applications include interior walls, ceilings, whole-house customization, exterior curtain walls, and various public spaces such as hospitals, schools, and libraries. Compared to calcium silicate boards, gypsum boards, and traditional wood panels, this product has significant advantages in environmental friendliness, load-bearing capacity, structural toughness, moisture and fire resistance, and service life. Installation can use a light steel keel or metal frame as the base layer, and subsequent daily maintenance is simple.

[0007] However, this silica-based gray silica decorative panel also has some shortcomings:

[0008] (1) Its weight is greater than that of traditional gypsum board and wood board. Therefore, it must be fixed with fasteners and cannot be fixed with glue alone. (2) The material is too brittle. Corners or edges need to be cut, and the board is prone to chipping, which affects the appearance. (3) The market price is too high, and if it is damaged or chipped, the economic cost will be high; (4) The performance of the high-density and low-density areas of the board is significantly different: the nail holding performance of the high-density area is good, while the low-density area is easy to loosen when nailed directly or when fixed with self-tapping screws, and the probability of damage is higher when drilling screw holes.

[0009] Therefore, although the above-mentioned decorative panels have a good effect, they are not easy to drill holes for fixing or cutting. The panels are heavy and the nailing method is cumbersome, which leads to high labor costs for on-site installation (if the panel is damaged, it will cause multiple manual handling and waste of effort), which directly affects the on-site construction effect. Summary of the Invention

[0021] This invention is based on the upgrading and integration of existing decorative profile technology. It uses specialized decorative profiles as the core to construct an integrated ceiling and decorative wall system. This is not only an inevitable choice to keep up with industry trends, but also an important study to improve the quality and efficiency of engineering projects.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention employs an integrated technology combining multiple profiles, offering significant advantages and comprehensively addressing the pain points of traditional decorative wall (display wall) construction, as detailed below: 1. Simplified installation process and improved construction efficiency. Traditional construction requires highly skilled personnel, involves overlapping procedures and repeated adjustments, and is time-consuming and labor-intensive. This invention, through standardized and modular panel design, allows for prefabrication in the factory, requiring only snap-fit ​​connections on-site. This facilitates installation without the need for extensive cutting and grinding, reducing panel damage caused by drilling, trimming, or grinding during installation, thus lowering the panel damage rate and saving both material and labor costs. Precise fit for various edge trims and corner profiles (i.e., single-sided, double-sided, inside corner, and outside corner profiles) avoids process interference, reduces repeated calibration, significantly improves installation efficiency, and shortens the construction cycle.

[0023] 2. Modular configuration ensures reasonable structure and strong controllability of the construction period. The entire system adopts a modular configuration, with all panels and profiles manufactured in a standardized factory, ensuring precise dimensions and stable quality, avoiding dimensional deviations and uneven quality issues during on-site processing. Modules can be adjusted on-site according to spatial layout and decoration requirements without complex adjustments, reducing construction waiting time and waste. The construction period can be accurately calculated, shortening the time by 30%-50% compared to traditional methods, adapting to tight project needs and ensuring on-time delivery.

[0024] 3. Reduced labor costs and significant economic benefits. Traditional construction requires highly skilled professional workers, resulting in high labor input and costs. The modular splicing technology of this invention is easy to operate, and ordinary workers can be put to work after simple training, reducing reliance on professional workers and the number of construction personnel. At the same time, construction efficiency is improved, the construction period is shortened, further reducing the time spent on labor input. Combined with reduced construction losses, this comprehensively reduces the overall project cost and enhances market competitiveness.

[0025] 4. Reliable decorative quality, balancing aesthetics and practicality. Traditional construction relies on manual labor, which easily leads to various problems such as splicing, edge finishing, and treatment of inside and outside corners, affecting aesthetics and service life. This invention uses specialized profiles (i.e., single-sided profiles, double-sided profiles, inside corner profiles, and outside corner profiles) to effectively cover splicing gaps, standardize inside and outside corner lines, and achieve a tight connection between walls, floors, and ceilings, improving the overall integrity and aesthetics of the decorative space; the built-in shelves and cabinets in the decorative wall are deeply integrated with the profiles, optimizing space utilization, balancing decoration and practicality, and also providing a display effect, enhancing the user experience.

[0026] 5. Highly adaptable, environmentally friendly, and aligned with industry trends. The profiles used in this invention are made of high-quality environmentally friendly materials such as aluminum-magnesium-manganese alloy, which are high-strength, corrosion-resistant, lightweight, recyclable, and release no harmful substances, meeting green and low-carbon requirements. The modular design can flexibly adapt to various scenarios such as commercial complexes and office buildings, and can be flexibly adjusted according to decoration style and space size. At the same time, it reduces on-site dust, noise pollution, and construction losses, achieving an organic combination of high efficiency and environmental protection, which aligns with the industry's modular, integrated, and green development direction.

[0027] This invention integrates various specialized decorative profiles to construct an integrated system: the ceiling uses ceiling splicing and edge trim profiles, the wall uses matching wall panel splicing, inside and outside corner and edge trim profiles, and the bottom combines exposed and concealed skirting board profiles to achieve standardized splicing and edge trim.

[0028] This invention not only effectively solves the pain points of traditional construction methods, such as low integration, low efficiency, and difficulty in cost control, but also relies on mature profile production processes and modular concepts. Drawing on industry advantages and optimizing for practical applications, it can be widely used in various indoor and outdoor decoration projects, demonstrating outstanding practicality and promotional value. Its application can also help the industry reduce construction pollution, promote the transformation and upgrading of the building decoration industry towards low-carbon, high-efficiency, and environmentally friendly directions, and provide new ideas and practical cases for technological progress in the industry.

[0029] This invention effectively avoids construction defects such as direct nailing, single-point screw fixing, and cracking due to gaps in panel splicing by using a variety of special profiles for connection and fixation.

[0030] This invention uses a metal frame as a fixed skeleton, which is fixed to the construction wall, floor, or slab. The metal frame can also be used as a wall, directly fixed to the floor in the center of the room as a partition wall, suitable for various architectural decorations and display walls. Each profile is fixed to the metal frame, thus changing the original method of directly fixing the panel to profile fixing. The panel is confined between two adjacent profiles; that is, the panel is merely snapped between the profiles and not directly fixed to the metal frame. No screw holes are provided on the panel, avoiding damage caused by drilling. If the panel at the edge is chipped due to cutting, the chipped area can be covered by the snapping of the profiles, achieving aesthetics and reducing the problem of rendering the panel unusable due to chipping.

Detailed Implementation

[0032] To make the present invention more apparent and understandable, preferred embodiments are described in detail below with reference to the accompanying drawings.

[0033] This invention provides an integrated aluminum profile ceiling and decorative wall structure, such as... Figures 1-10 As shown, it consists of a metal frame, profiles at various locations (i.e., single-sided profile 3, double-sided profile 6, internal corner profile 7, external corner profile 8), and panels 1. The metal frame is fastened to the ground and / or wall with screws. The metal frame includes multiple metal columns 2 fixed to the ground, and metal rods 1 connected or welded to each metal column 2 with screws. The metal rods 1 are arranged horizontally; they can also be arranged crosswise to better fix the metal columns 2 and enhance the overall structural strength. Multiple metal rods 1 can also be fixed to the wall or floor slab with screws to further increase the overall structural strength. In this embodiment, the metal rods 1 can be steel or aluminum profiles. Each panel 1 is fixed to the metal frame only by the limiting snaps of each profile, without any other structural connection to the metal frame. The panels 1 are standardized and modularly customized. Note: If the size of individual locations (such as corners) is not the standard size, it needs to be cut as needed.

[0034] like Figure 2 As shown, the metal frame is located on the outer edge of a single side (for wall panels) at the location of doors, windows, cabinets, etc., and is fastened to the single-sided profile 3 by screws 5. The single-sided profile 3 has a panel groove that opens in the opposite direction to the door, window, cabinet, etc., for inserting the panel 4.

[0035] like Figure 3 As shown, the single-sided profile 3 includes a bent edge 31. One side of the bent edge 31 is connected to a first inner edge 33. The first inner edge 33 is parallel to the other side of the bent edge 31, and the two form a panel groove for inserting the panel 4, namely the first panel groove 36. The first inner edge 33 has small holes for screws 5 to be fixed on the metal frame.

[0036] In this embodiment, the extension of one side of the bent edge 31 connected to the first inner edge 33 is connected to the first short edge 32; the first inner edge 33 is provided with a first abutting protrusion 34 at the installation position of the screw 5, that is, the first inner edge 33 at the installation position of the screw 5 forms a truncated cone-shaped protrusion towards the metal frame, so that the side of the first inner edge 33 away from the metal frame forms a truncated cone-shaped first screw groove 35, and the height of the first abutting protrusion 34 relative to the first inner edge 33 is the same as the height of the first short edge 32 relative to the first inner edge 33; the bent edge 31 is a right-angle bent edge.

[0037] Among them, the edge of the bending edge 31 located at the opening of the first panel groove 36 gradually becomes smaller in order to reduce the height difference between it and the panel 4, and the edge is rounded and smooth, so as to achieve the functions of aesthetics and preventing bumps and cuts.

[0038] like Figure 4 As shown, a metal frame is located in the middle of the wall panel and the middle of the ceiling, and is fastened to multiple double-sided profiles 6 at intervals by screws 5. Each of the opposite sides of the double-sided profile 6 is provided with a panel groove for inserting a panel 4.

[0039] like Figure 5 As shown, the double-sided profile 6 includes an outer pressing long side 61, with one end of the middle side 65 connected to the middle position of the outer pressing long side 61, and the other end of the middle side 65 connected to the middle position of the second inner side 64. The outer pressing long side 61 and the second inner side 64 are parallel to each other. Panel grooves for inserting the panel 4, namely the second panel grooves 67, are formed on both sides of the middle side 65 between the outer pressing long side 61 and the second inner side 64. A small hole for fixing the screw 5 to the metal frame is opened on one side of the middle side 65 on the second inner side 64.

[0040] In this embodiment, the end of the second inner edge 64 located on the other side of the middle edge 65 is connected to the second short edge 66; the second inner edge 64 is provided with a second abutting protrusion 63 at the mounting position of the screw 5, that is, the second inner edge 64 at the mounting position of the screw 5 forms a truncated cone-shaped protrusion towards the metal frame, so that the side of the second inner edge 64 away from the metal frame forms a truncated cone-shaped second screw groove 62, and the height of the second abutting protrusion 63 relative to the second inner edge 64 is the same as the height of the second short edge 66 relative to the second inner edge 64; the middle edge 65 is perpendicular to the outer pressure long edge 61 and the second inner edge 64 respectively.

[0041] Among them, the two ends of the outer pressure long side 61 located at the opening of the second panel groove 67 gradually become smaller in order to reduce the height difference between it and the panel 4. The edges are rounded and smooth, which achieves the functions of aesthetics and preventing bumps and cuts.

[0042] like Figure 6 As shown, the metal frame located at the inside corner (including the inside corner of the side and the inside corner of the ceiling recess) is fastened to the inside corner profile 7 by screws 5. Each of the adjacent sides of the inside corner profile 7 is provided with a panel groove for inserting the panel 4.

[0043] like Figure 7As shown, the inside corner profile 7 includes an inside corner frame 71. Two adjacent straight edges of one corner of the inside corner frame 71 extend toward the corner to form an outer short edge 1 76 and an outer short edge 2 77. The two adjacent straight edges are connected to the inside corner edge 79 and the third inside edge 72 respectively at positions away from the corner. The outer short edge 2 77 is parallel to the inside corner edge 79, and the outer short edge 1 76 is parallel to the third inside edge 72. A panel groove for inserting the panel 4 is formed between the outer short edge 2 77 and the inside corner edge 79, and between the outer short edge 1 76 and the third inside edge 72, respectively. The third inside edge 72 has small holes for fixing the screws 5 to the metal frame.

[0044] In this embodiment, the internal corner frame 71 is a square structure, i.e., a square frame. A third short side 78 is connected to the end of the internal corner frame 79 away from the internal corner frame 71. A third abutting protrusion 73 is provided on the third internal side 72 at the mounting position of the screw 5, i.e., a frustum-shaped protrusion is formed on the third internal side 72 towards the metal frame at the mounting position of the screw 5, thus forming a frustum-shaped third screw recess 74 on the side of the third internal side 72 away from the metal frame. The height of the third abutting protrusion 73 relative to the third internal side 72 is the same as the height of the side of the internal corner frame 71 closest to the metal frame relative to the third internal side 72. This side of the internal corner frame 71 closest to the metal frame is parallel to the first external pressure short side 76. The height of the third short side 78 relative to the internal corner frame 79 is the same as the height of the other side of the internal corner frame 71 closest to the metal frame relative to the internal corner frame 79. This other side of the internal corner frame 71 closest to the metal frame is parallel to the second external pressure short side 77.

[0045] Among them, the outer short edge 76 and the third inner edge 72 are located at the opening positions of the corresponding third panel groove 75, and the edges gradually become smaller in order to reduce the height difference between them and the panel 4. The edges are rounded and smooth, which achieves the functions of aesthetics and preventing bumps and cuts.

[0046] like Figure 8 As shown, the metal frame is located at the external corner (including the external corner of the side and the external corner of the ceiling recess) and is fastened to the external corner profile 8 by screws 5. Each of the adjacent sides of the external corner profile 8 is provided with a panel groove for inserting the panel 4.

[0047] like Figure 9As shown, the external corner profile 8 includes an external short side 3 81 and an external short side 4 82. One end of the external short side 3 81 is connected to one end of the external short side 4 82. The connection point between the external short side 3 81 and the external short side 4 82 is also connected to one end of the partition 83. The other end of the partition 83 is connected to one end of the internal side 84 and one end of the fourth internal side 86. The external short side 3 81 and the fourth internal side 86 are parallel to each other, and the external short side 4 82 and the internal side 84 are parallel to each other. A panel groove for inserting the panel 4, namely the fourth panel groove 89, is formed between the external short side 3 81 and the fourth internal side 86, and between the external short side 4 82 and the internal side 84. The fourth internal side 86 has small holes for screws 5 to be fixed on the metal frame.

[0048] In this embodiment, the outer short side 3 81 and the outer short side 4 82 are perpendicular to each other, forming a right angle. The other end of the inner side 84 of the external corner is connected to the fourth short side 85; the fourth inner side 86 is provided with a fourth abutting protrusion 87 at the installation position of the screw 5, that is, the fourth inner side 86 at the installation position of the screw 5 forms a frustum-shaped protrusion towards the metal frame side, so that the side of the fourth inner side 86 away from the metal frame forms a frustum-shaped fourth screw groove 88; the height of the fourth abutting protrusion 87 relative to the fourth inner side 86 is the same as the height of the fourth short side 85 relative to the inner side 84 of the external corner, that is, the distance from the fourth inner side 86 to one side of the metal frame is the same as the distance from the inner side 84 of the external corner to the other side of the metal frame.

[0049] Among them, the edges of the outer short edge 3 81 and the outer short edge 4 82 at the opening positions of the corresponding fourth panel groove 89 gradually become smaller in order to reduce the height difference between them and the panel 4. The edges are rounded and smooth, which achieves the functions of aesthetics and preventing bumps and cuts.

[0050] like Figure 10 As shown, the single-sided profile 3 can also be used at the inside corner where the included angle between the wall panels is greater than 90 degrees, by using two single-sided profiles 3 as mounting components for the end panels 4.

[0051] Among them, single-sided profile 3, double-sided profile 6, internal corner profile 7, and external corner profile 8 are all integrally formed structures. Screw 5 is a bolt (the position on the metal frame where screw 5 is connected has a threaded hole that matches the external thread of screw 5) or a self-tapping screw.

[0052] Depending on the needs of the decoration location, each panel 4 can be paired with any two of the following: single-sided profile 3, double-sided profile 6, inside corner profile 7, outside corner profile 8, or two of the same type.

[0053] In this embodiment, the first panel groove 36, the second panel groove 67, the third panel groove 75, and the fourth panel groove 89 are all matched with the thickness of the panel 4; the depth of the frustum-shaped (large opening and small bottom) of the first screw recess 35, the second screw recess 62, the third screw recess 74, and the fourth screw recess 88 is not less than the height of the large end of the screw 5, and the diameter of the small round end of the frustum-shaped groove is not less than the maximum diameter of the large end of the screw 5.

[0054] In this embodiment, all profiles are made of high-hardness aluminum profiles, and their outer surfaces must be smooth, free of burrs and sharp edges; their length direction must be straight, upright, and free of twisting. Specifically, the material of the profiles can be Al 6063 or other grades; the hardness is ≥HRB28. More preferably, the optimal hardness is ≥HRB60.

[0055] In another embodiment, the inside corner position of the inside corner profile 7 and the outside corner position of the outside corner profile 8 are structures with angles other than right angles.

[0056] In another embodiment, the various profiles and the metal frame can be further secured by applying adhesive (e.g., silicone sealant) at the fixing points of the screws 5, increasing their reliability. Preferably, the adhesive can be located between the profiles and the metal frame, thereby increasing the shock absorption effect of the panel 4.

[0057] In another embodiment, a skirting board profile (similar to a single-sided profile 3) is also fixed on the ground to wrap around the bottom edge of the panel 1. The skirting board profile can be an upward-opening U-shaped structure, which not only increases the aesthetics but also serves as a limit for the bottom of the panel 1, making the panel 1 more securely confined to the outside of the metal frame. The panel 1, which serves as the inner wall surface, is also connected to the top ceiling by a corner profile 7, which also increases the secure confinement of the panel 1 to the outside of the metal frame.

[0058] The construction process of this invention is as follows: First, securely connect the metal frame to the base (or the base and the wall). Then, install one profile (one of the following: single-sided profile 3, double-sided profile 6, internal corner profile 7, or external corner profile 8) as needed. Next, insert one end of panel 4 into the corresponding panel groove. Then, insert the panel groove of another profile into the other end of the previous panel 4, and fix the profile to the metal frame. Repeat this process. After the last panel 4 is placed, fix the remaining profile (one of the following: single-sided profile 3, internal corner profile 7, or external corner profile 8) to the metal frame using adhesive (e.g., silicone sealant).

[0059] When installing panel 4 on the ceiling, use the same construction steps as on the wall: first install one profile, then place panel 4, and then install another profile.
