Description

Technical Field

[0001] This utility model relates to the field of interior decoration technology, and in particular to a prefabricated decorative surface structure. Background Technology

[0002] Prefabricated interior decoration uses a lightweight steel keel support system to construct a lightweight partition wall system, achieving flexible space division and pipeline integration. This construction method has advantages such as quick installation and reusability. When decorating the wall, multiple keels are usually fixed to the wall first, and then the decorative panels are hung on the keels to achieve rapid assembly and facilitate quick removal and replacement later. However, the existing decorative panel assembly method has obvious technical defects: First, since multiple decorative panels need to be installed on each wall, obvious gaps often appear between adjacent decorative panels after assembly. This not only seriously affects the overall aesthetic effect of the wall, but also makes it easy for dust and debris to accumulate in the cavity between the original wall structure and the decorative wall panel, and may even damage the pre-embedded pipeline structure in the wall due to water ingress and moisture. Utility Model Content

[0003] The main purpose of this utility model is to propose an assembled decorative surface structure, which aims to improve the sealing degree between decorative panels.

[0004] To achieve the above objectives, the prefabricated decorative surface structure proposed in this utility model includes:

[0005] Multiple keels are installed on the wall. The multiple keels are arranged horizontally and vertically spaced apart. Each keel is provided with an upward-facing first hook part, and a first guide is provided on the inner side of the first hook part.

[0006] The decorative panel has multiple hooks on one side, each hook having a downward-facing second hook portion. The inner side of the second hook portion has a second guide. During the process of the second hook portion hooking the first hook portion, the second guide is guided by the first guide, causing the decorative panel to slide to one side and press against the adjacent decorative panel for a tight connection.

[0007] In one embodiment, the keel includes:

[0008] A first mounting plate is provided at a distance from the first hook portion. The first mounting plate is connected to the wall via a connector. The first mounting plate is positioned higher than the first hook portion to facilitate the installation of the connector and to prevent the first mounting plate from being blocked by the first hook portion during installation.

[0009] A first connecting plate is used to connect the first mounting plate and the first hook part.

[0010] In one embodiment, the top of the first mounting plate is provided with a guide slope.

[0011] In one embodiment, the first mounting plate is mounted to the wall by expansion screws, the expansion screws being higher than the first hook portion.

[0012] In one embodiment, the hook member includes:

[0013] The second mounting plate is installed on one side of the decorative panel, and the second mounting plate is spaced apart from the second hook portion.

[0014] The second connecting plate is used to connect the second mounting plate and the second hook part.

[0015] In one embodiment, both the first guide and the second guide are guide slats.

[0016] In one embodiment, the first guide is located at the top of the first connecting plate, and the second guide is located at the bottom of the second connecting plate, so that the first connecting plate and the second connecting plate are hidden.

[0017] In one embodiment, the first guide includes a first inclined rod and a first straight rod, the first inclined rod being located above the first straight rod;

[0018] The second guide includes a second inclined rod and a second straight rod, with the second inclined rod located below the second straight rod;

[0019] After the second inclined rod is guided by the first inclined rod, the second straight rod and the first straight rod come into contact, completing the extrusion positioning of the decorative panel.

[0020] In one embodiment, the keel is a light steel keel.

[0021] In one embodiment, sealing strips are provided on both sides of the decorative panel.

[0022] This application provides a prefabricated decorative surface structure and its keel and decorative panels. By setting mutually cooperating guide components and hook structures, the decorative panels can automatically slide and tightly squeeze adjacent decorative panels during installation, effectively solving the gap problem between decorative panels. At the same time, it improves the installation accuracy and connection strength. Moreover, the connection structure adopts a hidden design, which significantly improves the overall aesthetics.

[0035] Please see Figures 1 to 5 This application proposes a prefabricated decorative surface structure 1000, including multiple keels 1 and decorative panels 2. The keels 1 are installed on the wall 5, and the multiple keels 1 are arranged horizontally and vertically at intervals. Each keel 1 has an upward-facing first hook portion 11, and a first guide member 14 is provided on the inner side of the first hook portion 11. Each decorative panel 2 has multiple hook members 3 on one side, and each hook member 3 has a downward-facing second hook portion 31. A second guide member 34 is provided on the inner side of the second hook portion 31. During the process of the second hook portion 31 hooking the first hook portion 11, the second guide member 34 is guided by the first guide member 14, causing the decorative panel 2 to slide to one side and press against the adjacent installed decorative panel 2 for a tight connection.

[0036] The keel 1 can be made of metal or plastic, preferably light steel keel. The first hook part 11 can be designed as L-shaped, U-shaped, or other shapes suitable for hooking. The first guide member 14 can be a guide slat, guide groove, or guide protrusion. The hook member 3 of the decorative panel 2 can be integrally formed on the side of the decorative panel 2, or it can be fixed by welding, riveting, or other methods. The second guide member 34 can adopt a structural form that matches the first guide member 14, such as a slat or roller. The decorative panel 2 can be made of wood, metal, or composite materials, and sealing strips 21 can be provided on both sides to enhance the connection sealing.

[0037] This technical solution, through the establishment of mutually cooperating guide structures, achieves automatic guidance and positioning during the installation of decorative panels 2, ensuring a tight, pressed connection between adjacent decorative panels 2, effectively solving the problem of gaps between decorative panels 2 in existing technologies. Specifically, when the second guide member 34 slides along the first guide member 14, the decorative panel 2 undergoes lateral displacement, thereby forming a tight contact with adjacent decorative panels 2. This structural design ensures both ease of installation and airtightness of the connection points, preventing dust and moisture from entering the gap between the decorative panel 2 and the wall surface 5. Compared with existing technologies, this solution significantly improves the integrity and aesthetics of the decorative surface while maintaining the advantages of prefabricated installation.

[0038] Furthermore, this application also proposes that the keel 1 includes a first mounting plate 12 and a first connecting plate 13. The first mounting plate 12 is spaced apart from the first hook portion 11. The first mounting plate 12 is connected to the wall surface 5 via a connector. The first mounting plate 12 is positioned higher than the first hook portion 11 to facilitate the installation of the connector and to prevent the first mounting plate 12 from being blocked by the first hook portion 11 during installation. The first connecting plate 13 is used to connect the first mounting plate 12 and the first hook portion 11.

[0039] The first mounting plate 12 can be fixed to the wall 5 using expansion bolts, chemical anchors, or nails. A guide ramp 15 can be provided at the top of the first mounting plate 12 to facilitate guidance during the installation of the decorative panel 2. The first connecting plate 13 can be made of bent steel plate with a thickness of 0.8-1.2 mm and a width of 30-50 mm. The distance between the first mounting plate 12 and the first hook portion 11 is 15-25 mm to ensure sufficient installation space for the connectors. As a preferred embodiment, the first mounting plate 12 is made of galvanized steel plate with a thickness of 1.0 mm and a width of 40 mm.

[0040] Specifically, by setting a first mounting plate 12 that is higher than the first hook part 11, the problem of insufficient installation space for the connectors is solved. A first connecting plate 13 connects the first mounting plate 12 and the first hook part 11 into a single unit, forming a stable support structure. Thus, while ensuring the structural strength of the keel 1, interference from the first hook part 11 with the installation of the connectors is avoided. The connection method between the first mounting plate 12 and the wall surface 5 can be selected according to actual construction conditions; for example, expansion bolts can be used on concrete walls 5, and self-tapping screws can be used on lightweight partition walls. This structural design makes the installation of the keel 1 more convenient and improves construction efficiency.

[0041] Furthermore, this application also proposes that the top of the first mounting plate 12 is provided with a guide slope 15.

[0042] The guide slope 15 refers to the inclined surface machined on the top of the first mounting plate 12. This slope can be designed as a straight line or an arc, and the preferred inclination angle is 15-45 degrees. In specific implementations, the guide slope 15 can be achieved by stamping, milling, or welding an inclined plate. As a preferred embodiment, a rounded transition is used between the guide slope 15 and the first connecting plate 13 to avoid stress concentration.

[0043] This technical solution, by setting a guide ramp 15 on the top of the mounting plate, allows the decorative panel 2 to slide smoothly along the ramp during installation, effectively solving the problem of jamming when the decorative panel 2 is connected to the keel 1. The guide ramp 15 works in conjunction with the first guide member 14; after the second guide member 34 contacts the first guide member 14, the decorative panel 2 can slide naturally down the ramp to the predetermined position, thereby achieving a tight connection between adjacent decorative panels 2. Compared with the existing planar contact installation method, this design significantly improves the smoothness of the assembly process and the positioning accuracy, while reducing gap problems caused by misalignment.

[0044] Furthermore, this application also proposes that the first mounting plate 12 is mounted to the wall 5 by expansion screws, with the expansion screws being higher than the first hook portion 11.

[0045] Specifically, in one implementation of the expansion screw as a connector, its installation position is limited to above the first hook portion 11. This technical feature can be achieved by: after drilling a hole in the wall surface 5, fully embedding the sleeve portion of the expansion screw into the hole, so that the screw head protrudes from the wall surface 5 but does not exceed the height of the first mounting plate 12; or by using an extended expansion screw, so that its fixing end extends deep into the wall while the exposed portion remains in the space above the first hook portion 11. As another implementation, mounting hole positions can be preset in the first mounting plate 12, and the hole positions are distributed to avoid the vertical projection area of ​​the first hook portion 11, ensuring that the force application points of all expansion screws are located at a high position.

[0046] Therefore, this technical solution solves the installation interference problem through spatial misalignment design. When the operator uses power tools to tighten the expansion bolts, the tool will not collide with the first hook part 11; during the subsequent installation of the decorative panel 2, the protrusion of the expansion bolt will not obstruct the sliding trajectory of the second hook part 31. This structural design ensures both a firm connection between the keel 1 and the wall and smooth guidance during the assembly of the decorative panel 2, effectively avoiding the problem of reduced assembly accuracy caused by installation space conflicts.

[0047] Furthermore, this application proposes that the hook member 3 includes a second mounting plate 32 and a second connecting plate 33. The second mounting plate 32 is mounted on one side of the decorative panel 2 and spaced apart from the second hook part 31; the second connecting plate 33 is used to connect the second mounting plate 32 and the second hook part 31. This technical solution achieves a reliable connection between the decorative panel 2 and the keel 1 by setting independent structures for the second mounting plate 32 and the second connecting plate 33. The fixing method between the second mounting plate 32 and the decorative panel 2 can be selected as mechanical connection or adhesive bonding according to actual needs, providing installation flexibility; the second connecting plate 33 uses standardized components, facilitating mass production. Compared with the integral hook structure, this split design reduces processing difficulty, and by optimizing the connecting plate structure, ensures the guiding accuracy and connection strength of the decorative panel 2 during sliding installation. This solution effectively solves the positioning deviation problem caused by deformation of the connecting parts during the assembly of the decorative panel 2, improving assembly efficiency and connection reliability.

[0048] Furthermore, this application proposes that both the first guide member 14 and the second guide member 34 are guide slats. The guide slats can be made of metal or plastic, and their cross-sectional shape can be triangular, trapezoidal, or other geometric shapes with bevels. Specifically, the inclination angle of the guide slats can be adjusted within the range of 30° to 60° to accommodate the installation requirements of decorative panels 2 of different sizes. As a preferred embodiment, the surface of the guide slats can be provided with anti-slip textures or a coating to enhance frictional stability during the guiding process.

[0049] In the specific implementation process, the guide strips can be connected to the first connecting plate 13 and the second connecting plate 33 by welding, riveting or bolting. The first guide 14 is set at the top of the first connecting plate 13, and the second guide 34 is set at the bottom of the second connecting plate 33. This top-to-bottom layout allows the connecting plate structure to be completely hidden at the joint between the decorative panel 2 and the keel 1.

[0050] This technical solution achieves precise guidance and positioning of the decorative panel 2 during installation through a standardized guide bar structure. When the second guide member 34 slides along the first guide member 14, the interaction of the inclined surfaces generates a horizontal component force, pushing the decorative panel 2 towards the installed panel until it reaches the preset tight connection position.

[0051] Furthermore, this application proposes that the first guide member 14 is located at the top of the first connecting plate 13, and the second guide member 34 is located at the bottom of the second connecting plate 33, so that the first connecting plate 13 and the second connecting plate 33 are concealed. The first guide member 14 includes a first inclined rod 141 and a first straight rod 142, with the first inclined rod 141 located above the first straight rod 142; the second guide member 34 includes a second inclined rod 341 and a second straight rod 342, with the second inclined rod 341 located below the second straight rod 342; the second inclined rod 341 is first guided by the first inclined rod 141, and then the second straight rod 342 contacts the first straight rod 142 to complete the extrusion positioning of the decorative plate 2.

[0052] Specifically, the angles of the first inclined rod 141 and the second inclined rod 341 are designed to match each other, enabling a smooth transition during the installation of the decorative panel 2. The first straight rod 142 and the second straight rod 342 are made of rigid metal, and their contact surfaces are polished to reduce the coefficient of friction. In a preferred embodiment, the angle between the first inclined rod 141 and the horizontal plane is 30-45 degrees, and the inclination direction of the second inclined rod 341 forms a mirror-symmetric structure with the first inclined rod 141. During installation, the decorative panel 2 is first inserted at a 15-degree inclination angle. The horizontal component force generated by the contact of the inclined surfaces between the rods pushes the decorative panel 2 laterally until the straight rods contact and lock.

[0053] Therefore, this technical solution achieves precise positioning and tight connection of decorative panels 2 through a two-stage guiding mechanism. After the inclined rod group completes the initial guidance and lateral displacement, the straight rod group forms a rigid contact surface, effectively eliminating the assembly gap between decorative panels 2. Compared with the existing single-inclined guide structure, this design, while maintaining ease of installation, ensures zero-gap fit between adjacent decorative panels 2 through mechanical limiting, solving the technical problem of easy dust accumulation and water seepage at the joints of traditional prefabricated wall panels 5.

[0054] Furthermore, this application also proposes that sealing strips 21 are provided on both sides of the decorative panel 2.

[0055] The sealing strip 21 can be made of flexible materials such as rubber, silicone, or foamed polyethylene, and is fixed to the side of the decorative panel 2 by adhesive or clips. In practice, the sealing strip 21 can be designed with a U-shaped cross-section to cover the edge of the decorative panel 2, or it can be a flat strip structure directly pasted to the side. After adjacent decorative panels 2 are installed, the sealing strips 21 on both sides are pressed together to form a continuous sealing interface. The thickness of the sealing strip 21 is preferably 3-5mm, and the compression rate is controlled at 30%-50% to ensure a good sealing effect.

[0056] This technical solution involves installing sealing strips 21 on both sides of the decorative panel 2. When multiple decorative panels 2 are assembled via the keel 1, the sealing strips 21 between adjacent decorative panels 2 undergo elastic deformation and abut against each other. Specifically, when the decorative panel 2 slides and is pressed together by the second guide member 34 and the first guide member 14, the sealing strips 21 simultaneously undergo compression deformation, thereby filling the assembly gaps between the decorative panels 2. This effectively solves the problem of dust and moisture easily entering the joints of the decorative panels 2 in the prior art, while avoiding appearance defects caused by obvious joints. Compared with structures without sealing strips 21, this solution significantly improves the sealing performance and visual integrity of the decorative surface while maintaining the advantage of rapid assembly.

[0057] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
