Description

Technical Field

[0001] This invention relates to the field of prefabricated decorative wall panel technology, and more specifically, to a prefabricated decorative wall panel system and its installation method. Background Technology

[0002] Currently, the grooves of prefabricated interior wall panels are mainly of the double female groove, male and female groove, and interlocking style. This type of groove is convenient for fixing with profile strips, but it requires one panel to be installed on top of another, and it cannot achieve the removal of individual panels. If a panel in the wall is damaged and needs to be replaced, all the panels in front of this panel must be removed before replacement, which is time-consuming, labor-intensive, and very inconvenient for maintenance.

[0003] The installation of prefabricated interior wall panels currently falls into two main categories: those requiring leveling and those not requiring leveling. In cases where leveling is not required, installers directly screw the edge trim strips on both sides of the wall panel to the base wall before installing the decorative wall panel. In cases requiring leveling, leveling screws and leveling joists are used to achieve point and line leveling, then the edge trim strips are directly screwed to the leveling joists before installing the wall panel.

[0004] The current wall panel installation requires a starting point to be determined. The four walls of a room must be fixed one by one in sequence. The installation of the finishing panels is complicated, and the wall panels cannot be installed on one side only. It has high requirements for construction procedures and processes, and the wall panels are very difficult to maintain later. If a wall panel in the middle is damaged, the previous wall panels must be removed in sequence to replace it. Moreover, the current wall panels are fixed by using profiles to press and clamp the wall panel grooves on both sides. The wall panels are interlocked with each other. If a single wall panel is damaged, it cannot be removed piece by piece. It must be disassembled and replaced from the front.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Summary of the Invention

[0006] To address the shortcomings of existing technologies, the purpose of this invention is to propose a prefabricated decorative wall panel system and its installation method.

[0007] To achieve the above objectives, the present invention provides a prefabricated decorative wall panel system, comprising an installation keel, elastic alloy fasteners, and a wall panel body. The installation keel has a U-shaped groove. The elastic alloy fastener consists of a flat plate and a zigzag side plate, with the two sides of the flat plate integrally connected to the zigzag side plate. Both ends of the wall panel body have snap-fit ​​grooves. A fastener positioning structure is provided on one side of the snap-fit ​​groove on the wall panel body. Inner grooves are formed on both sides of the U-shaped groove on the installation keel. A wall panel positioning structure that mates with the inner groove is provided on the wall panel body.

[0008] Preferably, the fastener positioning structure includes a semi-circular groove on the side of the wall panel body, a positioning plate is provided outside the semi-circular groove, a side plate snap-fit ​​groove is provided on the positioning plate, and an arc-shaped elastic metal sheet is provided outside the side plate snap-fit ​​groove.

[0009] Preferably, the positioning plate is fixedly provided with a connecting block on one side of the semi-circular groove, and a movable rod is movably connected to the connecting block via a rotating shaft. The other end of the movable rod is movably connected to a guide wheel, and rolling grooves matching the guide wheel are symmetrically opened on the semi-circular groove.

[0010] Preferably, the wall panel body has a communicating cavity, the connecting block is connected to a connecting post, one end of the connecting post extending into the communicating cavity is provided with a slider, and a positioning spring is connected between the slider and the inner wall of the communicating cavity.

[0011] Preferably, the wall panel positioning structure includes a protrusion integrally connected to the back of the wall panel body, a pressure block is provided above the protrusion, an inner cavity is provided inside the protrusion, a guide post is connected to the bottom of the pressure block and extends movably into the inner cavity, and a butterfly spring is provided at the bottom of one end of the guide post located in the inner cavity.

[0012] Preferably, the guide post has fixing blocks on both sides of one end located in the inner cavity. A connecting rod is movably connected to the fixing block. Placement slots are provided on both sides of the protrusion. Arc-shaped positioning pieces are provided in the placement slots. A connecting rod extending into the inner cavity is connected to the arc-shaped positioning pieces. The connecting rod movably passes through the side wall of the protrusion. The other end of the connecting rod movably connects to the connecting rod.

[0013] A method for installing a prefabricated decorative wall panel system, characterized by the following steps:

[0014] Step 1: First, connect and fix the installation keel to the wall to be decorated, and install the elastic alloy fasteners consisting of flat plates and folded side plates into the U-shaped brackets on the installation keel to complete the installation of the elastic alloy fasteners and the installation keel.

[0015] Step 2: Press the wall panel body with the snap-fit ​​groove from the front between two adjacent installation keels, so that it is limited by the wing plates on both sides of the installation keel and the lateral extrusion force of the folded side plate in the elastic alloy fastener, so that the wall panel body is leveled and fixed between the installation keels, thereby completing the wall panel installation. Then install the wall panel body one by one according to the subsequent method.

[0016] Step 3: Through the fastener positioning structure, when the wall panel body is squeezed from the front, the outer side of the folded side plate will contact the arc-shaped elastic metal sheet on the positioning plate. The side plate locking groove adapts to the deformation of the folded side plate. At this time, the positioning plate is subjected to lateral squeezing force, which will drive the connecting column to contract. This causes the movable rod to open at a certain angle under the cooperation of the guide wheel and the rolling groove. At the same time, the positioning spring provides a certain reaction force, thereby playing an auxiliary positioning effect on the side of the wall panel body.

[0017] Step 4: Setting up the wall panel positioning structure. When the wall panel body is installed, the pressure block will gradually approach the protrusion. The pressure block will drive the guide column to retract inward. The connecting rod of the fixed block and the guide column will open, thereby pushing the connecting rod to extend outward. This will make the arc-shaped positioning piece in the groove fit against the side wall of the inner groove, so that the wall panel body will not be misaligned after installation, ensuring the accuracy of the installation position of each wall panel body.

[0018] Step 5: When it is necessary to disassemble, repair or replace any wall panel, simply use the suction cup to hold the wall panel and apply an outward pulling force greater than the compressive force on both sides to move the wall panel outward, thereby disassembling the wall panel. Use the suction cup to fix the replaced wall panel and apply an inward force greater than the compressive force on both sides to move the wall panel inward until it is stuck at the rear wing edge of the keel, thus completing the replacement and installation.

[0019] This invention provides a prefabricated decorative wall panel system and its installation method, with the following beneficial effects:

[0020] The device of this application utilizes elastic alloy fasteners in conjunction with a wall panel body equipped with snap-fit ​​grooves. This allows the wall panel body to be snapped into the elastic alloy fasteners from the front while the elastic alloy fasteners are being installed with the mounting keel. The structure is simpler and the processing is easier. The wall panel body with snap-fit ​​grooves, when used with a specific keel system, can achieve front-side disassembly and assembly as well as single-panel disassembly and assembly. The installation method is more flexible, the installation logic is simpler, and the installation efficiency can be improved. Attached Figure Description

[0031] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0032] Please see Figure 1-7According to an embodiment of the present invention, a prefabricated decorative wall panel system includes an installation keel 1, elastic alloy fasteners 3, and a wall panel body 6. The installation keel 1 has a U-shaped groove 2. The elastic alloy fastener 3 consists of a flat plate 4 and a zigzag side plate 5, with the two sides of the flat plate 4 integrally connected to the zigzag side plate 5. The installation keel 1 is connected and fixed to the wall surface to be decorated. The elastic alloy fastener 3, composed of the flat plate 4 and the zigzag side plate 5, is installed in the U-shaped groove 2 on the installation keel 1, completing the installation of the elastic alloy fastener 3 and the installation keel 1. Both ends of the wall panel body 6 have snap-fit ​​grooves 7. The wall panel body 6 with the snap-fit ​​grooves 7 is pressed from the front between two adjacent installation keels 1, so that it is limited by the side flanges of the installation keel 1 and subjected to the lateral pressing force of the zigzag side plate 5 in the elastic alloy fastener 3. This allows the wall panel body 6 to be leveled and fixed between the installation keels 1, thereby completing the wall panel installation. Then, the wall panel bodies 6 are installed one by one according to the subsequent method. A fastener positioning structure 8 is provided on one side of the snap-fit ​​groove 7 on the wall panel body 6. The fastener positioning structure 8 provides auxiliary positioning for the side of the wall panel body 6. The mounting keel 1 forms inner grooves 10 on both sides of the U-shaped bracket 2. The wall panel body 6 is provided with a wall panel positioning structure 9 that cooperates with the inner groove 10. When the wall panel body 6 is installed, the wall panel positioning structure 9 ensures that the wall panel body 6 will not shift after installation, thus ensuring the accurate installation position of each wall panel body 6. The device of this application uses elastic alloy fasteners 3 in conjunction with the wall panel body 6 with snap-fit ​​groove 7. While the elastic alloy fasteners 3 are installed with the mounting keel 1, the wall panel body 6 can be snapped into the elastic alloy fasteners 3 from the front to complete the installation. The structure is simpler and the processing is easier. The wall panel body 6 with snap-fit ​​groove 7 can be used with a specific keel system to achieve front-side disassembly and single-panel disassembly. The installation method is more flexible and the installation logic is simpler, which can improve the installation efficiency.

[0033] In one embodiment, please refer to the appendix to the specification. Figure 1 , Figure 5 and Figure 6As shown, the fastener positioning structure 8 includes a semi-circular groove 11 on the side of the wall panel body 6. A positioning plate 12 is provided outside the semi-circular groove 11. A side plate snap-fit ​​groove 13 is provided on the positioning plate 12. An arc-shaped elastic metal sheet 14 is provided outside the side plate snap-fit ​​groove 13. A connecting block 15 is fixedly provided on one side of the positioning plate 12 located in the semi-circular groove 11. A movable rod 16 is movably connected to the connecting block 15 through a rotating shaft. A guide wheel 17 is movably connected to the other end of the movable rod 16. Rolling grooves 18 matching the guide wheel 17 are symmetrically provided on the semi-circular groove 11. A communicating cavity 19 is provided inside the wall panel body 6. A connecting post 20 is connected to the connecting block 15. A slider 21 is provided at one end of the connecting post 20 extending into the communicating cavity 19. A positioning spring 22 is connected between the slider 21 and the inner wall of the communicating cavity 19. Through the fastener positioning structure 8, when the wall panel body 6 is pressed from the front, the outer side of the folded side plate 5 will contact the arc-shaped elastic metal sheet 14 on the positioning plate 12. The side plate locking groove 13 adapts to the deformation of the folded side plate 5. At this time, the positioning plate 12 will be subjected to lateral pressure, which will cause the connecting column 20 to contract, so that the movable rod 16 will open at a certain angle under the cooperation of the guide wheel 17 and the rolling groove 18. At the same time, the positioning spring 22 will give a certain reaction force, thereby playing an auxiliary positioning effect on the side of the wall panel body 6.

[0034] In one embodiment, please refer to the appendix to the specification. Figure 1 and 7 As shown, the wall panel positioning structure 9 includes a protrusion 23 integrally connected to the back of the wall panel body 6. A pressure block 24 is provided above the protrusion 23. An inner cavity 25 is provided inside the protrusion 23. A guide post 26, which extends movably into the inner cavity 25, is connected to the bottom of the pressure block 24. A butterfly spring 32 is provided at the bottom of one end of the guide post 26 located within the inner cavity 25. Fixing blocks 27 are provided on both sides of the end of the guide post 26 located within the inner cavity 25. A connecting rod 28 is movably connected to the fixing block 27. Placement grooves 29 are provided on both sides of the protrusion 23. An arc-shaped positioning piece 30 is provided within the placement groove 29. The arc-shaped positioning piece 30... A second connecting rod 31 extends into the inner cavity 25 and movably passes through the side wall of the protrusion 23. The other end of the second connecting rod 31 is movably connected to the first connecting rod 28. When the wall panel body 6 is installed, the pressure block 24 gradually approaches the protrusion 23 through the wall panel positioning structure 9. The pressure block 24 drives the guide post 26 to retract inward, and the first connecting rod 28, which is movable between the fixing block 27 and the guide post 26, opens, thereby pushing the second connecting rod 31 to extend outward. This causes the arc-shaped positioning piece 30 in the placement groove 29 to fit against the side wall of the inner groove 10, ensuring that the wall panel body 6 will not shift after installation and guaranteeing the accurate installation position of each wall panel body 6.

[0035] In practical applications, firstly, the mounting keel 1 is connected and fixed to the wall surface to be decorated. Then, the elastic alloy fastener 3, consisting of a flat plate 4 and a zigzag side plate 5, is installed in the U-shaped bracket 2 on the mounting keel 1, thus completing the installation of the elastic alloy fastener 3 and the mounting keel 1.

[0036] Next, the wall panel body 6 with the snap-fit ​​groove 7 is pressed from the front into the space between two adjacent mounting keels 1, so that it is limited by the wing plates on both sides of the mounting keel 1 and the lateral extrusion force of the folded side plate 5 in the elastic alloy fastener 3, so that the wall panel body 6 is leveled and fixed between the mounting keels 1, thereby completing the wall panel installation. Then, the wall panel body 6 is installed one by one according to the subsequent method.

[0037] Through the fastener positioning structure 8, when the wall panel body 6 is pressed from the front, the outer side of the zigzag side plate 5 will contact the arc-shaped elastic metal sheet 14 on the positioning plate 12. The side plate locking groove 13 adapts to the deformation of the zigzag side plate 5. At this time, the positioning plate 12 is subjected to lateral pressure, which will cause the connecting column 20 to contract, so that the movable rod 16 opens at a certain angle under the cooperation of the guide wheel 17 and the rolling groove 18. At the same time, the positioning spring 22 provides a certain reaction force, thereby playing an auxiliary positioning effect on the side of the wall panel body 6. When the wall panel body 6 is installed, the wall panel positioning structure 9 causes the pressure block 24 to gradually approach the protrusion 23. The pressure block 24 drives the guide column 26 to contract inward, and the fixing block 27 and the guide column 23 are connected. The movable connecting rod 28 opens, thereby pushing the connecting rod 31 outward, so that the arc-shaped positioning piece 30 in the placement groove 29 fits against the side wall of the inner groove 10, so that the wall panel body 6 will not shift after installation, ensuring the accurate installation position of each wall panel body 6. When it is necessary to disassemble, repair or replace any wall panel body 6, simply use a suction cup to hold the wall panel body 6, and apply an outward pulling force greater than the compressive force on both sides to move the wall panel body 6 outward, thereby disassembling the wall panel body 6. Use a suction cup to fix the replaced wall panel body 6, and apply an inward force greater than the compressive force on both sides to move the wall panel body 6 inward until it moves to the rear wing edge of the keel and is stuck, thereby completing the replacement installation.

[0038] The device of this application utilizes elastic alloy fasteners 3 in conjunction with a wall panel body 6 having snap-fit ​​grooves 7. This allows the wall panel body 6 to be snapped into the elastic alloy fasteners 3 from the front while the elastic alloy fasteners 3 are being installed with the mounting keel 1. This results in a simpler structure and easier processing. The wall panel body 6 with snap-fit ​​grooves 7, when used with a specific keel system, can achieve front-side disassembly and single-panel disassembly, making the installation method more flexible and the installation logic simpler, thus improving installation efficiency.

[0039] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
