Description

Technical Field

[0001] The present invention relates to the technical field of decoration, and particularly to a concealed internal corner type wall panel and ceiling installation component and an installation method thereof. Background Art

[0002] A ceiling refers to a kind of decoration for the top decoration of a housing living environment. Simply speaking, it refers to the decoration of the ceiling and is one of the important parts of interior decoration.

[0003] The ceiling has the functions of heat preservation, heat insulation, sound insulation, and sound absorption, and is also a concealed layer for projects such as electrical, ventilation and air conditioning, communication, fire prevention, and alarm pipeline equipment.

[0004] Home decoration ceiling is a common link in home decoration. According to different materials of decorative panels, the classification is also different. The ceiling decoration materials are the main basis for distinguishing the ceiling names, mainly including: light steel keel gypsum board ceiling, gypsum board ceiling, mineral wool board ceiling, plywood ceiling, special-shaped long aluminum gusset ceiling, square painted aluminum gusset ceiling, painted glass ceiling, aluminum honeycomb perforated sound-absorbing board ceiling, whole-house duplex ceiling, etc. It occupies a quite important position in the entire room decoration. Appropriate decoration of the room top surface can not only beautify the indoor environment, but also create a rich and colorful indoor space art image. When selecting ceiling decoration materials and design schemes, the principles of saving materials, firmness, safety, beauty, and practicality should be followed.

[0005] During interior decoration, the ceiling is always decorated. A good and reasonable ceiling design can make up for the deficiencies such as being too high and too wide in the original building structure, and also has effects such as dividing space, enhancing the interior decoration effect, and heat insulation and heat preservation.

Detailed implementation mode

[0038] To make the purpose, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be described below through specific embodiments shown in the drawings. However, it should be understood that these descriptions are only exemplary and do not intend to limit the scope of the present invention. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present invention.

[0039] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention.

[0040] The following will describe the embodiments of the present invention in detail with reference to the drawings.

[0041] Embodiment 1: In the prior art, there will be gaps between the ceiling panel and the wall decorative panel. These gaps will affect the aesthetics and unity of the overall space, affect the user experience, and are not conducive to the promotion and application of the ceiling in the market. Moreover, during actual use, since the bathroom is a relatively enclosed independent space, isolated from other indoor spaces, the air circulation is restricted, and it is difficult to directly mix with the external air. Usually, it only has an exhaust fan and no dedicated fresh air inlet. When the exhaust fan discharges some air in the bathroom and there is no corresponding fresh air inflow, the pressure inside the bathroom will decrease, which is the so-called negative pressure in the bathroom. When opening the door when the negative pressure in the bathroom occurs, it will cause the ceiling to fluctuate vertically. In the prior art, the connection methods between the ceiling panel and the wall decorative panel are mainly the following: 1. Gluing, using special construction tapes or construction adhesives for bonding connection; 2. Wiring or nailing, that is, using wiring or special ceiling nails to pass through the ceiling board and fix it on the wall. Over time, both of the above methods will cause the separation between the ceiling and the wall, posing a great potential safety hazard and affecting the user experience.

[0042] To solve the above technical problems, as Figure 1 shown, a hidden corner type wall panel and ceiling installation component in this embodiment mainly consists of a ceiling panel 1, a ceiling edge trim 2, a wall-ceiling connection member 3, a wall decorative panel 4, and a corner hidden member 9. Specifically, as Figure 2 shown, it is also necessary to process the ceiling panel 1 to make it fit the ceiling edge trim 2, and a panel embedding groove 1-1 is opened on the side of the above ceiling panel 1.

[0043] As Figure 3 shown, the ceiling edge trim 2 in this embodiment has an edge trim embedding part 2-1, an edge trim fixing part 2-2, and an edge trim connecting part 2-3. The above edge trim connecting part 2-3 connects the above edge trim fixing part 2-2. To ensure the structural strength at the connection between the above edge trim connecting part 2-3 and the above edge trim fixing part 2-2 and avoid stress concentration at the connection, the above edge trim fixing part 2-2 and the above edge trim connecting part 2-3 are vertically arranged in this embodiment. The above edge trim embedding part 2-1 is formed on the side of the above edge trim connecting part 2-3. Similarly, to ensure the structural strength at the connection between the above edge trim embedding part 2-1 and the above edge trim connecting part 2-3 and avoid stress concentration at the connection, the above edge trim embedding part 2-1 and the above edge trim connecting part 2-3 are vertically arranged in this embodiment. By embedding the above edge trim embedding part 2-1 into the above panel embedding groove 1-1, the connection between the ceiling panel 1 and the ceiling edge trim 2 is realized, which is simple, convenient, and easy to operate, can greatly shorten the installation working hours, and reduce the installation and use costs.

[0044] As Figure 4 And Figure 5As shown, the wall-top connector 3 in this embodiment includes a first positioning portion 3-1, a second positioning portion 3-2, and a connecting portion 3-5. The connecting portion 3-5 connects the first positioning portion 3-1 and the second positioning portion 3-2 and extends towards the side of the second positioning portion 3-2 to form a supporting portion 3-6 for supporting the ceiling panel 1. The second positioning portion 3-2 is arranged below the connecting portion 3-5 and forms an installation groove 3-3 with the first positioning portion 3-1 for installing the wall decorative panel 4. By extending the connecting portion 3-5 towards the side of the second positioning portion 3-2 to form the supporting portion 3-6 for supporting the ceiling panel 1, the ceiling panel 1 is supported, and then an installation groove 3-3 for inserting the top of the wall decorative panel 4 is formed between the second positioning portion 3-2 and the first positioning portion 3-1. During the specific installation process, fixing glue 6 is applied in the installation groove 3-3 to realize the connection between the wall-top connector 3 and the wall decorative panel 4.

[0045] To hide the gap that may exist between the ceiling panel 1 and the wall decorative panel 4, the internal corner hiding member 9 is installed at the corner of the ceiling panel 1 and the wall decorative panel 4. Specifically, the wall-top connector 3 further has a hanging hook 3-11, and the internal corner hiding member 9 has a hanging groove 9-9. The hanging hook 3-11 is used to be hung in the hanging groove 9-9 to realize the installation of the internal corner hiding member 9, ensuring the installation rate and installation effect.

[0046] As Figure 7 and Figure 8 As shown, the internal corner hiding member 9 in this embodiment includes a ceiling panel fitting portion 9-1 and a wall panel fitting portion 9-2. The upper surface of the ceiling panel fitting portion 9-1 is arranged to fit with the lower surface of the ceiling panel 1, and it can be fixedly bonded by using fixing glue at the fitting position. The outer surface of the wall panel fitting portion 9-2 is arranged to fit with the outer surface of the wall decorative panel 4. Similarly, it can be fixedly bonded by using fixing glue at the fitting position. To make the ceiling panel fitting portion 9-1 and the wall panel fitting portion 9-2 form an integral structural member, a first hiding member connecting portion 9-3 and a second hiding member connecting portion 9-4 are connected between the ceiling panel fitting portion 9-1 and the wall panel fitting portion 9-2. A decorative strip 9-5 is connected between the first hiding member connecting portion 9-3 and the second hiding member connecting portion 9-4. The decorative strip 9-5 plays a decorative role while enhancing the overall structural strength of the internal corner hiding member 9. The cross-section of the decorative strip 9-5 in this embodiment is linearly arranged, which is convenient for taking. The cross-section of the decorative strip 9-5 can also be arc-shaped, which can improve the overall aesthetic degree of the internal corner hiding member 9 and prevent injury to the operator during the installation process; or the cross-section of the decorative strip 9-5 is right-angled, that is, one side of the decorative strip 9-5 is on the same straight line as the first hiding member connecting portion 9-3, and the other side is on the same straight line as the second hiding member connecting portion 9-4, and the whole internal corner hiding member 9 is square-shaped, reducing the manufacturing difficulty.

[0047] To enhance the overall structural strength of the internal corner concealment member 9 and prevent the probability of deformation of the above-mentioned decorative strip 9-5 caused by external forces, a first reinforcing rib 9-7 is connected between the first concealment member connection part 9-3 and the second concealment member connection part 9-4 located inside the above-mentioned decorative strip 9-5. In this embodiment, a third reinforcing rib 9-8 is provided on the side of the wall panel fitting part 9-2 to ensure the structural strength at the wall panel fitting part 9-2 and reduce the probability of deformation of the wall panel fitting part 9-2, thereby ensuring its degree of fit with the surface of the wall decorative panel 4. Similarly, the wall panel fitting part 9-2 is perpendicularly arranged with the third reinforcing rib 9-8 to reduce the probability of fracture at the connection between the wall panel fitting part 9-2 and the third reinforcing rib 9-8. The above-mentioned hanging grooves 9-9 are two. One of the above-mentioned hanging grooves 9-9 is formed between the second reinforcing rib 9-6, the first concealment member connection part 9-3 and the top plate fitting part 9-1, and the other above-mentioned hanging groove 9-9 is formed between the second concealment member connection part 9-4, the wall panel fitting part 9-2 and the third reinforcing rib 9-8.

[0048] To be adapted to the above two hanging grooves 9-9, a masking strip 3-10 is formed between the above-mentioned supporting part 3-6 and the second positioning part 3-2. Correspondingly, two of the above-mentioned hanging hooks 3-11 are formed at the end of the masking strip 3-10. The size of the above-mentioned hanging hook 3-11 is adapted to the above-mentioned hanging groove 9-9 to ensure the installation effect of the above-mentioned internal corner concealment member 9.

[0049] The specific connection method between the above-mentioned ceiling-wall connecting member 3 and the ceiling edge trim member 2 is that a trim member insertion block 2-6 is further provided below the trim member fixing part 2-2 of the above-mentioned edge trim member. A trim member slot 2-5 is formed between the trim member insertion block 2-6 and the trim member connection part 2-3 of the above-mentioned edge trim member. For the above-mentioned ceiling-wall connecting member 3, a connecting member insertion block 3-8 is provided above the above-mentioned connection part 3-5. A connecting member slot 3-9 is formed between the connecting member insertion block 3-8 and the first positioning part 3-1. By inserting the above-mentioned trim member insertion block 2-6 into the above-mentioned connecting member slot 3-9 and inserting the above-mentioned connecting member insertion block 3-8 into the above-mentioned trim member slot 2-5, the connection between the above-mentioned ceiling-wall connecting member 3 and the above-mentioned ceiling edge trim member 2 is realized. A clearance fit can be provided between the two to adapt to the negative pressure in the bathroom and reduce the probability of detachment between the ceiling panel 1 and the wall decorative panel 4, ensuring safety during use.

[0050] To ensure the stability at the connection between the panel groove 1-1 and the trim member embedding part 2-1 and reduce the probability of detachment at the connection, the trim member embedding part 2-1 is adapted to the panel groove 1-1 and is arranged in a "T" shape. In this embodiment, a clearance fit is provided between the trim member embedding part 2-1 and the panel groove 1-1, that is, the volume of the trim member embedding part 2-1 is slightly smaller than the volume of the panel groove 1-1, so that the ceiling edge trim member 2 or the ceiling panel 1 has a certain margin of movement to reduce the impact of the negative pressure in the bathroom on the ceiling panel.

[0051] In order to further ensure the stability of the ceiling trimming piece 2 during the installation process, the ceiling panel 1 located above the panel groove 1-1 is cut to form a panel positioning portion 1-2, and the trimming piece fixing portion 2-2 is fixed to the panel positioning portion 1-2 by a fixing member 8. The fixing member 8 is a fastening screw with a simple structure and high economical practicality. In order to ensure the stability of the connection between the ceiling trimming piece 2 and the ceiling panel 1, the ceiling panel 1 located below the panel groove 1-1 is cut to form a panel positioning portion 2-3, and the bottom of the trimming piece connecting portion 2-3 is formed with a trimming piece abutting portion 2-4, which is used to abut with the panel positioning portion 2-3, or to be arranged in a close fit. It can also be said that the trimming piece abutting portion 2-4 limits the upward movement of the ceiling trimming piece 2 and limits the drooping of the ceiling panel 1. In order to ensure the structural strength of the connection between the edge trimming member abutting portion 2-4 and the edge trimming member connecting portion 2-3 and avoid stress concentration at the connection, the edge trimming member abutting portion 2-4 and the edge trimming member connecting portion 2-3 are vertically arranged.

[0052] In this embodiment, the plug-in portion 3-4 is formed in the installation groove 3-3. Figure 6 As shown, a plug-in slot 4-1 adapted to the plug-in portion 3-4 is opened on the top of the wall decorative panel 4. By plugging the plug-in portion 3-4 into the plug-in slot 4-1, the contact area between the wall top connector 3 and the wall decorative panel 4 is increased, thereby ensuring the stability of the connection between the wall top connector 3 and the wall decorative panel 4.

[0053] The cross-sectional height of the panel positioning part 2 1-3 is matched with the thickness of the support part 3-6 in the wall-top connector 3, and the support part 3-6 is abutted in the panel positioning part 2 1-3. By forming the panel positioning part 2 1-3 matched with the support part 3-6 at the bottom of the ceiling panel 1, it is possible to prevent the support part 3-6 from protruding from the surface of the ceiling panel 1 to ensure the overall aesthetics of the ceiling. Alternatively, an abutting part 3-7 is formed on the side of the support part 3-6, and the contact area between the abutting part 3-7 and the ceiling panel 1 is greater than the contact area between the support part 3-6 and the ceiling panel 1, so as to ensure the stability of the contact between the wall-top connector 3 and the ceiling panel 1.

[0054] In order to be able to quickly assemble the above-mentioned wall top connector 3 to the top of the wall decoration panel 4, the length of the above-mentioned plug-in portion 3-4 in this embodiment is shorter than the length of the above-mentioned positioning portion 2 3-2, and the wall decoration panel 4 can be quickly moved into the installation groove 3-3, and then the plug-in portion 3-4 can be plugged into the plug-in groove 4-1.

[0055] In order to increase the contact area between the above-mentioned wall top connector 3 and the original wall 5, in this embodiment, the length of the first positioning portion 3-1 is greater than the length of the second positioning portion 3-2. The connecting portion 3-5 and the first positioning portion 3-1 are arranged in an inverted T shape. The first positioning portion 3-1 and the original wall 5 can be fitted or arranged in parallel.

[0056] Since the surface of the wall decorative panel 4 is usually a regular plane, in order to achieve rapid assembly, in this embodiment, the first positioning portion 3-1 and the second positioning portion 3-2 are arranged in parallel, that is, the formed installation groove 3-3 is adapted to the top of the wall decorative panel 4. The installation groove 3-3 can be rectangular, circular or any other shape, as long as it is adapted to the top of the wall decorative panel 4, and is not limited herein.

[0057] After the wall decorative panel 4 and the wall top connector 3 are assembled, the distance between the wall decorative panel 4 and the original wall 5 is adjusted by the rear panel adjusting feet 7. The specific distance is specified according to project requirements, and the rear panel adjusting feet 7 are made according to needs. The shape and size of the rear panel adjusting feet 7 are not specifically limited.

[0058] In this embodiment, the above-mentioned ceiling edge trim 2, the above-mentioned wall top connector 3 and the internal corner hidden part 9 are all prefabricated parts. The prefabricated parts can be mass-produced to achieve economies of scale, greatly reducing costs. Through standardized production, design, procurement and production can be optimized, waste can be reduced, and costs can be lowered. The prefabricated parts usually complete most of the processing in the factory. Only simple connection and debugging are required for on-site installation, and no complex installation is needed, which can significantly shorten the construction period. The prefabricated parts can be produced mechanized to ensure high quality. At the same time, the factory can establish a perfect quality management system, which is convenient for quality control to ensure the service life of the wall top connector 3, the ceiling edge trim 2 and the internal corner hidden part 9 and reduce the use cost.
