Description

Technical Field

[0001] This utility model relates to the field of decorative profiles technology, and in particular to ceiling edge sealing profiles. Background Technology

[0002] In the existing field of interior decoration technology, corner profiles are often used to assist in making the corners of suspended ceilings more aesthetically pleasing and straighter, thus simplifying the processing and enhancing the overall appearance. For example, existing technology CN216713706U utilizes corner profiles to achieve this purpose.

[0003] However, in actual use, certain drawbacks have been discovered, especially during ceiling decoration. The profile needs to be attached to the plasterboard first, as the installation length is typically quite long (generally over 3 meters). Under gravity, it's difficult to initially secure the heavy profile to the plasterboard. Multiple people need to work together, using other tools, to fix the profile to the plasterboard before proceeding with subsequent work (installing screws and adhesives). Otherwise, quality defects may occur, resulting in displacement or misalignment. Continuing construction with these defects will lead to deviations in all subsequent processes, such as applying plaster and putty layers.

[0004] To solve the above problems, a new technical solution is needed that can achieve stable and quick installation of profiles and reduce construction difficulty. Utility Model Content

[0005] The purpose of this utility model is to solve the above-mentioned defects and provide a ceiling edge sealing profile that, through its special structure, simplifies and facilitates subsequent construction, reduces the difficulty of construction for personnel, and makes the processing smoother, thereby solving one of the problems existing in the background technology.

[0006] The objective of this utility model is achieved through the following means:

[0007] A ceiling edge sealing profile includes two perpendicular straight edges, one of which is a horizontal edge for bonding with the bottom surface of the gypsum board and the other is a vertical edge for bonding with the side surface of the gypsum board. A finishing edge extends downward along the vertical edge. A reverse hanging part is provided at the upper end of the vertical edge, and a groove is formed between the reverse hanging part and the horizontal edge for locking along the thickness direction of the gypsum board.

[0008] Furthermore, the reverse suspension portion includes a locking edge extending in the same direction as the horizontal edge, and an extension portion perpendicular to the locking edge.

[0009] Furthermore, the extension is perpendicular to the end of the engaging edge.

[0010] Furthermore, the extension section has an extension groove on the side facing the gypsum board.

[0011] Furthermore, a connecting groove is provided on the outer side of the vertical edge for connecting multiple profiles to each other.

[0012] Furthermore, several adhesive protrusions are provided on the outer side of the sealing edge.

[0013] Furthermore, the lower end of the rim has a pointed corner structure.

[0014] Furthermore, a recessed receiving angle is provided at the intersection of the vertical and horizontal sides.

[0015] The beneficial effects of this invention are as follows: by providing a reverse hanging part at the upper end of the vertical edge, the plasterboard is secured using this reverse hanging part, making it easier for construction workers to operate and ensuring the aesthetics of the corners of the suspended ceiling. This makes construction more convenient, faster, and smoother. Attached Figure Description

Detailed Implementation

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0025] To facilitate understanding, the present invention will now be described in further detail with reference to specific implementation examples, but this is not intended to limit the present invention.

[0026] Example 1 (Reference) Figure 1-4 The profile is made of aluminum alloy and is formed by extrusion. It has a strip-shaped structure and its length can be cut according to the needs of the site.

[0027] The profile includes two perpendicularly intersecting straight edges 1, each edge 1 divided into two sides: a vertical edge 102 and a horizontal edge 103. The horizontal edge 103 is flush with the lower surface of the gypsum board 10, and the vertical edge 102 is flush with the side edge of the gypsum board 10. The surface where the vertical edge 102 contacts the gypsum board 10 is provided with corrugated teeth 101. These corrugated teeth 101 are mainly used to increase the contact area with the adhesive (such as putty powder), thereby increasing the adhesion (see reference). Figure 4 ).

[0028] like Figure 1 , 2 As shown in Figure 4, a closing edge 2 extends downwards along the vertical edge 102, forming a sharp corner at the bottom of the closing edge 2 as a leveling end (i.e., when applying the joint compound 12 and putty layer 11, this sharp corner serves as a reference point to facilitate smooth and aligned construction). To ensure a stronger bond between the joint compound 12 and putty layer 11, several adhesive protrusions 5 are provided on the outer side of the closing edge 2. During the initial application of the mud-like joint compound 12, it will penetrate into the inner side of the adhesive protrusions 5. After the joint compound 12 solidifies, it forms a relatively stable tensile structure. On one side of the horizontal edge 103, an adhesive edge 4 is provided vertically. Its purpose is to facilitate the alignment of the plasterboard 10 when it is placed below the horizontal edge 103. The joint compound 12 is filled through the gap between the adhesive edge 4 and the closing edge 2 to facilitate the bonding of the plasterboard 10.

[0029] In practical applications, most ceiling enclosure profiles use the existing technology CN216713706U. The gypsum board 10 and the wall 9 (or keel frame, etc.) are first fixed. The construction process involves applying joint compound 12 or other similar adhesive to the lower surface and sides of the gypsum board 10, and then initially fixing the profile at its external corners. However, because the profile is long and heavy, multiple people are needed to assist in the initial bonding, alignment, and compression of the profile. It is then fixed with screws or supports to allow for subsequent operations. This process is relatively complex and wasteful of labor costs.

[0030] refer to Figure 1 , 23. In this technical solution, a reverse suspension part 3 is provided above the vertical edge 102. A groove-like structure is formed by the engaging edge 302 on the reverse suspension part 3 and the horizontal edge 103. This groove-like structure is used to engage the gypsum board 10, initially fixing the profile to the gypsum board 10 along its thickness direction. This allows a single person to initially fix the long strip profile to the gypsum board 10. After the initial connection, screws or other connecting components can be used to finally fix the profile to the gypsum board 10. This technical structure can conveniently solve the problems in the prior art.

[0031] Additionally, at the end of the engaging edge 302, a portion 301 is provided perpendicular to the engaging edge 302. This portion 301 can be used to reflect the light emitted by the ambient light 13 (or light tube) installed above the plasterboard 10, thereby enhancing the lighting effect. It can also be used to bond the plasterboard 10 to the plasterboard 10 in emergency situations (e.g., when the thickness of the plasterboard 10 exceeds the design thickness of the groove structure), achieving the same purpose of emergency bonding (same as existing technical solutions). Furthermore, an expansion groove 303 is provided on the expansion portion 301, which can be used to install light strips to achieve the same effect as the ambient light 13 on the suspended ceiling.

[0032] refer to Figure 7 Because the ceiling lengths vary in different rooms, a connecting groove 6 is provided on the side of the vertical edge 102 away from the plasterboard 10 to accommodate different ceiling sizes. A strip-shaped connecting piece 7 is inserted into the connecting groove 6 to connect multiple profiles. This design is suitable for splicing ceilings of different lengths.

[0033] refer to Figure 3 The corners of the gypsum board 10 are external corners, and the intersection of the vertical edge 102 and the horizontal edge 103 of the profile is an internal corner. In order to make the profile and the gypsum board 10 fit more tightly, a concave receiving angle 8 is provided at the intersection of the vertical edge 102 and the horizontal edge 103. This allows the corners of the gypsum board 10 to be inserted into the receiving angle 8, thereby achieving a tighter fit between the profile and the gypsum board 10.

[0034] Figure 5 This is a cross-sectional schematic diagram of Embodiment 2 of this design scheme. The difference between Embodiment 2 and Embodiment 1 lies in the structural design of the reverse suspension part 3.

[0035] refer to Figure 6 The difference between Embodiment 3 and Embodiment 1 is that the design of the extension part 301 and the extension slot 303 is eliminated. Under the premise of achieving basic functions, the design of the reverse suspension part 3 is further simplified.

[0036] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
