Description

Technical Field

[0001] The utility model relates to the technical field of decoration and decorative profiles, in particular to a profile for forming shadow seams. Background Art

[0002] In the existing field of interior decoration and decoration technology, shadow seams are set around the top of the wall to increase the layering of the interior ceiling. Light strips can also be added at the shadow seams to achieve a more beautiful effect.

[0003] In practice, the construction of this type of shadow seam is extremely difficult due to the upwardly concave structure. This makes it nearly impossible to smooth the sides, leaving insufficient space for applying putty powder and installing other accessories. To address this issue, existing technologies have designed separate profiles, such as those in CN211200893U and CN208415662U. However, both designs simply adhere to the gypsum board, utilizing the L-shaped curved edges of the profile to achieve the concave structure. Because the profile surface is already smooth and flat, there's no need to apply putty powder to the sides. However, both solutions suffer from the drawbacks of difficult fixing and machining. Because the shadow seam is typically designed on the ceiling, adhesive materials like gypsum and putty powder cannot properly secure the profile until they have solidified. This can lead to unstable fixing, profile deviation, and the need for constant force to maintain the profile during the renovation process, causing inconvenience for construction workers. Furthermore, these existing structures are not easy to install light strips.

[0004] In order to solve one of the above problems, a new technical solution is needed to achieve stable and fast installation of profiles, reduce construction difficulty and improve efficiency. Utility Model Content

[0005] The purpose of the present invention is to solve the above defects and provide a profile for forming a shadow seam, which can quickly stabilize the profile and the ceiling through the reinforcement technical solution of the profile, thereby solving one of the problems existing in the background technology.

[0006] The purpose of this utility model is achieved by the following methods:

[0007] A profile for forming a shadow seam, comprising a sheet-like horizontal plate for forming the shadow seam, a closing plate being provided in a vertical direction of the horizontal plate, a support plate being provided in a direction perpendicular to the closing plate and away from the horizontal plate, the support plate being connected to the closing plate and used to form support with a covering keel, a downwardly opening directional groove being provided on the support plate, the directional groove being perpendicular to the support plate and used to stabilize the direction of a screw, a barrier portion being provided on the outer side of the directional groove and away from the closing plate and used to separate and align the gypsum board.

[0008] Furthermore, the inner side surfaces on the opposite sides of the orientation groove are provided with a wavy stripe structure.

[0009] Furthermore, the orientation slot is composed of two straight sides that are parallel to each other and perpendicular to the support plate.

[0010] Furthermore, a downward extending adhesive edge is provided at the outer end of the support plate, the barrier portion is connected to the adhesive edge and the barrier portion is arranged on the outer side of the adhesive edge, and the top plane of the support plate is lower than the top plane of the cross plate, and a hook is provided on the side of the adhesive edge facing the barrier portion, and the hook faces upward.

[0011] Furthermore, the top end of the barrier portion is flush with the support plate, and the side of the barrier portion facing the gypsum board is parallel to the edge of the gypsum board.

[0012] Furthermore, the height from the lower end of the bonding edge to the support portion is smaller than the height from the lower end of the closing plate to the support portion, forming an inclined structure as a whole.

[0013] Furthermore, repair grooves are provided on the left and right sides of the lower end of the directional groove. The two repair grooves are concave structures. The openings of the two repair grooves are opposite to each other and tilted downward, forming an eight-shaped structure.

[0014] Furthermore, the edges of the two seam-filling grooves are respectively connected to the closing plate and the bonding edge to form an eight-shaped structure.

[0015] Furthermore, the lower edges of the openings of the two repairing grooves extend in opposite directions to form a barb structure.

[0016] Furthermore, a concave light groove is provided at one end of the closing plate close to the horizontal plate for accommodating the strip light strip.

[0017] The beneficial effects of the present invention are as follows: by providing the directional grooves on the profile, it is easier for construction workers to pre-fix the profile, thereby facilitating subsequent construction steps. In addition, the fixing position of the screws is changed, thereby solving the problem of gluing multiple layers of gypsum boards, making the ceiling decoration method of multiple layers of gypsum boards more convenient, faster and smoother.

DETAILED DESCRIPTION

[0025] The present invention will be described in further detail below with reference to the accompanying drawings and specific implementations.

[0026] For ease of understanding, the present invention will be described in further detail with reference to specific implementation cases, but this is not intended to limit the present invention.

[0027] Example 1 (reference Figure 1 ,4), The material of the profile is aluminum alloy, formed by an extrusion mechanism, and the overall structure is a strip.

[0028] The profile includes a horizontally arranged sheet-like horizontal plate 1, one end of which is aligned with the wall, and a vertically arranged closing plate 2 at the other end. The closing plate 2 and the horizontal plate 1 form an L-shaped structure. When combined with the wall, a concave shadow seam structure is formed. A support plate 3 is vertically arranged in the middle of the closing plate 2, and the support plate 3 is located away from the horizontal plate 1. The support plate 3 is used to connect with the covering keel 13 and is fixed with screws. During decoration construction, the profile is fixed to the covering keel 13 to facilitate subsequent construction procedures. Because the decoration location is on the ceiling, the fixing direction is from bottom to top, which makes the work of the construction workers very inconvenient. According to feedback from actual construction workers, screws often go off-center or become loose. In order to solve the above problem, a U-shaped orientation groove 4 is provided on the support plate 3. The orientation groove 4 is formed by two aluminum sheets arranged opposite to each other, and a V-shaped screw groove 301 is provided on the support plate 3 facing downward and the screw groove 301 is provided in the middle position of the orientation groove 4. When screwing, manually insert the screw into the directional slot 4, with the pointed end of the screw inserted into the screw slot 301. This secures the screw in place in all three directions, upward, left, and right, similar to being held by hand, ensuring a stable and secure position. The screw can then be driven upward using a screwdriver. This significantly improves construction speed and reliability, and the screw driving direction is stable and prevents deviation. Furthermore, a barrier 6 is provided on the outside of the directional slot 4, away from the closing plate 2. This barrier 6 serves to separate and align the gypsum boards, providing better positioning and alignment, and enhancing the aesthetics of the ceiling finish. Conventional screw driving is typically located outside the barrier 6 (e.g., in the prior art patent CN209413228U). This structural design has two drawbacks: one is that the support plate 3 is positioned between the two gypsum boards, resulting in unevenness. To address this issue, one of the gypsum boards must be reworked to ensure a seamless and flush fit between the two gypsum boards. The second problem is that even when the gypsum boards are flush after processing, the screw nuts will still protrude when the screws are driven in, affecting the smoothness between the two gypsum boards. This situation requires tedious work for on-site construction workers. However, in this design, the directional grooves 4 for the screw driving points are located inside the barrier 6, completely eliminating the unevenness between the multiple layers of gypsum boards and facilitating subsequent construction.

[0029] Wave-shaped stripes are provided on the opposite inner sides of the directional groove 4. The advantage of these stripes is that they further secure the screws and prevent them from loosening. Later in the construction process, caulking plaster 16 (gel-like slurry) is applied to the directional groove 4. The caulking plaster 16 will seep into the wavy stripes, increasing the bonding area while also forming a bond with the screw through the gaps in the stripes, effectively holding the screw in place. Once the caulking plaster 16 dries, the screw becomes even more secure.

[0030] In this embodiment, the orientation slot 4 is a U-shaped structure, with two straight sides parallel to each other and perpendicular to the support plate 3, forming a stable guide structure to prevent the screw from deflecting.

[0031] A downward-extending adhesive edge 7 is provided at the outer end of the support plate 3. A barrier 6 is positioned in the middle of the adhesive edge 7, near the support plate 3. The adhesive edge 7 and barrier 6 are connected and positioned outside the adhesive edge 7. The barrier 6 is used to align the second gypsum board 15. Wave-shaped stripes are formed on the outer surface of the barrier 6 near the second gypsum board 15, providing a larger contact area between the caulking plaster 16 and the second gypsum board 15, thereby achieving better adhesion. During construction, simply pushing the second gypsum board 15 toward the barrier 6 creates an alignment effect, and because the profile is firmly fixed, there is no deviation. The space formed between the adhesive edge 7 and the barrier 6 also provides a larger bonding area, further improving adhesion.

[0032] In order to ensure that the gypsum board is more stable after the gypsum is cured, a hook is provided on the side of the adhesive edge 7 facing the barrier portion 6, and the hook is facing upward. In this way, when the caulking gypsum 16 is cured, a reverse hook force is formed to prevent the gypsum board and other materials from loosening under the action of gravity.

[0033] The top of the barrier 6 is flush with the support plate 3, and the side of the barrier 6 facing the gypsum board is parallel to the edge of the gypsum board, thereby achieving more convenient installation and making alignment and leveling more convenient.

[0034] To facilitate the application of caulking plaster 16 to the profile and achieve a good bonding effect, the height from the lower end of the adhesive edge 7 to the support portion 3 is less than the height from the lower end of the closing plate 2 to the support portion, thereby forming an overall inclined structure from one side of the barrier portion 6 to the shadow seam. This facilitates the application of caulking plaster 16 after the second gypsum board 15 is attached, and also facilitates the leveling of the entire ceiling.

[0035] In order to further ensure that the caulking plaster 16 can fully enter the directional groove 4 when applied, and to avoid the bond between the cured caulking plaster 16 and the profile from changing in quality (i.e., the bond effect disappears) due to thermal expansion and contraction (or aging) over a long period of time, the caulking plaster 16 will not separate from the profile even if the bond function is lost. The following design is adopted, that is, a filling groove 5 is provided on the left and right sides of the lower end of the directional groove 4, respectively. The two filling grooves 5 are respectively concave structures, and the openings 501 of the two filling grooves 5 are opposite to each other, and the openings 501 of the filling grooves 5 are inclined downward, so that the two filling grooves 5 are in an eight-shaped structure, and the openings 501 form a barb structure. In this way, even if the solidified caulking plaster 16 and the profile are loose, because a part of the solidified caulking plaster 16 enters the filling groove 5 and the opening 501 forms a barb shape, even if it is loose, it will be hooked by the filling groove 5 of the profile and will not be completely loosened. Moreover, the profile is installed in a long strip structure. For example, the solidified caulking plaster 16 on a profile of about 5 meters can also form sufficient pulling force so that it cannot be completely detached, further ensuring quality and safety. At the same time, the edges of the two filling grooves are connected to the closing plate and the bonding edge respectively to form an eight-shaped structure. Such a structure makes it easier for the caulking plaster 16 to fully enter the filling groove 5. Because the lower end opening is large, when the caulking plaster 16 is applied, when the external force squeezes the caulking plaster 16, the caulking plaster 16 is squeezed into the small space, making it easier to enter the directional groove 4 and the filling groove 5.

[0036] In order to further maintain stability, a dovetail tooth 101 is provided on the surface of the horizontal plate 1, close to the ceiling, so that adhesives such as gypsum can enter the dovetail tooth 101 during bonding, forming a barb structure, making the profile bonded more firmly.

[0037] Example 2 (reference Figure 5 ), on the basis of the technology of Example 1, a concave lamp trough 9 is provided at one end of the closing plate 2 close to the horizontal plate 1, and a strip light strip can be installed inside the lamp trough 9. A lampshade 10 is provided at the opening of the lamp trough 9 to protect the lamp trough 9 and prevent the entry of dust. At the same time, it is convenient for later maintenance and care, because the lampshade 10 is covered to form a flat surface, which can be wiped with a rag.

[0038] The following further describes the construction and installation methods of the profile to further understand the structural design and its use (refer to Figure 2 、 3 , 6).

[0039] First, nail the load-bearing keel 12 to the ceiling 11 and secure the cladding keel 13 beneath it, forming the installation foundation. Next, install the profile at the edge where the cladding keel 13 meets the wall 18. Apply a coating with adhesive properties, such as plaster or latex paint, to the cladding keel 13 before installation. Then, glue the crossbar 1 there to provide a preliminary fixation. Next, insert the first gypsum board 14 into the gap between the support plate 3 and the cladding keel 13. Then, drive screws through the directional slots 4 to securely connect the profile, first gypsum board 14, and cladding keel 13.

[0040] Then attach the second gypsum board 15 to the lower surface of the first gypsum board 14, apply caulking plaster 16 to the position of the baffle board 6 and the bonding edge 7, and move one end of the second gypsum board 15 close to and align with the baffle board 6 so that the caulking plaster 16 bonds the two together. At the same time, the second gypsum board 15 and the first gypsum board 14 can be fixed with glue or screws.

[0041] Further, fill the caulking plaster 16 at the position of the repairing groove 5 to make the profile in a more stable state, and continue to apply putty 17 to make the entire surface smoother and flatter. Apply putty 17 to the position of the closing plate 2 to achieve the purpose of smoothing the closing.

[0042] If it is a profile with a lamp trough 9, a strip light strip is installed in the lamp trough 9 in advance. The light strip can be attached to the lamp trough 9 with adhesive, leaving the end outside for subsequent power supply, and then covered with a lampshade 10. The subsequent construction and installation steps are the same as the above steps.

[0043] In this technical solution, the installation method of double-layer gypsum board is introduced. If the fixed installation of single-layer gypsum board is to be fixed, the top planes of the horizontal board 1, the support board 3 and the baffle board 6 are on the same horizontal plane, the installation of single-layer gypsum board can be achieved. Figure 2 and 6 In the process, the first gypsum board 14 is removed, and the top planes of the horizontal board 1, the support board 3 and the baffle board 6, as well as the second gypsum board 15 and the lower surface of the covering keel 13 are bonded. The other construction methods are the same.

[0044] The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For those skilled in the art of the present invention, several simple deductions or substitutions can be made without departing from the concept of the present invention, and all of these should be considered as within the scope of protection of the present invention.
