Abstract
Description
Technical Field
[0001] This utility model relates to the field of building materials processing technology, and more specifically, to an aluminum alloy corner strip for interior decoration of buildings. Background Technology
[0002] Interior trim strips are decorative strips applied to the walls or ceilings of a building's interior space, or to the corners where walls and ceilings meet, to protect the walls, ceilings, or their corners and to provide an aesthetic and decorative effect.
[0003] Currently, the traditional method of splicing interior decorative moldings with wallpaper or plaster layers mainly involves plaster workers using a cutter to cut the wallpaper and attach it to the edge of the decorative molding. Over time, this splicing process can easily lead to cracking at the seam between the wallpaper and the decorative molding, affecting its appearance. Moreover, this traditional manual cutting of wallpaper can easily result in uneven edges, which also affects the splicing effect at the seam.
[0004] Therefore, it is necessary to propose an aluminum alloy corner strip for interior building decoration to solve the above problems. Utility Model Content
[0005] This utility model provides an aluminum alloy corner strip for interior building decoration, which solves the problems of uneven cutting and easy delamination at the seams of existing building decorative corner strips and wallpaper, resulting in unsightly splicing.
[0006] According to one aspect of the present invention, an aluminum alloy corner strip for interior decoration is provided, which is installed at the corner where the ceiling and the wall intersect. The aluminum alloy corner strip includes a main body with an L-shaped cross-section. The main body includes an upper plate and a side plate. The upper plate and the side plate are connected to each other at a 90-degree angle. The end of the upper plate extends downward to form a guide edge. The side end face of the side plate is provided with a U-shaped buckle. The free end of the buckle extends to the opposite side to form a retaining edge. A buffer strip is detachably installed inside the buckle. The buffer strip located on the outer end face of the buckle extends outward to form a connecting edge.
[0007] Based on the above scheme, the connection between the upper plate and the side plate is arc-shaped.
[0008] Based on the above scheme, preferably, the guide is provided with an open-shaped embedding groove at the corner of the inner edge surface where it connects to the upper plate.
[0009] Based on the above scheme, a preferred embodiment is provided at the lower corner where the buckle connects to the side plate body, where an embedding groove is provided.
[0010] Based on the above scheme, the top surface of the upper plate and the top surface of the buckle are provided with anti-slip grooves.
[0011] This utility model discloses an aluminum alloy corner strip for interior building decoration. The main body is designed in an L-shape, with buckles on the side panels. The buffer strips inside the buckles extend outward to form connecting edges to the wooden beams or aluminum alloy hanging beams of the surrounding ceiling for installation. The upper side panel is attached to the ceiling, and the side panels are attached to the edge of the wooden beams of the ceiling. The main body of this utility model and the wall form a space, creating a sense of layering and improving the overall aesthetics.
[0012] On the other hand, the aluminum alloy corner strip for interior decoration of this utility model also has an open-shaped embedding groove on the upper plate and the side plate. When wallpaper is applied to the ceiling and / or the wall, its edge can be directly pressed into the embedding groove, thereby effectively avoiding uneven cutting that results in insufficient aesthetics. At the same time, it can also effectively avoid the problem of cracking at the splice due to loose wallpaper. Attached Figure Description

[0027] Please see Figure 1 and combined Figure 2 and Figure 3 As shown, this utility model discloses an aluminum alloy corner strip for interior decoration of buildings. The aluminum alloy corner strip is used to be installed at the junction of the ceiling 2 and the wall 3. Its purpose is to avoid the need for a suspended ceiling, or to simplify the floor height occupied by the suspended ceiling, while creating a more beautiful three-dimensional spatial effect.
[0028] The aluminum alloy corner strip of this utility model is installed at the corner where the ceiling 2 and the wall intersect. The aluminum alloy corner strip includes a main body 1 with an L-shaped cross section. The main body 1 includes an upper plate 11 and a side plate 13. The upper plate 11 and the side plate 13 are connected to each other at a 90-degree angle, and the two are connected by an arc-shaped transition.
[0029] The upper plate 11 of this utility model extends downward to form a guide edge 12. The side end face of the side plate 13 is provided with a U-shaped buckle 14. The free end of the buckle 14 extends to the opposite side to form a retaining edge 15. A buffer strip 16 is detachably installed inside the buckle 14. The buffer strip 16 located on the outer end face of the buckle 14 extends outward to form a connecting edge 17.
[0030] In use, when the ceiling 2 is suspended, the connecting edge 17 can be connected to the suspended structure on the ceiling 2 to achieve its fixation; when the ceiling 2 is not suspended, a leveling plate can be laid on the ceiling 2, and then the connecting edge 17 can be combined with the leveling plate, while the edge of the side panel 13 is attached to the wall 3 adjacent to the ceiling 2. Then, wallpaper can be applied to the suspended structure or leveling plate and laid to the inner side of the side panel 13 of this application. The wallpaper applied to the wall 3 is laid to the inner edge of the upper panel 11. This not only covers the joint between the wall 3 and the aluminum alloy corner strip, but also covers the joint between the aluminum alloy corner strip and the ceiling 2, avoiding the problem of loosening at the joint between the aluminum alloy corner strip and the wallpaper. Moreover, in the structural design of the aluminum alloy corner strip, a groove is formed between the wall 3 and the ceiling 2, making the spatial layer more distinct and the effect better, improving the aesthetic appearance.
[0031] Meanwhile, this utility model has an arc-shaped structure at the connection between the upper plate 11 and the side plate 13.
[0032] Furthermore, to avoid uneven wallpaper cutting and loose wallpaper joints, the guide edge 12 of this utility model is provided with an open-shaped embedding groove 18 at the corner of the inner edge surface connected to the upper plate 11, and the buckle 14 of this utility model is provided with an embedding groove 18 at the lower corner of the connection between it and the side plate 13.
[0033] The design of the recessed groove 18 allows the edges of the wallpaper to be pressed together to avoid the joints being exposed and affecting its appearance. At the same time, the recessed groove 18 can also lock the edges of the wallpaper to prevent it from coming loose.
[0034] It should be noted that the present invention also provides anti-slip grooves 19 on the top surface of the upper plate 11 and the top surface of the buckle 14. Through the design of the anti-slip grooves, when the adhesive is brushed on its surface during installation, its adhesion can be improved.
[0035] This utility model discloses an aluminum alloy corner strip for interior decoration of buildings. The main body 1 is designed in an L-shape. The side plate 13 of the main body 1 is provided with a buckle 14. The buffer strip 16 inside the buckle 14 extends outward to form a connecting edge 17 to be installed on the wooden beam or aluminum alloy hanging beam of the ceiling 2 of the surrounding suspended ceiling. The upper side plate is attached to the ceiling 2, and the side plate 13 is attached to the edge of the wooden beam of the ceiling 2. The main body 1 of this utility model and the wall 3 are used to form a space, creating a sense of layering and improving the overall aesthetics.
[0036] On the other hand, the aluminum alloy corner strip for interior decoration of this utility model also has an open-shaped embedding groove 18 on the upper plate 11 and the side plate 13. When wallpaper is applied to the ceiling 2 and / or the wall 3, its edge can be directly pressed into the embedding groove 18, thereby effectively avoiding uneven cutting that would result in insufficient aesthetics. At the same time, it can also effectively prevent the problem of cracking at the splice due to loose wallpaper.
[0037] Finally, the method described in this application is merely a preferred embodiment and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
