[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0032] The core of the utility model is to provide a ceiling double-eyelid corner guard strip, which is integrally formed, is not only easy to install and has a smooth appearance, but also has a stable structure and effectively reduces cracking at the joints of the gypsum board.
[0033] Please refer to Figure 1 The present application provides a double-eyelid corner guard strip for a suspended ceiling, comprising a middle right-angle plate 1 that is bent into an integral shape, and a bottom side plate 2 and a top side plate 3 located on both sides thereof. The end of the bottom side plate 2 away from the middle right-angle plate 1 is integrally provided with a vertical side fixing plate 4, and the side fixing plate 4 is arranged with its back to the middle right-angle plate 1 and is provided with a plurality of first screw holes 5 thereon. The end of the top side plate 3 away from the middle right-angle plate 1 is integrally provided with a horizontal top fixing plate 6, and the top fixing plate 6 is arranged with its back to the middle right-angle plate 1 and is provided with a plurality of second screw holes 7 thereon.
[0034] It should be noted that the design of the keel ceiling is a concave right angle, which is used to improve the aesthetics of interior decoration. The concave right angle is usually formed by two vertical keels.
[0035] Specifically, the central right-angle panel 1 is composed of two mutually perpendicular panels. The bottom side panel 2 is integrally connected to the first panel of the central right-angle panel 1, with the angle between the two panels ranging from 90°±2°. The top side panel 3 is integrally connected to the second panel of the central right-angle panel 1, with the angle between the two panels ranging from 90°±2°. The bottom side panel 2 is overlaid on the first keel, and the top side panel 3 is overlaid on the second keel. The first ends of the first and second keels are respectively perpendicularly connected to the two panels of the central right-angle panel 1. The bottom side panel 2 and the top side panel 3 are both covered with gypsum board, so that the double-eyelid corner guard of the ceiling is placed between the keel and the gypsum board to enhance the strength of the gypsum board.
[0036] The above-mentioned double-eyelid corner guard strip for ceilings is formed by bending in one piece. Compared with the double-eyelid corner guard strip for ceilings formed by riveting and splicing multiple metal plates, it is not necessary to make double-eyelid corner guards through shaping of metal plates one by one. It can be directly installed on the keel as a whole at one time. It is not only convenient to install and has a smooth appearance, but also has a stable structure, which is conducive to enhancing the strength of the gypsum board and reducing the risk of cracking at the joints of the gypsum board. In addition, when installing the double-eyelid corner guard strip for ceilings, the bottom side plate 2 is covered on the first keel, and the top side plate 3 is covered on the second keel. The first ends of the first keel and the second keel are respectively vertically connected to the two plate bodies of the middle right-angle plate 1. The top fixing plate 6 is aligned with the second end of the second keel and is fixed to the roof by screws. The side fixing plate 4 is aligned with the second end of the second keel and is fixed to the vertical wall by screws. As a result, the firmness of the installation of the double-eyelid corner guard strip for ceilings is improved, and the strength of the gypsum board is further enhanced, thereby effectively reducing the risk of cracking at the joints of the gypsum board.
[0037] Preferably, the top fixing plate 6 and the top side plate 3 are mutually perpendicular, which not only facilitates the alignment of the top fixing plate 6 with the second end of the second keel, but also allows the top fixing plate 6 to be close to the roof when the top side plate 3 rests on the roof, facilitating the fixation of the top fixing plate 6. And / or, the side fixing plate 4 and the bottom side plate 2 are mutually perpendicular, which not only facilitates the alignment of the side fixing plate 4 with the second end of the first keel, but also allows the side fixing plate 4 to be close to the wall when the bottom side plate 2 is lowered to the vertical wall, facilitating the fixation of the side fixing plate 4.
[0038] Based on the above examples, please refer to Figure 1 The side fixing plate 4 extends back toward the middle right-angle plate 1 to form a first preset width, and the first preset width is less than the thickness of the gypsum board covering the bottom side plate 2.
[0039] Specifically, the side fixing plates 4 are approximately 5 mm wide, and the thickness of the gypsum board covering the bottom side plates 2 is approximately 10 mm, making the side fixing plates 4 narrower than the thickness of the gypsum board covering the bottom side plates 2. This allows the gypsum board to cover the side fixing plates 4 vertically while also leaving space for putty powder filling horizontally, making it easier to fill the space between the gypsum board and the side fixing plates 4 with putty powder. This ensures the flatness of the ceiling while also strengthening the connection between the side fixing plates 4 and the gypsum board, further reducing the risk of cracking in the gaps in the gypsum board.
[0040] Based on the above examples, please refer to Figure 1 The top fixing plate 6 extends back toward the middle right-angle plate 1 to form a second preset width, and the second preset width is less than the thickness of the gypsum board covering the top side plate 3.
[0041] Specifically, the width of the top fixing plate 6 is approximately 8 mm, and the thickness of the gypsum board covering the top side panels 3 is approximately 10 mm, making the width of the top fixing plate 6 smaller than the thickness of the gypsum board covering the top side panels 3. In this way, after the gypsum board is covered on the top side panels 3, it can not only cover the top fixing plate 6 in the horizontal direction, but also reserve space for filling putty powder in the vertical direction, making it easier for putty powder to be filled in the space between the gypsum board and the top fixing plate 6. On the one hand, this ensures the flatness of the ceiling, and on the other hand, it strengthens the connection strength between the top fixing plate 6 and the gypsum board, further reducing the risk of cracking in the gaps in the gypsum board.
[0042] Based on the above examples, please refer to Figure 1 The first screw hole 5 is an oblong hole and extends along the length direction of the side fixing plate 4.
[0043] It can be understood that the oblong hole is generally composed of two semicircular holes and a long hole located between the two. The oblong hole has a certain length. The position of the side fixing plate 4 on the vertical wall can be adjusted by adjusting the position of the screw in the oblong hole to adjust the gap between the side fixing plate 4 and the vertical wall.
[0044] Based on the above examples, please refer to Figure 1 , the second screw hole 7 is an oblong hole and extends along the length direction of the top fixing plate 6. Similarly, the position of the top fixing plate 6 on the roof can be adjusted by adjusting the position of the screw in the oblong hole to adjust the gap between the top fixing plate 6 and the roof.
[0045] Based on the above examples, please refer to Figure 1 The bend between the bottom side panel 2 and the middle right-angle panel 1 is at a right angle. In other words, the angle between the bottom side panel 2 and the first plate body of the middle right-angle panel 1 is 90°, which not only helps the bottom side panel 2 to be close to the first keel, facilitating the installation and fixation of the two, but also helps to improve the structural strength.
[0046] Based on the above examples, please refer to Figure 1 The bend between the top side panels 3 and the middle right-angled panel 1 is at a right angle. In other words, the angle between the top side panels 3 and the second plate body of the middle right-angled panel 1 is 90°, which not only helps the top side panels 3 to fit closely against the second keel, facilitating their installation and fixation, but also helps to improve the structural strength.
[0047] Based on the above examples, please refer to Figure 1 The bending part between the top side plate 3 and the middle right-angle plate 1 is set as an upper arc edge 8 protruding outward.
[0048] The upper arc edge 8 has the following advantages: First, it can be used as a decorative flange structure to increase the aesthetics of the ceiling shape; second, it can not only provide a reference for nailing, alignment, and leveling of the gypsum board covered on the top side panels 3, but also provide support for the gypsum board covered on the top side panels 3 to prevent the gypsum board from sliding, shifting, or even tilting to the side during the ceiling process, thereby ensuring the flatness and aesthetics of the ceiling; third, after the gypsum board is fixed, the thickness of the putty powder required can be determined according to the height of the upper arc edge 8.
[0049] Based on the above examples, please refer to Figure 1 The bending part between the bottom side plate 2 and the middle right-angle plate 1 is set as a lower arc edge 9 protruding outward.
[0050] This lower curved edge 9 has the following advantages: First, it serves as a decorative flange, enhancing the aesthetics of the ceiling; second, it provides a reference for nailing, aligning, and leveling the gypsum board covering the bottom side panels 2, thereby ensuring the flatness and aesthetics of the ceiling. Therefore, the lower curved edge 9 improves the construction speed and aesthetics of the ceiling.
[0051] Based on any of the above examples, please refer to Figures 2 to 4 The specific dimensions of the ceiling double eyelid corner guard are set as follows: the width of the top fixing plate 6 is about 8mm and the length is about 3000mm.
[0052] And / or, the width of the top side plate 3 is about 30 mm and the length is about 3000 mm.
[0053] And / or, the width of the middle right-angle plate 1 adjacent to the top side plate 3 is about 20 mm and the length is about 3000 mm.
[0054] And / or, the width of the middle right-angle plate 1 adjacent to the bottom side plate 2 is about 30 mm and the length is about 3000 mm.
[0055] And / or, the bottom side plate 2 has a width of approximately 28 mm and a length of approximately 3000 mm.
[0056] And / or, the side fixing plate 4 has a width of about 5 mm and a length of about 3000 mm.
[0057] And / or, the first screw hole 5 is a first oblong hole, the semicircle radius at both ends of the first oblong hole is approximately 1.25 mm, the shortest distance between the centers of the semicircles at both ends of the first oblong hole is approximately 4 mm, and the shortest distance between the centers of the semicircles at both ends of the first oblong hole is approximately 3 mm, and the shortest distance between the centers of the semicircles of two adjacent first oblong holes is approximately 16 mm.
[0058] And / or, the second screw hole 7 is a second oblong hole, the semicircle radius at both ends of the second oblong hole is approximately 1.25 mm, the shortest distance between the centers of the semicircles at both ends of the second oblong hole is approximately 4 mm, and the shortest distance between the center of the semicircle of the outermost second oblong hole and the outer edge of the top fixing plate 6 is approximately 4 mm, and the shortest distance between the centers of the semicircles of two adjacent second oblong holes is approximately 16 mm.
[0059] The above-mentioned double-eyelid ceiling corner guards offer a stable structure, minimal deformation, and high load-bearing capacity, providing strong support for the gypsum board, enhancing its strength and effectively reducing cracking at the joints. Of course, the dimensions of the above-mentioned double-eyelid ceiling corner guards can be adjusted based on user needs and the available overhead space at the construction site, and the structural dimensions are not fixed.
