Abstract
Description
Technical Field
[0001] This utility model relates to the field of ceiling decoration technology, and in particular to a decorative device for a ventilation window inside a ceiling. Background Technology
[0002] In the field of architectural decoration, ceiling design not only needs to meet aesthetic requirements but also needs to consider functionality, especially practical requirements such as ventilation and lighting. Ventilation windows within the ceiling are usually directly exposed to the interior, making the coordination of their appearance with the overall decorative style a design challenge.
[0003] Due to fire safety regulations, some functional rooms require high windows to have smoke extraction capabilities. However, some high windows are installed inside the ceiling, which makes it difficult to open them properly and maintain the aesthetics of the overall structure. Traditional ventilation openings often use simple metal grilles or louver structures, which are monotonous, lack decorative appeal, and can easily create visual clashes with upscale interior design.
[0004] Based on this, the present invention proposes a decorative device for ventilation windows inside a suspended ceiling. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model proposes a decorative device for ventilation windows inside the ceiling, which can both open the high window inside the ceiling to achieve ventilation and meet aesthetic requirements.
[0006] The technical solution to achieve the purpose of this utility model is as follows: a decorative device for a ventilation window in a suspended ceiling, including a pair of first and second hangers and multiple pairs of third hangers and a window frame. The window frame is set on one side of the wall. The bottom of each first and second hanger is connected to an L-shaped connecting plate by a nut. The bottom of each third hanger is connected to a connecting block by a nut. It also includes a support component.
[0007] A support assembly is disposed at the bottom of the boom three;
[0008] The support assembly includes a cross brace fixedly installed between each pair of adjacent connecting blocks, and a keel is fixedly installed between the connecting blocks and the cross brace.
[0009] In some embodiments, inorganic fireproof plate one and inorganic fireproof plate two are fixedly installed on one side of each pair of L-shaped connecting plates located on the first and second rods, and a pair of U-shaped connecting plates are fixedly installed between the inorganic fireproof plate one and inorganic fireproof plate two.
[0010] In some embodiments, a keel 2 is fixedly installed between the inorganic fireproof board 1, the inorganic fireproof board 2, and a pair of U-shaped connecting plates. Ventilation holes are provided on the inorganic fireproof board 1, and a grille is fixedly installed on the ventilation holes.
[0011] In some embodiments, the bottoms of the first and second keels are jointly fixed with double-layer gypsum board using drywall screws.
[0012] In some embodiments, a ventilation window is movably mounted on the window frame, and a hand-cranked window opener is fixedly installed between the ventilation window and the window frame.
[0013] Compared with existing technologies, the significant advantages of this invention are:
[0014] Firstly, this utility model can effectively beautify and decorate the ventilation device by using double-layer gypsum board, and the opening of high windows can be achieved simply and efficiently using existing hand-cranked window openers. Thus, it can both achieve ventilation and smoke extraction by opening high windows in the ceiling, and also meet aesthetic requirements.
[0015] Secondly, this utility model is not only simple in structure and easy to construct, but also low in cost, and can achieve a good effect of opening high windows for ventilation and smoke extraction while maintaining an aesthetically pleasing appearance.
[0016] This solution addresses the existing problems where fire safety regulations require some functional rooms to have high windows with smoke extraction capabilities, and some high windows are installed inside the ceiling, making it difficult to open them properly and maintain the aesthetics of the overall structure. Traditional ventilation openings often use simple metal grilles or louver structures, resulting in monotonous designs and a lack of decorative appeal. Attached Figure Description

[0024] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.
[0025] This utility model provides an improved decorative device for a ventilation window inside a suspended ceiling. The technical solution of this utility model is as follows:
[0026] like Figures 1-4 As shown, a decorative device for a ceiling-mounted ventilation window includes a pair of hangers 1, 2, and multiple pairs of hangers 3, as well as a window frame 7. The window frame 7 is set on one side of the wall. The bottom of each hanger 1 and 2 is connected to an L-shaped connecting plate 11 by a nut, and the bottom of each hanger 3 is connected to a connecting block 12 by a nut. The device also includes a support assembly. The hangers 1, 2, and 3 provide stable support for the installation of the support assembly, including the ventilation and smoke extraction device.
[0027] Support assembly, which is located at the bottom of the hanger rod 3.
[0028] The support assembly includes a cross brace 14 fixedly installed between every two adjacent connecting blocks 12. A keel 13 is fixedly installed between the connecting blocks 12 and the cross brace 14. The keel 13 and the cross brace 14 can form a keel frame, which facilitates the installation of a stable foundation for subsequent components.
[0029] Furthermore, inorganic fireproof board 14 and inorganic fireproof board 20 are fixedly installed on one side of each pair of L-shaped connecting plates 11 located on hanger 1 and hanger 2 respectively. A pair of U-shaped connecting plates 17 are fixedly installed between inorganic fireproof board 14 and inorganic fireproof board 20. The inorganic fireproof board 14 and inorganic fireproof board 20 not only improve the fireproof effect at the window, but also provide a certain support effect.
[0030] Furthermore, a keel 2 15 is fixedly installed between the inorganic fireproof board 1 4, the inorganic fireproof board 2 10, and a pair of U-shaped connecting plates 17. Ventilation holes 5 are opened on the inorganic fireproof board 1 4, and a grille 6 is fixedly installed on the ventilation holes 5. The ventilation holes 5 and the grille 6 can effectively achieve the effect of ventilation and smoke exhaust.
[0031] Furthermore, the bottom of both keel one 13 and keel two 15 are fixed with double-layer gypsum board 16 by drywall screws. The double-layer gypsum board 16 greatly improves the aesthetics of the overall structure.
[0032] Furthermore, a ventilation window 8 is movably installed on the window frame 7, and a hand-cranked window opener 9 is fixedly installed between the ventilation window 8 and the window frame 7. By using the hand-cranked window opener 9, the high window inside the ceiling can be opened, which can achieve the effect of ventilation and smoke exhaust, while also satisfying the overall aesthetics.
[0033] The specific working method is as follows: After fixing the first hanger 1, the second hanger 2, and the third hanger 3 in sequence according to their installation positions, fix the first keel 13, the second keel 15, and the cross brace keel 14. Then, fix the inorganic fireproof board 14 and the inorganic fireproof board 20 to one side of the first hanger 1 and the second hanger 2. Fix the double-layer gypsum board 16 to the keel frame using drywall nails. Open ventilation holes 5 on the inorganic fireproof board 14 and fix the appropriate grille 6 at the ventilation holes 5. Finally, install a hand-cranked window opener 9 between the ventilation window 8 and the window frame 7, so as to easily open the high window in the ceiling to achieve the effect of ventilation and smoke exhaust.
[0034] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
