Description

Technical Field

[0001] This utility model belongs to the field of interior decoration technology, specifically relating to a concealed smoke curtain. Background Technology

[0002] Smoke curtains are crucial components in building fire protection design, used to delineate smoke zones and prevent the spread of smoke. Installed vertically under the building's ceiling, beams, or suspended ceiling, they create a smoke-collecting space, confining smoke within a specific area and preventing its lateral flow throughout the building. In conjunction with a smoke exhaust system, the smoke curtain's smoke trap effectively traps smoke, facilitating its removal outdoors and improving exhaust efficiency. During a fire, smoke curtains block smoke, providing clear visibility and safe passageways for evacuation, while also creating favorable conditions for fire rescue operations.

[0003] Electric lift smoke curtains are currently the most common type of smoke curtain. To allow space for the lifting and lowering of the device, a space must be left between the suspended ceiling and the ceiling. Currently, in decoration and renovation projects of office buildings, shopping malls, and hotels, smoke curtains are usually finished with a flat joint or with T-shaped aluminum strips suspended below the smoke curtain and concealed within the suspended ceiling. Traditional flat joint finishing often results in an uneven finish due to the smoke curtain rising at varying heights, making it difficult to maintain a flush plane with the ceiling surface and achieving a smooth, aesthetically pleasing transition. Concealing the smoke curtain with suspended aluminum strips within the suspended ceiling is difficult due to aesthetic considerations and limited ceiling space, resulting in poor installation and a less desirable finish.

[0004] For example, patent CN217041131U discloses a fully concealed smoke curtain. This technical solution involves installing anti-collision strips between the ceiling and the wall, so that when the smoke curtain rises, the gypsum board installed below the smoke curtain contacts the anti-collision strips, ultimately achieving a flush finish between the gypsum board and the ceiling, resulting in a better aesthetic appearance. However, in this technical solution, because the gypsum board needs to move relative to the ceiling, a gap must be left between the gypsum board and the ceiling. Furthermore, since the smoke curtain inevitably sways during its raising and lowering process, this gap cannot be very narrow. Therefore, in practice, because the bottom of the smoke curtain in this technical solution is flush with the ceiling, when the two materials are different, the smoke curtain becomes particularly noticeable, making it difficult to achieve a good overall aesthetic effect. Utility Model Content

[0005] The present invention aims to overcome the shortcomings of the existing technology, such as poor connection between the smoke curtain and the ceiling, making it difficult to completely hide the smoke curtain, and provides a hidden smoke curtain to overcome the above-mentioned shortcomings.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0007] A concealed smoke curtain includes a ceiling assembly, a ceiling assembly disposed below the ceiling assembly, and a vertically movable curtain assembly disposed between adjacent ceiling assemblies; it also includes a limiting assembly disposed between adjacent ceiling assemblies that can limit the rising height of the bottom of the curtain assembly, and a passage groove is provided between the limiting assemblies to allow the curtain assembly to rise and fall.

[0008] A receiving cavity is formed between adjacent limiting components, recessed above the ceiling component to accommodate the end of the vertical wall component.

[0009] Smoke curtains are an important fire prevention device indoors, but they typically only function in the event of a fire. The principle behind smoke curtains dictates that a certain number must be installed in prominent locations such as the ceiling. If they are not concealed, they will inevitably affect the aesthetics of the interior design. Therefore, most smoke curtains on the market are electrically operated and retractable, allowing them to descend in case of fire while maintaining a decorative appearance. However, the addition of a retractable mechanism raises the question of how to coordinate the smoke curtain with the ceiling during its raising and lowering process.

[0010] This invention first connects the building and the ceiling assembly using a suspended ceiling assembly, creating a space between the ceiling assembly and the building that can accommodate the retracted wall-mounted component. A gap is reserved between adjacent ceiling assemblies to allow the wall-mounted component to pass through, and a limiting component, higher than the ceiling assembly, is installed in this gap. When the wall-mounted component rises, it passes through a groove between the limiting components. When the bottom of the wall-mounted component abuts against the limiting components, it is prevented from rising further. At this point, the wall-mounted component is completely above the ceiling assembly, and its bottom is accommodated within the receiving cavity. This design further narrows the gap between ceiling assemblies and eliminates the need to consider aesthetic changes caused by differences in wall-mounted and ceiling materials. When the wall-mounted component descends, its bottom does not obstruct the ceiling, ensuring smooth operation of the smoke-blocking curtain.

[0011] Preferably, the wall assembly includes a wall body and corner protectors fixed to the bottom of the wall body; the corner protectors extend to both sides to abut against the limiting components. In practice, a T-shaped corner protector can be formed at the bottom of the wall to cooperate with the limiting components, preventing damage to the wall body and facilitating removal and replacement.

[0012] As a further preferred embodiment, the extension is provided with a first anti-collision layer.

[0013] As a further preferred embodiment, the limiting assembly includes a protective plate for protecting the ceiling assembly, and a limiting plate disposed on the protective plate, with the passage groove formed between the limiting plates on adjacent limiting assemblies. The protective plate is disposed at the edge of the ceiling to reduce wear on the ceiling edge during vertical lifting.

[0014] As a further preferred embodiment, the limiting piece is provided with a second anti-collision layer on the side near the limiting piece.

[0015] As a further preferred embodiment, the limiting component also includes an mounting plate disposed on the protective plate for installation with the ceiling component. In practice, the mounting plate can be sandwiched between the ceiling component and the suspended ceiling component, allowing for construction from below the suspended ceiling and providing ample construction space.

[0016] Preferably, the ceiling assembly includes a suspension rod and a keel fixed below the suspension rod; the keel is fixed to the ceiling assembly.

[0017] As a further preferred embodiment, the ceiling assembly includes a base panel and a cover panel disposed below and in close contact with the base panel.

[0018] As a further preferred option, a fixing device is also included on the ceiling assembly that can simultaneously secure the limiting component, the joists, and the baseboard. In practice, bolts or rivets can be used as the fixing device. In this case, the cladding panel can cover the fixing device, resulting in a more integrated ceiling.

[0019] Preferably, the concealed smoke curtain also includes a motor for driving the curtain assembly to rise and fall.

[0020] Therefore, this utility model has the following beneficial effects:

[0021] (1) By setting up the receiving cavity, the position of the bottom of the smoke curtain is fixed when it rises, so that the smoke curtain can be completely hidden inside the ceiling. At the same time, the interference between the smoke curtain and the ceiling is reduced when the smoke curtain rises, making its operation smoother.

[0022] (2) The limiting device of this utility model is installed from below the ceiling, avoiding installation in the narrow space of the ceiling gap, thus providing a larger construction space and eliminating the need for secondary fixing.

[0023] (3) This utility model has a simple structure and is easy to install. After installation, the ceiling is integrated and there is no need to consider the material difference between the wall and the ceiling. It is suitable for promotion and application in practice.

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Those skilled in the art will be able to implement the present invention based on these descriptions. Furthermore, the embodiments of the present invention described below are generally only a part of the embodiments of the present invention, and not all of the embodiments. Therefore, all other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.

[0031] Example 1:

[0032] like Figure 1 As shown, the concealed smoke curtain of this embodiment first connects the building and the ceiling assembly 20 through the ceiling assembly 10, so that a space is formed between the ceiling assembly 20 and the building that can accommodate the curtain assembly 30. A motor 4 for driving the curtain assembly 30 to rise and fall is fixed on the building. The suspension rod assembly 10 includes a suspension rod 11 directly bolted to the building. The lower end of the suspension rod 11 is welded to a keel 12, which is then fixed to the ceiling assembly 20 by a suspension device. A gap is reserved between adjacent ceiling assemblies 20 to allow the curtain assembly 30 to pass through, and a limiting component 40 with a height higher than the ceiling assembly 20 is installed at this gap.

[0033] The limiting component 40 is specifically as follows: Figure 2As shown, the vertical part is a protective plate 41 that fits tightly against the edge of the ceiling and can prevent friction. On one side of the protective plate 41, a mounting plate 44 extends perpendicularly to the plane of the protective plate 41. The length of the mounting plate 44 can be determined according to the material and structure of the ceiling or suspended ceiling. On the other side of the protective plate 41, a limiting plate 42 extends. The height of the limiting plate 42 is higher than the mounting plate 44 by a certain distance. This distance is the distance at which the final wall hanging can be hidden in the ceiling.

[0034] like Figure 3 As shown, gaps are left between the pre-installed keel 12 to accommodate the limiting component 40 and the ceiling panel component 30. The main structure of the ceiling panel component 30 is a wall body 31 that runs across the gap between the ceiling panels. Metal corner protectors 32 are bolted to its bottom. These corner protectors 32 extend into extensions 33 on both sides of the ceiling panels 20, giving the corner protectors an inverted T-shape. Before installing the limiting component 40, the ceiling panel 31 is lowered to ensure the corner protectors 32 are below the keel 12, leaving installation space. The ceiling panel 20 consists of a base plate 21 directly fixed to the keel 12 and a cover plate 22, which is mainly for aesthetic purposes and is placed below the base plate 21. During installation, the mounting plate 44 of the limiting component 40 is first clamped between the two side keels 12 and the base plate 21, aligning the protective plate 41 with the sides of the keels 12 and the base plate 21. Then, the fixing device 1 passes through the base plate 21, the mounting plate 44, and the keels 12 from bottom to top, achieving integrated assembly of the ceiling and the limiting component 40. Finally, the covering panel 22 is pasted under the base plate 21 to conceal the fixing device 1. At this point, a passageway 1 is formed between the two limiting plates 42, allowing the vertical wall body 31 to rise and fall.

[0035] In this embodiment, the concealed smoke curtain body 31 descends smoothly between the ceiling components 20, and the corner guards 32 descend between the protective plates 41. When the smoke curtain needs to be concealed, the smoke curtain body 31 raises the corner guards 32. After rising a certain distance, the extension 33 abuts against the limiting plate 42, and the smoke curtain body 31 stops rising. At this time, the corner guards 32 are higher than the ceiling components 20 by a certain distance, and the bottom of the smoke curtain components 30 is completely hidden in the receiving cavity 2. It is difficult to detect the presence of the corner guards 32 from the side, making the ceiling more integrated.

[0036] Example 2:

[0037] like Figure 4 As shown, since the corner guard 32 of the vertical wall assembly 30 will collide with the limiting piece 42 during the upward process, repeated collisions may cause the corner guard 32 to fall off. Therefore, one of the differences between this embodiment and Embodiment 1 is that a first anti-collision layer 34 made of rubber is provided above the extension 33. Furthermore, as... Figure 5As shown, in order to reduce the impact force of the rising vertical wall assembly 30 on the limiting assembly 40, a second rubber anti-collision layer 43 is also provided below the limiting piece 42, opposite to the first anti-collision layer 34. When the vertical wall assembly 30 collides with the limiting assembly 40, the anti-collision layer can effectively absorb the impact force and effectively improve the service life of the device.

[0038] The embodiments of this specification have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
