Description

Technical Field

[0001] This utility model belongs to the field of ceiling technology, and in particular relates to a ceiling with a smoke alarm device. Background Technology

[0002] With the continuous improvement of building safety standards, smoke alarm devices are being used more and more widely in suspended ceiling structures. Traditional ceiling-installed smoke alarms are usually only connected to the ceiling panel by simple fasteners. Smoke needs to diffuse naturally in the space below the ceiling before it can reach the detector, resulting in alarm delay. Although some ceilings are designed with airflow guiding structures, they often use flat inclined plates or fixed air ducts, which provide a single path for guiding smoke and are difficult to adapt to complex fire source locations and indoor airflow interference. This causes smoke to fail to quickly converge on the alarm, delaying the opportunity for fire warning.

[0003] Therefore, it is essential to invent a ceiling with a smoke alarm device. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a ceiling with a smoke alarm device, including a ceiling panel, a ceiling rod, a connecting round seat, a supporting chassis, a drop guide plate, an inflow channel, a smoke alarm, and a chassis tie rod. The ceiling panel is fixedly installed on the indoor roof by the ceiling rod. The connecting round seat fixedly installed below the ceiling panel is fixed to the upper end of several drop guide plates. The lower end of the drop guide plates is fixed to the supporting chassis, and the inflow channel is formed between the supporting chassis. A smoke alarm is fixedly installed on the supporting chassis and is fixedly connected to the indoor roof by the chassis tie rod.

[0005] Preferably, the connecting round seat is installed on the lower surface of the ceiling panel. The connecting round seat has a disc-shaped structure with a rectangular cross-section and is located above the center of the supporting chassis.

[0006] Preferably, the inner and outer diameters of the connecting circular seat are larger than the diameter of the supporting chassis. The supporting chassis is an inverted "T" shaped structure. The upper ends of the chassis tie rods arranged in a circular array on the supporting chassis pass through the ceiling panel above and are connected to the indoor roof.

[0007] Preferably, a smoke detector is fixedly installed at the center of the upper part of the supporting chassis, and chassis tie rods arranged in a circular array are arranged around the smoke detector.

[0008] Preferably, several falling guide plates are fixedly installed between the connecting round seat and the supporting chassis. These falling guide plates, the connecting round seat, and the supporting chassis constitute a complete hollow concave spherical ceiling structure. The inner surface of the falling guide plate is an arc-shaped curved surface, allowing smoke to enter through the inflow channel formed between the falling guide plates and be guided downwards.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] This utility model utilizes a hollowed-out concave spherical ceiling structure and the arc-shaped surface of the falling guide plate to guide smoke from multiple directions in three-dimensional space to converge towards the center. Combined with the inflow channel formed between the supporting chassis and the falling guide plate, the smoke flow resistance is significantly reduced, enabling the smoke alarm to quickly reach the center position. Compared with traditional structures, this shortens the alarm response time by approximately 100%, greatly improving the efficiency of early fire warning.

[0011] In addition, the connecting round base and the supporting chassis of this utility model are connected to the indoor roof through the chassis tie rod to form a stable triangular support structure, which enhances the ceiling's resistance to vibration and wind pressure in complex environments; the inverted "T"-shaped supporting chassis design not only ensures the installation space of the alarm, but also optimizes the smoke diversion path, making it suitable for various places such as commercial buildings and industrial plants.

[0012] The hollow structure of this utility model makes each component relatively independent, and installation can be completed quickly through modular splicing without complex positioning. During maintenance, only a single component (such as the drop guide plate and the supporting chassis) needs to be disassembled to maintain the alarm. Compared with traditional closed ceilings, it improves maintenance efficiency and effectively reduces the later use cost. Attached Figure Description

[0020] As attached Figure 1 To be continued Figure 3 As shown:

[0021] This utility model provides a suspended ceiling with a smoke alarm device, comprising a ceiling panel 1, a ceiling rod 2, a connecting round seat 3, a supporting base 4, a falling guide plate 5, an inflow channel 6, a smoke alarm 7, and a base tie rod 8. The ceiling panel 1 is fixedly installed on the indoor roof via the ceiling rod 2. The connecting round seat 3, which is fixedly installed below the ceiling panel 1, is fixed to the upper ends of several falling guide plates 5. The lower ends of the falling guide plates 5 are fixed to the supporting base 4. The inflow channel 6 is formed between the supporting bases 4. The smoke alarm 7 is fixedly installed on the supporting base 4 and is fixedly connected to the indoor roof via the base tie rod 8.

[0022] Furthermore, the connecting round base 3 is integrally molded from high-strength aluminum alloy, with a disc-shaped structure and a rectangular cross-section, combining lightweight and structural strength. The connecting round base 3 is fixed to the center of the lower surface of the ceiling panel 1 with countersunk screws, ensuring stable installation without affecting the flatness of the ceiling panel 1. As the upper connection hub of the ceiling structure, this component is designed with a diameter larger than that of the supporting base 4, typically 1.2-1.5 times the outer diameter of the supporting base 4. This allows the falling guide plate 5 to naturally form the upper contour of a concave sphere after installation, providing a guiding foundation for smoke diversion.

[0023] Furthermore, the supporting chassis 4 is made of stainless steel and machined into an inverted "T" shape to enhance the structure's resistance to pressure and deformation. The smoke detector 7 is bolted to the center of the upper horizontal surface of the supporting chassis 4, and through holes are evenly spaced along the edges for mounting the chassis tie rod 8. Its diameter is smaller than the connecting round seat 3, ensuring a circular drop between them, which, together with the drop guide plate 5, forms a complete concave spherical structure. The supporting chassis 4 is connected to the indoor roof via the chassis tie rod 8, forming a stable triangular support system capable of withstanding ceiling components and additional loads in unexpected situations.

[0024] Furthermore, the chassis tie rod 8 is made of high-strength carbon steel threaded rod with a rust-proof galvanized surface. The lower end of the chassis tie rod 8 is fixed to the horizontal through hole of the supporting chassis 4 with a nut, and the upper end passes through the corresponding hole reserved in the ceiling panel 1 and is anchored to the indoor roof concrete structure with expansion bolts. A rubber shock-absorbing sleeve is fitted on the tie rod part between the ceiling panel 1 and the supporting chassis 4 to prevent structural vibration from affecting the normal operation of the smoke detector 7. The chassis tie rods 8 are evenly distributed in a circular array on the supporting chassis 4 to ensure that the supporting chassis 4 is subjected to balanced force and maintain the stability of the entire ceiling structure.

[0025] Furthermore, the falling guide plate 5 is injection molded from fire-resistant ABS engineering plastic, forming a fan-shaped geometric structure with a smooth arc-shaped curved surface on its inner side. The curvature of the arc matches that of the concave sphere, ensuring smooth smoke flow along the curved surface. There are typically 8-12 falling guide plates 5. Their upper ends are precisely fitted into the side grooves of the connecting round base 3 via clips, and their lower ends are fixed to the outer side of the vertical part of the supporting chassis 4 using self-tapping screws, forming a complete hollow concave spherical ceiling structure. A 15-20mm gap is reserved between adjacent falling guide plates 5, forming an inflow channel 6. This allows smoke to enter freely while the curved surface guides the smoke towards the center of the supporting chassis 4, achieving an efficient smoke guiding function.

[0026] The working principle is as follows: First, when a fire occurs indoors and smoke is generated, the smoke rises to the ceiling area due to thermal buoyancy. Then, the smoke enters the hollowed-out concave spherical ceiling structure through the inflow channel 6 reserved between the falling guide plates 5. Because the inner side of the falling guide plate 5 is an arc-shaped surface, the smoke flows along the inclined direction of the surface towards the center of the supporting chassis 4, that is, it converges along the lowest point of the concave sphere. Finally, the smoke that converges at the center of the supporting chassis 4 is detected by the smoke detector 7 fixedly installed there, thereby triggering the alarm device and achieving timely fire warning. Throughout the process, the stable support structure formed by the connecting round base 3, the supporting chassis 4, and the chassis tie rod 8 ensures the stable installation of the falling guide plate 5 and the smoke detector 7, ensuring the reliable operation of the smoke guiding and alarm functions.

[0027] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
