[0002] With the rapid development of modern building technology, especially the increasing number of high-rise buildings, commercial complexes and public facilities, higher requirements are put forward for the safety, aesthetics and functionality of the internal space of buildings. In these buildings, the ceiling, as an important part of the indoor space, not only undertakes the basic functions of separating spaces and hiding pipelines, but also gradually becomes a key factor in enhancing the overall aesthetics and quality of the building. However, traditional ceiling structures often appear powerless in the face of emergencies such as fires, and their fireproof performance is limited. Once a fire occurs, it is easy to become a passage for the spread of fire, seriously threatening the safety of people's lives and property.

[0003] In addition, the installation of traditional ceiling systems mostly relies on complex support structures and cumbersome on-site operations, which not only have a long construction period, but also cause great changes to the building structure, increasing the construction cost and maintenance difficulty. At the same time, with the growing demand for personalization and artistry of the indoor environment, the traditional ceiling with a single function has been difficult to meet the diversified needs of modern buildings.

[0022] Preferably, the frame assembly includes four L-shaped keels spliced end to end in sequence;

[0023] The vertical surface of the L-shaped keel is attached and installed to the limiting end below the ceiling through the third connector, and the horizontal surface of the L-shaped keel is used to support the second rock wool layer.

[0024] Preferably, the frame assembly further includes a metal support plate for supporting the third gypsum board layer.

[0050] As Figures 1-10 shown, a hoisting fireproof ceiling structure includes multiple groups of upper keel assemblies 1, multiple groups of lower keel assemblies 2, and a frame assembly 3;

[0051] The multiple groups of upper keel assemblies 1 are installed at intervals below an external ceiling 100 through first connectors 10, and there is a first cavity between the multiple groups of upper keel assemblies 1 and the ceiling 100;

[0052] The multiple groups of lower keel assemblies 2 are installed at intervals below the upper keel assemblies 1 through second connectors 20, and the multiple groups of upper keel assemblies 1 and the multiple groups of lower keel assemblies 2 are vertically arranged;

[0053] The interior of the frame assembly 3 is enclosed and installed around the multiple groups of upper keel assemblies 1 and lower keel assemblies 2, and the exterior of the frame assembly 3 is fitted and installed to a limiting end 200 below the ceiling 100 through a third connector 30;

[0054] The cross-section of the upper keel assembly 1 is in an X shape. The upper keel assembly 1 includes two upper C-shaped keels 11, and the webs of the two upper C-shaped keels 11 are mutually attached through a fourth connector 40 to form the upper keel assembly 1;

[0055] The cross-section of the lower keel assembly 2 is in an X shape. The lower keel assembly 2 includes two lower C-shaped keels 21, and the webs of the two lower C-shaped keels 21 are mutually attached through a fifth connector 50 to form the lower keel assembly 2;

[0056] A second cavity is formed between the upper part of the multiple groups of lower keel assemblies 2 and the lower part of the upper keel assembly 1. A first gypsum board layer 4 and a first rock wool layer 5 are sequentially installed in the second cavity from top to bottom through a sixth connecting member 60.

[0057] A third cavity is formed between the multiple groups of lower keel assemblies 2 and the frame assembly 3. A second gypsum board layer 6 and a second rock wool layer 7 are sequentially installed in the third cavity from top to bottom through the seventh connecting member 70, and there is a gap space between the second gypsum board layer 6 and the second rock wool layer 7.

[0058] A third gypsum board layer 8 is installed below the multiple groups of lower keel assemblies 2 through the eighth connecting member 80.

[0059] The working principle of the present utility model is mainly based on the combined design of multi-layer structure, modular components and precise connection. Through the mutual cooperation of multiple groups of upper keel assemblies 1, lower keel assemblies 2 and frame assemblies 3, this structure forms a stable ceiling system with high fire resistance performance.

[0060] First, the upper keel assembly 1 is installed at intervals below the external ceiling 100 through the first connecting member 10 to form the top of the support frame. Its X-shaped cross-section design enhances the structural stability and load-bearing capacity.

[0061] Secondly, the lower keel assembly 2 is vertically arranged below the upper keel assembly 1 and fixed through the second connecting member 20. Also adopting the X-shaped cross-section design, it jointly forms a stable support system with the upper keel assembly 1.

[0062] Then, the frame assembly 3 is enclosed and installed around the lower keel assembly 2 and is fitted and installed at the limiting end 200 below the ceiling 100 through the third connecting member 30 to ensure the edge sealing and stability of the entire ceiling structure.

[0063] At the same time, the installation of the fireproof layer and the heat insulation layer is carried out in the cavity formed by the upper keel assembly 1 and the lower keel assembly 2:

[0064] First, in the second cavity formed between the upper keel assembly 1 and the lower keel assembly 2, the first gypsum board layer 4 and the first rock wool layer 5 are sequentially installed through the sixth connecting member 60 to jointly form a fireproof and heat-insulating layer, effectively preventing the spread of fire and reducing heat transfer.

[0065] Secondly, in the third cavity formed between the lower keel assembly 2 and the frame assembly 3, the second gypsum board layer 6 and the second rock wool layer 7 are sequentially installed through the seventh connecting member 70. Moreover, the gap space between the second gypsum board layer 6 and the second rock wool layer 7 further enhances the heat insulation effect.

[0066] The final decorative layer is the third gypsum board layer 8, which is installed below the lower floor joist assembly through the eighth connecting member 80. It not only provides an aesthetic visual effect but also enhances the overall stability of the ceiling structure.

[0067] In summary, the design of the upper and lower floor joist assemblies with an X-shaped cross-section and the combined design of the multi-layer structure significantly improve the fire resistance of the ceiling structure. In a fire, these materials can effectively prevent the spread of flames and reduce the heat transfer rate, buying more time for personnel evacuation and fire rescue.

[0068] Further explanation, the distance of the gap space is d, and d = 15 mm.

[0069] When heat attempts to penetrate the second rock wool layer 7, the gap space with d = 15 mm provides additional thermal resistance, further delaying the heat transfer rate. At the same time, this gap space also promotes air convection, helping to carry away some heat in a fire and reducing the overall temperature.

[0070] Further explanation, the first gypsum board layer 4, the second gypsum board layer 6, and the third gypsum board layer 8 are all formed by laminating gypsum board sub-structures 9;

[0071] The first gypsum board layer 4 includes one layer of gypsum board sub-structure 9;

[0072] The second gypsum board layer 6 includes two layers of gypsum board sub-structures 9;

[0073] The third gypsum board layer 8 includes three layers of gypsum board sub-structures 9.

[0074] As Figure 6 shown, this multi-layer lamination design increases the thickness and density of the gypsum board layer, thereby improving its fire resistance time, load-bearing capacity, and anti-deformation ability. First, in the event of a fire, each layer of gypsum board sub-structure 9 can resist the flames and high temperatures to a certain extent, and the multi-layer stacking forms a more powerful fire protection barrier, effectively delaying the spread of the fire. At the same time, in a high-temperature environment, traditional single-layer gypsum board is prone to deformation and even collapse. However, the multi-layer laminated gypsum board layer, due to its higher thickness and density, can better resist the influence of thermal stress and reduce the risk of deformation and collapse. Finally, by adjusting the number and thickness of the gypsum board sub-structures 9 in the first gypsum board layer 4, the second gypsum board layer 6, and the third gypsum board layer 8, it can flexibly adapt to the fire protection and decoration requirements in different scenarios.

[0075] Further explanation, the thickness of the gypsum board sub-structure 9 is h1, and h1 = 15.9 mm.

[0076] This selection of the standardized thickness is the result of a comprehensive consideration based on the physical properties of the gypsum board and fire protection requirements. The thicker gypsum board layer substructure 9 can better resist the erosion of fire and high temperature, and extend the fire resistance time of the ceiling structure.

[0077] For further illustration, the thickness of the first rock wool layer 5 and the second rock wool layer 7 is h2, and h2 = 50 mm.

[0078] It is known that the rock wool layer itself has excellent heat insulation performance. Coupled with the 50-mm thickness design, the first rock wool layer 5 and the second rock wool layer 7 can effectively reduce the heat transfer rate during a fire, reduce the temperature rise amplitude in the space below the ceiling, and protect the safety of personnel and property.

[0079] For further illustration, it includes four L-shaped keels 31 spliced end to end in sequence;

[0080] The vertical surface of the L-shaped keel 31 is fitted and installed on the limiting end 200 below the ceiling 100 through the third connecting member 30, and the horizontal surface of the L-shaped keel 31 is used to support the second rock wool layer 7.

[0081] Specifically, the border component 3 is composed of four L-shaped keels 31 spliced end to end in sequence. This design facilitates on-site installation and size adjustment to adapt to the shapes and sizes of different ceilings 50. At the same time, the L-shaped keel 31 is flush with the limiting end 200 below the ceiling 100 and the second rock wool layer 7 respectively through its own shape, and the lower keel component 2 and the L-shaped keel 31 are tightly connected through the third connecting member 30 to enhance its overall stability. At the same time, the visual consistency and aesthetics of the entire ceiling structure are ensured.

[0082] For further illustration, the border component 3 further includes a metal support plate 32, and the metal support plate 32 is used to support the third gypsum board layer 8.

[0083] More importantly, a metal support plate 32 is also installed below the L-shaped keel 31. This design further enhances the bearing capacity and stability of the border component 3. The metal support plate 32 can disperse and bear the weight and pressure from the upper keel component 2 and each layer of gypsum board layer, and maintain the stability and flatness of the structure.

[0084] For further illustration, the first connecting member 10, the second connecting member 20 and the third connecting member 30 include a first adjusting stud and a first adjusting bolt.

[0085] For further illustration, both the fourth connecting member 40 and the fifth connecting member 50 include a second adjusting stud and a second adjusting bolt.

[0086] To further explain, the sixth connecting member 60 , the seventh connecting member 70 and the eighth connecting member 80 are all self-drilling screws.

[0087] During the assembly and fixing process of the suspended fireproof ceiling structure, the requirements under different installation conditions are fully considered and different types of connectors are used to connect the components. They ensure the close connection and stable support between the components while improving the installation efficiency.

[0088] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementations of the present invention without creative work, and these equivalent variations or substitutions are all included in the scope defined by the claims of this application.
