However, some structures have outward protrusions such as pipes of different diameters. In such cases, directly installing +A60 insulating cotton is inconvenient, as the protruding pipes may interfere with the +A60 insulating cotton, resulting in poor installation and aesthetics.

[0003] Therefore, there is an urgent need for a fireproof structure that can solve the problem of fireproof materials interfering with the raised structure, thus causing inconvenience in installation. Utility Model Content

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0033] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0035] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0036] This embodiment provides a fireproof structure, such as Figure 1-Figure 4As shown, the fireproof structure includes a first fireproof component 10 and a second fireproof assembly 20. The first fireproof component 10 is positioned at a preset location and has a first thickness. The second fireproof assembly 20 is positioned in the middle of the first fireproof component 10, and the side of the second fireproof assembly 20 is flush with the side of the first fireproof component 10, with the flush surface adhering to the structural bulkhead 50. This creates a receiving space 60 between the second fireproof assembly 20 and the side of the first fireproof component 10 facing away from the flush surface, which can accommodate the protruding structure 40. In this structure, since the second thickness of the second fireproof assembly 20 is lower than the first thickness of the first fireproof component 10, the receiving space 60 is formed. This receiving space 60 can just accommodate the protruding structure 40, thus avoiding interference between the fireproof structure and the protruding structure 40, thereby ensuring ease of installation. The flush surface formed by the outer side of the first fireproof component 10 and the second fireproof assembly 20 ensures the aesthetics of the structure.

[0037] It should be noted that the first fireproof component 10 is made of A60 insulating cotton. A60 insulating cotton has a density of not less than 66 kg / m³. 3 The rock wool is used, and to ensure good fire resistance, the first fireproof component 10 has a first thickness of not less than 70mm. It has a wide range of applications and good fire resistance, making it suitable for passive fire protection. In this embodiment, the first thickness is 70mm; in other embodiments, the specific thickness can be adjusted according to actual needs. Furthermore, the protruding structure 40 can be a pipe, or other irregularly shaped structure with outward protrusions, and the accommodating space 60 can be designed to avoid interference with it.

[0038] like Figure 1 As shown, since the second thickness is less than the first thickness, to ensure a good fire-resistant effect under this condition, the second fire-resistant component 20 includes a second fire-resistant element 21, which is made of aerogel material. Aerogel is a three-dimensional network nanoporous material with a porosity of over 90%, a specific surface area of ​​up to 900 m² / g, and a density as low as 0.002 g / cm³. 3 Aerogel is the lowest density solid to date. With a thermal conductivity of approximately 0.013-0.018 W / (m·K), it is an excellent thermal insulation material, suitable for both cold-weather insulation and heat protection. Due to its lower density and lighter weight compared to A60 insulation cotton, aerogel can reduce its volume while maintaining fire resistance, thus minimizing space requirements and allowing for the formation of the aforementioned containment space 60, avoiding interference with the protruding structure 40.

[0039] To ensure good fire protection, such as Figure 1As shown, the second fire-resistant component 21 is stacked in at least two layers along its own thickness direction. Stacking multiple layers can effectively improve the fire resistance. In addition, the thickness of each layer of the second fire-resistant component 21 is 9mm-11mm. This thickness not only provides good fire resistance but also high structural strength, facilitates production and manufacturing, and is convenient for installation.

[0040] It should be noted that, due to the excellent fire resistance of aerogel material, in this embodiment, the second fireproof component 21 is provided with only two layers along its thickness direction, and each layer is 10mm thick. Two 10mm thick layers of aerogel are sufficient to produce excellent fire resistance and can effectively reduce manufacturing costs. At the same time, it can leave enough space 60 for the side away from the flat surface, so that the protruding structure 40 can be easily installed in the receiving space 60, which indirectly improves the ease of installation.

[0041] To ensure a consistently good connection, such as Figure 1 As shown, the first fireproof component 10 and the second fireproof assembly 20 are connected by fireproof tape 30. If other adhesives are used for connection, the adhesive may melt due to increased temperature, potentially increasing the risk of the second fireproof assembly 20 falling off; however, using fireproof tape 30 ensures the connection between the two while avoiding the problem of adhesive melting, thus producing a good performance.

[0042] In addition, to ensure good structural strength, such as Figure 1 and Figure 2 As shown, the second fireproof component 20 overlaps with the first fireproof component 10 along its length or width, with each overlap 22 having a length of not less than 100mm. This arrangement improves the connection strength between the second fireproof component 20 and the first fireproof component 10, thereby effectively enhancing the user experience.

[0043] Furthermore, the connection gap between the first fireproof component 10 and the second fireproof component 20 is filled and sealed with a sealant. By setting the sealant, smoke and dust can be prevented from overflowing through the connection gap, thereby ensuring good sealing performance. Further, in this embodiment, the sealant is made of fiberglass cloth. Fiberglass cloth can be used between -196℃ and 300℃, is resistant to chemical corrosion, and is resistant to corrosion from strong acids, strong alkalis, and other organic solvents. It has a low coefficient of friction, can produce an oil-free self-lubricating effect, and will not adhere to any substances.

[0044] To further explain, in order to improve the manufacturing speed of fireproof structures, such as Figure 1 and Figure 2As shown, install studs 23 in the area where aerogel needs to be laid, then continuously lay two 10mm thick layers of aerogel (second fireproof component 21) in that area, and completely seal the perimeter with fiberglass cloth. Finally, cut off the excess studs 23 and put on the cap. The operation is simple and convenient, and can effectively improve the production speed.

[0045] In summary, using the fireproof structure in this embodiment not only solves the problem of interference between the fireproof material and the raised structure 40, but also ensures ease of installation and aesthetic appeal.

[0046] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
