Description

Technical Field

[0001] This utility model relates to the field of fire-resistant air duct technology, specifically a prefabricated assembled graphite silicon fire-resistant air duct. Background Technology

[0002] Fire-resistant ducts are a type of fire-fighting duct used in smoke control and exhaust systems in building projects. They come in various types, including metal ducts, fiberglass ducts, stainless steel ducts, and various composite ducts. Currently, fire-resistant ducts are mainly of two types: galvanized metal ducts with an outer refractory cladding and composite fire-resistant ducts. The wall material of composite fire-resistant ducts primarily consists of two layers of color-coated steel plates, with a fire-resistant layer in between. Graphite-silica fire-resistant board, as a lightweight and high-temperature resistant refractory material, meets the fire resistance requirements of new smoke control regulations for smoke control and exhaust ducts. It overcomes the shortcomings of silicate fire-resistant boards, such as heavy weight and poor insulation, and also solves the problems of low strength and easy fiber shedding of flexible fire-resistant materials such as rock wool and aluminosilicate wool. Therefore, graphite-silica fire-resistant ducts using graphite-silica fire-resistant board as the wall material are becoming increasingly popular in the ductwork industry.

[0003] Meanwhile, with the continuous development of the prefabricated building industry, more and more interior decoration is adopting prefabricated design. Therefore, in order to improve the construction efficiency of air ducts, our company has designed a prefabricated graphite silicon PVC duct with graphite silicon PVC as the main body. After the various components of the air duct are prefabricated in the factory, they can be transported to the construction site for rapid snap-fit ​​assembly. This not only gives the air duct good fire resistance, but also greatly improves the construction efficiency of the air duct, making it highly practical. Utility Model Content

The ends of two adjacent composite plates are respectively snapped into the two snap-fit ​​profiles. Corresponding strip-shaped protrusions are provided on the inner walls of both sides of the snap-fit ​​profiles. The composite plates have grooves on both sides that correspond to the strip-shaped protrusions. Sealing strips are provided in the grooves. The strip-shaped protrusions are snapped into the grooves and are in close contact with the sealing strips.

[0007] As a further preferred embodiment of this utility model: the outer side of the corner snap-fit ​​profile is provided with a hanger snap-fit ​​plate for connecting with the duct hanger.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0022] Please see Figure 1-8 This embodiment provides a prefabricated graphite-silicon windproof duct, including two corresponding rectangular flanges 4, with two perpendicular composite plates inserted into the inner side of the rectangular flanges 4, such as... Figure 7 As shown, the composite plate includes a graphite silicon protective plate 11, with metal plates 12 disposed on both the inner and outer sides of the graphite silicon protective plate 11. The graphite silicon protective plate 11 is a conventional and common structure familiar to those skilled in the art, readily available through custom purchase, and is existing technology; therefore, this application will not elaborate further. Figure 1 As shown, in order to better understand the technical solution of this application, as Figure 1 As shown, based on the distribution of the composite panels on the duct body, the composite panels are divided into horizontal composite panels 1 and vertical composite panels 2. Corner clamping profiles 3 are provided at the corners of adjacent horizontal composite panels 1 and vertical composite panels 2. Each corner clamping profile 3 has two mutually perpendicular notches, and the ends of two adjacent composite panels are respectively clamped into the two notches. Figure 2 As shown, the bayonet joint is divided into a horizontal bayonet 6 and a vertical bayonet 7. The end of the horizontal composite panel 1 is locked in the horizontal bayonet 6, and the vertical composite panel 2 is locked in the vertical bayonet 7. To achieve stability after the composite panel is locked in place, eliminating the need for subsequent screw fixing, corresponding strip-shaped protrusions 8 are provided on the inner walls of both sides of the bayonet. Corresponding grooves 9 are provided on both sides of the composite panel. The grooves 9 are formed on the metal plate 12. To ensure the sealing performance after locking, a sealing strip 10 is provided in the groove 9, so that the strip-shaped protrusions 8 are locked in the groove 9 and the strip-shaped protrusions 8 are in close contact with the sealing strip 10. This achieves a stable connection between the composite panel and the corner locking profile 3, ensuring the sealing performance after connection and preventing air leakage at the corners of the duct.

[0023] To further improve the efficiency of on-site construction and installation of air ducts, such as Figure 1 , Figure 5 as well as Figure 8 As shown, a hanger clamping plate 5 for connecting with the duct hanger is provided on the outside of the corner clamping profile 3. Preferably, two hanger clamping plates 5 are provided on each side of the corner clamping profile 3. Bolt mounting holes are provided on the hanger clamping plates 5 so that the hanger of the duct hanger can be clamped between the two hanger clamping plates 5 and quickly fixed by bolts, which can quickly realize the horizontal or vertical (i.e., perpendicular to the ground) installation of the duct.

[0024] like Figure 1 as well as Figure 6 As shown, as a conventional design, a plug groove 13 corresponding to the composite plate is provided on the inner side of the rectangular flange 4. The composite plate is inserted into the plug groove 13. This is a conventional design familiar to those skilled in the art, and will not be described in detail here. Furthermore, in order to ensure the sealing between the plug groove 13 and the composite plate, a sealing gasket 14 is provided in the plug groove 13, and the end of the composite plate abuts against the sealing gasket 14.

[0025] It should be noted that, as a standard design, during prefabrication, the length of the corner snap-fit ​​profile 3 should be the same as the length of the composite panel. The corner snap-fit ​​profile 3 is inserted into the insertion groove 13 of the rectangular flange 4 along with the composite panel, and abuts against the sealing gasket 14 inside it to achieve a good sealing effect.

[0026] Meanwhile, this application no longer limits the cross-sectional shape of the sealing strip 10. It can be designed according to actual needs such as the volume of the duct and the size of the slot 9. It is a conventional setting familiar to those skilled in the art, and this application will not elaborate further. It can be installed by means of bonding, pressing, etc., which is a conventional operation. It can be assembled according to actual needs.

[0027] When assembling the duct, simply snap the composite board and the corner clip profile 3 together to form the duct body, then snap the rectangular flanges 4 onto both sides of the duct body, and fix the insertion slot 13 to the composite board with screws to complete the duct assembly; then install the duct on the duct hanger using the hanger clip plate 5, and connect multiple ducts using the rectangular flanges 4. The operation is convenient.

[0028] It should be noted that the above embodiments are only specific and clear descriptions of the technical solutions and features of this application. Solutions or features that are prior art or common knowledge to those skilled in the art will not be described in detail in the above embodiments.

[0029] Furthermore, the technical solutions of this application are not limited to the above embodiments. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
