Description

Technical Field

[0001] The utility model relates to the technical field of fire-resistant air ducts, in particular to an assembled graphite silicon crystal fire-resistant air duct. Background Art

[0002] Fire-resistant ducts are fire-fighting ducts and are used in smoke and exhaust systems of construction projects. There are various types, including metal ducts, fiberglass ducts, stainless steel ducts and various composite ducts. Among them, composite ducts are the most popular in the market due to their excellent performance. The pipe wall material of the composite fire-resistant duct is mainly composed of two layers of inner and outer color steel plates and a fire-resistant layer located in the middle of the color steel plates. When processing and assembling the composite fire-resistant duct, it is necessary to paste the color steel plates on both sides of the fire-resistant layer, and at the same time, the rectangular outer pipe wall needs to be die-cast separately. The processing technology is relatively complicated and cumbersome, the assembly efficiency is low, and it is impossible to complete the assembly at the construction site.

[0003] With the continuous development of the prefabricated construction industry, more and more interior decoration adopts prefabricated design. Therefore, in order to adapt to the development of the prefabricated construction industry, our company has designed the prefabricated graphite silicon crystal fire-resistant air duct. We use graphite silicon crystal board as the composite main board, and design the traditional color steel plate and outer tube wall into a rectangular installation tube with slots. During assembly, you only need to insert the composite board into the rectangular installation tube and install the connecting flange on both sides of the rectangular installation tube to quickly realize the assembly of a single air duct. The connection of multiple air ducts can be completed by connecting the flanges, and it can be cut and assembled on site according to actual needs, which greatly improves the assembly efficiency of the air duct and the flexibility of on-site assembly construction.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example 1

[0023] See also Figure 1-8 The present embodiment provides an assembled graphite silicon crystal refractory air duct, comprising a rectangular installation tube 1, a wind passage 12 is arranged in the middle of the rectangular installation tube 1, and a rectangular composite plate slot 11 is opened on the side wall of the rectangular installation tube 1. Specifically, Figure 1-4 As shown, the rectangular mounting tube 1 is composed of an outer tube wall 2 and an inner tube wall 3 arranged on the inner side of the outer tube wall 2, and a sealing bottom plate 4 for connecting the outer tube wall 2 and the inner tube wall 3 is arranged on one side of the rectangular mounting tube 1, and a composite plate slot 11 is arranged between the outer tube wall 2 and the inner tube wall 3, and correspondingly, an air passage 12 is located on the inner side of the inner tube wall 3 for ventilation.

[0024] like Figure 1 , Figure 5 , Figure 7 as well as Figure 8 As shown, a composite refractory board 6 is inserted in the composite board slot 11, wherein the composite refractory board 6 is a graphite silicon crystal board, which is a conventional composite board structure that can be directly obtained by technicians in this field through purchase, and is mainly made of graphite and floating bead silicon crystal as the main materials. It is an existing mature technology and will not be repeated in this application; at this time, the outer tube wall 2 and the inner tube wall 3 on the inner and outer sides of the rectangular mounting tube 1 directly replace the traditional color steel plate and the outer protective tube; and the corresponding rectangular flanges 5 are connected to the two sides of the rectangular mounting tube 1 by screws 13. As a conventional design, a flange slot 7 corresponding to the rectangular mounting tube 1 is provided on the rectangular flange 5, and the end of the rectangular mounting tube 1 is inserted in the flange slot 7. The design of the screws 13 is a conventional design, such as Figure 6-8As shown, it is arranged on the groove wall of the flange slot 7, passes through the rectangular installation tube 1 and the composite fire-resistant board 6, so as to realize the fixing of the entire air duct.

[0025] In addition, in order to ensure the sealing performance of the air duct after assembly, a U-shaped sealing gasket 14 is provided in the flange slot 7 and arranged along the inner wall of the flange slot 7. The end of the rectangular mounting tube 1 is inserted into the flange slot 7 and is in close contact with the sealing gasket 14, so that the sealing gasket 14 can seal any gap that may exist between the rectangular mounting tube 1 and the flange slot 7, thereby effectively ensuring the sealing effect of the air duct.

[0026] At the same time, if Figure 1 as well as Figure 6 As shown, in order to further adapt to the needs of the prefabricated building industry and improve the efficiency of on-site installation of air ducts, two rectangular hanger clamping plates 8 distributed along the tube wall are arranged on the outer wall of the outer tube wall 2, and a hanger slot 9 is arranged between the two hanger clamping plates 8, and a plurality of bolt mounting holes 10 are opened on the hanger clamping plates 8; when the air duct is lifted and fixed, the hanger rod can be clamped into the hanger slot 9, and the air duct can be quickly installed and fixed on the hanger by bolts, and the stability of the air duct after installation is ensured; it should be noted that the hanger clamping plate 8 can be directly welded to the rectangular mounting tube 1, which is a conventional setting familiar to technicians in this field and will not be repeated in this application.

[0027] It should be noted that, in practical applications, the overall material of the rectangular mounting tube 1 may preferably be a steel structure in order to achieve the same effect as a traditional color steel plate. The material selection should be common knowledge familiar to those skilled in the art, and this application will not elaborate on the limitation.

[0028] During actual assembly, it is only necessary to insert the composite fire-resistant board 6 into the composite board slot 11 in the rectangular mounting tube 1. As a conventional design, each rectangular mounting tube 1 should correspond to four composite fire-resistant boards 6. After the composite fire-resistant board 6 is inserted into the composite board slot 11, the technician can also choose to add glue as needed to facilitate better fixation of the composite fire-resistant board 6 and the composite board slot 11. Subsequently, the two ends of the rectangular mounting tube 1 are inserted into the flange slot 7 of the rectangular flange 5 and fixed with screws. Finally, the air duct can be installed horizontally or vertically according to needs, and the connection with the air duct hanger can be achieved through the hanger clamping plate 8. It should be noted that, as a common sense, the hanger clamping plate 8 should be processed together with the rectangular mounting tube 1 during processing to avoid on-site welding and affect construction efficiency.

[0029] It should be noted that the above embodiments are only specific and clear descriptions of the technical solutions and technical features of the present application. For those skilled in the art, solutions or features that belong to the prior art or common knowledge are not described in detail in the above embodiments.
