It can effectively isolate the fire area, prevent the fire from spreading to other areas, and reduce the losses caused by the fire. Fireproof air duct is generally made of flame retardant materials, with high temperature resistance, fire resistance and other characteristics, and plays a key role in the event of a fire. Reasonable setting of fireproof air duct in building design is one of the important measures to ensure the safety of personnel and reduce property losses.

[0003] However, the existing fireproof air ducts are generally fixed in place with bolts, which makes it easy for the bolts to rust and age after long-term use, making it inconvenient to inspect and replace the fireproof air ducts. In addition, the bolts of the fireproof air ducts need to be replaced after each installation and inspection, resulting in increased economic costs. In addition, the existing fireproof air ducts are often relatively rigid in appearance and are easily damaged by bumps during daily use, resulting in replacement or reduced use effect.

[0026] Reference Figure 1-5A fireproof air duct that is easy to install includes: an end air duct body 1, a fire blanket 2, an air duct 3, a sandwich air duct body 4, a placement groove 7 and polyurethane glue 9, a bonding and retaining structure is installed on the side of the end air duct body 1, and a combined fixing structure is arranged below the end air duct body 1, and the upper and lower ends of the combined fixing structure are installed with installation structures.

[0027] Reference Figure 1-3 and Figure 5 The bonding and fixing structure includes: a fire blanket 2 and polyurethane glue 9; the fire blanket 2 is surrounded and attached to the outer surface of the end air duct body 1; the polyurethane glue 9 is respectively applied to the outer surface layer of the end air duct body 1 and the inner surface of the fire blanket 2. By applying polyurethane glue 9 to the surface layers of the fire blanket 2, the end air duct body 1 and the sandwich air duct body 4, after the end air duct body 1 and the sandwich air duct body 4 are fixedly connected, the fire blanket 2 can be bonded with the polyurethane glue 9 to prevent the end air duct body 1 and the sandwich air duct body 4 from rotating after the fixed connection is completed, thereby preventing the fire duct from being damaged or causing the fireproof air duct to be damaged. At the same time, the fire blanket 2 has the effects of fire resistance, preventing the spread of fire, extinguishing fire sources, and heat insulation due to its own nature, and has 1. No expiration date; 2. No secondary pollution after use; 3. Easy to carry, simple configuration, quick use, and can be reused when not damaged, so it also has practical use effect.

[0028] Reference Figure 2-3 The combined fixed structure includes: a sandwich air duct body 4; the sandwich air duct body 4 is located between the end air duct body 1, and it can be installed individually or in multiples. At the same time, the material used is consistent with the end air duct body 1, and the basic style and the end air duct body 1 are both cube-like structures. The fixed combined structure is a structure for fixing the end air duct body 1 and the sandwich air duct body 4. It facilitates the multi-stage installation of the fireproof air duct to reduce the single labor burden of the workers, and is easy to combine with the installation structure to facilitate the installation of the new fireproof air duct. At the same time, because it is made of the same material as the end air duct body 1, it will not produce different usage effects during use.

[0029] Reference Figure 2-4The combined fixing structure includes: a top spiral end head 6, a retaining tube 5 and a bottom spiral end head 8; the top spiral end head 6 is installed on the top of the sandwich air duct body 4; the retaining tube 5 is spirally sleeved on the outer layer of the top spiral end head 6; the bottom spiral end head 8 is installed on the bottom of the sandwich air duct body 4; by spirally connecting the top spiral end head 6 and the bottom spiral end head 8 between the retaining tube 5, so that the bottom of the top spiral end head 6 and the top of the bottom spiral end head 8 fit together, so that the end air duct body 1 and the sandwich air duct body 4 can be quickly and effectively installed and connected, which can reduce the lack of work efficiency caused by bolt fixing in multiple directions, and prevent the situation where rust occurs and it is inconvenient to disassemble like bolts.

[0030] Reference Figure 3 , the polyurethane glue 9 is also applied to the outer surface of the sandwich air duct body 4, and the fire blanket 2 is also surrounded and fitted to the outer surface of the sandwich air duct body 4; the placement groove 7 is opened at the bottom of the sandwich air duct body 4, and it is adapted to the fixing tube 5; by specifically describing the connection relationship between the polyurethane glue 9, the fire blanket 2 and the sandwich air duct body 4, it is further clarified that the fire blanket 2 has a fixing effect. At the same time, it is described that the placement groove 7 is opened, so when the end air duct body 1 and the sandwich air duct body 4 are connected, it will not produce a large gap in the middle, which will affect the effect of the fitting connection and cause the fire prevention effect to be weakened.

[0031] Reference Figure 1-5 The end duct body 1 is divided into two styles of design: a style with a bottom spiral terminal 8 and a placement groove 7 at the bottom and a style with a bottom spiral terminal 8 and a retaining tube 5 at the bottom; the full name of the end duct body 1 should be called the upper and lower end duct body, so it can be divided into an upper end and a lower end, which makes it have two different styles, namely, a bottom spiral terminal 8 and a placement groove 7 are respectively arranged at the upper end and the lower end facing the interlayer duct body 4, and a bottom spiral terminal 6 and a retaining tube 5 are arranged.

[0032] Working principle: When using the utility model, workers should select different numbers of sandwich air duct bodies 4 according to the fireproof air ducts of different heights. After the installation of the end air duct body 1 at the bottom is completed, the end of the corresponding sandwich air duct body 4 with the placement groove 7 is aligned with the end air duct body 1 at the bottom, and the bottom spiral end 8 is inserted into the retaining tube 5, and then the sandwich air duct body 4 is spirally tightened to fix the sandwich air duct body 4 and the end air duct body 1 at the bottom. Similarly, the subsequent sandwich air duct bodies 4 are installed as described above until the end air duct body 1 at the top is finally installed. The one with the placement groove 7 at the bottom should be selected. The end duct body 1 is connected as described above, so the new model can be installed quickly and conveniently, and after the installation is completed or during the installation, the polyurethane glue 9 is evenly applied to the outer surface of the end duct body 1 and the sandwich duct body 4, but the applicant recommends applying it after the installation is completed. At the same time, the polyurethane glue 9 is applied to the inner side of the fire blanket 2 that needs to be wrapped, so that the fire blanket 2 can be tightly wrapped around the connected duct body, so that the fire blanket 2 can prevent rotation, and the characteristics of the fire blanket 2 can also be used to prevent fire, heat insulation, and prevent the spread of fire, so as to assist the use of the fireproof duct and ensure life safety.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
