Description

Technical Field

[0001] This utility model relates to the field of duct technology, specifically to an integrated prefabricated smoke exhaust duct. Background Technology

[0002] Smoke control and exhaust systems consist of supply and exhaust ducts, shafts, fire dampers, door opening and closing devices, supply and exhaust fans, etc. Smoke control systems are typically set up in positive pressure configurations in stairwells. The smoke exhaust volume of a mechanical smoke exhaust system is directly related to the smoke control zoning. Smoke control facilities in high-rise buildings should be divided into mechanical pressurized air supply systems and natural smoke exhaust systems with operable windows. Air ducts are piping systems used for air transport and distribution. There are two types: composite air ducts and inorganic air ducts. They can be classified according to cross-sectional shape and material. Stainless steel air duct fabrication involves applying sealant (such as neutral silicone sealant) to seams, rivet seams, and the four corners of flanges. Before applying the sealant, surface dust and oil should be removed. According to cross-sectional shape, air ducts can be divided into circular air ducts, rectangular air ducts, and flat oval air ducts, etc. Among them, circular air ducts have the lowest resistance but the largest height dimension and are more complex to manufacture; therefore, rectangular air ducts are mainly used.

[0003] In the prior art, application number 202222932859.9 discloses an integrated prefabricated smoke exhaust duct panel, including a panel body with sealing strips installed around the perimeter. The panel body has assembly devices on its interior and exterior surfaces. The above-mentioned devices are assembled and spliced ​​using simple clamps and plates. This method greatly reduces the strength of the smoke exhaust duct connection, especially at the splice point of two ducts, where skewing is likely to occur, and the sealing and load-bearing capacity of the splice are poor. Furthermore, the duct needs to be protected by a protective bracket installed on the outside during use. The long-term reinforcement and suspension of the protective bracket can cause the duct to deform due to prolonged pressure between the duct and the installation position of the protective bracket.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0029] Example 3

[0030] like Figure 1-4As shown, an integrated prefabricated smoke exhaust duct according to an embodiment of the present invention includes a duct body 1, a first mounting frame plate 2, and a second mounting frame plate 3. The left end of the duct body 1 is fixedly connected to the right side of the first mounting frame plate 2, and the right end of the duct body 1 is fixedly connected to the left side of the inner wall of the second mounting frame plate 3. An assembly frame 4 is fitted on the outer side of the duct body 1. Reinforcing protrusions 5 are fixedly connected to the four sides of the outer wall of the second mounting frame plate 3. A movable frame 11 is movably fitted on the outer wall of the duct body 1.
