Technical Field

[0001] The present application belongs to the technical field of ventilation ducts, and specifically relates to a prefabricated assembled flue and structure connection joint. Background Art

[0002] Prefabricated flue is a flue system assembled from prefabricated components. It is mainly composed of multiple standardized and modular components, including elbows, straight pipes, flanges, etc. These components are produced, processed and tested in the factory, and then transported to the site for rapid assembly. Prefabricated flue has the advantages of convenient installation, high efficiency, environmental protection and cost saving. Its materials are usually fireproof and corrosion-resistant to ensure the stability and safety of the system. It is widely used in various buildings and commercial places, providing an effective solution for removing smoke and improving the ventilation environment.

[0003] Prefabricated flues have very strict requirements for connections. During the connection process, it is necessary to ensure the sealing and tightness between the various components to prevent smoke leakage and loosening. Flange connection is usually used, and bolts and nuts are used to fix them to ensure a firm connection. In addition, the connection parts need to be treated with anti-corrosion to ensure stability and durability for long-term use. During the connection process, relevant installation specifications and standards should be followed to ensure the integrity and coordination of the flue system. Therefore, the correct connection method is crucial to ensure the safe operation and service life of the prefabricated flue.
