The fireproof casing 201 is protected by the fireproof body 300 to avoid bending that affects the ventilation effect. When a fire occurs indoors, the fireproof sealing material in the gap between the fireproof casing 201 and the fireproof wall 100 is heated and quickly collides, thereby blocking the flame and smoke, and preliminarily improving the fireproof effect of the installation node. The fireproof casing 201 made of PEI material has high fire resistance. Together with the fireproof pipe 208 made of asbestos and the reinforcing ribs 209 made of steel wire, it can not only further enhance the fireproof effect of the duct body 300, but also enhance the overall strength of the installation node, thereby improving the practicability and safety of use of the installation node.
