Through research and analysis, it is found that the equipment not only improves the fire resistance time and fireproof insulation effect of the fireproof air duct, but also provides a first flange and a second flange corresponding to each other at both ends of the air duct main body. The operation is simple, the installation efficiency of the on-site assemblers is improved, and the installation time of the users is saved. However, the following disadvantages still exist to a certain extent.

[0027] During use, the user connects the two docking plates 3 through the first connecting pipe 1 and the second connecting pipe 2.
