The national standard GB 50981-2014 'building electromechanical engineering earthquake-resistant design standard' sets requirements on the material of smoke-proof pipelines in buildings with different earthquake-resistant grades, the multi-storey buildings in the areas with the temperature of 8 ℃ and below 8 ℃ are required by the standard, galvanized steel plates or steel plates are preferably adopted, and the high-rise buildings and the buildings in the areas with the temperature of 9 ℃ are made of hot galvanized steel plates or steel plates. According to the above specification requirements, the smoke-proof and exhausting air duct should satisfy both the requirement of fire-resistant time and the requirement of steel plate material. In addition, in order to save the space occupied by the air pipe pipeline, the tail end pipeline of the air conditioning ventilation system can be used as the tail end pipeline of the smoke prevention and discharge system. For the dual-purpose pipeline, the requirements of smoke discharge prevention pipelines and the requirements of heat preservation, condensation prevention, sanitation and the like of air-conditioning pipelines are also required to be met. The current common solution is to wrap a fireproof plate after finishing the installation of air-conditioning pipelines (including metal air pipes and heat insulation materials) on a construction site. This scheme is not only the process many, and the construction difficulty, construction cycle length is not convenient for the maintenance operation in later stage. The material waste is serious in the construction process, and each process can damage an upstream process and destroy the integrity of the air pipe.

The inner wall of the steel pipeline is smooth, and the heat-insulating layer is rock wool or a composite magnesium silicate aluminum plate.
The fire-resistant layer is a fireproof plate, and the fireproof plate is fixed on the outer peripheral surface of the heat-insulating layer through keel and screw outer wrapping.
The composite air pipe sections are connected through flange edges of steel pipelines, the flange edges are connected with the outer peripheral surfaces and coated with fireproof laths, and the fireproof laths are connected with the pipelines through screws.
The fireproof plate and the fireproof lath are made of aerogel fireproof plates or calcium silicate fiber plates.
