Description

Fireproof air pipe based on foamed ceramic and floor heating thereof Technical Field The invention relates to the technical field of air pipes, in particular to a fireproof air pipe based on foamed ceramics and a floor heating thereof. Background Fire protection ductwork, which is mainly used in the pipelines playing an important role in the fire protection safety system in the building, is used for exhausting smoke and controlling air flow in the fire scene, and the ductwork is generally required to meet specific fire protection safety standards so as to ensure that smoke can be effectively controlled and guided when a fire disaster occurs, and reduce the influence of the smoke on personnel evacuation and fire disaster suppression. In fire, fire prevention tuber pipe system can take away smog from the scene of a fire fast effectively, guide it to safe region or direct exhaust room, this kind of ability of controlling smog is realized through the inside accurate design of tuber pipe and wind-force dynamic management, ensure that smog can not freely spread in the building inside, through effectively controlling smog distribution, fire prevention tuber pipe helps keeping the visibility of escape route, reduce the choking and the sight blocking risk that smog brought, provide critical time for urgent evacuation, therefore, in commercial building, hospitals, schools and high-rise houses, fire prevention tuber pipe is essential safety facilities, they not only accord with the regulation requirement, still ensure personnel's safe important component. Traditional fire-proof air duct materials may not perform well in high temperature environments, are easily deformed or damaged, and may be easily broken or cracked when subjected to impact or pressure, and may contain harmful substances, which may cause a burden to the environment. For the problems in the related art, no effective solution has been proposed at present. Disclosure of Invention In order to overcome the problems, the invention aims to provide a fireproof air duct based on foaming ceramic and a floor heating thereof, and aims to solve the problems that the traditional fireproof air duct material may not perform well in a high-temperature environment and is easy to deform or damage, the traditional material may be easy to crack or generate cracks when being impacted or pressed, and the traditional fireproof material may contain harmful substances and cause burden to the environment.
