Description

Technical Field

[0001] The invention belongs to the field of composite special doors, and in particular relates to a fireproof composite special door. Background Art

[0002] Special doors are doors with special operating requirements, such as fire prevention, anti-theft, anti-virus, heat preservation, and heat insulation. Rolling shutter doors are a common door product, usually made of metal materials, with a scroll on the top or side of the door body, and the function of rolling up and down through a motor or manual operation. Rolling shutter doors are widely used in commercial places, warehouses, garages and other places. Warehouses that need to meet fire protection requirements generally need to be equipped with fireproof composite special doors, which are generally equipped with composite special doors with fire protection functions, generally rolling shutter doors. However, the existing fire protection structure generally has multiple sprinkler heads above the rolling shutter door. In the event of a fire, water is sprayed downward through the sprinkler head to extinguish the fire, prevent fire, and cool down. However, due to the improvement of people's fire prevention awareness, the probability of fire is not high. When the sprinkler head is not used for a long time, due to external dust, impurities and other particulate matter, the sprinkler head is often blocked. Once a fire occurs and needs to be used urgently, it will cause serious consequences if water cannot be sprayed. For this reason, it is necessary to avoid the blockage of the sprinkler head and improve the convenience and flexibility of the structure. Summary of the invention
