Description
Technical field
The utility model relates to a kind of moistureproof fire resistant air-duct.
Background technique
Fire resistant air-duct also claims the airduct of preventing fires, and is the safe life-saving system in the building, be meant building local on fire after, still can keep the airduct of certain hour normal function.The lifesaving safeguards system of smoke evacuation when they are mainly used in fire and forced draft, the difference that generally can be divided into 1h, 2h, 4h etc. requires rank.
Airduct in the building need have the fire resistance property of certain hour, and this also is in recent years, and the lesson after taking place by building fire sums up out.Causing the main factor of casualties in fire is the suction of flue gas, and causes the reason of fortune loss to be because airduct avalanche and cause the boundless and indistinct fireman of smog can not in time enter due to the scene sues and labours in big fire.The mode that solves in modern architecture has only one: the operating time time of evacuating personnel (at least greater than) that guarantees anti-, purging system continuous and effective.Guarantee that airduct has the necessary basis that certain Duration of fire resistance is the purging system continuous firing.The effect that airduct keeps Duration of fire resistance to reach is:
Still can remove flue gas after fire is controlled;
At present, the fire resistant air-duct that adopts on the market mainly contains iron sheet airduct, glass fibre composite air duct, magnesia oxychloride cement airduct, hydraulicity inorganic glass fibre reinforced plastic blast pipe; Though they are still playing an important role at present, but because their intrinsic material behaviors and assembling mode (mainly do the bound edge material or adopt sealer to carry out bonding) with the thick iron sheet of 0.60mm, as galvanized steel plain sheet in the iron sheet airduct easy deformation and damage under combustion flame, though it is made that other three kinds of airducts are nonflammable material, fire resistance period is short partially and material fragility is bigger, and the construction consume is big, inleakage is big, resisting wind press capacity is poor, and is yielding mouldy at wet environment, not acid resistant alkali; All these deficiencies have limited the extensive utilization (wet area particularly is as basement, generator machine room, tunnel, open-air pipeline or the like engineering) of fire resistant air-duct.
