Description
Affiliated technical field:
The utility model relates to the wing class of fixed buildings, the two curtain fire resisting shutters of the particularly vertical inorganic double track that moves.
Background technology:
Fireproof door is more and more in real-life application, and people also develop into the high requirement of and surface aesthetic multi-functional to it from the basic demand of initial fire protecting performance to the requirement of fire resisting shutter.Fire resisting shutter of the prior art all is that the curtain sheet of steel is hinged and forms, its not only weight heavier outside, fire prevention, heat insulation and radiation-resistant performance also are difficult to the effect that reaches desirable, and cost is very high.
Summary of the invention:
The purpose of this utility model provides a kind of in light weight, fire prevention, heat insulation and shielding property good and the two curtain fire resisting shutters of lower-cost inorganic double track.
The utility model is realized by implementing following technical scheme: the two curtain fire resisting shutters of a kind of inorganic double track comprise guide rail, are installed in the guide rail and the transmission device that the rolling screen door body moves can be controlled in rolling screen door body moving up and down and the top that is fixed on guide rail.Described rolling screen door body comprises double-deck door curtain, is to have at least the multilayer inorganic material of radiation protective layer, alumina silicate fibre layer and ceramic wool layer to be composited, and connects the all-in-one-piece base in double-deck door curtain bottom.
Because door curtain is made by the multilayer inorganic material, so, except that having fire-proof function, also possessed the good characteristics of radiation proof and effect of heat insulation, and it is in light weight and cost is low.
