Abstract
A firebreak for ventilation ducts comprises at least one package of parallel fireproofing plates made of a material that expands strongly when exposed to heat, the plates being oriented in the direction of flow in the ventilation duct, with the package filling the cross section of the ventilation duct. To prevent the flames from breaking through and/or to prevent deflagrations into the next fire control sector during the expanding material's reaction time, at least one insert that fills the cross section of the ventilation duct is disposed in the vicinity of the package, said insert being filled of expanded material that is a strongly thermally conductive material.
Claims12
Fire control closure for a ventilation duct, said fire control closure having at least one package of fireproofing plates consisting of a material that expands strongly under heat, said package being oriented in a direction of flow in the ventilation duct and filling a cross section of the ventilation duct, wherein at least one insert that fills the cross section of the ventilation duct is disposed near the package, said insert being filled with expanding material that is strongly heat conducting material.
