Definitions

  • the invention particularly relates to a fire retardant closure in the form of a curtain.
  • Fire-retardant closures are already known in the form of fire-retardant gates. These gates contain in their core and at their edges a stiff substrate, on which a fire-retardant and when heated foaming material is attached. Such fire-retardant gates have the disadvantage that they have a large weight, whereby it is necessary to provide them with a motor for the drive. Another disadvantage is that such gates and doors are quite expensive due to the presence of an engine that opens and closes these shutters.
  • Yet another disadvantage is that such doors are quite bulky in volume and therefore can not be used everywhere. Yet another additional disadvantage is that you always have to provide the walls of the opening or of the guides of the door also with a thermally expanding material. In the known fire-resistant doors there is always a certain amount of space between the wall and the gate. As a result, you must always attach a profile between the walls of the port to be closed, in which a thermally expanding material is attached. In the event of fire or heating, the foaming of this material should ensure that the space between the wall and the gate is closed.
  • a fire protection mat in which a thermally expanding material is added between two layers of fabric.
  • a disadvantage of this embodiment is that the curtain in case of fire, an increased tensile load on the side guides can learn.
  • a fire-resistant curtain known in which intumescent material between different layers of fabric is arranged. In case of fire, the following material will give off steam in the loops, so that the curtain is cooled. Even such a curtain can experience an increased tensile load on the lateral guides in case of fire.
  • the present invention aims to provide a solution to the above and other disadvantages.
  • the invention solves the problem by a conclusion with the features of claim 1.
  • the curtain can be rolled up or folded as desired, so that it can be lowered in a compact form above a gate or other openings in a wall or wall to the conclusion of the above opening and so in case of fire, a barrier against the overturning of the fire is formed by said opening.
  • thermally expanding material is understood as meaning, in particular, intumescent material which inflates under the action of heat.
  • the thermally expanding material is thus in particular such that it shows an irreversible increase in volume under the action of heat.
  • Examples are expanded graphite or expanded mica.
  • thermally expanding or intumescent material can be present for example as solid granules.
  • the thermally expanding material is present as a solid or as a paste.
  • the paste may be applied to an inner side of the fabric facing the inner space.
  • chambers, subdivisions or tunnels are formed in the inner space.
  • a fire-resistant finish in which the height of the slats is greater than the distance between the chambers. It is also beneficial if the chambers and the slats cover each other.
  • the fire-resistant finish can also be rolled up or foldable.
  • the tunnels are configured to expand when activated in the direction of the fire.
  • the tunnels are formed by strips of fabric attached between and bonded to the at least two layers of fabric so as to form boundaries and separate the tunnels.
  • the fabric strips which are mounted between the fabric layers, parallel in the longitudinal or transverse direction of the curtain.
  • At least one layer of fabric is formed as an insulating layer.
  • the insulating layer has a higher insulating effect than the thermally expanding material.
  • the insulating layer comprises a nonwoven fabric.
  • the thermally expanding material is endothermic.
  • the thermally expanding material is designed in the form of slats which extend over the curtain and are arranged in particular in the chambers.
  • FIG. 1 schematically shows a fire retardant device according to the invention.
  • the fire-retardant closure 1 is provided in this case for the closure of a door opening 2, the closure 1 a Curtain 3 is attached to the top of a wall 4, which in turn limits the mentioned gate opening 2 at the top.
  • a curtain 3 is attached to the top of a wall 4, which in turn limits the mentioned gate opening 2 at the top.
  • guides 6 are attached, whereupon the curtain can slide in the event of a fire along.
  • curtain 3 can be used for the same type of opening 2 or passage in a wall 4 or a building.
  • the curtain 3 has a width that is at least equal to the width of the passage 2 to be closed, and a length in which it is rolled up or folded. In this way, the curtain 3 can be stored compactly above the opening 2 to be closed.
  • the curtain 3 comprises two layers of fabric 7, 8, which are made of fire-resistant material.
  • Such a layer of a curtain 3 may for example be made of a fiberglass cloth that can withstand a temperature of at least 500 ° C, depending on your needs you use a fiberglass cloth, which can withstand even temperatures of 600 ° C.
  • the two layers of fabric 7, 8 of the curtain 3 are connected to each other, so that internal chambers 9 are formed, and in FIG. 2 is reproduced.
  • These internal chambers 9 form compartments or tunnels 10.
  • the internal chambers 9 are designed as tunnels 10 which extend in the direction of the fire.
  • tunnels 10 are formed by cloth strips 11 which are placed between the two fabric layers 7, 8 and which are connected to the two layers 7, 8 by adhesive or the like and thus form partitions 12 separating the tunnels 10 from each other.
  • These strips 11 can be made of the same material as the fabric layers 7, 8, between which they form connections. But they can also be made of a different fire-resistant material.
  • the tunnels 10 are partially filled with a thermally expanding material 13, so that they are initially only partially filled and in case of fire or heating, the expansion of the expanding material is made possible. These tunnels ensure that the thermally expanding material stays in place and the curtain is held together.
  • the expanding material 13, such as slats 14, may be slid into the tunnels 10 along the side edges 15 of the curtain and extend mainly toward the surface of the curtain 3, in other words between the partitions 12 extend the curtain 3.
  • These slats 14 are made of a rigid material to give the curtain 3 a greater rigidity against curvature,
  • the height of these slats 14 is greater than the distance between the partitions 12 in the curtain 3, whereby the slats 14 and the partitions 12 overlap and the curtain 3 is less thick when rolled up and therefore the whole thing can be stowed more compact ,
  • the curtain is part of a fire retardant device 16, which is also provided with at least one, in this case, two cables 17.
  • FIG. 1 The operation of this fire retardant conclusion is out FIG. 1 visible and works as follows. Under normal circumstances, in other words, when it is not burning, the curtain 3 is rolled up at the top 5 of the opening 2.
  • the curtain 3 is rolled over the door opening 2, wherein this movement of the curtain 3 is guided by the guides 6.
  • the unwinding can either be triggered automatically, for example by activating a smoke detector, or it is executed manually.
  • the curtain and the expanding material 13 processed therein are subjected to an increase in temperature, whereby the expanding material 13, depending on the type of material, swells above a certain temperature.
  • the tunnels 10 are partially or completely filled with the expanding material 13, the material 13 expanding both in the thickness of the curtain 3 and in height, whereby an airtight and heat-resistant finish is produced, which promotes the propagation of flames and to prevent hot gases and also to prevent that an air flow is created, which could stoke the fire.
  • the curtain 3 Characterized in that the curtain 3 swells locally on the cable 17 to the top 5 of the opening 2, the curtain 3 is to clamp between the cable 17 and the wall 4, which closes the door opening 2 at the top 5. This prevents any flashover of flames and gases at this point.
  • the curtain 3 can additionally be provided on the underside with flaps which prevent hot gases from flowing through at the bottom of the passage 2 as well.
  • the strips 11 forming the dividing walls 12 may be made of a different refractory material than the two layers of fabric 7, 8 of the curtain 3.
