Definitions

  • the present invention relates to a device for sealing a gap in case of fire.
  • the present invention has for its object to provide a device for sealing a gap in case of fire, which is buildable in simple, but very effective.
  • the inventive solution consists in a flap which is movably supported by a hinge and fixed by means of one or more burnable or fusible threads, rods or the like in an open position so that the door can perform all necessary movements in normal operation, without them Flap to touch.
  • the temperatures rise very quickly, so that the thread or the threads either burn or melt, so that the flap falls by gravity into the closed fire position and effectively seals the gap.
  • the flap covers the entire width of the door and thus the entire gap. It is also possible to use a plurality of adjacent flaps with no or only a very small gap which is not relevant to fire protection, in each case between two adjacent flaps.
  • the flap itself preferably consists of a refractory and heat-insulating material, for example on the basis of calcium silicate or mineral wool, as used for example for fire-resistant insulating panels.
  • the hinge with which the flap is attached to the lintel must be smooth even at high temperatures. It can be made of metal, but for example also of one refractory and tear-resistant fabric, with or without additional insulating material.
  • the fabric hinge has the advantage that it can easily be adapted across the width even on odd surfaces, that it does not develop its own deformation and thus remains easy to handle under fire and that it seals well over the door width.
  • the hinge can also be made of double-layered fabric, wherein between the fabric layers a foaming in the event of fire and insulating material is used.
  • the thread or threads may consist of, for example, spun polymer yarn or polymer thread, for example of polyamide, polypropylene or polyester. But also natural fibers, such as cotton yarns, are possible. It is only important that the thread remains stable at room temperature for a long time, but quickly burns or melts in case of fire and so releases the flap.
  • more stable holding elements such as bars, can be used if the size or the weight of the flap require a higher force-absorbing capacity.
  • the thread melts or burns safely even when the fire breaks out on the other side than the marked side, it can be pulled through the very thin hole, which does not allow fire or heat through, to the other side of the fall and fastened there that he would then be exposed directly to the fire and shut the door.
  • it can be attached to the underside of the flap where the hot smoke of smoke passing through the gap would immediately destroy it and thus close the flap.
  • the thread can be looped to various positions on both sides of a gap, so that purely functional a safe release position is reached.
  • the length of the flap should be selected so that it closes the gap safely even if the door or door leaf is expected to move maximum.
  • the flap is preferably horizontal in the closed state, but it can also come to lie obliquely rising or falling depending on the space conditions of the geometry of the gap to be sealed.
  • a bar or one or more barbs are attached so that the movement is limited by positive locking when the door / door leaf comes to rest.
  • This flap can be used in a variety of types of fire protection shutters, such as rolling doors / gates, sectional doors, Staufelteltoren and sliding doors or gates, but also with textile blinds.
  • the invention is not limited to horizontal columns to be closed. If one forces the closure of the flap by mechanisms other than by gravity, for example by spring force or stored compressed air, the principle according to the invention can also be applied, for example, to vertical gaps.
  • Initial situation is a building construction 1, which has a fall 2 in the door opening area or gate opening area.
  • a door leaf 3 serves the closure of the opening as intended.
  • a gap 4 remains, in the exemplary embodiment shown a horizontal gap.
  • smoke, fire and the like can also extend through this gap to the other side of the door leaf.
  • a closure flap 5 is arranged by means of a hinge 6 in such a way that in the opened state according to FIG Fig. 1 Hanging on a thread 7, which is attached to a building-side attachment point 8.
  • the fire protection situation in accordance with Fig. 2 results in which the fire damper 5 is pivoted about the hinge 6 such that the horizontal gap 4 is closed.
  • FIG. 3 and 4 show the same on-site situation, but here is a roller door is arranged, which has a door shaft 10 a wound roll-up door 11.
  • the rolled up gate is much thicker than the unrolled shaft.
  • Fig. 3 and 4 show the special feature that the closure flap 12 which is pivotable about the hinge 13 is held by means of a thread 14 which is articulated on the one hand at a deflection point 15, which is arranged on the building side, and on the other hand at an attachment point 16 outside the door 11.
  • the thread 15 is guided through an opening 18 in the fall 2.
  • the thread can now melt or burn either in the region of the flap 12 at the designated 14 point or on the other side of the gate outside the fall at the point designated 17 and thus cause the falling and closing of the flap 12.
  • Fig. 5 shows a special feature in which the pivotable about the hinge 20 flap 21 has a projection 22. As a result, the movement of the door leaf 3 is limited in the area 23. This is advantageous when the gate expands, moves, and the like due to a fire.
