Definitions

  • the invention relates to a fire or smoke protection device for an opening in a building part, in particular a Torab gleich, with a flexible, flat fire protection element, which is folded into a bearing assembly in which the fire protection element in folding, and in a Abdichtab extract in which the Fire protection element is deployed and the opening closes, can be brought.
  • Such fire or smoke protection devices are used to close in the event of fire openings, such as gates, passageways or doors, fire and / or smoke-tight, to prevent a fire from spreading.
  • BEST ⁇ TSGISNGS OPIE which is guided in lateral guides and is lowered in case of fire in these guides to close the opening.
  • a disadvantage of this solution is that always guides must be present, which narrows the architect in his freedom of design. In addition, guides can pollute and must therefore be regularly checked and cleaned.
  • a fire and smoke barrier for rail vehicles which comprises a fire protection textile, which is arranged around an end wall passage of the rail vehicle.
  • the fire protection textile seals the passage from all sides.
  • a fire protection curtain is known from EP 1 964 593 A1, which has a perforated web in front of the fire protection textile, through which convection occurs in the event of fire.
  • the fire curtain always requires a winding shaft.
  • the invention has for its object to improve the fire protection effect and / or easier to build the fire or smoke protection device with the same fire or smoke protection.
  • the invention solves the problem by a generic fire or smoke protection device, wherein the fire protection element has a recess on at least one side, by means of which the building part is at least partially comprehensive for guiding the fire protection element.
  • An advantage of the invention is that it is simple. So it is simply necessary to attach the fire or smoke protection device above the opening to be closed in case of fire.
  • a fastening device is released automatically or manually, so that the fire protection element preferably falls down alone by gravity and thus closes the opening.
  • the fire protection element is guided by the indentation on the building part, for example a wall, so that pressure differences on both sides of the fire protection element do not cause it to be excessively deflected.
  • the fire or smoke protection device can be designed to be particularly flat, since the fire protection element can be stored folded.
  • a fire or smoke protection cover is understood in particular to mean any device which is designed to prevent or sustainably inhibit the spread of fires or to reduce the spread of smoke produced by a fire.
  • Such fire or smoke protection covers for example, must withstand at least 30 or 60 minutes fire and therefore differ fundamentally from devices that are only suitable for closing openings.

  • Such fire protection textiles belong to the prior art and are therefore no longer described.
  • An advantage of the use of fire protection textiles is the low production costs. It is thus possible for the fire protection element to consist of one, two, three or more flat fire protection textile pieces by means of sewing hen produce. Due to the simple construction, a fire protection element with fire protection textile is robust and less prone to failure. This leads to a safe functioning even after a long time of non-operation.
  • the fire protection element in the sealing arrangement runs downwardly at least in sections, conically. It is particularly favorable if the fire protection element in the sealing arrangement runs down completely conically. In this case, a space-saving bearing arrangement results since sections of the fire protection element located further down can be nested into sections of the fire protection element located further up.

  • the fire protection element is designed so that a predominant part of the energy necessary for closing comes from potential energy of the fire protection element itself. In this case, it is sufficient to solve a fastening device by means of which the fire protection element is held in the bearing assembly. Gravity driven, the fire protection element then moves into the sealing arrangement. Drives are expendable, so that the fire or smoke protection device is particularly robust and maintenance-proof.
  • the fire or smoke protection device comprises a bottom plate which is fixed to the bottom of the fire protection element.
