Definitions

  • the invention relates to a mobile smoke and fire protection device in buildings and a method for preventing smoke and fire propagation in structures.
  • the fire brigade In a fire, the fire brigade generally uses the staircase as a route of attack.
  • the door in particular an apartment door, behind which the fire is located, is opened by the fire department. After entering the burning room, the entrance door must remain open a gap at least due to the hose of the fire department. The same applies if more people enter or leave the scene. In this case, the door has to be opened even further.
  • the opening of a door, behind which the fire is located and also the at least partially forced keeping open the door leads in most cases to a spread of smoke and thus to a threat to people by the smoke and to increase the fire damage.
  • overpressure ventilation by means of powerful fans. These are intended to generate a relative overpressure and force an airflow, which reduces further smoke entry into a stairwell. In practice, however, shows that this pressure ventilation can not always be carried out successfully.
  • larger buildings and also in public buildings are often structural requirements to prevent the spread of smoke and fire legally required, such as fire doors, but if you have to go through the fire doors and, for example, equipment and extinguishing hoses must be performed, their operation become obsolete, as in this case the fire or smoke protection door often can not be closed.
  • a disadvantage of this fire door is that it must be present in a building in a correspondingly high number.
  • the on-demand access port for small animals, such as cats is a weak point in the event of burglary and weakens the mechanical stability of a door leaf.
  • the protective device has vertical supports and on the top of a pull-out cross member for adaptation to the opening to be closed.
  • the previously known protection device is provided as a preventive measure for danger spots and relatively heavy in weight and cumbersome to assemble.
  • the present invention is therefore an object of the invention to provide a mobile smoke and fire protection device with which the fire department in a fire openings in one However, if necessary, the openings should allow access for persons fighting the fire and / or for the implementation of fire-fighting equipment without appreciable passage of smoke.
  • Doors especially apartment doors, which are arranged to a staircase or staircase, open in general to the inside.
  • the protective device according to the invention can be fitted in front of the door to be opened in the opening, for example in the door frame, whereby a "smoke seal" is at least in the upper region of the opening. Only then the front door is opened, which can be approached by the passage opening and / or the passage opening in the sealing unit, which is adapted in shape and size to the opening in the building, fire or equipment, firefighting equipment, such as a fire hose , can be brought to the blaze. Subsequently, the passage opening and / or the passage opening can again be largely closed.
  • the protective device according to the invention can be used immediately after opening the door. In this case, which will rarely happen, Smoke propagation can be checked again shortly after installation.
  • Another advantage is that the rescue squad can be available for the attack team used immediately before the burning room behind the protective device according to the invention. In this way, longer distances are avoided and faster firefighting is possible.
  • Another advantage is that an attack party is already after leaving the fire after the protection device according to the invention in a largely secure area.
  • a fabric or a film which is resistant to high temperatures and resistant to the effects of flame.
  • the sealing unit is at least partially variable in size.
  • the sealing unit is provided with a clamping or clamping frame, which is provided with adjustable frame members.
  • adjustable frame members can, for example be provided telescopic frame members which adapt both in height and in width, the sealing unit to the opening to be closed.
  • the sealing unit is formed of two- or multi-part sealing elements.
  • the sealing unit can be adjusted even more optimal. So you can, for example, in the upper part of the sealing provided with a clamping frame and achieve a secure seal, while at the bottom of a sealing element is provided which is flexible and is provided for a through hole and / or passage opening or formed accordingly.
  • the lower sealing element may be formed as a kind of curtain.
  • the tenter frame By making the tenter frame extendable towards the lower area, an even better seal is achieved.
  • the passage opening or the passage opening can be correspondingly reduced when not in use or even completely closed.
  • the protective device after completion of the use ie after extinguishment of the fire, can remain in the opening, being provided with sealing elements, such as adhesive or adhesive tape.
  • sealing elements such as adhesive or adhesive tape.
  • an at least largely smoke-tight closure can be achieved. If then there is a possibility that smoke and smell can be removed, for example through a window, then the protective device according to the invention can remain for several days and it is avoided that fire odor spreads throughout the house or is not removable.
  • the protective device according to the invention can be in addition to considerable health damage and prevent very large property damage.
  • the overpressure ventilation works very poorly due to the usually high leakage rate of the large airspace and on the other hand occur here by smoke spread in a large area enormous damage from smoke.
  • the protective device according to the invention physically uses the thermals which arise during a fire in a room, the so-called "chimney effect".
  • the supply air opening in the lower area can be adjusted in a controlled manner by means of the protective device according to the invention. This results in an air flow from the area which is to be kept smoke-free (usually the stairwell) in the area affected by the fire and an outflow of smoke from the exhaust air opening in the upper area of the fire area.
  • the protective device according to the invention can therefore smoke without overpressure fans prevent due to this physical principle. If the protective device according to the invention is supplemented by the use of overpressure fans, the effect of the forced air flow can be increased by better controlling the air flow in the building.
  • Fig. 1 shows a schematically simplified floor plan of a building opening 11 with a smoke and fire protection device 13 according to the invention, which is hereinafter referred to simply as "protection device” for simplicity, when mounted in a wall plane 10.
  • the protection device 13 is provided with a sealing unit explained in more detail below. If a door leaf 12 strikes in the direction of attack of the preceding emergency forces, the protective device 13 in the wall level 10 (primarily within the door frame) can already be mounted before opening the door. Often, this accessible area is about as wide as the wall thickness in which the door is built. In this case, the smoke trap can easily be clamped in the accessible area of the door frame.

When not in use, the sealing unit 16 can be sealed again with the two side parts 17.
  • the sealing unit 16 may optionally also be connected via the flexible side parts 17 fixedly connected to the side sill bodies 15.
  • the mounting of the protection device 13 in or in front of a building opening 11 can also be done mechanically, for example by attachment with nails, screws or the like.
  • a magnetic attachment for example with a strip magnet, which is arranged on the sealing unit 16, possible if a metallic door frame is present.
  • the protective device according to the invention has found input in firefighting and, for example, each or almost every fire brigade is equipped with it, a further relief can be achieved if, when planning and building a building with doors, especially fire doors, a circumferential groove or recesses , Holes, fasteners and the like are provided in the door frame or the door frame or in a wall part adjacent to the door. In case of fire then this groove for Receiving guide parts of the sealing unit 16 serve to anchor it to the door frame.
  • FIGS. 7 and 8 a variant embodiment is shown, wherein the sealing unit 16 can be closed with a zipper 20.
