Definitions

  • the invention relates to a fire protection device to ensure a translucent, fire-resistant Kunststoffab gleiches in a building.
  • the statutory fire protection regulations require fire protection barriers.
  • glazings e.g. As door or window glazing, they must also comply with the fire protection regulations.
  • fire-resistant glazings that resist fire for at least some time.
  • These fire-resistant glazings are the subject of numerous, relevant protective legal writings, eg EP 1 255 021 A1 that are based on the principle of achieving fire protection by the use of particularly heat-resistant transparent fire-resistant panes, for example of glass-ceramic or tempered glass and given arrangements or holders.
  • the term fire-resistant glazings therefore components and Systems understood that consist of one or more translucent Glasinfeldem, which are installed with brackets and seals in a frame.
  • Fire-resistant glazing does not all have the same fire resistance. This is matched to the application and expressed in the relevant provisions by the so-called fire resistance class. With regard to their fire resistance ski, EI, EW and E glazing are distinguished. By specifying their fire resistance time in minutes, they are additionally characterized (e.g., EW 30, EI 90, E 30). E-glazings prevent only the spread of fire and smoke for the appropriate time. EW glazing must also prevent the passage of heat radiation. For EI glazing, moreover, it is required that the increase in the glass surface temperature on the side facing away from the fire does not exceed a certain level.
  • EW and EI glazings reduce this heat radiation, but their production is complex and costly.
  • the glazings are thicker, less transparent and subject to aging and stability problems.
  • the maximum disc dimensions are limited production and functional.
  • toxic fumes also form in the event of fire.
  • the invention has the object of providing the initially described fire protection device so that it combines the advantages of e-glazing with the radiation heat protection necessary for escape routes and escape dreams.
  • the invention is based on the recognition that the cooling and radiation absorption in the fire-remote space, ie the necessary radiation heat protection can be done by finely divided water droplets, if it succeeds to form a permanent curtain of water in front of the fire area facing away from the fire protection glazing. Since contact of cold water particles with the hot glass pane of the fire-resistant glazing can not be avoided, the resulting strong temperature gradient in the glass usually leads to breakage of the glass of the fire-resistant glazing and thus to loss lead the fire room closure. Surprisingly, however, it has been shown that when using in particular monolithic glasses for fire-resistant glazing in combination with a veil of finest water mist according to the invention, no cooling-related breakage of the fire-resistant glazing occurs.
  • the device according to the invention thus has the central advantage that in case of fire, a heat-binding water mist fog can be placed directly in front of the fire-resistant glazing without the glazing breaking. Furthermore, the advantage is achieved that toxic flue gases are washed out and cooling of the fire-resistant glazing occurs. Humans can thus not be damaged due to the water mist according to the invention, escape routes are thereby kept free.
  • the fire protection device according to the invention is not to be compared with a sprinkler system, which disperses water in a room in a large volume distributed in the event of fire, as it eg in the DE 196 40 537 C2 and also shows sprinklers arranged along a glass facade.
  • the sprinklers typically do not produce water mist, of which the fire safety regulations speak only when the water droplet size is ⁇ 1000 microns.
  • an additional transparent, curtain-like fire barrier made of the finest fog droplets in front of the fireproof glazing in case of fire in a relatively narrow space.
  • DE 101 45 136 A1 is an arrangement for foreclosure of fire and smoke in structures of the railway system, such as in a tunnel, known, the two arranged at a predetermined distance from each other, the protected space profile adapted spray elbows, which water is supplied steadily and under increased pressure and create a water mist curtain over the room profile.
  • this fire barrier requires that no fire doors and gates, and thus also fire-resistant glazing, be used; the water curtain should replace it as intended.
  • a comparable fire barrier with a water mist curtain also shows the abstract JP 2003/111 858 A1 , wherein the water droplets of the mist should have a mean size of 40 to 400 microns.
  • DE 32 34 968 A1 is a fire door has become known, in the door frame and profile are cooled by water, which is passed through appropriate cavities. In addition, the door panel can be sprayed with water from the outside. Such a system also shows the DE 31 06 110 A1 , With these measures, discarding or warping the fire door should be prevented in case of fire.
  • a fire-resistant glazing made of monolithic glass panes, in particular of thermally toughened borosilicate glass, is selected for the fire protection device, which is also wetted and covered by a high-pressure water mist in case of fire.
  • the heat radiation of the edge area is bound by the veil-like water mist with great advantage;
  • toxic fumes are washed out.
  • the simultaneous cooling achieves a high fire resistance duration of the fire-resistant glazing.
  • prestressed soda lime silicate glasses can be used.
  • Prestressed monolithic fire-resistant glasses are eg by the DE 197 10 289 C1 known.
  • alumino-silicate glasses in particular by the LAS glass system (lithium aluminum silicate), or glass ceramics are used.
  • both pure glass partitions and their combinations can be carried out with doors.
  • a preferred embodiment of the invention is characterized in that a glazed door with skylight and side part connects to a glass partition wall.
  • Such glass partitions are eg by the EP 0 056 677 A1 known.
  • FIGS. 1 to 4 show a first embodiment of the device according to the invention in a floor of an office building with suspended ceiling 6, with an office wing, the fire room 5 and a fire-facing space 4, which serves as an escape and rescue route. Both rooms are separated by a fire-resistant glazing E 60 in the form of a static non-supporting glass partition, which protects the fire-remote space 4.
  • This glass partition is formed, for example, nine parts in a three-meter frame element.
  • the fire-resistant glazing consists of a variety of monolithic glass panes 1 made of borosilicate glass with associated Framing, seal and bracket 3. It is in the FIGS. 1 and 3 in cross-section and in the Figures 2 and 4 shown in a front view.
  • monolithic glass sheet is intended to express that each one continuous integral glass sheet, i. no laminated glass is used.
  • the inventive device nozzles 2 for atomizing water to a water mist or mist 7, which are part of a high-pressure water misting system, in the space above the suspended ceiling 6 with the entire supply lines, control systems and release mechanisms is integrated.
  • These supplied water to a high-pressure water mist atomizing (or atomizing) nozzles 2 are parallel to the glass partition at a distance "A" such as 80 cm to 1 m, strip-shaped attached to the suspended false ceiling 6.
  • the false ceiling 6 is divided above the glass partition by a fire protection panel 8, which serves as a top panel for foreclosure of the fire-remote space 4.
  • the nozzles 2 are formed by special high-pressure water mist nozzles with a defined volume flow.
  • the nozzle distance within the bar is about one meter, which corresponds to one nozzle per meter of partition wall.
  • the operating pressure is provided by pump systems at a height such that a minimum pressure of 100 bar is present at the nozzle which is the most unfavorable for printing.
  • the water is sprayed at pressures of 10 to 200 bar to produce the water fog.
  • the atomization is preferably carried out in the form that 90% of the atomized water is contained in drops ⁇ 200 microns.
  • FIGS. 5 to 8 a second embodiment of the fire protection device according to the invention is shown, the identical in terms of construction (with the exception of the suspended false floor 6) with that according to the first embodiment, but as a fire-resistant glazing E 60 no glass partition, but a two-leaf door with steel frame 3 and skylight, both of which each have disks 1 made of a monolithic glass.
  • This fire-resistant glazing primarily protects, as in the first case, the fire-remote space 4, which serves as an escape and rescue route.
  • the fire protection device to the FIGS. 1 to 4 said accordingly.
  • the high-pressure water misting system with its nozzles 2 is mounted on the side facing away from the fire of the respective fire-resistant glazing.
  • the high-pressure water misting system is mounted on the fire-facing side or on both sides of the fire-resistant glazing.
  • a system consisting of a fire-resistant glass with monolithic glass panes and a device for atomizing water to water mist, which grants an additional transparent fire protection barrier in case of fire, heat and flue gases retains fire and thus exposed escape routes from dangerous heat radiation and protects against toxic smoke.
  • the system of the invention can be used in a variety of applications, eg for interior glazing, doors and foreclosures.
