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 which at least for a certain time oppose a fire.
- These fire-resistant glazings are the subject of numerous relevant industrial property rights which are based on the principle of achieving fire protection by using 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 glass panels mounted 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 classes, a distinction is made between EL, EW and E glazing. By specifying their fire resistance time in minutes, they are additionally characterized (e.g., EW 30, El 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. In the case of El 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 El 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 in such a way that it combines the advantages of e-glazing with the radiation heat protection necessary for escape routes and refugee rooms.
- 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 found 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 kühiungs employmenter 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 water mist curtain placed in front of the fire-resistant glazing makes it possible with great advantage to classify the fire protection device into the next higher classification EW without having to accept the structural disadvantages of EW glazing.
- 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 distributing in case of fire, as described for example in DE 196 40 537 C2, and also shows sprinklers along a Glass facade are arranged.
- the sprinklers typically do not produce any 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.
- 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 34968 A1 discloses a fire door is known, are cooled in the door frame and profile by water, which is passed through appropriate cavities. In addition, the door panel can be sprayed with water from the outside. With these measures, discarding or warping the fire door should be prevented in case of fire.
- a fireproof glazing 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 fire 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 have become known, for example, from DE 197 10 289 C1.
- alumino-silicate glasses in particular by the LAS-G lassystem (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 e.g. became known through EP 0 056 677 A1.
- Fig. 1 in a longitudinal section through a building tract a
- a high-pressure water misting system for generating Fig. 2 is a frontal view of the glass partition wall and its associated high-pressure water misting system according to a water mist curtain in front of the glass partition wall is assigned, in the standby state
- FIG. 4 is the frontal view of FIG. 2 also in case of fire,
- FIG. 5 in a longitudinal sectional view corresponding to FIG. 1, a second embodiment of the invention
- Fig. 6 is a front view of the fire protection device of FIG.
- FIG. 7 the second embodiment of the fire protection device of FIG. 5 in case of fire
- Fig. 8 the frontal view of FIG. 6 also in case of fire.
- Figures 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 with a fire remote 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, in 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, sealing and mounting 3. It is shown in cross section in FIGS. 1 and 3 and in a front view in FIGS. 2 and 4.
- monolithic glass sheet is intended to indicate that a continuous one-piece glass sheet, i.e., not a laminated glass, is used in each case.
- 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 water supplied 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 above the glass partition by a fire protection panel 8 divided, 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 of the water via special micro-nozzles in the nozzle head, with which the spray pattern (Spray angle), the Dürrhne and the drop spectrum set
- the atomization is preferably carried out in the form that 90% of the atomized water is contained in drops ⁇ 200 microns.
- 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.
- Parallel to the door element, which has a width of approx. 3 m, the nozzles 2 of the high-pressure water mist system are installed at a distance of approx. 80 cm with their supply line directly on the floor slab.
- the structure and operation of the fire protection device to that given in Figures 1 to 4 applies accordingly.
- the high-pressure water misting system is mounted with their nozzles 2 on the side facing away from fire of the respective fire-resistant glazing.
- the high-pressure Wasservemebelungsstrom 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.
