    The present invention relates to a fire protection device, in particular a wall and ceiling bulkhead.
    From the prior art, a variety of fire protection devices for pipes, especially ventilation pipes, known. As closure devices while fire dampers are used and as a triggering device is usually a spring mechanism or a servomotor that moves the fire damper in case of fire after their immediate release by means of a retaining device extremely quickly in its closing pitch, in which this one- or multi-part flap closes the cross section of the pipeline.
    As a retaining device that holds the fire damper in its open position at ambient temperature, for example, a fusible link can be used. In any case, it is important for the retention device to release the closure device even at a relatively low elevated temperature, because it is desirable to achieve the earliest possible closure of the pipeline against the spread of the fire and the fire flue gases. Hazardous flue gases occur in case of fire at much lower temperatures than those exhibited by the spreading fire itself.
    It has also been known for a long time to use intumescent foams for sealing a pipeline in the event of a fire, which foam at elevated temperature with a high volumetric expansion while securely closing the pipeline endangered by fire penetration. The disadvantage is that it has previously required a large amount of fire protection compound for the closure of pipes with a larger diameter.
    Only as one of the examples, the fire damper device according to AT 508116 B called.
    The requirements which are set according to the new EU standards on fire damper devices can, as has been shown in practice, the previously known fire protection in some cases not fully meet. There are so far no separate installations in the fire dampers, which ensure with great certainty that, especially at the beginning of a fire, the fire damper is already closed, but the same can not always ensure sufficiently at this early stage that the smoke despite in the wake of the first heat already closed plate, but just before the fire protection compound fully foams, yet penetrates through the superimposed sealing levels of Klappenbiatt and Klappblatt-Anschiag. 2/21 2
    In addition, it has proven to be very important to ensure that there is no transmission of heat from the fire from one affected pipeline to the housing of the fire damper and from there to the piping passing from there. This is particularly crucial if the Kiappengehäuse, as is common today in most cases, made of a metal, in particular steel sheet, which in particular from the side of the shaping, the possibility of subsequent installations and the like. is much more flexible to handle, than the previously known valve housing made of refractory material, such as. from Ridurit.
    It is therefore, in particular in fire damper housings made of metal of great importance, for a separation of the high thermal conductivity materials - mostly metal - the pipes and the fire protection housing by means of interposition of a fire and refractory temperature decoupling material care.
    In order to address the above-mentioned problem of leakage of fire dampers against fire smoke breakthrough, the subject of the invention is a novel fire protection device, in particular a ceiling or wall bulkhead, for pipes, preferably Lüftungsrohrieitungen, in buildings, which through openings in separating elements thereof from the group walls and ceilings passed through and equipped with a one, optionally two- or multi-part, damper blade with a coating of intumescent fireproof fire protection compound comprehensive fire damper in a damper housing with at least two openings for the connection of the pipes, which is characterized - that, if necessary multi-part, valve body with a fire-resistant material, preferably with steel (sheet metal) is formed, and - that either the steel made and by means of flap closing mechanism in Brandfali, if necessary, automatically closing end Klappengrundpiatte at least one, in particular their fire events facing, with the Kiappenanschlag or with the sealing plane of the housing sealingly cooperating closing side and / or the Kiappenanschlag with a completely covering the flap leaf or substantially ring-shaped and in any case to the outer edge of the flap base plate and / or up to the inner edge of the flap stop or the sealing plane of the valve body layer, in particular film or membrane, from a - the sealing effect of the Ktappenbiatts, especially those of the Klappengrundpiatte, against the penetration of smoke in the Kiappenanschlag or at the sealing level under the pressure of the closing mechanism pressed closed position substantially increasing, surface shape-adaptive 3/21 3 (high) temperature-resistant Polymermateriai, in particular silicone, polyfluoroalkylene or ethylene-propylene-diene rubber (EPDM) material coated.
    On the Anschiagsseite the Klappenbiattes or individual Klappenteiibläüüer in the case of two- or multi-part fire dampers and that, especially on the attack side of their e.g. Made of steel fabricated flap base plate coating arranged with the fire-resistant Polymermateriai, this is now a full-surface coating or only a full coating of the (outer) edge zones of the flap base plate, which basically either rectangular, square or circular shape may have, where the polymer support in Closing division of the fire damper rests on the attacks and / or the coating of the attacks or the sealing levels of the fire enclosure bring / brings the advantage of a topographic and therefore actually gas and smoke penetration tight adaptation of the bonded to the flap base polymer seal to the stop surfaces or sealing levels of fire protection housing. For certain embodiments of fire dampers a compelling full area or edge zone occupancy of both sides of the fire protection base plate is advantageous. In this case, it is thus provided that the flap base plate is covered on both sides directly with the entire surface or ring-at least up to its outer edge-covering layer, in particular foil or membrane, from the (high) temperature-resistant polymer material. In fact, this may also be advantageous for a one-piece fire damper, if it has a pivot axis which is perpendicular to the housing axis and in the housing e.g. centered, with one half of this flip-flop corresponding to " Haibanschlag " when closing at a unidirectional one-half of the total stroke. strikes and there by means of the refractory polymer layer actually smoke-sealing acts and the other half of this turning flap sealingly against the facing in the opposite direction half stop, which is to be pointed as a precaution to the Fig, 1c.
    Furthermore, it has proved to be favorable, in particular, for achieving a uniform expansion of the fire protection compound foaming in the fire protection case, if the (individual) flap base plate of the flap plate on one of its two sets, and in any case on a completely or at least ring-like covering to the outer edge, in particular film or membrane, from the (high) temperaturiesten Polymermateriai and at least on their attack side one with a, preferably with steel! formed, holding plate closed to the outside, layer of or with the intumescent fire protection compound. 4/21 4
    In order to achieve a further increased fire safety, it can be important and advantageous to ensure heat insulation also within fire protection compound.
    Accordingly, it is favorable to provide that the layer with the intumescent fire protection compound with a total of three layers, with two layers of fire protection compound and at least one disposed therebetween layer or plate of a fire and refractory Entkoppiungs- or Isoiiermateriai on an inorganic-mineral basis , such as Ridurit, is educated.
    This measure has the advantage of a kind of temporally two-stage volume expansion of the fire protection compound, wherein the fire happening nearer arranged mass expands very quickly towards the fire and ensures sealing and the " behind " mass arranged isoiiermateriai, only delayed to begin to expand and ultimately, e.g. possibly remaining open areas in the housing cross-section fully filled with fire protection compound.
    As regards the control of the increase in volume of the fire protection compound in case of fire, it has proved to be particularly advantageous if - for a Klappenbiatt or with their flap base plate substantially congruent, valve leaf or housing extension or expansion of the intumescent fireproof mass layer in Brandfaü - this layer outwardly final holding plate, and optionally present in this layer insulating material with at least one bound to the respective flap base plate of the valve blade and aufkiappenden when expanding the fire protection layer layer, and possibly bursting fire, punched out and in case a substantially circular damper blade is formed with a plurality of such radially arranged elongated punched out.
    For the sake of safety in the event of a fire, it will continue to be mandatory in the sense of the new EU standards that the transmission of heat from a fire within a pipe run and, in particular, from the pipeline via the fire damper housing installed in the same to a further pipeline be prevented as effectively as possible should.
    Accordingly, it is further very particularly preferred in the context of the present invention to ensure that - in the case of a metal housing, in particular with (steel) sheet metal, manufactured flap housing - the same is formed with two housing parts, each of which from the other housing part through at least one decoupling component, if appropriate bound to a separating element of a building, in particular 5/21 5
    Decoupling, or od. Dgi., Is separated from a fire-resistant mineral-based insulating material.
    Here, it is further favorable if the valve body itself from a fireproof mineral-based, the metaiiischen connecting piece for the pipes from each other thermally separating T emperatur Entkoppiungs-, in particular Isoiiermateriai is formed.
    Furthermore, it can be provided that, taking into account the insulating effect against heat transfer described above, it is provided that the valve housing is made of steel and as such is designed as a fire protection slide-in unit which can be introduced into a respective pipeline to be sealed off.
    According to a further variant of the invention it can be provided that the Kiappengehäuse is mainly made of steel (biech), but that it is anchored on one side in a Klappengehäuse Wandungsteii of fire-resistant, mineral-based decoupling, in particular Isolierplattenmateriai, softer also the stop or the sealing plane for the closing or stop side with the layer, in particular film or membrane, from the (high) temperature-resistant Poiymermateriai covered cap base plate of Kiappenblatts forms.
    Last but not least, it should be noted that the flap housing in addition to the two mutually identical axes having openings for the connections to supply and discharge pipes one, for example, equipped with a cover or screw cap, revision opening, and / or that it with at least one other in particular lateral opening for the connection of at least one further pipeline is formed as an angle, T-shaped or Verteiier housing.
    Reference to the drawing, the invention is explained in more detail:
    1a and 1b show a sectional view of two Ausführungsfonmen of the invention used according to the new fire protection Kiappenblatts, the sketch of Fig. 1c a mögfiche arrangement of fireproof Poiymerbelegung on both sides of a fire protection turning cap, the Fig. 2 a "mixed" according to the invention. FIG. 3 shows a two-part flap housing 10 according to the invention, FIG. 4 shows a fire protection flap housing itself made of the temperature decoupling material as a ceiling bulkhead, FIG. 5 shows the basic design of a split fire damper FIG. 6 shows an overflow opening in a solid wall in accordance with the invention, FIG. 7 shows a detail of a steel casing and FIGS. 8a to 8d show special embodiments of the parts of fire protection cupboards , 6/21 6
    The fire damper 2 shown in FIGS. 1 a and 1 b in blocking division, which provides for substantially improved tightness, comprises a fire damper 2 arranged in a steel fire damper housing 10, of which only one wall is shown here, whose damper base plate 20 is connected to a hinge 3 at the said housing wall is angeienkt. At its the stop 15 and the sealing plane of the housing, and usually also the side of the fire hazard B side facing the flap base plate 20 is a film or a coating 21 of a slightly conformable form adaptable, and in any case heat-resistant polymer material surface connected , which here eg the circular or square shape of the fire damper 2 or adapted from the Kiappengrundplatte 20, conveniently has the same surface shape as the same and cheaper way to their outer edge 205 ranges.
    This polymer layer 21 can be formed, for example, from a silicone polymer, it lies in the closed position S of the flap 2 with its edge zones all around on, for example, as the flap base plate 20 circular or square or rectangular, closed annular stop 15.
    Particularly high is the sealing effect, if also on the stop surface of the stopper 15 as described above, a heat-resistant polymer layer, in the Fig. 1a indicated by a just limited, hatching direction having another direction, with the symbol 210, is applied.
    Not least, it should be mentioned that, of course, only the Kiappengrundplatte 20 may be provided without said polymer layer 21 and therefore only the abutment surfaces of the stopper 15 are coated with the high-density heat-resistant polymer.
    From Fig. 1b is further seen that on the heat-resistant polymer layer 21, at least when it is applied over the entire surface of the Kiappengrundplatte 20, against the fire hazard side B through a layer 22 of the intumescent in the event of fire intumescent material follows, which finally to the outside is usually completed with a made of steel Haltepiatte 24.
    At 30 the Ausiösehaken, for example, with a fuse called, which dissolve at elevated temperature in case of fire from each other and so release the federbeschäftete damper blade 2 for folding in the Schiießstellung S, and 3 with the Schwenkgeienk the damper blade. 2
    The damper blade 2 shown in FIG. 1b differs from that shown in FIG. 1a in that here the fire protection mass layer 22 is constructed in three parts, with a layer 23 7/21 7 of an inorganic, heat-resistant between the two fire protection mass partial layers 221, 222 Material, for example, gypsum fiber (Ridurit) is arranged
    The sketch of Fig. 1c shows only schematically a one-piece fire damper 2, which of course releasably spring loaded, a pivotable in the fire damper housing 10 shaft 25 is pivotally and in the case of mutually oppositely oriented half stops 15, 15 'strikes and thus seals against fire breakthroughs.
    Here, therefore, at least one of the halves of their flap base plate 20 on one side and at least the other half on the other side of the flap base plate 20 with the heat-resistant, seal-improving, heat-resistant polymer, e.g. Silicone 21, coated.
    With otherwise constant reference numerals, Fig. 2 shows a fire blanket ceiling 100 with a fire damper housing 10, for example made of steel, which is anchored on the underside in a temperature Entkoppelungsunterteii 4 of an inorganic heat-resistant and especially non-heat conductive material such as Ridurit, the in turn, as indicated there schematically, by means of fastening elements 45, for example screws, to a double plasterboard ceiling 9 'od. dgi. is bound. In the wall bushing 90 then reaches the risk of fire side B pipe socket 6 'with lip seal 71 through which the pipe 7 is slipped or pushed a pipe guide.
    Here, the Entkoppeiungsbauteii 4 of the fire enclosure 10 itself forms the stop 15 for the Kiappenblatt 2 in particular for the flap base plate 20 with the new heat-resistant, the tightness of the entire fire damper 2 on the one hand against air passage and on the other hand against breakthrough of smoke and fumes significantly increasing heat-resistant polymer layer 21. Shown here is, as again closed by holding plate 24 to the outside, by the heat of a fire B, the fire protection poiymermasse 22 is just in the stage of inflation to the fire B out.
    Also indicated here is still one of the fire protection layer 22 penetrating distance securing spring elements 8, which are each formed by corresponding punched holes of the holding plate 24, are attached with their free ends to the flap base plate 20 and ensure that the holding plate 24 during the inflation of the fire protection layer 22 in is moved substantially in parallel position to Klappegrundpiatte 20, whereby volumetric irregularities during foaming are largely avoided. 8/21 8
    The steel housing 10 here has a parallel to the ceiling 9 'aligned spigot opening 16', which is completed here by means of detachable lid 17, for example, to perform inspection or Reinigungsarbeiien. To this opening 16 'can, in the same way as in the further, upward connection opening 16, a e.g. sealed by means of lip seal 71
    Continuing pipe 7 to be connected. 6, the Anschiussstutzen for the tubes 7 are designated.
    In the basically the same construction, e.g. 3 is the left part 12 of the same formed with steel and is also formed as a pipe connection piece and forms even here integral with this steel housing part 12 stop 15 on the one hand and on the other hand is after outwardly facing short flange 101 between two heat-insulating, mineral temperature decoupling parts 4, 4 'arranged. The continuing, also formed with steel housing part 11 is formed with a here both temperature-decoupling components 4, 4 'cross-flange 102, but between the above-mentioned "short". Flange 101 and the overlapping flange 102, a temperature transition-inhibiting distance a is maintained.
    As far as the flap panel 2 of this fire damper housing 10 is concerned, the same is divided into two flap openings, each of which has the smoke-proof coating or coating 21 with the heat-resistant polymer on the closing compartment which folds up against the source of fire B and otherwise in a completely analogous manner the fire protection flaps 2 described above is built.
    Fig. 4 shows - with otherwise identical reference numerals - a equipped with an inventively designed fire damper 2
    Fire damper housing 10 which, since it has e.g. is formed of gypsum fiber boards, even the heat dissipation preventing any Temperaturentkoppefungsteil - with otherwise similar features as the other fire dampers - forms.
    Fig. 5 shows - with otherwise constant reference numerals - a directly in the means of insulating material 40 in the aperture opening 90 of a double plasterboard wall 9 arranged tube 7 housed insert fire damper housing 10, also with a two-piece Klappebiatt 2, each of the two Teilbiätter the same structure with KiappengrundpSatte, heat-resistant polymer layer, fire protection layer and Haiteplatte has, however, the triggering of the closure of the two flap parts by means of servomotor M, which -isoliert of the other steel parts - on a ring-like thermo-decoupling component 4 " is arranged on the one hand, the insertion part E of the fire protection housing 10 and 9/21 9 fully temperaturisoliert arranged by the same of the connecting piece 6 for a continuing pipe.
    Fig. 6 shows - with otherwise constant reference numerals - the arrangement of a fire damper 100 according to the invention in an overflow opening with pipe 7 in a building wall, wherein the fire damper 100 is basically formed in the same way as the previous Fig. Show, only that whose terminal 6 no continuation pipe is connected, but that its opening is equipped with a shutter 81, and that on its left side a cold smoke barrier 80 is arranged with a flexible, aufgepffapptung in Offenstefung Kiappeblatt 82 with adjustable magnet, to the left then follow two example formed with a foam, mutually staggered Schaildämmelemente 83 and finally on the left wall side of the pipe opening opaque grille insert 84th
    Fig. 7 shows - with otherwise constant reference numerals - the essential part of a made of steel fire protection cap housing 10 with a likewise closable by means of servomotor M or solenoid with linkage in case of fire two-leaf fire damper 2 in section with the base plate 20, the support plate 24, the polymer coating 21 and the intumescent layer 22, wherein also here the flap stop 15 is made in one piece with the housing 10 made of steel.
    Finally, FIGS. 8a to 8d show the individual layers 21, 23 and 24 of the new fire damper blades 2 according to the invention, which are significantly improved in terms of their reference numerals.
    The holding plate 24 made of steel has several, in the case of circular damper blades radial, punched-86 ', which the - not shown here -
    Fire protection mass layer 22 and there are additional inorganic, heat-resistant heat propagation delay refractory layer 21 penetrating guide elements 86 form, soft with their free ends 87 on the - also not shown - flap base plate 20 are attached. For example only, a square flap base plate 21 is shown with its attachment points for the free ends of the guide elements.
    As the fire barrier layer 22 inflates, the connection formed by the guide elements 86 to the flap base plate 20 is maintained, only " extend " The guide elements 86 are now "unfolded" as a result of the biopressure of the fire protection compound. be, as can be seen also from Fig. 2.
    In this case, essentially the parallelism of flap base plate 20 and retaining plate 24 is maintained during the expansion of the mass of the fire protection mass and there is no deflection of the fire protection mass layer to be bonded, as a result of which a fire breakthrough through a building partition wall breakthrough opening is prevented perfectly.
    The insulating plate 23 is formed in the same way with punched holes as the holding plate 24. 11/21
