Definitions
- the invention relates to a multi-chamber hollow profile for fire protection doors or windows with an outer hollow profile and an inner hollow profile, the outer hollow profile and the inner hollow profile being connected by means of at least two connecting webs which form at least one further hollow chamber and the further / n hollow chamber / s with are filled with a filling material and a method and an apparatus for producing such a multi-chamber hollow profile.
- a generic multi-chamber hollow profile is from the EP 0 802 300 A2 known.
- There is a framework of metal profiles in fire protection designs for windows, doors, facades or glass roofs is described.
- This known framework consists of an inner and an outer metal profile, each of which forms a hollow chamber profile. These two profiles are connected to each other via metal connecting bars, so that another hollow chamber is created.
- the cavities are filled with energy-consuming and crystal water-releasing moldings which have to be introduced into the cavities as plates, rods or the like.
- the EP 2 199 519 A1 and DE 34 38 861 A1 describe well-known multi-chamber hollow profiles with a similar topic. This is about hollow profiles that are connected by a thermal separation. At the same time, these hollow profiles form a further hollow chamber with the thermal separation. The thermal break is quickly destroyed in the event of a fire due to the materials used. This is particularly the case in DE 10 2005 059 633 B3 the approach is to permanently connect two hollow sections with additional mechanical connecting elements. For this purpose, a corresponding profiling of the hollow profiles suggested.
- all of the variants described have the disadvantage that they contain additional connecting elements, which can be a hindrance when machining the profile, and that they depend on the dimensions of the multi-chamber hollow profiles in terms of face width and structural depth. This inevitably leads to a high variant of the connecting elements and their area of application.
- Fire protection doors have been used in outdoor applications for a number of years. The reason for this is the increasing density of installation space in cities. Buildings are moving closer together and a fire spreading from one building to another or to other parts of the building must be prevented. Due to this growing area of application for fire protection doors and windows, new performance requirements such as wind and driving rain protection as well as thermal protection also come up to the multi-chamber hollow profiles used.
- the energetic heat protection differs significantly from the fire protection technology. While as little thermal energy as possible is to be lost through the door in the case of energetic heat protection, as much energy as possible through the door or its components is to be used in fire protection in order to withstand a fire for as long as possible. With thermally separated profiles in Fire protection is minimal, as in the case of the EP 0 802 300 A2 described multi-chamber hollow profiles.
- a material with fire protection properties in this case asbestos cement, with an appropriate strength can be used.
- the first variant has the disadvantages described above and the second the disadvantage of the materials chosen, which generally have a very high density for the load-bearing capacity / strength with very poor thermal insulation.
- the object on which the invention is based is to develop a fire protection profile system which consists of hollow profiles which are connected to one another by a thermal separation.
- This object is first achieved in the case of a multi-chamber hollow profile of the type mentioned at the beginning and described in more detail above in that a filler which has both fire-retarding and heat-insulating fire properties is used as the filler material in the further hollow chamber / s.
- hydrophilic mineral fillers are already known that react with a blowing agent that releases gases through chemical or biochemical reactions and penetrates the filler.
- the filler combines with still air (bubbles) for thermal insulation. This reaction process is expediently triggered by water and also binds part of the liquid for fire retardancy.
- a mixture of an inorganic mineral and water and hydrogen peroxide are used as blowing agents as filler.
- the percentage distribution of the individual parts is adapted to the respective requirements of the fire protection door / window. In this way, an optimal adaptation of the multi-chamber hollow profiles to be produced can be set individually for the respective purpose.
- An automatically foaming and self-curing inorganic mineral foam as a filler is known per se and in the DE 10 2016 001 930 A1 described in more detail.
- the known mineral foam can be processed at ambient pressure and ambient temperature and is therefore particularly suitable as a filler for the multi-chamber hollow profile according to the invention.
- the inner and the outer hollow profile consist of metal, preferably of aluminum.
- Aluminum offers sufficient stability and, in the event of a fire, meets the requirements of a sufficiently long stability.
- a further teaching of the invention provides that the two hollow profiles have at least one anchoring web in the region of the further hollow chamber / s on their outside facing the respective other hollow profile.
- the connecting webs have one or more anchoring webs. This also allows the area for the connection of the multi-chamber hollow profile to the filling material to be increased still further.
- the connecting webs consist of a thermoplastic, preferably polyamide (PA). Sufficient strength with good thermal insulation is thus achieved for the further hollow chambers that arise.
- PA polyamide
- the object is achieved in that the filling material is poured into the further hollow chamber (s) as a flowable mixture and cures there.
- the filling material is mixed in a predetermined ratio and then filled into the cavity of the respective further hollow chamber / s of the multi-chamber hollow profile by means of at least one lance, the lance being filled up to the end of the further hollow chamber / s before this / n is inserted and is evenly pulled out of the further hollow chamber / s to be filled during the filling process.
- This type of filling achieves reliable complete filling and an optimal distribution and uniform density of the filling material in the interior of the multi-chamber hollow profile according to the invention.
- the properties of the filler material can be adjusted according to the requirements, both with regard to their fire-retarding and also with regard to their heat-insulating properties, by means of a production-specific process control.
- the flow rate of the mixture, the delivery rate when filling and the speed of the lance when pulling out of the multi-chamber hollow profile can be varied in order to adjust the physical and material-specific properties of the filling material to the respective intended use to be able to.
- the object is achieved in a device for producing a multi-chamber hollow profile according to the invention in that a plurality of parallel arranged and prepared multi-chamber hollow profiles are clamped side by side and / or one above the other and arranged inclined to the horizontal and successively from an axially movable and perpendicular to their longitudinal axis in the direction of filling multi-chamber hollow profiles movable lance can be filled.
- such a device has a storage container for receiving the premixed filling material and at least one pump, by means of which the filling material and preferably a shut-off valve for filling the multi-chamber hollow profiles are conveyed into the lance.
- the lance can be moved in its axial direction and can be moved perpendicularly in order to move the cavities to be filled in and out into the multi-chamber hollow profiles clamped next to and / or one above the other for the filling process.
- the device according to the invention also includes designs with a plurality of lances.
- FIG. 1A A multi-chamber hollow profile 1 for a fire door or a fire protection window is shown with an outer hollow profile 2A and an inner hollow profile 2B, the outer hollow profile 2A being connected to the inner hollow profile 2B via two connecting webs 3.
- a third hollow chamber 4 is formed, which is filled with a filling material, which is shown in FIG Fig. 1A is not shown.
- both the outer hollow profile 2A and the inner hollow profile 2B have a plurality of anchoring webs 5 on the mutually facing outer sides, which form a positive connection with the hardened filler material (not shown).
- the filling material that is introduced into the hollow chamber 4 has both fire-retardant and heat-insulating properties.
- outer and inner hollow profiles 2A and 2B shown is selected at random and is not intended to limit the exemplary embodiment of the present invention to this. Any hollow profiles are conceivable as long as they can be connected to each other to form a multi-chamber hollow profile only by means of corresponding connecting webs.
- FIG. 1B and 1C show further preferred embodiments, which are compared to Fig. 1A but only differentiate in the design of the anchoring webs.
- the outer hollow profile 2A ' has only one anchoring web 5' centrally on the outside facing the inner hollow profile 2B ', the inner hollow profile 2B' also being symmetrical to the one already has said anchoring web 5 'arranged further anchoring web 5'.
- the multi-chamber hollow profile 1 '' shown essentially corresponds to the multi-chamber hollow profile 1 Fig. 1A . While the two outer and inner hollow profiles 2A '"and 2B'" in the exemplary embodiment shown have no anchoring webs, the modified connecting webs 3 "each have two corresponding inwardly anchoring webs 5"". The omission of the anchoring webs on the outer and inner hollow profiles 2A '"and 2B'" only serves to provide a better overview. Of course, the in Figure 1D connecting webs 3 "shown in the 1A to 1C Use embodiments shown.
- the filling of the hollow chamber 4 with filler as filler material should take place by means of a lance inserted into the hollow chamber 4 and described in more detail later, so that the anchoring webs 5, 5 ', 5 "used do not go too far into the interior of the respective one Hollow chamber 4 should protrude in order to allow a sufficient cross-section for receiving the lance and also a uniform filling of the hollow chamber 4.
- a fire protection door or window In the event of a fire, a fire protection door or window must be able to withstand the temperatures that arise for as long as is required for the respective application (e.g. 30 or 60 minutes; fire protection classes EI 30, EI 60). The overall construction of the multi-chamber profile should remain sufficiently stable.
- Fig. 2 a case is shown in which a fire acts on the inner hollow profile 2B from the inside in the direction of the arrows 7.
- the inner hollow profile 2B melts and certainly also a region of the connecting webs 3, so that as in FIG Fig. 2 shown after melting, the outer hollow profile 2A and any residues 3 'of the partially melted connecting webs 3 are still preserved, the hardened filling 6 inside the further hollow profile 4 (cf. Fig. 1A ) is largely retained thanks to its fire-retardant and heat-insulating properties.
- FIG. 3 A corresponding case is shown in which the fire side acts on the multi-chamber hollow profile according to the invention from the outside, so that after the outer hollow profile 2A has melted, as in the right part of FIG Fig. 3 shown, only the inner hollow profile 2B, remnants of partially melted connecting webs 3 'and the hardened filler material 6 remain.
- the cavity of the further hollow chamber 4 is filled by means of a lance 8, as schematically in FIG Fig. 4 , in which a device for producing a multi-chamber hollow profile according to the invention is shown schematically and shortened in side view, in which the lance 8 can be inserted into the hollow chamber 4 of the multi-chamber hollow profile 1.
- the lance 8 After the lance 8 has been introduced into the hollow chamber 4, the actual filling process begins, in which filler material FM is fed from a reservoir V by means of a pump P via lines 9 and 10 to the upper end of the lance 8.
- a shut-off valve 11 is expediently also present in this area, so that no filling material FM can escape when the lance 8 is inserted into the hollow chamber 4 of the multi-chamber hollow profile 1.

Hieraus ergibt sich ebenfalls die Problematik einer entsprechenden hohen Variante bei unterschiedlichen Profilgrößen. Aus der Offenlegungsschrift
Seit einigen Jahren kommen Brandschutztüren immer häufiger in der Außenanwendung zum Einsatz. Grund hierfür ist die immer stärkere Bauraumverdichtung in den Städten. Gebäude rücken immer näher zusammen und ein Überschlag eines Brandes von einem Gebäude auf das andere oder auf andere Gebäudeteile muss verhindert werden. Aufgrund dieses wachsenden Einsatzbereichs für Brandschutztüren und -fenster kommen auch neue Leistungsanforderungen wie Wind- und Schlagregenschutz, aber auch der Wärmeschutz auf die verwendeten Mehrkammerhohlprofile zu.Fire protection doors have been used in outdoor applications for a number of years. The reason for this is the increasing density of installation space in cities. Buildings are moving closer together and a fire spreading from one building to another or to other parts of the building must be prevented. Due to this growing area of application for fire protection doors and windows, new performance requirements such as wind and driving rain protection as well as thermal protection also come up to the multi-chamber hollow profiles used.
Gerade der energetische Wärmeschutz unterscheidet sich Signifikat vom brandschutztechnischen. Während beim energetische Wärmeschutz möglichst wenig thermische Energie durch die Tür verloren gehen soll, ist beim Brandschutz möglichst viel Energie durch die Tür bzw. durch ihre Komponenten zu verbrauchen, um möglichst lange einem Brand standzuhalten. Bei thermisch getrennten Profilen im Brandschutz erfolgt ein minimaler Wärmeschutz, wie bei den in der
Die der Erfindung zugrunde liegende Aufgabe besteht darin, ein Brandschutz-Profilsystem zu entwickeln, das aus Hohlprofilen besteht, welche durch eine thermische Trennung miteinander verbunden sind.The object on which the invention is based is to develop a fire protection profile system which consists of hollow profiles which are connected to one another by a thermal separation.
Diese Aufgabe wird zunächst bei einem Mehrkammerhohlprofil der eingangs genannten und zuvor näher beschriebenen Art dadurch gelöst, dass als Füllmaterial in der/den weiteren Hohlkammer/n ein Füllstoff eingesetzt wird, der sowohl brandhemmende als auch wärmedämmende Brandeigenschaften aufweist.This object is first achieved in the case of a multi-chamber hollow profile of the type mentioned at the beginning and described in more detail above in that a filler which has both fire-retarding and heat-insulating fire properties is used as the filler material in the further hollow chamber / s.
Diese materialspezifischen Eigenschaften des Füllstoffs lassen sich sowohl hinsichtlich ihrer brandhemmenden aber auch hinsichtlich ihrer wärmedämmenden Eigenschaften, je nach Anforderung, einstellen. Um die Verarbeitung zu erleichtern, ist in der/den zwischen den Hohlprofilen und den Verbindungsstegen entstehenden Hohlkammer/n auf zusätzliche hitzebeständige mechanische Verbindungselemente verzichtet worden.These material-specific properties of the filler can be adjusted depending on the requirements, both with regard to their fire-retardant and also with regard to their heat-insulating properties. In order to facilitate processing, additional heat-resistant mechanical connecting elements have been dispensed with in the hollow chamber (s) formed between the hollow profiles and the connecting webs.
Für die brandhemmende Eigenschaft sind für sich schon hydrophile mineralische Füllstoffe bekannt, die mit einem Treibmittel reagieren, das durch chemische oder biochemische Reaktionen Gase freisetzt und den Füllstoff durchdringt. Darüber hinaus verbindet sich der Füllstoff für eine Wärmedämmung mit ruhender Luft (Blasen). Zweckmäßiger Weise wird dieser Reaktionsprozess durch Wasser ausgelöst und bindet auch einen Teil der Flüssigkeit für die Brandhemmung.For the fire-retardant property, hydrophilic mineral fillers are already known that react with a blowing agent that releases gases through chemical or biochemical reactions and penetrates the filler. In addition, the filler combines with still air (bubbles) for thermal insulation. This reaction process is expediently triggered by water and also binds part of the liquid for fire retardancy.
Als Füllmaterial wird ein Gemisch aus einem anorganischen Mineralstoff und Wasser sowie Wasserstoffperoxid als Treibmittel verwendet. Die prozentuale Verteilung der einzelnen Anteile ist dabei an die jeweiligen Anforderungen der/des Brandschutztür/- fensters angepasst. Auf diese Weise lässt sich eine optimale Anpassung der herzustellenden Mehrkammerhohlprofile für den jeweiligen Zweck individuell einstellen.A mixture of an inorganic mineral and water and hydrogen peroxide are used as blowing agents as filler. The percentage distribution of the individual parts is adapted to the respective requirements of the fire protection door / window. In this way, an optimal adaptation of the multi-chamber hollow profiles to be produced can be set individually for the respective purpose.
Ein selbsttätig aufschäumender und selbsttätig aushärtender anorganischer Mineralschaum als Füllstoff ist für sich bekannt und in der
In weiterer Ausgestaltung der Erfindung bestehen das innere und das äußere Hohlprofil aus Metall, vorzugsweise aus Aluminium. Aluminium bietet eine ausreichende Stabilität und erfüllt im Brandfall die Erfordernisse einer ausreichend langen Standfestigkeit.In a further embodiment of the invention, the inner and the outer hollow profile consist of metal, preferably of aluminum. Aluminum offers sufficient stability and, in the event of a fire, meets the requirements of a sufficiently long stability.
Eine weitere Lehre der Erfindung sieht vor, dass die beiden Hohlprofile auf ihrer zum jeweiligen anderen Hohlprofil gerichteten Außenseite wenigstens einen Verankerungssteg im Bereich der weiteren Hohlkammer/n aufweisen. Durch die entsprechende Auslegung wird der zu verfüllende Hohlraum segmentiert und eine größere Fläche für die Verbindung des Füllmaterials erzeugt.A further teaching of the invention provides that the two hollow profiles have at least one anchoring web in the region of the further hollow chamber / s on their outside facing the respective other hollow profile. Through the appropriate design, the cavity to be filled is segmented and a larger area is created for the connection of the filling material.
In bevorzugter Weiterbildung der Erfindung ist es auch zweckmäßig, wenn die Verbindungsstege einen oder mehrere Verankerungsstege aufweisen. Auch dadurch kann die Fläche für die Verbindung des Mehrkammerhohlprofils mit dem Füllmaterial noch weiter erhöht werden.In a preferred development of the invention, it is also expedient if the connecting webs have one or more anchoring webs. This also allows the area for the connection of the multi-chamber hollow profile to the filling material to be increased still further.
In einer weiteren bevorzugten Ausgestaltung der Erfindung bestehen die Verbindungsstege aus einem thermoplastischen Kunststoff, vorzugsweise Polyamid (PA). Damit wird für die entstehenden weiteren Hohlkammern eine ausreichende Festigkeit bei guter Wärmedämmung erreicht.In a further preferred embodiment of the invention, the connecting webs consist of a thermoplastic, preferably polyamide (PA). Sufficient strength with good thermal insulation is thus achieved for the further hollow chambers that arise.
