Definitions
- the invention relates to a wing-frame construction such as doors or windows with a fire retardant and the use of a fire retardant in a wing-frame construction with the features of the preamble of the independent claims.
- Such fire retardants should serve to improve the fire protection properties of wing frame constructions.
- Another solution is to prevent the hydraulic oil from escaping in the event of fire, for example from a door closer.
- the DE 19515169 C2 describes a door with a door closer attached to the door outside.
- the door closer is attached to the door with a melt-down fastener so that it will come off the door in case of fire before the hydraulic oil can catch fire. This prevents hydraulic oil escaping from the door closer in case of fire from spilling over the door and possibly expanding the fire.
- This construction has the disadvantage that it is not suitable for door closers hidden in the door leaf or door frame because the door closer remains trapped in the construction in case of fire.
- this object is achieved with a wing frame construction and the use of a fire retardant with the features of the characterizing part of the independent claims.
- the wing frame construction comprises a wing profile, which is connected to a frame profile or connectable.
- the wing profile may belong to a door or a window, which may be connected by means of bands with the door or window frame profile pivotally.
- a mechanical part is arranged or can be arranged, which contains a flammable fluid.
- fluid herein is meant both gases and liquids.
- the mechanical part is a door closer, which is mounted in particular concealed lying on the wing or frame profile.
- At least one fire retardant is arranged adjacent to the mechanical part.
- adjacent is meant an arrangement which ensures a hydraulic connection between the fire retardant and the mechanical part, so that the fluid can flow from the mechanical part to the fire retardant.
- the fire retardant is such that the fluid exiting the mechanical part is absorbable in the fire retardant. If the mechanical part is a door closer, the fluid is, for example, a hydraulic oil.
- Such a wing-frame construction has the advantage that in case of fire, the fluid from the fire retardant can be at least partially absorbed. This reduces the amount of fluid that can even catch on fire. In case of fire released hydraulic oil gases of the door closer can develop only to a small extent. In addition, it can also largely be prevented that the fluid reaches the wing or frame profile surface and ignites there. Thereby, the fire resistance of such a construction can be increased. With the arrangement according to the invention it was possible, surprisingly, to complete a positive fire test even with uninsulated profiles.
- the mechanical part may, however, also be, for example, a lock bolt or other fittings, which may likewise comprise a fluid. These parts also usually have lubricants that can ignite in case of fire.
- the wing profile and / or the frame profile is designed as a hollow profile or multi-chamber profile, for example made of steel or stainless steel.
- the mechanical part, such as the door closer, and the fire retardant can be obscured be arranged in the hollow profile or multi-chamber profile.
- the wing or frame profile can be isolated or uninsulated profiles.
- the use of hollow profiles or multi-chamber profiles allows, for example, the installation of concealed door closers. This has aesthetic advantages and provides for a mechanical and thermal protection of the arranged in the hollow profile or multi-chamber profile mechanical parts, especially in case of fire.
- the mechanical part is arranged between two fire retardants.
- the flame retardants are as close as possible to the closing means (door closers, etc.) arranged in order to absorb the fluid already at the source can. This also reduces the risk of fire in the hollow profile or multi-chamber profile. It is also conceivable alternatively or additionally to arrange a fire retardant under the mechanical part. The placement of the fire retardant depends in particular on the geometric relationships of the hollow or multi-chamber profiles.
- two partitions are arranged in the hollow profile or multi-chamber profile such that the mechanical part and the fire retardants come to rest between the partitions.
- the mechanical part and the fire retardants are thereby delimited from the adjacent cavity of the hollow profile or multi-chamber profile and the potential source of fire can be localized.
- the partitions are preferably made of a steel or stainless steel sheet, which substantially corresponds to the cross-sectional area of the cavity.
- the partitions are, for example, stapled or welded into the cavity.
- the fire retardant preferably comprises a porous, heat-resistant material.
- the fire retardant can thereby largely absorb and bind the fluid, in particular the oil.
- the fire retardant comprises a material containing absorbed water so that dehydration may take place in the event of fire.
- the dehydration is an endothermic reaction, so that the fire retardant and thus the absorbed fluid is cooled.
- the cooling also counteracts the evaporation of the fluid.
- the fire retardant is made of aerated concrete / aerated concrete or gypsum.
- Such fire retardants are easy and inexpensive to manufacture. Suitable are e.g. also materials which contain a heat-binding hydrophobic material such as zeolites.
- foam concrete, a normal concrete porosized by foaming or expanding can also be used.
- the fire retardant fills the hollow profile or multi-chamber profile in cross-section substantially completely.
- a largest possible storage volume for the fluid with the least possible distance from the source of the fluid can be arranged.
- the fire retardant preferably has a length of at least about 7 to 10 cm. This results in a volume which is sufficient for the absorption of the fluid. Of course, other lengths are conceivable, it is important that the volume of the fire retardant is large enough to absorb the fluid.
- one or more openings such as e.g. Be arranged holes.
- the surface of the fire retardant and thus its suction rate is increased.
- the fire retardant is preferably formed substantially cuboid and has a rectangular cross-section recess for receiving a profile groove. Such geometry can be easily manufactured and inserted in during assembly in the hollow profile or multi-chamber profile.
- the fire retardant can also be provided loosely in the form of bulk material, granules or portions. This increases the flexibility of assembly for different hollow profile cross-sections.
- an absorbent refractory material in particular aerated concrete, for absorbing a fluid emerging from a mechanical part, in particular a door closer, such as e.g. a hydraulic oil.
- this material is a previously described fire retardant in the wing-frame construction described above.
- heat-resistant is meant a material which is more resistant to heat than the exiting fluid.
- a material is heat-resistant in the sense of the present application if it complies with the relevant fire safety standards, such as, for example, which can fulfill EN 1363-1.
- FIG. 1 shows an inventive wing frame construction 1 using the example of a profile door of the Forster presto® system of the applicant. Only the upper part of the wing frame construction 1 is shown here.
- a frame profile 3 made of steel
- a likewise made of steel sash profile 2 is arranged, which is fastened to the frame profile 3 about the belt axis 12 pivotally via bands, not shown here.
- a door closer 4 is arranged, which contains a hydraulic oil. About an adjusting screw 13, the closing force of the door closer 4 is adjustable.
- a lever 14 is pivotally mounted, which along a frame profile 3 attachable slide rail 15 (see FIG. 2 ) can move.
- Left and right of the door closer 4 is arranged at a distance of about 1 cm from an end face 16 and the adjusting screw 13 each have a flame retardant 5 in the sash profile 2.
- These flame retardants 5 are cuboidal gas concrete shaped pieces whose geometry is made with 1 mm of circulating air to the contour of the wing profile 2.
- a steel profile 17 is arranged below the door closer 4, which counteracts a distortion of the sash profile 2 due to one-sided heating in case of fire.
- the left, band-side fire retardant 5 has a length of 7 cm, the right fire retardant 5 may have a variable length, but in this embodiment should be at least 10 cm long.
- the height of the fire retardant is 4 cm in this example. For 60 mm profiles, of course, different masses are necessary.
- the flame retardants 5 are both separated via partitions 6 from the cavity 7.
- the dividing wall 6 is attached to the vertical wing profile 2 in the band-side fire retardant 5.
- the partition wall 6 at the right fire retardant 5 is mounted directly on an end face of the fire retardant 5.
- the partitions 6 have laterally projecting mounting wings 18 and the partitions 6 correspond to the contour of the sash profile second
- FIG. 2 shows a cross section in the plane AA of FIG. 1 ,
- the door closer 4 has a hydraulic cylinder 19 which contains a hydraulic oil.
- the door closer 4 is integrated into the sash profile 2 and the slide rail 15 was installed in the frame profile 3. Is the sash profile 2 in a closed position as in FIG. 2 , no components of the door closer 4 are visible.
- the lever 14 is arranged, which connects a movable in the slide rail 15 back and forth slider 21 with the door closer 4.
- the hydraulic oil heats up and exits the door closer 4 in the cavity 7 of the sash profile 2.
- the hydraulic oil is now absorbed by the two fire retardants 5.
- FIG. 3 it can be seen, fill the flame retardant 5 and the steel profile 17, the profile contour almost completely.
- the flame retardants 5 have a width of 45 mm and a height of 40 mm. In the area a profile groove 11, the flame retardant 5 has a rectangular recess 10 of about 15 mm to 15 mm.
- FIGS. 4 and 5 show a further embodiment in cross section. This differs from the example in the FIGS. 1 to 3 in that here uninsulated wing profiles 2 were used.
- the fire retardant 5 therefore extend over the entire height of the hollow space 7 of 45 mm.
- FIG. 5 are also holes 9 arranged in the fire retardant 5 to increase the surface of the fire retardant.
- the door closer 4 in the frame profile 3 and to arrange the slide rail 15 in the sash profile 2.
- the flame retardant 5 are also mounted in the frame profile adjacent to the door closer 4.
- one or more flame retardants 5 can also be mounted in the sash profile 2. If only fire retardant 5 are provided in the sash profile 2, it must also be ensured in this arrangement that the hydraulic oil can flow to the fire retardants 5, so that it can be absorbed by the fire retardants.
Abstract
Description
Die Erfindung betrifft eine Flügel-Rahmen Konstruktion wie Türen oder Fenster mit einem Brandhemmer sowie die Verwendung eines Brandhemmers in einer Flügel-Rahmen Konstruktion mit den Merkmalen des Oberbegriffs der unabhängigen Ansprüche.The invention relates to a wing-frame construction such as doors or windows with a fire retardant and the use of a fire retardant in a wing-frame construction with the features of the preamble of the independent claims.
Derartige Brandhemmer sollen dazu dienen, die Brandschutzeigenschaften von Flügel-Rahmen Konstruktionen zu verbessern.Such fire retardants should serve to improve the fire protection properties of wing frame constructions.
Es ist bekannt, Türen mit Türschliessern zu versehen, mit welchen beispielsweise die Schliesskraft und Schliessgeschwindigkeit einer Tür eingestellt werden können. Solche Türschliesser weisen deshalb in der Regel eine Dämpfungshydraulik auf, welche ein Hydrauliköl enthalten. Im Brandfall werden die mechanischen Teile wie Türschliesser oder Verriegelungsvorrichtungen Temperaturen von mehreren Hundert Grad ausgesetzt. Aufgrund dieser Erwärmung entweichen die in oder an den mechanischen Teilen enthaltenen Öle oder Fette und können sich im Türprofil oder der Türaussenseite entzünden.It is known to provide doors with door closers, with which, for example, the closing force and closing speed of a door can be adjusted. Such door closer therefore usually have a damping hydraulics, which contain a hydraulic oil. In case of fire, the mechanical parts such as door closers or locking devices are exposed to temperatures of several hundred degrees. Due to this heating, the oils or greases contained in or on the mechanical parts escape and may ignite in the door profile or the door outside.
Es ist bekannt, dieses Problem beispielsweise durch die Verwendung von schwer entflammbaren Hydraulikölen zu entschärfen. Die Entflammungstemperatur solcher Öle ist zwar höher, und der Brandwiderstand wird erhöht, jedoch geraten auch diese Öle mit fortschreitender Hitzeeinwirkung in Brand und ein Feuer kann durch die Tür hindurch dringen.It is known to mitigate this problem for example by the use of flame-retardant hydraulic oils. The flammability temperature of such oils is higher, and the fire resistance is increased, but these oils are also set on fire with increasing heat and a fire can penetrate through the door.
Eine weitere Lösung besteht darin, zu verhindern, dass das Hydrauliköl im Brandfall z.B. aus einem Türschliesser überhaupt austreten. Die Kapselung eines Hydraulikzylinders eines Türschliessers um den Ölaustritt im Brandfall zu verhindern ist jedoch aufwändig und unwirtschaftlich.Another solution is to prevent the hydraulic oil from escaping in the event of fire, for example from a door closer. The encapsulation of a hydraulic cylinder of a door closer to prevent the escape of oil in case of fire, however, is complicated and uneconomical.
Die
Es ist deshalb eine Aufgabe der vorliegenden Erfindung, die Nachteile des Bekannten zu vermeiden, insbesondere eine Vorrichtung der eingangs genannten Art zu schaffen, welche gute Brandschutzeigenschaften aufweist und welche insbesondere auf einfache Art und Weise und günstig herstellbar ist.It is therefore an object of the present invention to avoid the disadvantages of the known, in particular to provide a device of the type mentioned, which has good fire protection properties and which in particular in a simple manner and is inexpensive to produce.
Erfindungsgemäss werden diese Aufgabe mit einer Flügel-Rahmen Konstruktion und der Verwendung eines Brandhemmers mit den Merkmalen des kennzeichnenden Teils der unabhängigen Ansprüche gelöst.According to the invention this object is achieved with a wing frame construction and the use of a fire retardant with the features of the characterizing part of the independent claims.
Die Flügel-Rahmen Konstruktion umfasst ein Flügelprofil, welches mit einem Rahmenprofil verbunden oder verbindbar ist. Das Flügelprofil kann zu einer Tür oder einem Fenster gehören, welches mittels Bändern mit dem Tür- bzw. Fensterrahmenprofil schwenkbar verbunden sein kann. Am Flügelprofil oder am Rahmenprofil ist ein mechanisches Teil angeordnet oder anordenbar, welches ein entflammbares Fluid enthält. Mit Fluid sind vorliegend sowohl Gase als auch Flüssigkeiten gemeint. Bevorzugt handelt es sich beim mechanischen Teil um einen Türschliesser, welcher insbesondere verdeckt liegend am Flügel- oder Rahmenprofil montiert ist.The wing frame construction comprises a wing profile, which is connected to a frame profile or connectable. The wing profile may belong to a door or a window, which may be connected by means of bands with the door or window frame profile pivotally. On the wing profile or on the frame profile, a mechanical part is arranged or can be arranged, which contains a flammable fluid. By fluid herein is meant both gases and liquids. Preferably, the mechanical part is a door closer, which is mounted in particular concealed lying on the wing or frame profile.
Am Flügelprofil und/oder Rahmenprofil ist benachbart zum mechanischen Teil mindestens ein Brandhemmer angeordnet. Unter benachbart ist eine Anordnung zu verstehen, welche ein hydraulische Verbindung zwischen Brandhemmer und dem mechanischen Teil gewährleist, so dass das Fluid vom mechanischen Teil zum Brandhemmer fliessen kann. Der Brandhemmer ist derart beschaffen, dass das aus dem mechanischen Teil austretende Fluid im Brandhemmer aufsaugbar ist. Ist das mechanische Teil ein Türschliesser, handelt es sich beim Fluid beispielsweise um ein Hydrauliköl.On the sash profile and / or frame profile, at least one fire retardant is arranged adjacent to the mechanical part. By adjacent is meant an arrangement which ensures a hydraulic connection between the fire retardant and the mechanical part, so that the fluid can flow from the mechanical part to the fire retardant. The fire retardant is such that the fluid exiting the mechanical part is absorbable in the fire retardant. If the mechanical part is a door closer, the fluid is, for example, a hydraulic oil.
Eine solche Flügel-Rahmen Konstruktion hat den Vorteil, dass im Brandfall das Fluid vom Brandhemmer mindestens teilweise aufgesogen werden kann. Dadurch verringert sich die Menge des Fluids, welches überhaupt in Brand geraten kann. Im Brandfall frei werdende Hydrauliköl-Gase des Türschliessers können sich nur in geringem Masse entwickeln. Zudem kann auch weitgehend verhindert werden, dass das Fluid an die Flügel- oder Rahmenprofiloberfläche gelangt und sich dort entzündet. Dadurch kann der Feuerwiderstand einer solchen Konstruktion erhöht werden. Mit der erfindungsgemässen Anordnung konnte völlig überraschend eine positive Brandprüfung auch mit unisolierten Profilen absolviert werden.Such a wing-frame construction has the advantage that in case of fire, the fluid from the fire retardant can be at least partially absorbed. This reduces the amount of fluid that can even catch on fire. In case of fire released hydraulic oil gases of the door closer can develop only to a small extent. In addition, it can also largely be prevented that the fluid reaches the wing or frame profile surface and ignites there. Thereby, the fire resistance of such a construction can be increased. With the arrangement according to the invention it was possible, surprisingly, to complete a positive fire test even with uninsulated profiles.
Das mechanische Teil kann aber beispielsweise auch ein Schliessriegel oder andere Beschläge sein, welche ebenfalls ein Fluid umfassen können. Auch diese Teile weisen in der Regel Schmiermittel auf, welche sich im Brandfall entzünden können.The mechanical part may, however, also be, for example, a lock bolt or other fittings, which may likewise comprise a fluid. These parts also usually have lubricants that can ignite in case of fire.
Bevorzugt ist das Flügelprofil und/oder das Rahmenprofil als Hohlprofil oder Mehrkammerprofil, beispielsweise aus Stahl oder Edelstahl ausgebildet. In diesem Fall können das mechanische Teil, wie z.B. der Türschliesser, und der Brandhemmer verdeckt im Hohlprofil oder Mehrkammerprofil angeordnet sein. Beim Flügel- bzw. Rahmenprofil kann es sich um isolierte oder unisolierte Profile handeln. Die Verwendung von Hohlprofilen oder Mehrkammerprofilen erlaubt z.B. das Anbringen verdeckt liegender Türschliesser. Dies hat ästhetische Vorteile und sorgt für einen mechanischen und thermischen Schutz der im Hohlprofil oder Mehrkammerprofil angeordneten mechanischen Teile, insbesondere im Brandfall.Preferably, the wing profile and / or the frame profile is designed as a hollow profile or multi-chamber profile, for example made of steel or stainless steel. In this case, the mechanical part, such as the door closer, and the fire retardant can be obscured be arranged in the hollow profile or multi-chamber profile. The wing or frame profile can be isolated or uninsulated profiles. The use of hollow profiles or multi-chamber profiles allows, for example, the installation of concealed door closers. This has aesthetic advantages and provides for a mechanical and thermal protection of the arranged in the hollow profile or multi-chamber profile mechanical parts, especially in case of fire.
Vorzugsweise ist das mechanische Teil zwischen zwei Brandhemmern angeordnet. Dadurch kann das Fluid unabhängig auf welche Seite es fliesst (z.B. wenn das Türprofil nicht genau im Lot montiert wurde), aufgesogen werden. Vorzugsweise sind die Brandhemmer möglichst dicht am Schliessmittel (Türschliesser usw.) angeordnet, um das Fluid schon an der Quelle aufsaugen zu können. Dadurch wird auch das Risiko eines Brands im Hohlprofil oder Mehrkammerprofil verringert. Es ist auch denkbar, alternativ oder zusätzlich einen Brandhemmer unter dem mechanischen Teil anzuordnen. Die Platzierung der Brandhemmer hängt insbesondere von den geometrischen Verhältnissen der Hohl- bzw. Mehrkammerprofile ab.Preferably, the mechanical part is arranged between two fire retardants. This allows the fluid to be absorbed independently of which side it is flowing (e.g., if the door profile has not been accurately plumbed). Preferably, the flame retardants are as close as possible to the closing means (door closers, etc.) arranged in order to absorb the fluid already at the source can. This also reduces the risk of fire in the hollow profile or multi-chamber profile. It is also conceivable alternatively or additionally to arrange a fire retardant under the mechanical part. The placement of the fire retardant depends in particular on the geometric relationships of the hollow or multi-chamber profiles.
Vorzugsweise sind im Hohlprofil oder Mehrkammerprofil zwei Trennwände derart angeordnet, dass das mechanische Teil und die Brandhemmer zwischen die Trennwände zu liegen kommen. Das mechanische Teil und die Brandhemmer werden dadurch vom angrenzenden Hohlraum des Hohlprofils oder Mehrkammerprofils abgegrenzt und der potenzielle Brandherd kann lokal begrenzt werden. Die Trennwände bestehen bevorzugt aus einem Stahl- oder Edelstahlblech, welches im Wesentlichen der Querschnittsfläche des Hohlraums entspricht. Die Trennwände werden z.B. in den Hohlraum eingeheftet oder eingeschweisst.Preferably, two partitions are arranged in the hollow profile or multi-chamber profile such that the mechanical part and the fire retardants come to rest between the partitions. The mechanical part and the fire retardants are thereby delimited from the adjacent cavity of the hollow profile or multi-chamber profile and the potential source of fire can be localized. The partitions are preferably made of a steel or stainless steel sheet, which substantially corresponds to the cross-sectional area of the cavity. The partitions are, for example, stapled or welded into the cavity.
Der Brandhemmer umfasst bevorzugt ein poröses, hitzebeständiges Material. Der Brandhemmer kann dadurch das Fluid, insbesondere das Öl weitgehend aufsaugen und binden. Bevorzugt umfasst der Brandhemmer ein Material, das absorbiertes Wasser enthält, so dass im Brandfall eine Dehydratisierung stattfinden kann. Die Dehydratisierung ist eine endotherme Reaktion, sodass der Brandhemmer und damit auch das aufgesogene Fluid gekühlt wird. Die Kühlung wirkt auch der Verdampfung des Fluids entgegen. Vorzugsweise ist der Brandhemmer aus Gasbeton/Porenbeton oder Gips gefertigt. Solche Brandhemmer sind einfach und günstig herzustellen. Geeignet sind z.B. auch Materialien, welche ein wärmebindendes hydrophobes Material wie Zeolithe enthalten. Beispielsweise kann auch Schaumbeton, ein durch Schäumen oder Blähen porosierter Normalbeton verwendet werden.The fire retardant preferably comprises a porous, heat-resistant material. The fire retardant can thereby largely absorb and bind the fluid, in particular the oil. Preferably, the fire retardant comprises a material containing absorbed water so that dehydration may take place in the event of fire. The dehydration is an endothermic reaction, so that the fire retardant and thus the absorbed fluid is cooled. The cooling also counteracts the evaporation of the fluid. Preferably, the fire retardant is made of aerated concrete / aerated concrete or gypsum. Such fire retardants are easy and inexpensive to manufacture. Suitable are e.g. also materials which contain a heat-binding hydrophobic material such as zeolites. For example, foam concrete, a normal concrete porosized by foaming or expanding can also be used.
Vorzugsweise füllt der Brandhemmer das Hohlprofil oder Mehrkammerprofil im Querschnitt im Wesentlichen vollständig aus. Dadurch kann ein grösstmögliches Speichervolumen für das Fluid mit dem geringst möglichen Abstand zur Quelle des Fluids angeordnet werden.Preferably, the fire retardant fills the hollow profile or multi-chamber profile in cross-section substantially completely. Thereby, a largest possible storage volume for the fluid with the least possible distance from the source of the fluid can be arranged.
Der Brandhemmer hat bevorzugt eine Länge von mindestens ca. 7 bis 10 cm. Das ergibt ein Volumen, welches für das Aufsaugen des Fluids genügt. Selbstverständlich sind auch andere Längen denkbar, wichtig ist, dass das Volumen des Brandhemmers genügend gross ist, um das Fluid aufzunehmen.The fire retardant preferably has a length of at least about 7 to 10 cm. This results in a volume which is sufficient for the absorption of the fluid. Of course, other lengths are conceivable, it is important that the volume of the fire retardant is large enough to absorb the fluid.
An einer Oberfläche des Brandhemmers kann eine oder mehrere Öffnungen wie z.B. Bohrungen angeordnet sein. Dadurch wird die Oberfläche des Brandhemmers und damit dessen Saugrate erhöht.On one surface of the fire retardant, one or more openings such as e.g. Be arranged holes. As a result, the surface of the fire retardant and thus its suction rate is increased.
Der Brandhemmer ist vorzugsweise im Wesentlichen quaderförmig ausgebildet und weist eine im Querschnitt rechteckige Aussparung für die Aufnahme einer Profilnut auf. Eine solche Geometrie lässt sich einfach herzustellen und in bei der Montage in das Hohlprofil oder Mehrkammerprofil einschieben.The fire retardant is preferably formed substantially cuboid and has a rectangular cross-section recess for receiving a profile groove. Such geometry can be easily manufactured and inserted in during assembly in the hollow profile or multi-chamber profile.
Der Brandhemmer kann auch lose in Form von Schüttgut, Granulat oder Portionen vorgesehen sein. Dadurch wird die Flexibilität bei der Montage für unterschiedliche Hohlprofilquerschnitte erhöht.The fire retardant can also be provided loosely in the form of bulk material, granules or portions. This increases the flexibility of assembly for different hollow profile cross-sections.
Ein anderer Aspekt umfasst die Verwendung eines saugfähigen hitzebeständigen Materials, insbesondere Gasbeton, zum Aufsaugen eines aus einem mechanischen Teil, insbesondere einem Türschliesser, austretenden Fluids wie z.B. eines Hydrauliköls. Bevorzugt handelt es sich bei diesem Material um einen vorhergehend beschriebenen Brandhemmer in der oben beschriebenen Flügel-Rahmen Konstruktion. Unter hitzebeständig ist ein Material zu verstehen, welches hitzebeständiger ist als das austretende Fluid. Typischerweise ist ein Material dann hitzebeständig im Sinne der vorliegenden Anmeldung, wenn es die einschlägigen Brandschutznormen wie z.B. die EN 1363-1 erfüllen kann.Another aspect involves the use of an absorbent refractory material, in particular aerated concrete, for absorbing a fluid emerging from a mechanical part, in particular a door closer, such as e.g. a hydraulic oil. Preferably, this material is a previously described fire retardant in the wing-frame construction described above. By heat-resistant is meant a material which is more resistant to heat than the exiting fluid. Typically, a material is heat-resistant in the sense of the present application if it complies with the relevant fire safety standards, such as, for example, which can fulfill EN 1363-1.
Der Vorteil dieser Verwendung liegt darin, dass bei einem Brand das Fluid vom Material aufgesaugt und gebunden wird und damit der Verbrennung weitgehend entzogen wird.The advantage of this use is that in a fire, the fluid is absorbed by the material and bound and thus the combustion is largely removed.
