Description

Die Erfindung betrifft eine wärmeisolierende und feuerhemmende Verbundplatte mit einem ersten Plattenelement aus gepreßter Mineralwolle und einer dünnen und wärmebeständigen Reflexionsfolie aus Aluminium, deren eine Seite mittels einer ersten Leimschicht aus einem Wasserglasleim mit einer der flächigen Seiten des Plattenelements verbunden ist.The invention relates to a heat-insulating and fire-retardant composite panel with a first panel element made of pressed mineral wool and a thin and heat-resistant reflective foil made of aluminum, one side of which is connected to one of the flat sides of the panel element by means of a first layer of glue made from water glass glue.

Die Reflexionsfolie einer derartigen Verbundplatte kann ihre wärmeabstrahlende und wärmereflektierende Wirkung nur dann entfalten, wenn sie bei einem Feuer unzerstört bleibt. Wird sie aber einer zu großen Hitze ausgesetzt, so besteht die Gefahr, daß die Reflexionsfolie aus Aluminium aufplatzt und dann die Wärmestrahlung ungehindert zu dem darüber befindlichen Plattenelement aus Mineralwolle gelangt, welches alsdann ebenfalls zerstört wird.The reflective film of such a composite panel can only develop its heat-radiating and heat-reflecting effect if it remains undamaged in a fire. However, if it is exposed to excessive heat, there is a risk that the aluminum reflection foil will burst and then the heat radiation can reach the mineral wool plate element above it, which is then also destroyed.

Eine Verbundplatte mit den eingangs genannten Merkmalen beschreibt die FR-A 2 294 840. Ihre feuerhemmende Wirkung ist aber aus den vorstehend geschilderten Gründen nur begrenzt.FR-A 2 294 840 describes a composite panel with the features mentioned at the beginning. However, its fire-retardant effect is only limited for the reasons described above.

Die DE-A-2 606159 beschreibt eine Verbundplatte mit mehreren Schichten aus Polyurethanschaum, die mit einer Aluminiumfolie abgedeckt sind, die sich auch zwischen den Schichten aus dem Polyurethanschaum befindet. Die Schichten sind miteinander verschweißt. Polyurethanschaum schmilzt bei entsprechenden Temperaturen sehr leicht, so daß diese bekannte Verbundplatte keine feuerhemmenden Eigenschaften hat. Zum Schutz der Schichten aus Polyurethanschaum ist auf die unterste Schicht eine Schutzschicht aus Aluminiumfolie aufgeklebt. Aber auch diese Schutzschicht wird bei einem Feuer oder bei einer größeren Wärmeentwicklung direkt und ungeschützt der Wärmestrahlung ausgesetzt, platzt dann und kann die über ihr befindlichen Schichten nicht mehr wirksam schützen.DE-A-2 606159 describes a composite panel with several layers of polyurethane foam, which are covered with an aluminum foil, which is also located between the layers of polyurethane foam. The layers are welded together. Polyurethane foam melts very easily at appropriate temperatures, so that this known composite panel has no fire-retardant properties. To protect the layers of polyurethane foam, a protective layer of aluminum foil is glued to the bottom layer. However, this protective layer is also exposed directly and unprotected to the heat radiation in the event of a fire or in the event of greater heat development, then bursts and can no longer effectively protect the layers located above it.

Der Erfindung liegt die Aufgabe zugrunde, eine Verbundplatte der eingangs genannten Art vorzuschlagen, deren feuerhemmende Wirkung fühlbar verbessert ist.The invention has for its object to propose a composite panel of the type mentioned, the fire retardant effect is noticeably improved.

Zur Lösung dieser Aufgabe ist die Erfindung dadurch gekennzeichnet, daß die Verbundplatte ein zweites Plattenelement aus gepreßter Mineralwolle aufweist, das mit der anderen Seite der Reflexionsfolie über eine zweite Leimschicht aus einem Wasserglasleim verbunden ist. Die Reflexionsfolie wird somit durch das zweite Plattenelement aus gepreßter Mineralwolle geschützt, so daß ein fühlbarer mechanischer und wärmeisolierender Schutz für die empfindliche Reflexionsfolie besteht. Die Reflexionsfolie wird zwischen den beiden Plattenelementen fernerhin gut plan gehalten und kann sich nicht mehr ohne weiteres aufwellen und zerreißen oder aufplatzen.To achieve this object, the invention is characterized in that the composite plate has a second plate element made of pressed mineral wool, which is connected to the other side of the reflective film via a second layer of glue from a water glass glue. The reflective film is thus protected by the second plate element made of pressed mineral wool, so that there is a tangible mechanical and heat-insulating protection for the sensitive reflective film. The reflective film is also kept well planar between the two plate elements and can no longer easily swell and tear or burst.

Die Zeichnungen zeigen sämtliche Bauteile in unmaßstäblichen Größenverhältnissen. Die maßstäblichen Größenverhältnisse sind etwa folgende:

  • Die Verbundplatte 1 besteht nach ihrem gesamten Aufbau aus etwa 2 x 27,5 mm starken Plattenelementen 2,3. Die Plattenelemente bestehen, wie vorher erwähnt, aus einer Mineralfaserwolle.
The drawings show all components in scale. The scale proportions are approximately as follows:
  • The composite plate 1 consists of approximately 2 x 27.5 mm thick plate elements 2, 3 after their entire structure. As previously mentioned, the plate elements consist of a mineral fiber wool.

Die Reflexionsfolie 4 hat eine Dicke von etwa 4/100 mm. Die Leimschichten 5 haben eine Dicke von etwa 50/100 bis 1 mm, die Dicke läßt sich nicht genau bestimmen und ist nur anhand der Fig. 1 schematisiert angedeutet, weil die Leimschichten 5 in den Bereich der fasrigen Plattenelemente reichen und dort einen Übergangsbereich bilden, so daß die Dicke nur ungefähr angegeben werden kann.The reflective film 4 has a thickness of approximately 4/100 mm. The glue layers 5 have a thickness of about 50/100 to 1 mm, the thickness cannot be determined exactly and is only indicated schematically with reference to FIG. 1, because the glue layers 5 extend into the area of the fibrous plate elements and form a transition area there, so that the thickness can only be given approximately.

Das in Fig. 1 gezeigte Verbundplattenelement 1 weist an der Sichtseite 9 eine besonders einfache Konstruktion auf, die noch dazu beiträgt, daß die Feuersicherheit noch um ein weiteres, wesentliches Maß gesteigert ist. Versuche des Anmelders haben nämlich gezeigt, daß die Sichtseite der Verbundplatte unmittelbar mit einer hochwärmefesten Farbschicht 7 versehen werden kann. Eine solche Farbschicht ist z.B. eine Schicht aus Kalkfarbe (schlämme aus gebranntem Kalk in Wasser aufgeschwemmt).The composite panel element 1 shown in Fig. 1 has a particularly simple construction on the visible side 9, which also contributes to the fact that fire safety is increased by a further, essential degree. Tests by the applicant have shown that the visible side of the composite panel can be provided directly with a highly heat-resistant color layer 7. Such a layer of paint is e.g. a layer of lime paint (sludge from burnt lime suspended in water).

Würde man eine solche Farbschicht 7 allein aufbringen, dann besteht der Nachteil, daß sich offene Poren bilden, und hier ein Wärmedurchgang durch das untere Plattenelement 3 möglich ist, so daß die Reflexionsfolie 4 mit der Leimschicht 5 relativ stark schon aufgeheizt wird. Die Farbschicht 7 aus Kalk hat aber den Vorteil, daß sie hochwärmebeständig ist,und die Temperaturen von etwa 1000° C ohne Veränderung übersteht, d.h. es kommt zu keinen Farbveränderungen oder zu Substanzveränderungen.If one were to apply such a color layer 7 alone, then there is the disadvantage that open pores form, and here heat transfer through the lower plate element 3 is possible, so that the reflective film 4 with the glue layer 5 is already heated relatively strongly. However, the color layer 7 made of lime has the advantage that it is highly heat-resistant and survives the temperatures of about 1000 ° C without change, i.e. there are no color changes or substance changes.

Wenn man aber die Feuersicherheit eines solches Plattenelementes noch mehr verbessern will, dann muß man einen luftdichten Abschluß an der Sichtseite 9 her erzielen.But if you have fire safety one want to improve such plate element even more, then you have to achieve an airtight seal on the visible side 9 ago.

Versuche des Anmelders haben nun gezeigt, daß, wenn man eine Mischung aus einer Kalkschlämme mit Wasserglasleim im Verhältnis von etwa 1: 8 wählt, und diese Mischung auf die vorherige Farbschicht 7 aufspritzt, daß die dann so erhaltene zweite Farbschicht 8 einen vollständigen Luftabschluß bildet, und ebenfalls einen hochwärmebeständigen Schutzschild bildet. Es ergibt sich aber damit keine glasartige Schicht, sondern mehr eine elastische, abriebfeste und vollkommen luftdichte Farbschicht, die ein Eindringen von Luft in das untere Plattenelement 2 mit Sicherheit verhindert. Bei einem solchen Verbundplattenelement wird sogar eine Feuersicherheit in der Klasse F120 erzielt, während mit dem vorher beschriebenen Verbundplattenelement ohne die genannten Farbschichten 7 und 8 eine Feuersicherheit von etwa F90 erzielt werden kann.Experiments by the applicant have now shown that if one chooses a mixture of a lime slurry with water glass glue in the ratio of about 1: 8 and sprays this mixture onto the previous paint layer 7, the second paint layer 8 thus obtained forms a complete air seal, and also forms a highly heat-resistant protective shield. However, this does not result in a glass-like layer, but rather in an elastic, abrasion-resistant and completely airtight color layer which reliably prevents air from penetrating into the lower plate element 2. With such a composite panel element, fire safety is even achieved in class F120, while with the previously described composite panel element, a fire security of approximately F90 can be achieved without the aforementioned paint layers 7 and 8.

Die Feuersicherheitsklasse F90 heißt, daß ein solches Element 1 1/2 Stunden lang einer Temperatur von 1000° C an der Sichtseite her standhalten muß, ohne daß es zu Zersetzungen des Plattenelementes kommt, wobei an der Rückseite dieses Plattenelementes an einem Stahlträger lediglich 400°C und an einer Holzkonstruktion lediglich 200°C auftreten dürfen.The fire safety class F90 means that such an element must withstand a temperature of 1000 ° C on the visible side for 1 1/2 hours without the plate element being decomposed, with only 400 ° C on a steel beam on the back of this plate element and only 200 ° C may occur on a wooden structure.

Die Feuersicherheitsklasse F120 heißt, daß die gleichen, vorher genannten Bedingungen 2 Stunden lang aufrechterhalten werden.Fire safety class F120 means that the same conditions mentioned above are maintained for 2 hours.

Die Sichtseite 9 des Verbundplattenelementes zeigt dann die Farbschicht 8, die in der Mischung mit Wasserglas aufgebracht ist, diese Farbschicht kann beliebig eingefärbt werden, und sie kann in beliebigen Strukturen aufgebracht werden. Die Feuereinwirkung erfolgt hierbei in Pfeilrichtung 10.The visible side 9 of the composite panel element then shows the color layer 8, which is applied in the mixture with water glass, this color layer can be colored as desired, and it can be applied in any structure. The fire is affected in the direction of arrow 10.

Fig. 1 zeigt ferner eine besondere Abhängekonstruktion. Die Verbundplattenelemente 1 können unmittelbar auf ein Abhängeprofil 23 aufgelegt werden, und zwar auf die eine Seite des horizontalen Schenkels 24, wobei am vertikalen Schenkel 25 dann eine Einhängeleiste 26 angeordnet ist, die entsprechende Ausnehmungen aufweist, in die die Deckenhaken eingehängt werden.Fig. 1 also shows a special suspension construction. The composite panel elements 1 can be placed directly on a suspension profile 23, to be precise on one side of the horizontal leg 24, with a hanging strip 26 then being arranged on the vertical leg 25, which has corresponding recesses into which the ceiling hooks are hung.

Der Anschluß bzw. die Auflage des Verbundplattenelementes auf dem horizontalen Schenkel 24 ist als dicht zu bezeichnen.The connection or the support of the composite panel element on the horizontal leg 24 can be described as tight.

Die Fig. 2 zeigt, daß die aus den Farbschichten 7,8 bestehende Deckschicht 6 des Verbundplattenelementes 1 auch anders aufgebaut werden kann.FIG. 2 shows that the top layer 6 of the composite panel element 1 consisting of the color layers 7, 8 can also be constructed differently.

In Fig. 2 ist ein Verbundplattenelement 20 gezeigt, das statt der Deckschicht 6 eine Dekorplatte 22 trägt. Diese Dekorplatte 22 ist wiederum mit einer Leimschicht 19 aus Wasserglasleim an der Sichtseite des unteren Plattenelementes 3 angeklebt.FIG. 2 shows a composite panel element 20 which carries a decorative panel 22 instead of the cover layer 6. This decorative plate 22 is in turn glued to the visible side of the lower plate element 3 with a glue layer 19 made of water glass glue.

Die Dekorplatte 22 kann aus verschiedenen Materialien bestehen. Es ist möglich, als Material eine dünne Spanplatte zu verwenden. Die Spanplatte hat hierbei eine Dicke von 4 mm, sie kann aus einer Preßspanplatte oder aus einer furnierten Holzspanplatte bestehen. Die Dekorplatte kann aber auch aus einer Metallplatte bestehen. In einem Feuerversuch würde dann die Dekorplatte verkohlen (sofern sie aus Holz besteht), was aber auf die Feuerbeständigkeit des Verbundplattenelementes 20 keinen Einfluß hat. Es wird noch darauf hingewiesen, daß die Leimschicht 19 während der Hitzeeinwirkung eine Schutzschirm-Funktion hat, und die vorher beschriebenen Verhältnisse in Bezug mit der Reflexionsfolie 4 und den darin ansetzenden Leimschichten 5 nach wie vor bestehen bleiben.The decorative plate 22 can consist of different materials. It is possible to use a thin chipboard as the material. The chipboard has a thickness of 4 mm, it can consist of a chipboard or a veneered chipboard. The decorative plate can also consist of a metal plate. In a fire test, the decorative panel would then carbonize (if it is made of wood), but this has no influence on the fire resistance of the composite panel element 20. It should also be pointed out that the glue layer 19 has a protective shield function during the action of heat, and the conditions described above with respect to the reflective film 4 and the glue layers 5 applied therein still remain.

Das Verbundplattenelement 20 nach Fig. 2 kann mit dem gleichen Abhängesystem verwendet werden, wie nach Fig. 1, d.h. der horizontale Schenkel 24 könnte von unten sichtbar sein.The composite panel element 20 of Figure 2 can be used with the same suspension system as that of Figure 1, i.e. the horizontal leg 24 could be visible from below.

Will man eine solche Aufhängekonstruktion vermeiden, d.h. will man den horizontalen Schenkel 24 nur wenig sichtbar gestalten, dann verwendet man eine umlaufende Nut 21, in deren Bereich der horizontale Schenkel 24 des Abhängeprofils 23 eingehängt wird.If you want to avoid such a suspension construction, i.e. if you want to make the horizontal leg 24 only slightly visible, use a circumferential groove 21, in the area of which the horizontal leg 24 of the suspension profile 23 is hung.

Von unten her ist dann nur noch ein ganz geringer Teil des horizontalen Schenkels des Abhängeprofils 23 zu sehen.From below, only a very small part of the horizontal leg of the suspension profile 23 can be seen.

Auf die Farbschicht (Deckschicht 6) nach Fig. 1 ist es noch möglich, eine zusätzliche Kunststoff-Farbe im Aufspritzverfahren oder Aufziehverfahren aufzubringen. Damit kann jede beliebige Struktur und jede beliebige Farbe oder jedes Oberflächenaussehen erreicht werden.1, it is still possible to apply an additional plastic paint by spraying or drawing. Any structure and color or surface appearance can be achieved with it.

Die Figuren 4, 5 und 6 bis 10 zeigen die Einzelheiten einer abgehängten Deckenkonstruktion mit der Verwendung der bezeichneten Verbundplattenelemente 1 oder 20.Figures 4, 5 and 6 to 10 show the details of a suspended ceiling construction using the designated composite panel elements 1 or 20.

Die Verbundplattenelemente 1 sind mit den stirnseitigen Stoßfugen versetzt zueinander im Verband verlegt. Wandseitig sind Wandwinkel 260 befestigt, auf deren horizontalen Schenkel die Verbundplattenelemente 1 aufliegen. Die Befestigung der Wandwinkel 260 kann über entsprechende Befestigungswinkel 203 an der Wand erfolgen.The composite panel elements 1 are offset from each other in the association with the end joints. On the wall side, wall brackets 260 are attached, on the horizontal leg of which the composite panel elements 1 rest. The wall brackets 260 can be fastened to the wall via corresponding fastening brackets 203.

Die Stöße der Verbundplattenelemente 1 liegen gemäß Fig. 5 auf den horizontalen Schenkeln von Deckenprofilen 201 auf. Der vertikale Schenkel des Deckenprofils 201 weist im Abstand angeordnete Ausnehmungen (Durchbrechungen) auf, durch die das Vertikalprofil eines Quer-Profils 202 hindurchgeschoben ist. Dieses Quer-Profil 202 ist also senkrecht zu dem Längsverlauf des Deckenprofils 201 angeordnet und unterstützt die Verbundplattenelemente an ihren Längsstößen, während die Querstöße von dem Deckenprofil 201 getragen sind. Auf diese Weise ist es möglich, großformatige Verbundplattenelemente, beispielsweise im Format 125 x 62,5 cm, zu verwenden.5, the joints of the composite panel elements 1 lie on the horizontal legs of ceiling profiles 201. The vertical leg of the ceiling profile 201 has recesses (openings) arranged at a distance, through which the vertical profile of a cross profile 202 is pushed. This cross profile 202 is thus arranged perpendicular to the longitudinal profile of the ceiling profile 201 and supports the composite panel elements at their longitudinal joints, while the cross joints are carried by the ceiling profile 201. In this way it is possible to use large format composite panel elements, for example in the format 125 x 62.5 cm.

Im vertikalen Teil des Deckenprofils 201 sind Bohrungen angeordnet, durch die der Haken eines Abhängedrahtes 220 greift, der zwecks Längenverstellbarkeit in eine Klemmfeder 211 gemäß Fig. 10 eingesetzt ist. Durch Zusammendrücken der federnden Schenkel der Klemmfeder 211 kann die Länge des Abhängehakens 220 stufenlos verstellt werden.In the vertical part of the ceiling profile 201 Bores arranged through which the hook of a suspension wire 220 engages, which is inserted into a clamping spring 211 according to FIG. 10 for the purpose of length adjustment. The length of the suspension hook 220 can be infinitely adjusted by compressing the resilient legs of the clamping spring 211.

Die andere Seite des Abhängehakens 220 ist mit dem abgebogenen Teil in eine Ösenschraube 250 eingehängt, die ihrerseits in einen in der Massivdecke 13 eingeschraubten Messingdübel 251 eingeschraubt ist.The other side of the suspension hook 220 is hung with the bent part in an eyebolt 250, which in turn is screwed into a brass dowel 251 screwed into the solid ceiling 13.

Bei Feuereinwirkung von der Unterseite 12 der abgehängten Decke her werden die im Zwischenraum zwischen der Massivdecke 13 und der abgehängten Decke angeordneten Deckenträger 11 lediglich gemäß der vorstehenden Beschreibung mit Hitzeeinwirkung beaufschlagt. Es wird also ein außerordentlich hohen Feuerhemmvermögen erzielt.When exposed to fire from the underside 12 of the suspended ceiling, the ceiling supports 11 arranged in the space between the solid ceiling 13 and the suspended ceiling are only subjected to the influence of heat as described above. An extraordinarily high fire retardancy is therefore achieved.

Ein anderes Anwendungsgebiet zeigt die Darstellung in Figur 11. Das dort gezeigte Mantelelement 15 dient zur vollflächigen Ummantelung von horizontalen oder vertikalen Trägern.Another area of application is shown in FIG. 11. The jacket element 15 shown there serves for the full-surface coating of horizontal or vertical supports.

Zur eingehenden Eerläuterung eines solchen Mantelelementes wird auf die diesbezügliche Offenbarung der deutschen Patentanmeldung P 31 17 580.5-25 verwiesen. Die dort stehende Offenbarung soll voll inhaltlich in die vorliegende Offenbarung aufgenommen werden und ist Gegenstand der vorliegenden Erfindung.For a detailed explanation of such a jacket element, reference is made to the relevant disclosure in German patent application P 31 17 580.5-25. The content of the disclosure contained therein is to be included in the present disclosure and is the subject of the present invention.

Die einzelnen Plattenelemente 16,17,18 sind jeweils an ihren Berührungsflächen über Leimschichten 5 mit der Reflexionsfolie 4 verbunden. Die Reflexionsfolie kann auch noch im Innenraum 30 des Mantelelementes 15 auf den in den Innenraum weisenden Flächen der Plattenelemente angeordnet sein.The individual plate elements 16, 17, 18 are each connected to the reflective film 4 at their contact surfaces via glue layers 5. The reflection film can also be arranged in the interior 30 of the jacket element 15 on the surfaces of the plate elements facing the interior.

Zusätzlich ist die Reflexionsfolie 4 auch noch auf der Außenseite der Plattenelemente angeordnet. Diese Außenseite wird noch zusätzlich durch einen Mantelbelag 31 abgedeckt, der aus einer dekorativen Kunststoffolie, einem Stoff oder einem anderen dekorativen Belag bestehen kann. Wichtig ist, daß Feuereinwirkung von der Außenseite des Mantelelementes 15 mit Sicherheit vom Innenraum 30 abgehalten wird. Hierzu sind die Plattenelemente 16,18 durch jeweils einen Gehrungsschnitt 29 voneinander getrennt, wobei der Gehrungsschnitt 29 in treppenförmige Hinterschneidungen 28 übergeht. Auf diese Weise wird ein luftdichter Abschluß der Plattenelemente 16,17,18,27 erreicht, zumal die Verbindungsflächen über Leimschichten 5 mit der Reflexionsfolie 4 bekleidet sind.In addition, the reflective film 4 is also arranged on the outside of the plate elements. This outside is additionally covered by a jacket covering 31, which can consist of a decorative plastic film, a fabric or another decorative covering. It is important that the effect of fire from the outside of the jacket element 15 is safely prevented from the interior 30. For this purpose, the plate elements 16, 18 are separated from one another by a miter cut 29, the miter cut 29 merging into step-shaped undercuts 28. In this way, an airtight seal of the plate elements 16, 17, 18, 27 is achieved, especially since the connecting surfaces are covered with the reflective film 4 via glue layers 5.

Das gesamte Mantelelement kann durch eine Verschraubung 33 zusammengehalten werden, wobei im Bereich des Schraubenkopfes eine Trennfuge 32 des Mantelbelages 31 angeordnet ist, damit der Kopf der Schraube von außen her zugänglich ist.The entire jacket element can be held together by a screw connection 33, a parting line 32 of the jacket covering 31 being arranged in the region of the screw head so that the head of the screw is accessible from the outside.
