Description

Die Erfindung betrifft ein Deckenelement für eine Brandschutz-Zwischendecke mit den Merkmalen des Oberbegriffes von Patentanspruch 1.The invention relates to a ceiling element for a fire protection false ceiling with the features of the preamble of claim 1.

Deckenelemente der genannten Art sind aus DE-U1-8912602 bekannt. Konkret handelt es sich bei dem besagten Deckenelement um eine Deckenplatte aus Mineralfasern und insbesondere um eine Langfeldplatte für freigespannte Wand zu Wand-Feuerschutzunterdecken in Fluren oder dergleichen Räumen. Sie umfaßt zwei Mineralfaserplatten unter Einschluß eines freien Luftraumes im Abstand und parallel zueinander und ist mit Hilfe zweier leistenförmiger Metallprofile zu einer einzigen Platteneinheit zusammengefaßt, wobei je ein Metallprofil entlang der fluchtend zueinander liegenden Längsseiten der Platteneinheit in Nuten gehalten ist. Ceiling elements of the type mentioned are known from DE-U1-8912602. Specifically, the said ceiling element is one Ceiling slab made of mineral fibers and especially around a long slab for exposed wall to wall fire protection ceilings in hallways or like spaces. It includes two mineral fiber plates with inclusion of a free air space at a distance and parallel to each other and is with Using two strip-shaped metal profiles to form a single panel unit summarized, each with a metal profile along the aligned mutually lying long sides of the plate unit is held in grooves.

Die Schmalseiten der Mineralfaserplatten sind durch Füllstücke aus Mineralfaser-Plattenmaterial verschlossen. Die Metallprofile sind ferner im Querschnitt so ausgebildet, daß sie sich von in die zugehörigen Nuten einsteckbaren, oberen und unteren Flanschen oder Randschenkeln jeweils C-förmig zur Profilmitte hin erstrecken, wobei sie - bezogen auf die Längskanten der Mineralfaserplatten - in Einwärtsrichtung eingezogen sind.The narrow sides of the mineral fiber boards are made of mineral fiber board material locked. The metal profiles are also in Cross-section designed so that they are in the associated grooves insertable, upper and lower flanges or edge legs each C-shaped towards the middle of the profile, whereby - based on the Longitudinal edges of the mineral fiber boards - drawn inwards are.

Aus der DE-U1-9107145 ist es bekannt, die metallischen Profilleisten teilweise abzudecken. Die Profilleisten sind dadurch zum Teil gegen einen unmittelbaren Feuerangriff geschützt und somit wärmetechnisch etwas isoliert. Der Wärmeübergang in den freien Luftspalt zwischen den beiden Mineralfaserplatten wird durch die besagten Maßnahmen erschwert. Ein optimaler Schutz der metallischen Profilleisten wird jedoch nicht erzielt, da wesentliche Teile der Profilleisten, die für die Tragfähigkeit wichtig sind, nach wie vor in der Trennungsfuge zweier benachbarter, plattenförmiger Deckenelemente ungeschützt liegen. Auch sind vor allem diejenigen Teile der metallischen Profilleisten einem wie bisher ungeschützten Wärmeangriff ausgesetzt, die sich besonders nah bei der Oberseite beziehungsweise bei der Unterseite der Deckenelemente befinden.From DE-U1-9107145 it is known the metallic profile strips partially cover. The profile strips are thus partially against you protected from direct fire attack and thus somewhat thermally isolated. The heat transfer into the free air gap between the two Mineral fiber boards are made more difficult by the measures mentioned. On However, optimal protection of the metallic profile strips is not achieved because essential parts of the profile strips that are important for the load-bearing capacity, still in the separation joint of two neighboring, plate-shaped Ceiling elements are exposed. Most of all, those are parts the metallic profile strips one as before unprotected Exposed to heat attack, which is particularly close to the top or at the bottom of the ceiling elements.

Der Erfindung liegt somit die Aufgabe zugrunde, Deckenelemente der genannten Art weiterhin zu optimieren, damit sie erhöhten Brandschutzanforderungen gerecht werden können. The invention is therefore based on the object of ceiling elements continue to optimize the type mentioned so that they increased Fire protection requirements can meet.

Zur Lösung dieser Aufgabe sieht die Erfindung mit den Merkmalen des kennzeichnenden Teiles von Patentanspruch 1 vor, daß die Profilleisten nach außen über ihre gesamte Höhe mit Hilfe von mindestens einem Abdeckstreifen aus einem schwer entflammbaren oder nicht brennbaren Werkstoff abgedeckt sind, wobei die Profilleisten zwischen den Randschenkeln einen ebenen Steg aufweisen und wobei die Platten einander zugewandte Kantenausnehmungen derart aufweisen, daß die Abdeckstreifen mit ihrer außen liegenden Oberfläche mit den freien Randflächen der oberen bzw. unteren Platte fluchten.To achieve this object, the invention provides with the features of characterizing part of claim 1 before that the profile strips outwards over their entire height with the help of at least one Cover strips from a flame-retardant or non-flammable Material are covered, the profile strips between the Edge legs have a flat web and the plates have mutually facing edge recesses such that the Cover strips with their outer surface with the free Align the upper and lower plates.

Mit Hilfe der besagten Merkmale sind die metallischen Teile optimal und somit besser als bisher gegen hohe Temperaturen im Fugenbereich geschützt mit der Folge, daß die volle tragende Funktion der Profilleisten bei einem Brandangriff von oben oder auch bei einem Brandangriff von unten länger als bisher erhalten bleibt.With the help of said features, the metallic parts are optimal and thus better than before against high temperatures in the joint area protected with the consequence that the full load-bearing function of the profile strips in the event of a fire attack from above or in the event of a fire attack from remains below longer than before.
