Description

Die Erfindung betrifft ein Formteil, insbesondere kastenförmiges oder topfförmiges Formteil, für Brandschutzzwecke mit einer vorderseitigen Öffnung zur Anordnung von Installationsteilen oder elektrotechnischen Bauteilen, insbesondere einer Leuchte, wobei das Formteil aus einem formstabilen Gehäuse aus nichtbrennbarem Material, insbesondere Metallblech, das innenseitig ein eine Dämmschicht bildendes Material aufweist, welches unter Einwirkung von Hitze und/oder Feuer aufbläht und/oder eine Karbonsperrschicht bildet.The invention relates to a molded part, in particular box-shaped or cup-shaped molded part, for fire protection purposes with a front opening for the arrangement of installation parts or electrical components, in particular a lamp, wherein the molded part of a dimensionally stable housing made of non-combustible material, in particular sheet metal, the inside forming an insulating layer Material which inflates under the action of heat and / or fire and / or forms a Karbonsperrschicht.

Ein derartiges Formteil ist aus der EP-A-0908668 bekannt.Such a molding is from the EP-A-0908668 known.

Der Erfindung liegt die Aufgabe zu Grunde, ein Formteil gattungsgemäßer Art zu schaffen, welches als komplette Brandschutzeinheit eingesetzt werden kann, einen großen Einbauraum für beliebige Installationsteile oder elektrische Bauteile zur Verfügung stellt, insbesondere für eine großdimensionierte elektrische Leuchteinheit, wobei das Formteil kostengünstig und relativ leichtgewichtig ausgebildet sein soll und eine sichere Brandabschottung ermöglicht.The invention is based on the object to provide a molded part of the generic type, which can be used as a complete fire protection unit, a large installation space for any installation parts or electrical components available, especially for a large-sized electrical lighting unit, the molding cost and relatively lightweight should be trained and allows a safe fire barrier.

Zur Lösung dieser Aufgabe wird vorgeschlagen, dass zwischen der Dämmschicht und der Gehäusewandung eine Schicht aus Mineralwolle, insbesondere Steinwolle, angeordnet ist.To solve this problem it is proposed that a layer of mineral wool, especially rock wool, is arranged between the insulating layer and the housing wall.

Das Gehäuse kann entsprechend seinem Einsatzzweck ein großdimensioniertes Blechgehäuse mit einseitiger offener Mündung sein, wobei das Gehäuse vorzugsweise quaderförmig ausgebildet ist. Dadurch, dass als Brandschutzmaterial einerseits eine Mineralwolleschicht bzw. Steinwolleschicht und andererseits eine diese Mineralwolle- oder Steinwolle-Schicht abdeckende Schicht aus Material aufweist, welches unter Einwirkung von Hitze und/oder Feuer aufbläht, wird ein wesentlicher Vorteil erreicht. Durch die Kombination dieser beiden Materialien ist bei geringer Wandstärke der nach Art eines Sandwiches aufgebauten Schicht eine optimale Wärmeisolierung erreicht. Zusätzlich wird das Eigengewicht relativ gering gehalten, weil durch die Materialkombination ein geringeres Eigengewicht erreicht wird; als in dem Fall, dass die Materialschicht lediglich aus dem eine Dämmschicht bildenden, unter Einwirkung von Hitze oder Feuer aufblähbaren Material bestünde. Die Herstellungskosten sind minimiert, weil das relativ teure, die Dämmschicht bildende aufblähbare Material nur in relativ geringer Wandstärke eingesetzt werden muss, während das kostengünstigere Mineralwolle- oder Steinwollematerial ihrem Einsatzzweck entsprechend dimensioniert eingesetzt werden kann. Zudem wird durch diese Kombination die Gesamtwandstärke relativ gering gehalten, so dass der Einbauraum, der im Gehäuse nach Einbringen der Materialschichten zur Verfügung steht, relativ groß gehalten ist. Bei einem Aufbau allein mit Mineralwolle oder Steinwolle wäre die Wandschicht erheblich stärker, so dass der Einbauraum im Gehäuse erheblich eingeschränkt wäre.The housing may be according to its purpose a large-sized sheet metal housing with one-sided open mouth, the housing is preferably formed cuboid. The fact that the fire protection material on the one hand a mineral wool layer or rock wool layer and on the other hand has a mineral wool or rock wool layer covering layer of material which inflates under the action of heat and / or fire, a significant advantage is achieved. Due to the combination of these two materials, optimum thermal insulation is achieved with a small wall thickness of the sandwich-type layer. In addition, the weight is kept relatively low, because a lower weight is achieved by the combination of materials; as in the case that the material layer only from the insulating layer forming, under the action of heat or fire inflatable material would consist. The production costs are minimized because the relatively expensive, the insulating layer forming inflatable material must be used only in relatively small wall thickness, while the cost-effective mineral wool or rock wool material can be used according to their intended use dimensioned. In addition, this combination is the Total wall thickness kept relatively low, so that the installation space, which is available in the housing after introducing the material layers, is kept relatively large. In a construction with mineral wool or rock wool alone, the wall layer would be considerably stronger, so that the installation space would be considerably restricted in the housing.

Aus der DE 93 18 416 U1 ist die Verwendung von auf Basis von Mineralwolle gebildeten Platten zur Wärmeisolierung bekannt.From the DE 93 18 416 U1 it is known to use mineral wool-based thermal insulation panels.

Bevorzugt ist zudem bei einem Formteil in Form eines mit einem Bodenteil und einem Wandteil bestehenden Gehäuses vorgesehen, dass die Schicht aus Mineralwolle durch plattenartige Teile aus Mineralwolle gebildet ist, die in Form eines Bodenteils und in Form von Wandteilen in das Gehäuse eingebracht sind und durch das die Dämmschicht bildende Material lagegesichert gehalten sind.Preference is also provided in a molding in the form of a housing provided with a bottom part and a wall part that the layer of mineral wool is formed by plate-like parts of mineral wool, which are introduced in the form of a bottom part and in the form of wall parts in the housing and through the the insulating layer forming material are kept secure in position.

Durch diese Ausbildung ist es möglich, zunächst die Schicht aus Mineralwolle in der Gehäuse einzubringen, in- dem die plattenartigen Teile in das Gehäuse eingebracht werden und allein durch ihre Zuschnittsform in einer Vormontage-Position gehalten sind. Anschließend kann das die Dämmschicht bildende Material aufgebracht werden, wodurch die endgültige Lagesicherung der Teile zueinander erreicht wird.With this design, it is possible to first introduce the layer of mineral wool in the housing, in which the plate-like parts are introduced into the housing and are held solely by their blank form in a pre-assembly position. Subsequently, the insulating layer forming material can be applied, whereby the final position assurance of the parts is achieved to each other.

Insbesondere ist für die Lagesicherung der Schichten innerhalb des Gehäuses vorgesehen, dass das Gehäuse einen Mündungsrand aufweist und im Bereich des Mündungsrandes des Gehäuses ein von Mineralwolle freier Rand vorgesehen ist, der durch das die Dämmschicht bildende Material gefüllt ist, welches unmittelbar mit dem Rand des Gehäuses verbunden, insbesondere verklebt, ist.In particular, it is provided for the position assurance of the layers within the housing that the housing has a mouth edge and a mineral wool-free edge is provided in the region of the mouth edge of the housing, which is filled by the insulating layer forming material, which is directly connected to the edge of the housing, in particular glued.

Dadurch, dass die Frontkante mit dem die Dämmschicht bildenden Material übergossen ist, wird erreicht, dass im Brandfall der Raumabschluss gewährt bleibt. Die übergossene Frontkante wirkt wie eine nachschäumende Dichtlippe und stellt den Raumabschluss sicher. Darüberhinaus wird durch das die Dämmschicht bildende Material das Mineralwolleplattenmaterial an der Innenseite des Metallgehäuses fixiert.The fact that the front edge is doused with the material forming the insulating layer, ensures that in case of fire, the room closure is granted. The over-molded front edge acts like a nachschäumende sealing lip and ensures the space closure. Moreover, the mineral wool plate material is fixed to the inside of the metal case by the material forming the insulating layer.

Das die Dämmschicht bildende Material wird bei der Herstellung als gießfähiges Material auf die Mineralwollschicht und den Gehäuserand aufgetragen.The material forming the insulating layer is applied to the mineral wool layer and the edge of the shell during production as a castable material.

Gegenstand der Erfindung ist ferner eine Unterdecke für Brandschutzzwecke. Erfindungsgemäß besteht diese aus einem einlagig oder vorzugsweise mehrlagig ausgebildeten Plattenelement aus feuer- und hitzebeständigem Material, beispielsweise Gipskartonplatten, einer das Plattenelement haltenden Tragkonstruktion mit zueinander kreuzend verlegten ersten und zweiten Metalltragprofilen, an denen die Bestandteile des Plattenelementes in geeigneter Form befestigt sind. Ferner sind bandartige oder ankerartige Befestigungsteile vorgesehen, die einerseits vorzugsweise an den ersten Metalltragprofilen befestigt sind und andererseits an der Gebäudedecke oder dergleichen Tragteilen befestigbar sind, so dass die Konstruktion einer untergehängten Decke realisiert ist. Das Plattenelement weist mindestens eine Öffnung auf, die von einem Formteil nach einem der Ansprüche 1 bis 3 überdeckt ist. Das Formteil stützt sich rückseitig des Plattenelementes an diesem ab. Rückseitig des Plattenelementes sind neben der Öffnung und neben den Rändern des Formteils, welche die Öffnung überdeckt, zwei zueinander parallele dritte Metalltragprofile angeordnet, die mit zu diesen kreuzend verlaufenden ersten Metalltragprofilen oder verbunden sind, oder es ist mindestens ein drittes Metalltragprofil angeordnet, das mit einem ersten oder zweiten Metalltragprofil verbunden ist, und mit Abstand zu einem ersten oder zweiten Metallprofil parallel zu diesem ausgerichtet ist, wobei die dritten Tragprofile oder die die Öffnung seitlich umgebenden Profile, nämlich ein drittes Tragprofil und ein dazu parallel verlaufendes erstes oder zweites Metallprofil zusätzlich mittels Befestigungsmitteln an dem Plattenelement befestigt sind und der Mündungsrand des das Formteil bildenden Gehäuses ist mittels Befestigungsmitteln an einem jeweils benachbarten Schenkel eines ersten, zweiten oder dritten Metalltragprofiles befestigt.The invention also relates to a false ceiling for fire protection purposes. According to the invention this consists of a single-layer or preferably multi-layered plate member made of fire and heat resistant material, such as plasterboard, a support member holding the plate member with intersecting laid first and second metal support profiles to which the components of the plate member are secured in a suitable form. Furthermore, band-like or anchor-like fastening parts are provided, which are preferably fastened on the one hand to the first metal support profiles and on the other hand can be fastened to the building ceiling or similar supporting parts, so that the construction of a suspended ceiling is realized. The plate element has at least one opening, which is covered by a molding according to one of claims 1 to 3. The molding supports on the back of the plate element at this from. Rear side of the plate member are adjacent to the opening and adjacent to the edges of the molding, which covers the opening, two mutually parallel third metal support profiles, which are connected to these crossing first metal support profiles, or at least a third metal support profile is arranged with a first or second metal support profile is connected, and is aligned at a distance to a first or second metal profile parallel to this, wherein the third support profiles or laterally surrounding the opening profiles, namely a third support profile and a parallel thereto first or second metal profile in addition by means of fasteners are attached to the plate member and the mouth edge of the molding forming housing is fastened by means of fasteners to a respective adjacent leg of a first, second or third metal support profile.

Bevorzugt ist zudem vorgesehen, dass zwischen dem im Bereich des Mündungsrandes des Gehäuses vorgesehenen, die Dämmschicht bildenden Material und dem diese untergreifenden Bereich des Plattenelementes eine umlaufende Raupe aus Brandschutzkitt aufgebracht ist.Preferably, it is also provided that between the provided in the region of the mouth edge of the housing, the insulating layer forming material and this under cross-section of the plate member, a circumferential bead of fire-resistant putty is applied.

Des Weiteren ist bevorzugt vorgesehen, dass an den Seitenwänden des Gehäuses Haltewinkel befestigt sind, die über Schenkel oder Stege der dritten Metalltragprofile greifen.Furthermore, it is preferably provided that on the side walls of the housing brackets are attached, which engage over legs or webs of the third metal support profiles.

Zudem ist bevorzugt vorgesehen, dass an den ersten oder zweiten Metalltragprofilen bandartige oder ankerartige Befestigungselemente angeordnet sind, und zwar im neben der Wandung des Gehäuses befindlichen Bereich der ersten Metalltragprofile, die an der Gebäudedecke oder dergleichen Tragteilen befestigt sind.In addition, it is preferably provided that band-like or anchor-like fastening elements are arranged on the first or second metal support profiles, specifically in the area of the first metal support profiles adjacent to the wall of the housing, which are fastened to the building ceiling or similar supporting parts.

Besonders ist bevorzugt, dass die Unterkante des Gehäuses mit der Anlagefläche der ersten, zweiten und/oder dritten Metalltragprofile an dem Plattenelement fluchtet.It is particularly preferred that the lower edge of the housing is aligned with the contact surface of the first, second and / or third metal support profiles on the plate member.

Zudem kann vorgesehen sein, dass als Befestigungsmittel Schrauben, insbesondere Blechschrauben, angeordnet sind.In addition, it can be provided that screws, in particular sheet-metal screws, are arranged as fastening means.

Bei der erfindungsgemäßen Konstruktion wird zunächst die Unterdecke in herkömmlicher Art aufgebaut, wobei die ersten und zweiten Metalltragprofile über Anker oder dergleichen an der Decke oder dergleichen Tragteil befestigt werden und die Plattenelemente an diesen Profilen fixiert werden. Über der Öffnung, die für die Installation einer Leuchte oder dergleichen vorgesehen ist, wird das Formteil positioniert. Dabei ist nahe zweier zueinander paralleler Randkanten der rechteckigen Öffnung die Anordnung von dritten Metalltragprofilen vorgesehen, die die ersten Tragprofile kreuzen und im Kreuzungspunkt an diesen befestigt sind. Vorzugsweise wird das Gehäuse mit seiner Mündung niveaugleich zur Unterkante der Befestigungsprofile (dritte Metalltragprofile) ausgerichtet. Zusätzlich wird das Gehäuse mittels jeweils zwei an seinen Seiten befestigten, beispielsweise angeschraubten oder angepunkteten Winkeln auf die zusätzlichen dritten Metalltragprofile gehängt. Um die niveaugleiche Ausrichtung des Gehäuses zu fixieren, werden Blechschrauben seitlich von innen oder außen verschraubt, so dass eine Verbindung des Gehäuses mit dem dritten Metalltragprofil hergestellt ist. Das dritte Metalltragprofil ist zusätzlich durch Schrauben an den Plattenelementen befestigt, die die Plattenelemente durchdringen, so dass eine feste Fixierung des gesamten fertigen Bauteiles an dem Plattenelement gewährleistet ist. Es ist damit nicht möglich, das Formteil zu verschieben oder hochzudrücken. Die Frontkante des Gehäuses ist mit dem die Dämmschicht bildenden Material übergossen, so dass im Brandfall der Raumabschluss gewährt bleibt. Die übergossene Frontkante wirkt wie eine nachschäumende Dichtlippe und stellt den Raumabschluss sicher. Die umlaufende Raupe aus Brandschutzkitt unterstützt diesen Vorgang und bewirkt zusätzlich eine Verklebung der Teile mit dem Plattenmaterial.In the construction according to the invention, first, the sub-ceiling is constructed in a conventional manner, wherein the first and second metal support profiles are attached via anchors or the like to the ceiling or the like support member and the plate elements are fixed to these profiles. Above the opening, which is provided for the installation of a lamp or the like, the molding is positioned. In this case, the arrangement of third metal support profiles is provided near two mutually parallel edges of the rectangular opening, which intersect the first support profiles and are secured at the intersection point to this. Preferably, the housing with its mouth is level with the bottom edge of the mounting profiles (third metal support profiles) aligned. In addition, the housing is hung by means of two each attached to its sides, for example screwed or dotted angles on the additional third metal support profiles. In order to fix the level alignment of the housing, tapping screws are screwed laterally from the inside or outside, so that a connection of the housing is made to the third metal support profile. The third metal support profile is additionally fastened by screws to the plate elements, which penetrate the plate elements, so that a firm fixation of the entire finished component is ensured on the plate member. It is thus not possible to move the molding or push up. The front edge of the housing is covered with the insulating layer forming material, so that in case of fire, the space closure is granted. The over-molded front edge acts like a nachschäumende sealing lip and ensures the space closure. The encircling caterpillar made of fire-retardant cement supports this process and additionally causes the parts to stick to the plate material.

Es ist möglich, die ersten und zweiten Metalltragprofile in einer gemeinsamen Ebene anzuordnen und miteinander zu verbinden oder die Metalltragprofile übereinander in zwei Ebenen anzuordnen und im Kreuzungsbereich zu verbinden.It is possible to arrange the first and second metal support profiles in a common plane and to connect them together or to arrange the metal support profiles on top of each other in two levels and to connect in the crossing area.
