Boundary regions of the plates are curved inward such that the regions surround a front side surface of the section. Adjacent front side surfaces of the section and front sides of the protection units are designed in a planar manner. Local connection units are fixed at the regions, and act together with a connecting unit (14) of the protection units, so that the protection units are secured together against a lateral displacement.

Description

Die Erfindung betrifft eine Brandschutzvorrichtung, insbesondere Brandschutztor, mit mehreren plattenförmigen Brandschutzelementen, die jeweils zwei Deckplatten aufweisen, zwischen welchen zumindest eine Füllschicht aus einem feuerfesten Material aufgenommen ist, wobei die Randbereiche der Deckplatten derart zueinander nach innen gebogen sind, dass die Randbereiche ohne einander zu berühren zumindest eine stirnseitige Fläche der Füllschicht einfassen.The invention relates to a fire protection device, in particular fire protection door, with a plurality of plate-shaped fire protection elements, each having two cover plates, between which at least one filling layer is received from a refractory material, wherein the edge regions of the cover plates are bent inwardly toward each other such that the edge regions without each other touch border at least one frontal surface of the filling layer.

Bei derartigen aus mehreren Brandschutzelementen bestehenden Brandschutzvorrichtungen, insbesondere Brandschutztoren, soll gewährleistet sein, dass im Brandfall die Elemente in ihrer vorbestimmten zueinander ausgerichteten Stellung zueinander verbleiben, d.h. es soll eine Spaltbildung zwischen den Elementen vermieden werden, so dass ein Übertritt eines Brandes von einem Brandherd möglichst vermieden werden kann. Hiezu sind aus dem Stand der Technik verschiedenste Verbindungen bzw. Befestigungen zwischen den Brandschutzelementen bekannt.In such consisting of several fire protection elements fire protection devices, in particular fire doors, it should be ensured that in the event of fire, the elements remain in their predetermined aligned position to each other, i. It should be avoided a gap formation between the elements, so that a transfer of a fire from a fire can be avoided as possible. For this purpose, various connections or fastenings between the fire protection elements are known from the prior art.

Aus der DE 34 23 322 A1 ist ein Brandschutztor bekannt, dessen Torblatt aus einer Mehrzahl von nebeneinander angeordneten und miteinander verbundenen Torelementen besteht, an deren seitlichen Stirnflächen die Schalen zur Ausbildung von Aufnahmeöffnungen speziell gebogen sind. Dabei weisen die Schalen an den Rändern U-förmige Umbiegungen auf. Zudem sind an den Stirnflächen jeweils Abschlussbleche vorgesehen. Um einen seitlichen Versatz benachbarter Torelemente zu verhindern, sind auf den U-förmigen Umbiegungen U-profilierte Leisten geschoben bzw. gepresst, die sich über die gesamte Höhe des Torelements erstrecken.From the DE 34 23 322 A1 a fire door is known whose door leaf consists of a plurality of juxtaposed and interconnected gate elements, at the lateral end faces of the shells are specially bent to form receiving openings. In this case, the shells on the edges of U-shaped bends. In addition, each end plates are provided on the end faces. In order to prevent a lateral offset of adjacent door elements, U-profiled strips are pushed or pressed on the U-shaped bends, which extend over the entire height of the gate element.

Aus der DE 26 57 141 ist eine Feuerschutztüre bzw. ein Feuerschutztor bekannt, bei welchem die Kanten benachbarter Brandschutzelemente ineinander greifende Falzprofile nach Art einer Nut-/Federverbindung aufweisen. Hierdurch soll möglichst eine Spaltbildung durch Verwerfungen zwischen benachbarten Brandschutzelementen verhindert werden. Zudem weisen die hierin gezeigten Brandschutzelemente im Wesentlichen in horizontaler Richtung verlaufende stangenförmige Zuganker auf, welche an den Außenseiten der Feuerschutztüre befestigt sind, so dass die einzelnen Gasbetonplatten zueinander verspannt werden können. Nachteilig ist hierbei insbesondere der konstruktiv hohe Aufwand für die Ausbildung derartiger Nut-/Federverbindungen.From the DE 26 57 141 a fire door or a fire door is known in which the edges of adjacent fire protection elements have interlocking rabbet profiles in the manner of a tongue and groove connection. As a result, as far as possible a gap formation by warping between adjacent fire protection elements should be prevented. In addition, the fire protection elements shown herein have substantially in the horizontal direction bar-shaped tie rods, which on the Outer sides of the fire door are attached, so that the individual gas concrete slabs can be clamped to each other. The disadvantage here is in particular the structurally high cost of training such tongue and groove connections.

Weiters ist aus der DE 21 44 444 A eine Fassadenwand bestehend aus mehreren Elementen bekannt, bei welchen ein spezieller im Wesentlichen U-förmig gebogener Rahmen aus einem Stahlblech vorgesehen ist, um die ebenfalls speziell ausgebildeten Randbereiche benachbarter Elemente miteinander zu verbinden. Auch hierbei ist demzufolge ein hoher konstruktiver Aufwand zur Ausbildung der speziellen ineinander greifenden Profile erforderlich.Furthermore, is from the DE 21 44 444 A a façade wall consisting of several elements known, in which a special substantially U-shaped bent frame is provided from a steel sheet to connect the also specially trained edge regions of adjacent elements together. Again, therefore, a high design effort to form the special interlocking profiles is required.

Weiters ist aus der DE 44 43 857 eine Brandschutzwand bekannt, wobei die Randbereiche von Deckplatten zum Einfassen einer Füllschicht nach innen gebogen sind ohne einander zu berühren und benachbarte Brandschutzelemente unterschiedliche Biegungen aufweisen, so dass die benachbarten Brandschutzelemente wiederum in der Art einer Nut-/Federverbindung ineinander gesteckt werden können. Vergleichbare Nut-/Federverbindungen, um eine Spaltbildung zwischen benachbarten Brandschutzelementen zu vermeiden, sind zudem auch noch aus der DE 86 05 369 U , DE 195 26 550 A , EP 1 207 239 A , JP 9-137521 , JP 9-72021 , JP 2-43034 bekannt.Furthermore, is from the DE 44 43 857 a fire protection wall is known, wherein the edge regions of cover plates are bent to enclose a filling layer inwardly without touching each other and adjacent fire protection elements have different bends, so that the adjacent fire protection elements in turn can be inserted into each other in the manner of a tongue and groove connection. Comparable tongue and groove joints, to avoid a gap formation between adjacent fire protection elements, are also still from the DE 86 05 369 U . DE 195 26 550 A . EP 1 207 239 A . JP 9-137521 . JP 9-72021 . JP 2-43034 known.

Ziel der vorliegenden Erfindung war es demzufolge eine aus mehreren plattenförmigen Brandschutzelementen bestehende Brandschutzvorrichtung zu schaffen, welche einfach und kostengünstig herzustellen ist, und bei welcher dennoch eine Spaltbildung zwischen den Brandschutzelementen im Brandfall zuverlässig verhindert werden kann.The aim of the present invention was therefore to provide a fire protection device consisting of several plate-shaped fire protection elements, which is simple and inexpensive to manufacture, and in which nevertheless a gap formation between the fire protection elements in case of fire can be reliably prevented.

Erfindungsgemäß wird dies dadurch erzielt, dass die aneinander angrenzenden stirnseitigen Flächen der Füllschichten sowie die Stirnseiten der Brandschutzelemente im Wesentlichen plan ausgebildet sind und an den die planen Flächen einfassenden Randbereichen in Bereichen, in welchen die Gefahr einer Spaltbildung besteht, lokal Verbindungselemente befestigt sind, die jeweils mit einem Verbindungselement eines benachbarten Brandschutzelements zusammenwirken, so dass die Brandschutzelemente zumindest gegen einen seitlichen Versatz zueinander gesichert sind. Durch die im Wesentlichen plane Ausgestaltung der stirnseitigen Flächen der Füllschicht können herkömmliche quaderförmige Brandschutzelemente verwendet werden, ohne dass eine spezielle Ausgestaltung von ineinander greifenden Randprofilen erforderlich wäre. An diesen im Wesentlichen planen stirnseitigen Flächen ist sodann ein Verbindungselement bedarfsweise befestigt, welches mit dem Verbindungselement einer benachbarten Brandschutzwand zusammenwirkt, so dass zur Vermeidung von Spaltbildungen zumindest ein seitlicher Versatz der benachbarten Brandschutzelemente zueinander zuverlässig verhindert wird. Die Anordnung derartiger Verbindungselemente kann hierbei bedarfsweise je nach Abhängigkeit der Höhe der Brandschutzelemente bzw. Aussparungen für Fenster bzw. Türen in der Brandschutzvorrichtung, d.h. in jenen Bereichen, in welchen eine Spaltbildung wahrscheinlich ist, gewählt werden. Hierdurch ergibt sich ein kostengünstiges und zudem einfaches Verbindungssystem, bei welchem zuverlässig eine Spaltbildung zwischen den Brandschutzelementen durch die zusammenwirkenden Verbindungselemente verhindert werden kann.According to the invention this is achieved in that the adjoining end faces of the filling layers and the end faces of the fire protection elements are substantially planar and on the planar surfaces bordering the areas in which there is a risk of gap formation, local fasteners are attached, each interact with a connecting element of an adjacent fire protection element, so that the fire protection elements are secured to each other at least against a lateral offset. By the substantially planar configuration of the frontal surfaces of the filling layer conventional cuboid fire protection elements can be used without a special design of interlocking edge profiles would be required. At these essentially planar end faces, a connecting element is then fastened as required, which cooperates with the connecting element of an adjacent fire protection wall, so that at least one lateral offset of the adjacent fire protection elements is reliably prevented from each other to avoid gap formation. The arrangement of such fasteners may in this case, if necessary, depending on the dependence of the height of the fire protection elements or recesses for windows or doors in the fire protection device, ie in those areas in which a gap is likely to be selected. This results in a cost-effective and also simple connection system, in which reliably a gap formation between the fire protection elements can be prevented by the cooperating connecting elements.

Zudem wird dadurch, dass die Deckplatten der Brandschutzelemente miteinander nicht in Berührung stehen, zuverlässig ein Wärmeübertritt von einer inneren dem Brandherd zugewandten Deckplatte zu der äußeren vom Brandherd abgewandten Deckplatte vermieden.In addition, the fact that the cover plates of the fire protection elements are not in contact with each other, reliably prevents heat from an inner facing the fire cover plate to the outer facing away from the fire cover plate.

Wenn das Verbindungselement randseitige Befestigungsöffnungen zur Verbindung mit den Randbereichen der Deckplatten sowie zumindest eine vorzugsweise mittige Öffnung zur Aufnahme eines Verbindungsteils aufweist, ergibt sich eine einfache zuverlässige Befestigung der Verbindungselemente an den gebogenen Randbereichen der Deckplatten. Zudem kann durch die vorzugsweise mittige Öffnung zur Aufnahme eines Verbindungsteils auf einfache Weise eine formschlüssige Verbindung zwischen benachbarten Verbindungselementen hergestellt werden, so dass ein seitlicher Versatz zwischen den Brandschutzelementen verhindert wird.If the connecting element edge-side mounting holes for connection to the edge regions of the cover plates and at least one preferably central opening for receiving a connecting part, results in a simple reliable attachment of the connecting elements to the curved edge regions of the cover plates. In addition, through the preferably central opening for receiving a connecting part in a simple manner, a positive connection between adjacent connecting elements are produced, so that a lateral offset between the fire protection elements is prevented.

Um zwischen den Verbindungselementen auf einfache Weise eine formschlüssige Verbindung herzustellen, ist es günstig, wenn als Verbindungsteil eine Stange, insbesondere mit einem zumindest endseitigen Gewinde, vorgesehen ist. Sofern die Stange als Gewindestange ausgebildet ist, können die über die Stange formschlüssig miteinander verbundenen Brandschutzelemente zudem auf einfache Weise kraftschlüssig miteinander verbunden werden.In order to produce a positive connection between the connecting elements in a simple manner, it is favorable if a rod, in particular with an at least end-side thread, is provided as the connecting part. Unless the rod is a threaded rod is formed, the over the rod positively connected with each other fire protection elements can also be connected to each other in a simple manner non-positively.

Alternativ zu einer durch Aufnahmeöffnungen in den Verbindungsteilen hindurch gesteckte Stange ist es hinsichtlich einer formschlüssigen Verbindung zwischen benachbarten Verbindungselementen ebenfalls denkbar, dass als Verbindungsteil ein mit einem Verbindungselement fest verbundener Bolzen vorgesehen ist. Mit einem derartigen einen Bolzen tragenden Verbindungselement kann auf einfache Weise eine formschlüssige Verbindung mit einem benachbarten eine Aufnahmeöffnung für den Bolzen aufweisenden Verbindungselement hergestellt werden.As an alternative to a rod inserted through receiving openings in the connecting parts, it is likewise conceivable, with regard to a positive connection between adjacent connecting elements, that a bolt fixedly connected to a connecting element is provided as the connecting part. With such a bolt carrying a connecting element can be made in a simple manner a positive connection with an adjacent a receiving opening for the bolt having connecting element.

Um eine Wärmeübertragung zwischen den beiden Deckplatten eines Brandschutzelements über das Verbindungselement nach Möglichkeit zu verhindern, ist es günstig, wenn das Verbindungselement unter Zwischenlage eines Brandschutzlaminats an den Randbereichen der metallischen Deckplatten befestigt ist.In order to prevent heat transfer between the two cover plates of a fire protection element via the connecting element as far as possible, it is advantageous if the connecting element is fastened with the interposition of a fire-resistant laminate to the edge regions of the metallic cover plates.

Weiters ist es günstig, um eine Wärmeübertragung über die Verbindungselemente möglichst zu vermeiden, wenn das Verbindungselement zwischen der Füllschicht und den Randbereichen der Deckplatten angeordnet ist.Furthermore, it is favorable to avoid heat transfer via the connecting elements as far as possible when the connecting element is arranged between the filling layer and the edge regions of the cover plates.

Um weiters eine Spaltbildung zwischen den Brandschutzelementen insbesondere im oberen und im unteren Randbereich der Brandschutzvorrichtung zu vermeiden, ist es vorteilhaft, wenn in einem oberen bzw. unteren Endabschnitt der im Wesentlichen vertikal angeordneten Brandschutzelemente jeweils ein im Wesentlichen horizontal angeordnetes C-, U- oder Hohlprofil vorgesehen ist, in welche zumindest ein sich über zumindest zwei Brandschutzelemente erstreckendes lineares Verbindungselement eingeführt ist.In order to further avoid a gap formation between the fire protection elements, in particular in the upper and in the lower edge region of the fire protection device, it is advantageous if in each case a substantially horizontally arranged C, U or hollow profile in an upper or lower end section of the substantially vertically arranged fire protection elements is provided, in which at least one is introduced over at least two fire protection elements extending linear connection element.

Hierbei ist es hinsichtlich einer kraftschlüssigen Verbindung zwischen den Brandschutzelementen vorteilhaft, wenn in den im oberen und/oder unteren Endabschnitt angeordneten Hohlprofilen eine sich über mehrere Brandschutzelemente erstreckende Gewindestange mit endseitigen Aufnahmeteilen aufgenommen ist.In this connection, it is advantageous with regard to a frictional connection between the fire protection elements if a threaded rod extending over a plurality of fire protection elements is received in the hollow profiles arranged in the upper and / or lower end section with end-side receiving parts.

Wenn insbesondere benachbart einer Aussparung in einem Brandschutzelement zumindest ein Verbindungselement zur Befestigung eines ein lineares Verbindungselement aufnehmenden C-, U- oder Hohlprofils vorgesehen ist, kann die Spaltbildung insbesondere auch in einem Bereich benachbart einer Aussparung zuverlässig vermieden werden.If, in particular adjacent to a recess in a fire protection element, at least one connecting element is provided for fastening a linear connecting element receiving C, U or hollow profile, the gap formation can be reliably avoided especially in a region adjacent to a recess.

Hinsichtlich einer einfachen, zuverlässigen Befestigung des Verbindungselements am Brandschutzelement ist es günstig, wenn das Verbindungselement über eine Nietverbindung mit dem Brandschutzelement verbunden ist.With regard to a simple, reliable attachment of the connecting element on the fire protection element, it is advantageous if the connecting element is connected via a riveted joint with the fire protection element.

In Fig. 1 ist ein Brandschutztor 1 ersichtlich, welches mehrere vertikal angeordnete Brandschutzelemente 2 aufweist, deren plane, schmalseitige Stirnflächen 3 Stoß an Stoß aneinander angeordnet sind.In Fig. 1, a fire door 1 can be seen, which has a plurality of vertically arranged fire protection elements 2, the flat, narrow-sided end faces 3 are arranged abutting each other.

Wie insbesondere aus Fig. 2 ersichtlich, weisen die Brandschutzelemente 2 jeweils zwei metallische Deckplatten 4 zur Ausbildung einer Blechschale auf, zwischen welcher eine Füllschicht 5 aus einem feuerfesten Material, z.B. aus Miprotec L ® oder dgl., aufgenommen ist. Die aneinander angrenzenden stirnseitigen Schmalflächen der Brandschutzelemente 2 sind hierbei im Wesentlichen plan ausgebildet, wobei die metallischen Deckplatten 4 Randbereiche 4' aufweisen, die zueinander nach innen gebogen sind, so dass die Füllschicht 5 von den metallischen Deckplatten 4 eingefasst wird.As can be seen in particular from Fig. 2, the fire protection elements 2 each have two metallic cover plates 4 for forming a sheet metal shell, between which a filling layer 5 made of a refractory material, e.g. from Miprotec L® or the like., Was added. The adjoining frontal narrow surfaces of the fire protection elements 2 are in this case substantially planar, wherein the metallic cover plates 4 edge portions 4 ', which are bent inwardly towards each other, so that the filling layer 5 is bordered by the metallic cover plates 4.

Um eine Wärmeübertragung zwischen den beiden Deckplatten 4 zu vermeiden, sind die Randbereiche 4' der inneren und äußeren Blechschalen 4 voneinander getrennt angeordnet. Zudem ist zwischen dem Füllschichtmaterial 5 und den Randbereichen 4 ein Brandschutzstreifen 6 vorgesehen, der einerseits zwecks einer thermischen Trennung zwischen den beiden Deckplatten 4 vorgesehen ist, und zudem aus einem aufquellenden Material, z.B. Palusol®, besteht, so dass ein etwaiger Spalt zwischen benachbarten Brandschutzelementen 2 im Brandfall möglichst abgedichtet wird.In order to avoid heat transfer between the two cover plates 4, the edge regions 4 'of the inner and outer sheet metal shells 4 are arranged separately from each other. In addition, a fire protection strip 6 is provided between the filling layer material 5 and the edge regions 4, which is provided on the one hand for the purpose of thermal separation between the two cover plates 4, and also of a swelling material, e.g. Palusol®, so that any gap between adjacent fire protection elements 2 is sealed as possible in case of fire.

Die Brandschutzelemente 2 sind hierbei - wie insbesondere in den Fig. 7 und 8 ersichtlich - im oberen bzw. unteren Endbereich kraft- sowie formschlüssig miteinander verbunden. Hierzu weist jedes Brandschutzelement 2 in einem oberen bzw. unteren Endbereich ein im Wesentlichen viereckiges Hohlprofil 7 auf, in welchem ein sich über die gesamte Länge des Brandschutztors 1 erstreckendes Linearelement bzw. Verbindungsteil 8 zwecks einer formschlüssigen Verbindung aufgenommen ist. Zudem ist in dem Hohlprofil 7 auch eine sich über die gesamte Länge des Brandschutztors 1 erstreckende Gewindestange 9 aufgenommen, welche in den äußeren Randbereichen des Brandschutztors 1 mit (nicht gezeigten) Aufnahmeteilen verspannt werden kann, so dass die Brandschutzelemente 2 in ihrem oberen sowie unteren Randbereich (vgl. Fig. 8) sowohl kraft- als auch formschlüssig miteinander verbunden sind.The fire protection elements 2 are in this case - as shown in particular in FIGS. 7 and 8 - in the upper and lower end region non-positively and positively connected to each other. For this purpose, each fire protection element 2 in an upper or lower end region has a substantially quadrangular hollow profile 7, in which a linear element or connecting part 8 extending over the entire length of the fire protection door 1 is received for the purpose of a positive connection. In addition, in the hollow section 7, a extending over the entire length of the fire door 1 threaded rod 9 is added, which can be clamped in the outer edge regions of the fire door 1 with (not shown) receiving parts, so that the fire protection elements 2 in its upper and lower edge region (see Fig. 8) both non-positively and positively with each other are connected.

Um insbesondere einen seitlichen Versatz, d.h. ein Verschieben der Brandschutzelemente quer zu ihrer Längserstreckungsrichtung zu vermeiden, sind zusätzlich zu den kraft- und formschlüssigen Verbindungen im oberen und unteren Endbereich der Brandschutzelemente abhängig von der Höhe der Brandschutzelemente bzw. etwaiger Einbauten (vgl. z.B. Türe 10 in Fig. 1) zusätzliche Verbindungen zwischen benachbarten Brandschutzelementen 2 vorgesehen.In particular, a lateral offset, i. to avoid a displacement of the fire protection elements transversely to their longitudinal direction, in addition to the non-positive and positive connections in the upper and lower end of the fire protection elements depending on the height of the fire protection elements or any installations (see, eg, door 10 in Fig. 1) additional connections provided between adjacent fire protection elements 2.

In Fig. 3 ist ersichtlich, dass an den im Wesentlichen planen stirnseitigen Flächen 3 der Brandschutzelemente 2 Verbindungselemente 11 vorgesehen sind, so dass zumindest ein seitlicher Versatz der Brandschutzelemente 2 im Bereich der zusammenwirkenden Verbindungselemente 11 benachbart der Brandschutzelemente 2 verhindert wird. Bei dem in Fig. 3 gezeigten Ausführungsbeispiel ist - wie insbesondere in Fig. 3a ersichtlich - jeweils ein im Wesentlichen sternförmiges Verbindungselement 11 vorgesehen, welches an den nach innen gebogenen Randbereichen 4' der Deckplatten 4 unter Zwischenlage des Brandschutzstreifens 6 über Nieten 12 befestigt ist. Die im Wesentlichen sternförmigen Verbindungselemente 11 weisen jeweils eine mittige Öffnung 13 zur Aufnahme eines Verbindungsteils 14 auf, so dass benachbarte Brandschutzelemente 2 durch das Hindurchführen durch die mittige Öffnung 13 eines Verbindungsteils 14 formschlüssig miteinander verbunden sind. Sofern wie in Fig. 3 ersichtlich als Verbindungsteil 14 eine Gewindestange 15 vorgesehen ist, können die Brandschutzelemente 2, durch welche die Gewindestange 15 hindurchgeführt wird, zusätzlich über endseitige, auf der Gewindestange befestigte Aufnahmeteile kraftschlüssig miteinander verspannt werden.In FIG. 3 it can be seen that connecting elements 11 are provided on the substantially planar end faces 3 of the fire protection elements 2, so that at least lateral displacement of the fire protection elements 2 adjacent the cooperating connecting elements 11 adjacent to the fire protection elements 2 is prevented. In the exemplary embodiment shown in FIG. 3, a substantially star-shaped connecting element 11 is provided - as can be seen in particular in FIG. 3 a - which is fastened to the inwardly curved edge regions 4 'of the cover plates 4 by interposing the fire protection strip 6 via rivets 12. The substantially star-shaped connecting elements 11 each have a central opening 13 for receiving a connecting part 14, so that adjacent fire protection elements 2 are positively connected to each other by the passage through the central opening 13 of a connecting part 14. If, as shown in Fig. 3 as a connecting part 14, a threaded rod 15 is provided, the fire protection elements 2, through which the threaded rod 15 is passed, in addition to the end side, mounted on the threaded rod receiving parts are positively clamped together.

Aus Fig. 4 ist ersichtlich, dass die Gewindestange 15 durch eine Ausnehmung in der Füllschicht 5 geführt ist, wobei die Position der Gewindestange 15 zwischen den beiden Deckplatten 4 durch die Aufnahme in der Öffnung 13 von Verbindungselementen 11 festgelegt ist.From Fig. 4 it is seen that the threaded rod 15 is guided through a recess in the filling layer 5, wherein the position of the threaded rod 15 is fixed between the two cover plates 4 by the inclusion in the opening 13 of connecting elements 11.

In Fig. 5 und 5a ist ersichtlich, dass als Verbindungsteil 14 anstelle einer sich über mehrere Befestigungselemente 2 erstreckenden Gewindestange 15 ebenso ein Bolzen 15' vorgesehen sein kann, welcher fest mit einem Verbindungselement 11 verbunden ist und in der Öffnung 13 eines benachbart angeordneten Verbindungselements 11 zwecks formschlüssiger Verbindung zwischen den beiden Verbindungsteilen 11 aufgenommen ist. Wie insbesondere in Fig. 5a ersichtlich, ist hierbei das Verbindungselement 11 ebenfalls sternförmig ausgebildet und über Nieten 12 mit den Randbereichen 4' der Deckplatten 4 verbunden.In Fig. 5 and 5a it can be seen that as the connecting part 14th instead of a threaded rod 15 extending over a plurality of fastening elements 2, a bolt 15 'can also be provided which is fixedly connected to a connecting element 11 and accommodated in the opening 13 of an adjacently arranged connecting element 11 for the purpose of positive connection between the two connecting parts 11. As can be seen in particular in Fig. 5a, in this case the connecting element 11 is also formed star-shaped and connected by rivets 12 with the edge regions 4 'of the cover plates 4.

In Fig. 6 ist noch ersichtlich, dass die Verbindungselemente 11 insbesondere benachbart einer Aussparung in einem Brandschutzelement 2 beispielsweise zur Aufnahme einer Türe 10 (vgl. Fig. 1) auch zur Aufnahme eines Hohlprofils 15'' als Verbindungsteil 14 vorgesehen sein können, so dass zusätzlich zu der kraftschlüssigen Verbindung über eine Gewindestange 9', welche in dem Hohlprofil 15'' aufgenommen ist, auch eine formschlüssige Verbindung über ein in dem Hohlprofil 15'' eingesetztes Linearelement 8' vorgesehen sein kann, ähnlich wie in den oberen oder unteren Randbereichen der Brandschutzelemente 2. Um einen Wärmedurchgang zwischen den beiden Deckplatten 4, 4' möglichst zu vermeiden, ist zwischen dem Hohlprofil 15'' und den beiden Deckplatten 4 jeweils eine Wärmedämmschicht 16, die beispielsweise aus Ridurit® oder dgl. bestehen kann, vorgesehen.6, it can also be seen that the connecting elements 11, in particular adjacent to a recess in a fire protection element 2, for example for receiving a door 10 (cf., FIG. 1) can also be provided for receiving a hollow profile 15 "as a connecting part 14, so that in addition to the frictional connection via a threaded rod 9 ', which is received in the hollow profile 15' ', a positive connection via a in the hollow section 15' 'inserted linear element 8' may be provided, similar to the upper or lower edge regions of Fire protection elements 2. In order to avoid a heat transfer between the two cover plates 4, 4 'as possible, is between the hollow section 15' 'and the two cover plates 4 each have a thermal barrier coating 16, which may consist of Ridurit® or the like., Provided.

Wesentlich ist jedoch lediglich, dass zwischen den im Wesentlichen eine plane Stirnseite aufweisenden Brandschutzelementen 2 lokal Verbindungselemente 11 vorgesehen sind, um einen seitlichen Versatz der Brandschutzelemente 2 zueinander zu vermeiden.However, it is only essential that local connection elements 11 are provided between the fire protection elements 2, which essentially have a planar end face, in order to avoid a lateral offset of the fire protection elements 2 from one another.
