Description

Die vorliegende Erfindung betrifft eine Tragkonstruktion in Brandschutzausführung bei Fenster, Türen und Fassaden, insbesondere Pfosten-Riegel-Konstruktionen wie auch Elementfassadenkonstruktionen, mit mindestens einem Pfosten, an dem mindestens ein Riegel fixiert ist, einem Einschiebling und einer Brandschutzplatte, wobei der mindestens eine Pfosten über einen Träger an einer Decke eines Gebäudes gehalten ist und der Einschiebling in einer Hohlkammer des Pfostens eingefügt ist.The present invention relates to a support structure in a fire protection design for windows, doors and facades, in particular post-transom constructions as well as element facade constructions, with at least one post to which at least one transom is fixed, an insert and a fire protection panel, with the at least one post over a support is held on a ceiling of a building and the insert is inserted into a hollow chamber of the post.

Die DE 10 2016 006 683 offenbart ein Tragwerksystem als Pfosten-Riegel-Konstruktion, bei der Kühlmaterial in den Pfosten oder Riegeln angeordnet wird, um im Brandfall die Profile zu kühlen und somit die Standzeit zu erhöhen. Dieses Kühlmaterial kann über einen bestimmten Zeitraum Wasser abgeben und die Standzeit geringfügig erhöhen, allerdings kann nach dem Verdampfen des Wassers die Tragstruktur aus Pfosten und Riegeln, die meist aus Aluminium hergestellt ist, abschmelzen. Dies führt dazu, dass die Verkleidung sich von der Tragstruktur löst und herabfallen kann. Der Brand kann somit schneller in dem Gebäude durchdringen und zu hohen Schäden führen.The DE 10 2016 006 683 discloses a structural system as a post-transom construction, in which cooling material is arranged in the posts or transoms in order to cool the profiles in the event of a fire and thus increase the service life. This cooling material can release water over a certain period of time and slightly increase the service life, but after the water has evaporated, the support structure made of posts and bars, which is usually made of aluminum, can melt. This causes the cladding to become detached from the supporting structure and may fall down. The fire can therefore penetrate the building more quickly and cause significant damage.

Die Einfügung von Brandschutzelementen ist zudem auch aus der DE 100 03 953 A1 bekannt.The insertion of fire protection elements is also from the DE 100 03 953 A1 known.

FR 2 754 283 offenbart eine Tragkonstruktion mit Pfosten, an denen Brandschutzelemente über Schrauben fixiert sind. FR 2 754 283 discloses a supporting structure with posts to which fire protection elements are fixed using screws.

Es ist daher Aufgabe der vorliegenden Erfindung, eine Tragkonstruktion in Brandschutzausführung zu schaffen, die im Brandfall eine längere Fixierung von Brandschutzplatten gewährleistet.It is therefore the object of the present invention to create a support structure in a fire protection design which ensures that fire protection panels are fixed for a longer period of time in the event of a fire.

Diese Aufgabe wird mit einer Tragkonstruktion mit den Merkmalen des Anspruches 1 gelöst.This task is achieved with a supporting structure with the features of claim 1.

Erfindungsgemäß ist an einem Pfosten der Tragkonstruktion ein Einschiebling in eine Hohlkammer eingefügt, wobei eine Brandschutzplatte über eine Agraffenhalterung umfassende Befestigungsmittel an dem Einschiebling fixiert ist, die eine Öffnung in der Wand des Pfostens durchgreift. Dadurch kann eine mechanische Lastabtragung im Brandfall über den Einschiebling erfolgen, der aus einem anderen Material hergestellt ist als der Pfosten. Wenn der Pfosten im Brandfall weich wird und schmilzt, kann über den Einschiebling eine sichere Fixierung der Brandschutzplatte gewährleistet werden.According to the invention, an insert is inserted into a hollow chamber on a post of the supporting structure, with a fire protection panel being fixed to the insert via a fastening means comprising a bracket holder, which passes through an opening in the wall of the post. This means that in the event of a fire, mechanical load transfer can take place via the insert, which is made of a different material than the post. If the post in In the event of a fire becoming soft and melting, the insert can be used to ensure secure fixation of the fire protection panel.

Als Branschutzmaterialien für die Brandschutzplatte können Materialien eingesetzt werden, die nach der DIN 4102 / DIN EN 13501 in der aktuellen Fassung als nicht brennbar mit A1 oder A2 einklassifiziert sind.Materials that are classified as non-combustible with A1 or A2 according to DIN 4102 / DIN EN 13501 in the current version can be used as fire protection materials for the fire protection board.

Vorzugsweise ist der Einschiebling an dem Träger gehalten, der an einer Decke eines Gebäudes fixiert ist. Der Träger kann beispielsweise als Stahlkonsole ausgebildet sein, der sowohl den Pfosten als auch den Einschiebling hält. Der Einschiebling kann mindestens eine Öffnung aufweisen, beispielsweise ein Langloch, das sich parallel zur Längsrichtung des Einschieblings erstreckt, die von mindestens einem Befestigungsbolzen durchgriffen ist, der an dem Träger fixiert ist. Dadurch kann eine sichere Fixierung des Einschieblings an dem Träger gewährleistet werden, wobei über eine Bewegbarkeit in Längsrichtung des Einschieblings Wärmespannungen ausgeglichen werden können.The insert is preferably held on the support, which is fixed to a ceiling of a building. The carrier can, for example, be designed as a steel bracket that holds both the post and the insert. The insert can have at least one opening, for example an elongated hole, which extends parallel to the longitudinal direction of the insert, which is penetrated by at least one fastening bolt that is fixed to the carrier. As a result, a secure fixation of the insertion element on the carrier can be ensured, with thermal stresses being able to be compensated for by movability in the longitudinal direction of the insertion element.

In einer bevorzugten Ausgestaltung fixieren die Befestigungsmittel die Brandschutzplatte gleichzeitig an dem Pfosten und dem Einschiebling. Dadurch kann die Anzahl der Befestigungsmittel reduziert werden.In a preferred embodiment, the fastening means fix the fire protection panel to the post and the insert at the same time. This allows the number of fasteners to be reduced.

Die Befestigungsmittel können ferner eine Seitenwand des Pfostens durchgreifen und die Brandschutzplatte zwischen zwei Pfosten anordnen. Als Befestigungsmittel können Befestigungsbolzen, Schrauben, Haken und/oder eine Agraffenhalterung vorgesehen sein. Die Befestigungsmittel können dabei aus Stahl hergestellt sein, um auch im Brandfall eine sichere Fixierung der Brandschutzplatte zu gewährleisten.The fastening means can also pass through a side wall of the post and arrange the fire protection panel between two posts. Fastening bolts, screws, hooks and/or a clasp holder can be provided as fastening means. The fasteners can be made of steel in order to ensure that the fire protection panel is securely fixed even in the event of a fire.

In einer bevorzugten Ausgestaltung ist der Einschiebling so angeordnet, dass er über einen Pfosten in Längsrichtung hervorsteht und der hervorstehende Teil des Einschieblings in einen zweiten Pfosten eingeschoben ist. Dadurch können zwei Pfosten fluchtend angeordnet werden und über den Einschiebling fixiert sein.In a preferred embodiment, the insert is arranged so that it protrudes over a post in the longitudinal direction and the protruding part of the insert is inserted into a second post. This means that two posts can be arranged in alignment and fixed via the insert.

Der Einschiebling ist vorzugsweise als Stahlprofil gebildet, wahlweise als Vollprofil oder Hohlprofil. Dabei muss der Einschiebling nicht eine Hohlkammer des Pfostens vollständig ausfüllen, sondern kann auch nur einen Teil der Hohlkammer belegen. Ein weiterer Teil der Hohlkammer kann wahlweise leer bleiben oder mit Brandschutzmaterial gefüllt sein, insbesondere Kühlmaterial, bei dem Wasser gebunden ist, das im Brandfall verdampft. Ein solches Kühlmaterial, beispielsweise Gipsplatten, kann sowohl in dem Pfosten als auch an der Außenseite angebracht sein.The insert is preferably formed as a steel profile, either as a solid profile or hollow profile. The insert does not have to completely fill a hollow chamber of the post, but can also only occupy part of the hollow chamber. Another part of the hollow chamber can either remain empty or be filled with fire protection material, in particular cooling material bound to the water that evaporates in the event of a fire. Such a cooling material, for example plasterboard, can be installed both in the post and on the outside.

Eine Tragkonstruktion 1 umfasst eine Vielzahl von vertikalen Pfosten 2, an denen einer oder mehrere Riegel 3 fixiert sind, wobei die Pfosten 2 und Riegel 3 als Pfosten-Riegel-Konstruktion ausgebildet sein können, aber auch zu einem Rahmen einer Elementfassade zusammengesetzt werden können. Die Tragkonstruktion 1 kann auch für Fenster, Türen und Fassaden eingesetzt werden.A supporting structure 1 comprises a plurality of vertical posts 2, to which one or more bars 3 are fixed, wherein the posts 2 and bars 3 can be designed as a post-bar construction, but can also be assembled into a frame of an element facade. The supporting structure 1 can also be used for windows, doors and facades.

Die Pfosten 2 und Riegel 3 bestehen vorzugsweise aus Leichtmetall, insbesondere Aluminium, und werden an einer Gebäudeöffnung fixiert. Hierfür ist an einer Decke 4 eines Gebäudes ein Träger 5 vorgesehen, der über Befestigungsbolzen 6 fest an der Decke 4 fixiert ist. Der Träger 5 ist dabei winkelförmig oder T-förmig ausgebildet und umfasst ein von der Decke 4 hervorstehendes Schwert, an dem ein Einschiebling 8 in Form eines Stahlprofils fixiert ist. Ferner kann an dem Träger 5 auch ein Pfosten 2 fixiert sein.The posts 2 and bars 3 are preferably made of light metal, in particular aluminum, and are fixed to a building opening. For this purpose, a support 5 is provided on a ceiling 4 of a building, which is firmly fixed to the ceiling 4 via fastening bolts 6. The carrier 5 is angular or T-shaped and includes a sword protruding from the ceiling 4, to which an insert 8 in the form of a steel profile is fixed. Furthermore, a post 2 can also be fixed to the carrier 5.

In Figur 1A ist in den Pfosten 2 ein Einschiebling 8 teilweise eingefügt, wobei der Einschiebling 8 als Stahlprofil ausgebildet ist und über Befestigungsbolzen 7 mit dem Träger 5 verbunden ist. Der Einschiebling 8 ist über Befestigungsmittel 9, beispielsweise Befestigungsbolzen, mit dem Pfosten 2 verbunden. Ferner sind an dem Einschiebling 8 schematisch dargestellte Befestigungsmittel 10 gezeigt, die eine dargestellte Brandschutzplatte mit dem Einschiebling 8 verbinden, wobei die Befestigungsmittel 10 sowohl den Pfosten 2 als auch die Brandschutzplatte an dem Einschiebling 8 fixieren.In Figure 1A an insert 8 is partially inserted into the post 2, the insert 8 being designed as a steel profile and being connected to the carrier 5 via fastening bolts 7. The insert 8 is connected to the post 2 via fastening means 9, for example fastening bolts. Furthermore, schematically illustrated fastening means 10 are shown on the insert 8, which connect an illustrated fire protection panel to the insert 8, wherein the fastening means 10 fix both the post 2 and the fire protection panel on the insert 8.

Wie aus Figur 1B ersichtlich ist, besitzt der Pfosten 2 auf der von der Decke 4 abgewandten Seite zwei Nuten 21 zum Einfügen von Dichtungsprofilen sowie eine mittige Schraubnut 22 zur Fixierung einer Andruckleiste.How out Figure 1B As can be seen, the post 2 has two grooves 21 on the side facing away from the ceiling 4 for inserting sealing profiles and a central screw groove 22 for fixing a pressure bar.

In den Figuren 2A bis 2C ist die Tragkonstruktion 1 im Bereich der Decke 4 in verschiedenen Schnittansichten gezeigt. An dem Schwert des Trägers 5 sind zwei Befestigungsbolzen 7 gezeigt, die Öffnungen 70 in Form von Langlöchern an dem Einschiebling 8 durchgreifen. Die Langlöcher erstrecken sich dabei parallel zur Längsrichtung des Einschieblings 8 und ermöglichen somit eine gewisse Bewegung des Einschieblings 8, um Wärmespannungen auszugleichen, aber sorgen dennoch für eine sichere Fixierung des Einschieblings 8 an dem Träger 5. Der Einschiebling 8 ist in eine Hohlkammer des Pfostens 2 eingeschoben und ist dort über Befestigungsmittel mit einer Brandschutzplatte verbunden, die einen inneren Teil 11 und einen äußeren Teil 12 umfasst. Der äußere Teil 12, also die äußere Brandschutzplatte, ist plattenförmig ausgebildet und kann beispielsweise Blech oder Glas umfassen und bildet die äußere sichtbare Oberfläche einer Fassade. Auf der Innenseite ist ein Teil 11 der Brandschutzplatte angeordnet, beispielsweise in Form einer Stahlkassette, die den inneren Abschluss der Brandschutzplatte bildet.In the Figures 2A to 2C the supporting structure 1 is shown in various sectional views in the area of the ceiling 4. On the sword of the carrier 5, two fastening bolts 7 are shown, which pass through openings 70 in the form of elongated holes on the insert 8. The elongated holes extend parallel to the longitudinal direction of the insert 8 and thus enable a certain movement of the insert 8 in order to compensate for thermal stresses, but still ensure a secure fixation of the insert 8 on the support 5. The insert 8 is in a hollow chamber of the post 2 inserted and is connected there via fasteners to a fire protection panel, which includes an inner part 11 and an outer part 12. The outer part 12, i.e. the outer fire protection panel, is plate-shaped and can, for example, comprise sheet metal or glass and forms the outer visible surface of a facade. A part 11 of the fire protection panel is arranged on the inside, for example in the form of a steel cassette, which forms the inner end of the fire protection panel.

Der äußere Teil 12 ist über einen Winkel 15 an dem Einschiebling 8 gehalten. Hierfür ist der Winkel 15 mit dem äußeren Teil 12 verbunden, und an dem nach innen ragenden Steg 13 ist eine Agraffenhalterung ausgebildet, also ein Steg, der auf einem Tragbolzen 14 aufliegt. Der Tragbolzen 14 ist an dem Einschiebling 8 fixiert. Dadurch kann im Brandfall, wenn der Pfosten 2 und der Riegel 3 weich werden oder schmelzen, eine Fixierung des äußeren Teils 12 der Brandschutzplatte über den Winkel 15 erfolgen, der auf dem Tragbolzen 14 abgestützt ist, und der Tragbolzen 14 kann die Gewichtskräfte über den Einschiebling 8 auf den Träger 5 einleiten. Dadurch wird ein Herabfallen des äußeren Teils 12 und somit auch des inneren Teils 11 der Brandschutzplatte verhindert.The outer part 12 is held on the insert 8 via an angle 15. For this purpose, the angle 15 is connected to the outer part 12, and a clasp holder is formed on the inwardly projecting web 13, i.e. a web that rests on a support bolt 14. The support bolt 14 is fixed to the insert 8. This means that in the event of a fire, when the post 2 and the bolt 3 become soft or melt, the outer part 12 of the fire protection panel can be fixed via the angle 15, which is supported on the support bolt 14, and the support bolt 14 can carry the weight forces via the insert 8 on the carrier 5 initiate. This prevents the outer part 12 and thus also the inner part 11 of the fire protection panel from falling.

Der äußere Teil 12 der Brandschutzplatte ist in der dargestellten Einbausituation an den Pfosten 2 und Riegeln 3 gehalten, wobei an der Außenseite Abdeckund Andruckleisten 16 vorgesehen sind, die den plattenförmigen äußeren Teil 12 gegen Dichtungen an den Pfosten 2 und Riegeln 3 drücken. Sollte die mechanische Fixierung über die Abdeck- und Andruckleisten 16 im Brandfall versagen, so kann der äußere Teil 12 dennoch nicht herabfallen und die Gebäudeöffnung freigeben, da über die Befestigungsmittel mit der Agraffenhalterung mit dem Steg 13, dem Tragbolzen 14 und dem Einschiebling 8 eine Fixierung an dem Träger 5 gewährleistet wird, der an der Decke 4 angeordnet ist. Die Befestigungsmittel und der Träger 5 sind vorzugsweise aus Stahl hergestellt, der erst bei mehr als 1.500 °C schmilzt. Die Profile des Pfostens 2 und der Riegel 3 können aus einem anderen Material, beispielsweise aus Aluminium, dargestellt sein.In the installation situation shown, the outer part 12 of the fire protection panel is held on the posts 2 and bars 3, with cover and pressure strips 16 being provided on the outside, which press the plate-shaped outer part 12 against seals on the posts 2 and bars 3. Should the mechanical If fixation via the cover and pressure strips 16 fails in the event of a fire, the outer part 12 cannot fall down and release the building opening, since the fastening means with the clasp holder with the web 13, the support bolt 14 and the insert 8 provide fixation to the carrier 5 is ensured, which is arranged on the ceiling 4. The fastening means and the carrier 5 are preferably made of steel, which only melts at more than 1,500 ° C. The profiles of the post 2 and the bars 3 can be made of a different material, for example aluminum.

Der innere Teil 11 der Brandschutzplatte kann als Stahlkassette ausgebildet sein, beispielsweise gefüllt mit Isoliermaterial.The inner part 11 of the fire protection panel can be designed as a steel cassette, for example filled with insulating material.

In den Figuren 3A und 3B sind zwei Pfosten 2 gezeigt, die über den Einschiebling 8 miteinander verbunden werden. Der Einschiebling 8 steht über den unteren Pfosten 2 hervor und kann daher in eine Hohlkammer des oberen Pfostens 2 eingefügt werden, so dass die beiden Pfosten 2 in der montierten Position fluchtend angeordnet sind. In jedem Pfosten 2 sind Formkörper aus kühlendem Brandschutzmaterial 20 eingefügt, insbesondere ein Material, das Wasser in physikalischer und/oder chemischer Form bindet, beispielsweise in Form von Kristallwasser, damit dieses dann im Brandfall kühlen und verdampfen kann. Das Brandschutzmaterial 20 ist in dem Bereich benachbart zu dem Einschiebling 8 in Längsrichtung in den Pfosten 2 eingefügt.In the Figures 3A and 3B Two posts 2 are shown, which are connected to one another via the insert 8. The insert 8 protrudes above the lower post 2 and can therefore be inserted into a hollow chamber of the upper post 2 so that the two posts 2 are arranged in alignment in the assembled position. In each post 2, shaped bodies made of cooling fire protection material 20 are inserted, in particular a material that binds water in physical and/or chemical form, for example in the form of crystal water, so that it can then cool and evaporate in the event of a fire. The fire protection material 20 is inserted in the longitudinal direction into the post 2 in the area adjacent to the insert 8.

In den Figuren 4A und 4B ist der Einschiebling 8 gezeigt, der zwei nicht gezeigte Pfosten 2 miteinander verbindet. Auch um den Einschiebling 8 können Formkörper 30 aus Brandschutzmaterial vorgesehen werden, um auch den Bereich um den Einschiebling 8 im Brandfall zu kühlen.In the Figures 4A and 4B the insert 8 is shown, which connects two posts 2, not shown, to one another. Shaped bodies 30 made of fire protection material can also be provided around the insert 8 in order to also cool the area around the insert 8 in the event of a fire.

In dem dargestellten Ausführungsbeispiel sind diverse Befestigungsmittel gezeigt, um eine Brandschutzplatte über die Einschieblinge 8 an dem Träger 5 zu fixieren. Die Art der Befestigungsmittel kann vom Fachmann frei gewählt werden, und es müssen nicht die dargestellten Befestigungsmittel eingesetzt werden. Als Befestigungsmittel können Befestigungsbolzen, Haken, Winkel, Schrauben und andere Befestigungselemente eingesetzt werden, die vorzugsweise aus Stahl hergestellt sind und somit im Brandfall lange Zeit eine sichere Fixierung der Brandschutzplatten gewährleisten.In the exemplary embodiment shown, various fastening means are shown in order to fix a fire protection panel to the carrier 5 via the inserts 8. The type of fastening means can be freely chosen by the person skilled in the art and the fastening means shown do not have to be used. Fastening bolts, hooks, brackets, screws and other fastening elements can be used as fasteners, which are preferably made of steel and thus ensure that the fire protection panels are securely fixed for a long time in the event of a fire.
