Definitions
- the present invention relates to connection profiles for connecting drywall to floors, floors and solid walls.
- the invention further relates to measures for the realization of fire protection in the field of connection profiles for drywall.
- Connection profiles for drywall are used to connect the drywall to a connection component, such as a wall. a floor slab, a floor and / or a solid wall used.
- a connection component such as a wall. a floor slab, a floor and / or a solid wall used.
- a connection profile generally has an approximately U-shaped cross-section, the base surface of which is mounted parallel to the attachment surface of the attachment component, so that its limb surfaces project from the relevant attachment surface.
- drywall panels such as e.g. Plasterboard, to be fixed.
- connection profile is attached to the connection component, wherein the drywall panels are attached to the legs of the connection profile at a defined distance from the connection component.
- sealing of the drywall in the region of a gap between the drywall and the Connection component for example by either a suitable sealant is introduced or filled the gap with mineral wool and provided on the surface with a sealing layer.
- a suitable sealant is introduced or filled the gap with mineral wool and provided on the surface with a sealing layer.
- the material in the joint between the drywall and the connection component hinders the movement of the drywall board relatively strongly. In order to achieve sufficient movement absorption, therefore, a relatively large joint width must be selected, which can be sealed only with increased effort.
- the sealing of the joint with a sealant is an additional step, which can be done only after the assembly of the drywall and also requires a two-sided access to the finished drywall.
- this approach is prone to error as the user must manually dose the amount of sealing material to adequately seal the joint.
- the width of the joint must be selected according to the material and properties of the sealant used. In particular, it must be ensured with an expansion of the joint that the sealant adheres sufficiently strong to the ground and can absorb the resulting tensile forces. Otherwise, there is a risk of detachment of the sealant from the connection component or cracking. In the case of a reduction in the joint width, the sealing compound can only be compressed to a limited extent due to its material properties, and there is a risk that it will be pushed out when the joint is dimensioned incorrectly.
- connection profile for a drywall known, in which a seal of the joints between drywall and terminal component is done by an intumescent strip.
- connection profile for a drywall is shown, with an intumescent between a wall and the connection profile Material is introduced, which expands in case of fire and so gets into the joint between the wall and the dry element and seals them. Furthermore, it is provided intumescent material to be arranged in the interior of the U-shaped cross section at a portion of the legs, which adjoins directly to an inner edge between the leg and a base part of the U-shaped connection profile.
- connection profile which avoids the above disadvantages and in particular ensures an improved assembly of a drywall. In this case a good tightness and a high movement absorption between the connection component and the drywall is to be achieved.
- connection profile for attaching a drywall to a terminal component according to claim 1 and by a drywall with a connection profile according to the independent claim.
- connection component such as a floor, a ceiling or a solid wall
- a connection component such as a floor, a ceiling or a solid wall
- connection profile an arrangement of an insulation element is provided in the interior of a U-shaped profile piece.
- the proposed connection profile can thus prevent a direct flame and thus a temperature entry on the leg surface of the profile piece, which faces away from the fire.
- the insulation element is designed such that it bears at least partially against the base surface of the profile piece and thus completely closes the profile piece in the region of a joint which forms between the drywall plate and the connection component. As a result, an entry of fire heat can be avoided on a cold-side portion of the connection profile. In addition, can be dispensed with by the provision of a fire-resistant insulation element on the use of additional high-priced, intumescent material.
- the insulating element may extend over the entire width of the base portion between opposing leg portions in the extension direction.
- an insulation element extends in corner sections at an edge between the inner surface of the base section and a respective inner surface of opposite leg sections of the U-shaped cross section in the extension direction.
- an inwardly directed further projection also referred to as holding element, in particular in the form of a bead or claw, or by embossing, may be provided on the inner surface of the base section, for example every 10 cm, in order to form-fit the insulation elements in the corner sections hold.
- the inner surfaces of the leg sections may be provided with a projection, in particular in the form of a bead, claw, web or step, in order to hold the insulation element in a form-fitting manner on the inner surface of the base section.
- These materials have particularly good fire retardant properties, and are preferably mineral materials and / or cooling materials.
- the insulation element may contain an ablative fire protection additive, it being possible to use both individual compounds and a mixture of several compounds as additives.
- ablative fire protection additives such materials that form energy-depleting layers by dehydration, which is embedded as in the form of water of crystallization, and water evaporation.
- the heat energy that has to be used to split off the water is thereby removed from the fire.
- those materials are used which chemically change or decompose, heat, sublime or melt on exposure to heat in an endothermic reaction. This cools the coated substrates. Often decomposition releases inert, ie non-flammable gases, such as carbon dioxide, which additionally dilute the oxygen in the immediate vicinity of the coated substrate.
- Suitable gas-releasing components are hydroxides, such as aluminum hydroxide and magnesium hydroxide and their hydrates, which split off water, and carbonates, such as calcium carbonate, which split off carbon dioxide.
- Basic carbonates can split off both water and CO 2 . Preference is given to a combination of components starting at different temperatures with the gas release. Thus, the elimination of water in aluminum hydroxide begins already at about 200 °, whereas the elimination of magnesium hydroxide starts at about 350 °, so that the gas is split off over a wider temperature range.
- Suitable ablative materials when exposed to heat are water-releasing inorganic hydroxides or hydrates, such as those of sodium, potassium, lithium, barium, calcium, magnesium, boron, aluminum, zinc, nickel, furthermore boric acid and their partially dehydrated derivatives.
- Example, the following compounds may be mentioned: LiNO 3 .3H 2 O, Na2CO3H20 (thermonatrite), Na 2 CO 3 ⁇ 7H 2 O, Na 2 CO 3 .10H 2 O (sodium carbonate), Na 2 Ca (CO 3) 2 ⁇ 2H 2 O (pirssonite), Na 2 Ca (CO 3 ) 2 .5H 2 O (Gaylussite), Na (HCO 3 ) Na 2 CO 3 .2H 2 O (Trona), Na 2 S 2 O 3 .5H 2 O, Na 2 O 3 Si-5H 2 O, KF ⁇ 2H 2 O, CaBr 2 ⁇ 2H 2 O, CaBr 2 ⁇ 6H 2 O, CaSO 4 ⁇ 2H 2 O (gypsum), Ca (S0 4 ) ⁇ 1 ⁇ 2H 2 O Bassanite), Ba (OH) 2 .8H 2 O, Ni (NO 3 ) 2 .6H 2 O, Ni (NO 3 ) 2 .4H 2 O, Ni

Description
Die vorliegende Erfindung betrifft Anschlussprofile zum Anschließen von Trockenbauwänden an Geschossdecken, Fußböden und Massivwänden. Die Erfindung betrifft weiterhin Maßnahmen zur Realisierung eines Brandschutzes im Bereich der Anschlussprofile für Trockenbauwände.The present invention relates to connection profiles for connecting drywall to floors, floors and solid walls. The invention further relates to measures for the realization of fire protection in the field of connection profiles for drywall.
Anschlussprofile für Trockenbauwände werden zur Verbindung der Trockenbauwand mit einem Anschlussbauteil, wie z.B. einer Geschossdecke, einem Fußboden und/oder einer Massivwand verwendet. Ein solches Anschlussprofil weist in der Regel einen etwa U-förmigen Querschnitt auf, dessen Basisfläche parallel zur Befestigungsfläche des Anschlussbauteils angebracht wird, so dass deren Schenkelflächen von der betreffenden Anschlussfläche abstehen. An die Schenkelflächen des Anschlussprofils können Trockenbauplatten, wie z.B. Gipskartonplatten, befestigt werden.Connection profiles for drywall are used to connect the drywall to a connection component, such as a wall. a floor slab, a floor and / or a solid wall used. Such a connection profile generally has an approximately U-shaped cross-section, the base surface of which is mounted parallel to the attachment surface of the attachment component, so that its limb surfaces project from the relevant attachment surface. To the leg surfaces of the connection profile drywall panels, such as e.g. Plasterboard, to be fixed.
Im Allgemeinen wird das Anschlussprofil an das Anschlussbauteil angebracht, wobei die Trockenbauplatten mit einem definierten Abstand zum Anschlussbauteil an den Schenkeln des Anschlussprofils angebracht sind. Üblicherweise erfolgt die Abdichtung der Trockenbauwand im Bereich einer Fuge zwischen der Trockenbauplatte und dem Anschlussbauteil, z.B. indem entweder eine geeignete Dichtmasse eingebracht wird oder die Fuge mit Mineralwolle gefüllt und an der Oberfläche mit einer abdichtenden Schicht versehen wird. In beiden Fällen behindert das in der Fuge zwischen Trockenbauwand und Anschlussbauteil befindliche Material die Bewegung der Trockenbauplatte relativ stark. Zur Erzielung einer ausreichenden Bewegungsaufnahme muss daher eine verhältnismäßig große Fugenbreite gewählt werden, die sich nur mit erhöhtem Aufwand abdichten lässt.In general, the connection profile is attached to the connection component, wherein the drywall panels are attached to the legs of the connection profile at a defined distance from the connection component. Usually, the sealing of the drywall in the region of a gap between the drywall and the Connection component, for example by either a suitable sealant is introduced or filled the gap with mineral wool and provided on the surface with a sealing layer. In both cases, the material in the joint between the drywall and the connection component hinders the movement of the drywall board relatively strongly. In order to achieve sufficient movement absorption, therefore, a relatively large joint width must be selected, which can be sealed only with increased effort.
Weiterhin stellt die Abdichtung der Fuge mit einer Dichtmasse einen zusätzlichen Arbeitsschritt dar, der erst nach der Montage der Trockenbauplatten erfolgen kann und zudem einen beidseitigen Zugang zu der fertiggestellten Trockenbauwand erfordert. Darüber hinaus ist diese Vorgehensweise fehleranfällig, da der Anwender manuell die Menge an Dichtmaterial dosieren muss, um die Fuge ausreichend abzudichten.Furthermore, the sealing of the joint with a sealant is an additional step, which can be done only after the assembly of the drywall and also requires a two-sided access to the finished drywall. In addition, this approach is prone to error as the user must manually dose the amount of sealing material to adequately seal the joint.
Darüber hinaus muss aufgrund des begrenzten Dehn- und Komprimiervermögen der Dichtungsmasse von ca. maximal ± 25% die Breite der Fuge entsprechend dem Material und den Eigenschaften der verwendeten Dichtungsmasse gewählt werden. Insbesondere muss bei einer Ausdehnung der Fuge gewährleistet sein, dass die Dichtmasse ausreichend stark am Untergrund haftet und die entstehenden Zugkräfte aufnehmen kann. Andernfalls besteht eine Gefahr des Ablösens der Dichtungsmasse vom Anschlussbauteil oder der Rissbildung. Im Fall einer Verringerung der Fugenbreite kann die Dichtungsmasse aufgrund ihrer Materialeigenschaften nur begrenzt komprimiert werden, und es besteht die Gefahr, dass diese bei falsch dimensionierter Fuge herausgedrückt wird.In addition, due to the limited expansion and compression capability of the sealant of about a maximum of ± 25%, the width of the joint must be selected according to the material and properties of the sealant used. In particular, it must be ensured with an expansion of the joint that the sealant adheres sufficiently strong to the ground and can absorb the resulting tensile forces. Otherwise, there is a risk of detachment of the sealant from the connection component or cracking. In the case of a reduction in the joint width, the sealing compound can only be compressed to a limited extent due to its material properties, and there is a risk that it will be pushed out when the joint is dimensioned incorrectly.
Zum Abdichten der Fugen existieren einige weitere Lösungen, insbesondere Fugenschnüre oder Fugensprays, die ähnliche Nachteile haben.To seal the joints, there are some other solutions, in particular joint cords or joint sprays, which have similar disadvantages.

Es ist Aufgabe der vorliegenden Erfindung, ein Anschlussprofil bereitzustellen, das die obigen Nachteile vermeidet und insbesondere eine verbesserte Montage einer Trockenbauwand gewährleistet Dabei soll eine gute Dichtigkeit und eine hohe Bewegungsaufnahme zwischen dem Anschlussbauelement und der Trockenbauplatte erreicht werden.It is an object of the present invention to provide a connection profile which avoids the above disadvantages and in particular ensures an improved assembly of a drywall. In this case a good tightness and a high movement absorption between the connection component and the drywall is to be achieved.
Die obige Aufgabe wird durch ein Anschlussprofil zum Anbringen einer Trockenbauwand an ein Anschlussbauelement gemäß Anspruch 1 sowie durch eine Trockenbauwand mit einem Anschlussprofil gemäß dem nebengeordneten Anspruch gelöst.The above object is achieved by a connection profile for attaching a drywall to a terminal component according to claim 1 and by a drywall with a connection profile according to the independent claim.
Weitere Ausgestaltungen sind in den abhängigen Ansprüchen angegeben.Further embodiments are specified in the dependent claims.
Gemäß einem ersten Aspekt ist ein Anschlussprofil zum Anbringen einer Trockenbauwand an ein Anschlussbauelement, insbesondere einem Fußboden, einer Raumdecke oder einer Massivwand, vorgesehen, umfassend:
- ein sich in einer Erstreckungsrichtung erstreckendes Profilstück mit einem u-förmigen Querschnitt;
- mindestens ein Isolationselement, das an einer Innenfläche eines Basisabschnitts des u-förmigen Querschnitts angeordnet ist,
- an extending in a direction of extension profile piece with a U-shaped cross-section;
- at least one insulating member disposed on an inner surface of a base portion of the U-shaped cross section,
Üblicherweise wird zur Aufnahme von Bewegungen zwischen einer Trockenbauplatte und einem Anschlussbauelement, wie z.B. einem Fußboden, einer Raumdecke oder einer Massivwand, ein Abstand vorgesehen, durch den ein zur Befestigung der Trockenbauplatte verwendetes Anschlussprofil von außen zugänglich ist. Im Brandfall kann dadurch Hitze unmittelbar auf das Material des Anschlussprofils einwirken, und es kann kaltseitig auf der Profiloberfläche zu einer kritischen Temperaturerhöhung kommen.Usually, to accommodate movements between a drywall and a connection component, such as a floor, a ceiling or a solid wall, provided a distance through which a connection profile used for fastening the drywall is accessible from the outside. In the event of fire, heat can thus act directly on the material of the connection profile, and it can come on the cold side of the profile surface to a critical temperature increase.
Um dies zu vermeiden, ist gemäß dem vorgeschlagenen Anschlussprofil eine Anordnung eines Isolationselements im Inneren eines U-förmigen Profilstücks vorgesehen. Das vorgeschlagene Anschlussprofil kann so eine direkte Beflammung und damit einen Temperatureintrag auf die Schenkelfläche des Profilstücks, die dem Brand abgewandt ist, verhindern.To avoid this, according to the proposed connection profile, an arrangement of an insulation element is provided in the interior of a U-shaped profile piece. The proposed connection profile can thus prevent a direct flame and thus a temperature entry on the leg surface of the profile piece, which faces away from the fire.
Das Isolationselement ist dabei so ausgebildet, dass dieses zumindest teilweise an der Basisfläche des Profilstücks anliegt und damit das Profilstück im Bereich einer sich zwischen der Trockenbauplatte und dem Anschlussbauelement ausbildenden Fuge vollständig verschließt. Dadurch kann ein Eintrag von Brandhitze auf einen kaltseitigen Abschnitt des Anschlussprofils vermieden werden. Zudem kann durch das Vorsehen eines brandfesten Isolationselementes auf den Einsatz von zusätzlichem hochpreisigem, intumeszierendem Material verzichtet werden.The insulation element is designed such that it bears at least partially against the base surface of the profile piece and thus completely closes the profile piece in the region of a joint which forms between the drywall plate and the connection component. As a result, an entry of fire heat can be avoided on a cold-side portion of the connection profile. In addition, can be dispensed with by the provision of a fire-resistant insulation element on the use of additional high-priced, intumescent material.
Weiterhin kann sich das Isolationselement über die gesamte Breite des Basisabschnitts zwischen einander gegenüberliegenden Schenkelabschnitten in der Erstreckungsrichtung erstrecken.Furthermore, the insulating element may extend over the entire width of the base portion between opposing leg portions in the extension direction.
Es kann vorgesehen sein, dass sich jeweils ein Isolationselement in Eckabschnitten an einer Kante zwischen der Innenfläche des Basisabschnitts und einer jeweiligen Innenfläche voneinander gegenüberliegenden Schenkelabschnitten des u-förmigen Querschnitts in der Erstreckungsrichtung erstreckt.It can be provided that in each case an insulation element extends in corner sections at an edge between the inner surface of the base section and a respective inner surface of opposite leg sections of the U-shaped cross section in the extension direction.
Insbesondere kann für jeden Eckabschnitt ein nach innen gerichteter weiterer Vorsprung, auch als Halteelement bezeichnet, insbesondere in Form einer Sicke oder auch Kralle oder durch Eiprägungen, an der Innenfläche des Basisabschnitts vorgesehen sein, beispielsweise alle 10 cm, um die Isolationselemente formschlüssig in den Eckabschnitten zu halten.In particular, an inwardly directed further projection, also referred to as holding element, in particular in the form of a bead or claw, or by embossing, may be provided on the inner surface of the base section, for example every 10 cm, in order to form-fit the insulation elements in the corner sections hold.
Gemäß einer Ausführungsform können die Innenflächen der Schenkelabschnitte mit einem Vorsprung, insbesondere in Form einer Sicke, Kralle, Stegs oder Stufe, versehen sein, um das Isolationselement formschlüssig an der Innenfläche des Basisabschnitts zu halten.According to one embodiment, the inner surfaces of the leg sections may be provided with a projection, in particular in the form of a bead, claw, web or step, in order to hold the insulation element in a form-fitting manner on the inner surface of the base section.
Weiterhin kann das Isolationselement ein oder mehrere der folgenden Materialien aufweisen:
- ein mineralisches Material;
- ein Gipskartonmaterial;
- ein Gipsfasermaterial;
- ein Zementfasermaterial;
- einen Geopolymerschaum;
- ein temperaturbeständiges Polymer bzw. einen temperaturbeständigen Polymerschaum;
- ein Silikonmaterial; und
- Calcium-Silikat.
- a mineral material;
- a plasterboard material;
- a gypsum fiber material;
- a cement fiber material;
- a geopolymer foam;
- a temperature-resistant polymer or a temperature-resistant polymer foam;
- a silicone material; and
- Calcium silicate.
Diese Materialien weisen besonders gute brandhemmende Eigenschaften auf, und sind vorzugsweise mineralische Werkstoffe und/oder kühlende Werkstoffe.These materials have particularly good fire retardant properties, and are preferably mineral materials and / or cooling materials.
Weiterhin kann das Isolationselement ein ablativ wirkendes Brandschutzadditiv enthalten, wobei als Additive sowohl einzelne Verbindungen als auch ein Gemisch von mehreren Verbindungen verwendet werden kann.Furthermore, the insulation element may contain an ablative fire protection additive, it being possible to use both individual compounds and a mixture of several compounds as additives.
Zweckmäßig werden als ablativ wirkende Brandschutzadditive solche Materialien eingesetzt, die durch Wasserabspaltung, das etwa in Form von Kristallwasser eingelagert ist, und Wasserverdampfung energieverzehrende Schichten bilden. Die Wärmeenergie, die zur Abspaltung des Wassers aufgewendet werden muss, wird dabei dem Brand entzogen. Ferner werden solche Materialien eingesetzt, die sich bei Hitzeeinwirkung in einer endothermen Reaktion chemisch verändern bzw. zersetzen, verdampfen, sublimieren oder schmelzen. Dadurch werden die beschichteten Substrate gekühlt. Häufig werden bei der Zersetzung inerte, d.h. nicht brennbare Gase wie etwa Kohlendioxid freigesetzt, welche zusätzlich den Sauerstoff in unmittelbarer Umgebung des beschichteten Substrates verdünnen.Appropriately used as ablative fire protection additives such materials that form energy-depleting layers by dehydration, which is embedded as in the form of water of crystallization, and water evaporation. The heat energy that has to be used to split off the water is thereby removed from the fire. Furthermore, those materials are used which chemically change or decompose, heat, sublime or melt on exposure to heat in an endothermic reaction. This cools the coated substrates. Often decomposition releases inert, ie non-flammable gases, such as carbon dioxide, which additionally dilute the oxygen in the immediate vicinity of the coated substrate.
Als gasabspaltende Bestandteile eignen sich Hydroxide, wie Aluminiumhydroxid und Magnesiumhydroxid sowie deren Hydrate, die Wasser abspalten, sowie Carbonate, wie Calciumcarbonat, die Kohlendioxid abspalten. Basische Carbonate können sowohl Wasser als auch CO2 abspalten. Bevorzugt ist eine Kombination von bei verschiedenen Temperaturen mit der Gasabspaltung beginnenden Bestandteilen. So beginnt die Wasserabspaltung bei Aluminiumhydroxid bereits bei ca. 200°, wogegen die Wasserabspaltung von Magnesiumhydroxid bei ca. 350° einsetzt, so dass die Gasabspaltung über einen größeren Temperaturbereich hinweg erfolgt.Suitable gas-releasing components are hydroxides, such as aluminum hydroxide and magnesium hydroxide and their hydrates, which split off water, and carbonates, such as calcium carbonate, which split off carbon dioxide. Basic carbonates can split off both water and CO 2 . Preference is given to a combination of components starting at different temperatures with the gas release. Thus, the elimination of water in aluminum hydroxide begins already at about 200 °, whereas the elimination of magnesium hydroxide starts at about 350 °, so that the gas is split off over a wider temperature range.
Geeignete ablativ wirkende Materialien sind, bei Hitzeeinwirkung wasserabgebende anorganische Hydroxide oder Hydrate, wie solche von Natrium, Kalium, Lithium, Barium, Calcium, Magnesium, Bor, Aluminium, Zink, Nickel, ferner Borsäure und deren teilentwässerte Derivate.Suitable ablative materials, when exposed to heat are water-releasing inorganic hydroxides or hydrates, such as those of sodium, potassium, lithium, barium, calcium, magnesium, boron, aluminum, zinc, nickel, furthermore boric acid and their partially dehydrated derivatives.
Beispielhaft können folgende Verbindungen genannt werden: LiNO3·3H2O, Na2CO3H20 (Thermonatrit), Na2CO3·7H2O, Na2CO3·10H2O (Soda), Na2Ca(CO3)2·2H2O (Pirssonit), Na2Ca(CO3)2·5H2O (Gaylussit), Na(HCO3)Na2CO3·2H2O (Trona), Na2S2O3·5H2O, Na2O3Si-5H2O, KF·2H2O, CaBr2·2H2O, CaBr2·6H2O, CaSO4·2H2O (Gips), Ca(S04)·½H2O (Bassanit), Ba(OH)2·8H2O, Ni(NO3)2·6H2O, Ni(NO3)2·4H2O, Ni(NO3)2·2H2O, Zn(NO3)2·4H2O, Zn(NO3)2·6H2O, (ZnO)2(B2O3)2·3H2O, Mg(NO3)2·6H2O (
Das Isolationselement kann als ein Band aus intumeszierenden Material entlang der Innenfläche des Basisabschnitts oder als intumeszierende Beschichtung auf der Innenfläche des Basisabschnitts vorgesehen sein.The insulating member may be provided as a band of intumescent material along the inner surface of the base portion or as an intumescent coating on the inner surface of the base portion.
Insbesondere kann sich das Band aus intumeszierenden Material oder die intumeszierenden Beschichtung auch über einen Bereich der Innenflächen der Schenkelabschnitte erstrecken, der sich an eine Kante zwischen der Innenfläche des Basisabschnitts und der jeweiligen Innenfläche der Schenkelabschnitte anschließt.In particular, the band of intumescent material or the intumescent coating may also extend over a portion of the inner surfaces of the leg portions which adjoin an edge between the inner surface of the base portion and the respective inner surface of the leg portions.
Gemäß einem weiteren Aspekt ist eine Trockenbauwand mit dem obigen Anschlussprofil vorgesehen, wobei das Anschlussprofil an einem Anschlussbauelement angebracht ist, wobei an Außenflächen der Schenkelabschnitte des u-förmigen Querschnitts des Profilstücks Trockenbauplatten befestigt sind, so dass diese quer von dem Anschlussbauelement abstehen.According to a further aspect, a drywall is provided with the above connection profile, wherein the connection profile is attached to a terminal component, wherein drywall panels are attached to outer surfaces of the leg portions of the U-shaped cross section of the profile piece, so that they protrude transversely from the terminal component.
Es kann vorgesehen sein, dass zwischen dem Anschlussbauelement und einer Außenfläche des Basisabschnitts des Profilstücks ein oder mehrere Streifen eines Dichtelements, insbesondere aus intumeszierenden Material, entlang der Erstreckungsrichtung angeordnet sind.It can be provided that one or more strips of a sealing element, in particular of intumescent material, are arranged along the extension direction between the connection component and an outer surface of the base section of the profile piece.
Weiterhin können das Anschlussbauelement und die Trockenbauplatte mit einem Abstand angeordnet sein, so dass eine Fuge in Erstreckungsrichtung ausgebildet wird.Furthermore, the terminal component and the drywall can be arranged at a distance, so that a gap is formed in the extension direction.

Das Profilstück 3 weist einen im Wesentlichen U-förmigen Querschnitt auf und erstreckt sich schienenartig entlang der Erstreckungsrichtung (in die Zeichenebene) der Trockenbauwand 1 im Anschlussbereich A. Das Profilstück 3 ist üblicherweise aus einem metallischen Material (Blechmaterial) ausgebildet, insbesondere aus einem Metallblech durch ein oder mehrere Stanzvorgänge und einen anschließenden Biegeprozess hergestellt. Das U-förmige Profilstück 3 weist dadurch einen Basisabschnitt 31 und zwei von dem Basisabschnitt 31 quer abstehende Schenkelabschnitte 32 auf. Das Profilstück 3 wird in geeigneter Weise mit einer Außenfläche des Basisabschnitts 31 an dem Anschlussbauelement 2 befestigt.In the connection area A, the drywall 1 is provided with a connection profile which has a
Zwischen den Schenkelabschnitten 32 kann von der Innenfläche des Basisabschnitts 31 beabstandet ein Kernelement 4 angeordnet sein, das einem Trägerelement der Trockenbauwand entspricht und mit einem Dämm- und/oder Isolationsmaterial ausgebildet sein kann. Das Kernelement 4 kann mit Hilfe von Schrauben 5 an einer oder beiden Schenkelabschnitte 32 des Profilstücks 3 befestigt sein, so dass ein Randbereich des Kernelements 4 zwischen die Schenkelabschnitte 32 reicht.

Üblicherweise werden derartige Profilstücke 3 mit regelmäßigen Schlitzen versehen, die verteilt entlang der Erstreckungsrichtung des Profilstücks 3 angeordnet sind. Damit die Schraubenköpfe der Schrauben 5 nicht über die durch die Breite des Basisabschnitts 31 definierte maximale Breite hervorstehen, kann ein Abschnitt der Schenkelabschnitten 32, durch den die Schrauben 5 zur Befestigung des Kernelements 4 eingebracht werden, ins Innere des U-förmigen Querschnitts, d.h. zueinander, versetzt sein, so dass sich eine Stufe 33 in den Schenkelabschnitten 32 ergibt.Usually
Um im Brandfall einen Durchtritt von Brandgasen zwischen dem Anschlussbauelement 2 und dem Basisabschnitt 31 des Profilstücks 3 zu verhindern, ist zwischen dem Anschlussbauelement 2 und dem Basisabschnitt 31 ein Dichtelement 8 aus einem schwer brennbaren Material bzw. einem intumeszierenden Material entlang der Erstreckung des Profilstücks 3 vorgesehen. In der dargestellten Ausführungsform kann das Dichtelement 8 streifenförmig an einem sich an eine Kante zwischen dem Basisabschnitt 31 und einem der Schenkelabschnitte 32 anschließenden Flächenabschnitt des Basisabschnitts 31 anschließen und sich vorzugsweise über die gesamte Erstreckungslänge des Profilstücks 3 erstrecken.In order to prevent a passage of combustion gases between the
Insbesondere kann das Dichtelement 8 aus einem brandhemmenden, brandfesten, intumeszierenden Material oder dergleichen ausgebildet sein.

Durch das Metallmaterial des Profilstücks 3 kann es dadurch zu einer Erhöhung der Temperatur auf der dem Brand abgewandten Seite des Profilstücks 3 kommen. Insbesondere kann sich durch die Wärmeleitung durch das Material des Profilstücks 3 bzw. durchdringende Rauchgase die Temperatur auf der dem Brand abgewandten Seite so weit erhöhen, dass es zu einer kritischen Temperaturüberschreitung, wie z.B. einer Überschreitung einer Entflammtemperatur, kommen kann.Through the joint 7, in the event of fire, flue gases and flames can come into contact with the
