Definitions
- the present invention relates to a fire bolt element and a fire bar, comprising at least two, in particular a plurality of fire bolt elements according to the invention, and the use of the inventive fire bolt element or the inventive fire bar as a fire barrier in thermal insulation systems for building facades and to connect or obstruct a cross-floor fire propagation in the insulation layer of thermal insulation systems. Furthermore, the invention relates to thermal insulation composite systems comprising at least one inventive fire lock element or a fire bar and building facades comprising at least one inventive fire lock element or at least one inventive fire bars or at least one inventive thermal insulation system.
- Thermal insulation systems for example based on foamed styrene polymers, when installed on building facades, in the event of a fire do not generally increase the risk of increased fire propagation in comparison with non-insulated building façades. This is partly due to the fact that thermal insulation systems are usually provided immediately after installation on the building facade with a mineral plaster layer, this not least also to avoid when using graphite or soot-containing Styrolpolymerisatdämmsysteme bowl formation by sunlight.
- EPS rigid foams are regularly used in construction for thermal insulation. These start at a temperature of over 100 ° C slowly soften and shrink. Only with further warming does the melting process begin. From the melt gaseous, combustible decomposition products can develop with prolonged heat. These can form flammable gases under fire conditions at temperatures above 350 ° C. Without a source of ignition, these thermal decomposition products ignite only at temperatures in the range of 450 ° C to 500 ° C. Up to these temperatures, EPS foam is not self-igniting, and it does not cause smoldering fire. As soon as the contact with a foreign flame, a so-called primary fire, is interrupted, generally neither further burning nor afterburning nor afterglow is observed.
- EPS rigid foam in Germany is a product that has been classified by the DIBt as having low flammability (B1 according to DIN 4102). It has also been shown that fire and carbonization gases, which emanate from EPS rigid foams, are less dangerous than the thermal decomposition products of cellulosic building materials such as wood fiber boards or cork.
- Structural fire protection measures are required in particular for external thermal insulation systems with insulation thicknesses greater than 100 mm in order to prevent the facade system from contributing to fire propagation through the façade.
- stone wool strips are used over lintels or so-called fire bars.
- Such fire bars may e.g. be formed of mineral wool or polyurethane.
- a fire bar is typically a substantially complete horizontal break in foam insulation, preferably at least every other storey made of a material that inhibits or prevents the spread of fire.
- Conventional fire bars are cuboidal products that are matched in their external dimensions to the thermal insulation composite system in which they are to be integrated. Accordingly, the foamed insulation material rests on the upper side of the rectangular fire bar, so that it does not come to form a thermal bridge.
- a fire protection element with a provided with Intumeszenzmasse protection means carrier, in which a transversely to a longitudinal extent strength conferring foam part is received in a formed by a fabric or by a nonwoven wrapping. At least part of this sheath or the foam part are used here as a protective agent carrier.
- This fire protection element is to obtain a more advantageous continuous fire bars.
- a special arrangement of the bonded pieces of fabric is needed to ensure a perfect connection with the facade.
- the AT 506 103 B1 deals with a fire barrier made of fire-resistant or fire-resistant material based on expanded polystyrene particles.
- the polystyrene granulate particles or beads are to be coated at least over partial areas of their surface with at least one fire or fire propagation inhibiting or refractory silicate.
- a Brandriegel made of it should be easy to install while ensuring adequate thermal insulation.
- U1 is a cuboid fire barrier consisting of a PUR or PIR hard foam out, which has a homogeneous cell structure over its entire thickness and at the same time has to be free of cover layers, for example of glass / mineral nonwoven, adhesive layers or fasteners.
- cover layers for example of glass / mineral nonwoven, adhesive layers or fasteners.
- optimal edge dynamic stiffness are present.
- Such a fire barrier should be particularly easy to manufacture and deliver in exactly the same thickness as the intended for each construction projects Polystyroldämmstoffplatten.
- the DE 10 2009 040 203 A1 describes a molded foam element of polyurethane foam or Polyisocyanuratschaum for thermal insulation composite systems on buildings with a cell structure having in at least two mutually perpendicular spatial directions distinguishable geometry structures.
- the EP 2 604 763 A1 is concerned with a fire bar, which is connected to a spacer which extends with a rear gap gap bridging portion between an outside of the fire bar and the inside of the facade cladding.
- This fire bar has to be made of an elastically deformable material. In this way, a building facade should be obtained with a simple, easy to assemble construction.
- the DE 10 2012 001 613 A1 relates to a thermal insulation composite system in which the fire barrier is formed from plate-shaped or profile-shaped thermal insulation elements which have airgel particles and at least one water-based inorganic and / or organic binder and have a thermal conductivity of less than or equal to 0.028 W / (mk).
- the fire barrier should be flexible and can be integrated, for example, in a lintel or soffit area of an opening in a building exterior wall.
- the DE 20 2012 100 418 U1 discloses a one-piece fire bar of fiber material which extends over the surface of an insulating layer in the direction of the facade cladding and which has a at least predominantly between the building wall and facade cladding aligned compressibility and / or flexibility.
- This fire bar is to allow a simple and inexpensive equipment of building facades with thermal insulation elements without additional structural elements are provided.
- the known from the prior art fire bars can still always wishes.
- the present invention therefore an object of the disadvantages associated with the use of generic fire bars, turn off or minimize and in particular to make available such fire bars with which a fire forwarding can be even more effectively obstructed or obstructed.
- a fire bolt element with a facade side attachable surface (also called facade side), one of the facade side opposite side (also called front surface), a bottom and a bottom opposite top surface, the top at least one support edge then the or adjacent to the front surface and then to or adjacent to the support edge at least one, in particular trough-shaped depression or an omission, each comprising a collecting tray comprises.
- the façade side of the fire bolt element according to the invention is to be understood as that side or surface of the fire bolt element which faces the façade mounted on a building facade and via which the connection to the façade generally takes place, for example by means of adhesive bonding.
- a façade or building façade is to be understood in this context as meaning a building façade side or wall or wall not provided with an insulating material.
- the front surface of the fire bolt element faces the visible side and is generally provided with a coating, for example a plaster layer, together with the thermal insulation composite system into which the fire bolt element is integrated.
- the underside of the fire-locking element according to the invention is to be understood as the surface or side facing the bottom surface in the case of conventional horizontal attachment of the fire-locking element. Accordingly, the side or surface of this fire-locking element should be understood as the upper side of the fire-locking element according to the invention, which points away from the floor surface or in the direction of the building roof or building top side when the fire-locking element is attached in the form of a horizontal fire bolt to a building facade.
- the distance between the facade side and the front surface, the thickness of the fire bolt element and the distance between the support edge of the top and bottom reflect the height of the fire bolt element.
- the length of the fire bolt element according to the invention ie the distance of the opposite side walls thereof, between which the top and bottom and the facade and the front side extend may be greater than, equal to or less than the height or thickness of the fire bolt element. It turned out to be expedient to resort to such inventive fire lock elements in which the length of the fire lock element is greater, in particular by a multiple greater than the height or in particular the thickness thereof. Usually, the length of easily manageable fire bar elements in the range of 0.4 m to 1.2 m.
- fire bars according to the invention By juxtaposing the fire bolt elements according to the invention flush over their respective side surfaces, one obtains a fire bar according to the invention, which is sometimes referred to as rotating fire bars.
- fire bars that extend along the length of a building, not designed in one piece, but formed from a variety of individual fire lock elements.
- individual fire bar elements can also be used to e.g. to be mounted only above a building opening or a fall. In such cases, for the sake of simplicity, one also regularly speaks of the presence of a bolt.
- the designation of the boundary surfaces of the inventive fire-barrier element with facade silk, front surface, underside and top side does not exclude that these surfaces or sides themselves may or may not be structured in themselves.
- the upper side of the fire bolt element according to the invention is characterized by a bearing edge, which adjoins the front surface or begins adjacent thereto and which is followed by a depression or an omission, each comprising a collecting tray.
- the support edge does not extend to this facade when attaching the fire bolt element to a facade, but at a distance from this facade ends, so that the facade side or surface of the fire bolt element according to the invention in the direction from the bottom to the top along a portion of the thickness extension of the fire lock element has a smaller extent than in the area of the front or - area.
- the collecting tray of the omission represents another part of the top of the fire bolt element according to the invention. Because this collecting tray is in conventional use, ie facing substantially horizontal orientation of the fire bolt element on a building facade of the building top. Accordingly, only by attaching the invention Brandriegelelements containing this omission to the building facade formed a trough or tub, which is open at the top, but no longer open to the façade side.
- a recess in particular a trough-shaped depression, adjoins the abovementioned support edge.
- this indentation is intended to differ from the described omission in that the facade side of the fire bolt element according to the invention has essentially the same or identical extent from the bottom to the top as the front surface or side from the bottom to the top ie to thennenlagerand.
- the recess may be bordered by the front bearing edge already described, also called the front bearing edge, and a facade side bearing edge extending from the facade side to the recess and may optionally, but not necessarily, also serve as a support for the underside of a thermal insulation board ,
- the recess as well as the omission may have different cross-sectional shapes.
- the cross-sectional shape of the recess in cross-section V-shaped, square, rectangular, trapezoidal (ie undercut), circular cut-out or otherwise configured as long as it allows a collecting tray to receive dripped molten Dämmstoffmaterialresten in case of fire and especially these residues not in the upper Adhere to the boundary wall and / or collect.
- the depression or omission of the inventive fire-barrier element preferably extends along the entire longitudinal alignment thereof.
- the support edge and the front surface adjoining thereto are arranged at least in sections essentially at right angles to one another.
- the front surface is usually after attachment of the fire bolt element on the building facade substantially parallel to this.
- a boundary wall extends regularly from the supporting edge to the collecting base of the depression or the omission.
- This boundary wall has in its upper portion, ie in the adjoining the support edge portion in the direction of the collecting tray preferably via a average extension of at least 2 cm, in particular at least 3 cm and more preferably at least 4 cm.
- In one embodiment of the invention may connect to this upper portion of the boundary wall substantially directly the collecting tray.
- the dimensioning of the boundary wall in the direction of the collecting tray to the support edge generally depends, inter alia, on the thickness of the foamed Dämm Anlagenmaterials into which the invention Brandriegel or the inventive fire lock element is integrated and thus of the amount of fire in the case of the omission or the Well to be absorbed molten foamed insulation residues.
- the depth of the depression or the omission, ie the extent of the support edge to the collecting tray is to be chosen regularly such that in the event of fire from the exposed to the insulating layer insulation molten or up and / or molten residues are collected to a not insignificant part without a secondary fire being created in or on the collecting tray.
- the trapped particles in the recess or the omission will not itself ignite a fire of possibly not yet burned insulation material above the firing bolt and can not be set on fire even by emerging from below from a building opening flames.
- the support edge is accordingly advantageously characterized by the fact that it is sufficiently wide as a bearing surface so that it can collect melted liquid or fused and / or fused residues of insulating material without immediately slipping into the recess or the recess and in particular also insulating material, eg in plate form, can be placed flush, to allow easy and at the same time thermal bridge-free installation.
- the sole continuous beveling the top of the bolt from the front surface to the front side, for example, at an angle of 45 °, is not enough to get to a fire bar according to the invention or to a fire bar with which set the effects of the invention.
- the support edge and the adjoining boundary wall are arranged substantially at right angles to one another, at least in the upper section adjoining this support edge.
- This upper portion may also be undercut, but may also be slightly inclined in the direction of the facade side, as long as it can be ensured that remain adhering to this upper area substantially no dripping molten or melted or fused Dämmmaterialreste.
- the upper region of the boundary wall preferably over an extension of at least 2 cm, in particular of at least 3 cm and more preferably of at least 4 cm, a slope in the direction of the facade side with respect to the vertical when attached to a building facade of a maximum of 10 °, preferably a maximum of 5 °.
- Fire bar elements according to the invention preferably contain or consist of mineral wool, in particular in the form of mineral wool lamella strips or mineral wool strip strips, thermoset foam, in particular rigid polyurethane foam (PUR foam) and / or rigid polyisocyanurate foam (PIR foam) and / or phenolic rigid foam (PF foam), mineral foam, in particular from wasserglas- and / or phosphate-bonded, and / or autoclave hardened and / or hydraulically curing and / or hydratically curing mineral foam, composites of silicates and foamed styrene polymers, composites of aerosol particles and a water-based organic and / or inorganic binder, glass cloth and / or needle felt.
- thermoset foam in particular rigid polyurethane foam (PUR foam) and / or rigid polyisocyanurate foam (PIR foam) and / or phenolic rigid foam (PF foam)
- mineral foam in particular from wasserglas- and / or phosphate-bonded, and / or
- the inventive fire-barrier element has an average height (measured from the underside to the support edge) of at least 8 cm, preferably at least 15 cm and particularly preferably at least 18 cm and / or an average thickness (measured from the facade side to the front surface) of at least 5 cm, preferably at least 8 cm and more preferably at least 10 cm.
- boundary wall and the collecting tray adjoining thereto form essentially a right angle.
- the transition from boundary wall to collecting base is chamfered or rounded.
- the material present in relation to a vertical boundary wall, in particular in the transition from the boundary wall to the collecting base has a stabilizing effect on the overall structure and allows more degrees of freedom in the dimensioning without having to make concessions with regard to the further effects according to the invention.
- At least the upper portion of the boundary wall is aligned in such a way that it runs when attaching the fire bolt element to a building facade substantially parallel to this or away from this, starting with the support edge, or that at least the upper portion the boundary wall is aligned in such a way that it runs substantially parallel to the extension of the facade side or away from this extension, starting with the support edge.
- inventive fire lock elements are preferred in which the extent of the boundary wall, in particular the extent of the upper region of the boundary wall, to the front surface is less than or equal to the extension of the collecting tray from the facade side in the direction of the front surface.
- Such Brandriegelieri invention in which the maximum extent of the depression or omission of the support edge to the collecting tray at least 1/5, preferably at least 2/5 and more preferably not more than 3/5 of the height of the fire bolt element or the fire bar includes.
- the depression or the extention is at least partially, in particular substantially completely, filled with at least one heat-shrinkable material, in particular foamed styrene polymer, which preferably has a maximum heat conduction of 0.060 W / mK , Even if the depression or omission, unlike the fire barrier element itself, is filled with a heat-shrinkable material and the overall component thereby forms a square or rectangular cross-sectional area, there is still an omission or depression within the meaning of the invention. Because as soon as the fire occurs, the omission or depression is released and can thus fulfill their effect according to the invention.

- inventive fire bolt elements or the fire bolt according to the invention can be used to building openings such as windows or doors selectively detect.
- the inventive fire lock element or the inventive fire bars can consequently, in particular when mounted in a horizontal orientation, be arranged in the area above falls, in particular door and / or window lintels, or above building openings, in particular door and / or window openings.
- the inventive fire bars a, in particular substantially continuous, interruption of a facade insulation comprising or consisting of foamed styrene polymers realized.
- the object underlying the invention is achieved by a composite thermal insulation system comprising or consisting of foamed styrene polymers for a building facade, comprising at least one inventive fire lock element or at least one inventive fire bars.
- the object underlying the invention is achieved by a building facade comprising at least one inventive Brandriegelelement or a fire bar according to the invention or an inventive thermal insulation composite system.
- the front surface of the fire bolt element or of the fire bolt can be substantially flush with the front side of the external thermal insulation composite system or the building facade or integrated flush therein.

- the novel fire bar elements or with the fire bar according to the invention has the surprising advantage that, in the case of a fire of, in particular, unpainted facades with a thermal insulation composite system containing thermal insulation materials based on styrene polymers, a significantly lower proportion of the molten styrene polymer collected on the upper side of the inventive fire-retainer / fire bar can burn. As a result, the fire load is significantly reduced above the fire bolt element / fire bar.

As a result, previously inaccessible places in the facade are not ignited in retrospect.
- the wall or facade area adjacent to the omission is adequately shielded by the front area, so that this area of the facade or the wall remains relatively cool and for the release of heat energy can be used by dripping into the omission molten or fused and / or fused insulating material, eg Styrolpolymerisatresten, whereby the latter should they themselves burn, quickly extinguish or, if they do not burn themselves, prevent spontaneous combustion.
- molten or fused and / or fused insulating material eg Styrolpolymerisatresten

- the controlled secondary firing of the molten styrene polymer residues on the support edge causes oxygen to be removed from molten residues in the recess.
- the air flow caused by this controlled secondary firing on the support edge in that part of the firestop facing the façade, in particular in the depression or extinction leads to a cooling of the molten insulating materials intercepted there, e.g. a styrene polymer.

Description
Die vorliegende Erfindung betrifft ein Brandriegelelement und einen Brandriegel, umfassend mindestens zwei, insbesondere eine Vielzahl an erfindungsgemäßen Brandriegelelementen, sowie die Verwendung des erfindungsgemäßen Brandriegelelements oder des erfindungsgemäßen Brandriegels als Brandsperre in Wärmedämmverbundsystemen für Gebäudefassaden sowie zur Ver- oder Behinderung einer geschossübergreifenden Brandweiterleitung in der Dämmebene von Wärmedämmverbundsystemen. Des Weiteren betrifft die Erfindung Wärmedämmverbundsysteme umfassend mindestens ein erfindungsgemäßes Brandriegelelement oder einen erfindungsgemäßen Brandriegel sowie Gebäudefassaden umfassend mindestens ein erfindungsgemäßes Brandriegelelement oder mindestens einen erfindungsgemäßen Brandriegel oder mindestens ein erfindungsgemäßes Wärmedämmverbundsystem.The present invention relates to a fire bolt element and a fire bar, comprising at least two, in particular a plurality of fire bolt elements according to the invention, and the use of the inventive fire bolt element or the inventive fire bar as a fire barrier in thermal insulation systems for building facades and to connect or obstruct a cross-floor fire propagation in the insulation layer of thermal insulation systems. Furthermore, the invention relates to thermal insulation composite systems comprising at least one inventive fire lock element or a fire bar and building facades comprising at least one inventive fire lock element or at least one inventive fire bars or at least one inventive thermal insulation system.
Wärmedämmverbundsysteme, beispielsweise auf Basis geschäumter Styrolpolymerisate, erhöhen, wenn an Gebäudefassaden angebracht, im Brandfall im Vergleich mit nicht gedämmten Gebäudefassaden regelmäßig nicht die Gefahr einer verstärkten Brandausbreitung. Dieses liegt unter anderem auch darin begründet, dass Wärmedämmverbundsysteme nach der Anbringung an der Gebäudefassade zumeist unverzüglich mit einer mineralischen Putzschicht versehen werden, dieses nicht zuletzt auch deshalb, um bei Verwendung graphit- oder rußhaltiger Styrolpolymerisatdämmsysteme Schüsselbildung durch Sonneneinstrahlung zu vermeiden.Thermal insulation systems, for example based on foamed styrene polymers, when installed on building facades, in the event of a fire do not generally increase the risk of increased fire propagation in comparison with non-insulated building façades. This is partly due to the fact that thermal insulation systems are usually provided immediately after installation on the building facade with a mineral plaster layer, this not least also to avoid when using graphite or soot-containing Styrolpolymerisatdämmsysteme bowl formation by sunlight.
In Deutschland werden im Bauwesen zur Wärmedämmung regelmäßig flammgeschützte EPS-Hartschaumstoffe eingesetzt. Diese beginnen bei einer Temperatur von über 100°C langsam zu erweichen und zu schrumpfen. Erst bei weiterer Erwärmung setzt der Schmelzvorgang ein. Aus der Schmelze können sich bei längerer Wärmeeinwirkung gasförmige, brennbare Zersetzungsprodukte entwickeln. Diese können unter Brandbedingungen bei Temperaturen oberhalb 350°C entzündbare Gase bilden. Ohne Zündquelle entzünden sich diese thermischen Zersetzungsprodukte erst bei Temperaturen im Bereich von 450°C bis 500°C. Bis zu diesen Temperaturen ist EPS-Hartschaum nicht selbstentzündlich, auch kommt es nicht zum Glimmbrand. Sobald der Kontakt mit einer Fremdflamme, einem sogenannten Primärbrand, unterbrochen wird, ist daher im Allgemeinen weder ein Weiterbrennen bzw. ein Nachbrennen noch ein Nachglimmen zu beobachten. Bei EPS-Hartschaum handelt es sich in Deutschland demgemäß um ein Produkt, dass vom DIBt als schwerentflammbar eingestuft worden ist (B1 nach DIN 4102). Auch hat sich gezeigt, dass Brand- und Schwelgase, die von EPS-Hartschäumen ausgehen, weniger gefährlich sind als die thermischen Zersetzungsprodukte von zellulosischen Baustoffen wie Holzfaserplatten oder Kork.In Germany, flame-retardant EPS rigid foams are regularly used in construction for thermal insulation. These start at a temperature of over 100 ° C slowly soften and shrink. Only with further warming does the melting process begin. From the melt gaseous, combustible decomposition products can develop with prolonged heat. These can form flammable gases under fire conditions at temperatures above 350 ° C. Without a source of ignition, these thermal decomposition products ignite only at temperatures in the range of 450 ° C to 500 ° C. Up to these temperatures, EPS foam is not self-igniting, and it does not cause smoldering fire. As soon as the contact with a foreign flame, a so-called primary fire, is interrupted, generally neither further burning nor afterburning nor afterglow is observed. Accordingly, EPS rigid foam in Germany is a product that has been classified by the DIBt as having low flammability (B1 according to DIN 4102). It has also been shown that fire and carbonization gases, which emanate from EPS rigid foams, are less dangerous than the thermal decomposition products of cellulosic building materials such as wood fiber boards or cork.
Insbesondere bei Wärmedämmverbundsystemen mit Dämmstoffdicken größer 100 mm werden konstruktive brandschutztechnische Maßnahmen gefordert, um zu verhindern, dass das Fassadensystem zu einer Brandweiterleitung über die Fassade beiträgt. Hierbei kommen zum Beispiel Steinwollestreifen über Fensterstürzen oder so genannte Brandriegel zum Einsatz. Solche Brandriegel können z.B. aus Mineralwolle oder Polyurethan gebildet sein.Structural fire protection measures are required in particular for external thermal insulation systems with insulation thicknesses greater than 100 mm in order to prevent the facade system from contributing to fire propagation through the façade. Here, for example, stone wool strips are used over lintels or so-called fire bars. Such fire bars may e.g. be formed of mineral wool or polyurethane.
Bei einem Brandriegel handelt es sich in der Regel um eine im Wesentlichen vollständige horizontale Unterbrechung der Schaumstoffdämmung vorzugsweise in mindestens jedem zweiten Geschoss aus einem Material, das die Brandausbreitung be- bzw. verhindert. Herkömmliche Brandriegel sind quaderförmige Produkte, die in ihren äußeren Abmessungen auf das Wärmedämmverbundsystem, in das sie zu integrieren sind, abgestimmt sind. Demgemäß liegt auf der Oberseite des quaderförmigen Brandriegels das geschäumte Isolationsmaterial auf, so dass es nicht zur Ausbildung einer Wärmebrücke kommt.A fire bar is typically a substantially complete horizontal break in foam insulation, preferably at least every other storey made of a material that inhibits or prevents the spread of fire. Conventional fire bars are cuboidal products that are matched in their external dimensions to the thermal insulation composite system in which they are to be integrated. Accordingly, the foamed insulation material rests on the upper side of the rectangular fire bar, so that it does not come to form a thermal bridge.

Die aus dem Stand der Technik bekannten Brandriegel lassen noch stets Wünsche offen. Der vorliegenden Erfindung lag daher die Aufgabe zugrunde, die Nachteile, die mit der Verwendung gattungsgemäßer Brandriegel einhergehen, abzustellen bzw. zu minimieren und insbesondere solche Brandriegel verfügbar zu machen, mit denen eine Brandweiterleitung noch wirkungsvoller ver- bzw. behindert werden kann.The known from the prior art fire bars can still always wishes. The present invention therefore an object of the disadvantages associated with the use of generic fire bars, turn off or minimize and in particular to make available such fire bars with which a fire forwarding can be even more effectively obstructed or obstructed.
Die der Erfindung zugrunde liegende Aufgabe wird gelöst durch ein Brandriegelelement mit einer fassadenseitig anbringbaren Fläche (auch Fassadenseite genannt), einer der Fassadenseite gegenüberliegenden Seite (auch Frontfläche genannt), einer Unterseite und einer der Unterseite gegenüberliegenden Oberseite, wobei die Oberseite mindestens einen Auflagerand anschließend an die oder benachbart zur Frontfläche und anschließend an den oder benachbart zu dem Auflagerand mindestens eine, insbesondere wannenförmige, Vertiefung oder eine Auslassung, jeweils umfassend einen Auffangboden, umfasst.The object underlying the invention is achieved by a fire bolt element with a facade side attachable surface (also called facade side), one of the facade side opposite side (also called front surface), a bottom and a bottom opposite top surface, the top at least one support edge then the or adjacent to the front surface and then to or adjacent to the support edge at least one, in particular trough-shaped depression or an omission, each comprising a collecting tray comprises.
Unter der Fassadenseite des erfindungsgemäßen Brandriegelelements soll diejenige Seite bzw. Fläche des Brandriegelelements verstanden werden, die im an eine Gebäudefassade montierten Zustand der Fassade zugewandt ist und über die im Allgemeinen auch, beispielsweise mittels Verklebung, die Anbindung an die Fassade stattfindet. Mit Fassade bzw. Gebäudefassade soll in diesem Zusammenhang im Sinne der Erfindung eine nicht mit einem Dämmmaterial versehene Gebäudefassadenseite bzw. -mauer oder -wand verstanden werden. Die Frontfläche des Brandriegelelements ist hingegen der Sichtseite zugewandt und wird im Allgemeinen zusammen mit dem Wärmedämmverbundsystem, in das das Brandriegelelement integriert wird, mit einer Beschichtung, beispielsweise einer Putzschicht, versehen. Unter der Unterseite des erfindungsgemäßen Brandriegelelements soll im Sinne der Erfindung diejenige Fläche bzw. Seite verstanden werden, die bei herkömmlicher horizontaler Anbringung des Brandriegelelements der Bodenfläche zugewandt ist. Unter der Oberseite des erfindungsgemäßen Brandriegelelements soll dementsprechend diejenige Seite bzw. Fläche dieses Brandriegelelements verstanden werden, welche bei Anbringung des Brandriegelelements in Form eines horizontalen Brandriegels an einer Gebäudefassade von der Bodenfläche weg bzw. in Richtung des Gebäudedaches bzw. der Gebäudeoberseite weist. Im Sinne der vorliegenden Erfindung soll der Abstand zwischen der Fassadenseite und der Frontfläche die Dicke des Brandriegelelements und der Abstand zwischen dem Auflagerand der Oberseite und der Unterseite die Höhe des Brandriegelelements wiedergeben. Die Länge des erfindungsgemäßen Brandriegelelements, d.h. der Abstand der sich gegenüberliegenden Seitenwände desselben, zwischen denen sich die Ober-und die Unterseite und die Fassaden- und die Frontseite erstrecken, kann größer, gleich oder kleiner sein als die Höhe oder die Dicke des Brandriegelelements. Es hat sich als zweckmäßig erwiesen, auf solche erfindungsgemäßen Brandriegelelemente zurückzugreifen, bei denen die Länge dieses Brandriegelelements größer ist, insbesondere um ein Vielfaches größer ist, als die Höhe bzw. insbesondere die Dicke desselben. Üblicherweise liegt die Länge von gut handhabbaren Brandriegelelementen im Bereich von 0,4 m bis 1,2 m.The façade side of the fire bolt element according to the invention is to be understood as that side or surface of the fire bolt element which faces the façade mounted on a building facade and via which the connection to the façade generally takes place, for example by means of adhesive bonding. In the context of the invention, a façade or building façade is to be understood in this context as meaning a building façade side or wall or wall not provided with an insulating material. On the other hand, the front surface of the fire bolt element faces the visible side and is generally provided with a coating, for example a plaster layer, together with the thermal insulation composite system into which the fire bolt element is integrated. For the purposes of the invention, the underside of the fire-locking element according to the invention is to be understood as the surface or side facing the bottom surface in the case of conventional horizontal attachment of the fire-locking element. Accordingly, the side or surface of this fire-locking element should be understood as the upper side of the fire-locking element according to the invention, which points away from the floor surface or in the direction of the building roof or building top side when the fire-locking element is attached in the form of a horizontal fire bolt to a building facade. For the purposes of the present invention, the distance between the facade side and the front surface, the thickness of the fire bolt element and the distance between the support edge of the top and bottom reflect the height of the fire bolt element. The length of the fire bolt element according to the invention, ie the distance of the opposite side walls thereof, between which the top and bottom and the facade and the front side extend may be greater than, equal to or less than the height or thickness of the fire bolt element. It turned out to be expedient to resort to such inventive fire lock elements in which the length of the fire lock element is greater, in particular by a multiple greater than the height or in particular the thickness thereof. Usually, the length of easily manageable fire bar elements in the range of 0.4 m to 1.2 m.
Indem man die erfindungsgemäßen Brandriegelelemente bündig über ihre jeweiligen Seitenflächen aneinanderreiht, erhält man einen erfindungsgemäßen Brandriegel, der mitunter auch als umlaufender Brandriegel bezeichnet wird. In der Regel werden Brandriegel, die sich entlang der Länge eines Gebäudes erstrecken, nicht einstückig ausgeführt, sondern aus einer Vielzahl an einzelnen Brandriegelelementen gebildet. Selbstverständlich können solche einzelnen Brandriegelelemente auch verwendet werden, um z.B. ausschließlich oberhalb einer Gebäudeöffnung bzw. eines Sturzes angebracht zu werden. In solchen Fällen spricht man der Einfachheit halber regelmäßig auch von dem Vorliegen eines Brandriegels.By juxtaposing the fire bolt elements according to the invention flush over their respective side surfaces, one obtains a fire bar according to the invention, which is sometimes referred to as rotating fire bars. In general, fire bars that extend along the length of a building, not designed in one piece, but formed from a variety of individual fire lock elements. Of course, such individual fire bar elements can also be used to e.g. to be mounted only above a building opening or a fall. In such cases, for the sake of simplicity, one also regularly speaks of the presence of a bolt.
Die Bezeichnung der Begrenzungsflächen des erfindungsgemäßen Brandriegelelements mit Fassadenseide, Frontfläche, Unterseite und Oberseite schließt nicht aus, dass diese Flächen bzw. Seiten selber in sich strukturiert sein können bzw. sind. So zeichnet sich die Oberseite des erfindungsgemäßen Brandriegelelements durch einen Auflagerand aus, der sich an die Frontfläche anschließt oder benachbart zu dieser beginnt und der gefolgt wird von einer Vertiefung oder einer Auslassung, welche jeweils einen Auffangboden umfassen. Indem die erfindungsgemäßen Brandriegel über die beschriebene Materialauslassung verfügen, unterscheiden sie sich signifikant von den gattungsgemäßen quaderförmigen Brandriegeln, die entweder eine quadratische oder rechteckige Querschnittsfläche aufweisen. Unter einer Auslassung im Sinne der vorliegenden Erfindung soll verstanden werden, dass der Auflagerand sich bei Anbringung des Brandriegelelements an eine Fassade nicht bis zu dieser Fassade erstreckt, sondern beabstandet von dieser Fassade endet, so dass die Fassadenseite bzw. -fläche des erfindungsgemäßen Brandriegelelements in Richtung von der Unterseite zur Oberseite entlang eines Abschnitts der Dickenerstreckung des Brandriegelelements über eine geringere Erstreckung verfügt als im Bereich der Frontseite bzw. - fläche. Mithin stellt bei dieser Ausführungsform der Auffangboden der Auslassung einen weiteren Teil der Oberseite des erfindungsgemäßen Brandriegelelements dar. Denn auch dieser Auffangboden ist bei üblicher Verwendung, d.h. im Wesentlichen horizontaler Ausrichtung des Brandriegelelements an einer Gebäudefassade der Gebäudeoberseite zugewandt. Dementsprechend wird erst durch Anbringung des erfindungsgemäßen Brandriegelelements enthaltend diese Auslassung an die Gebäudefassade eine Mulde oder Wanne gebildet, die nach oben offen, nicht mehr jedoch auch zur Fassadenseite hin offen ist.The designation of the boundary surfaces of the inventive fire-barrier element with facade silk, front surface, underside and top side does not exclude that these surfaces or sides themselves may or may not be structured in themselves. Thus, the upper side of the fire bolt element according to the invention is characterized by a bearing edge, which adjoins the front surface or begins adjacent thereto and which is followed by a depression or an omission, each comprising a collecting tray. By virtue of the fact that the inventive fire bars have the material omission described, they differ significantly from the generic cuboid fire bars which have either a square or rectangular cross-sectional area. An omission in the context of the present invention is to be understood that the support edge does not extend to this facade when attaching the fire bolt element to a facade, but at a distance from this facade ends, so that the facade side or surface of the fire bolt element according to the invention in the direction from the bottom to the top along a portion of the thickness extension of the fire lock element has a smaller extent than in the area of the front or - area. Thus, in this embodiment, the collecting tray of the omission represents another part of the top of the fire bolt element according to the invention. Because this collecting tray is in conventional use, ie facing substantially horizontal orientation of the fire bolt element on a building facade of the building top. Accordingly, only by attaching the invention Brandriegelelements containing this omission to the building facade formed a trough or tub, which is open at the top, but no longer open to the façade side.
Gemäß einer weiteren zweckmäßigen Ausgestaltung schließt sich an den genannten Auflagerand eine, insbesondere wannenförmige, Vertiefung an. Im Sinne der vorliegenden Erfindung soll sich diese Vertiefung von der beschriebenen Auslassung dadurch unterscheiden, dass die Fassadenseite des erfindungsgemäßen Brandriegelelements von der Unterseite zur Oberseite im Wesentlichen über eine ähnliche oder identische Erstreckung verfügt wie die Frontfläche bzw. -seite von der Unter- bis zur Oberseite, d.h. bis zum Auflagerand. Demzufolge kann die Vertiefung eingefasst sein durch den bereits beschriebenen vorderen Auflagerand, auch frontseitiger Auflagerand genannt, und einen fassadenseitigen Auflagerand, der sich von der Fassadenseite bis zur Vertiefung erstreckt und der gegebenenfalls, jedoch nicht notwendigerweise, ebenfalls als Auflage für die Unterseite einer Wärmedämmplatte dienen kann.According to a further expedient refinement, a recess, in particular a trough-shaped depression, adjoins the abovementioned support edge. For the purposes of the present invention, this indentation is intended to differ from the described omission in that the facade side of the fire bolt element according to the invention has essentially the same or identical extent from the bottom to the top as the front surface or side from the bottom to the top ie to the Auflagerand. Accordingly, the recess may be bordered by the front bearing edge already described, also called the front bearing edge, and a facade side bearing edge extending from the facade side to the recess and may optionally, but not necessarily, also serve as a support for the underside of a thermal insulation board ,
Die Vertiefung wie auch die Auslassung können unterschiedliche Querschnittsformen aufweisen. Beispielsweise kann die Querschnittsform der Vertiefung im Querschnitt V-förmig, quadratisch, rechteckig, trapezförmig (d.h. hinterschnitten), kreisausschnittförmig oder in sonstiger Weise ausgestaltet sein, solange sie einem Auffangboden die Aufnahme von abgetropften geschmolzenen Dämmstoffmaterialresten im Brandfall gestattet und insbesondere diese Reste nicht im oberen Bereich der Begrenzungswand haften bleiben und/oder sich sammeln.The recess as well as the omission may have different cross-sectional shapes. For example, the cross-sectional shape of the recess in cross-section V-shaped, square, rectangular, trapezoidal (ie undercut), circular cut-out or otherwise configured as long as it allows a collecting tray to receive dripped molten Dämmstoffmaterialresten in case of fire and especially these residues not in the upper Adhere to the boundary wall and / or collect.
Die Vertiefung bzw. Auslassung des erfindungsgemäßen Brandriegelelements erstreckt sich vorzugsweise entlang der gesamten Längsausrichtung desselben.The depression or omission of the inventive fire-barrier element preferably extends along the entire longitudinal alignment thereof.
In einer besonders zweckmäßigen Ausgestaltung ist vorgesehen, dass der Auflagerand und die sich an diesen anschließende Frontfläche zumindest abschnittsweise im Wesentlichen rechtwinklig zueinander angeordnet sind. Die Frontfläche verläuft in der Regel nach Anbringung des Brandriegelelements an der Gebäudefassade im Wesentlichen parallel zu dieser.In a particularly expedient embodiment, it is provided that the support edge and the front surface adjoining thereto are arranged at least in sections essentially at right angles to one another. The front surface is usually after attachment of the fire bolt element on the building facade substantially parallel to this.
Bei den erfindungsgemäßen Brandriegelelementen erstreckt sich regelmäßig vom Auflagerand zum Auffangboden der Vertiefung bzw. der Auslassung eine Begrenzungswand. Diese Begrenzungswand verfügt in ihrem oberen Abschnitt, d.h. in dem sich an den Auflagerand anschließenden Abschnitt in Richtung zu dem Auffangboden vorzugsweise über eine durchschnittliche Erstreckung von mindestens 2 cm, insbesondere mindestens 3 cm und besonders bevorzugt mindestens 4 cm. In einer Ausführungsform der Erfindung kann sich an diesen oberen Abschnitt der Begrenzungswand im Wesentlichen unmittelbar der Auffangboden anschließen. Die Dimensionierung der Begrenzungswand in Richtung vom Auffangboden zum Auflagerand hängt dabei im Allgemeinen u.a. auch ab von der Dicke des geschäumten Dämmschichtmaterials, in das der erfindungsgemäße Brandriegel bzw. das erfindungsgemäße Brandriegelelement integriert ist und damit von der Menge an im Brandfall von der Auslassung bzw. der Vertiefung aufzunehmenden geschmolzenen geschäumten Dämmstoffrückständen. Die Tiefe der Vertiefung bzw. der Auslassung, d.h. die Erstreckung vom Auflagerand zum Auffangboden ist dabei regelmäßig derart zu wählen, dass im Brandfall von der dem Feuer ausgesetzten Dämmschicht abgetropfte schmelzflüssige bzw. auf- und/oder angeschmolzene Rückstände zu einem nicht unwesentlichen Teil aufgefangen werden, ohne dass im bzw. auf dem Auffangboden ein Sekundärbrand entsteht. Auf diese Weise werden die aufgefangenen Partikel in der Vertiefung oder der Auslassung nicht selber einen Brand von gegebenenfalls noch nicht verbranntem Dämmstoffmaterial oberhalb des Brandriegels entfachen und können zudem durch von unten aus einer Gebäudeöffnung austretende Flammen selber nicht in Brand gesetzt werden. Dadurch dass der Auflagerand von der eigentlichen, d.h. ungedämmten Gebäudefassade beabstandet ist, wird sich dort nur ein sehr geringer Anteil an aufgeschmolzenen und gegebenenfalls noch brennenden Schaumstoffresten sammeln können. Dieses Material ist durch die Beabstandung des Auflagerandes von der Fassade wie auch von dem Auffangboden selber wiederum soweit von möglicherweise aufschmelzbarem bzw. entflammbarem Material entfernt, dass die auf dem Auflagerand sich sammelnden Schmelzreste nicht mehr für eine Fortführung des Brandes zur Verfügung stehen. Der Auflagerand zeichnet sich demgemäß vorteilhafterweise dadurch aus, dass dieser als Auflagefläche hinreichend breit ist, damit sich darauf abgetropfte schmelzeflüssige bzw. auf- und/oder angeschmolzene Dämmmaterialreste sammeln können, ohne sogleich in die Vertiefung oder die Auslassung abzurutschen und dass darauf insbesondere auch Dämmmaterial, z.B. in Plattenform, bündig aufgelegt werden kann, um eine einfache und gleichzeitig wärmebrückenfreie Montage zu ermöglichen. Die alleinige durchgängige Abschrägung der Oberseite des Brandriegels von der Frontfläche bis zur Fassadenseite, beispielsweise unter einem Winkel von 45°, reicht nicht aus, um zu einem erfindungsgemäßen Brandriegel zu gelangen bzw. zu einem Brandriegel, mit dem sich die erfindungsgemäßen Effekte einstellen.In the case of the inventive fire-retardant elements, a boundary wall extends regularly from the supporting edge to the collecting base of the depression or the omission. This boundary wall has in its upper portion, ie in the adjoining the support edge portion in the direction of the collecting tray preferably via a average extension of at least 2 cm, in particular at least 3 cm and more preferably at least 4 cm. In one embodiment of the invention may connect to this upper portion of the boundary wall substantially directly the collecting tray. The dimensioning of the boundary wall in the direction of the collecting tray to the support edge generally depends, inter alia, on the thickness of the foamed Dämmschichtmaterials into which the invention Brandriegel or the inventive fire lock element is integrated and thus of the amount of fire in the case of the omission or the Well to be absorbed molten foamed insulation residues. The depth of the depression or the omission, ie the extent of the support edge to the collecting tray is to be chosen regularly such that in the event of fire from the exposed to the insulating layer insulation molten or up and / or molten residues are collected to a not insignificant part without a secondary fire being created in or on the collecting tray. In this way, the trapped particles in the recess or the omission will not itself ignite a fire of possibly not yet burned insulation material above the firing bolt and can not be set on fire even by emerging from below from a building opening flames. The fact that the support edge is spaced from the actual, ie non-insulated building facade, there will collect only a very small proportion of molten and possibly still burning foam remnants. This material is removed by the spacing of the Auflagerandes of the facade as well as the collecting tray itself again as far as possibly meltable or flammable material that collects on the support edge melting remnants are no longer available for a continuation of the fire. The support edge is accordingly advantageously characterized by the fact that it is sufficiently wide as a bearing surface so that it can collect melted liquid or fused and / or fused residues of insulating material without immediately slipping into the recess or the recess and in particular also insulating material, eg in plate form, can be placed flush, to allow easy and at the same time thermal bridge-free installation. The sole continuous beveling the top of the bolt from the front surface to the front side, for example, at an angle of 45 °, is not enough to get to a fire bar according to the invention or to a fire bar with which set the effects of the invention.
Es hat sich als zweckmäßig erwiesen, dass der Auflagerand und die sich an diesen anschließende Begrenzungswand zumindest in dem sich an diesen Auflagerand anschließenden oberen Abschnitt im Wesentlichen rechtwinklig zueinander angeordnet sind. Dieser obere Abschnitt kann auch hinterschnitten sein, kann jedoch ebenfalls geringfügig in Richtung der Fassadenseite geneigt sein, solange sichergestellt werden kann, dass an diesem oberen Bereich im Wesentlichen keine abtropfenden schmelzflüssigen bzw. auf- oder angeschmolzenen Dämmmaterialreste haften bleiben. In einer Ausführungsform der Erfindung kann dementsprechend insbesondere der obere Bereich der Begrenzungswand, vorzugsweise über eine Erstreckung von mindestens 2 cm, insbesondere von mindestens 3 cm und besonders bevorzugt von mindestens 4 cm, eine Neigung in Richtung der Fassadenseite in Bezug auf die Vertikale bei Anbringung an eine Gebäudefassade von maximal 10°, vorzugsweise maximal 5°, aufweisen.It has proven to be expedient that the support edge and the adjoining boundary wall are arranged substantially at right angles to one another, at least in the upper section adjoining this support edge. This upper portion may also be undercut, but may also be slightly inclined in the direction of the facade side, as long as it can be ensured that remain adhering to this upper area substantially no dripping molten or melted or fused Dämmmaterialreste. Accordingly, in one embodiment of the invention, in particular, the upper region of the boundary wall, preferably over an extension of at least 2 cm, in particular of at least 3 cm and more preferably of at least 4 cm, a slope in the direction of the facade side with respect to the vertical when attached to a building facade of a maximum of 10 °, preferably a maximum of 5 °.

In einer geeigneten Ausführungsform kann vorgesehen sein, dass das erfindungsgemäße Brandriegelelement eine durchschnittliche Höhe (gemessen von der Unterseite zu dem Auflagerand) von mindestens 8 cm, vorzugsweise mindestens 15 cm und besonders bevorzugt mindestens 18 cm und/oder eine durchschnittliche Dicke (gemessen von der Fassadenseite zu der Frontfläche) von mindestens 5 cm, vorzugsweise mindestens 8 cm und besonders bevorzugt mindestens 10 cm aufweist.In a suitable embodiment it can be provided that the inventive fire-barrier element has an average height (measured from the underside to the support edge) of at least 8 cm, preferably at least 15 cm and particularly preferably at least 18 cm and / or an average thickness (measured from the facade side to the front surface) of at least 5 cm, preferably at least 8 cm and more preferably at least 10 cm.
Ferner kann vorgesehen sein, dass die Begrenzungswand und der sich hieran anschließende Auffangboden im Wesentlichen einen rechten Winkel bilden.Furthermore, it can be provided that the boundary wall and the collecting tray adjoining thereto form essentially a right angle.
Des Weiteren kann vorgesehen sein, dass der Übergang von Begrenzungswand zu Auffangboden abgeschrägt oder abgerundet ausgebildet ist. Bei dieser Ausführungsform der Erfindung wirkt das gegenüber einer vertikalen Begrenzungswand zusätzlich insbesondere im Übergang von Begrenzungswand zu Auffangboden vorliegende Material stabilisierend auf die Gesamtstruktur und erlaubt mehr Freiheitsgrade bei der Dimensionierung, ohne dass Zugeständnisse hinsichtlich der weiteren erfindungsgemäßen Effekte gemacht werden müssen.Furthermore, it can be provided that the transition from boundary wall to collecting base is chamfered or rounded. In this embodiment of the invention, the material present in relation to a vertical boundary wall, in particular in the transition from the boundary wall to the collecting base, has a stabilizing effect on the overall structure and allows more degrees of freedom in the dimensioning without having to make concessions with regard to the further effects according to the invention.
Ferner kann vorgesehen sein, dass mindestens der obere Abschnitt der Begrenzungswand in der Art ausgerichtet ist, dass dieser bei Anbringung des Brandriegelelements an eine Gebäudefassade im Wesentlichen parallel zu dieser verläuft oder sich von dieser, beginnend mit dem Auflagerand, entfernt oder dass mindestens der obere Abschnitt der Begrenzungswand in der Art ausgerichtet ist, dass dieser im Wesentlichen parallel zu der Verlängerung der Fassadenseite verläuft oder sich von dieser Verlängerung, beginnend mit dem Auflagerand, entfernt.Furthermore, it can be provided that at least the upper portion of the boundary wall is aligned in such a way that it runs when attaching the fire bolt element to a building facade substantially parallel to this or away from this, starting with the support edge, or that at least the upper portion the boundary wall is aligned in such a way that it runs substantially parallel to the extension of the facade side or away from this extension, starting with the support edge.
Des Weiteren sind solche erfindungsgemäßen Brandriegelelemente bevorzugt, bei denen die Erstreckung der Begrenzungswand, insbesondere die Erstreckung des oberen Bereichs der Begrenzungswand, zu der Frontfläche kleiner oder gleich der Erstreckung des Auffangbodens von der Fassadenseite in Richtung der Frontfläche ist.Furthermore, such inventive fire lock elements are preferred in which the extent of the boundary wall, in particular the extent of the upper region of the boundary wall, to the front surface is less than or equal to the extension of the collecting tray from the facade side in the direction of the front surface.
Des Weiteren können bei dem erfindungsgemäßen Brandriegelelement der Auflagerand, die Frontfläche, der Auffangboden, die Begrenzungswand und/oder die Unterseite, insbesondere der Auffangboden und/oder die Begrenzungswand, zumindest bereichsweise mindestens eine Beschichtung, insbesondere eine mineralische Beschichtung, z.B. eine Putzschicht aufweisen.Furthermore, in the case of the inventive fire-barrier element, the support edge, the front surface, the collecting base, the boundary wall and / or the underside, in particular the collecting base and / or the boundary wall, at least in regions at least one coating, in particular a mineral coating, e.g. have a plaster layer.
Besonders bevorzugt sind solche erfindungsgemäßen Brandriegelelemente, bei denen die maximale Erstreckung der Vertiefung bzw. Auslassung von dem Auflagerand zu dem Auffangboden mindestens 1/5, vorzugsweise mindestens 2/5 und besonders bevorzugt nicht mehr als 3/5 der Höhe des Brandriegelelements bzw. des Brandriegels umfasst.Particularly preferred are such Brandriegelelemente invention, in which the maximum extent of the depression or omission of the support edge to the collecting tray at least 1/5, preferably at least 2/5 and more preferably not more than 3/5 of the height of the fire bolt element or the fire bar includes.
Bei einer weiteren Ausgestaltung des erfindungsgemäßen Brandriegelelements kann vorgesehen sein, dass die Vertiefung oder die Auslassung mindestens teilweise, insbesondere im Wesentlichen vollständig, mit mindestens einem wärmeschrumpfbaren Material, insbesondere mit geschäumtem Styrolpolymerisat, ausgefüllt ist, das vorzugsweise eine maximale Wärmeleitung von 0,060 W/mK aufweist. Selbst wenn die Vertiefung oder Auslassung, anders als das Brandriegelelement selber, mit einem wärmeschrumpfbaren Material ausgefüllt ist und das Gesamtbauteil dadurch eine quadratische oder rechteckige Querschnittsfläche bildet, liegt noch stets eine Auslassung oder Vertiefung im Sinne der Erfindung vor. Denn sobald der Brandfall eintritt, wird die Auslassung bzw. Vertiefung freigegeben und kann damit ihre erfindungsgemäße Wirkung erfüllen.In a further embodiment of the inventive fire-retardant element it can be provided that the depression or the extention is at least partially, in particular substantially completely, filled with at least one heat-shrinkable material, in particular foamed styrene polymer, which preferably has a maximum heat conduction of 0.060 W / mK , Even if the depression or omission, unlike the fire barrier element itself, is filled with a heat-shrinkable material and the overall component thereby forms a square or rectangular cross-sectional area, there is still an omission or depression within the meaning of the invention. Because as soon as the fire occurs, the omission or depression is released and can thus fulfill their effect according to the invention.
Hierbei kann vorgesehen sein, dass auf dem wärmeschrumpfbaren Material eine nicht oder nur schwer entflammbare Schicht aufliegt, die über eine größere Wärmeleitfähigkeit verfügt als das wärmeschrumpfbare Material.It can be provided that rests on the heat-shrinkable material, a non-flammable or only flammable layer, which has a greater thermal conductivity than the heat-shrinkable material.
Die der Erfindung zugrunde liegende Aufgabe wird ferner gelöst durch einen Brandriegel umfassend mindestens zwei, insbesondere eine Vielzahl an erfindungsgemäßen Brandriegelelementen.The object underlying the invention is further achieved by a fire bar comprising at least two, in particular a plurality of fire bar elements according to the invention.
Hierbei hat es sich als bevorzugt erwiesen, solche erfindungsgemäßen Brandriegelelemente über ihre Seitenflächen unter Ausbildung eines erfindungsgemäßen Brandriegels aneinanderzureihen, die über eine im Wesentlichen einheitliche Querschnittsform verfügen sowie insbesondere auch über einen einheitlichen Querschnitt der Vertiefung bzw. Auslassung, so dass eine einheitliche Vertiefung bzw. Auslassung entlang des gesamten Brandriegels gebildet wird.In this case, it has proven to be preferable to arrange such inventive fire-barrier elements over their side surfaces to form a fire bar according to the invention, which have a substantially uniform cross-sectional shape and, in particular, a uniform cross-section of the depression or omission, so that a uniform recess or omission is formed along the entire fire bar.
Die erfindungsgemäßen Brandriegelelemente bzw. der erfindungsgemäße Brandriegel können als, insbesondere horizontale, Brandsperre in Wärmedämmverbundsystemen für Gebäudefassaden verwendet werden. Die erfindungsgemäßen Effekte stellen sich nicht nur bei horizontaler Anbringung, sondern ebenfalls auch noch dann ein, wenn die erfindungsgemäßen Brandriegelelemente und erfindungsgemäßen Brandriegel eine von der horizontalen Ausrichtung abweichende, beispielsweise schräg, nicht jedoch vertikal verlaufende, Ausrichtung besitzen.The fire-barrier elements according to the invention or the fire-barrier according to the invention can be used as, in particular horizontal, fire barriers in external thermal insulation systems for building facades. The effects according to the invention arise not only in the case of horizontal attachment, but also also when the inventive fire-retardant elements and inventive fire-retardants have a different orientation than, for example, oblique, but not vertical, alignment.
Des Weiteren können die erfindungsgemäßen Brandriegelelemente bzw. der erfindungsgemäße Brandriegel dazu verwendet werden, Gebäudeöffnungen wie Fenster oder Türen selektiv zu erfassen. Das erfindungsgemäße Brandriegelelement bzw. der erfindungsgemäße Brandriegel können folglich, insbesondere bei Anbringung in horizontaler Ausrichtung, im Bereich oberhalb von Stürzen, insbesondere Tür- und/oder Fensterstürzen, bzw. oberhalb von Gebäudeöffnungen, insbesondere Tür- und/oder Fensteröffnungen, angeordnet sein.Furthermore, the inventive fire bolt elements or the fire bolt according to the invention can be used to building openings such as windows or doors selectively detect. The inventive fire lock element or the inventive fire bars can consequently, in particular when mounted in a horizontal orientation, be arranged in the area above falls, in particular door and / or window lintels, or above building openings, in particular door and / or window openings.
Bevorzugt wird mit dem erfindungsgemäßen Brandriegel eine, insbesondere im Wesentlichen durchgängige, Unterbrechung einer Fassadendämmung umfassend oder bestehend aus geschäumten Styrolpolymerisaten verwirklicht.Preferably, with the inventive fire bars a, in particular substantially continuous, interruption of a facade insulation comprising or consisting of foamed styrene polymers realized.
Mit den erfindungsgemäßen Brandriegelelementen bzw. dem erfindungsgemäßen Brandriegel gelingt eine Ver- bzw. Behinderung einer geschossübergreifenden Brandweiterleitung in der Dämmebene von Wärmedämmverbundsystemen umfassend oder bestehend aus geschäumten Styrolpolymerisaten.With the inventive fire-barrier elements or the fire-barrier according to the invention, it is possible to obstruct or obstruct a fire-propagating fire in the insulating layer of composite thermal insulation systems comprising or consisting of foamed styrene polymers.
Des Weiteren wird die der Erfindung zugrunde liegende Aufgabe gelöst durch ein Wärmedämmverbundsystem umfassend oder bestehend aus geschäumten Styrolpolymerisaten für eine Gebäudefassade, umfassend mindestens ein erfindungsgemäßes Brandriegelelement oder mindestens einen erfindungsgemäßen Brandriegel. Außerdem wird die der Erfindung zugrunde liegende Aufgabe gelöst durch eine Gebäudefassade umfassend mindestens ein erfindungsgemäßes Brandriegelelement oder einen erfindungsgemäßen Brandriegel oder ein erfindungsgemäßes Wärmedämmverbundsystem. In einer zweckmäßigen Ausgestaltung kann die Frontfläche des Brandriegelelements bzw. des Brandriegels im Wesentlichen bündig mit der Frontseite des Wärmedämmverbundsystems bzw. der Gebäudefassade abschließen oder bündig hierin integriert sein. Daneben ist es ebenfalls möglich, das erfindungsgemäße Brandriegelelement oder den erfindungsgemäßen Brandriegel als Gesims auszugestalten bzw. die Frontfläche mit Ornamenten zu versehen.Furthermore, the object underlying the invention is achieved by a composite thermal insulation system comprising or consisting of foamed styrene polymers for a building facade, comprising at least one inventive fire lock element or at least one inventive fire bars. In addition, the object underlying the invention is achieved by a building facade comprising at least one inventive Brandriegelelement or a fire bar according to the invention or an inventive thermal insulation composite system. In an expedient embodiment, the front surface of the fire bolt element or of the fire bolt can be substantially flush with the front side of the external thermal insulation composite system or the building facade or integrated flush therein. In addition, it is also possible to design the inventive fire lock element or the fire bar according to the invention as a cornice or to provide the front surface with ornaments.
Das erfindungsgemäße Brandriegelelement bzw. der erfindungsgemäße Brandriegel können über die Fassadenseite unmittelbar oder mittelbar an einer Gebäudeaußenwand mittels mindestens eines mineralischen Klebers und/oder organischen Klebers und/oder mittels Dübel oder im Wege von Halteschienen angebracht werden.The inventive fire lock element or the inventive fire bars can be mounted on the facade side directly or indirectly to a building exterior wall by means of at least one mineral adhesive and / or organic adhesive and / or by means of dowels or by way of support rails.
Mit den erfindungsgemäßen Brandriegelelementen bzw. mit dem erfindungsgemäßen Brandriegel geht der überraschende Vorteil einher, dass im Fall eines Brandes von insbesondere unverputzten Fassaden mit einem Wärmedämmverbundsystem enthaltend Wärmedämmmaterialien auf Basis von Styrolpolymerisaten ein deutlich geringerer Anteil des auf der Oberseite des erfindungsgemäßen Brandriegelelements/Brandriegels gesammelten geschmolzenen Styrolpolymerisats verbrennen kann. Hierdurch wird die Brandlast oberhalb des Brandriegelelements/Brandriegels erheblich vermindert. Bei einer beispielsweise dem Feuer ausgesetzten unverputzten Fassade umfassend eine Wärmedämmung aus geschäumten Styrolpolymerisaten entziehen die erfindungsgemäßen Brandriegelelemente/Brandriegel abtropfendes, geschmolzenes Styrolpolymerisat zu einem Großteil dem Feuer, so dass sich ein möglicher Sekundärbrand auf dem Brandriegel nicht bilden bzw. nicht ausbreiten kann. Hierdurch werden dem Feuer zuvor nicht zugängliche Stellen in der Fassade nicht im nachhinein entzündet.The novel fire bar elements or with the fire bar according to the invention has the surprising advantage that, in the case of a fire of, in particular, unpainted facades with a thermal insulation composite system containing thermal insulation materials based on styrene polymers, a significantly lower proportion of the molten styrene polymer collected on the upper side of the inventive fire-retainer / fire bar can burn. As a result, the fire load is significantly reduced above the fire bolt element / fire bar. In an example exposed to the fire exposed facade comprising a thermal insulation of foamed styrene polymers fire marker elements / fire bars according to the invention withdraw dripping, molten styrene polymer to a large extent the fire, so that a possible secondary fire on the fire bar does not form or can not spread. As a result, previously inaccessible places in the facade are not ignited in retrospect.
Dieses wird bei dem erfindungsgemäßen Brandriegelelement/Brandriegel durch die Verwendung mindestens zweier, voneinander getrennter Auffangbereiche für oberhalb des Brandriegels aufschmelzendes und abtropfendes Dämmmaterial, insbesondere Styrolpolymerisat, bewerkstelligt. Denn nur der Auflagerand als einer dieser Auffangbereiche steht für die Entfachung eines Sekundärbrandes überhaupt zur Verfügung. Auf diesem Auflagerand wird jedoch aufgrund des Abstandes zur Fassade nur der weitaus geringere Teil des abgeschmolzenen und abtropfenden Styrolpolymerisats aufgefangen. Sofern es überhaupt an auf diesem Auflagerand zu einem Sekundärbrand des dort aufgegangenen abgetropften geschäumten Dämmmaterials, insbesondere Styrolpolymerisats kommt, verlöscht dieser in der Regel von selbst, ohne weiteren Schaden anrichten zu können. Denn der Abstand zu der Fassadenseite ist durch die in dem erfindungsgemäßen Brandriegelelement/Brandriegel vorgesehene, sich an den Auflagerand fassadenseitig anschließende Vertiefung bzw. Auslassung zu groß. Im Übrigen hat sich herausgestellt, dass sich ohnehin die weitaus größte Menge bei einem brandbedingten Abtropfen des oberhalb des erfindungsgemäßen Brandelements/Brandriegels aufgeklebten flammgeschützten geschäumten Dämmmaterialien, z.B. eines Styrolpolymerisathartschaums in der Vertiefung bzw. Auslassung bzw. deren Auffangboden sammelt. Insbesondere bei Verwendung einer Auslassung hat sich als besonders vorteilhaft erwiesen, dass der Wand- bzw. Fassadenbereich benachbart zu der Auslassung durch den frontseitigen Bereich hinreichend abgeschirmt wird, so dass dieser Bereich der Fassade bzw. der Wand relativ kühl bleibt und für die Abgabe von Wärmeenergie von in die Auslassung getropften schmelzflüssigen bzw. auf- und/oder angeschmolzenen Dämmmaterials, z.B. Styrolpolymerisatresten genutzt werden kann, wodurch letztere, sollten sie selber noch brennen, schnell verlöschen oder, sofern diese nicht selber brennen, eine Selbstentzündung verhindert wird.This is accomplished by the use of at least two, separate collection areas for above the firing bar melting and dripping insulation material, in particular styrene polymer in the inventive fire bar element / fire bars. Because only the Auflagerand as one of these catchment areas is available for the kindling of a secondary fire at all. However, due to the distance from the facade, only the much smaller part of the molten and dripping styrene polymer is collected on this support edge. If it comes at all on this support sand to a secondary firing of the dropped there foamed insulation material, in particular styrene polymer, this usually extinguishes by itself, without being able to cause further damage. Because the distance to the façade side is too large by the provided in the fire bolt element / Brandriegel invention, on the support edge facade side subsequent depression or omission. Incidentally, it has been found that by far the greatest amount accumulates in the event of fire-induced dripping of the flame-retardant foamed insulation materials pasted above the fire element / firearm according to the invention, for example of a styrene polymer foam in the depression or omission or its collecting base. In particular, when using an omission has proved to be particularly advantageous that the wall or facade area adjacent to the omission is adequately shielded by the front area, so that this area of the facade or the wall remains relatively cool and for the release of heat energy can be used by dripping into the omission molten or fused and / or fused insulating material, eg Styrolpolymerisatresten, whereby the latter should they themselves burn, quickly extinguish or, if they do not burn themselves, prevent spontaneous combustion.
Mit der Anbringung der erfindungsgemäßen Brandriegelelemente bzw. Brandriegel soll sich somit außerdem die Brandgefahr während des kurzen Zeitraums minimieren lassen, in dem das Wärmedämmverbundsystem in unverputztem Zustand ist.In addition, with the attachment of the inventive fire lock elements or fire bars, the risk of fire during the short period should be minimized, in which the thermal insulation system is in an uncleaned state.
Es hat sich auch als besonders vorteilhaft erwiesen, dass zumindest der obere Bereich der Begrenzungswand hinreichend steil ausgeführt wird, so dass daran keine brennbaren Materialien haften bleiben bzw. sich dort ansammeln können, sondern diese im Regelfall von dem Auffangboden der Auslassung bzw. Vertiefung aufgenommen werden. Besonders zweckmäßig ist dabei zumindest der obere Bereich der Begrenzungswand vertikal ausgerichtet oder weist sogar einen Hinterschnitt auf. Wie sich nun gezeigt hat, führt der kontrollierte Sekundärbrand der geschmolzenen Styrolpolymerisatreste auf dem Auflagerand dazu, dass aufgeschmolzenen Resten in der Auslassung bzw. Vertiefung Sauerstoff entzogen wird. Zudem führt die durch diesen kontrollierten Sekundärbrand auf dem Auflagerand verursachte Luftströmung in demjenigen Teil des Brandriegels, der der Fassade zugewandt ist, insbesondere in der Vertiefung bzw. der Auslassung zu einer Abkühlung des dort aufgefangenen geschmolzenen Dämmmaterialien, z.B. eines Styrolpolymerisats. Diese Luftströmung hat zudem den überraschenden vorteilhaften Effekt, dass selbst auf dem Auflagerand im Bereich des Übergangs vom Auflagerand zur Begrenzungswand der Vertiefung bzw. Auslassung und im Bereich des Übergangs vom Auflagerand zur Frontfläche aufliegende aufgeschmolzene Styrolpolymerisatreste schneller abkühlen und verlöschen.It has also proven to be particularly advantageous that at least the upper region of the boundary wall is made sufficiently steep, so that it can adhere to any combustible materials or accumulate there, but they are usually absorbed by the collection tray of the omission or depression , Particularly expediently, at least the upper region of the boundary wall is aligned vertically or even has an undercut. As has now been shown, the controlled secondary firing of the molten styrene polymer residues on the support edge causes oxygen to be removed from molten residues in the recess. In addition, the air flow caused by this controlled secondary firing on the support edge in that part of the firestop facing the façade, in particular in the depression or extinction, leads to a cooling of the molten insulating materials intercepted there, e.g. a styrene polymer. This air flow also has the surprisingly advantageous effect that even on the support edge in the region of the transition from the support edge to the boundary wall of the depression or omission and in the region of the transition from the support edge to the front surface resting molten Styrolpolymerisatreste cool faster and extinguish.
Durch die Auftragung einer, insbesondere mineralischen, Beschichtung kann der Kühleffekt nochmals erhöht werden. Auch kann hierdurch die Erwärmung der Auslassung bzw. der Vertiefung von der Unterseite verzögert werden. Durch den Einsatz einer solchen Beschichtung lässt sich die Höhe des Brandriegels geringer dimensionieren. Hierdurch entsteht ein größerer Gestaltungsspielraum. Es hat sich als ausreichend bzw. besonders vorteilhaft erwiesen, wenn wenigstens die Begrenzungswand und der Auffangboden mit der genannten mineralischen Beschichtung versehen werden.By applying a, in particular mineral, coating, the cooling effect can be increased again. Also, this can delay the heating of the omission or depression from the bottom. By using such a coating, the height of the fire bar can be made smaller. This creates a greater freedom of design. It has proven to be sufficient or particularly advantageous if at least the boundary wall and the collecting tray are provided with said mineral coating.
Wird die Vertiefung bzw. die Auslassung mit einem Styrolpolymerisat mit ausgeprägtem Wärmeschrumpf ausgefüllt, kann eine mögliche Konvektion in der in einem Wärmedämmverbundsystem integrierten Auslassung bzw. Vertiefung verhindert und die Wärmedämmung des Brandriegels nochmals verbessert werden. Kommt es zu einem Primärbrand vor der unverputzten Fassade, schrumpft und/oder schmilzt dieses in die Auslassung bzw. Vertiefung eingesetzte Formstück unmittelbar zusammen, so dass sich die gewünschte Auffangwanne automatisch bildet, bevor und während geschmolzenes geschäumten Dämmmaterialien wie Styrolpolymerisaten von dem darüberliegenden Dämmmaterial bzw. Polystyrolhartschaum abtropft. Gegenüber herkömmlichen Brandriegeln geht mit der Erfindung des Weiteren der überraschende Vorteil einher, dass geschmolzenes geschäumtes Dämmmaterial, z.B. Styrolpolymerisat bei einem Primärbrand vor einer unverputzten Fassade in zwei Bereichen bei gleichzeitigem Schutz der größeren, aufgefangenen Menge vor späterer Entzündung geschützt werden kann.If the depression or the omission is filled with a styrene polymer having a pronounced heat shrinkage, possible convection in the recess or recess integrated in a thermal insulation composite system can be prevented and the thermal insulation of the bolt to be further improved. If a primary firing takes place in front of the unpainted facade, this shaped piece inserted into the recess or recess immediately shrinks, so that the desired collecting tray automatically forms before and while molten foamed insulation materials such as styrene polymers are removed from the overlying insulating material or Polystyrene foam drips. Compared to conventional fire bars, the invention also has the surprising advantage that molten foamed insulating material, eg styrene polymer, can be protected from a spontaneous facade in two areas while simultaneously protecting the larger, collected amount against later ignition in a primary fire.

Die
Mit den erfindungsgemäßen Brandriegelelementen bzw. den daraus gebildeten Brandriegeln, können, wie gezeigt werden konnte, Gebäudefassaden, welche mit Wärmdämmverbundsystemen auf der Basis von geschäumten Dämmmaterialien, insbesondere Styrolpolymerisaten wie Polystyrol ausgestattet sind, wirksam vor einer Brandweiterleitung geschützt werden bzw. eine solche Brandweiterleitung kann in signifikantem Umfang zurückgedrängt, d.h. behindert werden.As could be shown, building façades, which are equipped with thermal insulation composite systems based on foamed insulation materials, in particular styrene polymers such as polystyrene, are effectively protected against fire propagation with the inventive fire barrier elements or the fire bolts formed therefrom or such fire forwarding can be suppressed to a significant extent, ie obstructed.
