Abstract

Metal framework for windows and doors is made of aluminium profile with closed or open hollow chambers into which thermal set, hydrophilic adsorbent material is packed. The middle part of the framework is made of aluminium which has a stamped pattern (12, 13) in order to reduce the heat flow through it.

Description

Die Erfindung bezieht sich auf ein Rahmenwerk aus Metallprofilen in Brandschutzausführung für Fenster, Türen, Fassaden oder Glasdächer.The invention relates to a framework made of metal profiles in fire protection for windows, doors, facades or glass roofs.

Es ist eine mit einer Verglasung versehene Schutztür gegen Feuer und Rauch bekannt (DE 29 48 039 A1), bei der die Rahmenprofile aus zwei Stahlrohren gebildet werden, zwischen denen eine Wärmedämmung aus nicht brennbarem Material angeordnet ist. Die Verbindung der beiden Stahlrohre erfolgt durch Bolzen bzw. Schrauben. Die Stahlrohre halten den im Brandfall auftretenden Temperaturen stand. Die Wärmedämmung zwischen den Stahlrohren eines Rahmenprofils hat lediglich die Aufgabe, eine Temperaturerhöhung an der dem Brand abgewandten Seite über ein in Normen vorgegebenes Maß zu vermeiden. Bei diesem Konstruktionsprinzip kommen zumindest an der dem Brand zugewandten Seite Werkstoffe zum Einsatz, deren Schmelzpunkt höher liegt als die zu erwartenden Brandtemperaturen gemäß der in den Normen festgelegten Einheitstemperaturkurve.A glazed protective door against fire and smoke is known (DE 29 48 039 A1), in which the frame profiles are formed from two steel tubes between which thermal insulation made of non-combustible material is arranged. The two steel pipes are connected by bolts or screws. The steel pipes withstand the temperatures that arise in the event of a fire. The thermal insulation between the steel pipes of a frame profile only has the task of avoiding a temperature increase on the side facing away from the fire by a measure specified in standards. With this design principle, at least on the side facing the fire, materials are used whose melting point is higher than the expected fire temperatures according to the standard temperature curve specified in the standards.

Die Rahmenprofile nach der DE 29 48 039 A1 weisen Aluminium-Abdeckschalen auf, durch die der Eindruck eines Aluminiumbauelementes vermittelt werden soll. Diese Aluminium-Abdeckschalen schmelzen im Brandfall.The frame profiles according to DE 29 48 039 A1 have aluminum cover shells, through which the impression of an aluminum component is to be given. These aluminum covers melt in the event of a fire.

Bei der bekannten Türkonstruktion ist nachteilig, daß unterschiedliche Materialien im Rahmenprofil zusammengeführt werden, wobei der Stahlanteil ein hohes Gewicht ergibt. Die unterschiedlichen Materialien erfordern unterschiedliche Verarbeitungs- und Fügeverfahren. Zudem ist die Verkleidung mit Aluminium-Abdeckschalen aufwendig.In the known door construction, it is disadvantageous that different materials are brought together in the frame profile, the steel content giving a high weight. The different materials require different processing and joining processes. In addition, the cladding with aluminum covers is complex.

Der Erfindung liegt die Aufgabe zugrunde, ein Rahmenwerk aus Metallprofilen in Brandschutzausführung so zu gestalten, daß auf der dem Brand zugewandten Seite tragende Leichtmetallprofile, vorzugsweise Aluminiumprofile, eingesetzt werden können, deren Schmelzpunkt niedriger liegt als die im Brandfall zu erwartende, die Metallprofile beaufschlagende Temperatur und ein vollständiges Abschmelzen dieser tragenden Leichtmetallprofile über eine vorgegebene Sicherheitszeitdauer verhindert wird.The invention has for its object to design a framework made of metal profiles in fire protection design so that on the side facing the fire bearing light metal profiles, preferably aluminum profiles, can be used, the melting point of which is lower than the expected temperature and the metal profiles in the event of fire a complete melting of these load-bearing light metal profiles is prevented over a predetermined safety period.

Diese Aufgabe wird erfindungsgemäß bei einem Rahmenwerk der eingangs genannten Art dadurch gelöst, daß die Metallprofile drei Innenkammern aufweisen, eine mittlere Innenkammer bildende Metalleisten zur Herabsetzung des Wärmedurchflusses mit Ausstanzungen versehen oder anstelle der Metalleisten mehrteilige Isolierleisten vorgesehen sind und in den durch Wandungen aus Aluminium begrenzten übrigen Innenkammern Brandschutzplatten angeordnet sind.This object is achieved in a framework of the type mentioned in that the metal profiles have three inner chambers, metal strips forming a central inner chamber to reduce the heat flow with punched holes or multi-part insulating strips are provided instead of the metal strips and in the others delimited by walls made of aluminum Inner chambers fire protection panels are arranged.

Bei einer erfindungsgemäßen Ausführung sind die mit drei Innenkammern versehenen Metallprofile als einstückige, stranggepreßte Aluminiumprofile ausgebildet, in die im mittleren Bereich Löcher eingestanzt sind.In an embodiment according to the invention, the metal profiles provided with three inner chambers are designed as one-piece, extruded aluminum profiles, into which holes are punched in the central area.

Es ist vorteilhaft, im Beschlagfalz zwischen Blend- und Flügelrahmen einer Tür jeweils vor der gelochten Metalleiste einen Brandschutzstreifen aus unter Temperaturbelastung aufblähendem Material anzuordnen.It is advantageous to arrange a fire protection strip made of material that expands under temperature stress in the fitting rebate between the frame and the sash of a door in front of the perforated metal strip.

Der Brandschutzstreifen hat zum einen die Aufgabe, die gelochte Metalleiste vom sichtbaren Falz her abzudecken und andererseits im Brandfall dafür zu sorgen, daß der Falzraum weitgehendst durch aufblähendes Material geschlossen wird, um ein Durchtreten von Brandgasen zu verhindern.The fire protection strip has the task, on the one hand, of covering the perforated metal strip from the visible fold and, on the other hand, in the event of fire, of ensuring that the rebate space is largely closed by inflating material in order to prevent the passage of fire gases.

Die Metallprofile können als Verbundprofile ausgebildet sein und sich aus stranggepreßten Aluminium-Hohlkammerprofilen und aus einem Mittelteil aus Metall zusammensetzen, in dem der Wärmefluß gegenüber den aus Aluminium hergestellten Außenteilen herabgesetzt ist.The metal profiles can be designed as composite profiles and composed of extruded aluminum hollow chamber profiles and a central part made of metal, in which the heat flow is reduced compared to the outer parts made of aluminum.

An den Außenseiten oder/und an den Innenseiten der aus Aluminium gefertigten Metallprofile können diese abdeckende Platten oder sonstige Formkörper aus einem wärmebindenden, hydrophilen Adsorbens mit hohem Wasseranteil oder ein wärmebindendes, hydrophiles Adsorbens mit hohem Wasseranteil enthaltende Platten oder sonstige Formkörper befestigt sein.On the outer sides and / or on the inner sides of the metal profiles made of aluminum, these covering plates or other shaped bodies made of a heat-binding, hydrophilic adsorbent with a high water content or a heat-binding, hydrophilic adsorbent with a high water content can be attached or other shaped bodies.

Die Platten oder sonstigen Formkörper aus einem wärmebindenden, hydrophilen Adsorbens mit hohem Wasseranteil bestehen vorteilhaft aus Alaun und Gips.The plates or other shaped bodies made of a heat-binding, hydrophilic adsorbent with a high water content advantageously consist of alum and gypsum.

Beim Alaun handelt es sich um sog. Metalldoppelsalze, die in der Lage sind, in sehr hohem Grad gewichtsbezogen Kristallwasser zu speichern.The alum is a so-called metal double salt, which is able to store crystal water to a very high degree by weight.

Es hat sich als zweckmäßig erwiesen, Kalium-Alaun zu verwenden, das chemisch als Kalium-Aluminium-Sulfat-12-Hydrat zu bezeichnen ist. Die chemische Formel lautet:

        KA1(SO4)2x12 H2O.

It has proven to be expedient to use potassium alum, which can be referred to chemically as potassium aluminum sulfate 12 hydrate. The chemical formula is:

KA1 (SO 4 ) 2 x12 H 2 O.

Dieses Kalium-Alaun ist in der Lage, ca 45 Prozent Kristallwasser pro Gewichtseinheit physikalisch zu binden. Das Freisetzen des Kristallwassers aus dem Kalium-Alaun in reiner Form erfolgt bei 72 °C.This potassium alum is able to physically bind about 45 percent water of crystallization per unit weight. The crystal water is released from the potassium alum in pure form at 72 ° C.

Aufgrund der Dichte des Alauns von 1,1 g/cm3 ergibt sich volumenbezogen ein Anteil des eingelagerten Kristallwassers von ca. 50 Prozent.Due to the density of the alum of 1.1 g / cm 3 , the volume of the stored crystal water is approx. 50 percent.

Das Kalium-Alaun kann in eine Gipsmatrix eingebettet werden und verhält sich bezüglich der Aushärtung des Gipses völlig neutral, so daß die daraus hergestellten Platten, Formteile und Profile ausreichende Stabilität für ihre Anwendung im Brandschutz besitzen.The potassium alum can be embedded in a gypsum matrix and behaves completely neutrally with regard to the hardening of the gypsum, so that the plates, moldings and profiles produced therefrom have sufficient stability for their use in fire protection.

Das Kalium-Alaun verändert die Abbindeeigenschaften des Gipses nicht. Durch den Gips wiederum wird auch nicht die physikalische Wasseraufnahme des Alauns beeinträchtigt.The potassium alum does not change the setting properties of the plaster. The plaster in turn does not affect the physical water absorption of the alum.

Die Platten oder sonstigen Formteile, die mit einem hydrophilen Adsorbens versehen sind, bestehen vorzugsweise zu 50 Prozent aus einem modifizierten Gips und zu 50 Prozent aus Kalium-Alaun.The plates or other molded parts which are provided with a hydrophilic adsorbent preferably consist of 50 percent modified gypsum and 50 percent potassium alum.

Da der Gips wie auch das Alaun eine Dichte von 1,1 g/cm3 haben, ist dieses Verhältnis gewichts- wie auch volumenbezogen.Since the gypsum and the alum have a density of 1.1 g / cm 3 , this ratio is based on weight and volume.

Der Energieverzehr eines solchen Bauteiles beträgt ca. 1.100 j/cm3.The energy consumption of such a component is approximately 1,100 j / cm 3 .

Je nach dem Einsatzfall kann das Mischungsverhältnis zwischen Alaun und Gips variiert werden. Bei einem Mischungsverhältnis von 50 : 50 zwischen Gips und Alaun ergibt sich ein Anteil des eingelagerten Kristallwassers von 32 Prozent.Depending on the application, the mixing ratio between alum and plaster can be varied. With a mixing ratio of 50:50 between gypsum and alum, there is a 32 percent share of the stored crystal water.

Obwohl Kalium-Alaun für sich allein eine Wirktemperatur von 73 °C hat, wird die Wirktemperatur in Verbindung mit dem Gips auf einen höheren Wert, nämlich ca. 85 °C verlegt. Dies ergibt sich daraus, daß das im Alaun frei werdende Wasser durch einfaches Aufsaugen durch den Gips bis zur Temperatur von 85 °C gehalten wird, bevor es in die Dampfphase überführt wird.Although potassium alum has an effective temperature of 73 ° C by itself, the effective temperature in connection with the gypsum is increased to a higher value, namely approx. 85 ° C. This results from the fact that the water released in the alum is held up to a temperature of 85 ° C. by simply sucking it up through the plaster before it is converted into the vapor phase.

Es tritt hier eine günstige Wirktemperatur ein, die in ausreichender Distanz zu den Gebrauchstemperaturen liegt, die u.U. 70 °C bei direkter Sonnenbestrahlung solcher Platten oder Formkörper erreichen kann.A favorable working temperature occurs here, which is at a sufficient distance from the operating temperatures, which may Can reach 70 ° C in direct sunlight from such plates or moldings.

Die Kombination von Gips und Alaun hat den weiteren Vorteil, daß das im Gips gebundene Kristallwasser erst bei einer Wirktemperatur von 125 °C freigesetzt wird und sich diese mehrstufige Kristallwasserfreisetzung positiv auf den Kühlungsverlauf der Rahmenprofile auswirkt, denen die beschriebenen Platten oder sonstigen Formkörper zugeordnet werden. Darüber hinaus findet bei ca. 215 °C eine nochmalige geringe Freisetzung von im Gips gebundenem Wasser statt, die aber von untergeordneter Bedeutung ist.The combination of gypsum and alum has the further advantage that the crystal water bound in the gypsum is only released at an effective temperature of 125 ° C and this multi-stage crystal water release has a positive effect on the cooling process of the frame profiles to which the plates or other moldings described are assigned. In addition, there is again a slight release of water bound in the gypsum at approx. 215 ° C, but this is of minor importance.

Das in der Fig. 1 darstellte Metallprofil weist als Außenteile stranggepreßte Aluminiumprofile 1,2 auf, zwischen denen ein Mittelteil 3 vorgesehen ist, das in diesem Ausführungsbeispiel aus zwei parallel zueinander verlaufenden Metalleisten 4 besteht, die gegenüber den Aluminiumprofilen 1 und 2 in ihrem Wärmedurchlaß herabgesetzt sind. Die Metalleisten 4 können aus Aluminium oder aus einem anderen Metall, z.B. aus Stahl gefertigt sein. Aluminiumprofile 1 und 2 weisen Innenkammern 5,6 auf, in die die Innenkammer vollständig oder teilweise ausfüllende Formkörper aus einem wärmebindenden, hydrophilen Adsorbens eingeführt werden können. Die Aluminiumprofile 1 und 2 weisen Verankerungsnuten 7,8 für die Fußstege 11 der Metalleisten 4 auf, die nach dem Einführen der Fußstege in die Verankerungsnuten durch Anformen der äußeren Nutstege 9 festgelegt werden. Die Metalleisten 4 begrenzen zusammen mit den Aluminiumprofilen 1 und 2 eine weitere Innenkammer 10, so daß das Verbundprofil nach der fig. 1 mit drei Innenkammern zur Aufnahme von Formkörpern mit hohem Kristallwasseranteil ausgestattet ist. Die in der Fig. 2 dargestellte Metalleiste 4 weist an den Rändern Fußstege 11 auf und ist im Bereich zwischen den Fußstegen 11 mit Ausstanzungen 12 versehen, so daß zwischen den Ausstanzungen 12, die bei dem Ausführungsbeispiel nach der Fig. 2 dreieckförmig ausgebildet sind, schmale Brückenstege 13 verbleiben.The metal profile shown in FIG. 1 has extruded aluminum profiles 1, 2 between which a central part 3 is provided, which in this exemplary embodiment consists of two metal strips 4 running parallel to one another, which reduces the heat transmission of the aluminum profiles 1 and 2 are. The metal strips 4 can be made of aluminum or another metal, for example steel. Aluminum profiles 1 and 2 have inner chambers 5, 6 into which molded articles made of a heat-binding, hydrophilic adsorbent that fill the inner chamber completely or partially can be introduced. The aluminum profiles 1 and 2 have anchoring grooves 7, 8 for the foot bars 11 of the metal strips 4, which are fixed after the insertion of the foot bars into the anchoring grooves by molding the outer groove bars 9. The metal strips 4 limit together with the aluminum profiles 1 and 2 a further inner chamber 10, so that the composite profile according to the fig. 1 is equipped with three inner chambers for receiving shaped bodies with a high proportion of water of crystallization. The metal strip 4 shown in FIG. 2 has foot ridges 11 at the edges and is provided with cutouts 12 in the area between the foot ridges 11, so that between the cutouts 12, which are triangular in the embodiment according to FIG. 2, narrow Bridge webs 13 remain.

Auf diese Brückenstege reduziert sich im Brandfall die Wärmeleitung von dem außenliegenden Aluminiumprofil zu dem an der brandabgewandten Seite vorgesehenen Aluminiumprofil.In the event of a fire, the heat conduction from the external aluminum profile to the aluminum profile provided on the side facing away from the fire is reduced to these bridges.

In der Fig. 3 ist eine Metalleiste 4 dargestellt, die mit rechteckförmigen Ausstanzungen 14 versehen ist, zwischen denen nur Brückenstege 15 für die Wärmeleitung verbleiben.In Fig. 3, a metal strip 4 is shown, which is provided with rectangular perforations 14, between which only bridge webs 15 remain for heat conduction.

Die Ausstanzungen können eine beliebige geometrische Form haben.The cut-outs can have any geometric shape.

Die Breite b des Brückenstegs und seine Dicke d können variiert werden, um den Wärmefluß herab- oder heraufzusetzen.The width b of the bridge web and its thickness d can be varied in order to reduce or increase the heat flow.

Als besonders vorteilhaft, insbesondere in statischer und festigkeitsmäßiger Hinsicht haben sich dreieckförmige Ausstanzungen entsprechend der Fig. 2 ergeben, die wechselweise gegeneinander versetzt sind und ein gleichwinkliges Dreieck bilden.Triangular punchings according to FIG. 2, which are mutually offset and form an equiangular triangle, have been found to be particularly advantageous, particularly in terms of statics and strength.

In der Fig. 4 sind Türrahmenprofile im Schnitt dargestellt.In Fig. 4 door frame profiles are shown in section.

Der Blendrahmen 16 wurde aus einem Profil gefertigt, wie es in der Fig. 1 aufgezeigt ist. Das Blendrahmenprofil setzt sich aus Aluminiumprofilen 1 und 2 zusammen, die durch Metalleisten 4 miteinander verbunden sind, wobei die Metalleisten Ausstanzungen 12 bzw. 14 aufweisen, so daß der Wärmefluß durch diese das Mittelteil des Verbundprofils bildenden Metalleisten 4 herabgesetzt ist.The frame 16 was made from a profile, as shown in FIG. 1. The frame profile is composed of aluminum profiles 1 and 2, which are connected to one another by metal strips 4, the metal strips having cutouts 12 and 14, respectively, so that the heat flow through these metal strips 4 forming the central part of the composite profile is reduced.

Der Flügelrahmen 17 besteht aus die Außenteile bildenden Profilschalen 18,19, die aus Aluminium gefertigt sind und durch Metalleisten 4, die eine Wärmedämmung bilden, verbunden sind. Vervollständigt wird der Flügelrahmen durch eine Glashalteleiste 20, die eine Innenkammer 21 zur Aufnahme eines aus Alaun und Gips bestehenden Formkörpers 22 aufweist. In den Innenkammern 5 und 6 des Blendrahmens 16 sowie in den Innenkammern 23 und 24 des Flügelrahmens 17 sind ebenfalls Formkörper 25,26,27 und 28 aus Alaun und Gips mit einem hohen Kristallwasseranteil angeordnet.The sash 17 consists of the outer parts forming profile shells 18, 19, which are made of aluminum and are connected by metal strips 4, which form thermal insulation. The casement is completed by a glass retaining strip 20, which has an inner chamber 21 for receiving a molded body 22 consisting of alum and plaster. Shaped bodies 25, 26, 27 and 28 made of alum and gypsum with a high proportion of water of crystallization are also arranged in the inner chambers 5 and 6 of the frame 16 and in the inner chambers 23 and 24 of the casement 17.

Die Formkörper können auch aus anderen Komponenten sich zusammensetzen, von denen mindestens eine einen hohen Kristallwasseranteil aufweist, der bei einer Temperatur freigesetzt wird, die unterhalb der Schmelztemperatur des dem Brand zugewandten Leichtmetallprofils liegt. Das freigesetzte Kristallwasser dient zur Kühlung der Metallprofile.The moldings can also be composed of other components, at least one of which has a high proportion of water of crystallization which is released at a temperature which is below the melting temperature of the light metal profile facing the fire. The crystal water released serves to cool the metal profiles.

Die plattenförmigen Formkörper 25,26,27,28, die die jeweilige Innenkammer nur teilweise ausfüllen, werden mit Metallfedern 29 in die Innekammern eingeschoben, wobei sich die Metallfedern 29 an den plattenförmigen Formkörpern mit ihren freien Enden verkrallen und so in ihrer Lage gesichert werden.The plate-shaped bodies 25, 26, 27, 28, which only partially fill the respective inner chamber, are inserted into the inner chambers with metal springs 29, the metal springs 29 clawing at the plate-shaped bodies with their free ends and thus being secured in their position.

Die energieverzehrenden Formkörper können auch Formteile beliebiger Länge sein, die der Innenkontur der Innenkammer der Metallprofile angepaßt sind.The energy-consuming shaped bodies can also be shaped parts of any length, which are adapted to the inner contour of the inner chamber of the metal profiles.

Das energieverzehrende Material kann auch in flüssiger Form in die Innenkammer eines Metallprofils eingefüllt werden und bindet dann in der Innenkammer zu einem festen Formkörper ab.The energy-consuming material can also be poured into the inner chamber of a metal profile in liquid form and then sets in the inner chamber to form a solid molded body.

Da Türen sehr häufig oberflächenbehandelt werden, muß das Befüllen der Innenkammern mit einem energieverzehrenden Formkörper mit hohem Kristallwasseranteil nach der Oberflächenbehandlung der Profile erfolgen, da die Trocknungstemperaturen der Pulverbeschichtung in einem Temperaturbereich liegen, der der Ansprechtemperatur des energieverzehrenden Materials entspricht.Since doors are very often surface-treated, the inner chambers must be filled with an energy-consuming molded body with a high proportion of water of crystallization after the surface treatment of the profiles, since the drying temperatures of the powder coating are in a temperature range that corresponds to the response temperature of the energy-consuming material.

In der Fig. 4 ist im Beschlagfalz zwischen Blend- und Flügelrahmen jeweils vor der Metalleiste 4 eine Nut 30 vorgesehen, in der ein Brandschutzstreifen 31 aus unter Temperatur aufblähendem Material vorgesehen ist. Der Brandschutzstreifen 31 hat zum einen die Aufgabe, die gelochte Metalleiste 4 vom sichtbaren Falz her abzudecken und andererseits im Brandfall dafür zu sorgen, daß der Falzraum weitgehendst durch aufblähendes Material geschlossen wird, um ein Durchtreten von Brandgasen zu verhindern.In FIG. 4, a groove 30 is provided in the fitting rebate between the frame and sash frame in front of the metal strip 4, in which a fire protection strip 31 made of material that expands under temperature is provided. The fire protection strip 31 has, on the one hand, the task of covering the perforated metal strip 4 from the visible fold and, on the other hand, in the event of a fire, to ensure that the rebate space is largely closed by inflating material in order to prevent the passage of fire gases.

In der Regel sind lediglich die Innenkammern der Blend- und Flügelrahmen an den Außenseiten mit energieverzehrendem Material ausgefüllt. In besonderen Fällen, in denen es um die Erhöhung der Temperaturbeständigkeit über die Widerstandszeit geht, kann auch die Innenkammer des Mittelteils des jeweiligen Verbundprofils mit energieverzehrendem Material ausgefüllt werden.As a rule, only the inner chambers of the frame and sash on the outside are filled with energy-consuming material. In special cases in which the temperature resistance is increased over the resistance time, the inner chamber of the central part of the respective composite profile can also be filled with energy-consuming material.

Durch die das Mittelteil bildenden, gelochten Metalleisten 4 wird aufgrund der Lochung der Wärmefluß herabgesetzt, da durch die Lochungen die Wärmeübergangsquerschnitte verringert wurden. Eine völlige Wärmedämmung, wie sie bei den bekannten Brandscbutzkonstruktionen üblich sind und wie sich auch im Fenster- und Türenbau zum Zwecke des allgemeinen Wärmeschutzes eingesetzt wird, ist hier nicht gewünscht und beabsichtigt. Im Bereich des Mittelteils der Metallprofile ist ein Wärmefluß notwendig, da nicht nur die der Brandseite zugewandte, energieverzehrenden Formkörper zum Freisetzen des Kristallwassers aktiviert werden müssen, sondern auch die an der brandabgewandten Seite angeordneten energieverzehrenden Formkörper. Hierdurch ist es möglich, bei kleiner Bauweise der Metallprofile genügend gebundenes Wasser zur Verfügung zu haben, um die Anforderungen an eine Brandschutzkonstruktion hinsichtlich der Oberflächentemperaturen und der Standdauer der dem Brand ausgesetzten Profile zu erreichen.Through the perforated metal strips 4 forming the middle part, the heat flow is reduced due to the perforation, since the heat transfer cross sections have been reduced through the perforations. Complete thermal insulation, as is customary in the known fire plaster constructions and as is also used in window and door construction for the purpose of general heat protection, is not desired and intended here. A heat flow is necessary in the area of the central part of the metal profiles, since not only the energy-consuming shaped bodies facing the fire side have to be activated to release the crystal water, but also the energy-consuming moldings arranged on the side facing away from the fire. This makes it possible to have sufficient bound water available with a small construction of the metal profiles in order to meet the requirements for a fire protection construction with regard to the surface temperatures and the service life of the profiles exposed to the fire.

Die Metalleiste 4 aus einem Strangpreßprofil, in das Durchbrüche eingestanzt werden bzw. aus gewalztem Stahl bietet den großen Vorteil, daß sie separat bearbeitet und mit bekannten Verbundverfahren mit den übrigen, Hohlkammerprofilen zusammengefügt werden kann.The metal strip 4 from an extruded profile, into which openings are punched or from rolled steel offers the great advantage that it can be processed separately and joined together with the other hollow chamber profiles using known composite methods.

Die energieverzehrenden Formkörper sind so eingestellt, daß sie eine Ansprechtemperatur im Bereich von 80 °C bis 150 °C haben.The energy-consuming moldings are set so that they have a response temperature in the range from 80 ° C to 150 ° C.

In den Fällen, in denen die brandzugewandte Seite bereits bei der Baukonzeption bekannt ist, kann die Befüllung der jeweiligen Innenkammern der Metallprofile unterschiedlich erfolgen. Auf der dem Brand zugewandten Seite kann ein höherer Füllungsgrad als auf der dem Brand abgewandten Seite vorgenommen werden bzw. können die Ansprechtemperaturen auf der brandzugewandten Seite höher gewählt werden als auf der brandabgewandten Seite. Dies kann durch Variieren der energieverzehrenden Werkstoffe erreicht werden.In the cases where the side facing the fire is already known in the construction concept, the respective inner chambers of the metal profiles can be filled differently. On the side facing the fire, a higher degree of filling than on the side facing away from the fire can be carried out or the response temperatures on the side facing the fire can be selected higher than on the side facing away from the fire. This can be achieved by varying the energy-consuming materials.

Aus der Fig. 5 ergibt sich, daß anstelle der Metalleiste 4 im Mittelteil 3 des Profils auch eine mehrteilige Isolierleiste 32 eingesetzt werden kann. Diese mehrteilige Isolierleiste 32 besteht aus einer extrudierten, schlecht wärmeleitenden Kunststoffleiste 33, die sich über die gesamte Länge der Isolierleiste erstreckt und an seinen Längskanten Fußprofilierungen 34 aufweist. Diese Fußprofilierungen 34 werden vorzugsweise in gleichen Abständen ausgespart und es werden in diese Aussparungen zu den Fußprofilierungen 34 konturengerechte Fußprofilierungen 35 eines Brückensteges 36 aus Metall, vorzugsweise aus Aluminium eingesetzt. Die Fußprofilierungen werden in den Aufnahmenuten der Aluminiumprofile 1 und 2 verankert. Die metallischen Brückenstege haben die Aufgabe, einen Wärmefluß zwischen den Aluminiumprofilen 1 und 2 sicherzustellen. Die Breite der Brückenstege und die Abstände zueinander können variiert werden, so daß man hierdurch den Energiefluß zwischen den Aluminiumprofilen 1 und 2 beeinflussen kann.From Fig. 5 it follows that a multi-part insulating strip 32 can be used instead of the metal strip 4 in the central part 3 of the profile. This multi-part insulating strip 32 consists of an extruded, poorly heat-conducting plastic strip 33, which extends over the entire length of the insulating strip and has foot profiles 34 on its longitudinal edges. These foot profiles 34 are preferably cut out at equal intervals, and contoured foot profiles 35 of a bridge web 36 made of metal, preferably of aluminum, are inserted into these recesses in relation to the foot profiles 34. The foot profiles are anchored in the grooves of aluminum profiles 1 and 2. The metallic bridges have the task of ensuring a heat flow between the aluminum profiles 1 and 2. The width of the bridge webs and the distances from one another can be varied so that the energy flow between the aluminum profiles 1 and 2 can thereby be influenced.

Eine weitere Ausführungsform des als Wärmedämmzone ausgebildeten Mittelteils 3 zwischen den Aluminiumprofilen 1 und 2 ist in der Fig. 6 dargestellt, in der die gelochten Metalleisten 37,38 einstückig mit dem Aluminiumprofil 1 bzw. mit dem Aluminium 2 sind. Die am Aluminiumprofil 1 angeordnete Metalleiste 37 greift mit einem Fußsteg 39 in die zugeordnete Verankerungsnut des Aluminiumprofils 2, während die mit dem Aluminiumprofil 2 einstückige Metalleiste 38 mit ihrem Fußsteg 40 in die Verankerungsnut des Aluminiumprofils 1 greift. Die Metalleisten 37,38 sind entsprechend den Darstellungen 2 und 3 ausgestanzt und bilden ein dort aufgezeigtes Gitterwerk, durch das der Wärmefluß zwischen den Aluminiumprofilen 1 und 2 herabgesetzt wird.A further embodiment of the middle part 3, which is designed as a thermal insulation zone, between the aluminum profiles 1 and 2 is shown in FIG. 6, in which the perforated metal strips 37, 38 are made in one piece with the aluminum profile 1 or with the Aluminum 2 are. The metal bar 37 arranged on the aluminum profile 1 engages with a foot bridge 39 in the associated anchoring groove of the aluminum profile 2, while the metal bar 38 which is integral with the aluminum profile 2 engages with its foot bridge 40 in the anchoring groove of the aluminum profile 1. The metal strips 37, 38 are punched out according to the representations 2 and 3 and form a latticework shown there, by means of which the heat flow between the aluminum profiles 1 and 2 is reduced.

Die Fig. 7 und 8 zeigen konstruktive Einzelheiten zu der Ausführung nach der Fig. 4.7 and 8 show structural details of the embodiment according to FIG. 4th

In der Fig. 9 ist ein Schaubild in Hinsicht auf einen energieverzehrenden Formkörper dargestellt, der sich aus Kalium-Alaun und Gips zusammensetzt.FIG. 9 shows a diagram with regard to an energy-consuming shaped body which is composed of potassium alum and gypsum.

Die Kurve 1 zeigt die Ansprechtemperaturen des Formkörpers aufgetragen über die untere Temperaturachse. Aus dieser Kurve sind die Ansprechtemperaturen zu erkennen, bei denen Kristallwasser freigesetzt wird. Die Fläche unter der Kurve 1 stellt den Gesamtenergieverzehr dar.Curve 1 shows the response temperatures of the molded body plotted over the lower temperature axis. The response temperatures at which crystal water is released can be seen from this curve. The area under curve 1 represents total energy consumption.

Die Kurve zeigt lediglich den Masseverlust, der sich im Verlauf der Temperaturerhöhung einstellt.The curve only shows the mass loss that occurs as the temperature rises.

In der Fig. 10 ist ein Metallprofil aufgezeigt, das sich, wie das Profil nach der Fig. 1 aus den Aluminiumprofilen 1 und 2 sowie im Mittelteil aus den gelochten Metalleisten 4 zusammensetzt. Die Innenkammern 5,6 und 10 sind mit energieverzehrenden und Kristallwasser freisetzenden Formkörpern 41,42,43 ausgefüllt, die z.B. aus Alaun und Gips bestehen können.10 shows a metal profile which, like the profile according to FIG. 1, is composed of the aluminum profiles 1 and 2 and, in the middle part, of the perforated metal strips 4. The inner chambers 5, 6 and 10 are filled with energy-consuming and crystal water-releasing shaped bodies 41, 42, 43 which e.g. can consist of alum and plaster.

Bei dem Ausführungsbeispiel nach der Fig. 10 ist zusätzlich ein plattenförmiger Formkörper 44 an der Außenseite des Aluminiumprofils 1 befestigt, so daß im Fall eines Brandes in der Nähe des Formkörpers 44 dieser zunächst aktiviert wird und Kristallwasser freisetzt. Bei längerer Branddauer werden auch die Formkörper 41,42 und 43 aktiviert und setzen Kristallwasser frei, so daß hierdurch eine intensive Kühlung der Aluminiumprofile und damit eine lange Standzeit der Gesamtkonstruktion erreicht wird.In the embodiment according to FIG. 10, a plate-shaped molded body 44 is additionally fastened to the outside of the aluminum profile 1, so that in the event of a fire in the vicinity of the molded body 44, this is first activated and crystal water is released. In the event of a longer fire, the moldings 41, 42 and 43 are also activated and release crystal water, so that intensive cooling of the aluminum profiles and thus a long service life of the overall construction is achieved.

In der Fig. 11 ist eine Fassaden- oder eine Dachkonstruktion aufgezeigt, bei der die Fassadenfelder bzw. die Rahmenfelder des Daches mit Glasscheiben 45 ausgefüllt sind. An der Rauminnenseite ist ein Hauptprofil 46 aus Aluminium vorgesehen. Dieses Hauptprofil wird durch plattenförmige, energieverzehrende Formkörper 47,48 und 49 abgedeckt, die bei dem Erreichen einer Ansprechtemperatur Kristallwasser freisetzen und hierdurch das Hauptprofil kühlen.11 shows a facade or a roof structure in which the facade fields or the frame fields of the roof are filled with glass panes 45. A main profile 46 made of aluminum is provided on the inside of the room. This main profile is formed by plate-shaped, energy-consuming shaped bodies 47, 48 and 49 covered, which release crystal water when a response temperature is reached and thereby cool the main profile.
