Description

Ein gattungsgemäßes Verbundprofil nach Art eines Rahmenwerkes aus Metallprofilen in Brandschutzausführung ist aus der EP 0 717 165 B1 bekannt. Das gattungsgemäße Rahmenwerk besteht aus einem Leichtmetall wie Aluminium und weist zwei Metallprofile auf, die durch ein Mittelprofil (Isoliersteg) miteinander verbunden sind. Dabei bilden die Metallprofile Kammern aus, in welche Brandschutzleisten oder Brandschutzformkörper aus einem wärmebindenden, hydrophilen Adsorbens mit hohem Kristallwasseranteil einsetzbar sind. Das in den verwendeten Brandschutzleisten oder Brandschutzformkörpern vorhandene Kristallwasser wird je nach Zusammensetzung der Brandschutzleisten oder Brandschutzformkörper im Brandfall bei einer Temperatureinwirkung von 73 bis 215 °C freigesetzt. Die Kammern der Aluminiumprofile sind geschlossen ausgebildet, so daß die in die Kammern einsetzbaren Brandschutzleisten oder Brandschutzformkörper aus dem hydrophilen Adsorbens nicht aus den Metallprofilen ausfallen können.A generic composite profile in the manner of a framework made of metal profiles in fire protection design is known from EP 0 717 165 B1. The generic Framework is made of a light metal such as aluminum and has two metal profiles that are connected to each other by a central profile (insulating bridge) are. The metal profiles form chambers in which fire protection strips or fire protection molded body made of a heat-binding, hydrophilic adsorbent with a high crystal water content can be used. That used in the Fire protection strips or fire protection moldings existing crystal water depending on the composition of the fire protection strips or fire protection moldings in Fire released at a temperature of 73 to 215 ° C. The chambers the aluminum profiles are closed, so that the in the chambers usable fire protection strips or fire protection moldings from the hydrophilic Adsorbent cannot fall out of the metal profiles.

Die Isolierstege bestehen in der Regel aus Kunststoff, um eine gute Wänneisolierung zwischen den beiden Metallprofilen zu erzielen. Parallel zum Isoliersteg bzw. am Isoliersteg (KS-Isoliersteg) sind metallische Verankerungselemente ausgebildet, die aus Metalleisten bestehen, die mit Aussparungen bzw. Ausstanzungen versehen sind, um den Wärmefluß zwischen den beiden Metallprofilen möglichst gering zu halten. Die Verankerungselemente sollen einerseits stabil genug ausgelegt sein, um Haltekräfte zwischen den beiden Metallprofilen erzeugen zu können, sie sollen aber andererseits möglichst geringe Dimensionen aufweisen, um den Wärmefluß zwischen den beiden Metallprofilen nicht unnötig zu erhöhen.The insulating bars are usually made of plastic to ensure good insulation to achieve between the two metal profiles. Parallel to the insulating web or metallic anchoring elements are formed on the insulating web (KS insulating web), which consist of metal strips, which are provided with cutouts or cutouts are in order to minimize the heat flow between the two metal profiles hold. On the one hand, the anchoring elements should be designed to be stable enough to To be able to generate holding forces between the two metal profiles, but they should on the other hand, have dimensions that are as small as possible to keep the heat flow between not unnecessarily increase the two metal profiles.

Profile, die aus einem Verbund aus Einzelprofilen bzw. -schalen und Isolierstegen bestehen, weisen das Problem auf, daß der Verbund, der in der Regel durch Andrücken der metallischen Außenschalen an die Isolierstege hergestellt wird, sowohl in Quer- wie auch insbesondere in Längsrichtung durch das Andrücken allein nicht stabil genug ausgebildet ist. Profiles that consist of a combination of individual profiles or shells and insulating bars exist, have the problem that the composite, which is usually by pressing the metallic outer shells to the insulating bars is made, both not in the transverse as well as in the longitudinal direction by pressing alone is stable enough.

Zur Vermeidung dieser Probleme ist es bei einem bekannten Brandschutz-Stahlprofil bekannt, zur Verbesserung der Quer- und Längsschubfestigkeit den anzuformenden Nutsteg der Aufnahmenut für die Isolierleiste bzw. den Isoliersteg am Brandschutzstahlprofil in geringen Abständen einzuprägen, um derart einen Formschluß zwischen den beiden Bauteilen zu realisieren. Dieser Formschluß bzw. diese Verbindung ist zwar vorteilhaft, es ist aber nicht möglich, allein durch diese Maßnahme die in der Praxis geforderten Festigkeitswerte zu erreichen. Dies liegt u.a. daran, daß sich die Prägung nicht in die Isolierleiste hinein erstrecken kann, da diese eine hohe Druckfestigkeit aufweist und somit praktisch inkompressibel ist.To avoid these problems it is with a known fire protection steel profile known to improve the transverse and longitudinal shear strength Groove web of the receiving groove for the insulating strip or the insulating web on Emboss the fire protection steel profile at short intervals in order to achieve a positive fit between the two components. This form fit or this Connection is advantageous, but it is not possible by this measure alone to achieve the strength values required in practice. Among other things, this is the fact that the embossing cannot extend into the insulating strip, since this has a high compressive strength and is therefore practically incompressible.

Vor diesem Hintergrund zielt die Erfindung darauf ab, ein Verbundprofil der gattungsgemäßen Art, insbesondere aus Stahl, derart weiterzubilden, daß die Verbindung der Metallprofile mit dem Isoliersteg auf einfache Weise eine erhöhte Längs- und vorzugsweise auch Querschubfestigkeit aufweist.Against this background, the invention aims to provide a composite profile of the generic type Kind, in particular made of steel, such that the connection of the metal profiles with the insulating web in a simple way an increased longitudinal and preferably also has transverse shear strength.

Die Erfindung erreicht dieses Ziel durch den Gegentand des Anspruches 1.The invention achieves this aim by the subject matter of claim 1.

Danach ist der wenigstens eine Isoliersteg in seinen mit Verankerungselementen versehenen und in die wenigstens eine Aufnahmenut eingreifenden Bereichen derart mit wenigstens einem Vorsprung und/oder wenigstens einer Ausnehmung versehen, daß sich beim Anpressen oder Anrollen des Nutsteges an den wenigstens einen Isoliersteg wenigstens eine quer zur Längserstreckungsrichtung des Verbundprofils erstreckende Verformung des Nutsteges ausbildet, welche das wenigstens eine Metallprofil und den wenigstens einen Isoliersteg mit den Verankerungselementen gegen Relativverschiebungen in der Längs- und vorzugsweise auch in der Quererstreckungsrichtung des Verbundprofils sichert. Bevorzugt bildet die Verformung einen besonders gut sichernden Kantbereich aus. Der Vorsprung kann auch durch das Verankerungselement gebildet werden. After that, the at least one insulating web is in its with anchoring elements provided and engaging in the at least one receiving groove areas provided with at least one projection and / or at least one recess, that when pressing or rolling the groove web on the at least one Insulating web at least one transverse to the longitudinal direction of the composite profile extending deformation of the groove web, which forms the at least one metal profile and against the at least one insulating bridge with the anchoring elements Relative shifts in the longitudinal and preferably also in the transverse direction of the composite profile. The deformation preferably forms a particularly good securing area. The lead can also go through the anchoring element are formed.

Die Erfindung beruht somit zunächst auf dem Gedanken, beim Verbinden bzw. Anrollen des Verbundprofiles eine sich in Längsrichtung erstreckende Verformung der Befestigungsnut bzw. des die Befestigungsnut begrenzenden Nutsteges zum Ausbilden einer formschlüssigen und längsverschubresistenten Verbindung zwischen dem Isoliersteg und dem Metallprofil zu nutzen.The invention is therefore initially based on the idea of connecting or rolling on the composite profile a longitudinally extending deformation of the Fastening groove or the groove web delimiting the fastening groove for forming a positive and longitudinal shear resistant connection between to use the insulating bar and the metal profile.

Ein besonderer Vorteil der Erfindung liegt darin, daß der eigentliche Montagevorgang des Verbundprofiles, d.h. insbesondere das Zusammenrollen der einzelnen Schalen mit den Isolierstegen durch die Erfindung nicht erhöht wird. Das eigentliche Anrollen geschieht nämlich genau wie beim Stand der Technik.A particular advantage of the invention is that the actual assembly process the composite profile, i.e. especially the curling up of the individual Shells with the insulating webs is not increased by the invention. The real thing Rolling is done exactly like in the prior art.

Die Erfindung eignet sich für Verbundprofile verschiedener Art. So können die Verbundprofile aus Aluminium bestehen. Besonders bevorzugt bestehen sie allerdings aus Stahl(blech), wobei nach einer besonders bevorzugten Ausführungsform durch den Isoliersteg zwei Metallprofile miteinander verbunden werden.The invention is suitable for composite profiles of various types Composite profiles made of aluminum. However, they are particularly preferred made of steel (sheet), according to a particularly preferred embodiment two metal profiles can be connected to each other through the insulating bridge.

Nach der Erfindung sind - insbesondere zur Ausbildung eines Brandschutzprofils - vorzugsweise in die Ausnehmungen der Isolierstege Verankerungselemente eingesetzt (die aber z.B. auch direkt an die Isolierstege angesetzt werden können), welche flacher oder höher ausgebildet sind als die Ausnehmungen der Isolierstege. Dadurch, daß die Bauhöhe der Verankerungselemente geringer oder höher ist als die Erstreckung der Ausnehmungen in den Isolierstegen, wird insbesondere im Bereich der Verankerungselemente auf einfache Weise beim Anformen der Aufnahmenutstege der erfindungsgemäße Formschluß gegen Längsverschiebungen realisiert.According to the invention - in particular for forming a fire protection profile - Anchoring elements are preferably used in the recesses of the insulating webs (which, for example, can also be attached directly to the insulating bars), which ones are flatter or higher than the recesses of the insulating webs. Thereby, that the height of the anchoring elements is lower or higher than that Extension of the recesses in the insulating webs is particularly in the area the anchoring elements in a simple manner when molding the receiving groove webs the positive connection according to the invention realized against longitudinal displacements.

Hinsichtlich der Geometrie der Verankerungselemente hat sich als besonders vorteilhaft herausgestellt, die Verankerungselemente im Querschnitt mit einer C- oder U-Form zu versehen. Durch diese Form wird auch in Querrichtung ein Formschluß erreicht und somit auf einfache Weise auch die Querschubfestigkeit des Verbundprofiles gesichert. Hierin liegt insbesondere auch ein deutlicher zusätzlicher Vorteil gegenüber einer alleinigen Längsverschubsicherung allein durch Verformen der Nutstege, denn es wird auf einfachste Weise sowohl ein Längsverschub- als auch eine Querverschubsicherung realisiert und das Verbundprofil derart auf einfache Weise in (quasi) allen Richtungen umfassend gegen Relativverschiebungen seiner Einzelelemente bzw. Einzelprofile gesichert. Dies gilt insbesondere auch in dem einfach zu realisierenden Fall, daß der Nutsteg das jeweilige Verankerungselementende in seinem durchgeformten Bereich in den Nutgrund der Aufnahmenut preßt, so daß das Verankerungselement formschlüssig festgelegt und derart das Verbundprofil besonders gut in Längs- als auch in Quererstreckungsrichtung des Verbundprofils gegen Relativverschiebungen gesichert ist.With regard to the geometry of the anchoring elements, it has proven to be particularly advantageous exposed the anchoring elements in cross section with a C or U shape. This shape also creates a positive connection in the transverse direction achieved and thus also the shear resistance of the composite profile in a simple manner secured. This is also a clear additional advantage compared to securing the longitudinal displacement solely by deforming the Grooves, because it is in the simplest way both a longitudinal shift and realized a cross shift protection and the composite profile in such a simple way Comprehensively in (almost) all directions against relative shifts of its Individual elements or individual profiles secured. This is especially true in the easy to implement case that the groove web the respective anchoring element end presses the receiving groove in its formed area into the groove base, so that the anchoring element is positively fixed and so the composite profile particularly good in the longitudinal and transverse direction of the composite profile is secured against relative shifts.

Eine besonders einfache Herstellbarkeit bei hoher Stabilität der Verankerungselemente ergibt sich, wenn die Verankerungselemente metallisch ausgebildet sind und einen Formschluß zu den beiden Metallprofilen ausbilden und wenn die Verankerungselemente als Stanzbiegeteile aus Stahlblech bestehen.Particularly easy to manufacture with high stability of the anchoring elements results when the anchoring elements are metallic and form a positive connection to the two metal profiles and when the anchoring elements consist of sheet steel as stamped and bent parts.

Nach einer weiteren besonders bevorzugten Ausführungsform der Erfindung werden die Verankerungselemente zumindestens im Anrollbereich zu den Metallprofilen mit Ausnehmungen und/oder Vorsprüngen versehen, insbesondere mit Zackungen oder Wellungen, welche die Längsschubfestigkeit nochmals weiter erhöhen.According to a further particularly preferred embodiment of the invention the anchoring elements at least in the rolling area to the metal profiles provided with recesses and / or projections, in particular with serrations or corrugations that further increase the longitudinal shear strength.

In ihren an die Isolierstege angrenzenden Randbereichen können die Verankerungselemente ferner zumindestens teilweise angeschrägt ausgebildet sein, damit in diesen Randbereichen keine scharfkantigen Übergänge zu den Isolierstegen entstehen.The anchoring elements can be located in their edge regions adjacent to the insulating webs also be formed at least partially beveled, so in this There are no sharp-edged transitions to the insulating bars at the edges.

Die Verankerungselemente werden vorteilhaft mit den Isolierstegen verklebt. Alternativ ist auch ein Anklemmen an die oder Verrasten an den Isolierstege(n) denkbar, so daß die Verankerungselemente von außen nicht sichtbar sind und eine leichte Montage der Isolierstege (Einführen in die Aufnahmenuten der Profile) möglich ist. Die Isolierstege werden zum Einsetzen der Verankerungselemente in den für die Verankerungselemente bestimmten Bereichen vorzugsweise durch Ausfräsen in die gewünschte Form gebracht.The anchoring elements are advantageously glued to the insulating webs. Alternatively it is also conceivable to connect to or lock onto the insulating webs, so that the anchoring elements are not visible from the outside and a light one Installation of the insulating bars (insertion into the grooves of the profiles) is possible. The insulating bars are used to insert the anchoring elements in the Anchoring elements certain areas preferably by milling into the brought the desired shape.

Hinsichtlich der Ausbildung der Verankerungselemente ist noch anzumerken, daß die Verankerungselemente vorzugsweise derart ausgebildet werden, daß eine geringe Wärmeübertragung zwischen den Außenprofilen erfolgt. Dies wird z.B. durch eine H-Form mit einem zwei Grundstege verbindenden Quersteg gesichert, da im Bereich des Quersteges nur eine relativ geringe Wärmeübertragung möglich ist. Andererseits sind die Verankerungselemente im Bereich der Grundstege im wesentlichen formschlüssig und stabil mit den Isolierstegen verbunden.With regard to the design of the anchoring elements, it should also be noted that the anchoring elements are preferably designed such that a small Heat transfer takes place between the outer profiles. This will e.g. by an H-shape secured with a cross bar connecting two base bars, because in the Area of the crossbar only a relatively low heat transfer is possible. On the other hand, the anchoring elements are essentially in the area of the base webs positively and stably connected to the insulating bars.

Nach einem weiteren, auch unabhängig zu betrachtenden Gedanken der Erfindung (Anspruch 18) weisen die Metallprofile im Querschnitt im wesentlichen eine L-, C- oder U-Form mit einem Grundsteg und wenigstens einem winklig zum Grundsteg ausgebildeten Längssteg auf, wobei die Quer- und Längsstege wenigstens eine zumindest teilweise nach außen offene Hohlkammer ausbilden, in welche Brandschutzleisten eingesetzt sind, die durch wenigstens einen Vorsprung an den Quer- und/oder Längsstegen der Metallprofile gegen Herausfallen aus den Metallprofilen gesichert sind. Ein Verkleben, Verklemmen oder Verrasten der Brandschutzleisten und/oder -platten mit den Metallprofilen ist damit nicht erforderlich, obwohl die Hohlkammern teilweise nach außen hin offen stehen. Dies ist insbesondere bei Stahlprofilen vorteilhaft, bei denen das Ausbilden von rundum geschlossenen Hohlkammern relativ kompliziert ist. Insbesondere bei diesen Stahlprofilen ergibt sich durch das Anrollen eines Vorsprunges, vorzugsweise an die Längsstege, eine einfache Möglichkeit zur Sicherung gegen Herausfallen. According to a further idea of the invention, which can also be considered independently The cross section of the metal profiles essentially has an L, C, or U-shape with a base and at least one angle to the base trained longitudinal web, the transverse and longitudinal webs at least one at least Form partially open hollow chamber into which fire protection strips are used, which by at least one projection on the transverse and / or longitudinal webs of the metal profiles to prevent them falling out of the metal profiles are secured. Gluing, jamming or locking of the fire protection strips and / or plates with the metal profiles is not necessary, although the Some hollow chambers are open to the outside. This is particularly the case with Steel profiles advantageous, in which the formation of completely closed hollow chambers is relatively complicated. This results in particular with these steel profiles by rolling a projection, preferably on the longitudinal webs, a simple one Possibility of securing against falling out.

Die Brandschutzleisten oder -platten liegen vorzugsweise im wesentlichen formschlüssig in den Metallprofilen und werden vorzugsweise als hydrophiles Adsorbens ausgebildet. Beispiele für geeignete Stoffe sind der gattungsgemäßen EP 0 717 165 B1 zu entnehmen.The fire protection strips or panels are preferably essentially form-fitting in the metal profiles and are preferably used as a hydrophilic adsorbent educated. Examples of suitable substances are generic EP 0 717 165 B1.

Figur 1 zeigt ein erfindungsgemäßes Brandschutzstahlprofil 1, das aus einem ersten C-förmigen Außen-Metallprofil 2 und einem zweiten C-förmigen Außen-Metallprofil 3 (auch Außen- und Innenschale genannt) gebildet wird, die durch zwei zueinander parallele Isolierstege 4 miteinander verbunden sind.Figure 1 shows a fire protection steel profile 1 according to the invention, which consists of a first C-shaped outer metal profile 2 and a second C-shaped outer metal profile 3 (also called outer and inner shell) is formed by two mutually parallel insulating webs 4 are interconnected.

Sowohl das C-förmige Metallprofil 2 als auch das C-förmige Metallprofil 3 weisen jeweils einen Grundsteg 2a, 3a sowie zwei im wesentlichen senkrecht zu den Grundstegen 2a, 3a verlaufende Längsstege 2b, 3b und 2c, 3c auf, an welche wiederum nach innen hin Vorsprünge 2d, 3d und 2e, 3e angeformt sind. Brandschutzprofile 7 und 8 sind jeweils in Hohlkammern 5 und 6 der Metallprofile 2 und 3 angeordnet und liegen dort im wesentlichen formschlüssig. Die Hohlkammern 5, 6 werden im wesentlichen von den Grundstegen 2a, 3a sowie den zwei im wesentlichen senkrecht zu den Grundstegen 2a, 3a verlaufenden Längsstegen 2b, 3b und 2c, 3c begrenzt, wobei die Vorsprünge 2d, 3d und 2e, 3e die Brandschutzleisten 7, 8 gegen Herausfallen aus den Hohlkammern 7, 8 sichern. Die nach innen weisenden Vorsprünge 3d und 3e an den Längsstegen 3b und 3c bilden wiederum Isolierstegaufnahmenuten 9 aus, die zur Aufnahme der Isolierstegfüße 10 dienen.Both the C-shaped metal profile 2 and the C-shaped metal profile 3 have one base web 2a, 3a and two substantially perpendicular to each Basic webs 2a, 3a extending longitudinal webs 2b, 3b and 2c, 3c, on which in turn Projections 2d, 3d and 2e, 3e are formed on the inside. Fire protection profiles 7 and 8 are each arranged in hollow chambers 5 and 6 of the metal profiles 2 and 3 and lie there essentially form-fitting. The hollow chambers 5, 6 are essentially of the base webs 2a, 3a and the two essentially longitudinal webs 2b, 3b and 2c running perpendicular to the base webs 2a, 3a, 3c limits, the projections 2d, 3d and 2e, 3e the fire protection strips 7, 8 Secure against falling out of the hollow chambers 7, 8. Those facing inwards Projections 3d and 3e on the longitudinal webs 3b and 3c in turn form insulating web receiving grooves 9, which serve to receive the insulating web feet 10.

Die Metallprofile 2, 3 bestehen aus einem Stahlblech, welches nach Art der Figur 1 in die gewünschte Profilform umgebogen bzw. rollgeformt ist, d.h., sowohl die Längsstege als auch die Querstege werden direkt aus einem Blech hergestellt. Analoges gilt für die Isoliersteg-Aufnahmenuten 9, welche aus den Randbereichen des Bleches geformt sind. Die Isolierstegfüße 10 liegen seitlich nach innen versetzt unterhalb der Isolierstegoberfläche 13.The metal profiles 2, 3 consist of a steel sheet, which in the manner of FIG. 1 is bent or roll-formed into the desired profile shape, i.e. both Longitudinal bars as well as the transverse bars are made directly from a sheet. Analogue applies to the insulating web receiving grooves 9, which from the edge areas of the Sheets are formed. The insulating web feet 10 are laterally offset inwards below the insulating web surface 13.

Die Isolierstegfüße 10 sind formschlüssig in die Aufnahmenuten 9 eingesetzt. Dies erfolgt dadurch, daß bei dem Verbinden der Metallprofile mit den Isolierstegen des Hohlprofils die Nutstege 11 in den äußeren Bereichen 12 plastisch verformt werden, d.h., die Nutstege 11 werden mit den Bereichen 12 an die Isolierstege herangedrückt bzw. herangerollt. Auf diese Weise entsteht eine kraft- und formschlüssige Verbindung zwischen den Metallprofilen und den Isolierstegen. The insulating web feet 10 are positively inserted into the receiving grooves 9. This is done in that when connecting the metal profiles with the insulating webs The groove webs 11 are plastically deformed in the outer regions 12, i.e. the groove webs 11 are pressed against the insulating webs with the areas 12 or rolled up. In this way, a non-positive and positive fit is created Connection between the metal profiles and the insulating bars.

Die Isolierstegoberfläche 13 kann eine bündige Oberfläche mit Teilbereichen der Innen- und Außenmetallprofile 2, 3 ausbilden oder die Metallprofile sind derart ausgebildet, daß oberhalb des Isolierstegs eine offene Hohlkammer 14 entsteht. Diese Hohlkammer dient z.B. zur Aufnahme von aufschäumenden Brandschutzbändern oder zur Aufnahme von Befestigungsmitteln wie Nutsteinen für Beschlagteile (hier nicht dargestellt). In Fig. 1 oberhalb der Hohlkammer 14 ist eine Beschlagsebene 15 ausgebildet, auf der z.B. Stulpschienen für Schlösser aufliegen können.The insulating web surface 13 can be a flush surface with partial areas of the Form inner and outer metal profiles 2, 3 or the metal profiles are such formed that an open hollow chamber 14 is formed above the insulating web. This hollow chamber serves e.g. to accommodate foaming fire protection tapes or to hold fasteners such as slot nuts for fittings (not shown here). In Fig. 1 above the hollow chamber 14 is a fitting level 15, on which e.g. Fit the faceplate for locks can.

Durch das Anrollen der Nutstege 11 wird eine formschlüssige Verbindung mit einem Hinterschnitt in den Anrollbereichen 12 der Profile und der Isolierstegfüße 10 in der Querschubrichtung X erreicht. In dieser Richtung ist das Verbundprofil 1 damit gegen Relativverschiebungen seiner Elemente gesichert.By rolling the groove webs 11 a positive connection with a Undercut in the rolling areas 12 of the profiles and the insulating web feet 10 reached in the transverse thrust direction X. The composite profile is 1 in this direction thus secured against relative displacements of its elements.

In der Längsschubrichtung - hier senkrecht zur Schnittebene verlaufend - wird dagegen durch die Erfindung die kraftschlüssige Verbindung zwischen den Metallprofilen und den Isolierstegen deutlich verbessert. Dies wird nachfolgend näher erläutert.In the longitudinal thrust direction - here perpendicular to the cutting plane - is opposed by the invention the non-positive connection between the metal profiles and significantly improved the insulating bars. This is explained in more detail below.

Figur 2 zeigt - wie Fig. 1 - das erfindungsgemäße Brandschutz-Verbundprofil 1 im Schnitt, jedoch ergänzt um Verankerungselemente 16, die unterhalb der Isolierstege 4, d.h. zum Profilinneren hin angeordnet sind. Die Verankerungselemente 16 sind somit von außen nicht sichtbar. Der Querschnitt der Verankerungselemente 16 überlappt sich im Nutbereich 9 mit dem Querschnitt der Isolierstege. Der Querschnitt der Verankerungselemente 16 ist kleiner als der Querschnitt der Isolierstegfüße 10. Die Verankerungselemente 16 werden abschnittsweise in seitliche Aussparungen 20 (siehe hierzu auch Fig. 4) der Isolierstege 4 eingesetzt und vorteilhaft an der Unterseite 17 der Isolierstege verklebt oder verrastet. FIG. 2 shows - like FIG. 1 - the fire protection composite profile 1 according to the invention Section, but supplemented by anchoring elements 16, which are below the insulating webs 4, i.e. are arranged towards the inside of the profile. The anchoring elements 16 are therefore not visible from the outside. The cross section of the anchoring elements 16 overlaps in the groove area 9 with the cross section of the insulating webs. The cross section the anchoring elements 16 is smaller than the cross section of the insulating web feet 10. The anchoring elements 16 are cut in sections into lateral recesses 20 (see also Fig. 4) of the insulating webs 4 used and advantageous the underside 17 of the insulating webs glued or locked.

Die Verankerungselemente 16 weisen im Querschnitt der Fig. 2 und 3 im wesentlichen eine C-Form auf (s. hierzu Fig. 5). In Fig. 4 wird zudem deutlich, daß die Verankerungselemente in einer hierzu senkrechten Ebene ferner H-förmig ausgebildet sind.The anchoring elements 16 essentially have a cross section in FIGS. 2 and 3 a C-shape (see Fig. 5). In Fig. 4 it is also clear that the anchoring elements H-shaped in a plane perpendicular thereto are.

Beim Anrollen der Nutstege 11 werden diese bis auf die Oberfläche 19 der Verankerungselemente 16 herabgedrückt (siehe hierzu Fig. 3). Der hierdurch entstehende Höhenunterschied H bewirkt den erfindungsgemäßen Formschluß zwischen den Metallprofilen 2, 3 und dem Isoliersteg 4 in der Längsschubrichtung. Die C- oder U-förmigen Enden 18 der Verankerungselemente verbessern den Formschluß in der Querschubrichtung X.When the groove webs 11 roll on, they become up to the surface 19 of the anchoring elements 16 depressed (see Fig. 3). The resulting Height difference H causes the positive connection between the Metal profiles 2, 3 and the insulating web 4 in the longitudinal direction. The C or U-shaped ends 18 of the anchoring elements improve the positive connection in the Cross direction X.

Figur 4 zeigt das Brandschutz-Stahlprofil in einer perspektivischen Ansicht. Wie gut zu erkennen, ist das Verankerungselement 16 in seinem an den Nutsteg 11 angerollten Zustand dargestellt. Die U-förmigen Enden 18 der Verankerungselemente 16 liegen in den Aussparungen 20 der Isolierstege 4.Figure 4 shows the fire protection steel profile in a perspective view. How The anchoring element 16 is clearly visible in its on the groove web 11 rolled state shown. The U-shaped ends 18 of the anchoring elements 16 lie in the cutouts 20 of the insulating webs 4.

Die Profilstege 11 der Aufnahmenuten 9 werden erfindungsgemäß vorteilhaft im Bereich 21 der Verankerungselemente abgesenkt. Insbesondere die sich hierdurch ausbildenden Kantbereiche 22 in den Profilstegen 11 bewirken die erfindungsgemäße formschlüssige Verbindung in der Längsschubrichtung Y.The profile webs 11 of the receiving grooves 9 are advantageous in the invention Lowered area 21 of the anchoring elements. In particular, this is Forming edge regions 22 in the profile webs 11 effect the invention positive connection in the longitudinal direction of Y.

Wie in Figur 5 und Figur 6 zu erkennen, weist das H-förmige Verankerungselement 16 einen Quersteg 23 mit einem relativ geringen Querschnitt auf, so daß die Wärmeleitfähigkeit des Bereich des Quersteges 23 relativ niedrig ist. Ausstanzungen 24 rechts und links zum mittleren Quersteg 23 (hier im wesentlichen rechteckig) können beliebig ausgestaltet werden und auch andere Formen, wie z.B. eine dreieckige Form oder eine Halbkreisform aufweisen. As can be seen in FIG. 5 and FIG. 6, the H-shaped anchoring element has 16 a crossbar 23 with a relatively small cross-section, so that the thermal conductivity the area of the crosspiece 23 is relatively low. Die cuts 24 right and left to the central cross piece 23 (here essentially rectangular) can be designed in any way and also other shapes, e.g. a triangular one Have shape or a semi-circular shape.

Figur 7 veranschaulicht, daß der Isoliersteg 4 und das Verankerungselement 16 vorzugsweise zum Bilden einer vormontierten Einheit einfach durch Verkleben (oder alternativ - hier nicht dargestellt - durch Verrasten) der beiden Bauteile miteinander verbunden werden. Das Verkleben oder Verrasten der beiden Bauteile im Bereich der Klebefläche 25 wird vorteilhaft vor der eigentlichen Montage des Verbundprofils werkseitig vorgenommen. Der Isoliersteg 4 und seine Verankerungselemente 16 bilden derart die vormontierte Baueinheit, welche lediglich noch durch ein einfaches Anrollen nach Art herkömmlich ausgestalteter Isolierstege mit den Metallprofilen verbunden werden muß. Die Verankerungselemente 16 können je nach Auslegung beliebig oft am Isoliersteg 4 angeordnet werden.Figure 7 illustrates that the insulating web 4 and the anchoring element 16 are preferred to form a pre-assembled unit simply by gluing (or alternatively - not shown here - by locking) the two components together get connected. The gluing or locking of the two components in the area the adhesive surface 25 is advantageous before the actual assembly of the composite profile made at the factory. The insulating web 4 and its anchoring elements 16 thus form the pre-assembled unit, which is only a simple Rolling in the manner of conventionally designed insulating bars with the metal profiles must be connected. The anchoring elements 16 can, depending on the design can be arranged as often as required on the insulating web 4.

Figur 9 veranschaulicht, daß die Enden 18 des Verankerungselementes 16 gezackt ausgebildet sein können (s. Zacken 26). Die gezackte Form in Längsrichtung erhöht nochmals den Widerstand gegen Längsverschiebungen des Profils. Ebenso tragen Ein- und Auslaufschrägen 27 an den Enden bei einer entsprechenden Dimensionierung u.U. auch zur Erhöhung der Längsschubfestigkeit bei. Die Zacken und/oder Schrägen 26, 27 können je nach der gewünschten Auslegung beliebig häufig ausgebildet werden.Figure 9 illustrates that the ends 18 of the anchoring element 16 are serrated can be formed (see serrations 26). The jagged shape increases lengthways again the resistance to longitudinal displacements of the profile. Wear as well Inlet and outlet bevels 27 at the ends with appropriate dimensions possibly also to increase the longitudinal shear strength. The prongs and / or Depending on the desired design, bevels 26, 27 can be formed as often as desired become.

Die Ein- und Auslaufschrägen 27 verhindern insbesondere auch in unkomplizierter Weise ein Verhaken der Verankerungselemente 16 an den Profilen beim Einführen der Isolierstege in die Profile. The inlet and outlet bevels 27 prevent in particular in a more uncomplicated manner Way a hooking of the anchoring elements 16 on the profiles when inserting the insulating bars in the profiles.
