Description

Die Erfindung betrifft ein Bauelement zur Wärmedämmung zwischen einem Gebäude und einem vorkragenden Außenteil, bestehend aus einem dazwischen zu verlegenden Isolierkörper mit integrierten metallischen Bewehrungsstäben, die sich quer zum Isolierkörper durch diesen hindurch erstrecken und beidseits vorstehen, wobei der Isolierkörper zumindest eine mit ihm fest verbundene Leiste aufweist, die aus einem härteren Material als der Isolierkörper besteht und an ihren den zu betonierenden Bauteilen zugewandten Seiten Ausnehmungen aufweist, in denen Bewehrungsstäbe fixiert sind.The invention relates to a component for thermal insulation between a building and a cantilevered outer part, consisting of one to be installed in between Insulating body with integrated metallic reinforcing bars, which cross through the insulating body extend through and protrude on both sides, the Insulating body at least one firmly connected to it Has a bar made of a harder material than the insulating body is there and on their to be concreted Has recesses on the side facing the components, in which reinforcement bars are fixed.

Derartige Bauelemente gestatten es, vorkragende Betonteile, insbesondere Balkonplatten, mit der entsprechenden Zwischendecke eines Gebäudes zu verbinden, wobei die sonst üblichen Wärmebrücken weitestgehend eliminiert werden. Derartige Bauelemente setzten sich daher in der Praxis immer stärker durch und sind inzwischen in zahlreichen Ausführungsformen bekannt. Im allgemeinen ist jeder Isolierkörper mit mehreren horizontal durchlaufenden Zug- und Druckstäben und gegebenenfalls noch mit Querkraftstäben bestückt, wobei die Anzahl der Bewehrungsstäbe von der Länge des Isolierkörpers und von den zwischen den anschließenden Betonbauteilen zu übertragenden Kräften abhängig ist. Dabei stehen insbesondere die Zugstäbe relativ weit aus dem Isolierkörper vor, damit eine ausreichende Überdeckung mit der Anschlußbewehrung der beidseits zu betonierenden Bauteile gewährleistet ist. An ihren Enden sind die Zugstäbe meist mit einem gemeinsamen Querstab verbunden, um ihre Position relativ zueinander und relativ zum Isolierkörper zu fixieren. Diese Lagefixierung kann durch Leisten übernommen werden, die fest mit dem Isolierkörper verbunden sind und aus einem härteren Material als dieser bestehen. Während der Isolierkörper aus einem Material wie Polystyrol oder einem ähnlichen schaumartigen Kunststoff besteht, bestehen die Leisten beispielsweise aus einem Vollkunststoff, Holz, Faserbeton oder ähnlichen.Such components allow cantilevered concrete parts in particular balcony slabs, with the corresponding To connect false ceiling of a building, where the usual thermal bridges are largely eliminated will. Such components therefore settle in practice more and more and are now known in numerous embodiments. In general each insulating body is horizontal with several continuous tension and compression rods and if necessary still equipped with shear bars, the number of Reinforcing bars the length of the insulator and of those between the subsequent concrete components too transmitting forces is dependent. Here stand in particular the tension rods relatively far from the insulating body so that there is sufficient coverage with the connecting reinforcement of the components to be concreted on both sides is guaranteed. The tension rods are at their ends usually connected to their common crossbar Position relative to each other and relative to the insulating body to fix. This fixation can by Moldings are taken over that are fixed to the insulating body are connected and made of a harder material than this exist. While the insulating body from one Material such as polystyrene or a similar foam-like The strips are made of plastic, for example made of all-plastic, wood, fiber concrete or similar.

Die Leisten tragen damit wesentlich zur Stabilität des ganzen Isolierkörpers bei, so daß die Gefahr verringert wird, daß der Isolierkörper während des Transportes oder bei der Handhabung auf der Baustelle zerbricht.The strips thus contribute significantly to the stability of the whole insulating body, so that the risk is reduced that the insulating body during transport or breaks during handling on site.

Die Leisten haben dabei den Nachteil, daß sie aufgrund ihrer geringen Dicke die Bewehrungsstäbe nur auf sehr kurzen Abschnitten halten, so daß es möglich ist, daß die Bewehrungsstäbe sich unerwünscht axial in ihrer Position verschieben oder gar ganz aus der Leiste herausfallen.The strips have the disadvantage that they are due Due to their small thickness, the reinforcement bars are only very keep short sections so that it is possible that the reinforcing bars are undesirable axially in their Move position or even out of the bar fall out.

Aufgabe der vorliegenden Erfindung ist es daher, einen oben beschriebenen Isolierkörper dahingehend weiterzubilden, daß ein solches Verschieben oder gar Verlieren, d.h. Herausfallen der Bewehrungsstäbe aus dem Isolierkörper unterbunden wird. The object of the present invention is therefore a to further develop the insulating body described above, that such a postponement or even loss, i.e. The reinforcing bars fall out of the insulating body is prevented.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß in Erstreckungsrichtung der Bewehrungsstäbe seitlich neben den Ausnehmungen mit der Leiste verbundene Halterungen angeordnet sind, die das Herausfallen eines Bewehrungsstabes aus einer Ausnehmung verhindern.This object is achieved in that laterally in the direction of extension of the reinforcing bars brackets connected to the bar next to the recesses are arranged, the falling out of a reinforcing bar prevent from a recess.

Aufgrund dieser separaten Halterungen wird die Berührungsfläche zwischen den Bewehrungsstäben und der Leiste vergrößert, so daß hier größere Kräfte übertragen werden können. Daraus resultiert eine stärkere Fixierung des Bewehrungsstabes und es müssen erheblich höhere Kräfte als das Eigengewicht des Bewehrungsstabes aufgebracht werden, um ihn aus der Ausnehmung zu entfernen. Somit besteht kaum noch die Gefahr, daß auf der Baustelle ein Bauelement auftaucht, das während des Transportes einen Bewehrungsstab verloren hat.Because of these separate brackets, the contact surface between the reinforcing bars and the Bar enlarged, so that larger forces are transmitted here can be. This results in a stronger fixation of the rebar and it must be substantial higher forces than the weight of the reinforcing bar be applied to remove it from the recess. So there is hardly any danger that on the Construction site shows a component that during the Transportes lost a rebar.

Bei einer Ausführungsform, bei der die Ausnehmungen zu einer Leistenkante hin offene Schlitze und die seitlichen Halterungen in die gleiche Richtung hin offen sind, weisen die Halterungen an ihren Rändern federnde Elemente auf, mit denen die Öffnung der Halterung zumindest teilweise selbsttätig verschließbar ist. Die federnden Elemente weichen beim Eindrücken der Bewehrungsstäbe in die Leiste zurück und federn nach Passieren des Bewehrungsstabes in eine Position zurück, die eine Rückwärtsbewegung des Bewehrungsstabes blockiert. Insbesondere wenn die federnden Elemente sich im wesentlichen in Richtung der Schlitze erstrecken, ist eine funktionssichere Wirkungsweise möglich.In an embodiment in which the recesses are closed slits open on one edge of the ledge and the side ones Brackets open in the same direction are, the brackets have resilient at their edges Elements with which the opening of the bracket at least is partially self-locking. The resilient elements give way when the reinforcing bars are pressed in back into the bar and spring after passing the rebar to a position that blocked a backward movement of the rebar. Especially when the resilient elements are essentially Extend towards the slots is one reliable functioning possible.

Hierzu bietet es sich an, die Halterung aus zwei gegengleich ausgebildeten blattfederartigen Federelementen auszubilden. Da hierbei an der Halterung keine verschiebbaren oder beweglichen Teile angebracht sind, die sich beim selbsttätigen Rückfedern verklemmen könnten, ist dies eine sehr vorteilhafte Ausführungsform.For this purpose, it is advisable to make the bracket from two opposite trained leaf spring-like spring elements to train. Since there are no slidable on the bracket or moving parts attached could jam during the automatic springback, this is a very advantageous embodiment.

Bei einer anderen Halterung, bei der die Ausnehmungen der Leiste zu einer Leistenkante hin offene Schlitze sind, weisen die Halterungen seitlich von den Bewehrungsstäben Rastschienen auf, die mit sich quer zu den Ausnehmungen erstreckenden Verschlußkörpern zusammenwirken. Durch die Verwendung eines in Rastschienen einrastenden Verschlußkörpers wird ebenfalls eine sichere Fixierung des Bewehrungsstabes in den Ausnehmungen erreicht.With another bracket, in which the recesses the slits open to a ledge edge the brackets point to the side of the reinforcing bars Locking rails on, which are transverse to the Interaction extending locking bodies cooperate. By using one that snaps into the locking rails Closure body will also be a safe Fixation of the rebar in the recesses achieved.

Dabei ist es vorteilhaft, den Verschlußkörper und/oder die Rastschienen mit einer Vielzahl von hintereinander angeordneten Rastungen auszustatten, da der Verschlußkörper so bei Bewehrungsstäben unterschiedlicher Dicke verwandt werden kann. Wenn außerdem die Verschlußkörper und/oder die Ausnehmungen an ihren den Bewehrungsstäben zugewandten Seiten V-förmig ausgebildet sind, kann bei unterschiedlich dicken Bewehrungsstäben außerdem eine in der Ausnehmung zentrische Lagerung des Bewehrungsstabes erreicht werden, was bezüglich der Maßhaltigkeit des Bauelements im Hinblick auf die Anschlußbewehrungen der zu betonierenden Bauteile vorteilhaft ist.It is advantageous to the closure body and / or the locking rails with a variety of one behind the other arranged detents to equip since the closure body so with reinforcing bars of different thickness can be used. If also the closure body and / or the recesses on their reinforcing bars facing sides are V-shaped, can be reinforcement bars of different thickness also one in the recess centric bearing of the reinforcing bar be achieved in terms of dimensional accuracy of the component with regard to the connection reinforcements the components to be concreted is advantageous.

Bei einer weiteren Ausführungsform sind die Halterungen als mit der Leiste verbindbare Manschetten an den Bewehrungsstäben angeformt. Damit wird eine besonders wiederstandsfähige Halterung erreicht. In a further embodiment, the brackets as cuffs that can be connected to the bar on the reinforcing bars molded. This makes one special resistant bracket reached.

Insbesondere können die Manschetten als Spritzteil direkt um die Bewehrungsstäbe herumgeformt werden, wodurch sich zwischen Manschette und Bewehrungsstab eine sehr innige Verbindung ergibt, die für die Fixierung des Bewehrungsstabes von Vorteil ist. Insbesondere ist durch die innige Verbindung von Bewehrungsstab und Manschette dann eine axiale Verschiebung des Bewehrungsstabes bezüglich der Manschette und damit der Leiste ausgeschlossen.In particular, the sleeves can be molded directly around the reinforcing bars, whereby between the sleeve and reinforcement bar very intimate connection that results in the fixation of the reinforcing bar is an advantage. In particular is through the intimate connection of the reinforcing bar and the sleeve then an axial displacement of the reinforcing bar regarding the cuff and thus the groin locked out.

Um die Manschette dann mit der Leiste zu verbinden, kann sie einen dornartigen Fortsatz aufweisen, der mit einer Öffnung an der Leiste zusammenwirkt. Insbesondere wird hierzu vorgeschlagen, den dornartigen Fortsatz nach dem er durch die Öffnung hindurchgesteckt ist, nietmäßig aufzuweiten. Dies bietet sich insbesondere bei thermoplastischen Werkstoffen an.To connect the cuff to the bar it can have a spike-like extension that with an opening on the bar interacts. Especially the thorn-like extension is proposed for this purpose after it is inserted through the opening, rivet widening. This is particularly useful with thermoplastic materials.

In Figur 1 ist der untere Teil eines Bauelements zur Wärmedämmung zwischen einem Gebäude und einem vorkragenden Außenteil dargestellt. Er besteht im wesentlichen aus einem Isolierkörper 1 in den metallische Bewehrungsstäbe 2 integriert sind. Die Bewehrungsstäbe 2 erstrecken sich dabei quer zum Isolierkörper 1 durch diesen hindurch und stehen beidseits vor, wo sie mit der nicht dargestellten Anschlußbewehrung der zu betonierenden Bauteile verbunden werden. Der Isolierkörper 1 ist an seinem Ende durch eine U-Schiene 3 abgeschlossen, deren Schenkel durch Leisten 4 gebildet werden. Die U-Schiene besteht aus einem härterem Material als der üblicherweise aus Polystyrol oder ähnlichem bestehende Isolierkörper 1.In Figure 1, the lower part of a component is Thermal insulation between a building and a cantilever Outside part shown. It essentially exists from an insulating body 1 in the metallic reinforcing bars 2 are integrated. The reinforcement bars 2 extend transversely to the insulating body 1 through through this and stand out on both sides where they join the connecting reinforcement, not shown, of the concrete Components are connected. The insulating body 1 is closed at its end by a U-rail 3, whose legs are formed by strips 4. The U-rail is made of a harder material than which usually consists of polystyrene or the like Insulator 1.

Die Leisten 4, die die Schenkel der U-Schiene 3 bilden, weisen Ausnehmungen 5 auf, in denen der Bewehrungsstab 2 fixiert ist. Die Leisten 4 sind sehr schmal und tragen deswegen den Bewehrungsstab 2 nur auf einer sehr kurzen Strecke. Seitlich neben den Ausnehmungen erstrecken sich deswegen Halterungen 6, die den Bewehrungsstab 2 zusätzlich bezüglich der U-Schiene 3 und deren Leisten 4 fixieren.
In der Figur 2 ist hierzu zu erkennen, daß die Ausnehmungen 5 zur Leistenkante 7 hin offen sind, wobei die Halterungen 6 an den Rändern ihrer Öffnung federnde Elemente aufweist. Diese federnden Elemente werden durch blattfederartige Federelemente 8 gebildet. Beim Einbringen eines Bewehrungsstabes 2 in die Halterung biegen sich die Federelemente 8 zur Seite und lassen den Bewehrungsstab passieren. Dann schnappen sie in ihre Ursprungsposition zurück und versperren dem Bewehrungsstab seinen Rückweg, indem Sie die Öffnung der Halterung dabei zumindest teilweise selbsttätig wieder verschließen.
The strips 4, which form the legs of the U-rail 3, have recesses 5 in which the reinforcing bar 2 is fixed. The strips 4 are very narrow and therefore only carry the reinforcement bar 2 over a very short distance. For this reason, brackets 6 extend laterally next to the recesses and additionally fix the reinforcing bar 2 with respect to the U-rail 3 and its strips 4.
In this regard, it can be seen in FIG. 2 that the recesses 5 are open towards the ledge edge 7, the holders 6 having resilient elements at the edges of their opening. These resilient elements are formed by leaf spring-like spring elements 8. When inserting a reinforcement bar 2 into the holder, the spring elements 8 bend to the side and let the reinforcement bar pass. Then they snap back into their original position and block the reinforcement bar from returning by at least partially closing the opening of the bracket automatically.

Da auch das obere Ende des in Figur 1 dargestellten Isolierkörpers 1 mit einer entsprechenden U-Schiene abgeschlossen wird, können bei der Fertigung des Isolierkörpers die metallischen Bewehrungsstäbe jeweils in diese U-Schienen eingesetzt werden und die derart bestückten U-Schienen können dann z.B. von oben auf den Isolierkörper gestülpt werden, ohne daß dabei die Gefahr besteht, daß die Bewehrungsstäbe herausfallen.Since the upper end of that shown in Figure 1 Insulating body 1 with a corresponding U-rail can be completed in the manufacture of the insulating body the metallic reinforcement bars each in these U-rails are used and the so equipped U-rails can then e.g. from the top of the Insulation can be put over without the danger there is that the reinforcing bars fall out.

Eine andere Möglichkeit, Bewehrungsstäbe in der U-Schiene bzw. in deren Schenkel bildenden Leisten zu fixieren als in der Figur 1, ist in der Figur 3 dargestellt, in der gleiche Teile mit gleichen Bezugsziffern versehen sind. Another way to put reinforcement bars in the U-rail or in their legs forming strips fix as in Figure 1, is shown in Figure 3, in the same parts with the same reference numerals are provided.

Bei der in der Figur 3 dargestellten Variante weisen die sich seitlich an die Leisten 4 anschließenden Halterungen Rastschienen 9 auf. In der Figur 6, in der die Leisten der Figur 3 in der Seitenansicht dargestellt sind, erkennt man, daß diese Rastschienen mit einer Vielzahl von hintereinander angeordneten Rastungen 10 versehen sind. Diese Rastungen wirken zusammen mit Rastzähnen 11 an einem in den Figuren 4 und 5 dargestellten Verschlußkörper 12.Point in the variant shown in FIG. 3 the brackets adjoining the strips 4 on the side Locking rails 9 on. In Figure 6, in which the Last shown in Figure 3 in side view are, you can see that these locking rails with a A large number of catches 10 arranged one behind the other are provided. These detents work together with Locking teeth 11 on one shown in Figures 4 and 5 Closure body 12.

Der in die hier V-förmig ausgebildete Ausnehmung eingelegte Bewehrungsstab 2 liegt so tief wie es ihm möglich ist in diesen Ausnehmungen. Dann wird der sich quer zu dieser Ausnehmung erstreckende Verschlußkörper 12 auf die Leisten 4 aufgesteckt. Dabei gleiten die Ränder der Ausnehmungen der Leiste 4 in Nuten 13, die am Verschlußkörper ausgebildet sind. Mit seiner ebenialls V-förmig ausgebildeten Unterseite 14 drückt dabei der Verschlußkörper 12 den Bewehrungsstab in die V-förmige Ausnehmung, wobei gleichzeitig die Rastzähne 11 sich mit den Rastungen 10 der Rastschienen 9 verhaken und ein Zurückgleiten des Verschlußkörpers verhindern.The inserted in the V-shaped recess here Reinforcement bar 2 is as deep as possible is in these recesses. Then it turns across this recess extending closure body 12 the strips 4 attached. The edges of the slide Recesses in the bar 4 in grooves 13 on the closure body are trained. With its also V-shaped bottom 14 presses the Closure body 12 the rebar in the V-shaped Recess, the locking teeth 11 at the same time hook with the catches 10 of the catch rails 9 and prevent the closure body from sliding back.

Durch die damit über den Verschlußkörper auf die Bewehrungsstäbe ausübbaren Anpreßkräfte wird bei einer wie oben beschriebenen Handhabung der U-Schiene mit eingelegten Bewehrungsstäben ein Herausgleiten der Bewehrungsstäbe verhindert.By the so on the closure body on the reinforcing bars exercisable contact pressure is at a handling of the U-rail as described above inserted reinforcing bars slipping out of the Reinforcement bars prevented.

Eine weitere Variante zur sicheren Fixierung eines Bewehrungsstabes ist in den Figuren 7 und 8 dargestellt, in der wieder gleiche Teile mit gleichen Bezugszeichen versehen sind. Hier sind an den Bewehrungsstab 2 Manschetten 15 angeformt, die mit den Leisten 4 verbindbar sind. Die Manschetten umgreifen den Bewehrungsstab 2 an seinem ganzen Umfang, wie in der Figur 8 dargestellt ist. Sie können insbesondere als Kunststoffteile direkt an diese Bewehrungsstäbe angespritzt werden.Another variant for securely fixing a rebar is shown in Figures 7 and 8, in the same parts with the same reference numerals are provided. Here are 2 sleeves on the reinforcement bar 15 integrally formed, which can be connected to the strips 4 are. The sleeves grip the reinforcement bar 2 its entire extent, as shown in Figure 8 is. They can be used directly as plastic parts are injection molded onto these reinforcing bars.

An ihrem unteren Ende weist die Manschette 15 einen dornartigen Fortsatz 16 auf, der durch eine Öffnung 17 an der U-Schiene 3 hindurchragt. Da die Manschette aus thermoplastischen Kunststoff geformt ist, kann der aus der Öffnung 17 herausragende Abschnitt des dornartigen Fortsatzes wie links dargestellt zu einem pilzförmigen Kopf 18 verformt werden, so daß die Manschette fest mit der U-Schiene 3 und damit den Leisten 4 verbunden ist. Damit der pilzförmige Kopf 18 nicht an der Außenseite der U-Schiene aufträgt, weist diese im Bereich der Öffnung 17 eine Vertiefung 19 auf, in der der pilzförmige Kopf 18 zu liegen kommt ohne auf die Außenkontour der Schiene aufzutragen.At its lower end, the cuff 15 has one thorn-like extension 16 which through an opening 17th protrudes through the U-rail 3. Because the cuff is off thermoplastic is molded, can be made of the opening 17 projecting portion of the thorn-like Extension as shown on the left to a mushroom-shaped Head 18 are deformed so that the cuff is firm with the U-rail 3 and thus the strips 4 is connected. So that the mushroom-shaped head 18 is not on the outside applies the U-rail, this has in the area of the opening 17 a recess 19 in which the mushroom-shaped Head 18 comes to lie without the outer contour of the Rail to apply.

Nachdem also der Bewehrungsstab 2 mit entsprechenden Manschetten 15 versehen ist, wird er mit diesem in die U-Schiene 3 eingeführt und über die Fortsätze 16 fest mit der Schiene verbunden. Damit ist auch bei dieser Variante eine beliebige Handhabung der mit metallischen Bewehrungsstäben versehenen U-Schiene möglich, ohne daß die Gefahr besteht, daß die metallischen Bewehrungsstäbe aus der U-Schiene 3 bzw. den Leisten 4 herausfallen.So after the rebar 2 with appropriate Cuffs 15 is provided, he is with this in the U-rail 3 inserted and fixed over the extensions 16 connected to the rail.
