The transverse force bar has a bending radius which is smaller than double the diameter of the bar.

Description

Die Erfindung betrifft ein Bauelement zur Wärmedämmung zwischen zwei Bauteilen, insbesondere zwischen einem Gebäude und einem vorkragenden Außenteil, bestehend aus einem dazwischen zu verlegenden Isolierkörper mit zumindest einem Druckelement und einem Querkraftstab, die jeweils quer zur Längserstreckung des Isolierkörpers durch diesen hindurchlaufen, wobei das Druckelement über endständige Druckplatten in Wirkverbindung mit beiden Bauteilen steht, und wobei der Querkraftstab ausgehend von der Gebäudeseite schräg von oben nach unten durch den Isolierkörper hindurchläuft und beidseits in die Bauteile vorsteht.The invention relates to a component for thermal insulation between two Components, especially between a building and a cantilever Outer part, consisting of an insulating body to be laid between them with at least one pressure element and a shear bar, the each run through the insulating body transversely to the longitudinal extent thereof, wherein the pressure element via terminal pressure plates in There is an operative connection with both components, and the transverse force rod starting from the building side diagonally from top to bottom through the Insulator runs through and protrudes into the components on both sides.

Bisher wurden viele Versuche unternommen, derartige Bauelemente einbaufreundlicher zu gestalten, wozu insbesondere versucht wurde, eine Kollision der Bewehrungsstäbe wie Zug- und Druckelemente mit der Anschlußbewehrung auszuschließen. Beispielsweise wurde vorgeschlagen, die Druckstäbe gar nicht bzw. nur geringfügig in die angrenzenden Bauteile vorstehen zu lassen, um bei der Anschlußbewehrung des jeweiligen angrenzenden Bauteils nicht auf die Position der Druckelemente achten zu müssen. Verändert man die jeweiligen Bewehrungselemente, so besteht das Problem darin, daß die jeweilige Funktion der Bewehrungselemente durch die Umgestaltung bzw. konstruktive Änderung nicht beeinträchtigt werden darf. Ein weiteres Bauelement gemäß dem Oberbegriff des Anspruch 1 wird in DE-A-43 02 682 vorgestellt.So far, many attempts have been made to make such components easier to install to design, for which in particular an attempt was made Collision of the reinforcing bars such as tension and compression elements with the connecting reinforcement excluded. For example, it has been suggested the pressure rods not at all or only slightly into the adjacent components protrude to the connection reinforcement of the respective adjacent component do not pay attention to the position of the pressure elements have to. If you change the respective reinforcement elements, there is the problem is that the respective function of the reinforcement elements not affected by the redesign or design changes may be. Another component according to the preamble of claim 1 is presented in DE-A-43 02 682.

Der vorliegenden Erfindung liegt nun die Aufgabe zugrunde, auch die Querkraftstäbe bezüglich der Einbauverhältnisse zu verbessern, um hierdurch das Bauelement zur Wärmedämmung noch einbaufreundlicher zu gestalten, ohne auf der anderen Seite eine Herabsetzung der von den Querkraftstäben übertragbaren Kräfte hervorzurufen.The present invention is based on the object, the To improve shear bars in terms of installation conditions, thereby the component for thermal insulation is even easier to install design without on the other hand reducing the Transverse forces cause transferable forces.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Auflagerelement zur gegenseitigen kraftübertragenden Abstützung auf einem Abschnitt des Querkraftstabes aufliegt, und daß der Querkraftstab im Bereich des vorkragenden Außenteils nach Unterquerung des Auflagerelementes nach oben abgewinkelt ist und in Richtung der Zugzone verläuft.This object is achieved in that the support element for mutual force-transmitting support on a section of the shear bar rests, and that the transverse force rod in the area of the cantilever Angled upwards after passing under the support element and runs in the direction of the train zone.

Hierdurch ergibt sich der Vorteil, daß sich beide Bewehrungselemente gegenseitig bei der jeweiligen Kraftübertragung unterstützen, wobei insbesondere das Aufliegen des Auflagerelementes auf dem Querkraftstab dazu führt, daß der Querkraftstab in extremem Maße aus der Kollisionsgefahrenzone mit der Anschlußbewehrung herausgebogen werden kann, ohne daß dies zu Abplatzungen des Betons in diesem Abbiegungsbereich führt. Während üblicherweise eine Abbiegung des Querkraftstabes im Randbereich des vorstehenden Bauteiles maximal einen Biegedurchmesser aufweisen dürfte, der dem zehnfachen Stabdurchmesser entspricht, um ein Abplatzen des Betons zu vermeiden, führt die formschlüssige Verbindung von Auflagerelement und Querkraftstab in dem kritischen Bereich dazu, daß der Biegeradius nun nur noch dem etwa Zweifachen des Stabdurchmessers entsprechend bemessen sein kann.This has the advantage that the two reinforcement elements are mutually exclusive support in the respective power transmission, in particular the resting of the support element on the transverse force rod leads the shear bar to an extreme degree out of the collision hazard zone can be bent out with the connecting reinforcement without that this leads to flaking of the concrete in this area of the bend. While usually a bending of the shear bar in the edge area of the above component have a maximum of a bending diameter which corresponds to ten times the rod diameter by one The positive connection leads to preventing the concrete from flaking off of support element and shear bar in the critical area that the bending radius is now only about twice the rod diameter can be dimensioned accordingly.

Somit ist es möglich, den Querkraftstab im Bereich des vorkragenden Außenteils nach Unterquerung des Auflagerelementes stark abzuwinkeln, so daß dieser nach oben und zweckmäßigerweise in Vertikalrichtung bis zur Zugzone verläuft, wo er von der Vertikalerstreckung zweckmäßigerweise in eine Horizontalerstreckung übergeht und parallel zu einem dort angeordneten Zugstab verläuft. Hierdurch läßt sich sicher vermeiden, daß der Querkraftstab mit der Anschlußbewehrung des vorkragenden Außenteils kollidiert, indem er kurz nach Unterquerung des Auflagerelementes parallel zum Isolierkörper in einem Bereich nach oben verläuft, der noch nicht mit der Anschlußbewehrung versehen ist. Nach dem Eintritt in die Zugzone und einer weiteren Abwinkelung läuft dann der Querkraftstab parallel zu den dort angeordneten Zugstäben in das vorkragende Außenteil, um hierdurch die für die Kraftübertragung nötige Verankerung in dem Außenteil zu erhalten.It is thus possible to place the transverse force rod in the area of the projecting outer part after crossing under the support element, that this upwards and expediently in the vertical direction up to Zugzone runs where it expediently from the vertical extension in a horizontal extent passes over and parallel to one arranged there Tension rod runs. This can surely avoid that Shear bar with the connecting reinforcement of the projecting outer part collides by being parallel shortly after crossing under the support element to the insulating body in an area that is not yet up the connecting reinforcement is provided. After entering the train zone and a further bend then the shear force runs parallel the tension rods arranged there in the projecting outer part, in order to thereby the anchoring in the outer part necessary for the power transmission receive.

Das Auflagerelement ermöglicht durch die entsprechende Positionierung im Abwinklungsbereich des Querkraftstabes nicht nur eine Hinterfütterung des Querkraftstabes, sondern vor allem führt die kraftübertragende Verbindung mit dem Querkraftstab in vorteilhafter Weise dazu, daß die Kraft vom Auflagerelement in den Querkraftstab geleitet und dann hoch in die Zugzone übertragen wird, wodurch das Abplatzen des Betons im angesprochenen Bereich des stark verformten Querkraftstabes vermieden wird.The support element enables the appropriate positioning not only a backing in the bending area of the shear force of the shear force rod, but above all leads the force-transmitting connection with the transverse force rod in an advantageous manner that the force passed from the support element into the lateral force rod and then up into the Tensile zone is transmitted, causing the spalling of the concrete in the addressed Area of the highly deformed shear bar is avoided.

Was den Abwinklungsbereich betrifft, so empfiehlt es sich, wenn sich dieser zumindest unmittelbar an den Bereich der Unterquerung des Auflagerelementes anschließt und insbesondere zumindest teilweise mit diesem Unterquerungsbereich zusammenfällt, um hierdurch möglichst nahe am Auflagerelement und am Rand des vorkragenden Außenteils und außerhalb der Anschlußbewehrung kollisionsfrei vertikal nach oben zu verlaufen.As far as the range of angles is concerned, it is advisable if this at least directly to the area under the support element connects and in particular at least partially with this Crossing area coincides to thereby as close as possible to the Support element and on the edge of the projecting outer part and outside the connection reinforcement to run vertically upwards without collision.

Besonders vorteilhaft ist es, wenn der Querkraftstab mit dem Auflagerelement formschlüssig verbunden ist, das heißt, nicht nur in vertikaler, sondern auch in horizontaler quer zur Erstreckungsrichtung des Querkraftstabes verlaufender Richtung ist ein Übertragen von Kräften möglich, wodurch sich die erfindungsgemäßen Vorteile noch weiter verbessern lassen.It is particularly advantageous if the transverse force rod with the support element is positively connected, that is, not just vertically, but also in a horizontal direction transverse to the direction of extension of the shear bar forces can be transmitted in the direction, whereby the advantages of the invention can be further improved.

Am einfachsten ist es, wenn das Auflagerelement von einem Teil eines mit beiden Bauteilen zur Druckkraftübertragung in Wirkverbindung stehenden, sich horizontal durch den Isolierkörper hindurcherstreckenden Druckelementes gebildet ist, nämlich insbesondere von einer endständig an das Druckelement angeführten Druckplatte, die bei den meisten Anwendungsfällen ohnehin in dem Bereich des umgebogenen Querkraftstabes anzuordnen ist.It is easiest if the support element is part of a part with two components that are operatively connected to transmit pressure force, horizontally extending through the insulating body pressure element is formed, namely in particular from one terminal to the Printing element cited printing plate, which in most applications to be arranged in the area of the bent shear bar anyway is.

Unabhängig davon kann jedoch auch das Auflagerelement beabstandet vom Druckelement im vorkragenden Außenteil angeordnet und zur besseren Lagefixierung zumindest an zwei Querkraftstäben angeschlossen sein.Independently of this, however, the support element can also be spaced apart arranged by the pressure element in the projecting outer part and for better Position fixation must be connected to at least two shear bars.

In jedem Fall ist die bevorzugte Erstreckungsrichtung des Auflagerelementes parallel zur Längserstreckung des Isolierkörpers, also in Horizontalrichtung senkrecht zu der von jedem einzelnen Querkraftstab gebildeten Ebene.In any case, the preferred direction of extension of the support element parallel to the longitudinal extent of the insulating body, that is to say in the horizontal direction perpendicular to that formed by each shear bar Level.

Darüber hinaus ist es besonders zweckmäßig, wenn der Querkraftstab die Druckplatte im Bereich ihrer horizontalen Mitte unterquert, um hierdurch eine symmetrische Kraftverteilung bzw. -übertragung zu erhalten, die frei von zusätzlichen horizontalen Querkräften ist. Gleichwohl ist hier auch eine horizontale Druckplatte denkbar, die von zwei oder mehreren Querkraftstäben unterquert wird, wodurch zusätzliche horizontale Kräfte nicht auftreten können.In addition, it is particularly useful if the shear bar Pressure plate traversed in the area of its horizontal center to thereby to get a symmetrical power distribution or transmission that is free of additional horizontal transverse forces. Nevertheless, there is also one horizontal pressure plate conceivable, that of two or more shear bars is crossed under, which does not result in additional horizontal forces may occur.

Was die Unterquerung betrifft, so sollte diese auf jeden Fall so erfolgen, daß eine kraftübertragende Auflage auf dem Querkraftstab ermöglicht ist, wobei folglich die Unterquerung nicht nur den unteren Druckplattenbereich meint, sondern auch aus einer Durchquerung der Druckplatte bestehen kann in einem höheren Bereich der Druckplatte, der die Kraftübertragung noch begünstigt. Somit kann die Druckplatte eine Aussparung zur Durchquerung des Querkraftstabes aufweisen, die entweder allseits umschlossen und an den Querschnitt des Querkraftstabes angepaßt ist und so den Formschluß mit dem Querkraftstab herstellt, oder die insbesondere nach unten offen ist, um so das vertikale Ineinanderstecken von Druckplatte und Querkraftstab zu ermöglichen. Die formschlüssige Verbindung könnte in diesem Fall über eine Rastverbindung erfolgen, wobei dann die Druckplatte den Querkraftstab seitlich und an dessen Oberseite umgibt und nach dem Einstecken festlegt.As far as the crossing is concerned, it should definitely be done that a force-transmitting support on the transverse force rod is possible, consequently, the underpass not only the lower pressure plate area means, but also consist of crossing the pressure plate can be in a higher area of the pressure plate, which is the power transmission still favored. Thus, the pressure plate can have a recess for crossing of the transverse force rod, which either enclosed on all sides and is adapted to the cross section of the transverse force rod and so the Form-fit with the transverse force rod, or the particular after is open at the bottom, so that the vertical insertion of the pressure plate and Allow shear bar. The positive connection could in this case take place via a snap connection, the pressure plate then surrounds the lateral force rod on the side and on its upper side and after the insertion.

Die formschlüssige Verbindung weist gegenüber einer stoffschlüssigen Verbindung wie beispielsweise einer Schweißverbindung den Vorteil auf, daß diese bei gleicher Kraftübertragung viel einfacher zu montieren ist, was sich vor allem bei einer Endmontage der Bauelemente zur Wärmedämmung auswirkt.The positive connection points towards a material connection Connection such as a welded joint has the advantage that it is much easier to assemble with the same power transmission, which is especially important when the components for thermal insulation are finally assembled effect.

Um die Druckplatte in ihrer horizontalen Mitte unterqueren zu können, empfiehlt es sich, daß der Querkraftstab das Druckelement auch im Bereich des Isolierkörpers durchquert, wozu das Druckelement beispielsweise aus zwei über die gemeinsamen Druckplatten miteinander verbundenen Druckstäben bestehen kann oder beispielsweise aus einem verformten Flachstab mit einer entsprechenden Aussparung zur Durchquerung des Querkraftstabes durch das Druckelement. Dieser Flachstab kann an zumindest einem Ende mit einer Druckplatte versehen sein, die durch zumindest eine unmittelbar angeformte etwa vertikal verlaufende Abbiegung gebildet ist.In order to pass under the pressure plate in its horizontal center, it is recommended that the shear bar also push the pressure element in the area of the insulating body, for which purpose the pressure element, for example from two connected to each other via the common pressure plates Compression bars can consist of, for example, a deformed Flat bar with a corresponding recess for crossing the Shear force through the pressure element. This flat bar can at least be provided at one end with a pressure plate through at least an immediately formed approximately vertically extending bend is formed is.

Figur 1 zeigt ein erfindungsgemäßes Bauelement zur Wärmedämmung 1, das zwischen einem (in Figur 1 rechts anzuordnenden) Gebäude und einem (in Figur 1 links anzuordnenden) vorkragenden Außenteil eingebaut wird. Hierzu weist es einen sich zwischen beiden Bauteilen erstreckenden Isolierkörper 2 sowie quer zur Längserstreckung des Isolierkörpers angeordnete Druckelemente 3, Querkraftstäbe 4 und Zugstäbe 5 auf. Diese Bewehrungselemente stehen jeweils aus dem Isolierkörper 2 vor und werden folglich in dem Beton des jeweiligen angrenzenden Bauteiles verankert.FIG. 1 shows a component according to the invention for thermal insulation 1, that between a building (to be arranged on the right in FIG. 1) and a building projecting outer part (to be arranged on the left in FIG. 1) becomes. For this purpose, it has an extending between the two components Insulating body 2 and arranged transversely to the longitudinal extent of the insulating body Pressure elements 3, shear bars 4 and 5 tension bars. This Reinforcement elements protrude from the insulating body 2 and are consequently anchored in the concrete of the respective adjacent component.

Während die Zugstäbe 5 einen geradlinigen horizontalen Verlauf aufweisen und weit bis in die Betonbauteile verlaufen, sind die Druckelemente 3 aus einem Flachstab gebildet, der endständige Druckplatten 6 aufweist, die durch vertikale Abbiegungen des Flachstabes gebildet sind. Die Druckelemente stehen geringfügig in die angrenzenden Betonbauteile vor. While the tension rods 5 have a straight, horizontal course and extend far into the concrete components, the pressure elements 3 are made a flat bar is formed which has terminal pressure plates 6 which are formed by vertical turns of the flat bar. The printing elements protrude slightly into the adjacent concrete components.

Was den Verlauf der Querkraftstäbe 4 anbelangt, so weisen diese auf der Seite des Gebäudes einen zu den Zugstäben parallelen Verlauf auf in einer etwas tieferen Position als die Zugstäbe, treten in dieser Höhenposition in den Isolierkörper ein, wo sie abgewinkelt schräg nach unten in Richtung des vorkragenden Außenteils verlaufen, hierbei eine im Druckelement 3 vorgesehen Aussparung 7 durchqueren und den Isolierkörper unterhalb des Druckelementes wieder verlassen. Anschließend durchqueren sie im Bereich des vorkragenden Außenteiles eine in der als Auflagerelement fungierenden Druckplatte 6 an ihrer Unterseite vorgesehene Öffnung 8 und verlaufen hinter dieser Öffnung vertikal nach oben, bis sie in der Zugzone auf dem Höhenniveau ihres Verlaufes auf der Gebäudeseite wieder horizontal abgewinkelt in einen zu den Zugstäben 5 parallelen Verlauf übergehen und weiter in das vorkragende Außenteil verlaufen.As for the course of the shear bars 4, they point to the Side of the building along a course parallel to the tension rods slightly lower position than the tension rods, step in this height position into the insulator, where it angled obliquely down towards of the cantilevered outer part, here one in the pressure element 3 provided recess 7 traverse and the insulating body below leave the pressure element again. Then they cross in Area of the projecting outer part in the as a support element acting pressure plate 6 provided on its underside opening 8 and run vertically upwards behind this opening until they are in the draft zone horizontal again at the level of its course on the building side angled into a course parallel to the tension rods 5 and continue into the cantilevered outer part.

Während die Durchquerung des Druckelementes 3 innerhalb des Isolierkörpers keinen Einfluß auf die gegenseitigen Kraftübertragungen hat, bewirkt das Unterqueren der Druckplatte 6 im Bereich der Öffnung 8 eine formschlüssige Verbindung von Querkraftstab 4 und Druckplatte 6, durch die sich die Druckplatte und somit das Druckelement auf dem Querkraftstab abstützt. Hierdurch wird der Vorteil erzielt, daß die Abbiegung des schräg nach unten gerichteten Verlaufs in den vertikalen, nach oben gerichteten Verlauf, bei der der Querkraftstab um ca. 130° umgebogen ist, nicht zu Abplatzungen führt, obwohl diese auf engstem Raum durchgeführt ist.During the crossing of the pressure element 3 within the insulating body has no influence on the mutual power transmissions passing under the pressure plate 6 in the area of the opening 8 a positive connection of transverse force rod 4 and pressure plate 6, by which is the pressure plate and thus the pressure element on the lateral force rod supported. This has the advantage that the turning of the diagonally downwards in the vertical, upwards Course in which the shear bar is bent by approx. 130 °, does not lead to spalling, although this takes place in a confined space is.

Ein alternatives Ausführungsbeispiel zeigen die Figuren 4 bis 7, in denen ein Bauelement 11 zur Wärmedämmung dargestellt ist, das aus einem Isolierkörper 12, Zugstäben 13, Querkraftstäben 14 sowie Druckelementen 15 besteht. Im Gegensatz zu der Ausführungsform aus den Figuren 1 bis 3 ist im hier vorliegenden Fall ein Auflagerelement 16 vorgesehen, das nicht aus Teilen der Druckelemente gebildet ist, sondern aus einem separaten Stababschnitt, der in Horizontalrichtung parallel zur Längserstreckung des Isolierkörpers verläuft. An alternative embodiment is shown in FIGS. 4 to 7, in which a component 11 for thermal insulation is shown, which consists of an insulating body 12, tension rods 13, transverse force rods 14 and pressure elements 15 consists. In contrast to the embodiment from Figures 1 to 3 in the present case, a support element 16 is provided, which is not is formed from parts of the printing elements, but from a separate one Rod section which is in the horizontal direction parallel to the longitudinal extension of the Insulator runs.

Dieses Auflagerelement 16 ist hierbei im Bereich seiner Enden auf zwei voneinander beabstandeten Druckelementen 15 aufgestützt, während es im Bereich der horizontalen Mitte auf dem umgebogenen Bereich des Querkraftstabes 14 liegt. Im einbetonierten Zustand sorgt dieses Berühren von Auflagerelement und Querkraftstab für die vorstehend geschilderten Vorteile der verbesserten Kraftübertragung einerseits und der besseren Umbiegbarkeit des Querkraftstabes ohne Abplatzen des Betons in dem umgebogenen Bereich andererseits.This support element 16 is in the region of its ends on two spaced apart pressure elements 15 supported while it in the area of the horizontal center on the bent area of the Shear bar 14 is. This touches the concrete of support element and shear bar for the above Advantages of the improved power transmission on the one hand and the better Bendability of the shear bar without chipping the concrete in the bent area on the other hand.

Die in den Figuren 12 bis 15 dargestellte Variante eines Bauelementes 31 mit einem Isolierkörper 32, Zugstäben 33, Querkraftstäben 34 und einem Auflagerelement 36 unterscheidet sich von diesem Ausführungsbeispiel aus den Figuren 4 bis 7 nur dadurch, daß das Auflagerelement nicht wie der Stababschnitt 16 eine zylindrische Form aufweist, sondern nur halbzylindrisch ausgebildet ist, wobei er mit seiner gerundeten Außenfläche in der Abbiegung zweier voneinander beabstandet verlaufender Querkraftstäbe 34 aufliegt, während die ebene Außenfläche horizontal orientiert ist und hierdurch eine bessere Angriffsfläche zur Kraftaufnahme vom vorkragenden Außenteil auf das Auflagerelement bietet. Außerdem ist das Auflagerelement aus den Figuren 12 bis 15 unabhängig von Druckelementen angeordnet.The variant of a component 31 shown in FIGS. 12 to 15 with an insulating body 32, tension rods 33, transverse force rods 34 and one Support element 36 differs from this embodiment from Figures 4 to 7 only in that the support element is not like the rod section 16 has a cylindrical shape, but only semi-cylindrical is formed, with its rounded outer surface in the bend of two spaced-apart transverse force bars 34 rests, while the flat outer surface is oriented horizontally is and thereby a better contact surface for absorbing force from the cantilever Offers outer part on the support element. Besides, that is Support element from Figures 12 to 15 regardless of pressure elements arranged.

Beim Ausführungsbeispiel aus den Figuren 8 bis 11 besteht ein Bauelement 21 zur Wärmedämmung aus einem Isolierkörper 22, Zugstäben 23, Querkraftstäben 24 und Druckelementen 25, wobei der zwei endständige Druckplatten 27 verbindende Druckstab 26 als Auflagerelement fungiert, indem er von dem Querkraftstab 24 unterquert wird. Da der Druckstab 26 genau senkrecht zur Längserstreckung des Isolierkörpers verläuft, muß der Querkraftstab hierzu - wie am besten aus Figur 10 erkennbar ist - einen seitlichen Versatz aufweisen, wodurch er von schräg oben aus dem Isolierkörper herauskommend auf der einen Seite des Druckstabes nach unten verläuft, ihn auf der Unterseite unterquert und dann auf der anderen Seite wieder nach oben vertikal in die Zugzone weiterläuft. Hierdurch erstreckt sich der im dem Gebäude zugeordneten Bauteil und im Isolierkörper verlaufende Abschnitt des Querkraftstabes in einer Ebene, die parallel zur Ebene ist, in der der dem vorkragenden Bauteil zugeordnete Abschnitt des Querkraftstabes verläuft.In the exemplary embodiment from FIGS. 8 to 11, there is a component 21 for thermal insulation from an insulating body 22, tension rods 23, Shear bars 24 and pressure elements 25, the two terminal Pressure plate 26 connecting pressure plates 27 acts as a support element, by being traversed by the transverse force rod 24. Since the pressure rod 26 runs exactly perpendicular to the longitudinal extension of the insulating body, must the shear force rod for this - as can best be seen from FIG. 10 - one have lateral offset, which makes it from the top Insulator coming out on one side of the pressure rod runs below, passes under it on the underside and then on the other Side up again vertically into the train zone. This extends the component assigned to the building and the insulating body extending section of the shear bar in a plane that is parallel to the plane in which the section assigned to the projecting component of the shear force runs.

Die Figuren 16 bis 19 zeigen schließlich noch ein Ausführungsbeispiel eines Bauelementes 41 zur Wärmedämmung, bei dem ein Auflagerelement 46 insgesamt drei Querkraftstäbe 44 beaufschlagt und hierzu aus einer gemeinsamen Druckplatte für vier Druckelemente 45 besteht. Es sei angemerkt, daß sich das Auflagerelement 46 in Form der gemeinsamen Druckplatte auch über die gesamte Bauelementlänge erstrecken kann, die üblicherweise 100 cm beträgt.FIGS. 16 to 19 finally show an exemplary embodiment of a Component 41 for thermal insulation, in which a support element 46 applied a total of three shear bars 44 and this from one common printing plate for four printing elements 45 there. It should be noted that the support element 46 in the form of the common Pressure plate can also extend over the entire length of the component is usually 100 cm.

Das Auflagerelement 46 weist im unteren Bereich Aussparungen 48 auf, durch die sich die Querkraftstäbe 44 mit ihrem das Auflagerelement unterquerenden Abschnitten erstrecken, wobei die Aussparungen 48 eine dem Stabdurchmesser der Querkraftstäbe angepaßte Breite aufweisen und hierdurch einen formschlüssigen Verbund zwischen Auflagerelement und Querkraftstäben ermöglichen.The support element 46 has cutouts 48 in the lower region, through which the transverse force bars 44 with their traversing the support element Sections extend, the recesses 48 one of the Have rod diameter of the transverse force bars adapted width and hereby a positive connection between the support element and Enable shear bars.

Durch das spezielle Anpassen der Druckelemente und Querkraftstäbe läßt sich nun in erfindungsgemäßer Art und Weise der Verlauf der Querkraftstäbe auf der Seite des vorkragenden Außenteiles derart nach oben in die Zugzone verlegen, daß Kollisionen mit der Bewehrung des Außenteils vermieden werden können.Through the special adjustment of the pressure elements and shear bars the course of the transverse force bars now changes in the manner according to the invention on the side of the projecting outer part in such a way up move the tensile zone that collisions with the reinforcement of the outer part can be avoided.
