Abstract

The element consists of an insulation body (1) located between the two components (A,B). The insulation body has several shear force rods (4), which project through the components in the longitudinal direction of the insulation body. At least some of the shear rods extend in such a way that they are offset from each other in both the horizontal and the vertical plane.

Description

Die Erfindung betrifft ein Bauelement zur Wärmedämmung zwischen zwei Bauteilen, insbesondere zwischen einem Gebäude (A) und einem vorkragenden Außenteil (B), bestehend aus einem dazwischen zu verlegenden Isolierkörper, der zumindest Querkraftstäbe aufweist, die quer zur Längserstreckung des Isolierkörpers durch diesen hindurchlaufen und zumindest gebäudeseitig vorstehen, wobei sie den Isolierkörper - ausgehend von der Gebäudeseite - schräg von oben nach unten durchqueren.The invention relates to a component for thermal insulation between two Components, especially between a building (A) and a cantilever Outer part (B), consisting of one to be installed in between Insulating body that has at least shear bars that are transverse to the longitudinal extent of the insulating body run through it and at least protrude on the building side, taking the insulating body - starting from the Building side - cross diagonally from top to bottom.

Derartige Bauelemente gestatten es, vorkragende Außenteile, insbesondere Balkonplatten, mit der entsprechenden Zwischendecke eines Gebäudes zu verbinden, wobei die sonst üblichen Wärmebrücken weitestgehend durch den zwischengeschalteten Isolierkörper eliminiert werden. Sie setzen sich daher in der Praxis immer stärker durch und sind inzwischen in zahlreichen Ausführungsformen bekannt. Dabei sind die Isolierkörper neben den genannten Querkraftstäben im allgemeinen auch mit Zugstäben und Druckstäben bestückt, damit das vorkragende Außenteil keiner weiteren Abstützung bedarf. Falls das Außenteil jedoch an seinem Ende abgestützt wird, kann auf die Zugstäbe verzichtet werden. Hingegen sind die Druckstäbe in beiden Fällen notwendig, um ein Zusammendrücken des Isolierkörpers zu verhindern.Such components allow cantilevered outer parts, in particular Balcony slabs, with the corresponding false ceiling of a building to connect, the usual thermal bridges as far as possible be eliminated by the intermediate insulating body. you put are becoming increasingly popular in practice and are now popular numerous embodiments are known. The insulators are next to it the shear bars mentioned generally also with tension bars and pressure rods so that the cantilevered outer part does not have any more Support is needed. However, if the outer part is supported at its end the tension rods can be dispensed with. On the other hand, they are Push rods in both cases necessary to compress the To prevent insulating body.

Mit der vorliegenden Erfindung sollen die genannten Bauelemente dahingehend verbessert werden, daß sie sich durch eine universellere Kraftaufnahme auszeichnen. With the present invention, the above-mentioned components are intended to this effect be improved in that they are characterized by a more universal force absorption award.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß - bezogen auf den horizontalen Einbau des Bauelementes - zumindest einige der Querkraftstäbe bei ihrer Durchquerung des Isolierkörpers aus der Vertikalebene herauslaufen, derart, daß die aus dem Isolierkörper austretenden Enden des Querkraftstabes nicht nur vertikal sondern auch horizontal gegeneinander versetzt sind.This object is achieved in that - based on the horizontal installation of the component - at least some of the shear bars when crossing the insulating body from the vertical plane run out in such a way that the ends emerging from the insulating body of the shear bar not only vertically but also horizontally against each other are offset.

Die Querkraftstäbe verlaufen also im Bereich des Isolierkörpers gegenüber der Vertikalebene etwas geneigt und können dadurch nicht nur reine Vertikalkräfte, sondern je nach ihrem Neigungswinkel gegenüber der Vertikalebene auch Kräfte in Horizontalrichtung, parallel zum Isolierkörper, aufnehmen. Derartige Kräfte quer zur Stablängsrichtung können bei Wind- bzw. Erdbebenbelastung auf das vorkragende Außenteil vorkommen. Weiterhin haben Untersuchungen der Anmelderin ergeben, daß vor allem bei Anschlüssen von Stahlträgern horizontale Stabilisierungskräfte auftreten. Schließlich können aufgrund unterschiedlicher Wärmedehnung des -vorkragenden Außenteils gegenüber dem Gebäude horizontale Zwängungskräfte vorkommen. All diese Kräfte werden bisher über Biegebeanspruchung von den Bewehrungsstäben aufgenommen. Durch diese Beanspruchung können bei einer elastischen Bemessung die Querschittsflächen der Bewehrungsstäbe nicht optimal ausgenutzt werden.The shear bars therefore run opposite each other in the area of the insulating body slightly inclined on the vertical plane and can therefore not only but depending on their angle of inclination to the vertical plane also absorb forces in the horizontal direction, parallel to the insulating body. Such forces transverse to the longitudinal direction of the bar can Earthquake loads occur on the projecting outer part. Farther Investigations by the applicant have shown that, above all, for connections horizontal stabilizing forces occur from steel beams. Finally, due to different thermal expansion of the protruding External constraining forces in relation to the building occurrence. All of these forces have so far been subjected to bending stress taken up by the reinforcing bars. Because of this strain can the cross-sectional areas of the Reinforcing bars are not used optimally.

Demgegenüber gestattet die erfindungsgemäße Ausbildung der Querkraftstäbe eine wesentlich stabilere Fixierung des Außenteiles und die bisherige Biegebeanspruchung der Bewehrungsstäbe, bei der es sich häufig um eine wiederkehrende Biegewechsel-Belastung handelt, entfällt. Die Bewehrungsstäbe unterliegen somit nur noch einer reinen Normalkraftbeanspruchung, so daß die Querschnittsfläche der den Isolierkörper durchdringenden Stäbe auf ein Minimum reduziert werden kann.In contrast, the design of the transverse force bars allows a much more stable fixation of the outer part and the previous one Bending stress on the reinforcing bars, which is common a recurring bending load is not applicable. The Reinforcing bars are therefore only subject to a normal load, so that the cross-sectional area of the penetrating the insulating body Bars can be reduced to a minimum.

Die Neigung der Querkraftstäbe gegenüber der Vertikalebene hängt, wie gesagt, von den zu erwartenden Querkräften ab. Untersuchungen der Anmelderin haben ergeben, daß eine Schrägstellung von 3° bis 35° ausreichend ist, wobei ein Winkel zwischen etwa 10° bis etwa 25° vorzuziehen ist.The inclination of the shear bars relative to the vertical plane depends on how said, depending on the expected transverse forces. Investigations by the applicant have shown that an inclination of 3 ° to 35 ° is sufficient is preferable, with an angle between about 10 ° to about 25 ° is.

Eine besonders zweckmäßige Weiterbildung der Erfindung besteht darin, die jenigen Querkraftstäbe, die erfindungsgemäß schräg gestellt werden, jeweils paarweise spiegelbildlich, also entgegengesetzt zueinander anzuordnen. Auf diese Weise kompensieren sich die bei Vertikalbelastung auftretenden horizontalen Reaktionskräfte, d.h., daß die angeschlossenen Bauteile keine resultierende Horizontalbeanspruchung erfahren.A particularly expedient development of the invention consists in those shear bars that are tilted according to the invention, to be arranged in pairs in mirror image, i.e. opposite to each other. In this way, those that occur under vertical loading are compensated for horizontal reaction forces, i.e. that the connected Components experience no resulting horizontal stress.

Eine andere vorteilhafte Weiterbildung der Erfindung besteht darin, die Neigung der Querkraftstäbe so zu wählen, daß sie sich von der Gebäudeseite zum vorkragenden Außenteil hin einander annähern. Dadurch sind die Querkraftstäbe außenteilseitig nur noch maximal etwa 5 cm, insbesondere etwa 2 cm bis etwa 4 cm voneinander entfernt, was besonders dann von Vorteil ist, wenn an Stelle eines Außenteiles aus Stahlbeton eine Holz- oder Stahlbau-Konstruktion an das Gebäude angeschlossen werden soll, weil der Anschluß dann nur lokal, quasi punktförmig, erfolgt und nicht flächenhaft wie bei einer Balkonplatte aus Beton.Another advantageous development of the invention is that Select the inclination of the shear bars so that they are from the building side approach each other towards the projecting outer part. Thereby the lateral force rods on the outer part side only a maximum of about 5 cm in particular about 2 cm to about 4 cm apart, especially then It is advantageous if, instead of an outer part made of reinforced concrete, a wooden or steel structure to be connected to the building, because the connection is then only local, quasi punctiform, and not extensive like a concrete balcony slab.

Zu dem gleichen Zweck empfiehlt es sich auch, daß die außenteilseitigen Enden zumindest eines Paares von Querstäben sowie die benachbarten Druckstabenden und gegebenenfalls benachbarte Zugstabenden mit einer gemeinsamen Befestigungsvorrichtung, insbesondere Befestigungsplatte verbunden sind. An diese Befestigungsplatte können dann vorkragende Holz- oder Stahlbauteile montiert werden, und zwar zweckmäßig unter Zwischenschaltung einer auf die Befestigungsplatte passenden Anschlußplatte. Insoweit sei zur Vermeidung von Wiederholungen auf die am gleichen Tage eingereichte Patentanmeldung "Bauelement zur Wärmedämmung" der selben Anmelderin verwiesen, auf die vollinhaltlich Bezug genommen wird.For the same purpose, it is also recommended that the outer part Ends of at least one pair of cross bars as well as the neighboring ones Compression rod ends and possibly adjacent tension rod ends with a common fastening device, in particular fastening plate are connected. Projecting can then on this mounting plate Wooden or steel components are mounted, conveniently under Interposition of a connection plate that fits onto the mounting plate. In this regard, to avoid repetitions, the same Days filed patent application "component for thermal insulation" referred to the same applicant, to which reference is made in full becomes.

Die Verbindung der Querkraftstabenden mit der Befestigungsplatte erfolgt vorzugsweise derart, daß die Querkraftstäbe schräg auf die Befestigungsplatte treffen, d.h., daß die Querkraftstäbe an ihrem außenteilseitigen Ende nicht wieder in die Horizontalebene zurückgebogen werden brauchen. Sie können entweder durch die Befestigungplatte hindurchgehen und mit ihr verschraubt oder verschweißt werden oder die Befestigungsplatte weist angeformte schräge Stümpfe auf, die mit den schräg ankommenden Querkraftstäben korrespondieren und an der Stoßstelle stumpf verschweißt werden.The connection of the shear rod ends to the mounting plate is done preferably such that the transverse force bars are inclined on the mounting plate meet, i.e. that the shear bars at their outer part end do not need to be bent back into the horizontal plane. she can either go through the mounting plate and with it screwed or welded or the mounting plate has molded on oblique stumps, with the obliquely arriving shear bars correspond and butt welded at the joint become.

Statt dessen können die Querkraftstäbe aber auch mit einer Befestigungsvorrichtung in Form eines Winkels oder in anderer Form verbunden werden. Hierzu wird auf die DE 195 28 130 verwiesen, auf die ebenfalls voll inhaltlich Bezug genommen wird.Instead, the shear bars can also be used with a fastening device be connected in the form of an angle or in another form. For this purpose, reference is made to DE 195 28 130, which is also full reference is made to the content.

Der Übergang von dem gegenüber der Vertikalebene geneigten Verlauf des Querkraftstabes in den horizontalen Verlauf, der zumindest gebäudeseitig, in zahlreichen Anwendungsfällen aber auch außenteilseitig zu realisieren ist, erfolgt zweckmäßig über einen Bogen, insbesondere Kreisbogen, wobei es besonders günstig ist, diesen Bogen auch gleich für den Übergang von dem gegenüber der Horizontalebene geneigten Verlauf des Querkraftstabes in die Horizontalebene zu verwenden. Man kommt dadurch für beide Schrägstellungen mit ein und demselben Bogen aus.The transition from the course inclined to the vertical plane of the transverse force rod in the horizontal course, at least on the building side, to be implemented on the outside in numerous applications is advantageously carried out via an arc, in particular a circular arc, it is particularly cheap to have this bow for the same Transition from the inclined course of the Use shear force in the horizontal plane. You come through it for both inclinations with the same arch.

Zur optimalen Krafübertragung empfiehlt es sich, daß die bogenförmigen Übergänge stets außerhalb des Isolierkörpers liegen und somit im Beton abgestützt werden.For optimal power transmission, it is recommended that the arcuate Transitions are always outside the insulating body and therefore in the concrete be supported.

Schließlich besteht noch eine Weiterbildung der Erfindung darin, überstehende Enden der Querkraftstäbe mit zumindest einem parallel und beabstandet zum Isolierkörper verlaufenden Querverteilerstab in Wirkverbindung zu bringen. Dies kann derart erfolgen, daß die Qerkraftstabenden mit dem Querverteilerstab verschweißt oder verrödelt werden oder daß der Querverteilerstab in unmittelbarer Nachbarschaft zu den Enden der Querkraftstäbe verlegt wird, so daß die gewünschte Wirkverbindung über den Betonverbund erzeugt wird. Finally, a further development of the invention consists in projecting Ends of the shear bars with at least one parallel and spaced in operative connection to the transverse distributor rod which runs bring to. This can be done in such a way that the force rod ends with the transverse distributor rod are welded or bridled or that the Cross distribution bar in the immediate vicinity of the ends of the shear bars is moved so that the desired active connection via the Concrete composite is generated.

Anstelle des vorgenannten Querverteilerstabes, der mit einem gewissen Abstand zum Isolierkörper angeordnet ist, kann man auch mit einer Platte arbeiten, in welche die Querkraftstäbe hineinlaufen. Bei dieser Platte kann es sich insbesondere um die weiter oben beschriebene Befestigungsvorrichtung handeln.Instead of the above-mentioned crossbar, which with a certain Distance to the insulator is also possible with a plate work into which the shear bars run. This plate can it is in particular the fastening device described above act.

Das in den Figuren 1 bis 3 dargestellte Bauelement besteht aus einem länglichen, rechteckigen Isolierkörper 1, der in seinem oberen Bereich mit einer Vielzahl von Zugstäben 2 und in seinem unteren Bereich mit der gleichen Anzahl von Druckstäben 3 bestückt ist. Während die Zugstäbe 2 sich weit in die beiden angrenzenden Betonbauteile, also in das mit A angedeutete Gebäude einerseits und das mit B angedeutete vorkragende Außenteil B andererseits hineinerstrecken, haben die Druckstäbe 3 nur relativ kurze Überstände gegenüber dem Isolierkörper 1 und sind dafür an ihren Enden mit Ankerplatten 3a versehen.The component shown in Figures 1 to 3 consists of a elongated, rectangular insulating body 1 with in its upper region a plurality of tension rods 2 and in its lower area with the same Number of pressure rods 3 is equipped. While the tension rods 2 themselves far into the two adjacent concrete components, i.e. into the one indicated with A. The building on the one hand and the protruding outer part, indicated with a B. B on the other hand, have the pressure rods 3 only relative short protrusions from the insulating body 1 and are on their Provide ends with anchor plates 3a.

Außerdem ist der Isolierkörper 1 mit mehreren Querkraftstäben 4 bestückt, die von der Gebäudeseite A etwa in Höhe der Zugstäbe in den Isolierkörper eintreten, im Inneren des Isolierkörpers schräg nach unten laufen und etwa auf Höhe der Druckstäbe 3 aus dem Isolierkörper austreten und in das vorkragende Bauteil weiterlaufen. In addition, the insulating body 1 is equipped with a plurality of shear bars 4, from the building side A at about the height of the tension rods in the insulating body enter, run diagonally downwards inside the insulator and emerge from the insulating body at about the height of the pressure rods 3 and into the projecting component continues to run.

Wesentlich ist nun, daß diese Querkraftstäbe 4 nicht nur diesen üblichen Versatz von oben nach unten aufweisen, sondern außerdem auch einen Versatz bezüglich der Vertikalebene. Man erkennt den gegenüber der Vertikalebene geneigten Verlauf der Querkraftstäbe 4 in den Figuren 1 und 3. Der Winkel, mit dem die Querkraftstäbe gegenüber der Vertikalebene geneigt sind, beträgt im Ausführungsbeispiel etwa 20°.It is essential that these shear bars 4 not only this usual Have an offset from top to bottom, but also one Offset from the vertical plane. You can see that compared to the vertical plane inclined course of the transverse force rods 4 in FIGS. 1 and 3. The angle at which the shear bars are inclined relative to the vertical plane are about 20 ° in the exemplary embodiment.

Desweiteren erkennt man in den Figuren 1 und 3, daß die Querkraftstäbe nicht in der gleichen Richtung geneigt sind, sondern daß die eine Hälfte in der einen Richtung, die andere Hälfte entgegengesetzt dazu geneigt ist.Furthermore, one can see in Figures 1 and 3 that the shear bars are not inclined in the same direction, but that one half in one direction, the other half is inclined in the opposite direction.

Statt des gezeichneten Ausführungsbeispieles, wo die Querkraftstäbe gleicher Neigung gruppenweise zusammengefaßt sind, können sie auch abwechselnd aufeinanderfolgen. Die letztgenannte Bauform empfiehlt sich dann, wenn die Bewährungselemente außenteilseitig möglichst konzentriert werden sollen, etwa um sie mit einer gemeinsamen Befestigungvorrichtung zu verbinden. Eine solche Bauform ist in den Figuren 4 und 5 dargestellt.Instead of the illustrated embodiment, where the shear bars are the same Inclination are grouped in groups, they can also alternate successive. The latter design is recommended when the probation elements are concentrated on the outside as much as possible should be around them with a common fastening device connect to. Such a design is shown in Figures 4 and 5.

Der Isolierkörper 1 ist hier quaderförmig und wesentlich kürzer als bei dem zuvor geschriebenen Bauelement. Er ist Figur 4 aus Übersichtlichkeitsgründen nur durch einige strichpunktierte Linien angedeutet.The insulating body 1 is cuboid here and much shorter than that previously written component. It is Figure 4 for reasons of clarity only indicated by a few dash-dotted lines.

Wie man insbesondere in Figur 4 erkennen kann, münden die Druckstäbe 3 und die Querkraftstäbe 4 nach Durchquerung des Isolierkörpers in eine gemeinsame Befestigungsvorrichtung 5, die plattenartig ausgebildet ist und an ihrer dem Isolierkörper 1 abgewandten Außenseite 5a eine plane vertikale Anlagefläche zum Anschluß des vorkragenden Außenteiles aufweist. Von diesem Außenteil erkennt man in Figur 4 eine Anschlußplatte 9, die vorzugsweise verstellbar an der Befestigungsvorrichtung 5 montiert werden kann. Dazu stützt sich die Befestigungsvorrichtung 5 über verstellbare Anschlagmuttern 6 an den ihr zugeordneten Druckstäben 3 ab. Durch Vor- oder Zurückdrehen der Muttern 6 auf den Druckstäben 3, die in diesem Bereich ein Gewinde aufweisen, läßt sich somit die Position wie auch die winklige Ausrichtung der Befestigungsvorrichtung 5 verstellen.As can be seen in particular in FIG. 4, the pressure rods 3 open out and the transverse bars 4 after crossing the insulating body in one common fastening device 5, which is plate-like and on its outer side 5a facing away from the insulating body 1, a flat vertical Has contact surface for connecting the projecting outer part. From this outer part can be seen in Figure 4, a connecting plate 9, the preferably adjustable to be mounted on the fastening device 5 can. For this purpose, the fastening device 5 is supported by adjustable stop nuts 6 on the pressure rods 3 assigned to it. By advance or turning back the nuts 6 on the pressure rods 3 in this area have a thread, the position as well as the Adjust the angular orientation of the fastening device 5.

In gleicher Weise könnte die Befestigungsvorrichtung 5 auch verstellbar mit den Zugstäben 2 verbunden werden. Im Ausführungsbeispiel laufen die Zugstäbe 2 jedoch durch bis zu der Anschlußplatte 9, wobei deren Position im Zugbereich ebenfalls durch die auf den Zugstäben angeordneten Muttern 6', die sich selbstverständlich auch auf dem rückwärtigen Teil der Anschlußplatte 9 befinden müssen, verstellbar ist.In the same way, the fastening device 5 could also be adjustable be connected to the tension rods 2. In the exemplary embodiment, the Tension rods 2, however, up to the connecting plate 9, the position of which in the pull area also by the nuts arranged on the pull rods 6 ', which of course is also on the rear part of the connection plate 9 must be located is adjustable.

Meist genügt es, wenn die Anschlußplatte 9 nur über die an den Zugstäben 2 angeordneten Muttern 6' verstellt werden kann. Dann brauchen die an den Druckstäben angeordneten Muttern 6 nicht mehr von außen zugänglich zu sein sondern können voll vom Isolierkörper 1 umschlossen sein. Außerdem können die Druckstäbe in diesem Fall auch direkt, unter Weglassung der Muttern 6 mit der Befestigungsvorrichtung 5 verschweißt werden. In beiden Fällen kann der Isolierkörper 1 bis zur Befestigungsvorrichtung 5 ragen und sich von dort vertikal nach oben estrecken; man erhält dann im oberen Bereich der Befestigungsvorrichtung 5 automatisch einen Zwischenraum, um die Muttern 6' verdrehen zu können.It is usually sufficient if the connecting plate 9 only on the on the tension rods 2 arranged nuts 6 'can be adjusted. Then they need to the pressure rods arranged nuts 6 are no longer accessible from the outside to be but can be fully enclosed by the insulating body 1. Moreover In this case, the pressure rods can also be omitted directly the nuts 6 are welded to the fastening device 5. In In both cases, the insulating body 1 can reach the fastening device 5 protrude and stretch vertically upwards from there; you then get in upper area of the fastening device 5 automatically a gap, to be able to turn the nuts 6 '.

Alternativ kann auch auf eine Verbindung der Befestigungsvorrichtung 5 mit den Druckstäben 3 verzichtet werden, etwa indem sich das Außenteil, im Ausführungsbeispiel also dessen Anschlußplatte 9 direkt an den Druckstäben 3 abstützt.Alternatively, the fastening device 5 can also be connected can be dispensed with the pressure rods 3, for example by the outer part, in the exemplary embodiment, therefore, its connecting plate 9 directly on the pressure rods 3 supports.

An ihrer Oberseite ist die Befestigungsvorrichtung 5 mit einer horizontalen Auflagefläche 5c versehen, auf die ein an der Anschlußplatte 9 montierter Vorsprung 9a aufgelegt werden kann. Man erhält dadurch eine formschlüssige Übertragung der vertikalen Querkräfte. Außerdem gestattet es diese Anordnung, die Anschlußplatte 9 in ihrer Höhe zu nivellieren, indem zwischen die Auflagefläche 5c und den Vorsprung 9a Distanzplättchen 23 gelegt werden. Je nach dem gewünschten Ausmaß der Höhennivellierung ist es empfehlenswert, die Durchgangsöffnungen in der Anschlußplatte 9 für die Bewehrungsstäbe als Langlöcher auszubilden. Man erhält somit eine optimale Verstellbarkeit des vorkragenden Außenteils, und zwar nicht nur horizontal und vertikal, sondern auch bezüglich der Neigung.On its top is the fastening device 5 with a horizontal one Support surface 5c provided, on which a mounted on the connecting plate 9 Projection 9a can be placed. This gives a positive fit Transfer of the vertical shear forces. It also allows this Arrangement to level the connecting plate 9 in height by between the bearing surface 5c and the projection 9a spacer 23 placed become. Depending on the desired level of height leveling it is recommended that the through openings in the connection plate 9 for to design the reinforcement bars as elongated holes. You get one optimal adjustability of the projecting outer part, and not only horizontally and vertically, but also in terms of inclination.

Die Querkraftstäbe 4 sind, wie vor allem aus Figur 5 deutlich wird, so angeordnet, daß sie sich von der Gebäudeseite zum vorkragenden Außenteil hin einander annähern. Sie sind jedoch an ihren unteren Enden nicht mehr in die Horizontale zurückgebogen, sondern laufen direkt schräg auf die Befesigungsvorrichtung 5 zu. Damit trotzdem eine fertigungstechnisch und statisch optimale Schweißverbindung erzeugt werden kann, weist die Befestigungsvorrichtung 5 zwei schräg nach oben laufende Stümpfe 5b auf, die so geformt und positioniert sind, daß sie mit den Enden der schräg nach unten laufenden Querkraftstäbe 4 korrespondieren, so daß die beiderseitigen Stoßflächen bündig zusammenlaufen und dort verschweißt werden können, insbesondere durch Abbrennstumpfschweißung. Diese Stümpfe können dadurch erzeugt werden, daß die Befestigungsvorrichtung 5 ein Gesenkschmiedeteil ist oder indem sie an der Gegenseite der Stümpfe lokal gestaucht wird, wobei die Stauchwerkzeuge schräg einwirken.The transverse force bars 4 are, as is particularly clear from FIG. 5, arranged in such a way that that it extends from the building side to the projecting outer part towards each other. However, they are no longer at their lower ends bent back into the horizontal, but run diagonally on the Fastening device 5 to. So still a manufacturing technology and statically optimal weld connection can be generated, the fastening device 5 two stumps 5b running diagonally upwards, the are shaped and positioned so that they are slanted with the ends of the below transverse shear bars 4 correspond so that the two sides Join the butt surfaces flush and weld them there can, especially by flash butt welding. These stumps can be generated in that the fastening device 5 a Drop forging is local or by being on the opposite side of the dies is compressed, with the upsetting tools acting obliquely.
