Abstract

Each reinforcing component (1), typically an anchor bolt, has a component (2) securing it to a common supporting member (3), in which there are openings allowing limited movement in the member lengthwise direction. The connecting components can be permanently engaged with the member, the length of the openings in the latter being at the most equal to the maximum static movement distance of the reinforcing component. Each connecting component can have two or more distorting lugs, which can be bent from the installation position, in which they are parallel, into the working one in which they extend in opposite directions.

Description

Die Erfindung betrifft eine Vorrichtung zur verschieblichen, gruppenweisen Anordnung von Bauelementen, insbesondere von Schubbewehrungselementen, wie sie vorzugsweise gegen das Durchstanzen von Flachdecken verwendet werden.The invention relates to a device for displaceable arrangement in groups of structural elements, in particular shear reinforcement elements, as they do preferably used against punching flat ceilings.

Für die Bewehrung von Flachdecken gegen Durchstanzen sind mehrere Systeme bekannt, die überwiegend dadurch gekennzeichnet sind, daß die Bewehrungselemente starr mit einer Tragvorrichtung verbunden sind. Dies kann auf den Baustellen regelmäßig zu Schwierigkeiten führen, da die Biegebewehrung andere Abstände aufweist als die Schubbewehrungselemente und somit in Teilbereichen deren Einbau wesentlich erschwert oder gar nicht zuläßt. Selbst wenn die Abstände der Biegebewehrung und der Schubbewehrungselemente planerisch aufeinander abgestimmt werden, ist der reibungslose Einbau nur bei Schubbewehrungseinheiten möglich, die parallel zum Bewehrungsnetz einzubauen sind. In diesem Fall entsteht das aufgezeigte Problem spätestens bei den diagonal zur Biegebewehrung einzubauenden Schubbewehrungseinheiten.There are several systems for reinforcing flat slabs against punching known, which are mainly characterized in that the reinforcement elements are rigidly connected to a support device. This can happen on construction sites regularly cause difficulties because the bending reinforcement has different distances has as the shear reinforcement elements and thus their installation in some areas much more difficult or not allowed at all. Even if the distances of the bending reinforcement and the shear reinforcement elements are coordinated with one another in terms of planning smooth installation is only for shear reinforcement units possible to be installed parallel to the reinforcement network. In this case arises the problem shown at the latest when installing diagonally to the bending reinforcement Shear reinforcement units.

Erste Ansätze zur Lösung dieses ständig auftretenden Problems wurden mit WO 97/23695A, EP 0 744 508 A1 und DE 296 12 053.7U aufgezeigt. Dort sind die Bewehrungselemente zumindest in einzelnen Beispielen lösbar mit ihrer Tragvorrichtung verbunden. Entsteht bei ihrem Einbau die oben beschriebene Schwierigkeit, können bei diesen Lösungen die betroffenen Schubbewehrungselemente gelöst und an einer passenden Stelle wieder montiert werden. The first approaches to solving this constantly occurring problem have been described in WO 97 / 23695A, EP 0 744 508 A1 and DE 296 12 053.7U. There are the reinforcement elements at least in some examples releasably connected to their carrying device. created when installing the difficulty described above, can with these Solutions the affected shear reinforcement elements solved and on a suitable one Be reassembled.

Diese Ansätze weisen aber mehrere, entscheidende Nachteile auf. So stellt dasHowever, these approaches have several decisive disadvantages. So it poses

Lösen ebenso wie das abschließende Wiederbefestigen der Bewehrungselemente in jedem Fall einen zusätzlichen Aufwand dar. Bei den in DE 296 12 053.7U angebotenen Beipielen ist hierfür sogar jeweils ein spezielles, ansonsten baustellenunspezifisches Werkzeug erforderlich, das im eher rauhen Baustellenbetrieb erfahrungsgemäß häufig verlorenginge und nicht zur Verfügung stünde, wenn es gebraucht würde. Durch die vollständige Lösbarbarkeit der Bewehrungselemente besteht die Gefahr, daß sie an Stellen wieder eingebaut werden, an denen sie entweder gar nicht oder zumindest nicht mehr ausreichend für die Standsicherheit der Konstruktion wirksam sein können. Eine wirkungsvolle Kontrollmöglichkeit ist nicht gegeben. Der gravierendste Punkt ist jedoch darin zu sehen, daß aufgrund der vollständigen Lösbarbarkeit der Bewehrungselemente diese in Einzelfällen gewollt oder - z. B. beim Transport - auch ungewollt von den Bewehrungseinheiten entfernt werden.Release as well as the final reattachment of the reinforcement elements in any case represents an additional effort. In those offered in DE 296 12 053.7U Examples of this is even a special one, otherwise unspecific for the construction site Tool required, experience has shown that in the rather rough construction site operation often lost and unavailable when needed would. Due to the complete releasability of the reinforcement elements, there is Danger that they will be reinstalled in places where they are either not or at least no longer sufficient for the stability of the construction can be effective. There is no effective control option. The most serious point, however, is that due to the complete Detachability of the reinforcement elements this is wanted in individual cases or - e.g. B. during transport - also be removed from the reinforcement units unintentionally.

Somit stellen lösbar angeordnete Bewehrungen letztlich ein nicht zu verantwortendes Sicherheitsrisiko dar. Schließlich bestätigt die Tatsache, daß derartige Systeme bislang noch nicht auf dem Markt vertreten sind, die Erkenntnis, daß ihre Herstellung im Vergleich zu den übrigen bekannten Systemen zu teuer ist. Dies gilt in besonderem Maße für diejenigen Systeme, die zur Lösbarkeit Spezialwerkzeuge erfordern.Reinforcements arranged in a releasable manner ultimately represent an irresponsible one Finally, the fact that such systems are not yet on the market, realizing that their manufacture is too expensive compared to the other known systems. This applies in especially for those systems that require special tools to solve require.

Hiervon ausgehend ist es daher Aufgabe der vorliegenden Erfindung, Bauelemente gruppenweise so anzuordnen, daß sie zwar einerseits in statisch zulässiger Weise verschoben werden können, um die beim Einbau auftretenden Probleme zu umgehen, andererseits jedoch nicht gewaltfrei von der gesamten Bewehrungseinheit entfernt werden können.Proceeding from this, it is therefore an object of the present invention, components to be arranged in groups so that they are on the one hand in a statically permissible manner can be moved to avoid problems during installation, on the other hand, however, not without violence from the entire reinforcement unit can be removed.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß zunächst ein Tragsystem vorgegeben wird, in dem die Bewehrungselemente nur in einem statisch zulässigen Teilbereich verschoben werden können. Die Verschieblichkeit selbst wird gewährleistet durch Verbindungselemente, die mit den Bewehrungselementen fest verbunden sind und deren gewaltfreies Lösen von dem Tragsystem ausschließen. Gleichzeitg erlaubt ihre Formgebung innerhalb der festgelegten Grenzen ein beliebiges Verschieben der Bewehrungselemente. Bei Bedarf können die Verbindungselemente so ausgebildet werden, daß die Bewehrungselemente sogar an jeder gewünschten Stelle unverrückbar fixiert werden können.This object is achieved in that first of all a support system is specified in which the reinforcement elements only in a statically permissible Part area can be moved. The movability itself is guaranteed by connecting elements that are firmly connected to the reinforcement elements are and exclude their non-violent release from the support system. simultaneously allows any shape within the defined limits Moving the reinforcement elements. If necessary, the connecting elements be designed so that the reinforcement elements even at any desired Position can be fixed immovably.

Die Figur 1 zeigt eine Schubbewehrungseinheit, bei der beispielhaft Doppelkopfbolzen 1 mit Hilfe von Verbindungselementen 2 unlösbar, aber bereichsweise verschieblich, mit einem Tragelement 3 verbunden sind. Das Tragelement besteht in diesem Beispiel aus zwei parallel nebeneinander liegenden Längsstäben 4, deren Querschnitt rechteckig, rund oder auch beliebig geformt sein kann. Die Längsstäbe 4 werden mit Hilfe von Querstäben 5 zu einer leiterartigen Einheit verbunden. Die Lage der Querstäbe ist dabei so gewählt, daß sie gleichzeitig die statisch erforderliche Begrenzung für die Verschieblichkeit der einzelnen Bewehrungselemente gewährleisten.Figure 1 shows a shear reinforcement unit, in the example of double-headed bolts 1 cannot be detached with the help of connecting elements 2, but can be moved in some areas, are connected to a support element 3. The support element consists of this example from two parallel longitudinal bars 4, whose Cross section can be rectangular, round or any shape. The longitudinal bars 4 are connected with the help of cross bars 5 to form a ladder-like unit. The The position of the crossbars is chosen so that they are statically required at the same time Ensure limitation for the movement of the individual reinforcement elements.

Die Figur 2 zeigt die Seitenansicht der Schubbewehrungseinheit gemäß Figur 1.FIG. 2 shows the side view of the shear reinforcement unit according to FIG. 1.

Aus der Figur 3 ist ersichtlich, wie das in den Figuren 1 und 2 gezeigte Ausführungsbeispiel auf einfache Art zusammengebaut werden kann und dennoch die gewünschten Anforderung erfüllt. Auf das obere Ende der Schubbewehrungselemente wird zunächst das Verbindungselement 7 befestigt. Dieses besteht im vorliegenden Beispiel aus einem hinreichend dicken Halteblech, dessen mittlerer Teil 8 eingeschnitten und nach unten gebogen wurde. Dieser Teil des Verbindungselements bildet den Fuß, der mit dem Bewehrungselement fest verbunden wird. In der Mitte weist das Blech 7 zwei Vertiefungen 9 auf, die durch eine zentrale Aufkantung ausgesteift sind. Die daneben liegenden, seitlichen Teile 10 werden vor der Befestigung an der Schubbewehrung nach oben gebogen. Dadurch wird die effektive Breite des Halteblechs vorübergehend so weit verringert, daß es problemlos zwischen die beiden Längsstäbe der leiterartigen Tragvorrichtung eingeschoben werden kann.FIG. 3 shows how the exemplary embodiment shown in FIGS. 1 and 2 can be assembled in a simple manner and still have the desired ones Requirement fulfilled. On the top end of the shear reinforcement elements the connecting element 7 is first attached. This exists in the present Example from a sufficiently thick holding plate, the middle part 8 cut and bent down. This part of the connector forms the foot, which is firmly connected to the reinforcement element. In the In the middle, the sheet 7 has two depressions 9, which are formed by a central upturn are stiffened. The adjacent, side parts 10 are before attachment bent upwards at the shear reinforcement. This will make the effective Width of the holding plate temporarily reduced so much that it easily between the two longitudinal bars of the ladder-like support device are inserted can.

Nachdem dieser Zustand erreicht ist, werden die seitlichen Teile 10 mit maschineller Hilfe nach unten gebogen (s. gestrichelte Pfeile), bis sie - sich voneinander weg erstreckend - auf den Längsstäben 4 aufliegen. Dadurch wird sichergestellt, daß die Bewehrungselemente aufgrund der Steifigkeit des Halteblechs verriegelt sind und nicht mehr gewaltfrei gelöst werden können. Mit Hilfe einer vorübergehend eingelegten Hilfsvorrichtung 11 wird erreicht, daß die Längsstäbe des Tragelements in dieser Position nicht zwischen dem Halteblech und der Oberkante der Bewehrung eingeklemmt werden. Dies stellt sicher, daß die in bleibenden Eingriff gebrachten Bewehrungselemente beliebig zwischen den jeweils anschließenden Querstäben 5 verschoben werden können. Dies ist aus der Darstellung in der Figur 5 gut zu erkennen. Figur 6 zeigt die zugehörige Draufsicht auf das Halteblech. Die Bewehrungselemente müssen für das Verschieben weder gelöst werden noch sind für diesen Vorgang irgendwelche Werkzeuge erforderlich.After this state is reached, the side parts 10 are machined Help bent down (see dashed arrows) until they are - apart extending away - lie on the longitudinal bars 4. This ensures that the reinforcement elements locked due to the rigidity of the retaining plate are and can no longer be solved without violence. With the help of a temporary inserted auxiliary device 11 is achieved that the longitudinal rods of the support element in this position not between the retaining plate and the top edge of the reinforcement be pinched. This ensures that those brought into permanent engagement Reinforcement elements as required between the adjacent cross bars 5 can be moved. This can be clearly seen from the illustration in FIG. 5. Figure 6 shows the associated top view of the holding plate. The reinforcement elements do not have to be solved for the move and are not for this Process any tools required.

Die Lage der Querstäbe 5 ist dadurch festgelegt, daß sie den statisch zulässigen Verschiebebereich der Bewehrungselemente zuverlässig begrenzen. Zwischen den Querstäben dürfen daher die Bewehrungselemente an jeder beliebigen Stelle verbleiben. Sollte dennoch der Wunsch bestehen, sie an einer bestimmten Stelle zu fixieren, kann dies leicht erreicht werden, indem das jeweilige Bewehrungselement um maximal 90 Grad um seine Längsachse gedreht wird. Wie aus Figur 7 ersichtlich, laufen dann die Vertiefungen im mittleren Blechbereich, die durch die zentrale Aufkantung ausgesteift sind, so weit auf die Längsstäbe der Tragvorrichtung auf, bis sie klemmen und sich nicht mehr ohne äußere Einwirkung verschieben. Figur 8 zeigt diese Position des Halteblechs in der Draufsicht. Die Verschieblichkeit kann natürlich leicht wieder hergestellt werden, indem das Bewehrungselement ein weiteres Mal um 90 Grad verdreht wird.The position of the cross bars 5 is determined by the fact that they are statically permissible Reliably limit the displacement range of the reinforcement elements. Between The reinforcement elements may therefore remain at any point in the cross bars. Should there still be a desire to place them at a certain point fix, this can be easily achieved by the respective reinforcement element is rotated by a maximum of 90 degrees around its longitudinal axis. As can be seen from Figure 7, then the depressions in the middle sheet metal area run through the central one Upstand are braced so far on the longitudinal bars of the support device, until they jam and no longer move without external influence. Figure 8 shows this position of the holding plate in plan view. The movability can of course, can easily be restored by adding another piece of reinforcement Is rotated 90 degrees.

Die Figur 9 zeigt eine weitere Ausführungsform der erfindungsgemäßen Vorrichtung.FIG. 9 shows a further embodiment of the device according to the invention.

In diesem Beispiel besteht das Tragelement 12 aus einem dicken Blech, in das Langlöcher 13 und weitere kreisförmige Öffnungen 14 gestanzt wurden. Die Lage und Größe der Langlöcher bestimmen sich nach den Bedingungen für den Einbau der Bewehrungselemente. Ihr Mittelpunkt entspricht der Sollage der Bewehrung. Ihre Länge ergibt sich aus dem zulässigen Verschiebemaß der Bewehrungselemente. Ihre Breite muß schließlich genügend Platz für das Verbindungselement gewährleisten. Die Öffnungen 14 bieten zusätzlich zu den Langlöchern 13 Möglichkeiten für die Befestigung der Bewehrungseinheit mit der Biegebewehrung. Sie sorgen zusätzlich dafür, daß sich unter dem Blechträger beim Betonieren keine schädlichen Luftblasen bilden. Schließlich können sie dazu verwendet werden, daß Elemente zur Lagesicherung durch die Öffnungen gesteckt und somit äußerst einfach montiert werden können.In this example, the support element 12 consists of a thick sheet of metal into which Elongated holes 13 and further circular openings 14 were punched. The location and size of the elongated holes are determined by the conditions for installation of the reinforcement elements. Its center corresponds to the target position of the reinforcement. Their length results from the permissible displacement dimension of the reinforcement elements. Finally, their width must ensure sufficient space for the connecting element. The openings 14 offer 13 options in addition to the elongated holes for fastening the reinforcement unit with the bending reinforcement. You worry in addition to ensuring that no harmful damage occurs under the sheet metal support when concreting Form air bubbles. Finally, they can be used to make items inserted through the openings to secure the position and thus extremely simple can be assembled.

Diese Lösung stellt eine sehr wirtschaftliche Variante dar, da hiermit die Randbedingungen für die begrenzte Verschieblichkeit mit geringstem Aufwand hergestellt werden können.This solution represents a very economical variant, since it means the boundary conditions for the limited mobility with the least effort can be.

Als Schubbewehrung sind auch in der Figur 9 beispielhaft Doppelkopfbolzen 1 dargestellt. Sie sind nun mit einem der Situation angepaßten Verbindungselement 15 ausgestattet. In der Figur 10 ist die Situation des Zusammenbaus der Bewehrungselemente 1 mit dem Tragelement 12 dargestellt.Double-headed bolts 1 are also shown by way of example in FIG. 9 as shear reinforcement. You are now with a connecting element 15 adapted to the situation fitted. In Figure 10 is the situation of the assembly of the reinforcement elements 1 shown with the support member 12.

Als kostengünstige Lösung ist auch in diesem Beispiel anstelle einer massiven Konstruktion für das Verbindungselement 15 ein ausreichend dickes Blech vorgesehen. Dessen Schnittform ist in der Figur 11 dargestellt. Sie wurde so gewählt, daß beim Ausstanzen aus einem längeren Blechband nahezu kein Verschnitt entsteht. Die im mittleren Bereich gewählte Form bietet wiederum die Möglichkeit, die Bewehrungselemente zu arretieren, falls dies gewünscht wird. Die mittig angeordnete Öffnung 16 des Halteblechs bietet die einfache Möglichkeit, das Halteblech mit dem Bewehrungselement mit Hilfe eines einzigen Schweißpunkts kraftschlüssig zu verbinden. Die gestrichelten Linien 17 geben den Verlauf der erforderlichen Blechkantungen an.In this example, too, a cost-effective solution is instead of a solid construction a sufficiently thick sheet is provided for the connecting element 15. Its sectional shape is shown in FIG. 11. It was chosen so that the Punching out of a longer sheet metal strip creates almost no waste. The in middle area selected form again offers the possibility of the reinforcement elements to lock if desired. The opening in the middle 16 of the holding plate offers the easy possibility of holding the holding plate with the reinforcement element to connect with a single weld spot. The dashed lines 17 indicate the course of the required sheet metal bends on.

Vor dem Zusammenbau sind die Kanten 17 a herzustellen. Das Halteblech bekommt dadurch in der Seitenansicht die in der Figur 10 dargestellte U-Form 15 a. Die Breite des Verbindungselements in diesem Zustand bestimmt die erforderliche Breite der Langlöcher 13 des Trägerblechs 12. Wie in der Figur 10 dargestellt, wird das Verbindungselement in das Langloch 13 eingeführt, bis die Oberkante des Bewehrungselements am Trägerblech anliegt. Dann wird das Halteblech entlang der Kantungslinien 17 b zur Verriegelung mit maschineller Hilfe nach außen gebogen, bis es die in der Figur 12 dargestellte Form 15 b einnimmt, bei der sich die beiden Flügel etwas versetzt voneinander weg erstrecken. Sie wird mit entsprechenden Hilfsmitteln auch hier so gewählt, daß die Tragvorrichtung 12 nicht zwischen Bewehrungselement 1 und Halteblech 15 b eingeklemmt wird, sondern vielmehr bei bleibendem Eingriff eine reibungsfreie Verschieblichkeit auf die gesamte Länge der Langlöcher gewährleistet ist. Für das Verschieben müssen die Bewehrungselemente weder gelöst werden noch sind für diesen Vorgang irgendwelche Werkzeuge erforderlich.Before assembly, the edges 17 a are to be produced. The holding plate gets thereby the side view of the U-shape 15 a shown in Figure 10. The width of the connecting element in this state determines the required Width of the elongated holes 13 of the carrier plate 12. As shown in FIG the connecting element is inserted into the slot 13 until the upper edge of the reinforcing element rests on the carrier plate. Then the holding plate is along the Bending lines 17 b bent outwards for locking with mechanical help, until it assumes the shape 15 b shown in FIG. 12, in which the two Extend wings slightly offset from each other. You will with appropriate Tools also chosen here so that the support device 12 is not between the reinforcement element 1 and retaining plate 15 b is clamped, but rather at permanent engagement a smooth movement along the entire length of the Elongated holes is guaranteed. The reinforcement elements have to be moved there are no tools to solve this problem required.

Auch bei diesem Ausführungsbeispiel kann das Bewehrungselement auf Wunsch an einer bestimmten Stelle mit geringstem Aufwand arretiert werden. Es muß nur wieder das Bewehrungselement um seine Achse gedreht werden - in der Darstellung der Figur 9 im Uhrzeigersinn. Nach einem Drehwinkel von weniger als 45 Grad verklemmen die ausgerundeten Teile 18 des Halteblechs mit den Wandungen des Trägerblechs. In der Figur 13 ist diese Position in der Draufsicht dargestellt. Wie im vorherigen Beispiel können sie auch hier wieder durch Zurückdrehen in den Ausgangszustand verschieblich gemacht werden.In this embodiment, too, the reinforcement element can be attached if desired can be locked in place with minimal effort. It just has to go again the reinforcement element can be rotated around its axis - in the illustration 9 clockwise. Jam after a rotation angle of less than 45 degrees the rounded parts 18 of the holding plate with the walls of the carrier plate. This position is shown in plan view in FIG. Like in You can also use the previous example by turning back to the initial state be made movable.

Eine Variante zu den hier aufgezeigten Möglichkeiten der Arretierung besteht darin, die Haltebleche jeweils soweit auf die Tragvorrichtung zu biegen, daß sie beim Verschieben einen Reibungswiderstand erzeugen. Dadurch sind sie ständig arretiert. Wenn sie bei dieser Ausführungsvariante verschoben werden sollen, ist dies durch leichte Hammerschläge gegen das Kopfende der Bewehrungselemente zu erreichen.A variant of the locking options shown here is to bend the retaining plates to the extent that they move create a frictional resistance. As a result, they are constantly locked. If they are to be moved in this embodiment variant, this is done by light hammer blows against the head end of the reinforcement elements.

Die Figuren 14 bis 18 zeigen die Elemente einer weiteren Variante der erfindungsgemäßen Vorrichtung, die infolge der Einfachheit sowohl des Trägers als auch der Verbindungslemente eine ganz besonders wirtschaftliche Lösung darstellt. Abweichend von den übrigen Varianten können bei dieser Lösung die Bewehrungselemente nicht an einer bestimmten Stelle fixiert werden. Dies ist im allgemeinen aber auch nicht erforderlich, da sich die Bewehrungselemente ohnehin an jeder beliebigen Stelle innerhalb der Öffnung 13 befinden dürfen.FIGS. 14 to 18 show the elements of a further variant of the invention Device that due to the simplicity of both the wearer and the Connection elements represent a particularly economical solution. deviant The reinforcement elements of this solution can be used with this solution cannot be fixed in a specific place. In general, however, this is also not necessary, since the reinforcement elements are attached to any one anyway Location within the opening 13 may be.

Die Figur 14 zeigt zunächst die besonders einfache Schnittform eines Verbindungselements 19 aus einem Blech mit der mittig angeordneten Öffnung 20 und dem Verlauf der erforderlichen Blechkantungen 21 a und b. Alternativ zum Zusammenbau gemäß Figur 10 können die Verbindungselemente auch vorab in die endgültige Form gebogen werden und erst anschließend mit den Bewehrungselementen und dem Träger zusammengefügt werden. Die Figur 15 zeigt für diesen Fall die Seitenansicht des vorab vollständig gekanteten Verbindungselements 19.FIG. 14 first shows the particularly simple sectional shape of a connecting element 19 from a sheet with the centrally arranged opening 20 and the course the required sheet metal bends 21 a and b. As an alternative to assembly According to Figure 10, the connecting elements can also be in advance in the final Form are bent and only then with the reinforcement elements and be joined to the carrier. In this case, FIG. 15 shows the side view of the connecting element 19 which has been completely folded beforehand.

Die Bewehrungselemente 1 werden bei dieser Herstellungsvariante mit der Tragvorrichtung 22 zusammengestellt und auf die Tragvorrichtung werden jeweils über den Bewehrungselementen 1 Verbindungselemente 19 angeordnet. Mit einem Schweißpunkt in die Öffnung 20 werden die Bewehrungselemente mit Hilfe der Verbindungselemente mit der Tragvorrichtung - gewaltfrei nicht lösbar - verbunden. Die Figur 17 zeigt eine Teildraufsicht auf die zusammengefügten Elemente.The reinforcement elements 1 are in this manufacturing variant with the support device 22 compiled and on the carrying device are each over the Reinforcement elements 1 connecting elements 19 arranged. With a spot weld in the opening 20, the reinforcement elements with the help of the connecting elements connected to the carrying device - non-violently non-releasable. The figure 17 shows a partial top view of the assembled elements.

Die in der Figur 18 dargestellte Gesamtdraufsicht der erfindungsgemäßen Vorrichtung zeigt die Einfachheit und optimale Funktionalität dieser Variante. Abweichend von dem in der Figur 9 dargestellten Beispiel wurde der Blechträger 22 dergestalt leicht variiert, daß beim Abschneiden vom Coil kein rechtwinkliger, sondern ein pfeilförmiger Schnitt (23 a und 23 b) vorgesehen wird. Damit wird auf einfachste Weise erreicht, daß für die Tragvorrichtung eine eindeutige Einbaurichtung vorgegeben werden kann. Die kleinen Öffnungen 24 bieten weitere Möglichkeiten, die Vorrichtung mit der Bewehrung zu verrödeln.The overall plan view shown in FIG. 18 of the device according to the invention shows the simplicity and optimal functionality of this variant. deviant The sheet metal carrier 22 was designed in this way from the example shown in FIG slightly varies that when cutting from the coil not a right angle, but a arrow-shaped section (23 a and 23 b) is provided. This is the simplest Achieved that a clear installation direction is specified for the support device can be. The small openings 24 offer further possibilities that Fixing device with the reinforcement.
