Für Hohlkörperdecken werden neuerdings auftriebsfreie Hohlkörper verwendet, die im Gegensatz zu vergangenen Systemen nicht gegen Auftrieb verankert werden müssen, sondern lediglich auf die Schalung oder die untere Bewehrungslage gestellt zu werden brauchen. Die Hohlkörper bestehen aus unten offenen Hohlraumbildnern, z.B. aus Rippenstreckmetall, bei denen die Luft nach oben entweichen kann.For hollow body ceilings, buoyancy-free hollow bodies have recently been used Unlike previous systems, there is no need to anchor against buoyancy but only to be placed on the formwork or the lower reinforcement layer need. The hollow bodies consist of cavities open at the bottom, e.g. out Expanded rib metal where the air can escape upwards.
Aufgabe der Erfindung ist es, für derartige auftriebsfreie Hohlkörper einen Bewehrungskorb zu schaffen, der die Anordnung der Hohlkörper in genau bestimmten Positionen sowohl in der horizontalen Ebene als auch in der Höhe gestattet und eine gleichbleibende Betonüberdeckung der Flächen- und Schubbewehrung sicherstellt.The object of the invention is to provide a reinforcement cage for such buoyancy-free hollow bodies to create the arrangement of the hollow body in precisely defined positions both in the horizontal plane as well as the height allowed and a constant Ensures concrete coverage of the area and shear reinforcement.
Diese Aufgabe wird bei dem Bewehrungskorb der eingangs genannten Art bei dem ein aus Rundstahl gebogener oberer Ring und ein entsprechender unterer Ring mittels stehender Streben koaxial im Abstand aneinander befestigt sind, dadurch gelöst, daß in den Bewehrungskorb ein unten offener, umfangsgeschlossener Behälter angeordnet ist, dessen Deckwand Entlüftungslöcher aufweist, wobei der Behälter im Bewehrungskorb wenigstens angenähert koaxial gehalten ist und die Umfangswand des Behälters von den stehenden Streben des Bewehrungskorbes wenigstens angenähert dieselben horizontalen Abstände aufweist.This task is in the reinforcement cage of the type mentioned in the one out Round steel curved upper ring and a corresponding lower ring by standing Struts are attached to each other coaxially at a distance, solved in that in the Reinforcement cage is a container that is open at the bottom and closed at the bottom, whose top wall has ventilation holes, the container in the reinforcement cage is at least approximately coaxial and the peripheral wall of the container from the standing struts of the reinforcement cage at least approximately the same horizontal Distances.
Ein derartiger Bewehrungskorb ohne darin angeordneten Behälter ist aus DE-U-8 813 325 bekannt. Dieser Bewehrungskorb wird lediglich als Abständhalter für Bewehrungsmatten von Betondecken verwendet.Such a reinforcement cage without a container arranged in it is known from DE-U-8 813 325. This reinforcement cage is only as a spacer for reinforcement mesh of concrete ceilings used.
Als vorteilhafte Ausgestaltung ist vorgesehen, daß der obere Ring mittels horizontaler Streben diagonal ausgesteift ist. As an advantageous embodiment it is provided that the upper ring by means of horizontal Struts are braced diagonally.
Der Bewehrungskorb ist vorzugsweise aus einer Anzahl von U-Bügeln zusammengesetzt, die einander in der jeweiligen Jochmitte kreuzen und gleiche Winkelabstände aufweisen und deren Schenkel die stehenden Streben darstellen.The reinforcement cage is preferably composed of a number of U-brackets, that cross each other in the respective center of the yoke and have the same angular spacing and whose legs represent the standing struts.
Ein besonders wichtiges Merkmal der Erfindung ist nun darin zu sehen, daß der Bewehrungskorb drei U-Bügel aufweist, deren sechs Schenkel im Horizontalschnitt die Eckpunkte eines Sechseckes markieren und die beiden Ringe sechseckig gebogen und an den Ecken mit den Schenkeln der U-Bügel verschweißt sind.A particularly important feature of the invention is that the Reinforcement cage has three U-brackets, the six legs of which in horizontal section Mark the corner points of a hexagon and the two rings are bent and hexagonal the corners are welded to the legs of the U-bracket.
Die Bewehrungskörbe sind vorzugsweise als Pyramidenstümpfe ausgebildet, verjüngen sich also leicht von unten nach oben, so daß sie ineinander stapelbar sind. Das gleiche gilt für die hohlraumbildenden Behälter, die im einfachsten Fall kreisrund konturiert und entsprechend konisch ausgebildet sind. In einer bevorzugten Ausführungsform sind die Behälter aber ebenfalls in Form von Sechseck-Pyramidenstümpfen ausgebildet. Die Behälter haben mindestens an der Umfangswand, vorzugsweise aber zusätzlich auch an der Deckwand Aufhängemittel, um sie an den Bewehrungskorb anhängen und koaxial positionieren zu können. Vorzugsweise bestehen die Aufhängemittel aus biegsamen Laschen, die Ösen aufweisen, um sie mit Rödeldraht am Befestigungskorb feströdeln zu können. Flexibel sollten diese Laschen deswegen sein, um die Behälter eng ineinander stapeln zu können. Die Laschen legen sich dabei an die Behälterwände an. Anstelle der Laschen können aber auch lediglich Lochpaare oder Einzellöcher vorgesehen werden, um Befestigungsringe oder -drähte am Behälter befestigen zu können.The reinforcement cages are preferably designed as truncated pyramids, taper so easily from bottom to top, so that they can be stacked one inside the other. The same goes for for the cavity-forming containers, which in the simplest case have a circular contour and are correspondingly conical. In a preferred embodiment, the However, containers also in the form of hexagonal truncated pyramids. The Containers have at least on the peripheral wall, but preferably also on the top wall suspension means to attach them to the reinforcement cage and coaxial to be able to position. The suspension means preferably consist of flexible Tabs that have eyelets so that they can be firmly tied to the fastening basket with tied wire can. These tabs should therefore be flexible so that the containers fit tightly together to be able to stack. The tabs lay against the container walls. Instead of But tabs can also be provided only pairs of holes or individual holes To be able to attach fastening rings or wires to the container.
Mit der Erfindung wird erreicht, daß die hohlraumbildenden Behälter dank der Bewehrungskörbe sehr genau positoniert werden können. Die Bewehrungskörbe dienen gleichzeitig als Abstandshalter für die oberen Bewehrungslagen. Sie sind begehbar. Schubbewehrungsbereiche lassen sich mit voller Betonummantelung der Bewehrung und ohne Veränderung der Käfighöhe sehr einfach dadurch realisieren, daß die Bewehrungskörbe ohne eingehängte Behälter verwendet werden. Die mit den erfindungsgemäßen Bewehrungskörben und den eingehängten Behältern erzielte Decke hat eine Wabenform, die minimale Wanddicken erlaubt und hinsichtlich der Beulflächen optimal ausgebildet ist.With the invention it is achieved that the cavity-forming container thanks to the Reinforcement cages can be positioned very precisely. The reinforcement cages serve at the same time as a spacer for the upper reinforcement layers. They are accessible. Shear reinforcement areas can be covered with full reinforcement and concrete realize without changing the cage height very simply that the Reinforcement cages can be used without hanging containers. The one with the reinforcement cages according to the invention and the suspended ceiling achieved has a honeycomb shape, which allows minimal wall thicknesses and with regard to the dent areas is optimally trained.
Die Behälter sind an die Bewehrungskörbe sowohl horizontal als auch in der Höhe angepaßt, wobei der Behälter vom Bewehrungskorb vorzugsweise oben als auch unten überragt wird. Vorzugsweise läuft die Behälterumfangswand äquidistant zu einem, von den Schenkeln der U-Bügel ausgespannten Flächenring. Dieser Abstand beträgt etwa 2 cm, was für eine Betonüberdeckung ausreicht.The tanks are attached to the reinforcement cages both horizontally and in height adapted, the container from the reinforcement cage preferably above and below is towered over. Preferably, the peripheral wall of the container runs equidistant from one of the Legs of the U-bracket stretched surface ring. This distance is about 2 cm, which is sufficient for a concrete cover.
Gemäß einer Ausführungsform ist der untere Sechseck-Ring an den Enden der sechs Schenkel befestigt. Diese Ausführungsform eignet sich zum Aufsetzen des Bewehrungskorbes auf die untere Bewehrungslage. Mittels geeigneter Abstandshalter lassen sich die Bewehrungskörbe genau positonieren und mit Draht an den unteren Bewehrungslagen feströdeln. Eine Alternative der Erfindung sieht vor, daß die Bügelschenkel über den unteren Ring nach unten vorstehen. Es werden damit Füsse gebildet, die durch die unteren Bewehrungsmatten hindurchragen und auf der Plattenschalung aufstehen. Bei dieser Ausführung liegt eine vorteilhafte Ausgestaltung der Erfindung darin, daß bodenseitige Fixierplatten verwendet werden, die drei Löcher zum Einstecken von drei Schenkelfüssen dreier benachbarter Bewehrungskörbe aufweisen. Die Einstecklöcher bilden die Ecken eines gleichseitigen Dreiecks. Diese Fixierplatten können aus Kunststoff oder Holz hergestellt werden. Die Verankerung der Schubbewehrung ist durch die horizontale Ringbewehrung gewährleistet.In one embodiment, the lower hexagon ring is at the ends of the six Leg attached. This embodiment is suitable for putting on Reinforcement cage on the lower reinforcement layer. Using suitable spacers the reinforcement cages can be positioned exactly and wired to the lower ones Reinforcing layers of reinforcement. An alternative of the invention provides that the The stirrup legs protrude downwards over the lower ring. It becomes feet formed, which protrude through the lower reinforcement mats and on the Stand up slab formwork. In this embodiment there is an advantageous embodiment of the Invention in that bottom-side fixing plates are used, the three holes for Insert three legs of three adjacent reinforcement cages. The Insertion holes form the corners of an equilateral triangle. These fixing plates can be made of plastic or wood. The anchorage of the shear reinforcement is guaranteed by the horizontal ring reinforcement.
Es versteht sich, daß für die verschiedenen Decken bzw. Plattenstärken unterschiedliche Größen für die Bewehrungskörbe und damit auch für die eingehängten Behälter notwendig sind. Zum Beispiel ist für eine 66 cm-Betondecke ein Bewehrungskorb geeignet, dessen unterer Ring eine Diagonale von 70 cm und dessen oberer Ring eine Diagonale von etwa 60 cm aufweist, bei einem Höhenabstand der beiden Ringe von etwa 46 cm. It is understood that different for the different ceilings or panel thicknesses Sizes are required for the reinforcement cages and therefore also for the suspended containers are. For example, a reinforcement cage is suitable for a 66 cm concrete slab lower ring has a diagonal of 70 cm and its upper ring has a diagonal of about 60 cm, with a height distance of the two rings of about 46 cm.
Eine besonders günstige maschinelle Herstellungsmöglichkeit ergibt sich, wenn der Bewehrungskorb aus einer Anzahl gleichförmig vorgebogener Stahlbügel zusammengesetzt ist, vorzugsweise mit einem U-förmigen Teil, der an einem Ende des U-förmigen Teils einen freien Schenkel aufweist, dessen Achse außerhalb der Ebene des U-förmigen Teils angeordnet ist. Der Korb läßt sich somit aus einer einzigen vorgefertigten Bewehrungsform zusammensetzen.A particularly favorable mechanical manufacturing option results if the Reinforcement cage made from a number of uniformly pre-bent steel brackets is composed, preferably with a U-shaped part which at one end of the U-shaped Partially has a free leg, the axis of which is outside the plane of the U-shaped Partially arranged. The basket can thus be made from a single prefabricated Assemble reinforcement form.
Bei den oben beschriebenen Ausgestaltungen sind der Korb und der Hohlkörper durch Laschen und Drähte verbunden. Die Verbindung ist unter Umständen teuer und zeitaufwendig. Die wird mit Vorteil vermieden, wenn der Bewehrungskorb ein zentral angeordnetes Verbindungselement zur Befestigung des Behälters aufweist. Beispielsweise wird ein spezielles Stahlteil gebaut, das axial in dem oberen Bewehrungsstem eingeschweißt wird. An dem Stahlteil wird dann der Behälter aufgehängt. Die Anzahl der Befestigungspunkte ist somit drastisch verringert.In the embodiments described above, the basket and the hollow body are through Tabs and wires connected. The connection may be expensive and time-consuming. This is advantageously avoided if the reinforcement cage is central arranged connecting element for fastening the container. For example a special steel part is built that axially in the upper reinforcement is welded in. The container is then hung on the steel part. The number of Attachment points are thus drastically reduced.
Die Lage des Körpers läßt sich vorteilhaft fixieren, wenn der Bewehrungskorb Distanzstücke zur Lagefixierung des Behälters aufweist. Als Distanzstück kann auch eine Platte auf dem zentralen Verbindungselement dienen.The position of the body can be advantageously fixed when the reinforcement cage Has spacers for fixing the position of the container. A spacer can also be a Serve plate on the central connector.
Die Montagezeit läßt sich in einer Ausgestaltung weiter vorteilhaft verringern bei der das Verbindungselement einen Hintergriff aufweist, der mit einer zentralen Öffnung des Behälters in Verriegelnde Position bringbar ist.The assembly time can be further advantageously reduced in an embodiment in which the Connecting element has a rear grip, which with a central opening of the Container can be brought into the locking position.
Das Verbindungselement besteht beispielsweise von unten nach oben aus einer dreieckig geformten Schneide, einer Distanzplatte und einem Stück Bewehrungsstab. Distanzplatte und Schneide erhalten einen Abstand so, daß die Bodendicke dazwischen Platz findet.The connecting element consists, for example, of a triangular bottom-up shaped cutting edge, a spacer plate and a piece of reinforcing bar. spacer plate and the cutting edge are spaced so that there is space for the base thickness in between.
Zur Montage des Behälters im Bewehrungskorb wird der Korb auf der Baustelle auf den Kopf gestellt. Der Behälter wird nun mit seiner Öffnung nach oben zentrisch in die Schneide gedrückt. Der Kunststoffboden des Behälters erhält nun einen Schnitt und dringt bis zur Distanzscheibe ein. Durch Drehen des Hohlkörpers wird der Hohlkörper dauerhaft in seiner vertikalen und zentrischen Lage fixiert.To assemble the container in the reinforcement cage, the cage is placed on the construction site Upside down. The container is now centered in the opening Cutting edge pressed. The plastic bottom of the container is now cut and penetrates up to the spacer. By turning the hollow body, the hollow body becomes permanently in fixed in its vertical and central position.
Gemäß einer besonders vorteilhaften Ausführungsform ist das Verbindungselement aufsteckbar ausgebildet. Die Montagezeit wird hierdurch noch weiter verkürzt.According to a particularly advantageous embodiment, the connecting element designed to be attachable. This shortens the assembly time even further.
Zur Montage des Behälters im Bewehrungskorb wird der Korb auf der Baustelle auf den Kopf gestellt. Das obere Ende eines austeckbaren Verbindungselements ist klammerförmig ausgebildet. Mit diesem Ende wird das Verbindungselement am Bewehrungskorb durch einfaches Aufstecken auf ein Joch befestigt. Ein Anschlag verhindert ein Umkippen des Verbindungselements. Der Hintergriff des Verbindungselements, der ein Durchrutschen des Behälters verhindert, besteht beispielsweise aus zwei entgegensätzlich umgebogenen Laschen eines einstückig aus Blech gestanzten Zuschnitts. Das Verbindungselement kann somit kostengünstig in Massen gefertigt werden.To assemble the container in the reinforcement cage, the cage is placed on the construction site Upside down. The upper end of a plug-in connecting element is clip-shaped educated. With this end, the connecting element on the reinforcement cage is through simply attached to a yoke. A stop prevents the Connecting element. The rear grip of the fastener, which slips prevents the container, for example consists of two oppositely bent Tabs of a blank stamped in one piece from sheet metal. The connecting element can can thus be mass-produced inexpensively.
Der Behälter ist nun gelenkig fixiert. Zur starren Fixierung werden noch drei handelsübliche ringförmige Abstandhalter aus Kunststoff an drei vertikalen Bewehrungsstäben des Bewehrungskorbes angebracht, zwischen die der Hohlraumbildner in horizontaler Lage fixiert wird.The container is now articulated. For the rigid fixation, three more are commercially available ring-shaped plastic spacers on three vertical reinforcement bars of the Reinforcement cage attached, between which the cavity former in a horizontal position is fixed.
Die Verbindung könnte auch aus Loch und Schraube mit Mutter und Gegenmutter ggf. mit Unterlegscheiben oder Clipsverschluß bestehen.The connection could also consist of a hole and screw with a nut and lock nut if necessary Washers or clip lock exist.
Eine vorteilhafte Anordnung der Körbe wird in den Ansprüchen 19 bis 21 beschrieben. An advantageous arrangement of the baskets is described in claims 19 to 21.
Anhand der Zeichnung, die Ausführungsbeispiele der Erfindung darstellt, wird diese näher beschrieben.With reference to the drawing, which shows exemplary embodiments of the invention, this will be closer described.

Ein in Figur 1 gezeigter Bewehrungskorb 10 besteht aus drei U-Bügeln 12, die im
Winkelabstand von 60° zueinander angeordnet sind und deren Joche einander in der
Achse des Bewehrungskorbes 10 kreuzen und dort verschweißt sind. Die sechs Schenkel
14 der drei U-Bügel 12 definieren miteinander einen pyramidenstumpfförmigen Flächenring
mit gleichmäßigem Sechseckquerschnitt. Die U-Bügel bestehen aus gebogenem Rundstahl
und enden bei der Ausführung gemäß Figuren 1 bis 3 bodenseitig an einem unteren
Sechseckring 18, wo sie an den Ecken dieses Ringes ebenfalls verschweißt sind. Dicht
unter der Ebene der Joche 16 der U-Bügel 12 ist ein weiterer Sechseckring 20 ebenfalls
aus Rundstahl gefertigt und an den Schenkeln 14 angeschweißt. Der so hergestellte
Bewehrungskorb 10 ist stabil und begehbar. Der Umfang des oberen Ringes 20 ist etwas
geringer als derjenige des unteren Ringes 18. Entsprechend stehen die Schenkel 14 der
Bügel 12 schräg, bilden also die Seiten eines Trapezes. Bei einem horizontal stehenden
Bewehrungskorb 10 bilden die Schenkel 14 mit der Lotrechten einen Winkel von etwa 10°.A
In den Bewehrungskorb 10 ist ein Behälter 22 eingehängt, der unten offen ist und dessen
Deckwand 24 eine Anzahl Entlüftungsöffnungen 26 aufweist. Die Umfangswand 28 des
Behälters 22 besteht aus sechs ebenen Flächen, die äquidistant zu den von den
Bügelschenkeln 14 aufgespannten imaginären Flächen verlaufen. Der Behälter 22 stellt
also einen Pyramidenstumpf mit Sechseckquerschnitt dar. Der Behälterumfang ist etwas
kleiner als der von den Schenkeln 14 definierte Sechseckumfang, wobei der Abstand der
Behälterwände 28 von den Schenkeln 14 für eine ausreichende Betonüberdeckung der
Schenkel 14 bemessen ist und im Ausführungsbeispiel 2 oder 3 cm beträgt. Der Behälter
10 weist an der Deckwand 24 und an den Aussenkanten der Umfangswand 28
Aufhängelaschen 30 auf, mittels deren der Behälter 22 an den Jochen 16 und den
Schenkeln 14 des Bewehrungskorbes 10 befestigt, insbesondere mittels Draht angerödelt
ist.In the
Die Bewehrungskörbe 10 sind ausreichend konisch, um sie ineinanderstapeln zu können.
Das gleiche gilt für die Behälter 22, wofür jedoch die Aufhängelaschen 30 flexibel
ausgebildet sein müssen, um ein enges Ineinanderstapeln zu gewährleisten.The
Der Bewehrungskorb 10 mit eingehängtem, hohlraumbildenden Behälter 22 wird in genau
vorherbestimmter Position auf der unteren Bewehrungslage 32 aufgesetzt und festgerödelt.
Nach dem vollständigen Belegen der unteren Bewehrungslage 32 mit den
Bewehrungskörben 10 wird durch die Bewehrungskörbe 10 eine begehbare Ebene
geschaffen, auf der die obere Bewehrung 34 angeordnet wird. Die Bewehrungskörbe 10
tragen also die obere Bewehrung 34 und stellen die Abstandshalter zur unteren
Bewehrung 32 dar. Die Joche der U-Bügel der Bewehrungskörbe 10 werden ebenfalls an
der oberen Bewehrung 34 festgerödelt.The
Im Bereich hoher Schubspannungen, also insbesondere in den Unterstützungsbereichen,
werden dieselben Bewehrungskörbe 10, jedoch ohne die eingehängten Behälter 22
verwendet, wie in Figur 11 dargestellt.In the area of high shear stresses, in particular in the support areas,
are the
FIG. 4 zeigt eine Draufsicht auf eine Anordnung der Bewehrungskörbe 10 einer
herzustellenden Stahlbetondecke. Wie aus dieser Figur ersichtlich ist, werden die
Bewehrungskörbe 10 in parallelen Reihen 36, 38 angeordnet, wobei die eine Reihe zur
anderen jeweils um eine halbe Teilung versetzt ist. Jeweils drei der sechseckig konturierten
Bewehrungskörbe 10 bilden an drei benachbarten Ecken ein imagninäres gleichseitiges
Dreieck. Die in FIG. 4 nicht dargestellten, eingehängten Behälter 22 begrenzen mit ihren
Wandflächen die nach dem Einbringen des Betons entstehenden Wandstege, wodurch die
Betondecke eine Wabenstruktur erhält. FIG. FIG. 4 shows a plan view of an arrangement of the
Wie aus FIG. 2 zu ersehen ist, ist der Behälter 22 niedriger als der Bewehrungskorb 10,
wobei die Deckwand 24 des Behälters 22 im Abstand unterhalb der Joche 16 des
Bewehrungskorbes 10 angeordnet ist. Damit erhält die obere Bewehrungslage 34 eine
ausreichende Betonüberdeckung. Auch der untere Rand des Behälters 22 befindet sich im
Abstand oberhalb des unteren Ringes 18, der auf der unteren Bewehrungslage 32 aufliegt,
sodaß auch hier eine ausreichende Betonüberdeckung sichergestellt ist.As shown in FIG. 2 can be seen, the
Die Ausführung gemäß FIG. 5 bis 7 unterscheidet sich von der vorbeschriebenen
Ausführung lediglich dadurch, daß die Schenkel 14 der U-Bügel 12 des Bewehrungskorbes
10 länger ausgebildet sind und über den unteren Sechseck-Ring 18 hinausragen. Diese
Schenkelverlängerungen bilden Füsse 40 für den Bewehrungskorb 10, die zum Aufsetzen
auf der Deckenschalung bestimmt sind. Bei Sichtbetondecken können Kunststoffkappen
für die Fußenden verwendet werden. Die Ausführung gemäß FIG. 5 erlaubt dank der
vorstehenden Füsse 40 jedoch ein elegantes Positioniersystem, das anstelle einzelner
Kappen Positionierplatten beinhaltet, die je drei Löcher aufweisen, welche die Ecken eines
gleichseitigen Dreiecks bilden. Die drei benachbarten Füsse 40 von drei
aneinandergrenzenden Bewehrungskörben 10 werden dann in diese Löcher eingesteckt
und können dadurch extrem genau positioniert und deshalb auch enger aneinander
gesetzt werden, um dünne Wabenstrukturen der Hohlraumdecke zu schaffen. Die Länge
der Füsse 40 bei der Ausführung gemäß Figuren 5 bis 7 ist vorzugsweise so bemessen,
daß der untere Ring 18 des Bewehrungskorbes 10 auf der unteren Bewehrungslage 32
aufliegt oder von dieser allenfalls einen geringen Höhenabstand hat, so daß ein Feströdeln
des Bewehrungskorbes 10 an der unteren Bewehrung 32 möglich ist.The execution according to FIG. 5 to 7 differs from the one described above
Execution only in that the
Figur 8 zeigt einen Bewehrungskorb, an den ein zentral befestigtes Verbindungselement
48 befestigt ist. Dieses Verbindungselement ist axial in den oberen Bewehrungsstem 54
eingeschweißt. An diesem Verbindungselement kann nun ein Behälter 22 einfach
aufgehängt werden. An drei der sechs Schenkel sind auf mittlerer Höhe handelsübliche
Distanzstücke 50 aufgesteckt, die den Behälter in seiner Lage fixieren.Figure 8 shows a reinforcement cage to which a centrally attached connecting
In Figur 9 ist eine maschinelle Bauform des Bewehrungskorbes 10 dargestellt. Es ist
gezeigt, das der Bewehrungskorb aus sechs gleichförmig vorgebogenen Stahlbügeln 42
besteht. Der vorgebogene Stahlbügel 42 besteht aus einem U-förmigen Teilstück 44 und
einem daran angeformten Schenkel 46, dessen Achse außerhalb der imaginären Ebene
des U-förmigen Teils 44 angeordnet ist. Die vorgebogenen Stahlbügel 42 sind so
angeordnet, daß sich die Enden der angeformten Schenkel in einem Mittelpunkt treffen, wo
sie miteinander zu einem Bewehrungsstem 54 verschweißt sind. Zusätzlich sind alle
Eckpunkte eines U-förmigen Teils 44 mit den entsprechenden Eckpunkten des
angrenzenden U-förmigen Teilstücks verbunden. Der Bewehrungskorb 10 ist also aus
sechs gleichen Teilen einfach maschinell herstellbar. Die Struktur läßt sich aber auch in
andere Unterstrukturen auflösen.FIG. 9 shows a mechanical design of the
In Figur 10 ist das Verbindungselement 48 im Detail dargestellt. Ein Stück Bewehrungsstab
56 ist an den Mittelpunkt des Bewehrungsstems 54 angeschweißt. Am unteren Ende des
Bewehrungstabs ist eine dreieckig geformte Schneide 58 angebracht, die in einer zentralen
Öffnung des einzuhängenden Behälters 10 in Verriegelnde Position zu bringen ist.
Oberhalb der Schneide ist eine Distanzplatte 52 angebracht. Der Abstand zwischen
Schneide 58 und Distanzplatte 52 ist so gewählt, daß die Deckwand 24 des Behälters 22
dazwischen Platz findet.The connecting
Figur 11 zeigt eine Wabenplatte, die aus Bewehrungskörben 10 und Behältern 22
aufgebaut ist. Es ist deutlich zu erkennen, daß im Bereichen hoher Schubspannung, also
rund um die Stützpfeiler, Bewehrungskörbe ohne Behältereinsatz zur Anwendung
kommen. FIG. 11 shows a honeycomb panel consisting of
Figur 12 zeigt eine besonders vorteilhafte, alternative Ausführungsform des Verbindungselementes
62. Der Hintergriff 52 besteht aus zwei entgegensätzlich umgebogenen Laschen
eines einstückig aus Blech gestanzten Zuschnitts. Das obere Ende 64 des aufsteckbaren
Verbindungselements 62 ist klammerförmig ausgebildet. Mit diesem Ende 64 wird das
Verbindungselement 62 am Bewehrungskorb 10 durch Aufstecken auf ein Joch 16
befestigt. Ein Anschlag 66, der sich bei Bedarf auf ein Joch 16 abstützt, verhindert ein
Umkippen des Verbindungselements 62.Figure 12 shows a particularly advantageous, alternative embodiment of the connecting
Die Figuren 13 und 14 zeigen klapprichtige Darstellungen dieser vorteilhaften
Ausführungsform des Verbindungselements 62. In Figur 13 ist besonders die
klammerförmige Ausbildung des oberen Endes 64 des Verbindungselements 62 zu
erkennen. Aus Figur 14 sind besonders gut die Lage der Halterung 66 und der Hintergriff
52 ersichtlich. FIGS. 13 and 14 show correct representations of this advantageous
