Beispielsweise aus der DE-Al-24 36 515 ist ein Deckenträger bekannt, der aus zwei Untergurten und einem Obergurt besteht, die mittels DiagonalStäben verbunden sind. Die Ober- und Untergurte sind dabei aus Rundstahl gefertigt.For example, from DE-Al-24 36 515 a ceiling support is known which consists of two lower chords and an upper chord, which are connected by means of diagonal bars. The upper and lower belts are made of round steel.
Aus der DE-Al-23 39 638 ist eine Profilblechplatte für Verbunddecken aus Profilblechen und Beton bekannt. Sie weist ein Profilblech auf, das trapezförmig abgewinkelt ist, wobei diese trapezförmigen Abwinkelungen den eigentlichen Verbundkörper bilden. Das Profilblech ist in dem in den Beton hineinragenden Bereich (Verbundkörper) mit Stanzungen versehen.From DE-Al-23 39 638 a sheet metal plate for composite ceilings made of sheet metal and concrete is known. It has a profiled sheet which is angled in a trapezoidal shape, these trapezoidal angled portions forming the actual composite body. The profiled sheet is stamped in the area (composite body) projecting into the concrete.
Aus dem deutschen Gebrauchsmuster 9214426 ist ein Deckenträger aus Stahlblech für eine Verbunddecke bekannt, die eine untere Trägerplatte aus Stahl und einen damit verschweißten in den Ortbeton ragenden Verbundkörper aufweist. Der Verbundkörper ist im Querschnitt als dreiseitig geschlossener Stahlblechkasten ausgeführt, der zur Trägerplatte offen ist. Weiters weist 2 AT 000 678 Ul der Verbundkörper in seinem oberen Abdecksteg Öffnungen auf, die den Durchtritt von Ortbeton gestatten. Am Rande der Öffnungen ist der Verbundkörper mit nach innen abstehenden Laschen versehen, die den Verbund mit dem Ortbeton verbessern.From the German utility model 9214426 a ceiling support made of sheet steel for a composite ceiling is known, which has a lower support plate made of steel and a composite body which is welded to the in-situ concrete. The cross-section of the composite body is designed as a steel sheet box closed on three sides, which is open to the carrier plate. Furthermore, 2 AT 000 678 ul of the composite body has openings in its upper cover web which allow in-situ concrete to pass through. At the edge of the openings, the composite body is provided with tabs projecting inwards, which improve the bond with the in-situ concrete.
Aufgabe der Erfindung ist es, einen Decken- und Stahlträger zu schaffen, der wie ein herkömmlicher Träger mit Ober- und Untergurten zu verlegen ist, sich jedoch durch besonders guten Verbund mit dem Beton auszeichnet und einerseits ein gewünschtes duktiles Verhalten des Verbundquerschnitts garantiert, andererseits den konstruktiven Verbund in den Druckplattenbereich der Decke gewährleistet.The object of the invention is to provide a ceiling and steel girder, which is to be laid like a conventional girder with top and bottom chords, but is characterized by a particularly good bond with the concrete and on the one hand guarantees a desired ductile behavior of the bonded section, on the other hand it guarantees constructive bond in the pressure plate area of the ceiling guaranteed.
Die erfindungsgemäße Aufgabe wird dadurch gelöst, daß zu-mindestens ein Teil der Laschen senkrecht nach oben absteht und daß diese Laschen quer zur Längserstreckung des Deckenträgers ausgerichtet sind.The object of the invention is achieved in that at least some of the tabs protrude vertically upwards and that these tabs are aligned transversely to the longitudinal extent of the ceiling beam.
Nachfolgend werden zwei Ausführungsbeispiele der Erfindung anhand der Figuren der beiliegenden Zeichnungen beschrieben.Two exemplary embodiments of the invention are described below with reference to the figures in the accompanying drawings.
Die Fig. 1 zeigt ein Schaubild eines erfindungsgemäßen Deckenträgers und die Fig. 2 bis 4 zeigen Längsschnitte durch den oberen Abdecksteg verschiedener Ausführungsbeispiele der erfindungsgemäßen Deckenträger.1 shows a diagram of a ceiling support according to the invention and FIGS. 2 to 4 show longitudinal sections through the upper cover web of various exemplary embodiments of the ceiling supports according to the invention.
Der erfindungsgemäße Deckenträger besteht aus einer Trägerplatte 1 und einem kastenförmigen Verbundkörper 16.The ceiling support according to the invention consists of a support plate 1 and a box-shaped composite body 16.
Der Verbundkörper 16 ist mit einem oberen Abdecksteg 17 und seitlichen Stegen 171 dreiseitig geschlossen ausgebildet und weist bei der Trägerplatte 1 nach innen gewinkelte Stege 18 auf, mit denen es mit der Trägerplatte 1 verschweißt ist. 3 AT 000 678 UlThe composite body 16 is formed with an upper cover web 17 and lateral webs 171 closed on three sides and has inwardly angled webs 18 on the carrier plate 1, with which it is welded to the carrier plate 1. 3 AT 000 678 ul
Der obere Abdecksteg 17 des Verbundkörpers 16 weist viereckige ausgestanzte Löcher 13 auf, durch die der Beton in den Innenraum 14 des Deckenträgers, der von der Stahlplatte 1 und dem Verbundkörper 16 abgegrenzt wird, eindringen kann. Am Rande der Löcher 13 sind nach innen gebogene Laschen 13 vorgesehen, die den Verbund mit dem Ortbeton verbessern.The upper cover web 17 of the composite body 16 has square punched holes 13 through which the concrete can penetrate into the interior 14 of the ceiling beam, which is delimited by the steel plate 1 and the composite body 16. At the edge of the holes 13 inwardly bent tabs 13 are provided, which improve the bond with the in-situ concrete.
Weiters sind senkrecht vom Abdecksteg 17 nach oben abgewinkelte Laschen 2 vorgesehen. Die Laschen 2 bewirken eine Verdübelung des Deckenträgers mit dem Ortbeton, wodurch der Verbund zwischen dem Deckenträger und dem Ortbeton wesentlich verbessert wird.Furthermore, tabs 2 are provided which are angled vertically upward from the cover web 17. The tabs 2 cause the ceiling beam to be anchored to the in-situ concrete, which significantly improves the bond between the ceiling beam and the in-situ concrete.
Ein erfindungsgemäßer Deckenträger kann auch, wie in der Fig. 2 gezeigt, nur mit nach oben abstehenden Laschen 2 versehen sein. Auch kann die Anordnung der Laschen 2, 3 variieren. So befinden sich im Ausführungsbeispiel nach der Fig. 3 bei jedem Loch 13 entweder nach oben abgewinkelte Laschen 2 oder nach unten abgewinkelte Laschen 3. Im Ausführungsbeispiel nach der Fig. 4 ist jedes zweite Loch 13 an einem Rand mit einer nach oben abgewinkelten Lasche 2 und am gegenüberliegenden Rand mit einer nach unten abgewinkelten Lasche 3 versehen. Das Verhältnis von den nach oben abgebogenen Laschen 2 zu den nach unten abgebogenen Laschen 3 sowie ihre Anordnung kann den jeweiligen Anforderungen angepaßt werden.A ceiling support according to the invention can also, as shown in FIG. 2, only be provided with tabs 2 projecting upwards. The arrangement of the tabs 2, 3 can also vary. Thus, in the exemplary embodiment according to FIG. 3, each hole 13 has either upwardly angled tabs 2 or downwardly angled tabs 3. In the exemplary embodiment according to FIG. 4, every second hole 13 is at an edge with an upwardly angled tab 2 and provided on the opposite edge with a tab 3 angled downwards. The ratio of the tabs 2 bent upwards to the tabs 3 bent downward and their arrangement can be adapted to the respective requirements.
Alle Laschen 2, 3 sind quer zur Längsausrichtung des Deckenträgers angeordnet.All tabs 2, 3 are arranged transversely to the longitudinal orientation of the ceiling girder.
In den Seitenstegen 17' des Profileisens 16 befinden sich dreiecksförmige Löcher 19, deren Zwischenstreben 20 ein Fachwerk bilden. 4 AT 000 678 UlIn the side webs 17 'of the profile iron 16 there are triangular holes 19, the intermediate struts 20 of which form a framework. 4 AT 000 678 Ul
Bei einem Ausführungsbeispiel der Erfindung ist vorgesehen, daß die Trägerplatte, der obere Abdecksteg und die seitlichen Stege als separate Teile zum endgültigen Trägergebilde zusammengeschweißt sind. Diese Konstruktion hat den Vorteil, daß entsprechend den statischen, konstruktiven und produktionsbedingten, (z. B. Verformung) differenzierten Anforderungen an die einzelnen Platten auch unterschiedliche Qualitäten eingesetzt werden können. Damit kann die Wirtschaftlichkeit wesentlich verbessert werden. 5In one embodiment of the invention it is provided that the carrier plate, the upper cover web and the side webs are welded together as separate parts to form the final carrier structure. This construction has the advantage that different qualities can be used for the individual panels in accordance with the static, constructive and production-related (e.g. deformation) differentiated requirements. This can significantly improve economy. 5
