Leichtbau-Verbunddecke *Lightweight composite floor *

Vorliegende Erfindung betrifft eine leichtbau-Verbunddecke mit auf Stahlträgern aufliegenden, durch Bolzen und Anker in schubfestern Verbund mit den Stahlträgern befindlichen Betonplatten, bei welcher zwischen den Stahlträgern und den Betonplatten erstere teilweise berührende Schalungsbleche angeordnet sind und die stumpf aufgeschweißten Bolzen eine durchgehende Schweißverbindung bis zu den Obergurten der unterhalb der Schalungsbleche liegenden Stahlträger herstellen.The present invention relates to a lightweight composite floor with resting on steel girders, through bolts and anchors in shear-resistant connection with the Steel girders located concrete slabs, in which between the steel girders and the concrete slabs partially touching shuttering sheets are arranged and the butt welded bolts a Continuous welded connection up to the upper chords of the ones below the shuttering sheets Manufacture steel girders.

Insbesondere ist bei einer derartigen Anordnung bei der Verwendung einer verlorenen Stahlblechverschalung für eine schubfeste Verbindung zwischen Träger, Verschalung und Beton Sorge zu tragen. Nach einem bekannten Verfahren werden hierfür Stahlbolzen in den Stahlträger eingeschossen, die mit ihrer freien Länge in eine Ortbetonplatte eingegossen bzw, mit einer Pertigbetonplatte verbunden werden. Bei eingeschossenen Bolzen hangt die Verbundwirkung von der mehr oder mindfr großen Beibung zwiscfteü eingeschQSsene^ Bolzenends und. !Crägerobergurt bzw. ÜJrägerstegab. Zur besseren Verankerung wurde vorgeschlagen, das eingeschossene Bolzenende nach Art eines genuteten Kerbstiftes In particular, with such an arrangement, when using a permanent sheet steel cladding to ensure a shear-proof connection between girder, casing and concrete. According to a known method, steel bolts are for this purpose in the Steel girders shot in, which are cast with their free length in an in-situ concrete slab or with a Ready-mixed concrete slab to be connected. When the bolts are shot in, the bond effect depends on the more or at least two bolt ends inserted in between for great wear and. ! Cräger upper belt or ÜJrägerstegab. For better Anchoring was proposed, the inserted bolt end in the manner of a grooved grooved pin

auszubilden. Ein Unterschied in der Festigkeit des Sitzes kann sich auch insofern ergeben, als der geschossene Bolzen nicht immer durch den Obergurt hindurch genau den Steg des Trägers trifft.to train. A difference in the strength of the Seat can also result from the fact that the bolt that is shot does not always pass through the top belt hits exactly the web of the carrier.

Im Vergleich hierzu ist es der Zweok der vorliegenden Erfindung, unter Weiterentwicklung des Standes der Technik eine solche* Bolzenbefestigung zu erzielen, die außer der Befestigung der verlorenen ochalungsbleche auf dem Trägerobergurt einen einwandfreien schubfesten Verbund auf besonders wirtschaftliche und einfache Weise ermöglicht.In comparison, it is the purpose of the present Invention of achieving such a * bolt fastening by further developing the state of the art, except for the fastening of the lost formwork sheets a flawless, shear-proof bond on the upper belt strap in a particularly economical manner and easy way.

Zur Lösung dieser Aufgabe ist die Deckenkonstruktion erfindurusgemäß in der Weise ausgebildet, da3 die Schalungsbleche derart profiliert sind, da£S um den Querschnittsbereich jedes Bolzens eine zur unmittelbaren Wärmeabfüxirung aus dem Schalungsblech in den Obergurt des Stahlträgers ohne irgendwelche sonstigen Hilfsmittel ausreichende Berührungsfläche zwischen diesen Bauteilen vorhanden ist.The ceiling construction is the solution to this problem designed according to the invention in such a way that the Formwork sheets are profiled in such a way that one to the immediate around the cross-sectional area of each bolt Heat dissipation from the shuttering sheet into the Upper chord of the steel girder without any other aids sufficient contact area between these components is available.

B-evorzugt werden die Schalungsbleche trapezförmig profiliert.The shuttering sheets are preferably profiled in a trapezoidal shape.

Auf einem Obergurt X eines Stahlträgers liegen trapezförmige Sohalungsbleche 3, die mittels durchgeschweißter zylindrischer Bolzen 4 auf dem Trägerobergurt befestigt sind« Nach dem Erhärten einer, z.B. als Ortbeton aufgebrachten, Betonplatte 7 ist der erforderliche Verbund zwischen Irä;?erobergurt und Betonplatte durch die Bolzen 4 hergestellt.
