Description
Die Erfindung betrifft eine gitterträgerfreie Deckenkonstruktion, insbesondere eine großflächige Schalungskonstruktion für Stahlbetondecken, mit einer Mehrzahl von Deckenelementen, sowie ein Deckenelement für eine solche Deckenkonstruktion.The invention relates to a lattice girder-free Ceiling construction, especially a large one Formwork construction for reinforced concrete slabs, with a plurality of ceiling elements, as well as a ceiling element for such Ceiling construction.
Es sind Verbundschalungsdecken nach EP-A-0 164 330 bekannt, welche aus tragenden Stahlgitterträgern mit daran mittels Verbindungsteilen befestigten Schalungsplatten bestehen, welche gleichzeitig die spätere Deckenoberflächen darstellen. Bei einer vergleichbaren Verbundschalung nach DE-A-4341856 weisen die Gitterträger zwei Untergurtstäbe und einen Obergurtstab auf. Die im Abstand von der zugeordneten Schalungsplatte verlaufenden beiden Untergurtstäbe werden von in Reihe miteinander fluchtenden U-förmigen Bügeln klemmend übergriffen, die mit ihren abgewinkelten Flanschabschnitten jeweils mit der zugeordneten Schalungsplatte verschraubt sind. Bei beiden dieser Ausführungsformen mit Gitterträgern übernimmt beim Einsatz der Verbundschalung als Deckenkonstruktion der Obergurt des Stahlgitterträgers die Druckkräfte, welche im Montagezustand und während des Betonierens sowie des Aushärtens des Betons auftreten. Nach dem Aushärten des Betons ist dieser Obergurt samt den schrägen Verbindungsstäben des Stahlgitterträgers in der Feldbewehrung der Decke statisch überflüssig.Composite formwork ceilings according to EP-A-0 164 330 are known, which are made of load-bearing steel lattice girders Connection parts attached formwork panels, which simultaneously represent the later ceiling surfaces. at have a comparable composite formwork according to DE-A-4341856 the lattice girder two lower chord bars and one upper chord bar on. The at a distance from the assigned formwork panel Trending two lower chord bars are in line mutually aligned U-shaped brackets, which with their angled flange sections each with the assigned formwork panel are screwed. By both of these embodiments with lattice girders Use of composite formwork as a ceiling structure for the top chord of the steel lattice girder the compressive forces, which in Installation status and during concreting and hardening of the concrete occur. After the concrete has hardened, this is Upper chord including the oblique connecting rods of the Steel lattice girder static in the field reinforcement of the ceiling superfluous.
Derartige herkömmliche Verbundkonstruktionen nehmen einen erheblichen Raum ein, so daß sie nur mit großem Aufwand als vorgefertigte Bauelemente transportiert werden können. Ihr Aufbau ist außerdem mit hohem Fertigungsaufwand verbunden und eher kostspielig.Such conventional composite structures take up a significant amount of space a, so that it is only with great effort as a prefabricated Components can be transported. Your structure is also associated with high manufacturing costs and rather expensive.
Mit der Erfindung wird das Problem gelöst, eine Verbundschalungsdecke sowie Deckenelemente dafür zu schaffen, deren Stahlbewehrung sowohl während der Deckenherstellung als auch bei der fertigen Decke tragende Funktionen übernehmen kann, so daß sie baustatisch anrechenbar ist, und die gleichzeitig kostengünstig herstellbar ist.With the invention the problem is solved, a To create composite formwork ceilings and ceiling elements for their steel reinforcement both during the construction of the slab and also take on supporting functions in the finished ceiling can, so that it can be credited in terms of construction, and the is inexpensive to manufacture at the same time.
Hinsichtlich der Deckenkonstruktion wird dieses Problem erfindungsgemäß gelöst mit einer Deckenkonstruktion gemäß dem Patentanspruch 1. Die gitterfreie Deckenkonstruktion, insbesondere großflächige Schalungskonstruktion für Stahlbetondecken, ist versehen mit einer Mehrzahl von Deckenelementen, die mit ihren seitlichen Stoßrändern stumpf aneinanderstoßen, wobei die Deckenelemente eine Grundplatte, auf der Grundplatte in Reihe miteinander fluchtend angeordnete U-profilförmige Bügel, die jeweils einen Steg, zwei Schenkel und an den freien Enden der Schenkel ausgebildete abgewinkelte Flanschabschnitte aufweisen, wobei die Flanschabschnitte jeweils mit der Grundplatte verschraubt sind, und Einzellängsstäbe aufweisen, die in den von den Schenkeln und den Stegen der U-profilförmigen Bügel gebildeten Ecken jeweils mit einer Schweißverbindung derart befestigt sind, daß sie einen Abstand von der Grundplatte aufweisen, so daß die Einzellängsstäbe druckübertragend sind und die Grundplatte zugübertragend ist, solange keine oder eine flüssige Betonschicht auf der Grundplatte aufliegt, d.h. die Betonschicht noch nicht tragfähig ist, und die Einzellängsstäbe zugübertragend sind, nachdem die auf der Grundplatte aufliegende Betonschicht, in die die Einzellängsstäbe eingebettet sind und von der sie um ein geeignetes Maß überdeckt sind, verfestigt und daher lastabtragend ist.With regard to the ceiling construction, this problem solved according to the invention with a ceiling construction according to the Claim 1. The grid-free ceiling construction, especially large-area formwork construction for Reinforced concrete ceilings are provided with a number of Ceiling elements that are blunt with their side edges butt together, the ceiling elements being a base plate, on the base plate in line with each other U-shaped bracket, each with a web, two legs and angled at the free ends of the legs Have flange sections, the flange sections are each screwed to the base plate, and Have individual longitudinal bars that in the of the legs and the webs of the U-shaped brackets formed corners are fastened with a welded connection such that they have a distance from the base plate so that the Individual longitudinal bars are pressure-transmitting and the base plate is train-transferring, as long as none or a liquid Concrete layer lies on the base plate, i.e. the Concrete layer is not yet load-bearing, and the individual longitudinal bars are transferring after that on the base plate overlying concrete layer, into which the individual longitudinal bars are embedded and of which they are an appropriate amount are covered, solidified and therefore load-bearing.
Die U-profilförmigen Bügel sind somit derart auf die Grundplatte gesetzt, daß ihr Steg im Abstand von der Grundplatte angeordnet ist und ihre Schenkel vom Steg zu der Grundplatte verlaufen. An den an der Grundplatte endenden freien Enden der Schenkel sind von den Schenkeln nach außen abgewinkelte Flanschabschnitte vorhanden, mit denen der U-profilförmige Bügel an der Grundplatte angeschraubt ist.The U-profile-shaped bracket are thus on the Base plate set that their web at a distance from the Base plate is arranged and its legs from the web to the Base plate run. At the ends of the base plate free ends of the thighs are outward from the thighs angled flange sections available with which the U-shaped Bracket is screwed to the base plate.
Durch den Vorschlag, bei einem Deckenelement in einem Abstand von der Grundplatte verlaufende Einzellängsstäbe derart anzubringen, daß sie bei der Montage und bis zum Aushärten des Betons als Druckstäbe und nach dem Aushärten des Betons als Zugstäbe funktionieren, wird eine doppelte Funktion der Deckenkonstruktion erreicht. Die Deckenkonstruktion kann gleichzeitig als Schalungsdecke und als tragende Bewehrung der fertigen Betondecke dienen.By proposing a ceiling element at a distance individual longitudinal rods extending from the base plate in this way to attach that they during assembly and until the hardening of the Concrete as pressure bars and after the concrete has hardened as Tension rods work will be a double function of the Ceiling construction reached. The ceiling construction can at the same time as formwork slab and as load-bearing reinforcement for the finished concrete ceiling.
Die Einzellängsstäbe befinden sich in einem ausreichenden Abstand von der Grundplatte, so daß sie die Eigenlasten der aufgebauten Deckenkonstruktion und die beim Vergießen des Betons infolge des Eigengewichts des Betons anfallenden Lasten als Druckstäbe aufnehmen. Als Zugelement in dieser tragenden Deckenkonstruktion dient die Grundplatte selbst. Die Übertragung der Scherkräfte zwischen dem Druckelement und dem Zugelement in dieser Stützkonstruktion ist durch die schubfesten Schweißverbindungen bzw. Schraubenverbindungen gewährleistet.The individual longitudinal bars are in sufficient Distance from the base plate so that it is the dead weight of the built ceiling construction and that when casting the Loads due to the weight of the concrete as pressure rods. As a tension element in this load-bearing The base plate itself serves the ceiling construction Transfer of shear forces between the pressure element and the Tension element in this support structure is due to the shear-resistant welded connections or screw connections guaranteed.
Da die Schalungsdeckenelemente der Deckenkonstruktion auf die Dicke der zu erstellenden Betondecke derart abgestimmt sind, daß die Einzellängsstäbe im unteren Bereich, insbesondere im unteren Drittel, der fertigen Betondecke zu liegen kommen, nehmen die Einzellängsstäbe im fertigen Zustand der Betondecke die Zugkräfte der Stahlbetondecke auf. Im ausgehärteten Zustand nimmt der Beton dabei die entsprechenden Druckkräfte auf.Since the formwork ceiling elements of the ceiling construction on the Thickness of the concrete slab to be created are coordinated in such a way that the individual longitudinal bars in the lower area, especially in bottom third of the finished concrete surface take the individual longitudinal bars in the finished state of the concrete ceiling the tensile forces of the reinforced concrete ceiling. In the hardened state the concrete absorbs the corresponding compressive forces.
Durch die einfache Konstruktion der Bewehrung der Grundplatte mit einfachen U-profilförmigen Bügeln, die aus abgekantetem Blech hergestellt sein können, und Schweiß- bzw. Schraubenverbindungen wird eine sehr einfache und kostengünstige Realisierung dieses doppelfunktionalen Effekts erzielt.Due to the simple construction of the reinforcement of the base plate with simple U-profile-shaped brackets made from folded Sheet can be made, and welding or Bolted connections will be a very simple and cost-effective realization of this double-functional effect achieved.
Die mit ihren seitlichen Stoßrändern stumpf aneinanderstoßenden Deckenelemente können an den Stößen mittels Leiste oder Klebeband abgedeckt sein und/oder mit Laschen verschraubt sein.Those with their side abutting edges Ceiling elements can be attached to the joints using strips or Be covered with tape and / or screwed with tabs.
Die Befestigung der Einzellängsstäbe an den U-profilförmigen Bügeln kann erfindungsgemäß durch vollständiges Verschweißen über die ganze Länge des Bügelelements erfolgen. Bevorzugt ist jedoch eine Befestigung mit einem Schweißpunkt je Verbindung zwischen einem Einzellängsstab und einem U-profilförmigen Bügel vorgesehen. Vorteilhaft kann für die Verbindung mit einem Einzellängsstab auch ein Schweißpunkt an jedem Ende des U-profilförmigen Bügels vorgesehen sein.The attachment of the individual longitudinal bars to the U-profile According to the invention, ironing can be achieved by welding completely over the entire length of the bracket element. Is preferred however, one attachment with one welding spot per connection between a single longitudinal bar and a U-shaped bracket intended.

Die U-profilförmigen Bügel können erfindungsgemäß mit beliebigen Abmessungsverhältnissen vorgesehen sein, die geeignet sind, die gewünschte Relativstellung zwischen Einzellängsstäben und Grundplatte zu ermöglichen. Dabei ist es denkbar, sehr kurze Profilelemente zu verwenden, bei denen die Stegbreite des U-profilförmigen Bügels wesentlich größer ist als die Länge des U-profilförmigen Bügels. Bevorzugt sind jedoch U-profilförmige Bügel verwendet, deren Stegbreite erheblich kürzer ist als die Länge des U-profilförmigen Bügels. Eine solche Konstruktion ermöglicht es in Verbindung mit einer geeigneten Schweißverbindung nämlich, eine besonders hohe Biegebelastung der Verbunddeckenkonstruktion zu gewährleisten.According to the invention, the U-shaped brackets can also be used any dimensional ratios may be provided are suitable, the desired relative position between To enable individual longitudinal bars and base plate. It is conceivable to use very short profile elements in which the Web width of the U-shaped bracket is significantly larger than the length of the U-shaped bracket. Are preferred however, U-profile-shaped brackets are used, the web width of which is considerably shorter than the length of the U-shaped bracket. Such a construction makes it possible in connection with a a suitable welded joint, a particularly high one To ensure bending stress of the composite ceiling construction.
