Abstract
Description
Die Erfindung betrifft ein Verbund-Bodenelement für in Modulbauweise erstellte Gebäude. Die einzelnen Module solcher Gebäude sind in Stahlskelettbauweise erstellt und zeichnen sich durch hohen werkseitigen Vorfertigungsgrad aus. Die Bodenelemente der bekannten Module bestehen üblicherweise aus einem Bodenrahmen aus gewalztem U-Profil mit mehreren im Abstand von einander in den Rahmen eingesetzten Querträgern. Der Bodenrahmen der bekannten Bodenelemente umschließt eine mineralische Dämmung. Auf die Träger des Rahmens wird eine Sperrholzbeplankung und ein ggf. schwimmender Estrich aufgebracht. Der statische Nachweis über die Tragfähigkeit des bekannten Bodenelements erfolgt ausschließlich über die Dimensionierung der Bodenquerträger. Aus diesem Grund ist erforderlich, die Stahlprofile des Bodenrahmens und der in diesen eingesetzten Querträger großzügig zu dimensionieren. Die bekannten Bodenelemente sind daher verhältnismäßig schwer und teuer.The invention relates to a composite floor element for buildings constructed in modular design. The individual modules of such buildings are created in steel skeleton construction and are characterized by high factory prefabrication. The bottom elements of the known modules usually consist of a base frame of rolled U-profile with a plurality of spaced apart from each other in the frame cross members. The floor frame of the known floor elements encloses a mineral insulation. On the support of the frame a plywood planking and a possibly floating screed is applied. The static proof of the carrying capacity of the known floor element is carried out exclusively on the dimensioning of the floor crossmember. For this reason, it is necessary to generously dimension the steel profiles of the floor frame and the cross member used in these. The known floor elements are therefore relatively heavy and expensive.
Der Bodenaufbau wird häufig erst dann eingebracht, wenn die Module zu einem Gebäude zusammengesetzt sind. Dies ist ebenfalls teuer, da hierdurch der mögliche Vorfertigungsgrad reduziert wird.The floor structure is often introduced only when the modules are assembled into a building. This is also expensive because it reduces the potential degree of prefabrication.
Der Erfindung liegt daher die Aufgabe zugrunde, ein Bodenelement für in Modulbauweise zu erstellende Gebäude zu schaffen, welches bezogen auf das Gewicht eine höhere statische Belastbarkeit als die bisher bekannten Bodenelemente aufweist. Darüber hinaus soll das Bodenelement gemäß der Erfindung sich durch einen möglichst hohen werksseitigen Vorfertigungsgrad auszeichnen.The invention is therefore an object of the invention to provide a floor element for building to be constructed in modular construction, which has a higher static load capacity than the previously known floor elements based on the weight. In addition, the floor element according to the invention should be distinguished by the highest possible factory prefabrication degree.

Aufgrund dieses neuartigen Aufbaus des Verbund-Bodenelements gemäß der Erfindung wirkt dessen gesamter Querschnitt als Verbund-Querschnitt, wobei Zugspannungen durch die unterliegenden Profile des Rahmens und der Querträger und die Druckspannungen durch die darauf aufgebrachte Betonschicht aufgefangen werden.Due to this novel structure of the composite floor element according to the invention whose entire cross-section acts as a composite cross-section, with tensile stresses are absorbed by the underlying profiles of the frame and the cross member and the compressive stresses by the concrete layer applied thereto.
Hierdurch ergibt sich ein besonders leichter, tragfähiger und stabiler Verbund, der einschließlich der aufgebrachten Betonschicht vollständig vorgefertigt sein kann.This results in a particularly lightweight, stable and stable composite, which can be completely prefabricated including the applied concrete layer.
Vorzugsweise sind der Rahmen und die Querträger als U-Profile ausgebildet.Preferably, the frame and the cross member are formed as U-profiles.
In einer anderen Ausgestaltung der Erfindung kann vorgesehen sein, dass der Rahmen aus C-Profilen zusammengesetzt ist, wohingegen die Querträger als U-, Doppel-T-, I- oder L-Profile ausgebildet sind.In another embodiment of the invention can be provided that the frame is composed of C-profiles, whereas the cross member are formed as U, double T, I or L profiles.
Die Profile des Rahmens und der Querträger können unterschiedliche Stärke bzw. ein unterschiedliches längenbezogenes Gewicht aufweisen, wobei die Stärke der Rahmenprofile größer bemessen ist als die Stärke der Profile der Querträger.The profiles of the frame and the cross member may have different thickness or a different length-related weight, the strength of the frame profiles is sized larger than the thickness of the profiles of the cross member.
Durch die erfindungsgemäße Konstruktion ist es möglich, besonders leichte Profile als Querträger einzusetzen, wodurch insgesamt das Gesamtgewicht des Bodenelements deutlich reduziert wird.Due to the construction according to the invention, it is possible to use particularly lightweight profiles as a cross member, whereby a total of the total weight of the bottom element is significantly reduced.
Zweckmäßigerweise sind die Querträger statisch als Einfeldträger ausgelegt.Conveniently, the cross member are designed statically as a single-frame carrier.

Zweckmäßig ist es, wenn die Obergurte und/oder die sich vertikal erstreckenden Profilabschnitte zumindest der Querträger mit im Abstand von einander angeordneten Lochungen, Ausstanzungen oder Prägungen versehen sind. Wenn in den Obergurten und/oder in den sich vertikal erstreckenden Profilabschnitten jeweils Ausstanzungen vorgesehen sind, können diese so ausgebildet sein, dass das ausgestanzte Material in Stanzrichtung aus der betreffenden Oberfläche des betreffenden Schenkels des Profils hervorsteht.It is expedient if the top straps and / or the vertically extending profile sections of at least the cross member are provided with spaced holes, punched holes or embossments. If punched holes are provided in each case in the upper belts and / or in the vertically extending profile sections, these can be designed such that the punched-out material protrudes in the punching direction out of the relevant surface of the relevant leg of the profile.
Bevorzugt sind die Lochungen und/oder Ausstanzungen von dem Beton der Betonschicht durchdrungen, sodass eine formschlüssige Verankerung des betreffenden Profils in dem Beton gewährleistet ist.Preferably, the perforations and / or punched holes are penetrated by the concrete of the concrete layer, so that a positive anchoring of the relevant profile is ensured in the concrete.
Als Dämmstoff kann Mineralwolle vorgesehen sein.As insulation mineral wool can be provided.
Zweckmäßigerweise ist die Dämmstoffschicht über hakenförmige Halteelemente mit der Betonschicht verklammert. Die Halteelemente können einseitig in die Betonschicht eingegossen sein.Conveniently, the insulating layer is clamped over hook-shaped holding elements with the concrete layer. The holding elements can be cast on one side in the concrete layer.
Die Betonschicht kann als Stahlfaserbeton mit dispers verteilten Stahlnadeln ausgebildet sein.The concrete layer can be designed as a steel fiber concrete with dispersed steel needles.
Zusätzlich kann von der Betonschicht eine Armierung in Form von Stahlmatten oder dergleichen aufgenommen werden. Wenn die Querträger als L-Profile mit Ausstanzungen, Abkantungen oder Schlitzen ausgebildet sind, können die Stahlmatten beispielsweise von den sich vertikal erstreckenden Schenkeln der Querträger gehalten werden.In addition, a reinforcement in the form of steel mats or the like can be received by the concrete layer. If the cross members are formed as L-profiles with cutouts, folds or slots, the steel mats can be held for example by the vertically extending legs of the cross member.

Diese Winkelprofile sind zweckmäßigerweise mit den Rahmenprofilen verschweißt. Bei dieser Variante des Bodenelements werden die Druckspannungen über die randseitig vorgesehenen Winkelprofile in die Betonschicht eingeleitet.

Es ist für den Fachmann ersichtlich, dass die Lochung nur teilweise vom Stabstahl durchsetzt sein kann, beispielsweise kann jede zweite oder dritte Lochung (9) eines Querträgers (3) von einem Stabstahl durchsetzt sein. Die Abmessungen der Lochung (9) einerseits und des Stabstahls andererseits können so gewählt sein, dass die Lochung (9) zusätzlich von Beton durchsetzt wird.From the perforation can be added to increase the composite effect, if necessary, a steel bar. By the steel bar an additional anchoring is achieved. It will be apparent to those skilled in the art that the perforation may be only partially penetrated by the bar steel, for example, every second or third perforation (9) of a cross member (3) may be penetrated by a steel bar. The dimensions of the perforation (9) on the one hand and the bar steel on the other hand can be chosen so that the perforation (9) is additionally penetrated by concrete.
Es ist für den Fachmann nachvollziehbar, dass die Abkantung (18) senkrecht zur Ebene des Verbund-Bodenelements (1) wirkende Kräfte aufnimmt und damit die Kantenpressung der Querträger (3) verringert, sodass dies insgesamt zur Vermeidung von Rissbildung im Beton beiträgt.It is comprehensible to the person skilled in the art that the fold (18) absorbs forces acting perpendicular to the plane of the composite floor element (1) and thus reduces the edge pressure of the transverse beams (3), so that this contributes overall to the prevention of cracking in the concrete.
