Abstract

The prefabricated ceiling element, for construction of storey ceilings, comprises an elongated bearing slab, with ends to be laid on wall supports. It has two or more ribs pointing towards the support, with their ends, incorporating a reinforcement, bonded into an under-slab, with hollow spaces formed between the ribs; holes for casting in concrete are provided in the bearing slabs, leading to these hollow spaces. The ribs' reinforcement may be tied in with that of the under-slab, the outer surface of which may be of smooth facing concrete. No under-plastering is needed after installation, weight is conducive to easy transport, and the element can serve as formwork for casting the concrete ceiling, with no further support needed on the building site.

Description

Vorgefertigtes Deckenbauelement Die Erfindung betrifft ein vorgefertigtes Deckenbauelement zur Erstellung von Geschoßdecken, bestehend aus einer langgestreckten, mit ihren Enden auf Wandauflagen aufzulegenden Trägerplatte mit Versteifungsrippen. Prefabricated ceiling component The invention relates to a prefabricated Ceiling construction element for the creation of storey ceilings, consisting of an elongated, Carrier plate with stiffening ribs to be placed with their ends on wall supports.

Vorgefertigte Deckenbauelemente sind allgemein bekannt und mit den verschiedensten Querschnittformen im Handel, wobei man zwischen Elementen in Platten- und Trägerform unterscheidet. Die Elemente in Trägerform haben in der Regel einen T-förmigen Querschnitt mit in Einbaulage nach oben zu richtender Rippe. Der bei solchen Elementen nach Montage entstehende Zwischenraum wird entweder nach Einlage einer Armierung ausgegossen oder mit entsprechend angepaßten Profilsteinen ausgefüllt.Prefabricated ceiling components are well known and with the various cross-sectional shapes in the trade, where one can choose between elements in plate and carrier shape is different. The elements in support form usually have a T-shaped cross-section with a rib pointing upwards in the installation position. The at such elements after assembly resulting space is either after insert a reinforcement poured out or filled with appropriately adapted profile stones.

Plattenförmige Elemente haben in der Regel nach unten zu richtende Rippen, wobei nach Auflage der Raum zwischen den Rippen offen bleibt und später unter Verwendung von Verputzhaltegeflechten von unten her verputzt werden muß. Da der von vorneherein vorgesehene Querschnitt solcher Platten einerseits den Festigkeitsanforderungen genügen, andererseits gewichtmäßig den Transport- und Montagemöglichkeiten Rechnung getragen sein muß, ist die für die Vorfertigung zulässige Größe solcher Platten beschränkt.Plate-shaped elements usually have to be directed downwards Ribs, the space between the ribs remains open after placement and later plastered from below using plaster braids got to. Since the from the outset provided cross-section of such plates on the one hand the Sufficient strength requirements, on the other hand, in terms of weight, the transport and assembly options Must be taken into account, the size permissible for prefabrication is such Plates limited.

Der Erfindung liegt die Aufgabe zugrunde ein vorfertigbares Deckenbauelement in Plattenform zu schaffen, das nach Montage keines Unterputzes mehr bedarf und daß bei günstigem Transportgewicht nach Montage die Möglichkeit bietet, in Eigenfunktion als Schalung für den Ausguß zur Vollbetondecke zu dienen, und das auch auf der Baustelle keiner Unterstützung mehr bedarf.The invention is based on the object of a prefabricated ceiling component to create in the form of a plate that no longer requires flush mounting after installation and that with a favorable transport weight after assembly offers the possibility of self-function to serve as formwork for the sink to the solid concrete ceiling, and that also on the construction site no more support is required.

Diese Aufgabe ist mit einem Deckenbauelement der genannten Art nach der Erfindung dadurch gelöst, daß die Trägerplatte mit mindestens zwei zur Auflage hin weisenden Rippen versehen ist, die mit ihren Enden unter Einschluß einer Armierung und unter Ausbildung von Hohlräumen zwischen den Rippen in eine Unterplatte eingebunden sind, wobei in der Trägerplatte zu den Hohlräumen führende Eingreiföffnungen angeordnet sind.This task is with a ceiling element of the type mentioned the invention achieved in that the carrier plate with at least two to support pointing out ribs is provided with their ends including a reinforcement and incorporated into a sub-plate with the formation of cavities between the ribs are, wherein in the carrier plate leading to the cavities engaging openings are arranged are.

Durch diese erfindungsgemäße Ausbildung ergibt sich eine aufgrund der Hohlform bezüglich ihres Gewichtes relativ leichtes Deckenelement.This inventive training results in a due the hollow shape relatively light ceiling element in terms of its weight.

wobei die Unterplatte einerseits eine glatte Sichtfläche bildet, die kleines Verputzes mehr bedarf und die andererseits die Schalung für den Ausguß zu einer Vollbetondecke, Weitere Einzelheiten und vo rt i lhafte Weiterbildlngen werden nachfolgend an Hand der zeichnerischen Darstellung von Ausführungsbeispielen näher erläutert.wherein the lower plate on the one hand forms a smooth visible surface that small plastering needs more and the other hand, the formwork for the sink a solid concrete ceiling, further details and preliminary training in more detail below with reference to the graphic representation of exemplary embodiments explained.

In dieser Darstellung zeigt Fig. 1 einen Schnitt durch das erfindungsgemäße Deckenbauelement; Fig. 2 in perspektivischer Ansicht das Deckenbauelement nach Fig. 1; Fig. 3 zwei benachbart angeordnete Deckenbauelemente im Schnitt und Fig. 4 im Schnitt ein auf eine Auflage einer Stützwand aufgelegtes Deckenbauelement.In this illustration, Fig. 1 shows a section through the inventive Ceiling component; FIG. 2 shows the ceiling component according to FIG. 1; FIG. 3 shows two adjacently arranged ceiling components in section and FIG. 4 in Section through a ceiling component placed on a support of a supporting wall.

In den Fig. sind bezeichnet mit 1 die Trägerplatte, mit 2 deren nach unten gerichte Rippen, mit 3 die in die Unterplatte 6 eingebundenen bzw. eingegossenen Enden der Rippen, mit 5 die Hohlräume im Bauelement, mit 6 die Unterplatte, mit 7 Eingußöffnungen in der Trägerplatte, mit 4 bzw. 8 Armierungen in der Träger- und Unterplatte 1 bzw. 6, mit 9 die im Bereich der Kanalprofile lo offenen Enden der Hohlräume, mit 11 die sichtseitige Fläche der Unterplatte und mit 12 die mit einer vorspringenden Stoßkante 13 versehenen Längskanten.In the figures, 1 denotes the carrier plate, 2 their after Ribs facing downwards, with 3 those integrated or cast into the lower plate 6 Ends of the ribs, with 5 the cavities in the component, with 6 the lower plate, with 7 pouring openings in the carrier plate, with 4 or 8 reinforcements in the carrier and Lower plate 1 or 6, with 9 in the area of the channel profiles lo open ends of the Cavities, with 11 the visible surface of the lower plate and with 12 with a protruding edge 13 provided longitudinal edges.

Bei der Herstellung eines solchen Deckenbauelementes wird so vorgegangen, daß zunächst die Unterplatte unter Einschluß der Armierung 8 gegossen wird. Danach wird der ganze Korb der Armierung 4, an dem vorteilhaft auch gleich die Kanalprofile 10 befestigt sind auf den noch weichen Beton der Unterplatte 6 aufgesetzt bzw. eingedrückt und zwar soweit, daß die Unterkanten der Kanalprofile 10 au£ dem waagerechten Zug der Armierung 8 der Unterplatte aufsitzen.In the production of such a ceiling element, the procedure is as follows: that first the lower plate including the reinforcement 8 is poured. Thereafter becomes the whole basket of the reinforcement 4, on which the channel profiles are also advantageous 10 are attached to the still soft concrete of the lower plate 6 placed or pressed to the extent that the lower edges of the channel profiles 10 au £ the horizontal train the reinforcement 8 of the lower plate.

Danach erfolgt der Guß der Rippen 2 und der Trägerplatte 1, wobei natürlich in den Kanalprofilen 10, die im Bauelement verbleiben, entsprechende Öffnungen und über diesen leicht entfernbare Kerne vorgesehen werden müssen. Nach Aushärtung wird das Deckenbauelement aus der Form entnommen und die Kerne werden zur Freilegung der Öffnungen 7 entfernt.The ribs 2 and the carrier plate 1 are then cast, with of course in the channel profiles 10, which remain in the component, corresponding openings and over these easily removable cores must be provided. After curing the ceiling element is removed from the mold and the cores are exposed of the openings 7 removed.

In Fig. 4 ist verdeutlicht, wie eine aus solchen Elementen erstellte Decke vergossen- wird, um eine Vollbetondecke zu erzielen.In Fig. 4 it is shown how one created from such elements Ceiling is poured in order to achieve a solid concrete ceiling.

Auf den Stützwänden 14 werden die Deckenbauelemente mit ihren offenen Enden so auf der dort vorgesehenen Auflage 15 aufgelegt, daß ein für ein Eingießen von Beton genügend großer Spalt 16 offen bleibt.Hier kann ein Ringbalken angeordnet werden. Wenn der ganze Deckenbereich mit den Deckenbauelementen ausgelegt bzw. abgedeckt ist wird Feinbeton in die Spalten 16 und die Öffnungen 7 eingegossen, wodurch sich dann nach Aushärtung eine Vollbetondecke ergibt.On the supporting walls 14, the ceiling components with their open Ends so placed on the support 15 provided there that one for pouring A sufficiently large gap 16 remains open from concrete. A ring beam can be arranged here will. When the entire ceiling area is laid out or covered with the ceiling construction elements is fine concrete is poured into the columns 16 and the openings 7, whereby then after hardening results in a solid concrete ceiling.

Die Deckenbauelemente sind vorteilhaft so ausgebildet, daß die Längskanten 12 etwa in Höhe der Mittelebene der Unterplatte 6 mit einer gegenüber den darüber liegenden Randflächen vorspringenden Stoßkante 13 versehen sind.The ceiling components are advantageously designed so that the longitudinal edges 12 approximately at the level of the central plane of the lower plate 6 with one opposite the one above lying edge surfaces protruding abutting edge 13 are provided.

Diese Ausbildung führt beim Aneinanderliegen der Bauelemente zu einer sich nahezu über die ganze Deckendicke erstrekkende ausgießbaren Fuge 17, wodurch den Schalldämmanforderungen besser entsprochen werden kann, als dies bei bisherigen vorgefertigten Deckenbauelementen dieser Art möglich ist.This training leads to one another when the components lie against one another pourable joint 17 extending almost over the entire thickness of the ceiling, whereby the sound insulation requirements can be met better than with previous ones prefabricated ceiling construction elements of this type is possible.
