Description

Die Erfindung betrifft ein Rippendeckenelement nach dem Oberbegriff des Anspruchs 1.The invention relates to a rib ceiling element according to the preamble of claim 1.

Ein Element dieser Art ist aus der DE-PS 1 928 656 bekannt. In seinem aus Längs- und Querstreben bestehenden Gitterrost sind die Schalen mit ihren Rändern derart verankert, daß sie die Gitteröffnungen verdecken oder, anders ausgedrückt, daß die Längs- und Querstege des Gitterrostes die Verbindung zwischen den einzelnen Schalen darstellen. Zwischen den Wänden einander benachbarter Schalen verbleiben über den Streben tiefe Rinnen, die sich nach oben, also zu den Schalenböden hin, konisch verbreitern, da die Schalenwände geneigt sind. Diese Rinnen werden beim Aufbringen der Ortbetonschicht mit ausgefüllt. Die Ortbetonschicht muß aus statischen Gründen über den Schalenböden mindestens 3 cm dick sein. Die bekannten Elemente sind leicht und mit normalen Hebezeugen an die Verlegungsstelle zu bringen. Sie erfordern dort jedoch bis zum Abbinden des aufzubringenden Ortbetons Absetzungen in relativ kleinen Abständen. Bei der Herstellung der Elemente ist außerdem eine relativ aufwendige Schalung erforderlich, um die Zwischenräume zwischen den Schalenwänden in deren Randbereich überall gleichmäßig auszugießen, d.h. den Gitterrost kontinuierlich und in durchgehend gleicher Höhe auszubilden.An element of this type is known from DE-PS 1 928 656. In its grating consisting of longitudinal and transverse struts, the shells are anchored with their edges in such a way that they cover the grating openings or, in other words, that the longitudinal and transverse webs of the grating represent the connection between the individual shells. Deep channels remain above the struts between the walls of mutually adjacent shells, which widen conically upwards, that is to say towards the bottom of the shells, since the shell walls are inclined. These channels are also filled in when the in-situ concrete layer is applied. For static reasons, the in-situ concrete layer must be at least 3 cm thick above the shell bottoms. The known elements are light and can be brought to the installation site with normal lifting equipment. However, they require settling at relatively short intervals until the in-situ concrete to be applied sets. In the manufacture of the elements, a relatively complex formwork is also required in order to evenly pour out the spaces between the shell walls in their edge area, i.e. to form the grating continuously and at the same height throughout.

Aufgabe der Erfindung ist es, ein Rippenelement der eingangs beschriebenen Art so auszubilden, daß es auf wirtschaftliche Weise herstell- und an der Verlegungsstelle anbringbar ist.The object of the invention is to design a rib element of the type described at the outset in such a way that it can be produced economically and can be attached to the installation site.

Die Aufgabe wird erfindungsgemäß nach dem Merkmal des Anspruchs 1 gelöst.The object is achieved according to the feature of claim 1.

Das Ausfüllen der Zwischenräume zwischen den Schalen bis zu deren Oberseitenfläche ermöglicht die Verwendung einer einfachen Schalung. Das Element ist somit wirtschaftlicher und einfacher herstellbar. Ferner erhöht sich seine Eigenstabilität wesentlich: Die Dicke der Schalenwände addiert sich für die Festigkeitsberechnung zu der Breite des dazwischen angegossenen Steges. Die erheblich vergrößerte Eigensteifigkeit der Elemente erlaubt beim Verlegen unterstützungsfreie Bereiche, die ein Mehrfaches der vorher möglichen Abstände zwischen Unterstützungen betragen. Damit wird ein rascheres und wirtschaftlicheres Verlegen möglich. Ferner ist der Raum unter dem Element besser zugänglich.Filling the spaces between the shells up to their top surface enables the use of simple formwork. The element is therefore more economical and easier to manufacture. Furthermore, its inherent stability increases significantly: the thickness of the shell walls is added to the width of the web cast in between for the strength calculation. The significantly increased inherent rigidity of the elements allows support-free areas when laying, which are a multiple of the previously possible distances between supports. This enables faster and more economical laying. Furthermore, the space under the element is more accessible.

Als vorteilhaft hat sich eine Höhe der Schalen von 16 bis 18 cm erwiesen.A height of the shells of 16 to 18 cm has proven to be advantageous.

Vorteilhafterweise weisen die Schalen eine Dicke von 2 cm auf. Damit ist die Oberseite der Schalen im Bedarfsfall begehbar.The shells advantageously have a thickness of 2 cm. This means that the top of the trays can be walked on if necessary.

Zusätzlich kann an den Gitterrost eine faserbewehrte Untersichtsplatte angegossen sein. Der Gitterrost kann an seiner Unterseite aufgerauht sein, wodurch die Verbindung mit der Untersichtsplatte noch inniger wird.In addition, a fiber-reinforced base plate can be cast onto the grating. The grating can be roughened on its underside, which makes the connection with the base plate even more intimate.

Für eine Decke aus erfindungsgemäßen Elementen, die besonders dick ausgebildet ist, können vorteilhaft zusätzliche schalenförmige Verdrängungskörper auf den Schalen liegend in die Ortbetonschicht eingegossen sein.For a ceiling made of elements according to the invention, which is particularly thick, additional shell-shaped displacement bodies lying on the shells can advantageously be cast into the in-situ concrete layer.

In addition, the longitudinal reinforcements 5 are shown. Additional elements laid next to it are indicated on both sides of the element 1 '. In the left part of FIG. 4, a small part of an in-situ concrete layer 9 is also indicated, which is applied when the ceiling is finished using the ribbed ceiling element 1 'and which receives parts of the reinforcement 5 projecting over the element.
