Abstract

Zur Fertigung eines Deckenelements (1) aus Beton, das mit einer überstehenden Bewehrung (3) in einer Schalung (4) mit verringertem Materialeinsatz, aber sicherer Statik vorgefertigt wird, wird vorgeschlagen, dass die Hauptfläche der Schalung (4) zur Ausbildung einer im Montagezustand an der Oberfläche konvexen Betonplatte (2) konkav ausgeformt ist. Insbesondere ist das Maß der konvexen Überhöhung im mittlerer Bereich der Betonplatte (2) in Anpassung an das Eigengewicht und die vorgesehene Auflast sowie Schwinden des Betons derart gewählt ist, dass das Deckenelement (1) im Einbauzustand annähernd plan ist. Weiterhin wird eine Schalung zur Herstellung eines solchen Deckenelements (1) vorgeschlagen, wobei das Maß der konkaven Vertiefung der Schalung (4) einstellbar ist, insbesondere durch Beaufschlagung mit zumindest einem Hydraulikzylinder.

For the production of a ceiling element (1) made of concrete, which is prefabricated with a protruding reinforcement (3) in a formwork (4) with reduced material use, but safe statics, it is proposed that the main surface of the formwork (4) to form a in the assembled state on the surface convex concrete slab (2) is concave. In particular, the degree of convex elevation in the middle region of the concrete slab (2) in adaptation to the own weight and the intended load and shrinkage of the concrete is selected such that the ceiling element (1) is approximately flat in the installed state. Furthermore, a formwork for producing such a ceiling element (1) is proposed, wherein the degree of concave depression of the formwork (4) is adjustable, in particular by applying at least one hydraulic cylinder.
