    Betondeeke.   



   Betondeeken mit Hohlkörpern, deren obere Platte stärker ausgebildet ist und als Druckgurt in der Decke verwendet wird, sind bekannt. Auch ist es nicht neu, bei Betondecken mit Hohlkörpern, die mit besonderen Erhöhungen versehen sind, diese im Bereiche der negativen Momente um   1800 gedreht   zu verlegen, um einen freien Raum zur Herstellung eines unteren Betondruckgurtes zu schaffen. Die Erfindung liegt nun darin, dass bei Decken der erstangeführten Art die Hohlkörper mit der verstärkten Platte im Bereich der negativen Momente um   1800 gedreht   verlegt sind, so dass die nach unten zu liegen kommende stärkere Platte des Hohlkörpers als Druckgurt dient. 



   Wie die Zeichnung zeigt, ist der Hohlstein F so hergestellt, dass eine seiner beiden Platten stärker als die zweite ausgeführt wird. Die stärkere Platte P bildet im Bereiche der positiven Momente die statisch erforderliche Druckzone der Decke. Zur Aufnahme der   Einspannungs- bzw. Stützenmomente   werden die Steine F gemäss der Erfindung im Bereiche der negativen Momente um   1800 gedreht   verlegt, d. h. mit der starken Platte P nach unten. Der unten erforderliche Druekgurt wird nun von den Platten P des Hohlkörpers F gebildet.

    Betondeeke.



   Concrete ceilings with hollow bodies, the upper plate of which is made thicker and used as a pressure belt in the ceiling, are known. In the case of concrete ceilings with hollow bodies that are provided with special elevations, it is also not new to install them rotated by 1800 in the area of the negative moments in order to create a free space for the production of a lower concrete pressure belt. The invention lies in the fact that in the case of ceilings of the type mentioned above, the hollow bodies with the reinforced plate are rotated by 1800 in the area of the negative moments, so that the thicker plate of the hollow body coming down serves as a compression belt.



   As the drawing shows, the hollow stone F is made in such a way that one of its two plates is made stronger than the second. The thicker plate P forms the statically required pressure zone of the ceiling in the area of the positive moments. According to the invention, the stones F are rotated by 1800 in the area of the negative moments to accommodate the restraint or support moments, i.e. H. with the strong plate P down. The pressure belt required below is now formed by the plates P of the hollow body F.
