  Deckenelement, insbesondere Deckenplatte aus Schwer-oder Leichtbeton 
 EMI1.1 
 

 <Desc/Clms Page number 2> 

 Plattenuntersicht erst nach etwa 105 min zerstört. 



   Die Brandstandzeit des   erfindungsgemässen   Deckenelementes kann über das vorgeschriebene Mass noch erhöht werden, wenn an der Unterseite des Deckenelementes eine feuerfeste Matte vorgesehen wird, die auch eine Verringerung der Dicke der Betonschicht unterhalb der Tragbewehrung ermöglicht. 



   Die schlaffe Bewehrung kann auch bei leichten Deckenelementen angeordnet werden, die aus   Hochofenschlacken-,     Leca-oder   Perlitbeton hergestellt sind. 



   In der Zeichnung ist als Ausführungsbeispiel des Erfindungsgegenstandes eine Deckenplatte im Querschnitt dargestellt. In dem   Betonkörper--l--sind   nahe der Plattenuntersicht die vorgespannten   Stäbe--2--der   Tragbewehrung angeordnet, über der die   Stäbe--3--der   schlaffen oder gering vorgespannten Bewehrung liegen. Mit--4--ist die Transportbewehrung bezeichnet.

  Ceiling element, in particular ceiling plate made of heavy or lightweight concrete
 EMI1.1
 

 <Desc / Clms Page number 2>

 The underside of the plate is only destroyed after about 105 minutes.



   The fire service life of the ceiling element according to the invention can be increased beyond the prescribed level if a fireproof mat is provided on the underside of the ceiling element, which also enables the thickness of the concrete layer below the supporting reinforcement to be reduced.



   The slack reinforcement can also be arranged in light ceiling elements made from blast furnace slag, Leca or perlite concrete.



   In the drawing, a ceiling plate is shown in cross section as an embodiment of the subject matter of the invention. In the concrete body - 1 - the prestressed bars - 2 - of the supporting reinforcement are arranged near the slab underside, over which the bars - 3 - of the slack or slightly prestressed reinforcement lie. With - 4 - the transport reinforcement is designated.
