   Ferner hat aber das dehn- und zerreissbare Metallnetzwerk noch die Wirkung, dass es im Falle einer Explosion die ganze Füllung in kleine Bruchstücke zerlegt, so dass die Entstehung grösserer Wurfstüoke ausgeschlossen ist, zumal da das Metallnetzwerk wegen seiner losen Einlagerung in den   Türrahmen   diesen bei   der Explosion nicht mitreissen   kann. 



   Die Erfindung ist in den Fig. 1 und 2 der Zeichnung in einer Ausführungsform- veranschaulicht. 



   Innerhalb einer Umrahmung a, die aus dünnem U-förmigem Eisen oder anderem Metall besteht, ist bei der gezeichneten Ausführungsform ein   Netzwerk b   lose eingelegt, welches aus leicht zerreissbaren Maschen besteht, wie es beispielsweise bei dem bekannten Streckmetall der 
 EMI2.1 
   werke nebeneinander angeordnet. nebeneinander angeordnet.   



   Die Türfüllung c besteht   aus   einer gleichmässig dünnen   Betonlage,   die in der oben beschriebenen Weise gemischt und mit den entsprechenden Zusätzen versehen ist. 



   Diese Tür ist nicht nur vollständig feuersicher sondern auch gegenüber gewöhnlichen Erschütterungen, wie sie   durch das Zuschlagen   der Tür, durch Stösse usw. hervorgerufen werden, hinreichend standsicher. Im Falle einer Explosion hingegen erleidet das eingebettete Netzwerk, dessen einzelne Maschenteile leicht dehnbar und zerréissbar sind, eine plötzliche Formänderung und lockert durch seine scheidende, reissende und zerdrückende   Wnkuu den porösen   Beton so weit, dass er in kleine Bruchstücke zerfällt. Das Entstehen grösserer Wurfstucke ist infolgedessen ausgeschlossen, zumal, da ein Einreissen der metallenen   Türumral1TllunlI     @g wegen   der losen Einlagerung des Netzwerkes nicht vorkommen kann.

   Furthermore, the stretchable and tearable metal network has the effect that in the event of an explosion it breaks the entire filling into small fragments, so that the formation of larger litter is excluded, especially since the metal network is loosely embedded in the door frame Explosion cannot carry it away.



   The invention is illustrated in FIGS. 1 and 2 of the drawing in one embodiment.



   Within a frame a, which consists of thin U-shaped iron or other metal, a network b is loosely inserted in the embodiment shown, which consists of easily tearable meshes, as is the case, for example, with the known expanded metal
 EMI2.1
   works arranged side by side. arranged side by side.



   The door panel c consists of an evenly thin layer of concrete, which is mixed in the manner described above and provided with the appropriate additives.



   This door is not only completely fire-proof but also sufficiently stable against normal vibrations, such as those caused by slamming the door, knocks, etc. In the event of an explosion, on the other hand, the embedded network, the individual mesh parts of which are easily stretchable and tearable, undergoes a sudden change in shape and loosens the porous concrete to such an extent that it breaks into small fragments due to its separating, tearing and crushing action. As a result, the creation of larger pieces of throw is excluded, especially since the metal door surrounds cannot tear due to the loose storage of the network.
