Description

Explosionssichere Metalltür Die Türen der Transformatorenräume, Ölschalterzellen u. dgl., also Räume, in. denensich im Innern ein Überdruck,. sei es durch Explosion oder durch die einer Explosion vorangehende Druckerscheinung, bilden kann, werden vielfach mit lose eingebauten Klappen versehen, welche im Falle einer Explosion den auftretenden Drücken ausweichen sollen. Diese Klappen haben aber den Nachteil der schlechten Dichtigkeit und- sind.,,ußerdem nicht gegen unbefugtes Öffnen von außen her gesichert.Explosion-proof metal door The doors of the transformer rooms, oil switch cells and the like, i.e. rooms in which there is an overpressure inside. be it by explosion or by the pressure phenomena preceding an explosion often provided with loosely built-in flaps, which in the event of an explosion to avoid the occurring pressures. However, these flaps have the disadvantage the bad tightness and- are. ,, also not against unauthorized opening of secured from the outside.

Die Erfindung besteht darin, diese Nachteile zu beseitigen und die in obengenannten Räumen auftretenden Explosionen möglichst unschädlich zu machen.The invention consists in eliminating these disadvantages and the to make explosions occurring in the above-mentioned rooms as harmless as possible.

Die Türfüllungen sind nach der Erfindung zwischen Falzen von ungleicher Leistenbreite eingesetzt, so daß ein oder mehrere Felder bei einem Explosionsüberdruck herausfliegen können, der Hauptteil der Türrahmen aber erhalten bleibt; andererseits ist ein Eindrükken der Bleche, die die Türfüllungen bilden, infolge des breiten inneren Falzes nicht möglich.According to the invention, the door panels are unequal between folds Bar width used, so that one or more fields in the event of an explosion overpressure can fly out, but the main part of the door frame remains intact; on the other hand is an impression of the metal sheets that make up the door panels due to their width inner fold not possible.

Der Erfindungsgegenstand ist in der beiliegenden Zeichnung an einem Ausführungsbeispiel veranschaulicht: Abb. i zeigt eine Tür in Ansicht mit einem Explosionsfeld, Abb. z eine solche mit zwei Feldern, Abb. 3 einen wagerechten Schnitt zu Abb. i und 2.The subject of the invention is in the accompanying drawing on a Exemplary embodiment illustrated: Fig. I shows a door in view with a Explosion field, Fig. Z one with two fields, Fig. 3 a horizontal section to fig. i and 2.

Die Türfüllung a wird lose zwischen den ungleich breiten Falzen b und c des Umrahinungsprofiles d gehalten. Der auf der Überdruckseite (Innenseite) längere Falz c verhindert ein;,ünbefugtes Eindrücken des Explosionsfeldes ca von der Außenseite aus; dagegen läßt der Falz b bei entsprechender Biegungsbeanspruchung der Türfüllung, hervorgerufen durch Explosionsdruck o. dgl., ein Herausfliegen derselben zu, ohne daß der Türrahmend mit Schloß, Scharnieren, -Mauerrahmen usw. beschädigt wird.The door panel a is held loosely between the unequally wide folds b and c of the Umrahinungsprofiles d. The fold c, which is longer on the overpressure side (inside), prevents unauthorized pressing of the explosion field ca from the outside; on the other hand, if the door panel is subjected to bending stress caused by explosion pressure or the like, the fold b allows it to fly out without damaging the door frame d with the lock, hinges, wall frames, etc.
