Description
AUSGEGEBEfI AM 7. JULI 1919ISSUE FI ON JULY 7, 1919
Bei Hütten und Gebäuden zur Herstellung von Sprengstoffen, Munition u. dgl. verwendet
man bisher in der Regel Türen und Verschlußklappen aus Holz. Da diese aber im Falle
einer inneren Explosion gefährliche Schleuderstücke bilden, war es notwendig, die Umgebung
durch vorgesetzte, nötigenfalls ^bepflanzte Dämme zu schützen.
Nach vorliegender Erfindung sollen für solcheIn huts and buildings for the production of explosives, ammunition and the like, doors and closure flaps made of wood have hitherto been used as a rule. However, since these form dangerous slingshots in the event of an internal explosion, it was necessary to protect the surroundings by means of dams in front of them and, if necessary, planted dams.
According to the present invention are intended for such
ίο Zwecke Eisenbetontüren, Klappen u. dgl. verwendet werden, bei welchen ein dehnbares und leicht zerreißbares Metallnetzwerk lose in die metallene Türumrahmung eingelegt und in eine gleichmäßig dünne Schicht von Bimskalkzementbetön eingebettet ist.ίο Purposes reinforced concrete doors, flaps, etc. used in which a stretchable and easily tearable metal network is loosely inserted into the metal door frame and embedded in an evenly thin layer of pumice cement concrete.
Man kennt bereits Eisenbetontüren, beiReinforced concrete doors are already known at
welchen jedoch die Metalleinlage stets in einem eisernen "Rahmen fest eingespannt ist, undwhich, however, the metal insert is always firmly clamped in an iron "frame, and
> wobei die Umrahmung, mit stärkerem und die Metalleinlage mit dünnerem Beton umkleidet ist. In solchen Füllen bildet aber die Tür bei einer Explosion ein gefährliches Schleuderstück, da sie mit ihrer Umrahmung herausgerissen und weggeschleudert wird.> being the framing, with stronger and the Metal insert is lined with thinner concrete. But the door forms in such fills A dangerous slingshot in an explosion, as it was torn out with its frame and is thrown away.
Bei "der Tür gemäß vorliegender Erfindung ist die mit einer gleichmäßigen dünnen^, Bimskalkzementbetonschicht überzogene Metalleinlage lose in den eisernen Türrahmen eingelegt. Gegen gewöhnliche BeanspruchungenIn "the door according to the present invention is the one with a uniform thin ^, pumice cement concrete layer coated metal insert loosely inserted into the iron door frame. Against normal demands
besitzt die Tür eine genügende Festigkeit. Bei einer inneren Explosion werden die Füllungen aus den Rahmen herausgeblasen, wobei der Beton infolge der noch zu beschreibenden Eigenart der Metalleinlage zu Staub zerfällt, so daß sich also keinerlei gefährliche Wurfstücke bilden können.the door has sufficient strength. If there is an internal explosion, the fillings blown out of the frame, with the concrete as a result of the yet to be described The peculiarity of the metal insert disintegrates into dust, so that there are no dangerous pieces can form.
Bei starker Erhitzung treten keine wesentlichen Änderungen an der Tür ein, da sich die mit Beton umkleidete Einlage unabhängig von der eisernen Umrahmung ausdehnt und nach Erkaltung wieder in ihre frühere Lage zurückkehrt. Die Betonschicht hat infolge ihrer Zusammensetzung ungefähr dieselbe Ausdehnungszahl wie die Metalleinlage, so daß ' also auch die^Betonumkleidung in der Regel keinen Schaden leiden'^wird und man die Tür auch nach einem Brand weiter benutzen kann.If the door is heated to a great extent, no significant changes will occur, since the concrete-clad insert expands independently of the iron frame and returns to its previous position after cooling down. The concrete layer has as a result their composition roughly the same expansion factor like the metal insert, so that the concrete cladding as a rule also will not suffer any damage and will continue to use the door even after a fire can.
Nach vorliegender Erfindung werden in eine Metallumrahmung, z. B. aus dünnem U-Eisen oder Metallblech, eine oder mehrere dünne Metallnetztafelnjxiit leicht zerreiß- und dehnbaren^Maschen, wie Streckmetall ο. dgl., eingelegt, die mit einer gleichmäßigen dünnen Schicht von porösem, zähem Bimskalkzementbeton mit Zusätzen, wie z. B. Roßhaaren, Asbest oder Asbestfasern, bekleidet werden. Die zähe, dehnbare und somit gegen Rissebildung widerstandsfähige Mischung wird so gewählt,' daß die Ausdehnung der erhärteten Mischung bei Erhitzung!der Ausdehnung des eingelegten Metallnetzwerkes möglichst gleich kommt, was'durch eine^möglichst gleichmäßige Stärke der Betonfüllung begünstigt wird.'According to the present invention, in a metal frame, for. B. made of thin U-iron or sheet metal, one or more thin sheets of metal net jxi with easily tearable and stretchable meshes, like expanded metal ο. Like., inserted, with a uniform thin Layer of porous, tough pumice lime cement concrete with additives such as B. Horsehair, Asbestos or asbestos fibers. The tough, ductile and therefore against cracking resistant mixture is chosen so that the expansion of the hardened Mixing when heated! Is as equal as possible to the expansion of the inserted metal network comes, which 'is favored by a ^ as uniform as possible a thickness of the concrete filling.'
Auf diese Weise wird zunächst eine Feuersicherheit der Tür oder Klappe erreicht, denn der Türrahmen kann sich nunmehr in der Hitze 'vollständig frei und unabhängig von der Tür ausdehnen, so daß keine schädlichen Risse entstehen können. Ferner hat aber das dehn- und zerreißbare Metallnetzwerk noch die Wirkung, daß es im Falle einerIn this way, fire safety of the door or flap is first achieved because the door frame can now be completely free and independent of the heat the door so that no harmful cracks can occur. But also has the stretchable and tearable metal network still has the effect that it is in the case of a
Explosion die ganze Füllung durch Zerschneiden, Zerreißen und Zerdrücken in kleine Bruch-Stücke zerlegt, so daß' die Entstehung größerer Wurfstücke ausgeschlossen ist, zumal, da dasExplosion the whole filling by cutting it up, Tearing and crushing broken into small fragments, so that 'the emergence of larger ones Throwing pieces is excluded, especially since the
. 5 Metallnetzwerk wegen seiner losen Einlagerung in den Türrahmen diesen bei der Explosion nicht mitreißen kann.. 5 Metal network because it was loosely embedded in the door frame when it exploded can't get carried away.
Eine Ausführungsform, der Erfindung ist in den Fig. ι und 2 der Zeichnung ' in Ansicht und Höhenschnitt veranschaulicht.One embodiment of the invention is shown in FIG Figs. ι and 2 of the drawing 'illustrates in view and vertical section.
Innerhalb einer Umrahmung a, die aus dünnem U-förmigen Eisen oder Metall besteht, ist ein Netzwerk b lose eingelegt, welches aus leicht z'erreißbaren Maschen besteht, wie es beispielsweise bei dem bekannten Streckmetall der Fall ist! ' ' Within a frame a, which consists of thin U-shaped iron or metal, a network b is loosely inserted, which consists of easily tearable meshes, as is the case, for example, with the known expanded metal! ''
Bei dickeren Türen oder größeren Füllungen werden zweckmäßig zwei solcher Netzwerke nebeneinander angeordnet.For thicker doors or larger panels, two such networks are useful arranged side by side.
Die Türfüllung c besteht im übrigen aus einer gleichmäßig dünnen Betonlage, die in der oben beschriebenen Weise zusammengesetzt ist.The door panel c consists of a uniformly thin layer of concrete, which in is composed in the manner described above.
