AUSGEGEBEN AM 17. JULI 1919ISSUED ON JULY 17, 1919
Den Gegenstand der vorliegenden Erfindung bilden Hütten und Gebäude für die Herstellung und Lagerung von Spreng- und Explosivstoffen. - .The subject of the present invention are cottages and buildings for manufacture and storage of explosives. -.
Man hat bereits Gebäude dieser Art aus Beton mit einer Einlage aus einem den Raum käfigartig umschließenden Metallnetzwerk hergestellt, wobei ein zu großer Härte abbindender Beton verwendet wurde, und das eingebetteteOne already has buildings of this type made of concrete with an insert from one of the rooms Cage-like surrounding metal network produced, with too great a hardness setting Concrete was used and that embedded
ίο Metallnetzwerk aus entsprechend angeordneten Stäben aus Rundeisen o. dgl. zusammengesetzt war.ίο Metal network made of appropriately arranged Rods from round iron o. The like. Was composed.
Hierdurch wird aber nicht verhindert, daß sich bei Innenexplosionen große Wurfstücke bilden, < die die Nachbarschaft gefährden, da der harte Beton bei der Zertrümmerung in große Bruchstücke zerfällt, die, aus dem Zusammenhang der -Eisen herausgerissen, durch die Explosion fortgeschleudert werden und deren Gefahr für die Nachbarschaft vergrößern.However, this does not prevent large debris from forming in the event of an internal explosion form <which endanger the neighborhood, as the hard concrete breaks into large fragments disintegrate, which, torn out of the context of the iron, through the explosion will be thrown away and increase its danger to the neighborhood.
Die vorliegende Erfindung beruht auf derThe present invention is based on
Erkenntnis, daß Baulichkeiten der in Frage kommenden Art zwar trotz möglichst leichter Ausführung genügend standsicher sein müssen, um geringere Erschütterungen ohne Beschädigung aushalten zu können, daß sie aber gleichzeitig so hergestellt sein müssen, daß die Wandungen bei einer Innenexplosion mit Sicherheit in kleine Stücke zerfallen und keine größeren Wurfstücke, bilden können.Realization that buildings of the type in question may be lighter despite the fact that they are as easy as possible Execution must be stable enough to withstand minor vibrations without damage to be able to endure, but at the same time they must be made in such a way that the In the event of an internal explosion, walls will certainly fall apart into small pieces and none larger litter pieces.
Als Baustoff wird deshalb ein poröser, leicht zerstörbarer Beton, z. B. Bimskalkzementbeton, verwendet, der schon nach sehr kurzer Abbindezeit seine höchste Festigkeit erreicht, die wesentlich unterhalb der höchsten Festigkeit anderer Betonarten liegt. In die aus solchem Baustoff hergestellten Seiten- und Deckenwandungen wird nach statischen Bewehrungsgrundsätzen ein den umbauten Raum käfigartig umschließendes, dehnbares und leicht zerreißbares Metallnetzwerk aus Streckmetall oder ähnlicher Art eingebettet.As a building material, a porous, easily destructible concrete, z. B. Pumice cement concrete used, which is already very short setting time reaches its highest strength, which is significantly below the highest Strength of other types of concrete. In the side and side panels made from such building material Ceiling walls are built into the enclosed space according to static reinforcement principles Cage-like, stretchable and easily tearable metal network made of expanded metal or similar type embedded.
Auf solche Weise hergestellte Baulichkeiten haben genügende Standfestigkeit, um einerseits Erschütterungen, wie sie z. B. bei Explosipnen benachbarter Gebäude vorkommen, und andererseits die Belastung des Daches mit einer entsprechend starken Erdschicht aushalten zu können. Findet aber im Innern· eines so hergestellten Gebäudes selbst eine Explosion statt, so wird durch das in die Wandungen eingebettete, leicht zerreißbare Metallmaschennetz aus Streckmetall der schon an sich leicht zerstörbare Baustoff zu Staub zermalmt oder in kleine Bruchstücke zerlegt. Bei der Explosion wird die Betonschicht durch die messerartig senkrecht zur Wandfläche gerichteten Maschenstege des Streckmetalls in Stücke von Maschengröße unterteilt. Gleichzeitig erleidet das Streckmetall eine plötzliche Formveränderung, die sich in einer Gestaltsänderung der Maschen äußert, derart, ' daß die Maschen das von ihnen umfaßte Material noch weiter zermürben. Eine Loslösung der Streckmetalleinlage aus dem Beton kann nur unter gleichzeitiger vollständiger Zermalmung des Betons erfolgen, so daß sich größere Wurfstücke wie bei einem aus Rundeisen o. dgl. zusammengesetzten kräftigeren Metallnetzwerk nicht bilden können. Die Streckmetalleinlage selbst wird infolge ihrer leichten Zerreißbarkeit ebenfalls in kleinere Stücke zerlegt, die schonStructures produced in this way have sufficient stability to on the one hand Shocks such as those caused by B. occur in the case of explosions in neighboring buildings, and on the other hand, the load on the roof to be able to withstand with a correspondingly thick layer of earth. But finds inside of a building produced in this way an explosion takes place itself, so is caused by the in the The easily tearable metal mesh network made of expanded metal is embedded in the walls Easily destructible building material is crushed to dust or broken down into small fragments. In the explosion, the concrete layer is directed through the knife-like perpendicular to the wall surface Mesh bars of expanded metal divided into pieces of mesh size. Simultaneously the expanded metal suffers a sudden change in shape, which manifests itself in a change in the shape of the mesh, such that 'that the meshes wear down the material they contain. A detachment of the Expanded metal insert from the concrete can only be done with simultaneous complete crushing of the concrete, so that larger pieces like a round iron o. composite stronger metal network can not form. The expanded metal insert itself, due to its easy tearability, is also broken up into smaller pieces, which already
