Description

Verfahren zur Herstellung von Dielen und anderen, vorwiegend flächenhaft ausgebildeten Körpern aus Zement und anderen abbindenden lassen mit Drahtbewehrung. . Es werden bereits schwächere Zementdielen hergestellt, die bei einer Länge von beispielsweise 2 m jedoch immer noch eine Stärke von q. cm aufweisen. Hierbei werden Eisendrähte von etwa q. mm Stärke in einer Entfernung von 4. bis ß cm voneinander als Bewehrung eingebettet. Sie liegen in der Regel i/2 cm unter der Oberfläche der Diele.Process for the production of floorboards and others, mainly flat formed bodies of cement and other setting leave with wire reinforcement. . Weaker cement boards are already being produced, with a length of for example 2 m, however, still has a thickness of q. cm. Here will be Iron wires of about q. mm thickness at a distance of 4 to ß cm from each other embedded as reinforcement. They are usually i / 2 cm below the surface of the Hallway.

In dieser Ausführungsart konnten schwächere Dielen bis herab zu io und 6 mm Stärke, wie solche nach der Erfindung angestrebt werden und wie sie der Erfinder bereits versuchsweise hergestellt hat, nicht erzeugt werden.In this design, weaker planks could be down to io and 6 mm thickness, as those are aimed for according to the invention and how they are Inventor has already manufactured on a trial basis, cannot be generated.

Die Erfindung bezweckt, eine möglichst geringe Dielenhöhe zu erzielen. Das Verfahren gemäß der Erfindung weicht von dem bisher üblichen zunächst dadurch ab, daß die einzelnen starken Bewehrungsdrähte förmlich aufgelöst sind in eine groß e Anzahl viel schwächerer Drähte, welche, in dichter Scharung eng aneinanderliegend, ganz an die Ober- bzw. an die Unterfläche der Diele o. dgl. verlegt sind, so daß der bisher übliche Abstand der Bewehrungsdrähte von der Oberfläche des Formlings gänzlich aufgegeben ist. Der große Abstand der Bewehrungsdrähte von der Oberfläche der Formlinge war bei der bisherigen allgemein üblichen Bewehrungsweise wegen der Gefahr des Austretens des stärkeren Eisens aus der Formmasse nötig. Bei Schwachdrahtbewehrung dagegen, wie sie gemäß der Erfindung unter Anspannung der Drähte angewendet werden, ist es unnötig, die Drähte in größerer Entfernung von der Oberfläche der Formlinge einzubetten. Zu dieser Erkenntnis hat die Beobachtung geführt, daß durch ein Verlegen der Drähte ganz an die Oberfläche bei Auflösung des erforderlichen Eisenquerschnittes in viele schwache Drähte infolge der gewonnenen größeren Oberfläche das Vielfache an Haftfläche und Sicherheit gegen Austreten gewonnen wird. So tritt beispielsweise ein Gewinn von ioo Prozent an Haftfläche ein bei Ersatz eines starken Drahtes durch nur q. schwache Drähte halben Durchmessers, also bei gleichem Gesamtquerschnitt dieser Drähte.The invention aims to achieve the lowest possible board height. The method according to the invention initially differs from the hitherto customary method from the fact that the individual strong reinforcing wires are literally dissolved into one large e number of much weaker wires, which, closely clustered together, are completely relocated to the upper or lower surface of the board or the like, so that the usual distance between the reinforcing wires and the surface of the molding is completely abandoned. The great distance between the reinforcement wires and the surface the briquettes were with the previous generally usual method of reinforcement because of the Risk of the stronger iron leaking out of the molding compound. With weak wire reinforcement on the other hand, as they are applied according to the invention under tension of the wires, it is unnecessary to keep the wires at a greater distance from the surface of the briquettes to embed. The observation that through an embarrassment led to this realization of the wires to the surface with the dissolution of the required iron cross-section many weak wires due to the larger surface area gained is gained in terms of adhesive surface and security against leaking. So occurs, for example a gain of 100 percent in adhesive surface when replacing a strong wire only q. weak wires of half the diameter, i.e. with the same overall cross-section these wires.

Der Zweck der Verlegung der schwachen Drähte an die Oberfläche ist die Vergrößerung der Höhe des wirksamen Querschnittes. Die Auflösung in viele schwache Drähte ist Mittel zu diesem Zweck, weil starke, vereinzelt liegende Drähte aus der Oberschicht der Formlinge austreten würden. Die dichte Lage schwacher Drähte, wenn auch nebeneinander, ersetzt förmlich die Wirkung der Oberfläche bei einer Eisenplatte, bei welcher insbesondere die oberste und die unterste Faser die Beanspruchungen aufnehmen.The purpose of laying the weak wires to the surface is the increase in the height of the effective cross-section. The dissolution into many weak Wires is a means to this end because strong, isolated wires come from the Upper layer of the briquettes would emerge. The dense layer of weak wires, though also next to each other, literally replaces the effect of the surface on an iron plate, in which, in particular, the top and bottom fibers bear the stresses take up.

Um das gleichmäßige Verlegen der dünnen Drähte nahe aneinander in einer Ebene und mit der Oberfläche abschneidend zu- erzielen, ist es erforderlich, die Drähte bei dem Einlegen, in die Form anzuspannen und bis zur Erhärtung der Masse in angespanntem Zustande zu belassen. Das Verlegen von gespannten Drähten ist zwar bei manchen Baubestandteilen, wie Putzträgern, Baukörpern quadratischerQuerschnittsform, z.B. Pfählen, und auch zur Herstellung biegsamer Stuckplatten nicht mehr neu, dagegen ist die Verwendung schwacher, gespannter Drähte zur Herstellung von Dielen, schwachen Latten und Riegeln, zum Zwecke, diese unmittelbar an die Oberfläche und Unterfläche der Formlinge zu verlegen, neu.In order to evenly lay the thin wires close to each other in to achieve a plane and cut off with the surface, it is necessary to Tighten the wires when inserting them into the mold and until the mass hardens to leave in a tense state. The laying of tensioned wires is true for some building components, such as plaster bases, structures with a square cross-sectional shape, e.g. piles, and also for making flexible ones Not stucco panels more new, however, is the use of weak, tensioned wires for production from floorboards, weak battens and bars, for the purpose of bringing them directly to the surface and to lay the undersurface of the bricks, new.

Solche Dielen sind 6 bzw. io bis 30 mm stark und etwa 35 cm breit, bei einer Länge von 2 bis 6 m. Teillängen werden durch Zerschneiden erzielt.Such boards are 6 or 10 to 30 mm thick and about 35 cm wide, with a length of 2 to 6 m. Partial lengths are achieved by cutting.

Zum Spannen der Drähte können diese entweder bereits in der richtigen Anordnung zueinander ausgespannt in die Form eingebracht oder auch unmittelbar auf die Formbretter aufgespannt werden und bleiben bis zur Erhärtung des Zements in Spannung. Hierbei ist es gleichgültig, ob die Drähte ganz gerade in der einen oder an beiden Oberflächen liegen oder ob sie der Länge nach zickzackförmig oder schlangen-. förmig verlaufen.To tension the wires, they can either already be in the correct Arrangement in relation to one another, introduced into the mold or also directly on it the molding boards are stretched and remain in place until the cement hardens Tension. It does not matter whether the wires are straight in one or the other lie on both surfaces or whether they are zigzag or serpentine lengthways. run in a shape.

Die Verlegung der Drähte unmittelbar in die Oberfläche behufs voller Ausnutzung der Querschnittshöhe und Erzielung ganz schwacher Dielen bedingt das Anspannen der Drähte in der Form bis zur Erhärtung der Masse.Laying the wires directly into the surface for full This requires the use of the cross-section height and the achievement of very weak planks Tension the wires in the mold until the mass hardens.

Als Material für die Platten dient hauptsächlich Zement, wobei zur Bewehrung insbesondere Eisendrähte in Betracht kommen. Die Drähte können entweder einzeln jeder für sich zur Anspannung gelangen oder auch vor der Anspannung zu fertigen Geweben verflochten und als solche verarbeitet werden. Der Rostschutz ist durch Anstrich, Putz, Bekleben mit Dachpappe, Verwendung von verzinkten Drähten oder anderen Rostschutzmitteln erreichbar.The main material used for the panels is cement, with Reinforcement in particular iron wires come into consideration. The wires can either individually each to get to the tension or to manufacture before the tension Fabrics are intertwined and processed as such. The rust protection is through Painting, plastering, covering with roofing felt, using galvanized wire or other things Anti-rust agents achievable.

Für gewisse Zwecke, und zwar für Schalungen, Decken und Wandverkleidungen, können die Dielen aus Leichtmaterial, wie Gips, 11agnesit, hergestellt werden.For certain purposes, namely for formwork, ceilings and wall cladding, the planks can be made of light material such as plaster of paris or magnesite.
