Description

Formplatte zur Herstellung von Zementdachziegeln. Die Erfindung betrifft eine weitere Ausbildung der bewehrten Betonformplatte zur Herstellung von Zementdachziegeln in Schlagplattenmaschinen nach Patent 364672. Mold plate for the production of cement roof tiles. The invention relates to a further embodiment of the reinforced concrete mold plate for the production of cement roof tiles in impact plate machines according to patent 364672.

Nach diesem Patent werden außer dem weitmaschigen, die ganze Fläche der Formplatte bedeckenden Drahtgewebe unmittelbar an den Kanten der Formplatte noch schmale Streifen von feinmaschigem Drahtgewebe eingebettet. Diese Drahtgewebestreifen haben jedoch folgenden Nachteil: Bei der Herstellung der Formplatte muß der Betonrand abgegratet werden. Hierbei wird der Betonrand leicht verletzt, und es entstehen durch die vielen feinen Drähte des im Betonrand eingebetteten feinmaschigen Drahtgewebes leicht nach außen offene Poren oder Kanäle. Nun werden beim Gebrauch die Formplatten geölt, um durch Bildung einer Isolierschicht zwischen Formplatte und Ziegel das -Anhaften zu verhindern. Durch die Poren am Rand kann nun das Öl in die Formplatte eindringen und sie allmählich zerstören. Der Erfindung gemäß werden diese Nachteile dadurch beseitigt, daß an Stelle der feinmaschigen Drahtgewebestreifen eine den Ein- und Ausbuchtungen der .Plattenkante entsprechende, aus Blechstreifen bestehende Einlage in den Beton Eiach so eingebettet wird, daß sie nach außen über den Betonrand hervorsteht. Es fallen also das Abgraten des Betonrandes der Formplatte und die hiermit verbundenen Nachteile fort.According to this patent, apart from the wide mesh, the whole area the wire mesh covering the mold plate directly at the edges of the mold plate still narrow strips of fine-mesh wire mesh embedded. These wire mesh strips however, have the following disadvantage: When producing the molded plate, the concrete edge must be trimmed. Here, the edge of the concrete is easily damaged, and it occurs through the many fine wires of the fine-mesh wire mesh embedded in the concrete edge pores or channels that are slightly open to the outside. Now the mold plates are in use oiled in order to achieve the -Prevent sticking. The oil can now enter the mold plate through the pores on the edge penetrate and gradually destroy them. According to the invention These disadvantages are eliminated by the fact that instead of the fine-mesh wire cloth strips one of the indentations and bulges of the .plate edge corresponding, made of sheet metal strips existing insert is embedded in the concrete Eiach in such a way that it extends over to the outside the concrete edge protrudes. So there is the deburring of the concrete edge of the mold plate and the associated disadvantages continue.

Der Erfindungsgegenstand ist in der Zeichnung in einem Ausführungsbeispiel veranschaulicht, und zwar zeigt: Abb. i das Drahtgewebe mit der profilierten Blecbstreifeneinlage in schaubildlicher Darstellung, Abb.2 einen Querschnitt durch die Formplatte in vergrößertem Maßstabe.The subject of the invention is shown in the drawing in an exemplary embodiment illustrated, namely shows: Fig. i the wire mesh with the profiled sheet metal insert in a diagrammatic representation, Fig. 2 shows a cross section through the mold plate in enlarged scale.

In den Abbildungen bedeutet a das feinmaschige Drahtgewebe, das in die Betonformplatte b eingebettet ist. Mit c, d, e und f sind die sich an die Drahteinlage anschmiegenden Blechstreifen bezeichnet, die entweder an den Plattenecken nur aneinandergelegt oder auch in sonst üblicher Weise" z. B. durch Schweißen zu einem geschlossenen. Rahmen, verbunden werden können. Von diesen Blechstreifen sind die in den Längskar= ten der Formplatte liegenden Streiften c und e gerade, während die in den Querkanten liegenden Streifen d und f dem Querprofil der Platte entsprechend profiliert sind. An den. Stellen g sind die Blechstreifen eingeschnitten und die eingeschnittenen Teile nach unten abgebogen, um durch diese abstehenden Fortsätze Bern Beton eine größere Anlagefläche zu geben und somit die Blechstreifen in die Formplatte b sicherer einzubetten. An Stelle dieser Einschnitte können selbstverständlich auch die Blechstreifen in geeigneter Weise ausgebuchtet oder gewölbt werden. In Abb. -- rechts sind die Fortsätze durch Ausstanzen. hergestellt.In the figures, a means the fine-mesh wire mesh that is embedded in the concrete mold plate b. With c, d, e and f the sheet metal strips nestling against the wire insert are designated, which can either only be placed next to one another at the plate corners or can also be connected in the usual way, for example by welding to form a closed frame The strips c and e lying in the longitudinal cards of the shaped plate are straight, while the strips d and f lying in the transverse edges are profiled according to the transverse profile of the plate bent to give through this protruding appendages Bern concrete a larger contact surface and thus the metal strip in the mold plate b securely embed Instead of these cuts can of course bulged the metal strips in a suitable manner or curved Figure -... are right Extensions produced by punching.
