Description
Die bekannten Betonmäntel für Kesselöfen müssen, um genügende Haltbarkeit vorauszusetzen,eine beträchtliche Wandstärke aufweisen; hierdurch werden sie aber, abgesehen vom hohen Materialverbrauch, auch ziemlich schwer und für den Transport daher ungeeignet. Durch nachstehend beschriebene Erfindung soll nun ein Mantel geschaffen werden, der durch eingeschlossene Hohlkörper nicht nur eine Verminderung des Gewichts, sondern auch eine wesentliche Versteifung des Betons herbeiführt, so daß derartige Mäntel leicht und ohne Bruchgefahr fortgeschafft werden können.The known concrete jackets for boiler furnaces must, in order to provide sufficient durability, a have considerable wall thickness; but this makes them, apart from the high Material consumption, also quite heavy and therefore unsuitable for transport. By The invention described below is now to provide a jacket that is enclosed by Hollow body not only reduces weight, but also significantly stiffens the concrete, so that such jackets can be removed easily and without the risk of breakage.
Die Herstellung solcher Kesselmäntelgeschieht auf folgende Weise. Um ein als innere Form dienendes, nach unten zu konisch zulaufendes Rohrstücke (Fig. ι und Fig.·2) werden eine Anzahl aus Blech gebogene Rohre δ angeordnet, um diese wird ein Drahtnetz c geschlungen,The manufacture of such boiler shells is carried out in the following way. A number of tubes δ bent from sheet metal are arranged around a tube piece that is used as an inner shape and tapering downwards (Fig. 1 and Fig. 2), around which a wire mesh c is wrapped,
ao welches durch Röhren von geringerem Durchmesser d weiteren Halt bekommt. Ein zweiteiliges Rohr e, das durch Winkellaschen f mittels Schrauben in zwei Hälften zerlegt werden kann, bildet die äußere Form.ao which gets further support through tubes of smaller diameter d. A two-part tube e, which can be split into two halves by means of angle brackets f and screws, forms the outer shape.
Die zwischen innerer Form α und äußerer Form e entstandenen Hohlräume g werden, nachdem noch für das Feuergeschränk der Rahmen und für Rauchabzugsrohr, Wasserablaß usw. zur Schaffung dieser Hohlräume Formstücke eingesetzt wurden, mit Zementbeton ausgestampft. The cavities g created between the inner shape α and the outer shape e are stamped out with cement concrete after the frame for the fire cupboard and fittings for the smoke outlet pipe, water drain, etc. have been used to create these cavities.
Die Rohre b und d bestehen aus kreisförmig gebogenem Blech, dessen Kanten stumpf gegeneinanderstoßen. Durch diesen offenen Schlitz kann beim Einstampfen des Betons das Wasser eintreten und sich später beim Abbinden gut auf die eingestampfte Masse verteilen. Hierdurch wird die Betonmasse möglichst lange feucht erhalten, was für ihre Haltbarkeit von größtem Wert ist.The tubes b and d consist of circularly bent sheet metal, the edges of which butt against each other. The water can enter through this open slot when the concrete is tamped and later spread over the tamped mass when it sets. As a result, the concrete mass is kept moist for as long as possible, which is of great value for its durability.
Um die Rohre b nicht an die innere Form herantreten zu lassen, damit sie nach der Fertigstellung nicht an der Berührungsstelle freiliegen, werden geeignete Klötze h zwischen a und b gelegt und zu deren Halt um die Rohre b ein Draht geschlungen, der durch das Loch i gesteckt wird (Fig. 3).In order not to allow the tubes b to approach the inner form so that they are not exposed at the point of contact after completion, suitable blocks h are placed between a and b and a wire is looped around the tubes b to hold them, which passes through the hole i is plugged (Fig. 3).
