Description

Verfahren zur Herstellung von Gegenständen aus Schaum- oder sonstigem Leichtbeton, insbesondere von Särgen Die Erfindung betrifft ein Verfahren zum Herstellen von Gegenständen, insbesondere von Särgen, aus Schaumbeton oder sonstigem Leichtbeton.Process for the production of objects from foam or other Lightweight concrete, in particular from coffins The invention relates to a method of manufacturing of objects, especially coffins, made of foam concrete or other lightweight concrete.

Es ist bereits bekannt, Gegenstände aus Schaum-oder :sonstigem Leichtbeton dadurch herzustellen, daß die Schaum- oder Lei.ehtbetonmasse, der zweckmäßig ein die Erstarrung der Masse beschleunigendes Mittel zugesetzt worden ist, in Formen gefüllt wird, in denen die Masse erstarrt. Zur endgültigen Verfestigung waren bisher etwa q. Wochen erforderli(ch, da die Betonmasse eine solche Zeit zum Abbinden und Festwerden benötigt. Die Erfindung bezweckt, dieses Verfahren wesentlich abzukürzen. Erfindungsgemäß wird die mit der Masse gefüllte Form in einem Druckkessel einer Dampfbehandlung bei einem hohen Druck von beispielsweise 6 bis 15 atü während einer Zeitdauer von etwa 6 bis 1a Stunden ausgesetzt. Auf diese Weise ist es möglich, Gegenstände aus Schaum- oder sonstigem Leichtbeton in etwa 1l/2 bis a Tagen herzustellen, wobei ;gleichzeitig die Festigkeit gegenüber dem bisherigen Verfahren wesentlich erhöht wird.Objects made of foam or other lightweight concrete are already known to produce by the fact that the foam or concrete concrete mass, which is expedient the solidification accelerating agent has been added in molds is filled, in which the mass solidifies. So far, for final solidification about q. Weeks required because the concrete mass has such a time to set and Needing to solidify. The invention aims to shorten this process significantly. According to the invention, the form filled with the mass in a pressure vessel is a Steam treatment at a high pressure of, for example, 6 to 15 atmospheres during one Exposure for a period of about 6 to 1a hours. In this way it is possible Manufacture objects from foam or other lightweight concrete in about 1l / 2 to a days, where; at the same time, the strength compared to the previous method is essential is increased.

Ein Ausführungsbeispiel des Verfahrens bei der Anwendung zur Herstellung von Särgen sei nachstehend näher erläutert: Ein zweckmäßig mit einem bekannten Abbindebeschleunigungsmittel versetzter Schaumbetonmörtel wird in eine metallische Form gefüllt, wobei der zu schaffende Hohlraum des Sarges durch .einen entsprechenden Kern erzeugt wird. Nach etwa einem Tage kann der Kern aus der Form herausgenommen werden, ohne daß befürchtet werden muß, daß die Masse in sich zusammensinkt. Die Form mit der in ihr enthaltenen Betonmasse wird dann in einen Druckkessel geschoben und darin einer Dampfbehandlung unter einem Druck von etwa 6 bis 15 atü während einer Zeitdauer von 6 bis 1a Stunden ausgesetzt. Die Wandungen der metallischen Form lösen sich infolge ihrer grUeren Ausdehnung in der Wärme von den Außenflächen des Betonkörpers, so daß sich dieser nach beendeter Behandlung leicht aus der Form entfernen läßt.An embodiment of the method in use for manufacture of coffins will be explained in more detail below: One expediently with a known setting accelerator offset foam concrete mortar is filled into a metallic mold, with the to creating cavity of the coffin by .a corresponding core is generated. To the core can be removed from the mold for about a day without fear will must that the mass collapse in on itself. The shape with the in it contained concrete mass is then pushed into a pressure vessel and therein steaming under a pressure of about 6 to 15 atmospheres for a period of time exposed for 6 to 1a hours. The walls of the metallic form loosen due to their greater expansion in the heat from the outer surfaces of the concrete body, so that it can be easily removed from the mold after the treatment has ended.
