Abstract

Zum Herstellen von Hohlbausteinen wird Füllmasse (M) in eine Preßform (7) mit hochragenden Kerndornen (11) eingebracht, dann mittels eines in Kerndornrichtung wirkenden Preßstempels (5) formgebend verdichtet und schließlich der Formling (F) durch Ausziehen der Kerndorne (11) und Abziehen der Preßform (7) entformt.To manufacture hollow building blocks, filling compound (M) is placed in a Press mold (7) with towering core mandrels (11) introduced, then by means of a press ram acting in the direction of the core mandrel (5) compacting and finally the molding (F) by pulling out the core mandrels (11) and pulling them off demolded from the mold (7).

Um Hohlbausteine mit schmalen Stegen und engen Hohlkammern und unterschiedlicher Kernmaterialdichte erzeugen zu können, werden die Kerndorne (11) vor Beginn des Verdichtens über die Füllhöhe (H) der Füllmasse (M) in der Preßform (7) hochgefahren und dann während des Verdichtens wieder zurückgezogen, wobei die von unten in die Preßform (7) einfahrbaren Kerndorne (11) in Durchtrittsöffnungen (15) einer am Preßstempel (5) sitzenden Preßplatte (14) eindringen.

Figure 00000001
In order to be able to produce hollow building blocks with narrow webs and narrow hollow chambers and different core material densities, the core mandrels (11) are raised above the filling height (H) of the filling mass (M) in the mold (7) before the compression and then withdrawn again during the compression The core mandrels (11), which can be inserted into the press mold (7) from below, penetrate through openings (15) of a press plate (14) seated on the press die (5).
