Description
Verfahren zur Formgebung von Hohlblock-Kunststeinen, insbesondere aus Beton- oder Kalksandsteinmasse Die Erfindung bezieht sich auf die Formgebung der Rohlinge von als Hohlblock- oder Lochsteine ausgebildeten Kunststeinen, deren Ausgangsmaterial ein wenig feuchtes Gemisch von verschiedenen Stoffen (z. B. Betonsteine, Kalksandsteine) ist. Bei der Herstellung solcher Steine wird das Rohgut üblicherweise in eine Form eingefüllt, welche mit die Höhlungen des Steines ergebenden Kernen ausgerüstet ist und dann durch Pressen, Stampfen, Rütteln (Vibrieren) usw. verdichtet. Insbesondere bei Steinen mit einer großen Anzahl von durch dünne Stege getrennten Höhlungen erweist sich aber das Einfüllen des Rohgutes in die Zwischenräume zwischen den Kernen als umständlich und schwierig, und es kommt gelegentlich vor, daß durch die Bildung von Materialbrücken zwischen den Kernen die Form ungleichmäßig oder unvollständig gefüllt wird, was zu Stellen ungenügender Festigkeit im Stein führen kann.Method for shaping hollow block artificial stones, in particular from concrete or sand-lime brick mass The invention relates to the shaping the blanks of artificial stones designed as hollow blocks or perforated stones, whose Starting material a slightly damp mixture of different substances (e.g. concrete blocks, Sand-lime bricks) is. In the production of such stones, the raw material is usually filled in a mold, which with the cavities of the stone resulting cores and then compacted by pressing, tamping, shaking (vibrating), etc. Especially with stones with a large number of separated by thin webs However, the filling of the raw material into the spaces between proves to be cavities the kernels as cumbersome and difficult, and it occasionally happens that by the formation of material bridges between the cores make the shape uneven or is incompletely filled, which leads to insufficient strength in the stone can.
Die Aufgabe, die sich die Erfindung gestellt hat, ist die, ein Verfahren zur Formgebung der Rohlinge solcher Höhlblock-Kunststeine vorzuschlagen, bei welchem die erwähnten Mängel zuverlässig vermieden werden. Die Erfindung macht dabei davon Gebrauch, däß eine Masse von der Art des zur Herstellung von solchen Kunststeinen verwendeten Rohgutes, wenn sie hochfrequenten Schwingungen ausgesetzt wird, in einen fließfähigen Zustand versetzt wird, und nutzt diesen Zustand zur Herstellung der Hohlblock-Kunststeine aus, indem zur Bildung der Hohlräume die hierzu. erforderlichen Kerne in diesem Zustand und damit mühelos in die Masse eingesenkt werden.The task set by the invention is to provide a method to propose for shaping the blanks of such cave block artificial stones, in which the defects mentioned can be reliably avoided. The invention makes of it Use that a mass of the kind for the manufacture of such artificial stones raw material used when it is exposed to high-frequency vibrations into a flowable state is put, and uses this state to produce the Hollow block artificial stones are made by adding to the formation of the Cavities for this. required cores in this state and thus sunk effortlessly into the mass will.
Erfindungsgemäß wird bei der Herstellung von Hohlblock-Kunststeinen demnach folgendermaßen verfahren: In einen den Außenabmessungen des herzustellenden Röhlings entsprechenden Formkasten wird das Rohgut eingefüllt und in diesem Formkasten durch von außen her wirkende, zwei= oder dreidimensionale, hochfrequente Schwingungen in den fließfähigen Zustand versetzt. Während dieser Sch-,vingungsbehandlung werden von der offenen Seite des Formkastens her die die Höhlung des Rohlings ergebenden Kerne in das Rohgut eingesenkt, nach Beendigung der Vorschubbewegung der Kerne die Schwingungsbehandlung beendet, danach die Kerne aus dem Rohling herausgezogen und der Rohling aus dem Formkasten entnommen.According to the invention in the production of hollow block artificial stones proceed as follows: In one of the outer dimensions of the one to be manufactured Röhling's corresponding molding box is filled with the raw material and placed in this molding box by two = or three-dimensional, high-frequency vibrations acting from the outside put in the flowable state. During this vibration treatment, be from the open side of the molding box, the resulting cavity of the blank Cores sunk into the raw material, after completion of the feed movement of the cores Vibration treatment ended, then the cores pulled out of the blank and the blank is removed from the molding box.
Die eingangs geschilderten, bei den bisher üblichen Herstellungsmethoden solcher Steine auftretenden Schwierigkeiten, insbesondere die Gefahr ungenügender Festigkeit, besonders bei dünnwandigen--Hohlblocksteinen, wird auf diese Weise zuverlässig vermieden. Der hergestellte Rohling ist bei Anwendung des erfindungsgemäßen Verfahrens unmittelbar nach seiner Herstellung ausreichend verdichtet, so daß er genügend Eigenfestigkeit besitzt, um sofort nach seiner Herstellung dem Formleasten entnommen werden zu können, wodurch erhebliche fertigungstechnische Vorteile hinsichtlich der Herstellungszeit des Rohlings erzielt werden.The above-mentioned, with the production methods customary up to now such stones encountered difficulties, especially the risk of insufficient Strength, especially with thin-walled hollow blocks, is reliable in this way avoided. The blank produced is when the method according to the invention is used Sufficiently compacted immediately after its manufacture, so that it has sufficient inherent strength in order to be able to be removed from the formleate immediately after its production, thereby significant manufacturing advantages in terms of manufacturing time of the blank can be achieved.
