Das Verfahren wird in der folgenden Weise ausgeführt :
Die Gittereinlage e wire mit den Abstandssgliedern f auf den Boden b des Presskaatens a gestellt, worauf das Korkklein o lose eingefüllt und der Deckel aufgesetzt wird, der alsdann unter genügenden Druck gebracht wird. Unter dem Einnusse des Druckes verringert sich das Pressgut o stark an Volumen. wobei das Schwinden des Kork1cleînes bis zu einem Verhältnis von etwa 10 zu 1 erfolgen kann. Nachdem die genügende Pressung erzielt ist, wird der Deckel d durch die Stifte gesichert.
EMI2.1
hindurchtritt und sich nach Massgabe des abnehmenden Volumens gleichmässig ober-und unterhalb der Einlage verteilt.
Sie fiillt auch die unmittelbar unterhalb der Gitterstabe befindlichen Räume vollkommen dicht aus.
Wenn zu Beginn des Arbeitsvorganges zuerst eine Schicht von Korkklein in die Pressform eingefüllt, die Verstärkungseinlage e zusammen mit den Abstandsgliedern f auf diese Schichte aufgesetzt und dann die Form vollkommen gefüllt wird, so berühren die Abstands lieder f den Boden der Form zunächst nicht. Während des Pressens verschiebt sich jedoch die Einlage samt den Abstandsgliedern nach unten, bis diese auf dem Boden der Pressform ruhen und dadurch die Verschiebung der Eionlage begrenzen. Während des fortschreitenden Pressvorganges erfüllen sodann die Abstandsglieder ihre Aufgabe in derselben Weise, wie wenn sie gleich zu Beginn auf dem Boden der Pressform gesetzt worden wären.
Es ist daher ohneweiters möglich, die Verstäkrkungseinlage samt den Abstandsgliedem in beliebiger Höhe innerhalb der unteren Hälfte der Korkmasse einzubetten, ohne dass befürchtet werden muss, dass eine zu grosse oder eine unregelmässige Verschiebung der Einlage stattfindet.
Selbstverständlich können auf dieselbe Weise Presskörper erzeugt werden, bei denen die Verstärkungseinlage sich nicht in der Mitte der Höhe, sondern in der Nähe der oberen oder unteren Fläche der Platte befindet ; es braucht bloss die Höhe oder Länge der Abstandsglieder f entsprechend gewählt zu werden.
Die noch in der Form befindliche gepresste Platte wird der bekannten Weiterlehandlung,

auszuhalten.
Im Eisenbetonbau werden Organe, weiche die Armierungseisen in der richtigen Lage festhalten, seit langem verwendet. Bei Betonkörpers liegen aber die Verhältnisse insofern anders

The procedure is carried out in the following way:
The lattice insert e wire with the spacers f is placed on the bottom b of the press box a, whereupon the cork o is loosely filled and the lid is put on, which is then brought under sufficient pressure. Under the influence of the pressure, the volume of the material to be pressed is reduced significantly. the shrinkage of the cork can be up to a ratio of about 10 to 1. After the sufficient pressure has been achieved, the cover d is secured by the pins.
EMI2.1
passes through and is evenly distributed above and below the insert in accordance with the decreasing volume.
It also fills the spaces immediately below the bars completely tightly.
If at the beginning of the work process a layer of cork is first filled into the mold, the reinforcement insert e is placed on this layer together with the spacers f and the mold is then completely filled, the spacing members f do not initially touch the bottom of the mold. During the pressing process, however, the insert moves down together with the spacers until they rest on the bottom of the mold and thereby limit the movement of the egg layer. As the pressing process continues, the spacers then fulfill their task in the same way as if they had been placed on the bottom of the mold right at the start.
It is therefore possible in any case to embed the reinforcing insert including the spacers at any height within the lower half of the cork mass, without having to fear that the insert will shift too much or be irregular.
Of course, compacts can be produced in the same way in which the reinforcing insert is not in the middle of the height, but near the upper or lower surface of the plate; only the height or length of the spacers f needs to be selected accordingly.
The pressed plate that is still in the mold is passed on to the known

to endure.
In reinforced concrete construction, organs that hold the reinforcing iron in the correct position have been used for a long time. In the case of concrete bodies, however, the situation is different
