Description

Die vorliegende Erfindung bezieht sich auf ein Verfahren zur Herstellung einer Bauplatte des Holzwollezementtyps unter Zusammendrücken durch Preßdruck in einer Richtung, wobei in der Bauplatte Kanäle mittels in geringen gegenseitigen Abständen vorgesehener Kerne ausgespart werden, welche im Querschnitt eine derartige Form aufweisen, daß sich der Raum zwischen zwei benachbarten Kernen von der Ober- und Unterseite dieser Kerne nach deren Mitte hin regelmäßig verringert.The present invention relates to a method of manufacture a building board of the wood wool cement type under compression by pressing pressure in one direction, whereby in the building board channels by means of in low mutual Distances provided cores are left out, which in cross section such Have a shape that the space between two adjacent cores extends from the upper and the underside of these nuclei regularly decreased towards their center.

Das erfindungsgemäße Verfahren unterscheidet sich von den bekannten Verfahren, bei denen Kerne mit Vorsprüngen verwendet werden, dadurch, daß Kerne mit glatt verlaufender Außenbegrenzung benutzt werden, und zwar derart, daß durch Zusammenwirken des Preßdrucks und der Mäterialkerne außer in der Preßrichtung auch in einer quer dazu und zu der Längsrichtung der Kerne stehenden Richtung ein Zusammendrücken bewirkt wird.The method according to the invention differs from the known Process in which cores with protrusions are used, in that cores be used with a smooth outer boundary, in such a way that through Cooperation of the pressing pressure and the material cores apart from in the pressing direction as well compression in a direction transverse to this and to the longitudinal direction of the cores is effected.

Das Material wird also zweiseitig verdichtet.The material is compressed on both sides.

Bei Anwendung der Erfindung wird, gegenüber Platten mit Kanälen, bei denen der erfindungsgemäße Effekt nicht erhalten worden ist, in den Räumen zwischen den Kernen verhältnismäßig etwas mehr Material benutzt, insgesamt aber wird weniger gebraucht, als für eine Massivplatte derselben Abmessung nötig wäre.When applying the invention, compared to plates with channels, at which the effect of the invention has not been obtained in the spaces between relatively more material is used for the cores, but less is overall used than would be necessary for a solid sheet of the same dimensions.

Die Festigkeit der Bauplattenteile zwischen den Kanälen oder Kernen wird jedoch bedeutend größer, so daß auch die Festigkeit der ganzen Platte vergrößert wird.The strength of the building board parts between the channels or cores however, it becomes significantly larger, so that the strength of the entire plate is also increased will.

Es wird bemerkt, daß Bauplatten mit Kanälen der Art, auf welche sich die Erfindung bezieht, jedoch mit wenigstens einer Verstärkungsschicht bekleidet, an sich bekannt sind; diese Platten werden aber nicht unter Zusammendrücken des Materials hergestellt, wenn auch das Pressen von Platten des Holzwollezementtyps bekannt ist.It is noted that building panels with channels of the type in which the invention relates, but covered with at least one reinforcement layer, are known per se; however, these plates are not compressed by compressing the Material produced, albeit the pressing of boards of the wood wool cement type is known.

Die Erfindung wird nachstehend unter Hinweis auf die Zeichnung erläutert. Darin zeigt Fig. i eine Vorderansicht einer Bauplatte mit ausgesparten Kanälen, Fig. 2 einen Querschnitt gemäß der Linie II-II in Fig. i und Fig. 3 in vergrößertem Maßstab einen Querschnitt der Platte im Herstellungsstadium.The invention is explained below with reference to the drawing. FIG. 1 shows a front view of a building board with recessed channels, Fig. 2 shows a cross section along the line II-II in Fig. I and Fig. 3 in an enlarged Scale a cross-section of the plate in the manufacturing stage.

Die aus Holzwollezement angefertigte Bauplatte i nach den Fig. i und 2 ist mit Längskanälen 2 und Nuten 3 versehen.The construction panel made of wood wool cement i according to FIGS. I and 2 is provided with longitudinal channels 2 and 3 grooves.

Die Herstellung der Platte geht wie folgt vor sich: Nachdem (s. Fig. 3) Rohre 4 in der Form angeordnet sind, wird der um diese Rohre gelegte Holzwollezement 7 zusammengedrückt, und zwar gleichzeitig von oben her durch die Platte 5 und von unten her durch die Platte 6. Das Material wird beim Zusammendrücken in der Pfeilrichtung gleichfalls zwischen den Rohren 4 verdichtet. Damit das Material richtig gleitet, fettet man die Rohre vorzugsweise ein. Zwischen den Rohren entstehen somit Zonen von großer Festigkeit, die in der Hauptsache I-förmig sind.The plate is manufactured as follows: After (see Fig. 3) Pipes 4 are arranged in the mold, the wood wool cement put around these pipes becomes 7 compressed, at the same time from above through the plate 5 and from down through the plate 6. The material is pressed in the direction of the arrow also compressed between the tubes 4. So that the material glides properly, the pipes are preferably greased. Zones are thus created between the pipes of great strength, which are mainly I-shaped.
