Description
Steinholzverbundplatte und Verfahren zur Herstellung derselben. Die Erfindung betrifft eine Verbundplatte aus Steinholz und Zementbeton, zum Beispiel für Fussbodenbelag. Die bekannten Platten dieser Art haben den Nachteil, dass sie sich infolge der beim Abbindevorgang von Stein holz auftretenden starken Raumänderung der Steinholzmasse und der hierdurch erzeugten grossen Zugspannungen leicht werfen und Risse bekommen. Dies trifft bei der neuen Platte wegen ihres eigenartigen Aufbaues nicht ein. Die Platte nach der Erfindung be steht aus zwei gleichen und gleich starken Aussenschichten aus Steinholz und einer diese verbindenden, zweckmässig stärkeren Zwi schenschicht aus Zementbeton.
Bei der Her stellung der Platte werden zweckmässig die einzelnen Schichten in erdfeuchtem Zustande in eine Form gebracht und durch kurzen Druck durch eine hydraulische Presse zu sammengepresst.
In der Zeichnung ist die neue Verbund platte beispielsweise im Schnitt dargestellt, und zwar sind mnit cc der mittlere, verhältnis- mässig starke Kern oder die Zwischenschicht aus Zementbeton, mit b und bi gleiche und gleich starke Aussenschichten aus Steinholz bezeichnet.
Bei der Herstellung der Verbundplatte wird vorzugsweise in eine Pressforni zunächst eine dünne Steinholzschicht im erdfeuchten Zustande eingebracht, auf diese dann eine stärkere Zeinentbetonschicht aufgetragen und diese hierauf durch eine Oberschicht aus gleichfalls erdfeuchtem Steinholz abgedeckt.
Dabei muss darauf geachtet werden, dass die Unterschicht aus Steinholz in Stärke und Zusammensetzung der Oberschicht vollkom inen gleicht, damit beim Abbinden der Sehfich ten an den Berührungsflächen mit der Beton schicht möglichst die gleichen Oberflächen- spannungen auftreten. Nach dem der Formen in der beschriebenen Weise wer den diese einem kurzen Pressdruck durch eine hydraulische Presse ausgesetzt, dann aber aus der Presse entfernt und zum Ab binden beiseite gestellt.
Stone wood composite panel and method of making the same. The invention relates to a composite panel made of stone wood and cement concrete, for example for floor coverings. The known panels of this type have the disadvantage that they easily throw themselves and get cracks due to the large change in space of the stone wood mass that occurs during the setting process of stone wood and the large tensile stresses generated thereby. This does not apply to the new plate because of its peculiar structure. The plate according to the invention consists of two identical and equally strong outer layers of stone wood and a connecting, suitably stronger inter mediate layer of cement concrete.
In the manufacture of the plate, the individual layers are expediently brought into a form in a moist state and pressed together by a hydraulic press with brief pressure.
In the drawing, the new composite panel is shown, for example, in section, namely with cc the middle, relatively strong core or the intermediate layer of cement concrete, with b and bi the same and equally thick outer layers of stone wood.
During the production of the composite panel, a thin layer of stone wood in the earth-moist state is preferably first introduced into a press mold, then a thicker cementitious concrete layer is applied to this and this is then covered by a top layer of equally earth-moist stone wood.
Care must be taken to ensure that the stonewood lower layer is completely identical in thickness and composition to the upper layer, so that the same surface tensions occur as far as possible when the visual layers on the contact surfaces with the concrete layer set. After the forms in the manner described who these exposed to a brief pressure by a hydraulic press, but then removed from the press and set aside to bind from.
