Description

Steinholzverbundplatte Die Erfindung betrifft eine Verbundplatte aus Steinholz und Zementbeton, besonders für Fußbodenbelag. Die bekannten Platten dieser Art haben den Nachteil, daß sie-sich infolge der beim Abbindevorgang von Steinholz auftretenden starken Raumänderung der Stein= holzmasse 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 besteht aus zwei gleichen und. gleich starken Außenschichten aus Steinholz und einer diese verbindenden zweckmäßig stärkeren Zwischenschicht aus Zementbeton. Bei der Herstellung der Platte werden die einzelnen Schichten in erdfeuchtem Zustande in eine Form eingebracht und durch kurzen hydraulischen Druck zusammengepreßt.Stone wood composite panel The invention relates to a composite panel made of Stone wood and cement concrete, especially for flooring. The well-known panels of this Kind have the disadvantage that they are due to the setting process of stone wood Occurring strong change in space of the stone = wood mass and the resulting easily throw large tensile stresses and crack. This applies to the new one Plate because of its peculiar structure. The plate according to the invention consists of two equal and. equally thick outer layers of stone wood and one these connecting appropriately stronger intermediate layer of cement concrete. In the In the manufacture of the plate, the individual layers are in an earth-moist state introduced a mold and pressed together by brief hydraulic pressure.

Die genannten Eigenschaften des Steinholzes haben bisher die Herstellung einer Verbundplatte aus Steinholz und Zementbeton erschwert, da es nötig war, den Preßdruck während des Abbindevorganges aufrechtzuerhalten, um ein Reißen und Werfen der Platte zu verhüten.The mentioned properties of the stone wood have so far been responsible for the production a composite panel made of stone wood and cement concrete made it difficult because it was necessary to Maintain pressure during the setting process to prevent tearing and throwing to prevent the plate.

In der Zeichnung ist die neue Verbundplatte beispielsweise im Schnitt dargestellt, und zwar sind mit a der mittlere, verhältnismäßig starke Kern oder die Zwischenschicht aus Zementbeton oder ähnlicher Masse, mit b und b' die gleichartigen und gleich starken -Außenschichten aus Steinholz bezeichnet.In the drawing, for example, the new composite panel is in section shown, namely with a the middle, relatively strong core or the intermediate layer of cement concrete or similar mass, with b and b 'the same and equally thick outer layers of stone wood.

Bei der Herstellung der Verbundplatte nach der Erfindung wird in eine Preßform zunächst -eine dünne Steinholzschicht im erdfeuchten Zustande eingebracht, auf diese dann eine stärkere Zementbetonschicht 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 vollkommen gleicht, damit beim Abbinden der Schichten an den Berührungsflächen mit der Betonschicht möglichst die gleichen Oberflächenspannungen auftreten. Nach dem Auffüllen der Formen in der beschriebenen Weise werden diese einem kurzen Preßdruck ausgesetzt, dann aber aus der Presse entfernt und zum Abbinden beiseitegestellt.In the manufacture of the composite panel according to the invention is in a Press mold first - a thin layer of stone wood introduced in the earth-moist state, A thicker cement-concrete layer is then applied to this and then through a top layer of stone wood, which is also earth-damp, is covered. It must be on it Care must be taken that the underlayer is made of stone wood in terms of strength and composition completely resembles the top layer, so when the layers set on the contact surfaces If possible, the same surface tensions occur with the concrete layer. To the filling of the forms in the manner described, these are a short pressure exposed, but then removed from the press and set aside to set.
