Description

Herstellung einer Leichtbauplatte Die Erfindung betrifft die Herstellung von Leichtbauplatten für Fußböden, Decken, Dächer, Außen- und Innenwände von Wohnhäusern und Arbeitsräumen.Production of a lightweight panel The invention relates to production of lightweight panels for floors, ceilings, roofs, exterior and interior walls of residential buildings and workrooms.

Zur Herstellung der Leichtibauplatten wird langfaserige Holzwolle mit kurzfaserigen Stoffen, wie Sägemehl, Sägespänen oder Hobelspänen, unter Zusatz eines gebräuchlichen anorganischen Bindemittels, wie Zement, Sorelzement od. dgl., vermischt und hierauf geformt und gepreßt.Long-fiber wood wool is used to manufacture the lightweight construction panels with short-fiber materials such as sawdust, sawdust or wood shavings, with additives a common inorganic binder, such as cement, Sorel cement or the like, mixed and then shaped and pressed.

Aus langfaserigem Material (Holzwolle) können zwar Leichtbauplatten hergestellt werden, die jedoch keinen Druck aushalten. Bei Verwendung von kurzfaserigem Material (Sägemehl zu Holzbeton verarbeitet) können nur kleinflächige Körper hergestellt werden, die aber gegen Druck sehr widerstandsfähig sind. Werden beide Materialien unter Verwendung von Bindemitteln zu einer Masse vereint, so lassen sich aus dieser Leichtbaukörper von großem Format und erhöhtem Druckwiderstand herstellen. Zweckmäßig ist es, mehrschichtige Leichtbauplatten herzustellen, deren untere Schicht kurzfaseriges, deren mittlere Schicht langfaseriges und deren obere Schicht wieder kurzfaseriges Material enthält.Lightweight panels can be made of long-fiber material (wood wool) but cannot withstand pressure. When using short fiber Material (sawdust made into wood-concrete) can only be produced with small-area bodies but which are very resistant to pressure. Will both materials combined to form a mass using binders, this can be Manufacture lightweight structures of large format and increased pressure resistance. Appropriate is to produce multi-layer lightweight panels, the lower layer of which is short-fiber, the middle layer is long-fiber and the top layer is again short-fiber Contains material.
