Description

Das Bestreben geht seit langem dahin, eine Bauplatte zu finden, die nicht nur gewichtsmäßig leicht ausfällt und leicht herstellbar ist, sondern die auch allen übrigen Anforderungen der Bautechnik entspricht, die also mechanisch relativ hoch @eanspruchbar ist, erreicht durch gute Festigkeitswerte, die große Wärme-und Schalldämmeigenschaften u. dgl. besitzt, und die außerdem tunlichst billig fabriziert werden kann. In dieser Hinsicht lassen aber alle bisher auf dem Markt befindlichen Leichtbauplatten in der einen oder anderen Beziehung mehr oder weniger zu wünschen übrig.The endeavor has long been to find a building board that not only is light in weight and easy to manufacture, but the also corresponds to all other requirements of structural engineering, i.e. mechanical is relatively high @strong, achieved by good strength values, the large Has heat and sound insulation properties and the like, and which are also as cheap as possible can be fabricated. In this regard, however, they have all been on the market so far located lightweight panels in one way or another more or less to be desired.

Eingehende Versuche und Erprobungen haben nun gezeigt, daß man dem gesteckten Ziel bestmöglichst nahekommt mit einer Bauplatte, die erfindungsgemäß in der Weise gefertigt wird, daß man einem Teil in Wasser dünn angerührtem Gips etwa io bis 3o Gewichtsteile eines Harz enthaltenden leichten Füllstoffs zumischt. Als besonders geeigneter Füllstoff hierfür ist zu nennen. Nadelholzsägemehl, das bekanntlich schon an sich harzhaltig ist. Der vorgesehene Harzbestandteil, bevorzugt in einer Menge von bis etwa i°/, Gewichtsanteil des Gipses, auf welchen Bestandteil es hierbei als neu und wesentlich für die gute Abbindung von Gips und Füllmasse ankommt, macht es möglich, daß man ohne Beeinträchtigung der Güte der Platten bzw. zusätzlich zu Nadelholzsägemehl etwa im gleichen gewichtsmäßigen Verhältnis auch eine andere Leichtfüllmasse als Zusatz verwenden kann, z. B. Torfmull, welcher sich hierfür ebenfalls sehr bewährt, wie die Untersuchungen erbrachten.In-depth experiments and trials have now shown that you can as close as possible to the set goal with a building board that, according to the invention is made in such a way that one part in water thinly mixed plaster of paris about 10 to 3o parts by weight of a resin-containing lightweight filler. A particularly suitable filler for this is to be mentioned. Softwood sawdust, that is known to be resinous in itself. The intended resin component, preferred in an amount of up to about 1% by weight of the plaster of paris on which component it is new and essential for the good setting of plaster of paris and filling compound arrives, makes it possible that you can without impairing the quality of the panels or in addition to softwood sawdust in roughly the same weight ratio too can use another light filler as an additive, e.g. B. Peat litter, which also very well proven for this, as the investigations showed.

Das Mischen von Gips und Sägemehl ist an sich zwar schon bekannt. Es hat sich indessen ergeben, daß eine einwandfrei brauchbare und gute Abbindung der beiden genannten Stoffe erst dann gesichert ist, wenn, wie hervorgehoben, Sägemehl von Nadelhölzern verwendet wird, deren Harzgehalt in der erwähnten Weise für die gute Abbindung und die dadurch mitbedingte Festigkeit der Leichtbauplatte wichtig ist; jedenfalls haben Platten, hergestellt unter Verwendung von Sägemehl anderer Holzsorten, festigkeitsmäßig wesentlich ungünstigere Prüfwerte erbracht.Mixing plaster of paris and sawdust is already known per se. It has been found, however, that a perfectly usable and good setting of the two substances mentioned is only secured if, as emphasized, sawdust is used by conifers, the resin content of which in the manner mentioned for the Good setting and the resulting strength of the lightweight panel are important is; in any case, have panels made using sawdust from others Types of wood, test values that are significantly less favorable in terms of strength.

Ein Nachteil der bekannten Gipsplatten liegt nun ferner noch darin, daß sie zu stark aufbrennen, worunter man versteht, daß sie bei nachfolgender Verputzarbeit zu gierig wasseraufsaugend wirken. Auch dieser Mangel ist bei der neuen Platte vermieden, und zwar ebenfalls durch den chemisch wirksam werdenden Harzbestandteil. Günstig wirkt sich in dieser Beziehung ebenfalls auch die Beigabe des schon genannten Torfmulls als Füllstoff aus, der den weiteren Vorzug hat, daß er sich gleichfalls sehr gut in die Plattenmasse einbindet, billig ist und die Platte gewichtsmäßig noch leichter macht. Alle diese genannten Vorzüge sind um so mehr gewährleistet, wenn man dabei noch einen Spezialgips verwendet, der besonders gut gebrannt wird, und zwar bei einer Temperatur bis 220°C, während man sonst hochwertige Gipse in der Regel nur bis Zoo ° brennt.Another disadvantage of the known plasterboard is that that they burn too much, which is understood to mean that they will burn out during subsequent plastering work act too greedy water-absorbent. This defect is also avoided with the new plate, also through the chemically active resin component. Cheap The addition of the peat dust mentioned above also has an effect in this regard as a filler, which has the further advantage that it is also very good binds into the plate mass, is cheap and the plate is even lighter in weight power. All of these benefits are even more guaranteed when you are at it another special plaster of paris is used, which is fired particularly well, namely at a temperature of up to 220 ° C, while otherwise high-quality plasters are usually only available until Zoo ° burns.

Als Herstellungsrezept für die neue Bauplatte ist beispielsweise folgendes zu nennen 4o kg bis 22o° C gebrannter Gips wird in etwa 501 Wasser der Temperatur von 5 bis io° C glatt verrührt. Dieser Masse werden dann etwa 6 kg Nadelholzsägemehl und 5 kg Torfmull beigerührt. Die Masse wird sodann möglichst rasch in Plattenformen, beispielsweise der Größe von 8 x 25 x 5o cm gegossen, in denen sie rasch erstarrt und fest wird.The following is an example of the manufacturing recipe for the new building board to name 4o kg to 22o ° C baked plaster is in about 501 water of the temperature Stirred from 5 to 10 ° C until smooth. This mass then becomes about 6 kg of softwood sawdust and 5 kg of peat waste added. The mass is then as quickly as possible in plate forms, For example, the size of 8 x 25 x 50 cm, in which it solidifies quickly and becomes solid.

Fig. i und 2 zeigen die fertige Form dieser so erhaltenen Platten in schaubildlicher Darstellung und in einer Querschnittsansicht. In letzterer bedeuten dabei schematisiert veranschaulicht die länglichen Teilchen i den Sägemehlbestandteil und die rundlichen Teilchen 2 den Torfmullanteil. 3 und 4 sind Nut und Feder, in denen die Platten zusammengreifend versetzt werden, und 5 sind Haftrillen für einen nachträglichen Verputz der fertig verlegten Wandplatten.Figs. I and 2 show the finished shape of these panels thus obtained in a diagrammatic representation and in a cross-sectional view. In the latter mean the elongated particles i schematically illustrate the sawdust component and the rounded particles 2 the peat waste fraction. 3 and 4 are tongue and groove, in which the panels are offset together, and 5 are adhesive grooves for one Subsequent plastering of the finished wall panels.
