 erwiesen haben. Nach entsprechender Durchdampfung der Platten, welche bei den Platten mit Rahmen sich auch im Austreten von Dampf durch die Lochungen des Rahmens zeigt, lässt man die Platten abkühlen und austrocknen. Nach dem Austrocknen und Abkühlen zeigen die so behandelten Platten keinerlei Neigung zum Werfen oder zur Blasenbildung an der Oberfläche. Nicht unerwähnt soll bleiben, dass diese Imprägnierung auch die Poren verschliesst, wodurch die Platten auch zur Herstellung von gassicheren bzw. gasundurchlässigen Räumen mit Vorteil verwendet werden können (z. B. auch zur 
 EMI2.1 
 der Platten in Gegenden   zweckmässig   erscheinen, wo bisher derartig einfache Bauweisen unmöglich waren, z.

   B. in tropischen Gegenden und Gegenden mit starken klimatischen Schwankungen, wobei 
 EMI2.2 
 Termiten widerstandfähig sind. 



     PATENT-ANSPRÜCHE   :
1. Verfahren zur Herstellung von   Leichtbauplatten   mit einem Grundkörper aus   Leiehtbau-   stoffen, wie mit Mörtel aller Art gebundener Holzwolle od. dgl. Faserstoff, mit Bitumen gebundenem Korkklein usw. und ein-oder beiderseits aufgeklebten Furnieren, Sperrholzplatten od. dgl., welcher Grundkörper oder die Furniere od. dgl. oder beide mit einer Imprägnierung gegen Feuer oder tierische und pflanzliche Schädlinge versehen wurden, dadurch gekennzeichnet, dass der Grundkörper oder die Furniere oder beide nach der Imprägnierung einer Pressung auf der Heissdampfpresse unterworfen werden, um die Imprägnierung tiefer in das Material eindringen zu lassen und jede Spannung in den einzelnen Schichten zu beseitigen.

 have proven. After appropriate vaporization of the panels, which is also evident in the panels with frames in the escape of steam through the perforations of the frame, the panels are allowed to cool and dry out. After drying and cooling, the plates treated in this way show no tendency to warp or to form bubbles on the surface. It should not go unmentioned that this impregnation also closes the pores, so that the panels can also be used to advantage for the production of gas-safe or gas-impermeable spaces (e.g. also for
 EMI2.1
 the panels appear useful in areas where such simple construction methods were previously impossible, z.

   B. in tropical areas and areas with strong climatic fluctuations, whereby
 EMI2.2
 Termites are resistant.



     PATENT CLAIMS:
1. Process for the production of lightweight panels with a base made of lightweight construction materials, such as wood wool or similar fibrous material bound with mortar of all kinds, cork bound with bitumen, etc. and veneers, plywood panels or the like glued on one or both sides, which base body or the veneers or the like or both have been provided with an impregnation against fire or animal and vegetable pests, characterized in that the base body or the veneers or both are subjected to a pressing on the superheated steam press after the impregnation in order to penetrate the impregnation deeper into the To allow material to penetrate and to remove any tension in the individual layers.

 

Claims (1)

2. Verfahren nach Anspruch 1, dadurch gekennzeichnet, dass die Leichtbauplatten mit einem einen Teil derselben bildenden, zweckmässig aus einzelnen verleimten Leisten bestehenden Rahmen umgeben werden, die vorzugsweise mit durchgehenden Lochungen versehen sind, um bei der Dampfbehandlung Dampf und Feuchtigkeit durchtreten zu lassen. 2. The method according to claim 1, characterized in that the lightweight panels are surrounded by a part of the same forming, expediently consisting of individual glued strips, which are preferably provided with through holes to allow steam and moisture to penetrate during the steam treatment. 3. Verfahren nach den Ansprüchen 1 und 2, dadurch gekennzeichnet, dass die Dampfbehandlung bei hohem Pressdruck (bis 120 Atm. ) und Temperaturen gegen 900 C durch längere Zeit erfolgt. 3. The method according to claims 1 and 2, characterized in that the steam treatment is carried out at high pressure (up to 120 atm.) And temperatures around 900 C for a longer period of time.
