Description
Holzwolle-Leichtbauplatten nach DIN 1101 werden u.a. sehr häufig als verlorene Schalung verwendet. Zu diesem Zweck werden sie beim Betonieren auf die Schalung gelegt, wobei dann der frische Beton in die Poren der Platte eindringt und eine innige Verbindung zwischen Beton und Platte herstellt. Wood wool lightweight panels according to DIN 1101 are, among other things, very often used as permanent formwork. To this end they are placed on the formwork during concreting, with the fresh concrete then penetrating the pores of the slab and creates an intimate connection between the concrete and the slab.
In vielen Fällen wird die Holzwolle-Leichtbauplatte auf der Raumseite der Wand oder der Decke anschließend nicht verputzt, sondern lediglich mit Farbe gestrichen oder gespritzt, so daß die poröse Struktur der Plattenoberfläche erhalten bleibt. Dies geschieht vor allen Dingen dann, wenn die schallschluckenden Eigenschaften der Holzwolle-Leichtbauplatten ausgenützt werden sollen.In many cases, the wood wool lightweight panel on the room side of the wall or ceiling is not subsequently plastered, but simply painted or sprayed with paint, so that the porous structure of the plate surface preserved. This happens above all when the sound-absorbing properties of the wood wool lightweight panels should be exploited.

Eine große Schwierigkeit ergibt sich bei der Herstellung von Decken oder Wänden, weil beim Betonieren sogenannte Zementmilch durch die Plattenfugen oder durch die Platte tis auf die Sichtseite dringt, die schallschluckende Wirkung der Platte aufhebt und zudem noch unschöne Flecken in der Struktur der Platte bildet. Das Durchlaufen der Betonmilch an den Plattenstößen wird dadurch verhindert, daß man die Plattenstöße von oben her mit einem geeigneten Klebeband abklebt. Für die Plattenfläche selbst gab es bisher kein sicheres Mittel, das Durchlaufen der Zementmilch zu verhindern, vor allen Dingen dann, wenn aus irgendwelchen Gründen der Beton in relativ flüssiger Konsistenz eingebracht werden mußte.A great difficulty arises in the production of ceilings or walls, because so-called when concreting Cement milk penetrates through the tile joints or through the tile tis on the visible side, the sound-absorbing effect the plate picks up and also forms unsightly spots in the structure of the plate. Going through the Concrete milk on the plate joints is prevented by opening the plate joints from above with a suitable Masking tape. Until now there was no safe means for the surface of the slab itself, namely the passage of the cement milk to prevent, above all, if for some reason the concrete has a relatively liquid consistency had to be brought in.
Aufgabe der Erfindung ist es, diesen Nachteil zu beseitigen. Neuerungsgemäß wird bei einer Holzwolle-Leichtbauplatte mit Einlage in Vorschlag gebracht, daß parallel zu ihren beiden Oberflächen in das Innere der Platte eine dünne Schicht aus geeignetem Material (Papier, Folie usw.) bei der maschinellen Herstellung eingearbeitet ist, welche das Durchlaufen von Zementbrühe beim Betonieren durch die Platte verhindert. Diese Schicht kann aus Natron-Kraft-Papier, Bitumen-Papier, Kunststoff-Folie bestehen und mit oder ohne Vorbehandlung durch geeignete Kleber eingebracht werden. Beim Einbau dieser Platten kann die Zementmilch dann nur noch bis zu dieserThe object of the invention is to eliminate this disadvantage. According to the innovation, with a wood wool lightweight panel with Inlay put in proposal that parallel to its two surfaces in the interior of the plate made a thin layer suitable material (paper, foil, etc.) is incorporated into the machine production, which the passing through of cement broth when concreting is prevented by the slab. This layer can be made of soda kraft paper, bitumen paper, Plastic sheeting is made and can be applied with or without pretreatment using a suitable adhesive. When installing this The cement milk can then only slab up to this

remain.
In der Zeichnung ist die neuerungsgemäße Holzwolle-Leichtbauplatte schematisch veranschaulicht. Diese besteht aus den beiden Holzwolleschichten 1 und 2, zwischen denen eine dünne Folie 3 eingearbeitet ist, welche das Durchdringen der Flüssigkeit verhindert.In the drawing is the wood wool lightweight board in accordance with the innovation illustrated schematically. This consists of the two wood wool layers 1 and 2, between which a thin film 3 is incorporated, which prevents the penetration of the liquid.
