Description

Platte insbesondere Wärmedämmplatte Plate in particular thermal insulation plate

und Verfahren sowie Mittel zu ihrer Herstellung Die Erfindung betrifft eine ;Platte insbesondere Wärmedämmplatte auf der Basis von organischer zähharter Schaumkunststoffe und Verfahren sowie Mittel zu ihrer Herstellung, Zwecks Befestigung von Dämmplatten dieser Art zwischen Dachraven verschiedener Breitenabstände durch Selbstklemmung sind Platten bekannt, die aus wenigstens zwei Teilen mit Nut und Feder zusammengesetzt sind. Zwischen dem Nutboden und Federkante ist dabei ein federndes Teil vorgesehen, so daß die Platten beim Zusammendrücken elastisch nachgeben und dabei ihre Gesamtbreite den jeweiligen Dachravenabständen anzupassen ist. and methods and means for their preparation. The invention relates to a; plate in particular thermal insulation plate on the basis of organic tough-hard Foam plastics and processes and means for their production, for fastening purposes of insulation boards of this type between roof ravines of different widths Self-clamping plates are known that consist of at least two parts with a groove and Spring are composed. There is a resilient one between the groove bottom and the tongue edge Part provided so that the plates yield elastically when pressed together and while their total width is to be adapted to the respective roof rave spacing.

Diese Platten zu verbessern und den Federweg in einfacher Weise zu vergrönern ist die Aufgabe der Erfindung.These plates improve and the spring deflection in a simple manner The object of the invention is to make it bigger.

Diese wird dadurch gelöst, daß die Platte oder wenigstens ein Abschnitt derselben mit in parallelen Abständen voneinander entweder in einer oder beiden Plattenhauptrichtungen verlaufenden ein elastisches Zusammendrücken quer zu ihrer Erstreckung ermöglichenden Höhlräumen versehen sind.This is achieved in that the plate or at least a section same with at parallel distances from each other in either one or both Main plate directions run an elastic compression transversely to their extension allowing cavities are provided.

Die erfindungsgemäßen Platten sind trotz ihrer an sich spröden'und harten Stoffbeschaffenheit überraschend elastisch und können in unerwartet weitem Maße z.B.In spite of their inherently brittle properties, the panels according to the invention are hard fabric texture surprisingly elastic and can be used in an unexpectedly wide range Dimensions e.g.

den unterschiedlichsten Ravenabständen angepaßt werden und erübrigen die Lagerhaltung einer großen Zahl Platten.can be adapted to the most varied of Raven distances and are superfluous the storage of a large number of panels.

mit in verschiedener Breite abgestuften Abmessungen.with dimensions graduated in different widths.

Durch die erfindungsgemäßen Platten wird außerdem etwa 1/3 der Kunststoffmasse ohne Herabsetzung der Dämmeigenschaften der Platten eingespart.The plates according to the invention also make about 1/3 of the plastic mass saved without reducing the insulation properties of the panels.

Ausgestaltungen der Erfindung sind in den Unteransprüchen 2 - 10 beschrieben.Refinements of the invention are described in subclaims 2-10.

Die erfindungsgemäße Platte kann man in vielfältiger Weise herstellen.The plate according to the invention can be produced in a variety of ways.

Erfindungsgemäß kann man das Ausgangsmaterial in Plattenformen mit die Hohlräume aussparenden Ziehkernen eingießen oder einspritzen und nach Erstarren desselben die Kerne sodann freimachen und herausziehen.According to the invention, the starting material can be used in plate forms Pour or inject the drawing cores that are not hollowed out and after solidification then free the kernels of the same and pull them out.

Auch kann man z.B. die Konturen der Hohlräume durch erhitzte Drähte freischmelzen und sodann die ausgeschnittenen Teile ausstoßen.You can also e.g. the contours of the cavities by means of heated wires melt free and then eject the cut-out parts.

In den Unteransprüchen sind beispielsweise Arbeitsmittel zur Durchführung des erstgenannten Verfahrens aufgeführt.In the subclaims, for example, work equipment for implementation of the first-mentioned procedure.

Die Erfindung ist in der Zeichnung an Hand von einigen Ausführungsarten der Platten erläutert.The invention is shown in the drawing on the basis of some embodiments the panels explained.

Es zeigen: Fig. 1 - 4 eine Plattenausführung gemäß der Erfindung; Fig. 5 eine schematische Anordnung erfindungsgemäßer Platten bei einem Schrägdach.1-4 show a panel design according to the invention; 5 shows a schematic arrangement of panels according to the invention on a pitched roof.

In den Fig. 1 - 4 sind aus zähhartem Styropor hergestellte Platten 1 und 5 mit Hohlräumen 2 versehen.In Figs. 1 - 4 are made of tough styrofoam plates 1 and 5 provided with cavities 2.

In der Ausführungsart gemäß Fig. 1 weisen die Hohlräume 2 einen runden Querschnitt auf uns sind reihenweise versetzt angeordnet.In the embodiment according to FIG. 1, the cavities 2 have a round one Cross-section on us are arranged in rows offset.

Beim Zusammendrücken der Platte in Richtung der Pfeile a - b geben die Wände der Hohlräume 2 nach und es tritt unter Verformung der runden Hohlräume 2 zu solchen mit ovalem Querschnitt eine Stauchung ein. Nach Entlastung federn die gestauchten Plattenabschnitte wieder elastisch in die Anfangslage zurück. Eine bleibende Verformung durch zurückbleibende Eigenspannungen tritt hierbei so nicht auf. Man kann die Platten praktisch so lange ohne eine solche Stauchen, bis die Hohlräume verschlossen sind.While squeezing the plate, give in the direction of arrows a - b the walls of the cavities 2 after and it occurs with deformation of the round cavities 2 to those with an oval cross-section a compression. After relieving the pressure, they spring compressed plate sections back elastically to the initial position. A permanent one Deformation due to residual internal stresses does not occur in this way. Man the panels can practically so long without such upsetting until the cavities are locked.

Natürlich kann man die Platten auch entsprechend dehnen.Of course you can also stretch the plates accordingly.

Die Figuren 2 und 3 zeigen weitere Querschnittsformen der Hohlräume.Figures 2 and 3 show further cross-sectional shapes of the cavities.

Eine hiervon unterschiedliche Wirkung wird durch die Hohlräume und Plattenverformungen gemäß Fig. 4 erreicht.A different effect is created by the cavities and Plate deformations according to FIG. 4 achieved.

Hier sind e-f8rmig Hohlräume 7-11 geschaffen, in deren Spalte 9 und nutenartigen Hohlräume 8 federartige Vorsprünge S hineinragen. Die äußeren Hohlräume 7 sind wie die ihnen gegenüberliegenden Oberschichtabschnitte 6 der Platte 5 konkav geformt.Here e-shaped cavities 7-11 are created, in their column 9 and groove-like cavities 8 spring-like projections S protrude. The outer cavities 7, like the top layer sections 6 of the plate 5 opposite them, are concave shaped.

Beim Zusammendrücken der Platte 5 faltet sich der dazwischenliegende Wandabschnitt 12 nach innen und die Vorsprünge 9 dringen in die Hohlräume 8 ein. Durch Letztere erhält die Platte 5 eine Versteifung gegen Verbiegen.When the plate 5 is compressed, the one in between folds Wall section 12 inwards and the projections 9 penetrate into the cavities 8. The latter gives the plate 5 a stiffening against bending.

In Fig. 5 ist eine erfindungsgemäße Platte 13 mit Hohlräumen 14 zu sehen, die mit ihren für Sparren 12 ausgesparten Eckabschnitten 15 diese von unten und seitlich umfassen und die, wie durch Pfeil 16 veranschaulicht, mit Stoßpressung aneinandergefügt sind. Zu diesem Zweck sind auch in den entsprechenden Plattenabschnitten Hohlräume 14a vorgesehen.In FIG. 5, a plate 13 according to the invention with cavities 14 is closed see those with their 12 recessed for rafters Corner sections 15 embrace these from below and from the side and, as illustrated by arrow 16, are joined together with butt pressure. For this purpose are also in the appropriate Plate sections provided cavities 14a.

Die Verfahren und Rezepturen zur Herstellung derartiger Platten sind hinlänglich bekannt, so daß deren weitere Beschreibung entbehrlich ist. Hier daher nur soviel: Die Styroporplatten 1 - 5 werden nach herausziehen der natürlich an der anderen Seite nur bis nahe zum Rand sich erstreckenden Ziehkerne zweckmäßig an der Ziehseite mit einem Styroporrand versehen, so daß die Hohlräume 2 und 7'- 11 vollkommen abgeschlossen sind, wodurch die Dämmeigenschaften der Platten bei geringstem Materialeinsatz wesentlich verbessert werden. Andererseits wird die für Gebäude oft erwünschte Wasserdampfdurchlässigkeit erhöht.The procedures and recipes for making such panels are well known, so that further description is unnecessary. Hence here just this much: The styrofoam sheets 1 - 5 will naturally turn on after you pull them out the other side only useful draw cores extending close to the edge provided with a polystyrene edge on the pull side so that the cavities 2 and 7'- 11 are completely completed, which contributes to the insulating properties of the panels the least amount of material can be significantly improved. On the other hand, the for Buildings often increase the desired water vapor permeability.
