Abstract
Eine Platte auf der Basis zähharter Schaumkunststoffe ist mit in parallelen Abständen zueinander angeordneten Hohlräumen versehen, die ein elastisches Zusammendrücken quer zu ihrer Erstreckung ermöglichen.A plate based on tough foam plastics is provided with cavities which are arranged parallel to one another and which allow elastic compression transversely to their extension.
Description
Die Erfindung betrifft eine Dämmplatte zum Einbau zwischen Dachsparren auf der Basis von organischen Schaumkunststoffen mit in Abständen voneinander in mindestens einer Plattenrichtung verlaufenden, ein elastisches Zusammendrücken quer zu ihrer Längserstrekkung ermöglichenden, zueinander etwa parallelen Ausnehmungen und Verfahren sowie Arbeitsmittel zur Durchführung des Verfahrens.The invention relates to an insulation board for installation between rafters on the basis of organic Foam plastics with spaced apart in at least one panel direction, an elastic one Recesses which are approximately parallel to one another and which enable compression transversely to their longitudinal extension and procedures as well as work equipment for carrying out the procedure.
Durch das DE-GM 80 26 343 ist eine Platte dieser Art bekannt, die mindestens in einem Abschnitt mit in Abständen voneinander in mindestens einer Plattenrichtung verlaufenden, etwa parallelen offenen Ausnehmungen versehen ist Die Ausnehmungen bestehen hierbei aus an zwei parallelen Plattenrändern vorgesehenen im Verhältnis zur Plattendicke dünne Rippen bildenden Längsnute;;. Die naturgemäß eine verhältnismäßig geringe Dicke aufweisenden Rippen biegen sich beim von unten vorzunehmendem Einschieben der Platten nach unten um und sollen sich durch Verhaken an den Dachsparren festsetzen. Da die Abstände der Dachsparren jedoch sehr unterschiedlich sein können, müßte man die Tiefe der Längsnuten bzw. -rippen dementsprechend zweckmäßigerweise an Ort und Stelle bestimmen, was aber kaum möglich sein dürfte. Daher wird der angestrebte fest elastische Sitz nur bei einem Teil der verlegten Platten vorhanden sein, während ein großer Teil locker eingepaßt ist und sich insbesondere bei Temperatureinwirkung lösen kann. Auch können die Rippen beim Einfügen leicht abbrechen und den Halt der Platten beeinträchtigen.From DE-GM 80 26 343 a plate of this type is known, which at least in a section with at intervals approximately parallel open recesses extending from one another in at least one plate direction The recesses consist of two parallel plate edges provided in the In relation to the panel thickness, longitudinal grooves that form thin ribs ;;. Naturally a relatively small one Thick ribs bend when the panels are pushed in from below down and should get stuck on the rafters. As the spacing of the rafters However, the depth of the longitudinal grooves or ribs would have to be accordingly expediently determine on the spot, but this should hardly be possible. Hence, the sought-after firm elastic fit only be present in part of the laid panels, while a large part fits loosely and can come loose, especially when exposed to temperature. Also can the ribs Break off easily when inserting and impair the hold of the panels.
Durch das Herausfräsen der Aussparungen wird außerdem ein Teil des eingesetzten Materials verschwendet. Ferner bilden die Ausnehmungen zwischen den umgebogenen Rippen bei den verlegten Platten mit der Umluft in Verbindung stehende und daher die Dampfsperre sowie die Isolierwirkung teilweise wieder aufhebende Schwachstellen.Milling out the recesses also wastes some of the material used. Furthermore, the recesses between the bent ribs form with the laid panels with the Circulating air connected and therefore partially canceling the vapor barrier and the insulating effect Weak points.
Der Erfindung liegt demgegenüber die Aufgabe zugrunde, eine Dachdämmplatte der eingangs genannten Art bei Einsparung von Material so auszubilden, daß diese mit stabilerem elastischen Sitz zwischen den Dachsparren einzupassen und in größeren Serien vorfertigbar sind und außerdem gute Isoliereigenschaften bei größtmöglicher Dampfdichtigkeit aufweisen.The invention is based on the object of providing a roof insulation panel of the type mentioned at the beginning Kind of saving material in such a way that it has a more stable elastic fit between the Rafters to fit in and can be prefabricated in larger series and also have good insulating properties with the greatest possible vapor tightness.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Ausnehmungen als zu den Plattenhauptoberflächen hin geschlossene Hohlräume ausgebildet sind, die sich mit ihren Hauptabmessungen in beide Plattenhauptrichtungen erstrecken.This object is achieved according to the invention in that the recesses act as the main plate surfaces towards closed cavities are formed, the main dimensions of which are in both plate main directions extend.
Die erfindungsgemäßen Platten sind trotz ihrer an sich spröden und harten Stoffbeschaffenheit überraschend elastisch und können in unerwartet weitem Maße, z. B. den unterschiedlichsten Sparrenabständen angepaßt werden und erübrigen die Lagerhaltung einer großen Zahl Platten mit in verschiedener Breite abgestuften Abmessungen. Durch die erfindungsgemäßenThe panels according to the invention are surprising despite their inherently brittle and hard material properties elastic and can to an unexpectedly wide extent, z. B. adapted to a wide variety of rafter spacing and make it unnecessary to keep a large number of plates with different widths in stock Dimensions. By the invention
Platten wird außerdem etwa V3 der Kunststoffmasse ohne Herabsetzung der Dämmeigenschaften der Platten eingespartIn addition, about V 3 of the plastic compound is saved on panels without reducing the insulating properties of the panels
Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen 2 bis 8 beschrieben.Advantageous embodiments of the invention are described in subclaims 2 to 8.
Erfindungsgemäß wird bei einem Verfahren zur Herstellung der Platten das Ausgangsmaierial in Plattenformen mit die Hohlräume aussparenden Ziehkernen eingegossen oder eingespritzt, und nach Erstarren desselben werden die Kerne sodann freigemacht und herausgezogen. Ein weiteres Verfahren zur Herstellung von Platten ist dadurch gekennzeichnet, daß die Konturen der Hohlräume durch erhitzte Drähte freigeschmolzen und sodann die ausgeschnittenen Teile ausgestoßen werden.According to the invention, in a method for producing the plates, the starting material is in plate forms cast or injected with draw cores leaving out the cavities, and after the same has solidified the cores are then freed and pulled out. Another method of making Plate is characterized in that the contours of the cavities are melted free by heated wires and then the cut-out parts are ejected.
Arbeitsmittel zur Durchführung des erstgenannten Verfahrens sind Gegenstand der Ansprüche 11 bis 13.Work equipment for carrying out the first-mentioned method is the subject of claims 11 to 13.
Die Erfindung ist in der Zeichnung an Hand von einigen Ausführungsarten der Platten erläutert.The invention is explained in the drawing with reference to some embodiments of the plates.

F i g. 1 bis 4 eine Plattenausführung gemäß der Erfindung; F i g. 1 to 4 show a plate design according to the invention;
Fig.5 eine schematische Anordnung erfindungsgemäßer Platten bei einem Schrägdach.5 shows a schematic arrangement of panels according to the invention on a pitched roof.
In den Fig. 1 bis4 sind aus zähhartem Styropor hergestellte Platten 1 bis 5 mit Hohlräumen 2 versehen. In der Ausführungsart gemäß Fig. 1 weisen die Hohlräume 2 einen runden Querschnitt auf und sind reihenweise versetzt angeordnet1 to 4 are made of tough styrofoam Plates 1 to 5 are provided with cavities 2. In the embodiment according to FIG. 1, the cavities have 2 have a round cross-section and are arranged offset in rows
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 Ausgangslage zurück. Eine bleibende Verformung durch zurückbleibende Eigenspannungen tritt hierbei so nicht auf. Man kann die Platte praktisch in solchem Maße stauchen, bis die Hohlräume verschlossen sind. Natürlich kann man die Platte auch entsprechend dehnen.When the plate is pressed together in the direction of the arrows a, b , the walls of the cavities 2 give way and a compression occurs with deformation of the round cavities 2 into those with an oval cross-section. After the load is removed, the compressed plate sections spring back elastically into their original position. Permanent deformation due to residual internal stresses does not occur in this way. The plate can practically be compressed to such an extent that the cavities are closed. Of course, you can also stretch the plate accordingly.
Die F i g. 2 und 3 zeigen weitere Querschnittsformen der Hohlräume.The F i g. 2 and 3 show further cross-sectional shapes of the cavities.
Eine hiervon unterschiedliche Wirkung wird durch die Hohlräume und Plattenverformung gemäß Fig.4 erreicht. Hier sind E-förmige Hohlräume 7 bis 11 geschaffen, in deren Spalte 9 und nutenartige Hohlräume 8 federartige Vorsprünge 10 hineinragen. Die äußeren Hohlräume 7 sind wie die ihnen gegenüberliegenden Oberschichtabschnitte 6 der Platten 5 konkav geformt.A different effect is created by the cavities and plate deformation according to FIG achieved. E-shaped cavities 7 to 11 are created here, 9 and groove-like cavities 8 in their gaps spring-like projections 10 protrude. The outer cavities 7 are like those opposite them Upper layer sections 6 of the plates 5 are concave in shape.
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. In F i g. 5 ist eine erfindungsgemäße Platte 13 mit Hohlräumen 14 dargestellt, 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. t>oWhen the plate 5 is compressed, the intermediate wall section 12 folds inward and the projections 9 penetrate into the cavities 8. The latter gives the plate 5 a stiffening against bending. In Fig. 5, a plate 13 according to the invention is shown with cavities 14 with their for rafters 12 recessed corner sections 15 encompass 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 corresponding plate sections Cavities 14a are provided. t> o
Beim Herstellen der Platten kann wie folgt verfahren werden:When making the panels, you can proceed as follows:
Die Platten 1 bzw. 5, z. B. aus Styropor, werden nach dem Herausziehen der natürlich an der anderen Seite nur bis nahe zum Rand sich erstreckenden Ziehkerne b5 zweckmäßig an der Ziehseite mit einem Styroporrand versehen, so daß die Hohlräume 2 und 7 bis 11 vollkommen abgeschlossen sind, wodurch die Dämmeigenschaften der Platten bei geringstem Materialeinsatz wesentlich verbessert werden.The plates 1 and 5, e.g. B. made of styrofoam, are after pulling out the draw cores b5, which naturally only extend up to the edge on the other side expediently provided with a polystyrene edge on the pull side so that the cavities 2 and 7 to 11 are completely are completed, which means that the insulation properties of the panels are essential with the least amount of material used be improved.
