Description

Verfahren zum Verbinden von Kunststoff-Hartschaumplatten an ihren Stoßkanten Die vorliegende Erfindung betrifft ein Verfahren zum Verbinden von Kunststoff-Hartschaumplatten an ihren Stoßkanten bei der Herstellung einer zusammenhängenden Wärme-Isolierschicht.Method for joining rigid plastic foam panels to their Butting edges The present invention relates to a method for joining rigid plastic foam panels at their abutting edges during the production of a coherent heat-insulating layer.

Es ist bekannt, wärmeisolierende Schichten aus Kunststoff-Hartschaum herzustellen. Bei größeren Flächen werden zu diesem Zweck Plattenelemente von handlicher Größe zusammengefügt.It is known to have heat-insulating layers made of rigid plastic foam to manufacture. For larger areas, plate elements are more manageable for this purpose Size joined together.

Hierzu ist bekannt, die Kanten der Platten mit Ausnutungen zu versehen. Darin werden Leisten oder Profile verschiedener Querschnittsform angeordnet, welche die Platten auf irgendeiner Unterlage festhalten.For this purpose, it is known to provide the edges of the plates with grooves. In it strips or profiles of different cross-sectional shape are arranged, which hold the plates on some kind of surface.

Auf diese Weise sind die Platten jedoch nicht fest miteinander verbunden, sondern nur aneinanderliegend auf einer Unterlage befestigt.In this way, however, the panels are not firmly connected to each other, but only attached to one another on a base.

Es ist also immer eine Trage- oder Haltekonstruktion erforderlich.A support or holding structure is therefore always required.

Außerdem bilden die in den Nuten der Plattenkanten befindlichen Leisten oder Profile - die meist aus Metall bestehen - sogenannte Kältebrttcken, das heißt, an diesen Stellen ist die wärmedämmende Wirkung der Isolierschicht erheblich beeinträchtigt. Dies ist ein schwerwiegender Nachteil, der sich nicht nur in einem mehr oder weniger großen Energieverlust äußert; es kommt auch an diesen Kältebrücken zu Schwitzwasserbildungen, die wiederum von den Stoßkanten sich ausbreitend die Wärmedämmfähigkeit der Platten beeinträchtigen. Schließlich ist die Art der Verbindung auch arbeitstechnisch umständlich und teuer. Ein Verkleben der Platten kommt ebenfalls meist aus arbeitstechnischen Gründen nicht in Betracht.In addition, the strips located in the grooves of the panel edges form or profiles - which are mostly made of metal - so-called cold blocks, that is, at these points the insulating effect of the insulating layer is considerably impaired. This is a serious disadvantage that is not only in one expresses a greater or lesser loss of energy; it also occurs at these cold bridges to condensation, which in turn spreads from the abutting edges Impair the thermal insulation properties of the panels. After all, it's the type of connection also labor-technically cumbersome and expensive. The panels are also glued mostly out of consideration for work-related reasons.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren zu schaffen, nach dem auf arbeitstechnisch einfache und damit billige Weise eine feste und dauerhafte Verbindung der Plattenkanten ohne jegliche Bildung von Kältebrücken möglich ist.The present invention is therefore based on the object of a method to create a technically simple and therefore cheap way firm and permanent connection of the panel edges without any formation of cold bridges is possible.

Zur Lösung dieser Aufgabe geht die Erfindung davon aus, daß die Plattenelemente an ihren Kanten mit Ausnutungen versehen werden, so daß jeweils die einander gegenüberliegenden Nuten von zwei aneinanderstoßenden Platten einen seitlich geschlossenen Kanal bilden.To solve this problem, the invention assumes that the plate elements be provided at their edges with grooves, so that each of the opposite Grooves of two abutting plates form a laterally closed channel.

Die gestellte Aufgabe wird erfindungsgemäß dadurch gelöst, daß man diese Kanäle an ihren Enden verschließt, in bestimmten Abständen mit seitlichen Eingieß- oder Einspritzöffnungen versieht und einen gießbaren, zu einem festen Schaumkörper aushärtenden Kunststoff hineinbringt.The object is achieved according to the invention in that closes these channels at their ends, at certain intervals with lateral Provides pouring or injection openings and a pourable, to a solid foam body brings hardening plastic into it.

Die Erfindung ist anhand einer Zeichnung näher erläutert. Es zeigen: Fig. 1 zwei aneinanderstoßende Isolierplatten mit Querschnittsbild, Fig. 2 eine andere Form der Ausnutung und Fig. 3 eine weitere Form der Ausnutung.The invention is explained in more detail with reference to a drawing. Show it: Fig. 1 two abutting insulating plates with a cross-sectional image, Fig. 2 one another form of the recess and FIG. 3 another form of the recess.

Man verlegt die Plattenelemente 1, fixiert sie so, daß sie nicht mehr auseinanderweichen können und bringt das flüssige Schaummaterial durch die dafür vorgesehenen seitlichen Öffnungen 2 in die von den Nuten 3 gebildeten Kanäle. Bei senkrechten Wänden geschieht dies mittels einer geeigneten Spritze. Bei Dachisolierungen kann das Schaummaterial auch eingegossen werden. In den Kanälen bildet sich ein Kunststoff-Hartschaumprofil 4, das die Plattenelemente 1 zusammenhält.The plate elements 1 are laid, they are fixed in such a way that they are no longer can diverge and brings the liquid foam material by the side openings 2 provided for this purpose in those formed by the grooves 3 Channels. In the case of vertical walls, this is done using a suitable syringe. In the case of roof insulation, the foam material can also be poured in. In the canals A rigid plastic foam profile 4 is formed, which holds the plate elements 1 together.

Dieser Zusammenhalt wird sowohl mechanisch durch Verankerung, als auch durch Verklebung des eingeschäumten Profils 4 mit den Platten 1 bewirkt. Je nach den verwendeten Kunststoffen -sowohl für die Platten 1 als auch für die eingeschäumten Profile 4 - kaun die eine oder die andere Haltekraft überwie#en.This cohesion is achieved both mechanically through anchoring also caused by gluing the foamed-in profile 4 to the plates 1. Ever according to the plastics used - both for the plates 1 and for the foamed-in ones Profile 4 - can outweigh one or the other holding force.

Soll die Haltekraft der Verankerung überwiegen, so wählt man eine tiefere Ausnutung ~der Plattenkanten, wobei die Flanken 3a (Fig. 1) der Nuten 3 hinter schnitten sind.If the holding force of the anchoring should predominate, one should choose one deeper groove ~ of the plate edges, the flanks 3a (Fig. 1) of the grooves 3 are behind cuts.

Soll hingegen die Haltekraft der Verklebung überwiegen, so wählt man eine Ausnutung, die eine große Klebefläche ergibt, beispielsweise eine flache, breite Nut, wobei der Grund 5a (Fig. 2) der Nut 5 noch zur Vergrößerung der Oberfläche gewellt oder gerippt ist.If, on the other hand, the holding force of the bond should predominate, then one chooses a recess that gives a large adhesive surface, for example a flat, wide one Groove, the base 5a (Fig. 2) of the groove 5 still to enlarge the surface is corrugated or ribbed.

In Fig. 3 ist eine Ausnutung dargestellt, in der beide Halteskrä te gleichermaßen berücksichtigt sind in der Weise, daß man auf dem Grund einer breiten, flachen Nut 6 noch eine Vertiefung 6a mit hinters c hnittenen Flanken anordnet.In Fig. 3 a recess is shown in which both Halteskrä te are equally taken into account in such a way that on the basis of a broad, flat groove 6 still a recess 6a with rear c hcut flanks.

Eine zusätzliche Verankerung ergeben noch die sich ebenfalls mit Hartschaum ausfüllenden Eingießöffnungen 2.An additional anchoring also results with rigid foam filling pouring openings 2.

Man erhält nach dem erfindungsgemäßen Verfahren eine feste Verbindung der Plattenkanten, die eine in wärmetechnischer Hinsicht praktisch völlig homogene Isolierschicht ergibt und auf einfachste Weise herzustellen ist.A solid connection is obtained by the process according to the invention the panel edges, which are practically completely homogeneous from a thermal point of view Insulating layer results and can be produced in the simplest possible way.
