Bei dieser Montage müssen vor allem die Stellung des oder der Anbauteile an dem dafür vorgesehenen Platz kontrolliert, die Fixierungsleisten oder Rückwände auf mit dem Gestell verbundenen Trägerteilen angebracht und die Verbindungsstellen zwischen jedem Anbauteil und seinem Trägerteil verkittet werden. Selbstverständlich ist eine solche Montage in mehreren einzelnen Stufen sowohl an der Arbeitsstelle als auch in der Halle besonders zeitraubend und schwierig und kann nur von qualifizierten Arbeitskräften, im Falle der Montage an der Arbeitsetelle auoh häufig nur unter gefährlichen Bedingungen vorgenommen werden.have to. During this assembly, the position of the attachment (s) on the intended Controlled space, the fixing strips or rear panels on support parts connected to the frame attached and the junctions between each Attachment and its carrier part are cemented. It goes without saying that such an assembly takes place in several individual parts Steps both at the workplace and in the hall are particularly time-consuming and difficult and only can by qualified workers, in the case of assembly at the work site, too, often only under dangerous conditions Conditions are made.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, bei einem neuen Verfahren zur Herstellung von Rahmen oder Grundgeetellen aus Kunststoffen diese Nach» teile zu vermeiden«The present invention is based on the object in the case of a new process for the production of frames or basic frames made of plastics, this parts to avoid «

Fig. 1 bis 4 zeigen sohematisoh die verschiedenen Verfahr ensstufen einer Ausführungsform des erfindüngs-* gemäßen τerfahrene.Further details and special features of the method according to the invention emerge from the following description and the accompanying drawing. Figs. 1 to 4 also show the various methods steps of an embodiment of the invention * according to τexperienced.

In einer unteren Halbform 1 wird ein mit zwei Glasfasermatten 3 und 4 umhüllter Kern 2 aus wärmeisolierendem Material angeordnet. Die Matten werden mitIn a lower half-mold 1 is one with two Glass fiber mats 3 and 4 covered core 2 made of heat-insulating Material arranged. The mats come with

Hierauf wird die untere HaIlDform 1 mit dem Kern 2, den Matten 3 und 4 und den Kanten des Anbauteils 8, mit der oberen Halbform 9 geschlossen. Attachment 8, e.g. a double window or a plate, is placed. Then the lower half shape 1 with the Core 2, the mats 3 and 4 and the edges of the attachment 8, with the upper half-mold 9 closed.

In der fertigen Form kann jetzt das Gestell oder der Rahmen gegossen werden. Der ausreichend fließfähige, d.h. bei entsprechender Temperatur - im Falle des PoIyesterβ bei etwa 600O - gehaltene Kunststoff wird unter Druck durch einen Kanal 10 injiziert, verteilt sich in dem freien Innenraum der Hohlform, durchtränkt die Glasfasern 3 und 4 und umhüllt den Kern 2 und die Kanten des Anbauteiles 8, die in die Hohlform hineinragen.In the finished form, the frame or the frame can now be poured. The sufficiently flowable, ie at the appropriate temperature - in the case of polyester at about 60 0 O - is injected under pressure through a channel 10, is distributed in the free interior of the hollow mold, soaks the glass fibers 3 and 4 and envelops the core 2 and the edges of the attachment 8, which protrude into the hollow shape.

Der in die Hohlform injizierte Kunststoff wird weiter erhitzt, um ihn auszupolymerisieren und auszuhärten. Polyester wird auf eine Temperatur von 12O0C gebracht; bei dieser Temperatur härtet er vollständig aus.The plastic injected into the hollow mold is heated further in order to polymerize and harden it. Polyester is brought to a temperature of 12O 0 C; at this temperature it hardens completely.

Das auspolymerisierte und ausgehärtete Grundgestell bzw. der Rahmen wird entformt, indem die obere Halbform 9 abgenommen und der Formkörper aus der unteren Halbform 1 herausgenommen wird»The fully polymerized and cured base frame or the frame is demolded by the upper half-mold 9 is removed and the molded body is removed from the lower half-mold 1 »

Bei dem erfindungsgemäß hergestellten Grundgestell oder Rahmen ist das Anbauteil 8 mit seinen Kanten fest in der Kunststoffmasse eingebettet.In the case of the base frame produced according to the invention or frame, the attachment 8 is firmly embedded with its edges in the plastic compound.
