Abstract

The panel has a rectangular front and rear frames into which cross members can be slid above each other carrying spaced moulding bodies extending in one plane from the front to the rear cross member. PreF. glass fibre covered frames are positioned around the hexagonal moulding bodies (which can be staggered to form a honeycomb) and after the resin impregnated glass fibre has set the moulting bodies can be removed. The number of frames used determines the length of the panel.

Description

??Vorrichtung zur Herstellung von glasfaserverstärkten Kunststoffplatten" Glasfaserverstärkte Kunststoffplatten haben im Schiffs- und Booibau sowie in der allgemeinen Bautechnik weitgehend Eingang gefunden, da sie sehr leicht und preiswert sind und außerdem über gute Isolationseigenschaften in schalltechnischer und temperaturmäßiger Hinsicht verfügen.?? Device for the production of glass fiber reinforced plastic panels " Glass fiber reinforced plastic sheets are used in shipbuilding and booibau as well as in the general construction technology has largely found its way, as it is very light and inexpensive and also have good insulation properties in terms of sound and temperature Respect.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zur Herstellung von glasfaserverstärkten Kunststoffplatten zu schaffen, welche in einfacher Weise aufgebaut und zu handhaben ist, sowie in ve#rgleichsweise schneller Zeit in jeder gewünschten Abmessung herstellbar ist.The invention is based on the object of a device for production of glass fiber reinforced plastic sheets to create which in a simple manner is set up and manageable, as well as in a comparatively quick time in each desired dimension can be produced.

Gemäß, der Erfindung wird dies dadurch erreicht, daß die Vorrichtung einen etwa rechteckförmigen vorderen und hinteren Rah men aufweist, in denen Quertraversen verschiebbar angeordnet sind, welche sich übereinander befinden und mehreren, mit Spiel nebeneinander angebrachte Formkörper tragen, die sich in einer Ebene von der vorderen zu der hinteren Quertraverse ecstrecken.According to the invention this is achieved in that the device has an approximately rectangular front and rear frame in which cross members are arranged displaceably, which are one above the other and several with game Carry attached molded bodies that are in a Stretch the level from the front to the rear cross member.

Die in einen Rahmen eingespannten Glasfasern werden rauch ihrer Tränkung mit Kunststoff auf die Formkörper aufgeschoben, woraufhin die Quertraversen gegeneinander gefahren werden, so daß sich die Glasfasern um die Formkörper legen und nach Aushärtung die gewünschte Form annehmen. Die Rahmen werden dann auseinandergezogen, woraufhin die Formkörper aus der fertigen Platte entfernt werden können.The glass fibers clamped in a frame are smoke from their impregnation with plastic pushed onto the molded body, whereupon the cross members against each other be driven so that the glass fibers wrap around the molded body and after curing take on the shape you want. The frames are then pulled apart, whereupon the moldings can be removed from the finished panel.

Nach einem weiteren Merkmal der Erfindung sind die Formkörper auf den Quertraversen jeweils versetzt zueinander angeordnet und besitzen vorzugsweise etwa sechseckförmigen Querschnitt. Durch diese Anordnung auf Lücke wird beim Zusammenfahren der Quertraversen mit ihren Formkörpern eine Platte erhalten, welche etwa wabenförmigen Querschnitt besitzt. Eine derart gestaltete Platte ergibt eine gute Isolationswirkung und eignet sich außerdem bevorzugt für die Anwendung im Schiffs- und Bootsbau, da eine derartige Platte über eine hohe Stabilität verfügt und außerdem sehr leicht ist.According to a further feature of the invention, the moldings are on the crossbars are arranged offset to one another and preferably have approximately hexagonal cross-section. This arrangement on gap is when driving together the crossbars with their molded bodies receive a plate which is approximately honeycomb-shaped Has cross-section. A plate designed in this way gives a good insulating effect and is also particularly suitable for use in shipbuilding and boat building, there such a plate has a high stability and is also very light is.

Die auf die Formkörper aufschiebbaren Glasfasergewebe sind vorzugsweise in Rahmen eingespannt, und zwar über Kreuz diagonal verlaufend, so daß sich eine feste Verankerung ergibt. Die Rahmen selbst sind nachgiebig gehal#ten, so daß beim Ineinanderfahren der. Quertraversen mit den Formkörpern ein sattes Anliegen der Glasfasern um die Formkörper herum gewährleistet ist.The glass fiber fabrics which can be pushed onto the molded bodies are preferred clamped in a frame, diagonally running crosswise, so that a solid anchoring results. The frames themselves are held resiliently so that the Intertwining of the. Cross members with the molded bodies a full concern of the Glass fibers around the molded body is guaranteed.

Die Anzahl der mit Glasfasern bespannten Rahmen bestimmt die Länge der herzustellenden Platten, d.h. daß nach Entfernen des vorderen oder hinteren Rahmens und Abnehmen der entsprechenden Quertraversen soviel Rahmen mit eingespannten Glasfasern aufgeschoben werden, wie hinterher die Länge der herzustellenden Platten betragen soll.The number of frames covered with fiberglass determines the length of the panels to be produced, i.e. after removing the front or rear Frame and remove the corresponding crossbars as much frame with clamped Glass fibers are pushed on, as is the length of the panels to be produced afterwards should be.

Es ist auch möglich,#anstelle der bespannten Rahmen entsprechend der Anordnung der Formkörper gewebte Glasfasermatten od.dgl.It is also possible to use # instead of the covered frame according to the Arrangement of the molded body woven glass fiber mats or the like.

Ein Ausführungsbeispiel der Erfindung ist an Hand der Zeiinung näher erläutert, und zwar zeigt: Fig. 1 in schematischer Darstellung teilweise dge erfindungsgemäße Vorrichtung in Ansicht mit auseinander gezogenen Formkörpern, Fig. 2 die gleiche Darstellung, jedochmit zusammen; gefahrenen Formkörpern und Fig. 3 in schematischer Darstellung die-wabenförmige Platte.An embodiment of the invention is shown in more detail with reference to the drawing explained, namely shows: FIG. 1 in a schematic representation partly according to the invention Device in view with shaped bodies drawn apart, FIG. 2 the same Representation, but together with; driven moldings and FIG. 3 in a schematic Representation of the honeycomb plate.

Mit 1 ist der vordere und hintere Rahmen bezeichnet, in welchen die Quertraversen verschiebbar angeordnet sind, und zwar aufeinander zu. Die Quertraversen selbst sind übereinander angeordnet und tragen Formkörper 4 mit sechseckigem Querschnitt. Die Formkörper 4 sind gegeneinander versetzt angeordnet, d.h.With 1 the front and rear frame is referred to, in which the Cross members are arranged displaceably, towards one another. The crossbars themselves are arranged one above the other and carry molded bodies 4 with a hexagonal cross-section. the Moldings 4 are arranged offset from one another, i.e.

auf Lücke. Nachdem der vordere oder hintere Rahmen i abgezogen ist und die entsprechenden Quertraversen ebenfalls entfernt sind" können Rahmen mit Glasfasern 2, 3 über die Form körper 4 geschoben werden. Die Glasfasern 2, 3 werden vorzugsweise diagonal in die Rahmen eingespannt und verlaufen über Kreuz, so daß sich eine feste Verankerung ergibt. Die Rahmen für die Aufnahme der Glasfasern 2, 3 sind nachgiebig gestaltet, so daß die Fäden 2, 3 ihre Lage ändern können.on gap. After the front or rear frame i is removed and the corresponding crossbars are also removed "can frame with Glass fibers 2, 3 are pushed over the molded body 4. The glass fibers 2, 3 are preferably clamped diagonally in the frame and run crosswise so that a firm anchorage results. The frames for receiving the glass fibers 2, 3 are designed to be flexible so that the threads 2, 3 can change their position.

Wie in Fig. 2 dargestelltvistt werden nach Aufbringung der einzelnen Rahmen mit den Glasfasern 2, 3 und deren Tränkung mit Kunststoff die Quertraversen 5 zur Mitte hin gegeneinandergefahren, so daß die Fasern 2, 3 um die Formkörper 4 herumliegen. Nach Aushärtung des Kunststoffes werden die Rahmen 1 wieder auseinandergefahren und die Quertraversen entfernt, so dß die Formkörper aus der nunmehr fertigen Platte, wie sie in Fig. 3 dargestellt ist1 herausgezogen werden können. Diese Platte besitzt wabenförmige Kanäle, wobei die Länge sowie Breite und Höhe beliebig sind.As shown in Fig. 2 are vistt after application of the individual Frame with the glass fibers 2, 3 and their impregnation with plastic, the crossbars 5 moved towards each other towards the center, so that the fibers 2, 3 around the molded body 4 lying around. After the plastic has hardened, the frames 1 are moved apart again and the cross members removed, so that the moldings from the now finished plate, as shown in Fig. 3 can be pulled out. This plate owns honeycomb channels, the length as well as width and height are arbitrary.

Derartige Platten sind sehr leicht und stabil, wobei sie außerdem über vorzügliche Isiationseigenschaften verfügen.Such plates are very light and stable, and they also have excellent insulation properties.
