Die Vorsprünge 11 erstrecken sich im Winkel von 90° zur jeweiligen Längsseite des plattenförmigen Bereichs 2. Die Vorsprünge 11 weisen in dem von der Längsseite des plattenförmigen Bereichs 2 abgewandten Bereich rechteckige Positionierungsschlitze 12 auf. Die Positionierungsschlitze 12 verlaufen parallel zur Längsseite des plattenförmigen Bereichs 2. Durch die Ausstanzung des Positionierungsschlitzes 12 entsteht an dem dem plattenförmigen Bereich zugewandten Rand des Positionierungsschlitzes 12 eine Sollbiegestelle 14, die ein Ende eines Halteabschnitts 13 bildet, der sich bis zum freien Ende des Vorsprungs 11 erstreckt.The in Fig. 1 and on an enlarged scale in Fig. 2 shown blank 1 for the in Fig. 3 shown flexible sheet plate is formed by a stamped part of sheet metal and comprises a rectangular, plate-shaped portion 2 with two opposite longitudinal sides, of which in each case a plurality of spaced-apart rectangular tab-shaped projections 11 extend outwardly. The projections 11 extend at an angle of 90 ° to the respective longitudinal side of the plate-shaped portion 2. The projections 11 are in the of the longitudinal side of the plate-shaped portion 2 facing away from rectangular positioning slots 12. The positioning slots 12 are parallel to the longitudinal side of the plate-shaped portion 2. By punching the positioning slot 12 is formed on the plate-shaped portion facing edge of the positioning slot 12 a predetermined bending point 14 which forms one end of a holding portion 13 which extends to the free end of the projection 11th extends.

Von einigen der Vorsprünge 11 erstrecken sich an einer Längsseite des Vorsprungs 11 im Winkel von 90° zum Vorsprung 11 abstehende Laschen 15. Durch eine Ausstanzung 16 im Übergangsbereich zwischen Vorsprung 11 und Lasche 15 entsteht eine weitere Sollbiegestelle 19. Weiter weisen einige der Vorsprünge 11 Bohrungen 17 auf. Zur besseren Anschaulichkeit zeigen Fig. 1 und Fig. 2 mehrere gestrichelte Linien 18, 201, an denen der Zuschnitt 1 im Verlauf der Herstellung abgekantet wird.From some of the projections 11 extend on a longitudinal side of the projection 11 at an angle of 90 ° to the projection 11 projecting tabs 15. By a punch 16 in the transition region between the projection 11 and tab 15 creates a further predetermined bending point 19. Next, some of the projections 11 holes 17 on.

Fig. 3 und Fig. 4 zeigen eine aus dem Zuschnitt 1 durch Abkanten an den Abkantlinien 18, 201 und den Sollbiegestellen 14, 19 hergestellte Bogenplatte 10. Die Vorsprünge 11 sind an der Abkantlinie 18 im Winkel von 90° zur Oberfläche der Bogenplatte 10 nach oben gebogen. Wie es in Fig. 1 zu erkennen ist, verläuft die Abkantlinie 18 in geringem Abstand zur Längsseite des plattenförmigen Bereichs 22, so dass sich nach der Abkantung ein schmaler Rand 3 zwischen den Vorsprüngen 11 und der Oberfläche des plattenförmigen Bereichs 2 über die gesamte Längsseite erstreckt, wie es Fig. 4 zeigt. Der Rand 3 dient der Stabilität der Bogenplatte 10. Die Halteabschnitte 13 ihrerseits wurden wiederum im Winkel von 90° zu den Vorsprüngen 11 um die Sollbiegestelle 14 gebogen und verlaufen parallel zur Oberfläche der Bogenplatte 10. FIG. 3 and FIG. 4 show an out of the blank 1 by folding at the Abkantlinien 18, 201 and the predetermined bending points 14, 19 produced sheet plate 10. The projections 11 are bent at the Abkantlinie 18 at an angle of 90 ° to the surface of the sheet plate 10 upwards. As it is in Fig. 1 can be seen, the Abkantlinie 18 extends at a small distance to the longitudinal side of the plate-shaped portion 22, so that after bending a narrow edge 3 between the projections 11 and the surface of the plate-shaped portion 2 extends over the entire longitudinal side, as it Fig. 4 shows. The edge 3 serves the stability of the sheet plate 10. The holding portions 13 in turn were in turn bent at an angle of 90 ° to the projections 11 around the predetermined bending point 14 and extend parallel to the surface of the sheet plate 10th

Die Laschen 15 zur Fixierung eines Seitensegments 30 an die Bogenplatte 10 sind um die Sollbiegestelle 19 gebogen und erstrecken sich nach innen über die Bogenplatte 10. Die Randabschnitte 20 an den Querseiten der Bogenplatte 10 sind in einem Winkel von 90° zur Oberfläche der Bogenplatte 10 an einer Abkantung 201 von der Bogenplatte 10 weg nach oben gebogen.The tabs 15 for fixing a side segment 30 to the sheet plate 10 are bent around the predetermined bending point 19 and extend inwardly over the sheet plate 10. The edge portions 20 on the transverse sides of the sheet plate 10 are at an angle of 90 ° to the surface of the sheet plate 10 at a fold 201 bent away from the sheet plate 10 upwards.

Fig. 5 und in vergrößertem Maßstab Fig. 6 zeigen ein längliches, gekrümmtes Seitensegment 30 aus einem Stanzteil aus Blech, das einen oberen, konvex gekrümmten Längsrand 34 und einen unteren, konkav gekrümmten Längsrand 35 aufweist, die parallel zueinander verlaufen. Von dem oberen Längsrand 34 erstrecken sich Positionierungsnasen 31 nach oben, die in Anzahl, Abstand und Form an die Positionierungsschlitze 12 der Vorsprünge 11 angepasst sind und die, bei der Herstellung des Bauelements, in die Positionierungsschlitze 12 der Bogenplatte 10 formschlüssig eingreifen. Des Weiteren weisen die Seitensegmente 30 Öffnungen 32 auf, die in Anzahl, Abstand und Form an die Laschen 15 der Vorsprünge 11 angepasst sind. Durch die Öffnungen 32 werden bei der Herstellung des Bauelements die Laschen 15 hindurchgeführt und hiermit die Bogenplatte 10 an das Seitensegment 30 fixiert. Außerdem sind an dem Seitensegment 30 Bohrungen 33 ausgebildet, die mit den Bohrungen 17 der Vorsprünge 11 fluchten. Zur Befestigung einer Sichtblende 40 geht durch diese Bohrungen 17, 33 ein sich von der Sichtblende 40 erstreckender Gewindestift 41 hindurch. Fig. 5 and on an enlarged scale Fig. 6 show an elongated, curved side segment 30 of a stamped part made of sheet metal, which has an upper, convexly curved longitudinal edge 34 and a lower, concavely curved longitudinal edge 35 which extend parallel to each other. From the upper longitudinal edge 34 extending positioning lugs 31 which are adapted in number, spacing and shape to the positioning slots 12 of the projections 11 and which engage in the production of the device in the positioning slots 12 of the sheet plate 10 positively. Furthermore, the side segments 30 openings 32, which are adapted in number, spacing and shape of the tabs 15 of the projections 11. Through the openings 32, the tabs 15 are passed in the manufacture of the component and thus the sheet plate 10 fixed to the side segment 30. In addition, 30 holes 33 are formed on the side segment, which are aligned with the bores 17 of the projections 11. To attach a screen 40 goes through these holes 17, 33 a extending from the screen 40 threaded pin 41 therethrough.

Aus einer fertig ausgestanzten und abgekanteten Bogenplatte 10, wie in Fig. 3 gezeigt, und einem in Längsrichtung biegestabilen Seitensegment 30, wie in Fig. 5 gezeigt, lässt sich ein konkav gekrümmtes Bauelement, wie in Fig. 7 gezeigt, herstellen. Dazu wird die gestanzte und abgekantete Bogenplatte 10 mit der Sichtseite auf eine plane Unterlage gelegt. Wenn die Bogenplatte 10 eine Perforation aufweist, kann bereits jetzt auf der Innenseite ein Akustikvlies oder andere akustische Dämmmaterialien befestigt werden.From a finished punched and folded sheet plate 10, as in Fig. 3 and a longitudinally flexurally stable side segment 30, as shown in FIG Fig. 5 can be shown, a concave curved component, as in Fig. 7 shown, manufacture. For this purpose, the punched and folded sheet plate 10 is placed with the visible side on a flat surface. If the arcuate plate 10 has a perforation, an acoustic fleece or other acoustic insulation materials can already be fastened on the inside.

Das in Längsrichtung biegestabile Seitensegment 30 wird innenseitig mit der flächigen Seite in die Bogenplatte 10 gelegt, bis es am Rand 3 der Bogenplatte 10 in einem Eckbereich der Bogenplatte 10 anliegt. Der untere Längsrand 35 des Seitensegments 30 liegt dabei an der Innenseite des Randes 3 der Bogenplatte 10 an. Um das Seitensegment 30 in Längsrichtung zu fixieren, wird das Seitensegment im Winkel von 90° zur Oberfläche der Bogenplatte 10 eingedreht und verläuft nun parallel zu den Vorsprüngen 11, wodurch die erste, im Winkel von 90° zu den Vorsprüngen 11 abstehende Lasche 15 durch die Öffnung 32 des Seitensegments 30 gesteckt wird. Nun greifen die ersten Positionierungsnasen 31 des Seitensegments 30 in die Positionierungsschlitze 12 der Bogenplatte 10 ein. Durch das Biegen der Bogenplatte 10 greifen nun weitere Positionierungsnasen 31 des Seitensegments 30 in die Positionierungsschlitze 12 der Vorsprünge 11 ein und rasten ein. Durch weiteres Biegen der Bogenplatte 10 fixieren zusätzliche Laschen 15 an den Vorsprüngen 11 die Bogenplatte 10 in Längsrichtung an das Seitensegment 30. Dadurch nimmt die biegsame Bogenplatte 10 die Form des biegestabilen Seitensegments 30 an und es entsteht ein gekrümmtes Bauelement.The longitudinally bending-stable side segment 30 is placed on the inside with the flat side in the sheet plate 10 until it rests against the edge 3 of the sheet plate 10 in a corner region of the sheet plate 10. The lower longitudinal edge 35 of the side segment 30 rests against the inside of the edge 3 of the sheet plate 10. In order to fix the side segment 30 in the longitudinal direction, the side segment is screwed in at an angle of 90 ° to the surface of the sheet plate 10 and now runs parallel to the projections 11, whereby the first, projecting at an angle of 90 ° to the projections 11 tab 15 through the Opening 32 of the side segment 30 is inserted. Now, the first positioning lugs 31 of the side segment 30 engage in the positioning slots 12 of the sheet plate 10. By bending the sheet plate 10 now engage more positioning lugs 31 of the side segment 30 in the positioning slots 12 of the projections 11 and engage. By further bending the sheet plate 10, additional tabs 15 on the projections 11 fix the sheet plate 10 longitudinally to the side segment 30. Thus, the flexible sheet plate 10 assumes the shape of the bending stable side segment 30 and a curved component is formed.

Ein endgültiges Fixieren der Bogenplatte 10 an das Seitensegment 30 wird, wie in Fig. 8 und Fig. 9 gezeigt, durch das Umbiegen der Halteabschnitte 13 um eine Sollbiegelinie erreicht, die durch den Rand der Positionierschlitze 12 gebildet wird, der dem freien Ende der Halteabschnitte 13 zugewandt ist. Die Halteabschnitte 13 werden zur Oberfläche der Bogenplatten 10 hin gebogen und umgreifen somit den oberen Längsrand des Seitensegments 30. Die Bogenplatte 10 liegt an dem unteren Längsrand des Seitensegments 30 an.A final fixing of the sheet plate 10 to the side segment 30, as in Fig. 8 and Fig. 9 shown achieved by the bending of the holding portions 13 to a predetermined bending line, which is formed by the edge of the positioning slots 12 which faces the free end of the holding portions 13. The holding portions 13 are bent towards the surface of the sheet plates 10 and thus surround the upper longitudinal edge of the side segment 30. The sheet plate 10 abuts against the lower longitudinal edge of the side segment 30.

Analog zum Einsetzen und Fixieren des ersten Seitensegments 30 kann ein zweites Seitensegment 30 am gegenüberliegenden Rand der Bogenplatte 10 eingesetzt und fixiert werden.Analogous to the insertion and fixing of the first side segment 30, a second side segment 30 can be inserted and fixed on the opposite edge of the sheet plate 10.

Die Gewindestifte 41 der Sichtblende 40 werden durch die fluchtenden Bohrungen 17, 33 der Bogenplatte 10 und der Seitensegmente 30 gesteckt (siehe Pfeile in Fig. 7). Ein Eckbereich des fertigen Bauelements von Fig. 7 ist nach dem Anbringen der Sichtleiste in vergrößertem Maßstab in Fig. 10 gezeigt. Hier ist die Sichtblende 40 durch die Gewindestifte 41 innenseitig mit einer Schraubenmutter 42 am Bauelement fixiert.Next shows Fig. 7 a concave curved component before mounting a screen 40. The screws 41 of the screen 40 are inserted through the aligned holes 17, 33 of the sheet plate 10 and the side segments 30 (see arrows in FIG Fig. 7 ). A corner of the finished component of Fig. 7 is in an enlarged scale after attaching the view bar Fig. 10 shown. Here, the screen 40 is fixed by the threaded pins 41 on the inside with a nut 42 on the component.

In einer nicht gezeigten Ausführungsform kann durch die Bohrungen 17, 33 der Bogenplatte 10 und des Seitensegments 30 ein Befestigungselement gesteckt werden, so dass zwei und mehr baugleiche, oder auch formverschiedene Bauelemente miteinander verbunden und modularisiert werden können.In one embodiment, not shown, a fastening element can be inserted through the holes 17, 33 of the sheet plate 10 and the side segment 30, so that two or more identical, or even different shape components can be interconnected and modularized.
