In Fig. 3 ist eine Verbindung zwischen einem Trägerprofil 35 und einer Sandwichverbundplatte 37 detailliert dargestellt. Der geschäumte Kern 32 der Sandwichverbundplatte 37 ist beidseitig mit den Deckblechen 34 beplankt. Die Deckbleche 34 übergreifen das mit den Oberflächen des Kerns 32 fluchtende Anschlussprofil 36 formschlüssig. Die Verbindung zwischen den Deckblechen 34 und dem Kern 32 bzw. dem Anschlussprofil 36 erfolgt über eine zwischenliegende, in der Zeichnung nicht dargestellte Klebstoffschicht.3 shows a connection between a carrier profile 35 and a sandwich composite panel 37 shown in detail. The foamed core 32 of the sandwich composite panel 37 is covered on both sides with the cover plates 34. The cover plates 34 overlap what is aligned with the surfaces of the core 32 Connection profile 36 form-fitting. The connection between the cover plates 34 and the core 32 or the connection profile 36 takes place via an intermediate one, in the drawing adhesive layer, not shown.

Das zum Anschluss an ein Trägerprofil vorgesehene in die Verbundplatte 37 integrierte Anschlussprofil 36 weist einen integralen ersten Auflagestreifen 38 und einen vom Anschlussprofil 36 abragenden zweiten Auflagestreifen 40 auf. Diese beiden Auflagestreifen 38, 40 des Trägerprofils 35 liegen einem entsprechend vom Trägerprofil 35 abragenden ersten Auflagestreifen 42 bzw. einem dem Trägerprofil 35 integral angeformten zweiten Auflagestreifen 44 auf. Die beiden Auflagestreifen 38, 40 am Anschlussprofil 36 sind parallel zueinander und in einem Abstand a angeordnet. Dieser Abstand a entspricht dem Abstand der ebenfalls parallel zueinander liegenden Auflagestreifen 42, 44 am Trägerprofil 35. Die Enden der abragenden Auflagestreifen 40, 42 sind mit dem diesen jeweils anliegenden Auflagestreifen 38, 42 über je eine Hauptschweissnaht 46, 48 durch eine Laserschweissung miteinander verbunden.The one intended for connection to a carrier profile in the composite panel 37 integrated connection profile 36 has one integral first support strip 38 and one of the connection profile 36 protruding second support strip 40. These two contact strips 38, 40 of the carrier profile 35 lie correspondingly protruding from the carrier profile 35 first support strip 42 or one of the carrier profile 35 integrally molded second support strip 44. The are two contact strips 38, 40 on the connection profile 36 arranged parallel to each other and at a distance a. This Distance a corresponds to the distance which is also parallel support strips 42, 44 lying on one another on the carrier profile 35. The ends of the protruding support strips 40, 42 are with the contact strip 38, 42 which is adjacent to each one main welding seam 46, 48 each by laser welding connected with each other.

Die Deckbleche 34 übergreifen teilweise das Anschlussprofil 36 und sind mit ihrer freien Kante über je eine Schweissnaht 50, 52 durch eine Laserschweissung mit dem darunterliegenden Anschlussprofil 36 verbunden.The cover plates 34 partially overlap the connection profile 36 and are with their free edge over a weld seam each 50, 52 by laser welding with the one below Connection profile 36 connected.

Da bei einer Laserschweissung unbedingt vermieden werden muss, dass Klebstoff zur Schweissstelle gelangen kann, müssen im Bereich der Schweissstellen zwischen den Deckblechen 34 und dem darunterliegenden Anschlussprofil 36 entsprechende Vorkehrungen getroffen werden. Diese beinhalten einerseits eine absolute Klebstoffreiheit im Kantenbereich der Deckbleche 34, wobei eine zusätzliche Sicherheit durch eine spezielle Ausbildung des Anschlussprofils 36 im Bereich der Schweissnähte 50, 52 erreicht werden kann. Hierzu sind im Anschlussprofil 36 längslaufende Nuten bzw. querschnittlich U-förmige Längsrinnen 54, 56 als sogenannte Klebstoffallen vorgesehen. Diese bewirken, dass beim Verkleben der Deckbleche 34 mit dem Kern 32 unter Druck ausweichender Klebstoff in der Nut 54, 56 aufgefangen wird und damit nicht in den Bereich der zu erzeugenden Schweissnaht 50, 52 gelangen kann. Durch die Schweissnähte 50, 52 entsteht eine gasdichte Verbindung zwischen den Deckblechen 34 und dem darunterliegenden Anschlussprofil 36, so dass eine Verminderung der Haftfähigkeit zwischen Deckblechen 34 und dem Kern 32 auch nach jahrelanger Betriebszeit ausgeschlossen werden kann.Because laser welding is absolutely to be avoided must that glue can get to the welding point in the area of the welds between the cover plates 34 and the underlying connection profile 36 corresponding Precautions are taken. These include on the one hand, absolute freedom from adhesives in the edge area the cover plates 34, with additional security through a special training of the connection profile 36 in the area the weld seams 50, 52 can be reached. For this are in Connection profile 36 longitudinal grooves or cross-section U-shaped longitudinal channels 54, 56 as so-called adhesive halls intended. These cause the cover sheets to stick together 34 with the core 32 under pressure evasive adhesive is caught in the groove 54, 56 and thus not in the area of the weld seam 50, 52 to be produced. The weld seams 50, 52 create a gas-tight connection between the cover plates 34 and the one below Connection profile 36, so that a reduction in adhesiveness between cover plates 34 and the core 32 also after years of operation can be excluded.

Die dem abragenden Auflagestreifen 52 des Trägerprofils 35 benachbarte Längsnut bzw. U-förmige Längsrinne 56 dient gleichzeitig dem Toleranzausgleich, indem der abragende Auflagestreifen 40 eine grössere Beweglichkeit aufweist und so bei zu hoher Toleranz leicht gegen den entsprechenden Auflagestreifen 44 am Trägerprofil 35 gedrückt bzw. bei zu enger Toleranz leicht gespreizt werden kann.The protruding support strip 52 of the carrier profile 35 adjacent longitudinal groove or U-shaped longitudinal groove 56 is used at the same time the tolerance compensation by the protruding Support strip 40 has greater mobility and so if the tolerance is too high, easily against the corresponding contact strip 44 pressed on the carrier profile 35 or too narrow Tolerance can easily be spread.

Die insbesondere in Fig. 3 im Detail dargestellte Verbindungstechnik ist bei allen Stellen des Wagenkastens 10 anwendbar, bei dem eine Sandwichplatte mit einem längslaufenden Profil verbunden werden muss. Bei der in Fig. 1 dargestellten Ausführungsform eines Wagenkastens 10 sind diejenigen Stellen, bei denen die Verbindungstechnik gemäss Fig. 3 zur Anwendung gelangt, mit x bezeichnet. Die übrigen Verbindungsstellen zwischen dem Uebergangsteil 26 und den Fensterpfosten 28, zwischen den Fensterpfosten 28 und der Seitenwand 20 sowie zwischen dem inneren Längsträger 18 und der inneren Bodenplatte 31, sind genietet.The connection technology shown in detail in particular in FIG. 3 can be used in all places of the body 10, where a sandwich plate with a longitudinal one Profile must be connected. The one shown in Fig. 1 Embodiments of a car body 10 are those Locations where the connection technology according to Fig. 3 used, designated by x. The other connection points between the transition part 26 and the window posts 28, between the window posts 28 and the side wall 20 and between the inner side member 18 and the inner base plate 31 are riveted.

Mit der hier beschriebenen Verbindungstechnik zwischen Sandwichverbundplatten 37 und Trägerprofilen 35 lässt sich der Wagenkasten 10 von Fig. 1 auf einfache Weise dreiteilig vorfertigen und anschliessend durch Einsetzen der Fensterprofile 28 sowie der inneren Bodenplatte 31 endmontieren. Selbstverständlich gilt die hier für den Querschnitt eines Wagenkastens 10 beschriebene Verbindungstechnik auch für die entsprechenden Verbindungen in Wagenlängsrichtung zwischen den Sandwichplatten und zwischengeordneten Querträgern.With the connection technology described here between Sandwich composite panels 37 and carrier profiles 35 can be the car body 10 of FIG. 1 in three parts in a simple manner prefabricate and then by inserting the window profiles 28 and the inner base plate 31.
