Description
ten Innenmantel 9, Der Hohlraum zwischen Außenmantel 10 und Innenmantel 9 ist zur Aufnahme von Wärroeschutzraaterial eingerichtet. Wie Fig.3 erkennen läßt, wird der Flüssiggasbehälter 7 mit seiner ihn umgebenden Stütz- und Tragkonstruktion 6 vor dem Einbau in den Laderaum 5 zusätzlich mit einem die stark gerundeten Kanten des Behälterbodens umgreifenden und sie abstutzenden, ringförmigen, steifen Unterbau 11 versehen. Der Unterbau 11 ist mit einer derartigen Abmessung versehen, daß der Boden des Flüssiggasbehälters 7 und mit ihm die Stütz- und Tragkonstruktion 6 bei Normaltemperatur durch den ringförmigen, steifen Unterbau 11 in Richtung seiner Ebene so weit zusammengedrückt wird, daß die bei Abkühlung des Flüssiggasbehälters 7 auf Betriebstemperatur auftretende Schrumpfung des Behälterbodens durch die derart aufgebrachte Vorspannung ausgeglichen wird. Um die Vorspannung aufzubringen, ist, wie die Fig.3 erkennen läßt, der steife Unterbau 11 aus vier Seitenstücken Il α bzw. 11 b zusammengesetzt, die im Bereich der Ecken durch Ecksvüclce XXp bzw. 11 q miteinander verbinden sind. Hierzu werden die Seitenstücke Ha1 116 zunächst unter die Stütz- und Tragkonstruktion 6 geschoben und dann mittels geeigneter Druckböcke od. dgl. aufeinander zu gepreßt, so daß sich der Boden des Flüssiggasbehälters 7 durcbwölbt. Nach dem Zusammendrücken der Seitenstücke 11 α, 11 b um das erforderliche Maß werden die Seitenstücke Ha, Ub durch Verschweißen mit den Eckstücken Up und Hq miteinander verbunden. Jedes der Seitenstücke besteht aus einer gekrümmten Schale 12 sowie zugeordneten Stütz- und Versteifungswinkeln 13, die mit ösen 14 zum Einhängen von Seilen 15 versehen sind. Nach Einbau des Flüssiggasbehälters wird zweckmäßig der steife Unterbau 11 mit dem Zwischenboden 3 bzw. den übrigen, den Laderaum 5 begrenzenden Teilen verschweißt.th inner jacket 9, the cavity between the outer jacket 10 and the inner jacket 9 is set up to accommodate heat protection material. As can be seen in FIG. 3, the liquefied gas container 7 with its surrounding support and load-bearing structure 6 is additionally provided with an annular, rigid substructure 11 that encompasses and supports the strongly rounded edges of the container base prior to installation in the cargo space 5. The substructure 11 is provided with such dimensions that the bottom of the liquid gas container 7 and with it the supporting and supporting structure 6 at normal temperature by the annular, rigid substructure 11 in the direction of its plane is so far compressed that the cooling of the liquid gas container 7 Shrinkage of the container bottom occurring at operating temperature is compensated for by the prestress applied in this way. In order to apply the bias, as shown in FIG. 3, the rigid substructure 11 is composed of four side pieces II α and 11 b , which are connected to one another in the area of the corners by Ecksvüclce XXp and 11 q. For this purpose, the side pieces Ha 1 116 are first pushed under the support and load-bearing structure 6 and then pressed towards one another by means of suitable pressure blocks or the like, so that the bottom of the liquid gas container 7 bulges. After the side pieces 11 α, 11 b have been pressed together by the required amount, the side pieces Ha, Ub are connected to one another by welding with the corner pieces Up and Hq. Each of the side pieces consists of a curved shell 12 and associated support and stiffening angles 13, which are provided with eyelets 14 for hanging ropes 15. After the installation of the liquid gas container, the rigid substructure 11 is expediently welded to the intermediate floor 3 or the other parts delimiting the cargo space 5.

tende Schrumpfung des Behälterbodens durch die Nach der Erfindung wird diese Aufgabe dadurchof the liquid gas container (7) at normal temperature to give the method of the above-described Catrung through the ring-shaped, rigid substructure (11), which leads to the fact that relative movements based on shrinkage in the direction of its plane are pressed so far together that the operating temperature is compressed during cooling of the liquid between the liquid gas container and the support and carrying cone gas container (7) are practically no longer possible at operating temperature,
tend shrinkage of the container bottom by the According to the invention, this object is achieved
