Die Isolation von großen Gefäßen für die Tiefsttemperaturteehnik ist oft mit beträchtlichen Schwierigkeiten verknüpft. Ein besonders zweckmäßiges Verfahren sum Anbringen einer solchen Isolierung oder zum Schaffen einer Wandstruktur mit niedriger Wärmeleitfähigkeit ist die Technik einer schraubenförmigen Wicklung, bei der ein bandförmiger Isolierkörper in einer Schraubenbahn gewickelt wird, so daß er eine Vielzahl von Windungen bildet, und die benachbarten Windungen miteinander verbunden werden, so daß eine einheitliche Struktur entsteht. Es sind bereits Verfahren bekannt, um solche Strukturen aus einem vorgeformten Schaumstoffelement herzustellen« Eine besonders bequeme Herstellungsart für eine solche Struktur verwendet einen langen Streifen oder Balken aus einem Schaumkunststoff als Isolationsmaterial, der als eine Dimension die gewünschte Dicke der Isolation hato Wenn das Gefäß auf die Betriebstemperatur abgekühlt wird, tritt jedoch oft eine willkürliche Rißbildung in der Isolation nächst der Oberfläche des abgekühltenThe isolation of large vessels for cryogenic technology is often associated with considerable difficulties. A particularly useful method of adding one Insulation or to create a wall structure with low thermal conductivity is the technique of a helical one Winding in which a strip-shaped insulating body is wound in a helical path so that it has a plurality of turns forms, and the adjacent turns are connected to each other, so that a unitary structure is formed. Processes are already known for producing such structures from a preformed foam element. One in particular convenient way of making such a structure uses a long strip or beam from a foam plastic as an insulation material, which as one dimension has the desired thickness of the insulation o When the vessel has reached the operating temperature is cooled, however, random cracking of the insulation next to the surface of the cooled one often occurs

Eine derartige willkürliche Rißbildung kann die Wirksamkeit der Isolation beeinträchtigen und in manchen Fällen zu einer unerwünschten Schwächung; der Isolationsschicht führen.The vessel. Such random cracking can affect the effectiveness of the insulation, and in some cases to an undesirable weakening; the insulation layer lead.

Die Erfindung will einon verbesserten bandförmigen leolationskörper zur Isolierung von Kältegefäßen schaffen, der eine verminderte Rißbildung und eine geringere Tendenz der Risse, durch d-ie Isolierung weiterzulaufen, zeigt unä der sich einfach aus verfügbaren Materialien herstellen läßt.The invention aims at an improved band-shaped leolation body create for the insulation of cold vessels, the one reduced cracking and a lower tendency for cracks, Continuing to walk through the insulation shows itself to be easy can be made from available materials.

Die Erfindung sieht einen bandförmigen Isolationskörper der eingangs beschriebenen Art vor» Ler Isolationskörper ist gekennzeichnet durch mehrere innen gelegene Teile» die an der Innenfläche des Verblendungsolementes angefügt Bind und sich im wesentlichen über die gesamte Breite de3 Isolationskörpero erstrecken und von denen jeder eine Lange hat, die mit der Länge des Isolationskörpers im Einklang steht, wobei diese inneren Teile an der Innenfläche des Verblendungskörpers angefügt sind, und an wenigstens einem anderen inneren Teil anliegen.The invention provides a strip-shaped insulation body of the type described at the outset. The insulation body is characterized through several internal parts »which are attached to the inner surface of the facing element and are located in the Extend substantially over the entire width of the insulation body and each of which has a length which is consistent with the length of the insulating body, these inner ones Parts are attached to the inner surface of the facing body, and bear against at least one other inner part.

11 hat eine Außenfläche 12 und eine Innenfläche 13* Die Breite des Verblendungselementes 11 entspricht der Höhe des Isolationskörperß 10. Das Verbindungselement erstreckt sich über die gesamte Höhe des Isolationskörpers, wie in 3?ig.1 dargestellt.11 has an outer surface 12 and an inner surface 13 * the width of the facing element 11 corresponds to the height of the insulating body 10. The connecting element extends over the entire height of the insulation body, as shown in FIG. 3? Ig.1.

Auf der Außenfläche 12 des Verblendungselementes 11 ist ein Laminat 15 angebracht, das im wesentlichen die Form eines WJ" hat; d.h. sein einer Rand ist um 180 nach außen umgeschlagen, so daß ein !Flansch 17 gebildet ist. Das Laminat 15 setzt sich aus einer ersten, äußeren Lage 18, die zweckmäßig aus Metall, etwa Aluminium ist,^und einer zweiten Lage 19 zusammen, die vorzugsweise ein heißsiegelbarer Klebstoff ist. Dies kann z.B. ein Copolymerisat aus etwa 80$ Äthylen und 20$ Acrylsäure sein. Es können auch andere bekannte Klebstoffe, beispielsweise Epoxydkunstharze u.dgl. nutzbringend verwendet werden. An der Innenfläche 13 des Verblendungselementes 11 sind mehrere innere Isolierteile 21, 22, 23 und 24 aufeinanderliegend angefügt. Die Teile 21, 22, 23 und 24 bedecken zusammen die Innenfläche 13 des Verbindungselementes 11. Auf der Innenfläche ist zwischen dem Verblendungselement 11 und den inneren Seilen 21, 22, 23 und 24 ein Mull 26 zur Verstärkung angebracht, der über die Teile 21 und 24 umgeschlagen ist. Vorzugsweise ist der Mull 26 für die meisten Zwecke ein offenes Glasfasergewebe . Auf der von dem Mull 26 abliegenden Seite ist auf den Teilen 21, 229 23» 24 zweckmäßigerweise ein zweiter Mull 27 angebracht. Die aneinandergrenzenden Flächen der Teile 21 und 22 sind nicht verbunden, sondern können sich ungehindert voneinander entfernen, wenn die Temperatur der inneren Teile an den vom Laminat 15 abgelegenen Stellen herabgesetzt wird. Der zweite Mull od.er das Versteifungsgewebe 27 ist an den inneren Teilen 21, 22, 23 und 24 an einer Stelle parallel zu und abgelegen von dem Mull 26 angebracht. Die Verstärkung 27 vermindert die Tendenz zur Rißbildung, wenn die Temperatur der dieOn the outer surface 12 of the facing member 11, a laminate 15 is attached, which has substantially the shape of a W J ";!. Be that an edge is folded through 180 to the outside, so that a flange 17 is formed, the laminate 15 sets off a first, outer layer 18, which is expediently made of metal, for example aluminum, and a second layer 19, which is preferably a heat-sealable adhesive. This can be, for example, a copolymer of about 80 $ ethylene and 20 $ acrylic acid other known adhesives, for example epoxy synthetic resins, etc. can be used beneficially. Several inner insulating parts 21, 22, 23 and 24 are attached one on top of the other to the inner surface 13 of the facing element 11. The parts 21, 22, 23 and 24 together cover the inner surface 13 of the Connecting element 11. On the inner surface between the facing element 11 and the inner ropes 21, 22, 23 and 24, a gauze 26 for reinforcement is attached, which over the parts 21 and 24 is turned over. Preferably, the gauze 26 is an open fiberglass fabric for most purposes. On the side remote from the gauze 26, a second gauze 27 is expediently attached to the parts 21, 22, 9, 23 »24. The adjoining surfaces of the parts 21 and 22 are not connected, but can move away from one another unimpeded when the temperature of the inner parts is lowered at the locations remote from the laminate 15. The second gauze or the stiffening fabric 27 is attached to the inner parts 21, 22, 23 and 24 at a location parallel to and remote from the gauze 26. The reinforcement 27 reduces the tendency to crack when the temperature of the

In dem Laminat 15 sind mehrere querlaufende Riefen 29 geformt. Die Riefen 29 erstrecken sich bis zum J-förmigen Rand. Auf der Außenfläche des Laminates 15 sind entfernt von dem J-förmigen Umschlag mehrere fortlaufende Wülste 31 eines heißklebenden Klebstoffes angebracht.Reinforcement 27 load-bearing area is reduced. Appropriately, the gauze 27 is slotted at the points that the interfaces correspond between the inner parts. A plurality of transverse grooves 29 are formed in the laminate 15. The grooves 29 extend to the J-shaped edge. On the outer surface of the laminate 15 are removed from the J-shaped envelope a plurality of continuous beads 31 of a hot-melt adhesive appropriate.

Fig.2 veranschaulicht schematisch eine Struktur, die unter Verwendung der Elemente gemäß Fig.1 geschaffen ist. Die Struktur ist insgesamt mit 35 bezeichnet. Sie weist ein Gefäß 36» etwa ein Kältegefäß, auf, das von einem im wesentlichen zylindrischen Isolationskörper 37 umgeben ist. Der zylindrische Isolationskörper 37 ist aus mehreren Windungen eines Isolationsmaterials 39 hergestellt, das einen Aufbau gemäß Fig.1 hat. Jede Windung hat einen flansch 41» der dem Flansch 17 entspricht. Dieser Flansch ist nach unten gebogen5 gegen die äußere Lage der nächstunteren Windung platt gedrückt und abgedichtet, so daß eine praktisch flüssigkeitsdichte Außenfläche entsteht.FIG. 2 schematically illustrates a structure created using the elements according to FIG. The structure is denoted by 35 as a whole. It has a vessel 36, for example a cold vessel, which is surrounded by an essentially cylindrical insulating body 37. The cylindrical insulation body 37 is made from several turns of an insulation material 39, which has a structure according to FIG. Each turn has a flange 41 »which corresponds to the flange 17. This flange is bent down 5 pressed flat against the outer layer of the next lower turn and sealed, so that a practically liquid-tight outer surface is created.

Wenn man eine Isolation gemäß der Erfindung herstellt, erstrecken sich die Riefen, etwa die Riefen 29 in Fig.1, teilweise über das Laminat und sorgen für eine gesteuerte Ausbeulung des metallischen Laminates, wenn der Streifen auf ,eine Außenfläche, etwa eine sphärische Fläche, gewickelt wird. Die gesteuerte Ausbeulung infolge der Riefen, liefert eine verhältnismäßig seichte Vertiefung, die in regelmäßigen Abständen auftritt. Vorzugsweise ist die Menge des heißklebenden Klebstoffes 31, etwa ein Streifen von Bitumen, eines Äthylen-Acrylsäure-Oopolymerisates oder eines Äthylen-Vinylacetat-Copolymerisates, groß genug, daß beim Heißverschweißen des Außenelementes mit dem benachbarten Streifen, wie in Fig.2 angedeutet, die flachen Vertiefungen, die den Riefen entsprechen, ausgefüllt werden und man eine flüssigkeitsfeste Außenfläche erhält.When an insulation is produced according to the invention, the grooves, such as the grooves 29 in Figure 1, extend partially over the laminate and ensure a controlled bulging of the metallic laminate when the strip is on an outer surface, roughly a spherical surface, is wrapped. The controlled bulging as a result of the grooves provides a relatively shallow depression that occurs at regular intervals. Preferably is the amount of hot melt adhesive 31, for example a strip of bitumen, an ethylene-acrylic acid copolymer or an ethylene-vinyl acetate copolymer, large enough that when the outer element is hot-welded with the adjacent strip, as indicated in Fig.2, the Shallow depressions, which correspond to the grooves, are filled and a liquid-resistant outer surface is obtained.
