Abstract

In a container for liquefied gas, the supporting container construction consists of steel-reinforced or pre-stressed concrete in which the reinforcement is a steel ductile in the cold state; and a vapour seal layer is provided on the inside of the container wall and has a laminated heat-insulating layer consisting of a closed cell plastic foam, e.g. foamed polyurethane. The vapour seal layer pref. consists of a synthetic resin, e.g. epoxy resin. The system is used partic. for marine tankers for transport of liquefied natural gas, since the hull can form the container.

"Aus Stahl- oder Spannbeton bestehender Behälter für"Containers made of reinforced or prestressed concrete for

Flüssiggas"Liquefied petroleum gas "

Die Erfindung betrifft einen aus Stahl- oder Spannbeton bestehenden Behälter für Flüssiggas nach Patent,..1 (Patentanmeldung P 24 2J5 381.6), der auf der Innenseite rriit einer dampfdichten Isolierschicht, z.B. aus Epoxyharz und einer darauf aufgebrachten Isolierschicht gegen Wärmedurchgang, z.B. aus geschlossenzelligem Polyurethanschaum, versehen ist.The invention relates to a container made of reinforced or prestressed concrete for liquefied gas according to patent, .. 1 (patent application P 24 2J5 381.6), which has a vapor-tight insulating layer on the inside, e.g. made of epoxy resin and an insulating layer applied to it against heat transmission, e.g. closed-cell Polyurethane foam.

Gegenstand des Hauptpatents ist ein. Flüssiggas-Behälter, bei dem vor allem der Vorteil des Baustoffs · Beton mit einer Bewehrung aus kaltzähem Stahl ausgenutzt wird, daß wegen seiner Kältefestigkeit die sonst aus Sicherheitsgründen erforderliche zweite Barriere entfallen kann, da neben der Isolierung gegen Wärmedurchgang eine Dampfsperrsohicht genügt. The main patent is a. Liquefied gas tank, in which the advantage of the building material, concrete with a reinforcement made of cold-tough steel, is used that, because of its cold resistance, the second barrier, which is otherwise required for safety reasons, can be dispensed with , as a vapor barrier layer is sufficient in addition to the insulation against the passage of heat.

Beton hat bei Berührung mit Wasser oder Wasserdampf die Eigenschaft, daß er nur scheinbar wasserdicht ist. üblicherweise wird allerdings der Durchtritt von Feuchtigkeit nicht bemerkt, weil er "sehr gering ist und die Feuchtigkeit auf der Innenseite der betreffenden Betonfläche sogleich wieder verdunstet. Wenn aber auf der Innenseite eine wasserdichte Dampfsperrechicht angeordnet ist, läßt sich oftmals feststellen, daß sich in Hohlräumen im Beton Wasser ansammelt, das durch Kondensation des durch den Beton hindurchgedrungenen Dampfes entstanden ist. Wenn nun an einzelnen Stellen die Dampfsperrschicht nicht exakt und fest am Beton anhaftet, was auch bei Anwendung größter Sorgfalt nicht immer zu vermeiden ist, dann kann sich ein direkt auf die Schicht wirkender Druck aufbauen, der zur stellenweisen Ablösung der Schicht und zur Blasenbildung Anlaß geben kann. Infolge dieser Erscheinungen 1st die an der Innenseite aufgetragene DampfSperrschicht gefährdet.When it comes into contact with water or water vapor, concrete has the property that it is only apparently watertight. Usually, however, the passage of moisture is not noticed because it is "very small and the moisture on the inside of the concrete surface in question evaporates again immediately Concrete collects water that was created by condensation of the vapor that has penetrated the concrete. If the vapor barrier layer does not adhere exactly and firmly to the concrete at individual points, which cannot always be avoided even with the greatest care, it can directly affect the build layer acting pressure which can give to make wise detachment of the layer and the formation of bubbles rise. As a result of these phenomena 1st the applied on the inside vapor barrier layer at risk.

Aufgabe der Erfindung ist es, eine Möglichkeit zu schaffen, um die Dampfsperrschicht bei einem Be- I hälter der eingangs angegebenen Art vor den Einwirkungen des Wasserdampfes zu schützen.Object of the invention is to provide a way to protect the vapor barrier layer at a loading I containers of the initially stated kind from the effects of water vapor.

Die Erfindung löst diese Aufgabe dadurch, daß in der Behälterwandung ein System von miteinander in Verbindung stehenden Hohlräumen angeordnet ist, in denen ein natürlicher oder künstlicher Zug herrscht.The invention solves this problem in that a system of each other in the container wall communicating cavities is arranged in which there is a natural or artificial train.

Die Hohlräume sind zweckmäßig aus einbetonierten Rohren aus einem Material ausgebildet, das in seiner Durchlässigkeit Beton entspricht. Die Rohre bestehen zweckmäßig aus Asbestzement· The cavities are expediently formed from pipes embedded in concrete made of a material which corresponds to concrete in terms of its permeability. The pipes are expediently made of asbestos cement

Durch die Erfindung wird erreicht, daß der durch die Betonschicht hindurch diffundierende Wasserdampf, der auch durch die Wandungen der Rohrleitungen hindurchtreten kann, an der Innenwand dieser Rohrleitungen kondensiert und von dort ablaufen oder abgezogen werden kann, wenn nicht eine natürliche Belüftung der Rohrleitungen zu erreichen ist. Zur künstlichen Belüftung kann in den Rohrleitungen ein Luftkreislauf durch Einpressen von Luft aufrechterhalten werden. . ■The invention achieves that the water vapor diffusing through the concrete layer, which can also pass through the walls of the pipelines, on the inner wall of these pipelines condenses and can run off or be withdrawn from there, if there is no natural ventilation of the pipelines can be achieved. An air circuit can be injected into the pipelines for artificial ventilation be sustained by air. . ■

Die Rohre zur Herstellung der BelUftungsleitungen werden zweckmäßig in horizontaler Richtung angeordnet, weil der Betonkörper in horizontalen Schichten betoniert wird und sich die Rohre so am besten eingliedern lassen. The pipes for making the ventilation ducts are expediently arranged in a horizontal direction, because the concrete body is concreted in horizontal layers and this is the best way to integrate the pipes.
