The invention relates to a container for the storage of low-temperature liquids, especially liquefied gases, consisting of an outer container made of reinforced or prestressed concrete, equipped perhaps with a steel dome, and an open inner steel tank, intended to hold the liquid, the steel tank resting on an insulator; an annular space is provided between the two tanks, this space containing a granular insulating material and, in its lower part, a spacer element. In order to protect the steel tank from sliding during an earthquake and in order to absorb the horizontal forces unleashed during such an event, an annular hollow container made of steel is installed between the spacer and the wall of the concrete container, to which it is firmly attached. This hollow container, filled partially with a material that is liquefiable by heating, has some heating elements. The spacer is attached firmly to the hollow container and it is also firmly or tensionally connected to the steel tank. The material in the hollow container, which is preferable a bitumen, is heated during filling and emptying of the steel tank, and consequently does not prevent the deformations of the steel tank caused by the temperature changes during filling and emptying.

Storage container for low-temperature liquids

A container is disclosed for storing refrigerated liquids, in particular for liquefied gases, which comprises a steel reinforced concrete outer container and a steel inner container inserted into the outer container, where the steel inner container rests on an insulation and where an annular interspace is present between the outer circumference of the inner steel container and the inner circumference of the outer container. The interspace can be fully or in part of its thickness filled with insulating materials. In order to prevent the liquid pouring in a gush into the interspace and causing locally high loads acting on the steel reinforced concrete container upon a cracking of the steel inner container, several gush braking bodies protruding into the interspace are disposed at the inner circumference of the outer container and/or at the outer circumference of the inner steel container, which bodies extend in radial direction about one third of the width of the interspace, and which preferably reach only to about two thirds of the total height of the interspace and which according to a preferred embodiment are provided with a triangular cross-section.

Container for storing refrigerated liquids

A cooling tower, a process for producing a cooling tower, and a reinforcing element suitable for use in the process and tower are disclosed. The cooling tower, formed from a shell of reinforced concrete, is produced with a plurality of plate-like reinforcing elements adjacent to a surface of the shell. The reinforcing elements are disposed in at least one horizontal plane within the shell adjacent to and suspended from the shell surface. The reinforcing elements in a plane abut and are joined one to another, and are also joined to the shell at spaced points thereon. Each plate-like element includes a central channel communicating with trough-like ends for receiving a suitable reinforcing material which extends into recesses in the shell of the cooling tower adjacent the trough-like ends.
