Abstract
A mounting for a spherical tank holding gases or liquids which is supported on a rigid concrete foundation in a region of the vertical axis of the tank, the mounting consisting essentially of a spaced array of rigid support elements of foamed or sponge structure, such as foam glass blocks within a matrix of light heat insulating filler such as a mixture on the basis of polyurethane. The upper and the lower surfaces of the array of support elements and matrix are coated with an elastic layer, which are bonded to the steel surface of the tank and to the top of the foundation. The upper elastic layer may consist of felted fine gauge aluminium wire, while the lower elastic layer may consist of felted mineral fibres.
