Abstract: A spherical storage tank holding gases or liquids which is supported on a rigid concrete foundation in a region of the vertical axis of the tank. There is interposed between tank and foundation a mounting rigidly bonded to both the tank and the foundation having generally elastomeric properties. The mounting consists essentially of a plurality of slabs covering the whole upper area of the foundation, in a spaced array leaving only narrow gaps between the individual slabs. The slabs are thin in relation to their size, and the gaps between the individual slabs are filled with a soft-plastic sealant. Moreover, the foundation consists of an upper part and a lower part, between said upper and said lower part being interposed adjustable resilient pads to allow an adjustment of the upper part in relation to the lower part to correct the position of the upper part if the lower part has been displaced due to ground shock waves, underground cavations or the like.

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.
