Abstract 1,182,578. Liquefied gas storage containers. PITTSBURGH-DES MOINES STEEL CO. 12 July, 1968 [2 Feb., 1968], No. 33297/68. Heading F4P. A cylindrical flat-bottomed inner cold liquefied gas storage tank is supported by a plurality of spaced modules 40, 70'Fig. 4 located between the tank bottom 30 Fig` 1 and the flat bottom 20 of an outer tank and rigidly connected together by planking 90, and the spaces between the modules and that between the cylindrical side walls 32, 22 of the inner and outer tanks are filled with heat insulating material e.g. expanded perlite or mineral wool. The modules 40 which are peripherally arranged beneath the inner tank wall 32 comprise radially extending wood blocks 42, 46, tangential blocks 44 therebetween and top plates 50 all nailed together, whereas modules 70 which support the tank bottom 30 comprise hollow rectangular frames filled with loose insulation 62 and to which are nailed the planks 90. The latter are also nailed to shoulders 56 on modules 40. The exterior of wall 32 is secured by anchor straps 66 which pass between the sector-like space between blocks 40, through a concrete levelling pad (58) Fig. 3, (not shown) and into a concrete foundation 16 supported by piles 14.
