Abstract
Abstract A prestressed concrete structure for the storage of liquified gas comprises an inner and outer concrete facing maintained in spaced relationship. Insulating material is positioned between the facings and the inner facing is saturated with moisture. When the structure is filled with liquified gas, the tension due to thermal stresses is partially relieved and both facings act together to withstand the forces on the structure.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
84 words
A structure for the storage of liquified gas maintained at low temperatures comprising, a structural element forming at least part of said storage structure comprising in combination an inner and an outer concrete facing maintained in spaced-apart relationship, a rigid insulating material positioned between said inner and outer concrete facings, means for saturating said inner facing with moisture, said inner and outer facings and insulating material cooperatively arranged so that loading on the structure is resisted by both the inner and outer concrete facings.
Claim 2
Dependent Claim
84 words
A structure for the storage of liquified gas maintained at low temperatures comprising, a structural element forming at least part of said storage structure comprising in combination an inner and an outer concrete facing maintained in spaced-apart relationship, a rigid insulating material positioned between said inner and outer concrete facings, means for saturating said inner facing with moisture, said inner and outer facings and insulating material cooperatively arranged so that loading on the structure is resisted by both the inner and outer concrete facings.
Claim 3
Dependent Claim
32 words
the storage structure of claim 1 wherein said structural element forms the floor, wall and roof of the storage structure and wherein said storage structure further includes means for precompressing said structure.
Claim 4
Dependent Claim
42 words
The storage structure of claim 2 wherein said storage structure further includes a plurality of nozzles positioned on the inside of said structure for supplying moisture to the interior of said structure for saturating the inner facing of said structure with moisture.
Claim 5
Dependent Claim
39 words
The storage structure of claim 2 wherein said storage structure further includes a plurality of nozzles positioned on the inside of said structure for producing an environment of 100 percent relative humidity in the interior of said storage structure.
Claim 6
Dependent Claim
43 words
The storage structure of claim 2 wherein said insulating material includes rigid connectors coupled between said inner and outer facings forming cavities therebetween, said cavities being filled with loose insulating material completely encapsulated to form a vapor barrier surrounding the loose insulating material.
Claim 7
Dependent Claim
44 words
The storage structure of claim 2 further including means formed between the inner facing and said rigid insulation and said outer facing and said rigid insulation for providing a gas and vapor-tight barrier to prevent gas or vapor from escaping from said storage structure.
Claim 8
Dependent Claim
27 words
The storage structure of claim 6 where at least one of said barriers is a metal liner positioned between one of the facings and the insulating material.
Claim 9
Dependent Claim
17 words

Claim 10
Dependent Claim
14 words
The storage structure of claim 6 wherein vapor barrier is a continuous resinous coating.
Claim 11
Dependent Claim
53 words
The storage structure of claim 2 wherein said walls further Include hinged joints positioned at various preselected intervals along the wall and extending between the inner surface of the inner facing and the outer surface of said outer facing for relieving tensile stresses on the concrete facings in the vertical and radial directions.
Claim 12
Dependent Claim
43 words
A storage structure of claim 10 wherein said hinge joints extend circumferentially around the entire storage structure and comprise a central bearing pad extending between the inner and outer facings through the insulating material and connector means connecting said facings to said joints.
