Abstract
Abstract The invention relates to a new construction for a confined space such as a building for containing dangerous explosive material, for instance a building adapted to be used in connection with the production, handling and/or storing of explosives, ammunition or other explosive goods. The walls of the building comprises an internal and an external cylindrical shell construction with upwardly open cylindrical shells, the spacing therebetween being filled with sand. The shells are attached to a circular floor- or bottom plate. The roof construction of the building comprises a web structure anchored to the internal cylindrical shell and on top of which web structure is positioned a cover which preferably should be of resolved or defibrated material. On top of the cover is positioned a layer of sand, and finally a roof covering on top of the sand layer.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
208 words
A building structure for the storage or production of explosive materials, said building structure comprising: a floor plate; an inner cylindrical metal shell rigidly attached at the bottom thereof to said floor plate; an outer cylindrical metal shell rigidly attached at the bottom thereof to said floor plate, said outer shell being arranged coaxially around said inner shell with a cylindrical space between said inner and outer shells, said cylindrical space being filled with sand; a rigid web roof supporting structure fixedly attached to said inner shell, the attachment of said web structure to said inner shell being of sufficient strength to prevent separation of said web structure from said inner shell upon the occurrence of an explosion of an anticipated strength of explosive material within said inner shell, said web structure having vertical extending openings therein for escape therethrough of explosive gas resulting from such explosion; a cover positioned directly on top of said web structure; a layer of sand positioned on top of said cover; an outer roof covering positioned directly on top of said layer of sand; and said cover and outer roof covering being formed of materials incapable of being broken into projectiles upon being lifted upwardly by an explosion within said inner shell.
Claim 2
Dependent Claim
208 words
A building structure for the storage or production of explosive materials, said building structure comprising: a floor plate; an inner cylindrical metal shell rigidly attached at the bottom thereof to said floor plate; an outer cylindrical metal shell rigidly attached at the bottom thereof to said floor plate, said outer shell being arranged coaxially around said inner shell with a cylindrical space between said inner and outer shells, said cylindrical space being filled with sand; a rigid web roof supporting structure fixedly attached to said inner shell, the attachment of said web structure to said inner shell being of sufficient strength to prevent separation of said web structure from said inner shell upon the occurrence of an explosion of an anticipated strength of explosive material within said inner shell, said web structure having vertical extending openings therein for escape therethrough of explosive gas resulting from such explosion; a cover positioned directly on top of said web structure; a layer of sand positioned on top of said cover; an outer roof covering positioned directly on top of said layer of sand; and said cover and outer roof covering being formed of materials incapable of being broken into projectiles upon being lifted upwardly by an explosion within said inner shell.
Claim 3
Dependent Claim
17 words
A building structure as claimed in claim 1, wherein said cover is formed of a defibrated material.
Claim 4
Dependent Claim
18 words
A building structure as claimed in claim 1, wherein said inner shell is thicker than said outer shell.
Claim 5
Dependent Claim
22 words
A building structure as claimed in claim 3, wherein said inner shell comprises at least two concentric adjacent metal shell plate structures.
Claim 6
Dependent Claim
26 words
A building structure as claimed in claim 1, wherein the thickness of said layer of sand is greater than the radial thickness of said cylindrical space.
Claim 7
Dependent Claim
25 words
A building structure as claimed in claim 1, further comprising an insulating layer provided between said outer shell and said sand within said cylindrical space.
Claim 8
Dependent Claim
24 words
A building structure as claimed in claim 1, further comprising an insulating layer provided between said outer roof covering and said layer of sand.
Claim 9
Dependent Claim
31 words
A building structure as claimed in claim 1, further comprising a sand support bed positioned immediately below said floor plate, and an insulation layer positioned outwardly of said sand support bed.
Claim 10
Dependent Claim
28 words
A building structure as claimed in claim 1, wherein said outer roof covering extends outwardly of and overlaps said outer shell and is attachEd to said outer shell.
Claim 11
Dependent Claim
25 words
A building structure as claimed in claim 1, further comprising a sheet of moisture resistant material positioned between said cover and said layer of sand.
Claim 12
Dependent Claim
30 words
A building structure as claimed in claim 1, wherein said web structure comprises a plurality of horizontally extending metal elements, each attached at opposite ends thereof to said inner shell.
Claim 13
Dependent Claim
17 words
A building structure as claimed in claim 11, wherein said metal elements extend parallel to each other.
Claim 14
Dependent Claim
71 words
A building structure as claimed in claim 11, wherein said metal elements are mounted in a pattern to each extend eccentrically to the center of said inner shell, each of said metal elements being fixedly attached at the outer ends thereof to said inner shell and at the inner ends thereof to each other, whereby outward deformation of said inner shell will result in bending and twisting of said web structure.
Claim 15
Dependent Claim
96 words
A building structure as claimed in claim 1, wherein the upper surface of layer of sand is in the form of a cone centered about the longitudinal axis of said inner shell, said upper surface of said layer of sand being flush with the upper edge of said inner shell, and the upper surface of said sand in said cylindrical space slopes upwardly and inwardly at the same angle as said layer of sand, said outer roof covering having a continuous and equal slope from said longitudinal axis of said inner shell to said outer shell.
Claim 16
Dependent Claim
36 words
A building structure as claimed in claim 1, further comprising a tunnel-shaped opening extending through said inner shell and said outer shell, and a curved door positioned within said inner shell for selectively closing said opening.
