Abstract
Abstract A method of erecting a permanent silo structure including the steps of assembling a plurality of transversely precurved, coiled wall members around the perimeter of a base, with the free ends of the wall members extending vertically upwardly and terminating in a common horizontal plane; inserting filler members between each of the wall members to create a sealed structure; assembling a roof to the free ends of the wall members; incrementally applying an upward force to unroll the coiled wall members to elevate the structure; and securing compressive members in vertically spaced positions around the perimeter of the wall members and filler members after each increment of upward force is applied.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
155 words
The method of constructing a permanent storage structure comprising the steps of: a. providing a fixed, permanent base; b. assembling a plurality of long, narrow wall staves around the perimeter of said base with their lateral edges in juxtaposition with one another so that they surround the base, each of said staves being coiled about a transverse axis so as to occupy a generally cylindrical space; c. partially uncoiling said staves so that a free end of each of said staves extends vertically upwardly and terminates in a common horizontal plane with the free ends of the other staves; d. assembling a roof structure on the free ends of said staves to secure said free ends together; e. applying an upward force to the coiled staves to simultaneously unroll said staves thereby elevating the free ends of said staves and said roof; and f. securing the lower ends of said staves permanently to said base.
Claim 2
Independent Claim
155 words
The method of constructing a permanent storage structure comprising the steps of: a. providing a fixed, permanent base; b. assembling a plurality of long, narrow wall staves around the perimeter of said base with their lateral edges in juxtaposition with one another so that they surround the base, each of said staves being coiled about a transverse axis so as to occupy a generally cylindrical space; c. partially uncoiling said staves so that a free end of each of said staves extends vertically upwardly and terminates in a common horizontal plane with the free ends of the other staves; d. assembling a roof structure on the free ends of said staves to secure said free ends together; e. applying an upward force to the coiled staves to simultaneously unroll said staves thereby elevating the free ends of said staves and said roof; and f. securing the lower ends of said staves permanently to said base.
Claim 3
Dependent Claim
22 words
The method of claim 1 which includes the step of transversely precurving said staves prior to their assembly around the structure base.
Claim 4
Dependent Claim
32 words
The method of claim 1 in which said upward force is incrementally applied, and including the steps of securing a compressive member around the perimeter of said staves after each force increment.
Claim 5
Dependent Claim
42 words
The method of claim 1 wherein said upward force is applied by driving the coil of at least one of said coiled staves, with the non-driven coils being coupled to the driven coil so that all of said staves are elevated simultaneously.
Claim 6
Dependent Claim
16 words
The method of claim 1 in which said upward force is applied to said roof structure.
Claim 7
Dependent Claim
31 words
The method of claim 5 including the step of erecting a tower above said base inwardly of said staves, and applying said upward force to said roof structure from said tower.
Claim 8
Dependent Claim
36 words
The method of claim 5 including maintaining said base, staves, and roof structure in a substantially sealed condition, and applying said upward force to said roof structure by introducing fluid under pressure beneath said roof structure.
Claim 9
Dependent Claim
24 words
The method of claim 1 including the step of sealing a filler member between each pair of adjacent staves as the staves are elevated.
Claim 10
Dependent Claim
31 words
The method of claim 8 in which the filler members are precoiled and assembled around the perimeter of the base between the coiled staves, and are elevated continuously with the staves.
Claim 11
Dependent Claim
36 words
The method of claim 8 in which the filler members are in short segments, the upward force is incrementally applied, and a segment is inserted between adjacent staves in conjunction with each incremental application of force.
Claim 12
Dependent Claim
30 words
The method of claim 8 in which the filler members are hollow, and a setting flowable material is injected into the filler members after they are assembled with the staves.
Claim 13
Independent Claim
235 words
The method of constructing a permanent storage structure comprising the steps of: a. providing a fixed, permanent base; b. assembling a plurality of long, narrow transversely pre-curved wall staves around the perimeter of said base with their lateral edges in juxtaposition with one another so that they surround the base, each of said staves being coiled about a transverse axis so as to occupy a generally cylindrical space; c. partially uncoiling said staves so that a free end of each stave extends vertically upwardly and terminates in a common horizontal plane with the free ends of the other staves; d. assembling a plurality of coiled fIller members around the perimeter of said base, one filler member being provided between each two adjacent staves; e. inserting the free end of each filler member between the free ends of adjacent staves; f. securing a compressive member around the perimeter of said staves and filler members; g. assembling a roof structure to the free ends of said staves; h. incrementally applying an upward force to the assembled structure to unroll the coiled staves and filler members thereby elevating the free ends of said staves, filler members and roof structure; i. securing additional compressive members around the perimeter of said staves and filler members at vertically spaced positions after each increment of upward force is applied; and j. securing the lower ends of said staves permanently to said base.
