Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
146 words
A method for assembling a roof structure comprising the steps of: placing a platform having a restraining means on a solid foundation; covering the platform with an impervious material formable into an arcuate configuration; placing a plurality of substantially identical blocks on said impervious material on end in side by side juxtapositioned arrangement; placing a plurality of wedges on top of and at each of the junctions of said blocks; forming said impervious material by applying fluid under pressure underneath it to raise said material causing said blocks to separate and said wedges to slip between said blocks, said impervious material forming into an arcuate configuration causing said blocks and said wedges to form an arcuate configuration; and exhausting fluid under pressure from underneath said material to atmosphere wherein said blocks and wedges are in compression exerting lateral thrust on the restraining means of said platform.
Claim 2
Independent Claim
146 words
A method for assembling a roof structure comprising the steps of: placing a platform having a restraining means on a solid foundation; covering the platform with an impervious material formable into an arcuate configuration; placing a plurality of substantially identical blocks on said impervious material on end in side by side juxtapositioned arrangement; placing a plurality of wedges on top of and at each of the junctions of said blocks; forming said impervious material by applying fluid under pressure underneath it to raise said material causing said blocks to separate and said wedges to slip between said blocks, said impervious material forming into an arcuate configuration causing said blocks and said wedges to form an arcuate configuration; and exhausting fluid under pressure from underneath said material to atmosphere wherein said blocks and wedges are in compression exerting lateral thrust on the restraining means of said platform.
Claim 3
Dependent Claim
29 words
The method set forth in claim 1 in further combination with the step of removing said impervious material from said roof structure upon exhaustion of said fluid under pressure.
Claim 4
Dependent Claim
47 words
The method set forth in claim 1 wherein said impervious material comprises a bladder and said bladder is inflated by fluid under pressure to raise said blocks and wedges until they form an arcuate configuration in compression exerting lateral thrust on said restraining means of said platform.
Claim 5
Dependent Claim
21 words
The method set forth in claim 1 in further combination with the step of guiding each wedge between juxtapositioned building blocks.
Claim 6
Dependent Claim
21 words
The method set forth in claim 1 in further combination with the step of biasing each wedge between juxtapositioned building blocks.
Claim 7
Dependent Claim
27 words
The method set forth in claim 1 wherein a plurality of substantially identical cylindrical building blocks are placed in side by side arrangement on said impervious material.
Claim 8
Dependent Claim
29 words
The method set forth in claim 1 wherein a weight of variable mass is placed over the center of the identical blocks for retarding expansion in a predetermined manner.
Claim 9
Dependent Claim
24 words
The method set forth in claim 1 including: attaching said blocks to said impervious material before applying fluid under pressure underneath the impervious material.
Claim 10
Dependent Claim
34 words
The method set forth in claim 8 wherein the blocks attached to the impervious material project downwardly from the bottom side of the impervious material and said wedges are located below said impervious material.
Claim 11
Independent Claim
147 words
A method of making a convex curved structure comprising: providing a surface to be covered by the structure, placing on said surface a fluid impervious means formable into a curved configuration, associating a plurality of block means with said impervious means in side-by-side juxtapoSitioned arrangement, locating a plurality of wedge means adjacent upper portions of and at the junctions of adjacent block means, forming said structure by subjecting said fluid impervious means to fluid under pressure to raise said fluid impervious means, the block means and the wedge means from the surface into a convex curved configuration causing the block means to separate from each other and said wedge means to move between said block means, and exhausting the fluid under pressure from said fluid impervious means wherein said block means and wedge means cooperate with each other to maintain the convex curved configuration of the structure.
Claim 12
Independent Claim
147 words
A method of making a convex curved structure comprising: providing a surface to be covered by the structure, placing on said surface a fluid impervious means formable into a curved configuration, associating a plurality of block means with said impervious means in side-by-side juxtapoSitioned arrangement, locating a plurality of wedge means adjacent upper portions of and at the junctions of adjacent block means, forming said structure by subjecting said fluid impervious means to fluid under pressure to raise said fluid impervious means, the block means and the wedge means from the surface into a convex curved configuration causing the block means to separate from each other and said wedge means to move between said block means, and exhausting the fluid under pressure from said fluid impervious means wherein said block means and wedge means cooperate with each other to maintain the convex curved configuration of the structure.
Claim 13
Dependent Claim
23 words
The method defined in claim 10 including: placing weight means on the block means before the forming of structure to a curved configuration.
Claim 14
Dependent Claim
27 words
The method of claim 10 including: removing said fluid impervious means from said structure after the fluid under pressure has been exhausted from the fluid impervious means.
Claim 15
Dependent Claim
25 words
The method set forth in claim 10 including: attaching said block means to said impervious means before applying fluid under pressure underneath the impervious means.
Claim 16
Dependent Claim
36 words
The combination set forth in claim 13 wherein: the block means attached to the impervious means project downwardly from the bottom side of the impervious means and said wedge means are located below said impervious means.
Claim 17
Dependent Claim
24 words
The method defined in claim 10 including: biasing each wedge means to a position between adjacent block means during the formation of said structure.
Claim 18
Dependent Claim
34 words
The method of claim 10 including: providing apertures in said fluid impervious means, and projecting a portion of said block means through said apertures to support said block means on the fluid impervious means.
