US3755975A — Pre-fabricated shell structure

Claim 1

Independent Claim 275 words

A pre-fabricated shell structure utilizing modular structural units suitable for home construction, said structure comprising a foundation serving as a supporting base for the structure, a plurality of waterproof coated panels each shaped to define a self-supporting modular roof means including a non-metallic roof section and non-metallic contigous modular-wall sections one extending downwardly from each of opposite side end-portions of the non-metallic roof section, said shaped panels each being rigidly formed of press-shaped organic fibers with a waterproofing coating on at least a part of the outer surface of the pressed fibers forming each panel, for each panel each of opposite downwardly extending wall sections including securing means for securing each respective wall section to said foundation, means for fastening the contigous wall sections of each of two adjacent panels to each other, a rear wall panel securable between the opposing downwardly extending wall sections and the roof section of an end one of said panels, the rear wall panel being securable to the foundation, a front wall panel spaced from the rear wall panel and securable between opposite downwardly extending wall sections and the roof section of a panel of said plurality of panels and securable to the foundation, the front wall panel having means defining openings therein providing access into and out of the shell structure, said waterproof coating being a film coating at least the outershell surface of each panel''s roof and downwardly extending wall sections, each panel being a blank of pressed organic fiberous material scored in a transverse direction permitting folding of the blank into a tripartite panel having the two non-metallic contigous modular-wall sections and the non-metallic roof section.

Claim 2

Dependent Claim 275 words

A pre-fabricated shell structure utilizing modular structural units suitable for home construction, said structure comprising a foundation serving as a supporting base for the structure, a plurality of waterproof coated panels each shaped to define a self-supporting modular roof means including a non-metallic roof section and non-metallic contigous modular-wall sections one extending downwardly from each of opposite side end-portions of the non-metallic roof section, said shaped panels each being rigidly formed of press-shaped organic fibers with a waterproofing coating on at least a part of the outer surface of the pressed fibers forming each panel, for each panel each of opposite downwardly extending wall sections including securing means for securing each respective wall section to said foundation, means for fastening the contigous wall sections of each of two adjacent panels to each other, a rear wall panel securable between the opposing downwardly extending wall sections and the roof section of an end one of said panels, the rear wall panel being securable to the foundation, a front wall panel spaced from the rear wall panel and securable between opposite downwardly extending wall sections and the roof section of a panel of said plurality of panels and securable to the foundation, the front wall panel having means defining openings therein providing access into and out of the shell structure, said waterproof coating being a film coating at least the outershell surface of each panel''s roof and downwardly extending wall sections, each panel being a blank of pressed organic fiberous material scored in a transverse direction permitting folding of the blank into a tripartite panel having the two non-metallic contigous modular-wall sections and the non-metallic roof section.

Claim 3

Dependent Claim 44 words

A pre-fabricated shell structure as claimed in claim 1, wherein the blank is further scored in a longitudinal direction along two opposed sides of said blank to permit folding same to form side flaps adapted to extend into the interior of the shell structure.

Claim 4

Dependent Claim 38 words

A pre-fabricated shell structure as claimed in claim 1, and the securing means comprising an end flap one on each of the terminal lower ends of the wall sections, and the blank being cut from a larger section.

Claim 5

Dependent Claim 46 words

A prefabricated shell structure as claimed in claim 2, wherein said longitudinally scored material comprises scored parallel opposite edge-portions of the modular roof means permitting folding thereat to define side flaps adapted to extend into the interior of the shell when bent at said scored edge-portions.

Claim 6

Dependent Claim 46 words

A pre-fabricated shell structure as claimed in claim 2, wherein the means for fastening the contiguous sides of each of two adjacent respective panels includes resilient clip means frictionally engaging a side flap of each of two contiguous panels to hold said panels in abutting relationship.

Claim 7

Dependent Claim 26 words

A pre-fabricated shell structure as claimed in claim 5, further including insulating filler material frictionally positioned between the side flaps of the roof and wall panels.

Claim 8

Dependent Claim 57 words

A pre-fabricated shell structure as claimed in claim 2, further including an interior panel section adapted to fit between the side flaps of the respective roof and wall sections for rigidly holding said interior panel between the side flaps to thereby form a hollow elongated chamber and insulating fill material pneumatically placEd within the hollow elongated chamber.

Claim 9

Dependent Claim 86 words

A pre-fabricated shell structure as claimed in claim 7, wherein the means for rigidly holding the interior panel sections comprises a holding bracket, said bracket having a head portion for bracing the interior panel section, said bracket further having a leg portion containing protuberances projecting alternately from either side thereof, said leg portion being positioned between the side flaps of two adjacent roof and wall sections so that the protuberances will penetrate and grip the respective abutting side flaps of said adjacent roof and wall sections.

Claim 10

Dependent Claim 28 words

A pre-fabricated shell structure as claimed in claim 8, wherein the blank defines cut out portions therein to facilitate folding of the blank along the prescribed score lines.

Claim 11

Dependent Claim 39 words

A pre-fabricated shell structure as claimed in claim 9, wherein the pressed organic fiberous material is a chemically treated, fire-resistant cardboard and a fiberglass reinforced waterproof film is applied to the outer surface of the roof and wall panels.
