Process for erecting folding slab construction

Claim 2

A process for erecting a building structure comprising: forming a series of four or more concrete roof slabs in coplanar relation each slab having two side edges diverging along straight lines from a common point and encircling said common point; simultaneously with said forming step foldably hinging each said roof slabs to two adjoining roof slabs along folding seams disposed along said straight lines diverging from said common point to encircle said common point with said foldably hinged slabs; attaching lift means to at least one of said slabs, said lift means being so positioned adjacent said common point that upon lifting said hinged slabs by said lift means said lifting provides folding at least one of said folding seams in a first angular direction; and further provides, simultaneously with folding of said one of said seams, folding at least three of said seams in a second angular direction opposite to said first angular direction; lifting said hinged slabs by said lifting means bracing said slabs as folded to maintain a building roof of strength, integrity and stability, and removing said lift means.

Claim 3

The process of claim 1 including the additional steps of: forming concrete wall slabs with said roof slabs and hingeably conjoining said wall slabs to said roof slabs; whereby said roof slabs when lifted permit said wall slabs to move pendulously to underlie said roof slabs in supporting relation.

Claim 4

The process of claim 1 including the additional step of: forming a floor slab underlying said roof slabs; and bracing said roof slabs as folded with respect to said floor slab.

Claim 5

The process of claim 3 and wherein said bracing step includes: forming wall slabs between said roof slabs and said floor slabs; hingeably conjoining said wall slabs to said roof slabs; raising said roof slabs to permit said wall slabs to move pendulously to underlie said roof slabs in supporting relation; and, fastening said wall slabs to said floor slabs to support said wall slabs as folded.

Claim 6

The process of claim 1 wherein said straight lines are disposed at equal angular intervals at about said point.

Claim 7

The process of claim 1 wherein said lifting step provides the folding of said seams to provide alternating ridges and valleys about said point.

Claim 8

The process of claim 1 wherein each of said slabs as formed is a polygon.

Claim 9

A process for erecting a building structure comprising: forming a concrete floor slab having side edges for receiving and bracing wall slabs thereto; forming concrete wall slabs in coplanar relation with said floor slab adjacent said floor slab; forming a series of four or more concrete roof slabs in coplanar relation overlying said floor and wall slabs with each roof slab including side edges defined along straight lines diverging from a common point; simultaneously with the formation of said roof slabs foldably hinging each roof slab to two adjoining roof slabs along folding seams disposed along straight lines diverging from said common point overlying said floor slab, said roof slabs as foldably hinged encircling said common point; simultaneously with said forming step of said roof slabs foldably hinging said wall slabs to said roof slabs; attaching lift means to at least one of said slabs; said lifting means being so positioned adjacent said common point that upon lifting said hinged slabs by said lift means said lifting provides raising said roof slabs to permit said wall slabs to move pendulously to underlie said roof slabs in supporting relation and folding at least one of said straight edge seams between said roof slabs in a first angular direction and folding simultaneously at least three of said straight edge seams in a second angular direction opposite said first angular direction; lifting said hinged slabs by said lifting means, fastening said wall slabs to the edges of said floor slabs to maintain said wall slabs and roof slabs in erected relation, and removing said lift means.

Claim 10

A process for erecting a building structure comprising: forming a concrete floor slab having side edges for receiving and bracing wall slabs thereto; forming concrete wall slabs in coplanar relation with said floor slab adjacent said floor slab; forming a series of four or more concrete roof slabs in coplanar relation overlying said floor and wall slabs with each roof slab including side edges defined along straight lines diverging from a common point; simultaneously with the formation of said roof slabs foldably hinging each roof slab to two adjoining roof slabs along folding seams disposed along straight lines diverging from said common point overlying said floor slab, said roof slabs as foldably hinged encircling said common point; simultaneously with said forming step of said roof slabs foldably hinging said wall slabs to said roof slabs; attaching lift means to at least one of said slabs; said lifting means being so positioned adjacent said common point that upon lifting said hinged slabs by said lift means said lifting provides raising said roof slabs to permit said wall slabs to move pendulously to underlie said roof slabs in supporting relation and folding at least one of said straight edge seams between said roof slabs in a first angular direction and folding simultaneously at least three of said straight edge seams in a second angular direction opposite said first angular direction; lifting said hinged slabs by said lifting means, fastening said wall slabs to the edges of said floor slabs to maintain said wall slabs and roof slabs in erected relation, and removing said lift means.
