Method of constructing building structures of zig-zag profile

Claim 1

Claim 3

A method of constructing a building structure of predetermined design formed of walls made of casting material, each wall having a zig-zag profile and consisting of a plurality of edgewise adjoining and interconnected planar, straight-edged polygonal cast slabs disposed at angle to one another, comprising the following steps: A. excavating two parallel trenches spaced from one another at a distance corresponding to the intended span of the completed building structure, each trench having a width and depth adapted to receive for anchoring and support, the lowermost wall portion of the building structure; B. building, over said trenches, a planar form having partitions enclosing upwardly open spaces of the shape of the slabs to be formed, said spaces adjoining one another with a clearance on each side; C. placing eyebars in each partition for each side of each space, the eyes of said eye bars being arranged in a vertical plane and in a horizontal alignment in each clearance; D. pouring a casting material in each partition, subsequent to steps (B) and (C), to obtain a coplanar cast slab assembly wherein slabs constituting one and the same wall follow each other along the length dimension of said structure and are disposed at an angle of 180* with respect to one another, slabs conStituting different walls follow each other along the span dimension of said structure wherein adjoining walls are disposed at an angle of 180* with respect to one another; E. placing rod means in each clearance to pass through each eye disposed therein; said eye bars and rod means forming hinges; F. removing said form after hardening of the casting material subsequent to step (D); G. attaching hoisting means to a plurality of predetermined lifting points on said coplanar slab assembly; H. imparting a dual folding to said coplanar slab assembly in a single operation for gradually forming said zig-zag profile of all of said walls and, simultaneously, gradually decreasing the angle between adjoining walls by lifting, subsequent to step (G), said cast assembly by said hoisting means to a predetermined height, whereby all the angles of inclination between any two adjoining slabs in any wall decrease in unison and have all indentical magnitudes at any moment of the folding operation, whereby each panel maintains unchanged its planar configuration at all times; I. dropping, in the course of said lifting operation, said lowermost wall portions into said trenches, whereby said predetermined height is reached; and J. fixing, subsequent to step (H), all the hinges between all the cast slabs to obtain a permanently rigid building structure.

Claim 4

A method of constructing a building structure of predetermined design formed of walls made of casting material, each wall having a zig-zag profile and consisting of a plurality of edgewise adjoining and interconnected planar, straight-edged polygonal cast slabs disposed at angle to one another, comprising the following steps: A. excavating two parallel trenches spaced from one another at a distance corresponding to the intended span of the completed building structure, each trench having a width and depth adapted to receive for anchoring and support, the lowermost wall portion of the building structure; B. building, over said trenches, a planar form having partitions enclosing upwardly open spaces of the shape of the slabs to be formed, said spaces adjoining one another with a clearance on each side; C. placing eyebars in each partition for each side of each space, the eyes of said eye bars being arranged in a vertical plane and in a horizontal alignment in each clearance; D. pouring a casting material in each partition, subsequent to steps (B) and (C), to obtain a coplanar cast slab assembly wherein slabs constituting one and the same wall follow each other along the length dimension of said structure and are disposed at an angle of 180* with respect to one another, slabs conStituting different walls follow each other along the span dimension of said structure wherein adjoining walls are disposed at an angle of 180* with respect to one another; E. placing rod means in each clearance to pass through each eye disposed therein; said eye bars and rod means forming hinges; F. removing said form after hardening of the casting material subsequent to step (D); G. attaching hoisting means to a plurality of predetermined lifting points on said coplanar slab assembly; H. imparting a dual folding to said coplanar slab assembly in a single operation for gradually forming said zig-zag profile of all of said walls and, simultaneously, gradually decreasing the angle between adjoining walls by lifting, subsequent to step (G), said cast assembly by said hoisting means to a predetermined height, whereby all the angles of inclination between any two adjoining slabs in any wall decrease in unison and have all indentical magnitudes at any moment of the folding operation, whereby each panel maintains unchanged its planar configuration at all times; I. dropping, in the course of said lifting operation, said lowermost wall portions into said trenches, whereby said predetermined height is reached; and J. fixing, subsequent to step (H), all the hinges between all the cast slabs to obtain a permanently rigid building structure.
