Self-supporting three-dimension prestressed structure, method and device for its construction

A method for construction of self-supporting three-dimensional prestressed structures comprising:

• selecting a geometric center for a structure;
• positioning and affixing a central circle (5) of a device for construction of self-supporting three-dimensional prestressed structures at a geometric center of the structure;
• configuring telescopic arms (4) of the device to conform to an intended size and shape of the structure;
• inserting one end of a vertical member (1) through a guiding block (6) on a respective telescopic arm (4) and into a prepared socket in a foundation of the structure;
• moving incrementally upward each telescopic arm (4) along its respective flexible vertical member (1), either in sequence or simultaneously, thus stressing the flexible vertical member (1);
• following each incremental upward step of all telescopic arms (4), fixing an achieved elevation by attaching horizontal flexible members (2) around the flexible vertical members (1) to form a contour;
• after the structure has been completed, removing the device (3),
• wherein the telescopic arms remain hinged to the device at a base area of the structure,
• making openings of shapes in the structure by making frames with required dimensions and shape, affixing the frames at required positions, affixing bordering sections of the structure to the frames, and cutting away excess parts of the structure enclosed in the frames, and
• sheathing the structure in reinforcing mesh and plastering over and finishing in building materials comprising at least one of cement, clay, and adhesive mix.
