This invention relates to a self-supporting three-dimensional prestressed structure, as well as a method and a device for erecting same, to be employed in the construction of residential and nonresidential buildings.
The structure is constructed of vertical form-defining flexible rodlike members (1) stressed during the construction of the structure, as well as horizontal flexible rodlike members (2) each forming a closed curve. The horizontal members (2) are also stressed during construction and welded or rigidly affixed by other means to the vertical form-defining members (1).
Instead of horizontal circular members (2) the structure can be constructed completely or to some extent using a spiral member, also stressed during the construction of the structure that is rigidly affixed to the vertical form-defining flexible members (1).
