Patent ID: 8337736

Claim:
A method for automatically building conglomerate structures, comprising: modelling in a computer-aided way a building or other masonry construction structure by a CAD software by a surface- or a solid-modelling CAD software, thus obtaining a model of said structure, said model stored in a file of a computer memory; modelling by said CAD software a containing shell about said building structure, thus obtaining a model of said containing shell, said model stored in a file of said computer memory; extracting from said model of said structure and from said model of said containing shell a plurality of planar cross-sections on a plurality of horizontal section planes, said section planes evenly spaced at a prefixed vertical pitch, said planar cross-sections comprising filled areas and blank areas respectively corresponding to filled portions and blank portions of said structure and of said containing shell in said section planes, said planar cross-sections being sorted from below towards an area above; prearranging a fixed frame on which a moving unit slides, said moving unit suitable for alternately depositing a granular material layer and spraying a binding material in a liquid form on said granular material layer; depositing a first uniform horizontal layer of said granular material by said moving unit, said first layer having a thickness related to said prefixed vertical pitch; spraying a predetermined amount of said binding material by said moving unit on said first layer of said granular material, said spraying being limited to said filled areas of a first planar cross-section; vertically raising said moving unit with respect to said fixed frame; depositing a second uniform horizontal layer of granular material on said first layer and spraying a predetermined amount of binding material on said second layer, said spraying being limited to said filled areas of a second cross-section; repeating said step of depositing said granular material and repeating said step of spraying a predetermined amount of binding material at said filled areas of each respective cross-section until a last layer is complete, thus obtaining at least one monolithic body corresponding to said building or other masonry construction structure, and at least one monolithic body corresponding to said containing shell, wherein inner blank spaces are filled with loose granular material; and demolishing said containing shell and removing said loose granular material obtaining said building or other masonry construction structure.
