Title
(EN) IMPROVED METHOD FOR AUTOMATICALLY PRODUCING A CONGLOMERATE STRUCTURE AND APPARATUS THEREFOR
Abstract
(EN)
A method and an apparatus forautomatically making conglomerated structures (6). Themethod comprises a) modelling a building structure and acontaining shell about the structure by a computer using aCAD software thus obtaining a file; b) extracting sectionsof modelled structure and of modelled containing shell, bymeans of horizontal planes spaced apart of a predeterminedpitch, such that a plurality of section planes is generated,said planes being sorted from below towards above withrespect to the model of the structure and of the model ofthe shell; c) depositing by a moving unit (3) on a grounda bottom-to-top plurality of layers of granular material(22) alternate to a binding material liquid sprayed on thelayers at filled areas corresponding to filled portions ofthe of the structure and of the containing shell, accordingto a predetermined path; d) vertically raising the movingunit (3) according to a pitch between a deposited layerand the following layer; e) repeating the step of depositinggranulating material and repeating the step of spraying thebinding material on a granulated material at filled areas of the structure and of the shell as many times as the planar cross sectionsinto which said structure and the containing shell have been divided, each of said times for a different and consecutive sectionplane until the last layer (17) is complete; f) demolishing the containing shell (5) and removing unbound granular material (7)accumulated in the shell (5), thus releasing a conglomerate structure (6) that reproduces accurately said modelled structure. Theapparatus comprises a horizontal frame (1), a bridge (2) sliding on guide on the horizontal frame (1), a moving unit (3) sliding alongthe bridge (2) or integral to the bridge (29) and have a spraying head (20). The horizontal frame (1) is moved along uprights (4)by a step actuator. The apparatus comprises a plurality of "skirls" (10) that surround the containing shell (5) and are integral to thehorizontal frame (1). Such skirts scrape the outer surface of the containing shell (5) collecting the granular material (21) depositedout of the shell (5). Such skirts (10) can comprise an brush-like edge (20) suitable for externally sweeping the containing shell (5).
