METHOD OF MAKING REINFORCED CONCRETE ARTICLE ON 3D PRINTER Russian patent published in 2020 - IPC E04C2/06 B29C64/106 B33Y40/00 

FIELD: construction.

SUBSTANCE: invention relates to construction, namely to production of construction articles, and can be used for production of reinforced concrete articles on building 3D printer in factory conditions. Method of making a reinforced concrete article on 3D printer, through which a plastic solution of artificial stone material is layer-by-layer extruded through a nozzle of construction 3D printer, is reinforced. Vertical reinforcement is performed after extrusion of all layers of artificial stone material of article and before their hardening by simultaneous passing of rods with plastic tips through concrete article, position of vertical rods is fixed to hardening of artificial stone material, horizontal reinforcement of article is performed after extrusion of all layers of artificial stone material of article and before their hardening by simultaneous passage of rods with plastic tips through concrete article, position of horizontal rods is fixed to hardening of artificial stone material, wherein the arrangement of the vertical and horizontal rods is not crossed at one point, the length of the vertical rods with the plastic tip is equal to the height of the concrete article, length of horizontal rods with plastic tip is equal to width of concrete article, length of plastic tips is not less than value of protective layer of concrete, plastic mortar of artificial stone material is a dispersed reinforced fine-grained concrete mixture with a mark on workability P1, as rods there used is steel reinforcement.

EFFECT: technical result consists in reduction of material consumption of reinforced concrete article, increased speed of its erection and resource of building 3D printer, high crack resistance, quality and durability of the concrete article with possibility of its production on any construction 3D printers.
