PRINTING HEAD FOR PRINTING OF THREE-DIMENSIONAL CONCRETE STRUCTURES AND METHOD FOR SUCH PRINTING Russian patent published in 2022 - IPC B28B1/00 B28B3/20 B28B3/22 B33Y30/00 E04B1/35 E04B2/84 E04G21/04 

FIELD: printing.

SUBSTANCE: group of inventions relates to printing head (1) for printing of three-dimensional concrete structures, as well as to a method, in which such a printing head is used for stacking of layers of concrete material one above the other. Printing head (1), according to the invention, is made with the possibility of movement in space and stacking, one above the other, of separate layers (20a) of concrete material, which forms a manufactured structure. Moreover, printing head (1) contains supplying device (2), transporting device (3), molding section (4), releasing section (5) directed opposite to supplying direction (A) of printing head (1), and release-preventing section (6). Supplying device (2) is made with the possibility of provision of concrete material. Transporting device (3) is made with the possibility of reception of concrete material from supplying device (2) and transportation of concrete material. Molding section (4) is made with the possibility of being filled with concrete material under pressure and setting of at least side dimensions of stacked layer (20a). Releasing section (5) is directed opposite to supplying direction (A) of printing head (1). Release-preventing section (6) is made with the possibility of prevention of release of concrete material in supplying direction (A) of printing head (1).

EFFECT: increase in the efficiency of printing of three-dimensional concrete structures, and prevention of accumulation and soaking of concrete.
