MOBILE CONCRETE AND STEEL FIBER LAYERING PLANT Russian patent published in 2022 - IPC B28C5/40 

FIELD: building materials.

SUBSTANCE: invention relates to the building materials industry. Mobile installation for layer-by-layer laying of concrete mixture and steel fibers includes a hopper for their supply, mounted on a steel frame, made conical with converging walls forming a rectangular neck, and with a size that ensures the turn of the steel fiber in the direction of installation movement and does not interfere with the passage of coarse concrete aggregate . The steel frame is mounted on a spring chassis, and on the frame behind the hopper there is a vibrating element with an eccentric, under which there is a steel comb with a number of teeth, the distance between which is greater than the size of the coarse filler mixture, but shorter than the length of the fibers, and with the ability to perform reciprocating height adjustment for the final orientation of the fibers during laying. The hopper contains removable gates that form separate compartments for the concrete mixture, steel fiber and fiber pre-orientation compartments.

EFFECT: creating a directional orientation of the fibers when laying the concrete mix.
