GRILL FOR REINFORCEMENT Russian patent published in 2013 - IPC D04B21/16 

FIELD: construction.

SUBSTANCE: grill comprises vertical and horizontal weft reinforcing high-module threads, which form cells of rectangular shape, threads of soil "cord" structure and a binding thread. The "cord" structure soil thread covers vertical weft threads and fixes horizontal weft threads, and the binding thread of soil is connected to threads of the "cord" structure soil. The total length of the grill L contains several repeats, location of horizontal weft threads in which is determined by mathematical relation.

EFFECT: improved shape stability of a grill with simultaneous reduction of relative extension along a vertical line due to reliable fixation of vertical weft threads, which twist around a structure "closed tricot" laps, ability to perceive higher loads in the specified zones of each repeat due to uneven laying of horizontal weft threads, providing for alternate specified flexibility along the entire length of a grill.
