摘要

Knot for configuring a grid as separating element of reinforcements in concrete structures, characterized in that it consists of a piece (1), preferably made of plastic material and obtained by mold, which adopts a cross-shaped planar configuration, comprising identical arms, crossed with each other, which determine radial blades (2), which have a u-shaped section, each of said blades (2) being provided, approximately in its middle area, with at least one pin (3) able to be inserted in the hole that, for this purpose, will be provided at the ends of the spacer elements to be joined to form the reticulated structure to which it is intended; in which said piece (1) has, inferiorly, support legs (4), whose length will be the one that will mark the distance or separation to the formwork; and in that, at the top of the piece (1) and in its central zone between the described legs (4), there is a small orifice stud (5) able to allow the insertion of a nail to fix the piece to the formwork.
