The device has a metallic wire folded into an arch in a plane, where the arch comprises jambs (2a, 2b) folded for being hooked underneath a reinforcing wire (10). The jamb (2b) is extended after its folding into a branch (5) that extends perpendicular to the plane. The branch has a length that is greater than a distance (D) separating reinforcing wires (10, 11) such that the branch is elastically pressed between the wires (10, 11). An independent claim is also included for a method of fabricating a concrete floor. |
