<p>The reinforcement elements (1) (bars in bundles, lattice, mat, etc) comprise at least two bars of which the ends are offset. The reinforcement elements (1) are joined in a bundle wherein the length difference (a) between two elements is, on one hand, bigger than twice the minimum bearing length (c) and, on the other hand, at least equal to the sum of the two exceeding portions (b) of each bar at both its ends plus twice the minimum bearing length (c). Thus, the range required to include all the various lengths is reduced to a small number of elements (1), for intermediary lengths only the exceeding portions (b) of each bar have to be cut or bent.</p> |
