<p>The assembly has longitudinal bars (2,3) and transversal bars (4,5,6,7) that are mounted on the longitudinal bars. The transversal bars include transversal coupling holes for free passage of the longitudinal bars. The holes are associated to corresponding lateral locking holes, each receiving a metal pin or slug for blocking the lateral translation of the transversal bars in an intended position on the longitudinal bars.</p> |
