The central part (6) forming a depression on the lateral wall (9) of the sections forming the uprights (1) of the shelving is provided with cut openings (5) having sloping seats (7), said opening being intended to receive skewed tongues (4) provided on the stirrups (3) soldered at the end of the assembly cross-bars (2). Such double skewness forces the stirrups (3) to adhere to both perpendicular faces of the uprights (1), with a force which increases as the load applied to said cross-bars increases. |
