A riser arrangement or plane framework for shelf systems and the like comprises upright members (1) having a C-shaped profile in cross section with a stem portion (2), two opposing side walls (3, 4) and inwardly directed flanges (5, 6). The ends of diagonal stays (15, 16) are introduced into the opening (13) between the flanges (5, 6) and secured by means of bolts (20) at junction points. In both side walls (3, 4) of the C-profile, longitudinal, external grooves (7, 8) are formed. At the bottom wall (9) of the external grooves (7, 8), a plurality of holes is provided, preferably uniformly spaced apart. Within the C-profile, the distance between the inside faces of the grooves (7, 8) is greater than the distance between the edges of the flanges (5, 6). The distance between the flanges (5, 6) is sufficient to permit the introduction of two diagonal stays (15, 16) side-by- side or interdigitated. <IMAGE> |
