A shelf support structure with upright posts of sheet metal sections and horizontal braces of sheet metal sections, connecting these with each other, provides with a simple structure an inherently stable connection between the posts and the horizontal braces. The sheet metal sections of the posts have an aperture at one longitudinal side and are symmetrical in cross-section with respect to a plane crossing this aperture. The aperture is terminated on both sides by flanges protruding outwardly at right angles from the walls adjoining it and a longitudinal ledge protruding into the post is located opposite the aperture, symmetrically to the plane crossing the aperture. The horizontal braces engage with their ends into the sheet metal sections forming the posts up to the wall lying opposite the aperture and are there equipped with an indentation in whose area they embrace the longitudinal ledge in the posts in a fork-like manner. |
