<p>The present invention concerns a support pillar comprising a base structure (6), one or more middle structures (7) and a top structure (3) comprising top support surface (1b) for supporting a profile (10), which is provided with a first and a second guiding plates (2a, 2b) standing upright on either side of a first imaginary straight line (X1) crossing the centroid of said top surface (1b), and wherein the interface between each of the first and second guiding plates and the second main surface (1 b) define a first and a second coupling lines (21a, 21b), respectively, each having a first and second end points, characterized in that each of the first and second coupling lines (21a, 21b) are curved, forming a concavity facing away from said first imaginary straight line (X1) and in that, the ratio, Dmax / dmin, of the length, Dmax, of the longest straight segment joining two points belonging to the first and the second coupling lines (21a, 21b) without crossing any coupling line to the length, dmin, of the shortest segment joining two points belonging to the first and the second coupling lines (21a, 21b) without crossing any coupling line is higher than the same ratio obtained with two rectilinear coupling lines (21r, 21s) sharing the same end points than the non- rectilinear coupling lines.</p> |
