Abstract
A panel has a profile with width L1 comprising a first longitudinal edge comprising in succession a first longitudinal rib comprising a top center part having a height H4 and width L4 and two lateral wings that extend from the top center part on either side and downward, then a first flange having a width L3 oriented in a plane P, the two lateral wings forming an angle α with the plane P, at least one projecting part in the extension of the first flange. An upper plateau having a height H7 and width L7 and two lateral webs extending from the upper plateau on either side and downward, forming an angle β with the plane P, a second longitudinal edge in the extension of one of the projecting parts comprising in succession a second flange having a width L9 oriented in the plane P and a second longitudinal rib comprising a top center part having a height H11 and width L11 and two lateral wings extending from the top center part on either side and downward forming an angle γ with the plane P. The first and second ribs have shapes that allow their respective overlapping, where L7/L4≧5, L7/L11≧5, H7/H4≧0.4, H7≧((H4×(ab−be)−L3×abe)/(ae+ab)), H7≧((H11×(cb−be)−L9×cbe)/(ce+cb)), where a=tan α, …
