Abstract

A panel has a profile with width L 1 comprising a first longitudinal edge comprising in succession a first longitudinal rib comprising a top center part having a height H 4 and width L 4 and two lateral wings that extend from the top center part on either side and downward, then a first flange having a width L 3 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 H 7 and width L 7 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 L 9 oriented in the plane P and a second longitudinal rib comprising a top center part having a height H 11 and width L 11 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 L 7/ L 4 ≧5, L 7/ L 11 ≧5, H 7/ H 4 ≧0.4, H 7 ≧((H 4× (ab−be)−L 3× abe)/(ae+ab)), H 7≧ ((H 11× (cb−be)−L 9× cbe)/(ce+cb)), where a=tan α, b=tan β, c=tan γ and e=tan 20°.

First claim

9. The panel according to claim 7 wherein the heights H 7 and H 14 meet the following relationship: H 7 >H 14 .

10. The panel according to claim 1 wherein the top center part is planar.

11. The panel according to claim 1 , wherein the upper plateau is curved with a curvature radius greater than or equal to 1.4 times the width L 7 of the upper plateau.

12. The panel according to claim 4 wherein the upper plateau is concave.

13. The panel according to claim 4 wherein the upper plateau is convex.

14. The panel according to claim 1 , wherein the lateral webs of the at least one projecting part comprises a Z-shaped stiffener in the upper part of the webs.

15. The panel according to claim 1 , wherein the upper plateau comprises a longitudinal groove designed to allow the passage of cables.

16. The panel according to claim 1 , further comprising a stamped depression in a surface of the upper plateau designed to house an electrical junction box.

17. The panel according to claim 1 , wherein the angles α, β and γ are acute.
