Abstract

Panne destinée à une couverture de toit inclinée, les ailes (3,4) du profilé (1) pour panne formant avec l'ame (2) un angle différent de 90 degrés. Cet angle est déterminé par le fait que l'axe principal, pour le moment d'inertie le plus petit de la section du profilé, coincide, au moins de façon approchée, avec la direction de la charge subie par la couverture de toit, et que la panne doit absorber. L'ame (2) présente , à ses deux extrémités , une partie en retrait (5, 6) formant avec l'aile (3, 4) un angle inférieur à 90 degrés. Les extrémités des ailes (3, 4) sont pourvues d'une lèvre (7, 8) pliée vers l'intérieur. Cela augmente fortement la résistance du profilé au voilement.Failure intended for an inclined roof covering, the wings (3,4) of the profile (1) for failure forming with the core (2) an angle different from 90 degrees. This angle is determined by the fact that the main axis, for the smallest moment of inertia of the section of the profile, coincides, at least approximately, with the direction of the load undergone by the roof covering, and that the breakdown must absorb. The core (2) has, at its two ends, a recessed portion (5, 6) forming with the wing (3, 4) an angle less than 90 degrees. The ends of the wings (3, 4) are provided with a lip (7, 8) folded inwards. This greatly increases the resistance of the profile to warping.
