Abstract
(EN)
[Problem] To provide a member that exhibits high load resistance and rigidity when connected to another member. [Solution] A member 1 has a transverse cross- section that includes a top plate 2, top ridgelines 4, vertical walls 3, bottom ridgelines 5, and floor flanges 9. The member 1 has, at at least one end thereof in an extension direction of the top ridgelines 4, a top plate flange 11 connected via a top plate ridgeline 6 and a vertical wall flange 10 connected via a vertical wall ridgeline 7. The vertical wall flange 10 and the floor flanges 9 are continuous with each other. The relation ΣR/ΣL ≤ 0.13 holds true for the member 1, where ΣR is the sum of radii of curvature of corner portions of the vertical walls at ends of the top ridgelines 4 and the bottom ridgelines 5, and ΣL is the sum of widths of the top plate 2 and the vertical walls 3 at an end of the member. The member 1 is manufactured through a first step of manufacturing an intermediate formed article 27 that is provided with at least flange ridgelines 8 by subjecting a blank 26 to press forming and then shrinkage flange forming the flange ridgelines 8, and a second step of subjecting the intermediate formed article 27 to press forming to thereby manufacture the member 1.

[Problème] Fournir un élément qui présente une résistance à la charge et une rigidité élevées lorsqu’il est relié à un autre élément. [Solution] Selon la présente invention, un élément 1 comporte une section transversale qui comprend une plaque supérieure 2, des lignes de crête supérieures 4, des parois verticales 3, des lignes de crête inférieures 5 et des brides de plancher 9. L’élément 1 comporte, au moins à une extrémité de celui-ci, dans une direction d’extension des lignes de crête supérieures 4, une bride de plaque supérieure 11 reliée par l’intermédiaire d’une ligne de crête de plaque supérieure 6 et une bride de paroi verticale 10 reliée par l’intermédiaire d’une ligne de crête de paroi verticale 7. La bride de paroi verticale 10 et les brides de plancher 9 sont continues les unes avec les autres. La relation ΣR/ΣL ≤ 0,13 est vraie pour l’élément 1, où ΣR est la somme des rayons de courbure des parties d’angle des parois verticales aux extrémités des lignes de crête supérieures 4 et des lignes de crête inférieures 5, et ΣL est la somme des largeurs de la plaque supérieure 2 et des parois verticales 3 à une extrémité de l’élément. L’élément 1 est fabriqué au moyen d’une première étape de fabrication d’un article formé intermédiaire 27 qui est pourvu d’au moins plusieurs lignes de crête 8 en soumettant une ébauche 26 à un formage à la presse, puis formation de bride par retrait formant les lignes de crête de bride 8, et une deuxième étape de soumission de l’article formé intermédiaire 27 à un formage à la presse de façon à fabriquer l’élément 1.
