Patent

CA 2674905

A flange joint for structural members is provided, wherein by avoiding stress concentration at a welded portion, the cross-sectional size can be determined based on the base material strength, and a structure can be reduced in weight and size. In a flange joint (20) for structural members, structural members are connected to each other in a state where an end face (21a), for example, of an H-shaped steel beam (21) is connected to a structural-member-connecting face (22a) of an end plate (22) by welding and a non-connection face (22b) of the end plate (22) is coupled to another structural member. The structural-member-connecting face (22a) of the end plate (22), to which the end face (21a) of the H-shaped steel beam (21) is connected, is provided with recessed grooves (23) along the shape of the welded portion of the end face (21a).

L'invention concerne un joint à bride destiné à un élément de charpente où la réduction du poids et des dimensions d'une charpente peut être réalisée en évitant les concentrations de contraintes sur une partie de soudure, la taille de sa section droite pouvant être déterminée sur la base de la résistance du matériau de base. Dans le joint à bride (20) pour élément de charpente, la surface terminale (21a) d'un profilé (21) en H en acier ou similaire est soudée au côté d'une plaque (22) d'extrémité formant surface (22a) de jointure avec un élément de charpente, la surface (22b) de la plaque (22) d'extrémité ne participant pas à la jointure étant alignée avec un élément de charpente à joindre et, dans ces conditions, des éléments de charpente sont joints l'un à l'autre. Des parties rainurées (23) en retrait sont ménagées sur le côté de la plaque (22) d'extrémité formant surface (22a) de jointure avec l'élément de charpente, auquel est jointe la surface terminale (21a) du profilé (21) en H en acier, le long de la forme de la partie de soudure de la surface terminale (21a).
