Abstract

La présente invention vise à produire un empilement de tôles d'acier qui permet à des matériaux d'être réduits sans qu'une partie de raccord femelle et une partie de raccord mâle ne se séparent. À cet effet, la présente invention porte sur un empilement de tôles d'acier, lequel empilement comporte des parties de bride des deux côtés de la partie de corps principal, lesquelles font saillie à partir du côté avant vers le côté arrière, la partie de raccord mâle étant formée sur une extrémité libre de l'une des parties de bride qui constitue la première partie de bride, et la partie de raccord femelle étant formée sur une extrémité libre d'une autre des parties de bride qui constitue la seconde partie de bride. La partie de raccord mâle est repliée vers le côté arrière sous une forme de U, vue à partir du côté, à partir de l'extrémité libre de la première partie de bride, et la partie de raccord femelle est repliée vers le côté avant sous une forme de U, vue à partir du côté, à partir du côté arrière d'une partie d'extension qui fait saillie vers l'extérieur à partir de l'extrémité libre de la seconde partie de bride vers le côté arrière. L'inclinaison des parties d'extrémité des deux parties de raccord de cet empilement de tôles d'acier sous les formes de U respectives, et la disposition d'une partie saillante pour buter contre la partie de raccord femelle d'un autre empilement de tôles d'acier sur la première partie de bride, amène par conséquent les parties incurvées des deux parties de raccords mutuellement verrouillées à se réunir entre elles, et permet à la largeur des matériaux en forme de feuille constituant chacune des parties de raccord d'être réduite.
