Disclosed is a construction and method for jointing steel members using shear rings, achieving a jointing construction to which a real shearing force can be applied, improving working conditions, the jointing strength and durability, and reducing material. The construction has at least one first steel member and at least one second steel member overlapped together and respectively having at least a bolt hole and at least an annular groove, and at least one shear ring inserted in the annular groove of both the first steel member and the second steel member to prevent slip between the first steel member and the second steel member. The annular groove is formed at each of contact surfaces of the first steel member and the second steel member, and the bolt hole has a first clearance while the annular groove of at least one of the first steel member and the second steel member has a second clearance smaller than the first clearance. The second clearance allows a deformation or a displacement of the first steel member and the second steel member against an assembling force by the bolt and the nut until the bolt comes in contact with a side wall of the bolt hole.

La présente invention concerne une configuration et un procédé d'assemblage d'éléments en acier avec des anneaux de cisaillement, permettant de réaliser une configuration d'assemblage sur laquelle on peut appliquer un réel effort tranchant, dans le but d'améliorer les conditions de travail, d'améliorer la force et la durabilité du jointoiement, et de réduire la quantité de matériau utilisée. Cette configuration présente au moins un premier élément de construction en acier et au moins un second élément en acier qui se chevauchent et qui présentent respectivement au moins un trou de boulon, au moins une gorge annulaire, et au moins un anneau de cisaillement introduit dans la gorge annulaire à la fois du premier et du second éléments en acier, afin d'empêcher tout glissement entre les premier et second éléments en acier. La gorge annulaire est formée sur chacune des surfaces de contact des premier et second éléments en acier. Le trou de boulon présente un premier dégagement, alors que la gorge annulaire de l'un ou l'autre des premier et second éléments en acier présente un second dégagement inférieur au premier. Le second dégagement permet au premier et au second élément en acier de se déformer ou de se déplacer contre une force d'assemblage du boulon et de l'écrou, jusqu'à ce que le boulon vienne en contact avec la paroi latérale du trou de boulon.
