1. structure of using anti-shear ring to connect some steel members, described structure comprises:

  • At least one first steel member and at least one second steel member overlap, the first steel member and the second steel member have at least one bolt hole and at least one cannelure separately, this bolt hole forms by each the first steel member and the second steel member, cannelure is formed on each contact surface of the first steel member and the second steel member, be inserted through bolt hole and come the fastening first steel member and the second steel member of making to link together by means of at least one bolt by means of nut, bolt hole has first gap, the cannelure of a member in the first steel member and the second steel member has second gap less than first gap, and at least one anti-shear ring is inserted in the cannelure of the first steel member and the second steel member, thereby prevent between the first steel member and the second steel member, to slide with screw bolt and nutIt is characterized in that;

    second gap allows the fastening force of the first steel member and second steel member resistance screw bolt and nut and is out of shape or moves, till reaching preset limit, and after reaching preset limit second gap by means of this distortion or move shearing force is applied in the anti-shear ring, bolt contacts with the sidewall formation of bolt hole at the preset limit place, variations in temperature, static load, vibration, earthquake, dynamic loads etc. produce this distortion or move, anti-shear ring has the central side wall surface that is arranged on the anti-shear ring sidewall surfaces, the central side wall surface with up and down from the contact surface of the first steel member and the second steel member, at least a portion of the first steel member and each sidewall of the second steel member forms and contacts, thereby when occurring in second gap, actual shearing force is applied in the anti-shear ring by distortion or mobile caused contact.
