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, has first gap between bolt hole and the bolt, at least one anti-shear ring inserts in the cannelure of the described first steel member and the second steel member, prevent slip between the first steel member and the second steel member with screw bolt and nut, between the cannelure of one of the first steel member and second steel member and described anti-shear ring, have second gap less than described first gap;

    It is characterized in that;

    described second gap allows distortion that the first steel member and second steel member opposing keyhole produces with the fastening force of bolt and mobile, up to a preset limit, described second gap allows after arriving described preset limit by distortion or the mobile shearing resistance that is applied on the described anti-shear ring, the sidewall of described bolt and described bolt hole contacts when described preset limit, described anti-shear ring has the central side wall surface, described central side wall surface contacts with at least a portion of the sidewall of the described first steel member or the second steel member along the vertical direction of the described first steel member and the contact surface of the second steel member, when distortion with move caused the contact when occurring in second gap, the shearing resistance of reality is applied on the anti-shear ring.
