摘要： PROBLEM TO BE SOLVED: To reduce bending deflection of a bolt in order to solve the following problems: when bending deflection occurs in the bolt due to bending vibration in a bolt fastening member of a machine or a construction structure, repetitive bending stress amplitude occurs in the bolt to reduce fatigue strength, and especially when a vibration close to natural frequency of the bolt is applied and the bolt resonates, the bending deflection increases and the repetitive bending stress amplitude also increases.SOLUTION: In the bolt fastening member, an opening between a bolt hole and a bolt is filled with a dilatancy fluid. The dilatancy fluid prevents the bolt from being rapidly deflected by the bending vibration, thereby reducing the repetitive bending stress amplitude of the bolt as a result.
摘要翻译：要解决的问题：为了减少螺栓的弯曲挠度，以解决以下问题：当由于机器的螺栓紧固构件或构造结构中的弯曲振动而在螺栓中发生弯曲偏转时，重复的弯曲应力在螺栓上发生振幅以降低疲劳强度，特别是当施加接近螺栓固有频率的振动并且螺栓产生共振时，弯曲偏转增加，并且重复的弯曲应力振幅也增加。解决方案：在螺栓紧固构件中，螺栓孔和螺栓之间的开口填充有膨胀流体。膨胀流体防止螺栓被弯曲振动迅速偏转，从而减少螺栓的重复弯曲应力振幅。版权所有（C）2013，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide the reliable screw-up structure which can release concentration of the stress to a valley bottom of a male screw to be generated when an excessive load and the tensile force are applied and which can prevent the generation of breakdown of a male screw side member and a draw-out of the male screw side member to maintain the excellent screw-up condition. SOLUTION: The male screw 2 has a screw surface formed to have a semi-circular cross section in an angle top 211 and the valley bottom 231 and a cross section formed of a straight line vertical to the screw axis in a flank 22 thereof. When a pitch of the male screw 2 is P, width of an angle 21 and a valley 23 of the male screw 2 are respectively 1/2P. The female screw 3 similarly has a screw surface formed to have a semi-circular cross section in an angle top 311 and a valley bottom 331 and a cross section formed of a straight line vertical to the screw axis in the flank 22. A valley width of the female screw 3 is formed a little larger than 1/2P, and an angle width of the female screw 3 is formed a little smaller than 1/2P. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To provide an anchor bolt capable of improving earthquake resistance through the improvement of retention yield strength of a column by enlarging the effective/shank cross-sectional area ratio of the anchor bolt to increase the elongation of a shank at the rupture of a fastening external screw part, thereby increasing absorbed energy until the rupture of the fastening external screw part. SOLUTION: The effective diameter de of a fastening external screw part 11A formed at the axial end part of a shank 10 by thread rolling is set to a value not smaller than the outer diameter dr of the shank 10 to enlarge an effective/shank cross-sectional area ratio Ra. This results in increasing the elongation L of the shank 10 at the rupture of the fastening external screw part 11A.
