REPAIR STRUCTURE AND REPAIR METHOD FOR STEEL MEMBER
PROBLEM TO BE SOLVED: To provide a simple repair structure and repair method, in which drilling or welding is not performed to an existing steel member in which a crack occurs, and which can easily cope with a change in the plate thickness of a base material.SOLUTION: At a part of a steel member (crane girder 1), in which a crack C occurs, reinforcing members 31 are put into contact with both sides in the longitudinal direction of the steel member 1 across the crack C at an interval from each other, respectively. By clamping metal fittings 32 each having a body part 33 with a concavity 33a and two or more fastening bolts 34 for fastening the member caught in the concavity 33a at two or more places, the part in which the crack occurs and the reinforcing members 31 are caught in the concavities 33a and fastened by the fastening bolts 34, and the reinforcing members 31 on both sides in the longitudinal direction are connected to each other via a connection member 41.SELECTED DRAWING: Figure 3
【課題】亀裂が発生した既設の鋼部材に対して、孔開けや溶接を行わず、母材の板厚の変化にも容易に対応できる簡易な補修構造および補修方法を提供する。【解決手段】鋼部材（クレーンガーダー１）の亀裂Ｃが生じた部位の、亀裂Ｃを挟んで鋼部材１の長手方向両側に、それぞれ補強材３１が互いに隙間をあけて当接され、凹部３３ａを有する本体部３３と、凹部３３ａに挟んだ部材を２個所以上で締め付ける２つ以上の締め付けボルト３４とを備えた挟締金具３２によって、亀裂Ｃが生じた部位と補強材３１とが、凹部３３ａに挟まれて締め付けボルト３４で締め付けられ、長手方向両側の補強材３１同士が、連結部材４１を介して連結されている。【選択図】図３
