STEEL MEMBER REINFORCEMENT STRUCTURE AND REINFORCEMENT METHOD
To suppress the occurrence of fatigue cracking in an H-beam by appropriately reducing stress applied on the H-beam serving as a crane girder.SOLUTION: The reinforcement structure of an H-beam serving as a crane girder for supporting a mobile body on an upper surface is formed such that a reinforcement member is provided to the bottom surface of the H-beam, and slits are formed in the lower flange of the H-beam from the short-direction end of the lower flange toward a web of the H-beam. A plurality of slits are formed so as to sandwich the web of the H-beam along the longitudinal direction of the lower flange of the H-beam.SELECTED DRAWING: Figure 8
【課題】クレーンガーダーとしてのＨ形鋼に発生する応力を適切に低減させ、当該Ｈ形鋼への疲労亀裂の発生を抑制する。【解決手段】上面で移動体を支持するクレーンガーダーとしてのＨ形鋼の補強構造であって、前記Ｈ形鋼の下面には補強部材が設けられ、前記Ｈ形鋼の下フランジには、当該下フランジの短手方向端部から前記Ｈ形鋼のウェブに向けてスリットが形成されている。スリットはＨ形鋼の下フランジの長手方向に沿って、Ｈ形鋼のウェブを挟んで、複数形成されている。【選択図】図８
