ROLL MOLDING LIGHT-GAGE STEEL
To efficiently improve cross-sectional performance and workability compared to conventional lip channel steel, without changing a web size and flange size of the conventional lip channel steel that is generally distributed and adopted.SOLUTION: Roll molding light-gage steel enhances bending resistance of weak axis direction by attaching face bar or stiffener to the same, and uses when applying larger bending force than that of weak axis direction to strong axis direction. The roll molding light-gage steel includes, in lip channel cross-sectional shape, a web 2, flanges 3, lip parts 4, as well as acute angle ramps 5 that are folded to flange inner surface sides from each end of the lip parts and abut tips to flange inner surface. When comparing the roll molding light-gage steel with lip channel steel having one rank higher board thickness of lip channel steel in JIS specification, a second moment of area not required in the weak axis direction is low, but light-gage steel 1 having high second moment of area in the strong axis direction is obtained.SELECTED DRAWING: Figure 1
【課題】一般に流通され採用されている従来のリップ溝形鋼のウェブ寸法及びフランジ寸法を変えずに、従来のリップ溝形鋼よりも効率的に断面性能及び施工性を向上させる。【解決手段】弱軸方向の曲げ抵抗が面材又は補剛材がとりつくことによって補強され、強軸方向に弱軸方向よりも大きな曲げ力を受ける態様で用いられるロール成形軽量形鋼であって、 リップ溝形断面形状におけるウェブ２とフランジ３とリップ部４を有し、かつ、前記リップ部の端部からフランジ内面側に折り曲げられて先端がフランジ内面に突き当たる鋭角傾斜部５を有する断面形状である。ＪＩＳ規定のリップ溝形鋼における板厚が１ランク上のリップ溝形鋼と比較した場合、要求されない弱軸方向の断面二次モーメントは低いが、強軸方向断面二次モーメントの高い軽量形鋼１が得られる。【選択図】図１
