GROOVED LIGHTWEIGHT SECTION STEEL
PROBLEM TO BE SOLVED: To provide a grooved lightweight section steel that improves flexural rigidity and buckling yield strength of a structural member formed by making a pair of grooved lightweight section steels into a back-to-back state, and can achieve rational and economical design based on the magnitude of stress generated.SOLUTION: A grooved lightweight section steel 1 applying the present invention extends in a depth direction at a predetermined cross-sectional shape, and includes: a pair of flanges 2 extending to a width direction X; a web 3 extending in a height direction Y at the side of one side edge 2a of the width direction X of the pair of flanges 2; and an erection part 4 erected from the web 3 to the flange 2. In the web 3, any one or both ends of the height direction Y are disposed at intervals S from the flange 2 proximal to the end of the web 3 to the height direction Y. The erection part 4 extends at a slant so as to be separated from one side edge 2a of the width direction X of the flange 2 from the end of the web 3 to the flange 2, and is joined to the flange 2 by welding.SELECTED DRAWING: Figure 3
【課題】一対の溝形軽量形鋼を背中合わせにした構造部材の曲げ剛性と座屈耐力を向上させて、また、発生する応力の大きさに応じた合理的で経済的な設計を実現することのできる溝形軽量形鋼を提供する。【解決手段】本発明を適用した溝形軽量形鋼１は、所定の断面形状で奥行方向に延びるものであり、幅方向Ｘに延びる一対のフランジ２と、一対のフランジ２の幅方向Ｘの一方の側端２ａ側で高さ方向Ｙに延びるウェブ３と、ウェブ３からフランジ２まで架設される架設部４とを備える。ウェブ３は、高さ方向Ｙの何れか一方又は両方の端部が、ウェブ３の端部に近接するフランジ２から、高さ方向Ｙに間隔Ｓを空けて配置される。架設部４は、ウェブ３の端部からフランジ２まで、フランジ２の幅方向Ｘの一方の側端２ａから離間するように傾斜して延びて、フランジ２に溶接により接合される。【選択図】図３
