JOINT STRUCTURE OF CHANNEL-SHAPED STEEL
To provide a joint structure of channel-shaped steel which has joint strength equivalent to that of a conventional joint structure of channel-shaped steel, can reduce the number of components, facilitates joint construction, and can make the surface side of a flange flat.SOLUTION: There is provided a joint structure of channel-shaped steel for joining a channel-shaped steel 10 and a steel material 14 having a plate part 15. Thicknesses of a flange 12 and a web 13 of the channel-shaped steel are substantially the same. When a connection plate for connecting the web 13 of the channel-shaped steel and the plate part 15 of the steel material is joined by bolts 6, or when the web 13 of the channel-shaped steel and the plate part of the steel material are joined by the bolts 6, a constraint length (ls) of the connection plate or the plate part 15 of the steel material to the longitudinal direction of the web 13 of the channel-shaped steel is defined as a constraint length (ls) determined by the following expression (1). Expression (1): ls≥b×√3 (where b represents flange width).SELECTED DRAWING: Figure 6
【課題】従来の溝形鋼の接合構造と同程度の接合強度を有するとともに、部品点数を少なくでき、接合施工が容易であり、さらにフランジの表面側をフラットにすることが可能な溝形鋼の接合構造を提供すること。【解決手段】溝形鋼１０とプレート部１５を有する鋼材１４を接合する溝形鋼の接合構造であって、溝形鋼のフランジ１２とウエッブ１３の厚みが実質的に同じ厚みであり、溝形鋼のウエッブ１２と鋼材のプレート部１５とを繋ぐ連結プレートが、ボルト６により接合される場合、又は溝形鋼のウエッブ１３と鋼材のプレート部が、ボルト６により接合される場合に、溝形鋼のウエッブ１３の長手方向に対する連結プレート、又は鋼材のプレート部１５の拘束長さ（ｌｓ）を下記式（１）により求められる拘束長さ（ｌｓ）としたことを特徴とする。ｌｓ≧ｂ×√３・・・（１）（式中、ｂはフランジ幅を表す）【選択図】図６
