LINEAR STEEL SHEET PILE, REINFORCEMENT STRUCTURE OF STRUCTURE USING THE LINEAR STEEL SHEET PILE AND REINFORCEMENT METHOD
PROBLEM TO BE SOLVED: To provide a linear steel sheet pile, a reinforcement structure of a structure using the linear steel sheet pile and a reinforcement method with a small joint shape (height) of a steel sheet pile, capable of increasing the workability when plating infilling concrete and structural reliability while ensuring the pull-durability of a joint fitting part.SOLUTION: In a linear steel sheet pile 1, the height g of the main catch of a joint is 6.0 mm or more; the ratio f3/f1 between the thickness f3 of the main catch and the web plate thickness f1 is 0.82 or more; the ratio f2/f1 between thickness f2 of a sub-catch and the web plate thickness f1 is 1.16 or more; the ratio c/f3 between the height c of a joint opening and the thickness f3 of the main catch is 1.25; and the distance h (effective height) from the center position of a web part 5 to the outermost edge of the sub-catch 3b is 40 mm or less.
【課題】鋼矢板の継手形状（高さ）を極力小さくして、充填コンクリート打設時の施工性および構造信頼性を向上させるとともに、継手嵌合部の引張り耐力が低下しない直線形鋼矢板、該直線形鋼矢板を用いた補強構造及び補強方法を得る。【解決手段】本発明に係る直線形鋼矢板１は、継手の主爪高gが6.0mm以上、主爪厚f3とウェブ部板厚f1の比f3／f1が0.82以上、副爪厚f2とウェブ部板厚f1の比f2／f1が1.16以上、継手開口高さcと主爪厚f3との比c／f3が1.25以上であり、ウェブ部５の中心位置から副爪部３ｂの最外縁までの距離h（有効高さ）が40mm以下であることを特徴とするものである。【選択図】 図１
