<p>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.</p> |
