PURPOSE:To obtain a shape steel for steel-made continuous wall, in which the smooth outer wall surface can be formed and two kinds of the shape steels for steel-made continuous wall are unnecessary and the producing method is easy, by arranging joint parts having smooth web part and specified asymmetrical shapes at the right and the left sides. CONSTITUTION:The shape steel 30 for steel-made continuous wall is provided with a linear web part 31 having almost smoothness of at least one side surface, an upper claw 35 linearly extended with the web part at the one end of the web part 31 and a lower claw 34 bending as arc state at the below part of the upper claw 35 to constitute a first joint part 33 formed with an opening part 36 opened outward with these upper claw 35 and lower claw 34. Further, at the other end of the web part 31, almost an arc state upper claw 39 formed at the below part by the thickness of the upper claw 35 of the first joint part 33 and a lower claw 38 bent as arc state at the below part of the upper claw are provided to constitute a second joint part 37 formed with an opening part 40 between the upper claw 35 and the lower claw 38. In this way, as the joint parts having the specific asymmetrical shapes at the right and left sides are arranged, the separated joints as the conventional method are necessary, and the shape steel for continuous wall can directly be connected with the same shape steel. |
