PROBLEM TO BE SOLVED: To solve the following problem that a deformed bar has rotation proneness and low adhesion to concrete even when a protrusion such as a rib and a knot is attached to a surface of the deformed bar in the case where a cross-section is circular, though the deformed bar basically has a round bar shape and a circular cross-sectional shape.SOLUTION: A deformed bar has a triangular cross-sectional shape. Thus, the deformed bar can hardly be rotated, and can hardly be separated by making adhesion to concrete higher.SELECTED DRAWING: Figure 1
【課題】異形棒鋼は、丸棒タイプが基本形状であり、その断面は円形が基本である。しかしながら、断面が円形であると、異形棒鋼の表面にリブや節の突起を付けても、回転しやすくコンクリートとの密着力、付着力が弱い点があった。【解決手段】異形棒鋼の断面形状を三角形にすることにより、回転しにくくし、コンクリートとの密着力、付着力をより強力にし、剥離しにくくする。【選択図】図１
