A type of fastener used to tighten and eliminate slack in steel cables stretched between two points. There are threaded rods on the left and right, and the threaded parts are connected with a common nut. The male threads on one side are right-handed and the male threads on the other are left-handed. When the female threaded part, i.e. the nut, is rotated, the two male threads move closer to each other, and when the rotation is reversed, they move apart. If a turnbuckle is placed between the pillars of a structure and the supporting steel cables, the cables can be tightened by rotating it.

2点間に張った鋼索などのたるみをなくし、引き締めるのに使用される締め具の一種。左右にねじ棒があり、ねじ部が共通のナットで連結されている。一方の雄(お)ねじは右ねじで、他方の雄ねじは左ねじとなっている。雌(め)ねじのある部分、すなわちナットを回転すると、二つの雄ねじは互いに接近し、回転を逆にすると遠ざかる。構造物の支柱、支持鋼索の中間にターンバックルを入れておくと、これを回転することによって鋼索を強く緊張させることができる。 [中山秀太郎] ©Shogakukan"> ターンバックル 出典 小学館 日本大百科全書(ニッポニカ)日本大百科全書(ニッポニカ)について 情報 | 凡例 |
