In general, in the construction of stadiums, airports, bridges and structures, heavy steel structures are used in large quantities, and these steel structures are connected to the support or the ceiling by tension members such as high tensile tension bars and strands. At this time, the tension member used in the diameter is typically varied from tens of mm to hundreds of mm. The tension member is connected to the steel weight or support, a large tensile force is applied to the tension member by the weight of the steel weight, it is difficult to properly connect the tension member and the tension member by the weight of the tension member itself.

As the tension member is interconnected, a turnbuckle is employed. A turnbuckle is provided with through-holes formed with right and left threads at both ends, and the tension member and the tension member are interconnected by screwing the ends of the tension member to the turnbuckle. . The turnbuckle interconnecting the tension member and the tension member is then rotated or reverse rotated to pull the tension member and another tension member so that a predetermined tension force is applied to both tension members.

However, the tensile force acts in the direction of exiting the turnbuckle by the weight of the steel weight or the weight of the tension member itself, and thus a large friction force is applied between the screw of the turnbuckle and the screw of the tension member. The buckle must be rotated to pull the tension member and the tension member, but it is difficult to rotate the turnbuckle due to the frictional force as described above, and thus it is difficult to pull the tension member and the tension member so that a predetermined tension force is applied.
