    Abstract: PURPOSE: A PC(Prestressed concrete) steel wire using a deformed rod is provided to prevent a slip by forming a 3-way indent on the surface of a rod composing a PC steel wire and to improve adhesive power with concrete according to an increase in surface area. CONSTITUTION: In a PC steel wire using a deformed rod, a deformed rod(1) comprises a trio indent line(IL) formed at an angle of 120 degrees on the outside longitudinally, and a unit indent of each indent line(IL), as an oval, is formed to be inclined toward the direction of the length(P). If the diameter(D) of the deformed rod(1) is 5.0¯5.5 millimeters, the depth(t) of the unit indent is 0.02¯0.05 millimeters, the width(n) is approx. 5¯6 millimeters and an interval(p) between unit indents is 2¯3 millimeters.

    Abstract: PROBLEM TO BE SOLVED: To prevent the movement of a core wire and the loosening of a steel cord. SOLUTION: The steel cord is constituted as follows. A side wire sw is preformed into a helical shape by running the side wire sw along a plurality of pins arranged with difference of elevation in a preformer. The resultant side wire is twisted by prescribed turns in the same direction as the twisting direction of a strand to be twisted at a twisting machine, and twisted back by the prescribed turns to impart a residual turning stress in the same direction as the twisting direction to the side wire sw in a turning stress-regulating device. The steel cord tw is formed by twisting the core wire cw with the side wire sw by the twisting machine. The preformed rate of helical preforming is 70% or more and less than 100%, and the residual turning stress is preferably 2 turns or more and 4 turns or less. COPYRIGHT: (C)2009,JPO&INPIT

    Abstract translation: 要解决的问题：防止芯线的移动和钢丝绳的松动。 解决方案：钢帘线的构成如下。 通过沿着预成型机的不同高度布置的多个销子运行侧线sw来将侧线sw预成螺旋状。 所得到的侧线以与扭绞机扭转的绞合线的扭转方向相同的方向扭转规定的匝，并且扭转规定的匝数，以在与扭转方向相同的方向上产生残余的转动应力，从而 转向应力调节装置中的侧线sw。 钢绞线tw是通过扭绞机将芯线cw与侧线sw进行扭转而形成的。 螺旋预成型的预成形率为70％以上且小于100％，残余转弯应力优选为2匝以上且4匝以下。 版权所有（C）2009，JPO＆INPIT
