（産業上の利用分野）
この発明は銅線の歪、特にＰＣ鋼よシ巌の緊張管理に好
適な押ひ蓋測足方法に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for measuring strain on copper wires, particularly suitable for controlling tension in PC steel wires.
（背景仮術）
匠米、鋼線の止金測定するに龜銅線に嵌着したストレイ
ンゲージを用いるのが一般的である。(Background technique) To measure the fastening of steel wire, it is common to use a strain gauge fitted to the copper wire.
しかし、よシ線の伸びを測定する場合は各素線の１本に
ストレインゲージを接着するのであるが、素線か細いと
接着が１岨となり、少数の素線の伸びからよシ線全体の
伸びに換算することもあり、種度的にも良い結果を侍る
ことが難しくなる。また、異形線の場合は凹凸のピッチ
が小さいとき１Ｊゲージを接血することができなかった
。However, when measuring the elongation of a straight wire, a strain gauge is glued to one of each wire, but if the wire is thin, the bonding will be 1 g, and the elongation of a few wires will measure the entire wire. This can also be converted into elongation, making it difficult to achieve good results in terms of variety. In addition, in the case of irregularly shaped wires, it was not possible to weld 1J gauge when the pitch of the unevenness was small.

画定方法を得ようとするものである。On the other hand, in the PCI method, it goes without saying that it is desirable to create elongated lines from valley to valley in order to manage the tension at the edges of PC copper. Because of the serious situation, dozens of V Mukotake t1 were used with Otani Kanυ load cell.
(Purpose of the invention) In this invention, since the strain gauge is connected directly to the horizontal line or the straight line, there is no strain gauge attached to these lines. It is an object of the present invention to provide a method for determining the elongation of steel which does not have the above-mentioned drawbacks and allows a strain gauge to be easily attached by attaching it to the second side of the sleeve.
（発明″ｇ）構成と効果） 以下、この発明を図面を参照して詳細に説明する。(Invention “g) Structure and effect) Hereinafter, the present invention will be explained in detail with reference to the drawings.

ード紛６の挿吐孔である。FIG. 1 is a cross-sectional view of one embodiment of the sleeve used in the present invention. A sleeve body 1 has a hole 2 for inserting a copper plate, etc., and has a thousand-faced part 3 near the center of the outer surface. The adhesive portion of the strain gauge 4 is formed. 5 is a hole for inserting and discharging the 4V lead powder 6.

第１図示のスリーブ構造が望ましい。The stress distribution of the sleeve crimped in the same way as described above is as shown in Figure 5. It is low at both ends and becomes even more at the center, υ, and the gage bonding position is almost constant at the center of the sleeve. The sleeve structure shown in Figure 1 is desirable from the viewpoint of specifying the bonding position.
