In the method of holding in a fixed state, a case will be described in which, for example, a string provided between two columns separated at a predetermined interval is tensioned by using a string anchor. In this case, a string of necessary length is prepared in advance. This string is tied to one of the two posts at one end of the string prior to use of the string anchor. The other end of the string is connected to the first locking portion of the string locking device. At this time, the string is in a relaxed state. Then, the anchor for the string is passed through the other column, and the column is turned around as a turning point, and is moved in a direction approaching the one column side. In addition, an intermediate portion (hereinafter referred to as an outward string portion) from one of the struts to which the one end of the string is connected to the other strut, and the other strut are joined to the strap locking device from the folding point of the string. An intermediate portion (referred to as a “reverse string portion”) up to the other end of the string is located substantially in parallel.

度を増す。Next, the string locking device is slightly pulled in a direction away from the turning point so that the forward string portion is inserted into the first opening and the second stringing portion is inserted into the second opening. Thereafter, a moment about the rotation center axis of the second locking portion is given to the string locking device, and the string locking device is rotated clockwise by 180 °. With the rotation of the string locking device, the first locking portion presses the knot of the forward string portion against the return string portion and sets the distance between the first locking portion and the second locking portion clockwise as the rotation radius length. Rotate. As a result, the position of the portion that is locked by the second locking portion and the portion that is locked by the first locking portion of the double string portion are switched by 180 °. At this time, the forward string portion and the return string portion are entangled in the rotation direction of the first locking portion and the second locking portion by the rotation radius length, respectively, to reduce the length, and are pulled to reduce the tension. Increase.

Then, it is inserted into the second opening while tension by pulling the both in a perpendicular direction with lifting bunch overlapped and a recovery string portion forward string section which is in parallel position to each other, engaged with the third engaging portion. As a result, the forward string portion and the backward string portion are maintained in a state where a constant tension is applied to the string.

Also, in the second invention ,
To keep strained straps tense
Then, in addition to the string locking device used in the method of the first invention described above, a fourth locking portion, and one end of the third locking portion and one end of the fourth locking portion are connected to each other. A third opening forming a third opening in a U-shape
The use of the string locking device having the connecting portion allows the length of the turning radius to be longer than that of the method of the first invention due to the presence thereof, and accordingly, the rotating operation force (the second locking portion) (The force of giving a moment about the rotation center axis) can be reduced.

The method of holding the strain on the string is easy to apply and remove the strain on the string, improving the workability, and providing the string with the necessary tensioning action. , Which can be kept. Furthermore, the string in the slackened state of the second invention is tightly attached.
In the method of holding in a tensioned state, the string anchor used
The longer the radius of rotation (the distance from the second locking portion to the fourth locking portion corresponds to the length of the arm based on the principle of leverage), the longer the acting force (work required for the rotation operation based on the principle of leverage) Volume) can be reduced, which has the effect of making work easier.

挟持される。That is, with the rotation of the string locking device 1, the portion of the return string portion 2b that comes into contact with the first locking portion 10 via the knot 20 of the forward string portion 2a has a first locking portion. 10 is pulled in the rotation direction (see the arrow S1 in FIGS. 6 and 7), and the portion of the return string portion 2b that contacts the second locking portion 12 is rotated by the second locking portion 12 (see FIG. 6, see arrow S2 in FIG. 7), the lengths of which are each equal to the length of the turning radius are shortened, and tension is generated. In addition, outbound cord section 2a
Is a double string portion 2 which is located on the outer peripheral side while the knot 20 is rotated and moved by the rotation radius length together with the first locking portion 10.
As a result, the first locking portion 10 is wound around the first locking portion 10 so as to be covered, and is sandwiched between the first locking portion 10 and the return string portion 2b.

態が保持される。When the strap locking device 1 is rotated against the generated tension, the rotation radius length thereof (with respect to the distance L 1 from the first locking portion 10 to the second locking portion 12). The longer the distance L2 from the second locking portion 12 to the fourth locking portion 16 corresponds to the length of the arm based on the principle of leverage, the longer the acting force (work amount) required for the pivoting operation based on the principle of leverage. And the work becomes easier. Thereafter, the forward string portion 2a and the return string portion 2b where the workers are in parallel with each other (see FIGS. 6 and 7).
Second opening 1b side by lifting bunch overlapping bets, that is inserted through the second opening 1b while tensioned by pulling (downward direction in FIG. 6) the second end 120 side of the engaging portion 12. This second
The forward string portion 2a and the return string portion 2b are formed in the opening 1b by the second string.
When the opening 1b is inserted, it is once pulled obliquely downward, but since the forward string portion 2a is tied to the first locking portion 10, the
It does not come out of the locking part 10. Also, the return strap 2b is
Since it is locked to the retaining projection 10a of the locking portion 10,
It does not fall out of the first locking portion 10. Continue going string part 2a
And the return string portion 2b are connected to the third opening 1 through the third locking portion 14.
c and is locked by the fourth locking portion 16 (see FIGS. 8 and 9). Thereafter, when the worker releases the string locking device 1, the string 2 is maintained in a state in which a constant tension is applied.

済む。Further, by using the reverse operation procedure to the above-described case and applying the reverse rotation moment to the string stopper 1, the tension state of the string 2 is released and the string 2 can be loosened. Thus, according to the method of the present embodiment,
Long turning radius operating length from the rotation center at the time when the cord fastener 1 is to impart tension string 2, it requires only small operating force, becomes easy to be operated. Furthermore, the rotation of the string stopper 1 can be smoothly performed by the rotation moment. Then, the string locking device 1 can quickly and efficiently tension the string 2 and maintain and release this state. In order to release the locked state of the string 2, it is only necessary to perform the reverse operation procedure.
