Prepare for the department.

  The support 3 includes a pile insertion portion 7 through which the pile P is passed, and a substantially rectangular block portion 9 fixed to the pile insertion portion 7. The pile insertion portion 7 is a substantially C-shaped cylinder in plan view. Specifically, the pile insertion portion 7 has a substantially C-shape in plan view in which a part of a peripheral wall of a substantially short cylindrical material that opens in the up-down direction is cut out in the axial direction, and radially from both open ends. Rectangular plate-like engagement pieces 11 and 13 are formed extending outward. Of the pair of engaging pieces 11 and 13, one engaging piece 11 is formed with a round hole 11 a penetrating in the thickness direction. The other engagement piece 13 is formed with a screw hole 13a coaxially with the round hole 11a of one engagement piece 11.

  Then, when the first bolt 15 is passed through the round hole 11a of one engagement piece 11 and screwed into the screw hole 13a of the other engagement piece 13, the engagement pieces 11 and 13 come close to each other, and thus The pile insertion part 7 is slightly reduced in diameter. As the first bolt 15, an operation bolt such as a knob bolt, a grip bolt or a butterfly bolt is preferably used, and a knob bolt is used in the illustrated example.

  The block portion 9 is fixed to the outer peripheral surface of the center portion in the circumferential direction of the pile insertion portion 7. The block portion 9 has a tip end surface 9a formed in an arcuate surface corresponding to the outer peripheral surface of the pile insertion portion 7, and a central portion in the vertical direction is cut into a groove shape in a substantially semicircular shape along the width direction. Thus, a groove portion 9b is formed. The block portion 9 has its tip end surface 9 a abutted against the central portion in the circumferential direction of the pile insertion portion 7 and is fixed by welding. Further, the block portion 9 is formed with a screw hole 9c from the central portion of the base end surface thereof toward the distal end side, and the screw hole 9c opens in the groove portion 9b.

The fixture 5 is a rectangular plate piece, which is a metal piece in this embodiment. A plurality of round holes and / or long holes are formed in the fixture 5 at appropriate intervals. In the illustrated example, the attachment 5 is formed with a round hole 21 penetrating in the thickness direction at the center in the longitudinal direction.
In the state shown in FIG. 1, the fixture 5 has a long hole 23 formed in the longitudinal direction on the left side of the round hole 21 in the center in the longitudinal direction, and the round hole 25 is formed on the left side of the long hole 23. Is formed. Further, a long hole 27 that is long in the longitudinal direction is formed on the left side of the round hole 25. Thereby, in a present Example, the area | region in which the hole is not formed remains on the right side from the round hole 21 of the longitudinal direction center part of the fixture 5. FIG.

  The attachment 5 is attached to the support 3 by the second bolt 31 being screwed into the screw hole 9 c formed in the block portion 9 through any of these holes 21, 23, 25, 27. . As the second bolt 31, an operation bolt such as a knob bolt, a grip bolt, or a butterfly bolt is preferably used. In the illustrated example, a knob bolt is used.

Moreover, the fixture 5 can be rotated around the bolt by passing the second bolt 31 through the round holes 21 and 25 or the long holes 23 and 27. However, the rotation of the fixture 5 is restricted by tightening the second bolt 31 on the support 3.
Furthermore, since a plurality of round holes 21 and 25 or long holes 23 and 27 are formed in the fixture 5 along the longitudinal direction, the second bolt 31 is placed in any of the holes 21, 23, 25, 27. The attachment position of the attachment 5 with respect to the support 3 can be changed by passing through.
At that time, in the case of the long holes 23 and 27, the position of the fixture 5 relative to the support 3 can be arbitrarily adjusted by moving the second bolt 31 along the long holes 23 and 27. Therefore, the short sides (sides along the short direction) 5a, 5b of the fixture 5 can be easily brought into contact with the wall surface.

In FIG. 1, among the long side portions (sides along the longitudinal direction) 5c, 5d of the fixture 5, a plurality of yarn hooking portions 33 are formed on one long side portion 5c at regular intervals in the longitudinal direction. ing. The thread hook 33 is formed by a notch or a notch. The shape of the notch or notch is not particularly limited, but is formed in a small pentagonal shape in the illustrated example.
Specifically, in FIG. 1, a substantially rectangular notch is formed to open to the upper end side 5 c of the fixture 5, and the lower end portion of the notch is formed in a substantially V shape, whereby the notch 33 is formed in a pentagon shape as a whole.
Accordingly, the notch 33 is formed with a pair of vertical sides extending vertically downward and spaced apart in the longitudinal direction of the fixture 5 in a state in which the long side portion 5c of the fixture 5 is horizontally disposed, An inclined side that inclines in the longitudinal direction of the fixture 5 as it goes downward from the lower end portion.

  In this embodiment, the opening width a at the top of the pentagonal cutout 33 is about 2 mm, and the depth b is about 2 mm. The interval (pitch) c between the bottoms of adjacent notches 33 is about 10 mm.

  Preferably, one or a plurality of thread hooks 35 are also formed on the short sides 5a and 5b of the fixture 5. In the illustrated example, two pentagonal cutouts 35 are formed in the short sides 5a and 5b so as to be spaced apart in the short direction (vertical direction in FIG. 1).

The water stringer 1 of this embodiment having such a configuration is used by being attached to a pile P driven into the ground.
Specifically, by screwing the first bolt 15 from one engagement piece 11 to the other engagement piece 13 in a state where the pile insertion part 7 of the support 3 is passed through the pile P driven into the ground. The support 3 is fixed to the pile P. In this embodiment, the support 3 can move up and down with respect to the pile P until the first bolt 15 is screwed and tightened. The support 3 may be fixed to P.
And what is necessary is just to hang and attach to the fixture 5 so that the one end part of the water thread | yarn 41 may pass the notch 33. FIG. For example, as shown in FIG. 2, each pile P is driven near the corner of the site, and the water string tensioner 1 of this embodiment is attached to each pile P, and water is attached so as to bridge the fixtures 5 and 5 together. The thread 41 may be stretched. In addition, although the pile P can use various piles, it is preferable to use a metal pile.

In this embodiment, as shown in FIG. 5, the fixture 5 is turned upside down from the state shown in FIGS. 1 and 3, and one end of the water thread 41 passes through the notch 35 of the fixture 5. Thus, it is also possible to stretch the water string 41 along the longitudinal direction of the fixture 5 by being hung around the short sides 5a and 5b. Further, one end of the water thread 41 is looped and hooked on the notch 35 of one of the short sides 5a and 5b, and the water thread 41 is placed on the other long side 5d of the fixture 5. Alternatively, it is possible to stretch the water string 41 along the longitudinal direction of the fixture 5 in contact with or close to the side surface of the fixture 5. Thus, the attachment method of the one end part of the water string 41 to the fixture 5 is arbitrary.
In the present embodiment, the notches 33 and 35 of the fixture 5 are formed in a pentagonal shape, so that, for example, one end of the water string 41 is hooked and hooked on the notch 35, so that the longitudinal direction of the fixture 5 is increased. Even when the water string 41 is extended along, there is no possibility that the water string 41 will come out of the notch 35.

The water string tension tool 1 of the present embodiment can stretch the water string without using a nail, and it does not take time and effort. Moreover, the water stringing tool 1 of the present embodiment can be reused, the cost can be reduced, and the environment is friendly. In this embodiment, no hole is formed in substantially half of the fixture 5. That is, in FIG. 1, since no hole is formed on the right side of the round hole 21 at the center in the longitudinal direction, it is possible to fill in this portion with a pen or the like.
Furthermore, in the present embodiment, the attachment angle of the attachment 5 with respect to the support 3 can be arbitrarily changed, so that the attachment 5 can be fixed to the support 3 at an angle corresponding to each site. At this time, for example, when it is desired to arrange the fixture 5 horizontally, a level can be attached to the fixture 5 and the fixture 5 can be fixed to the support fixture 3 in a horizontal state.

  Next, a modified example of the water string tensioner of the present invention will be described. In addition, since the water string tensioner of the present modification has basically the same configuration as that of the above embodiment, the following description will focus on the different parts, and the same portions will be denoted by the same reference numerals. I will explain.
