This adjustment work is performed on the outer wall panels 100, 10 that are adjacent to each other in the horizontal direction.
This is a work in which the horizontal joints 101 are made to continue in a straight line by aligning the other one with one as a reference.

[Problems to be solved by the device]

However, when performing the adjustment work according to the conventional procedure, if the levelness of the outer wall panel 100 serving as a reference is not set with high accuracy, the levelness of the outer wall panel 100 adjacent to it is not accurately adjusted, and the horizontal joint 101 The result will be an upward or downward slope to the right. When such a situation occurs on each surface of the building H on which the outer wall panel 100 is constructed, a large step is generated in the horizontal joint 101 between the adjacent surfaces.

However, when setting the level of the reference outer wall panel 100, there was no appropriate means to set the level of the level, so even a fairly skilled person or experienced person should set the level with high accuracy. As a result, there has been a problem that it takes a lot of time and labor for the adjusting work as described above, and it is difficult to obtain a satisfactory finish.

This invention was made in view of the above problems and circumstances,
A thread for construction that enables a thread to be stretched horizontally by using a framework of a building, and enables adjustment work of horizontal joints by using the above-mentioned thread stretched horizontally as a standard of horizontality. The purpose is to provide a tension jig.

[Means for Solving the Problems]

The construction thread tension jig of the present invention comprises a scale plate having scales in the vertical direction, and a support plate portion to which the scale plate is attached and whose attachment level is variable with respect to the scale plate. At the same time, the jig main body is provided with a mounting plate portion having an inverted L-shaped cross section that is applied to the corner portion of the framework in the building, and the pointer corresponding to the scale plate is provided, and the mounting level for the support plate portion is variable. Is a slide plate,
A thread holder provided on the slide plate and capable of increasing / decreasing the amount of protrusion from the slide plate, and holes formed at a plurality of positions in the height direction of the shaft assembly through key holes formed in the jig body. A key for inserting the jig body into the shaft assembly by being inserted into an arbitrary hole selected from the parts.

[Action]

In the construction thread tension jig with the above-mentioned configuration, when the jig main body is applied to the corner of the framework of the building and the key is inserted into the hole of the above-mentioned framework through the key hole of the jig main body, the jig main body moves It is attached to the set. In that case, by selecting an arbitrary hole portion of the shaft assembly, the mounting level of the jig body is set to a level corresponding to the height of the selected hole portion.

Also, when the attachment level of the slide plate to the support plate of the jig body is changed, the height of the thread holder changes accordingly, and when the pointer of the slide plate is aligned with the scale of the scale plate of the jig body, the slide plate is moved. The mounting level of is accurately set to the level corresponding to the scale, and at the same time, the height of the thread holder is also accurately set to the height corresponding to the scale. In this way, the range in which the height of the thread holder can be set with high accuracy by adjusting the pointer to the scale moves up and down by changing the attachment level of the scale plate to the support plate portion of the jig body. Therefore, if the attachment level of the scale plate is changed and the pointer of the slide plate is adjusted to the scale of the scale plate, the height of the thread holder is adjusted in a wide range.

The above-mentioned thread tensioning jigs with the heights of the thread holders adjusted to the same height are installed at, for example, two or three or more building shafts at the same height, and the thread tensioning jigs If the threads are stretched between them, the threads become horizontal. Therefore, the horizontal joint is stretched with the position of the thread stretched horizontally as a reference, whereby the horizontalness of the horizontal joint is set with high accuracy.

Further, when the amount of width of the thread holder from the slide plate is increased or decreased, the thread tension position moves outward or inward.

When selecting the hole 120 of the axis 110, when the hole 120 is opened at the same height in each shaft set 110, the hole 120 of the same height may be selected. Further, when the hole 120 is not opened at the same height in each shaft 110, select the hole 120 opened as close as possible and select the difference in height between the holes 120. It is advisable to absorb it by adjusting the level of the thread holder 7 with respect to the jig body 1.

The level adjustment of the thread holder 7 with respect to the jig body 1 is performed by adjusting the attachment level of the slide plate 6 and the scale plate 4 with respect to the jig body 1. Since the adjustment operation of these mounting levels has already been described, the operation when the adjustment operation is performed will be described here.

That is, when the attachment level of the slide plate 6 to the support plate portion 2 of the jig body 1 is changed, the height of the thread holder 7 is changed accordingly, and the pointer 64 of the slide plate 6 is set to the scale 43a of the scale plate 4. When they are combined, the mounting level of the slide plate 6 is accurately set to the level corresponding to the scale 43a, and at the same time, the height of the thread holder 7 is also accurately set to the height corresponding to the scale 43a. In this way, the range in which the height of the thread holder 7 can be set with high accuracy by adjusting the pointer 64 to the scale 43a is
It moves up and down by changing the attachment level of the scale plate 4 to the support plate portion 2 of the jig body 1. Therefore,
If the attachment level of the scale plate 4 is changed and the pointer 64 of the slide plate 6 is adjusted to the scale 43a, the height of the thread holder 7 is adjusted in a wide range, and each thread is adjusted through such adjustment. Set the height of the thread holder 7 of the tension jig A to the water thread S
Can be set so that it is stretched horizontally.

Furthermore, the width of the thread holder 7 from the slide plate 6 is set to 4A.
It can be increased as shown, or conversely decreased as shown in FIG. 4B. Such adjustment of the amount of protrusion is necessary when the protrusion width of the outer wall panel 100 from the standing position of the frame 110 is different. The procedure for adjusting the width of the yarn holder 7 is as described above.
