<Prior Art> Recently, prefabricated houses are becoming the mainstream not only as built-for-sale houses but also as custom-built houses because of their short construction period and relatively low material costs.

Assembling the unitized prefabricated wall includes, for example, a prefabricated wall of the first floor (hereinafter sometimes referred to as “first prefabricated wall”) and a prefabricated wall of the second floor (hereinafter referred to as “second prefabricated wall”). The second prefabricated wall is placed on the first prefabricated wall by a crane. In this case, the second prefabricated wall is usually placed slightly offset from the first prefabricated wall 1.

For this reason, it is necessary to perform the work of adjusting the displacement of the second prefabricated wall with respect to the first prefabricated wall, that is, the work of flushing the wall surfaces with each other.

<Problems to be Solved by the Invention> The flattening work between the wall surfaces is carried out between the first prefabricated wall 1 and the second prefabricated wall 3 as shown in FIG. The displacement of the second prefabricated wall 3 with respect to the first prefabricated wall 1 was adjusted by inserting the tip insertion portion 5a and twisting it upward or downward to shift the second prefabricated wall 3 rearward or forward. This misalignment adjustment work is troublesome and
As shown in the figure, the exterior material easily peeled off and collapsed.

In view of the above, the present invention provides a prefabricated wall misalignment adjusting tool that is easy to adjust the deviation of the second prefabricated wall and is less likely to damage the prefabricated wall, and a prefabricated wall assembling method using the auxiliary tool. The purpose is to provide.

<Means for Solving the Problems> The present invention solves the above problems by the following configurations.

The prefabricated wall displacement adjustment assisting tool according to claim 1 is a metal plate-shaped member, and has a mounting and fixing portion having a length shorter than a wall thickness of the prefabricating wall, and at least a longitudinal direction of the mounting and fixing portion. It is characterized by comprising an iron lever supporting portion formed on one side and having an iron lever inserting hole, wherein a boundary portion between the attachment supporting portion and the iron lever supporting portion is a weak portion due to a groove, a hole or the like. .

A method of assembling a prefabricated wall using the prefabricated wall displacement adjustment assisting tool according to claim 2, wherein the prefabricated wall on the side to be assembled (hereinafter referred to as "first prefabricated wall") is displaced with a predetermined pitch. A step of fixing the auxiliary tool through the attachment fixing part; a step of stacking and installing an assembling side prefab wall (hereinafter referred to as a "second prefab wall") on the first prefab wall; A step of inserting a bent portion of the iron lever into the iron lever support portion and adjusting the displacement of the second prefabricated wall by levering so that the second prefabricated wall does not shift relative to the first prefabricated wall; A step of assembling and fixing to one prefabricated wall by a fixing means; and a step of cutting and removing the iron lever supporting part of the auxiliary tool from the attaching and fixing part at the weakened part.

<Example> Hereinafter, the present invention will be described with reference to the drawings. The same parts as those of the conventional example are designated by the same reference numerals, and the whole or part of the description thereof will be omitted.

(1) FIG. 1 shows an example of a prefabricated wall misalignment adjusting aid used in the present invention.

Basically, it is a metal plate member made up of an attachment fixing portion 13 and an iron lever supporting portion 15 which is formed on at least one of the attachment fixing portion 13 in the front-rear direction and has an iron lever insertion hole 15a. is there. In the illustrated example, the iron lever supporting portion 15 is formed in both front and rear directions and has a strip shape as a whole, but in some cases, the iron lever supporting portion 15 may be one side or the iron lever supporting portion 15A. Is the second
As shown in the figure, it may be formed wider than the mounting and fixing portion 13A. A steel plate is usually used as the material of the metal plate.

The length of the mounting and fixing part is the first and second prefabricated walls 1, 3
It is slightly shorter than the wall thickness of. When the misalignment adjusting aid 11 is fixed to the first prefabricated wall 1, the boundary with the iron lever supporting part 15 is normally located within 2 to 3 mm from the side wall surfaces 1a and 1b of the prefabricated wall 1. Further, in the illustrated example, the attachment fixing portion 13 is formed with a fixing nail hole 13a with a predetermined pitch,
It is not necessary when fixing to the first prefabricated wall 1 by spot welding.

The outer peripheral shape and the hole shape of the iron lever supporting portion 15 are both rectangular in the illustrated example, but may be arbitrary such as triangular, trapezoidal, and round.

A fragile portion 17 is formed by a groove, a hole or the like at a boundary portion between the attachment fixing portion 13 and the iron lever supporting portion 15. Here, the groove is preferable because the cutting and removal of the iron lever supporting portion 15 can be performed neatly. The groove is formed on one side or both sides depending on the strength of the plate material.

(2) Next, a method for assembling the prefabricated wall using the above-mentioned misalignment adjusting tool will be described. The method of the present invention comprises the following steps.

Step of fixing the displacement adjustment assisting tool 11 to the upper end surface of the first prefabricated wall with a predetermined pitch via the mounting and fixing section 13 thereof: Here, the predetermined pitch is, for example, 1 to 1.5 m. Further, the fixing method is usually a nail, but when the upper end surface is made of a metal portion, spot welding may be used, and furthermore, it may be fixed by an adhesive agent. A strip seal 2 made of an elastic material is formed around the upper end joint surface of the first prefabricated wall 1, but the misalignment adjusting tool 11 is inserted into the slit formed in the strip seal 2 with a predetermined pitch. Becomes A screw plate 7 having a threaded eyebolt screw hole 7a is fixed to the corner portion of the upper edge of the first prefabricated wall 1, but the above-mentioned misalignment adjusting aid 11 has the same plate thickness as the plate 7. Is desirable. The mounting and fixing portion 13 of the misalignment adjustment assisting tool remains between the first and second prefabricated walls 1 and 2 and the plate 7 between the first and second prefabricated walls 1 and 2.
In addition to partially filling the space formed by the support of the second prefabricated wall to increase the strength, it also has a vibration damping effect.

Step of stacking and installing the second prefabricated wall on the first prefabricated wall: In this step, the second prefabricated wall 3 is suspended by a crane or the like via the eyebolt 8 screwed into the screw hole 7a.
At this time, the connecting bolt 9 of the first prefabricated wall 1 is inserted into the connecting hole (not shown) of the second prefabricated wall 3. In addition,
10 is a waterproof sheet that has been rolled up to the final process.

The second prefabricated wall is inserted into the iron lever supporting portion with a bent portion of the iron lever, and the second prefabricated wall is leveraged so that the wall surface of the second prefabricated wall is flush with the wall surface of the first prefabricated wall. Step of fine adjustment: Here, as the iron lever 21, one having one end serving as the bending pressing portion 21a is used. Further, as shown in FIG. 3, it is desirable to use an integrated pressing plate portion 22. It should be noted that, as shown in the example of FIG.
The fine movement adjustment work may be performed by bringing 25 into contact with each other. In addition, the deviation adjustment work can be similarly performed from the inside of the prefabricated wall.

Step of assembling and fixing the second prefabricated wall to the first prefabricated wall by fixing means: Usually, a coupling nut (not shown) is attached to the coupling bolt 9 inserted into the coupling hole 4 from the inner surface of the second prefabricated wall 3. Screw it in.

A step of cutting and removing the iron lever supporting portion of the displacement adjustment assisting tool from the mounting and fixing portion at the fragile portion: In this cutting and removing work, the fragile portion 17 is formed between the mounting and fixing portion 13 and the iron lever supporting portion 15. Therefore, the iron lever support portion 15 can be easily cut and removed from the attachment fixing portion 13 by hitting it with a hammer or the like.

When the waterproof sheet is held in the rolled-up state on the second prefabricated wall 3, the cut portion is located inside the wall, and thus the waterproof sheet is not hung up by hanging up the waterproof sheet. There is no danger of being damaged.

<Operation and Effect of the Invention> The prefabricated wall misalignment adjustment assisting tool and the prefabricated wall assembling method using the assisting tool of the present invention are configured as described above.
Since this method is used, fine adjustment work of the second prefabricated wall is easy and damage to the prefabricated wall is unlikely to occur. Furthermore, since the protruding portion (iron lever supporting portion) of the auxiliary tool remains between the wall joint walls without protruding from the wall surface of the prefabricated wall, there is no hindrance to the exterior or interior, and other members such as a waterproof sheet are used. There is no risk of scratching.
