BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a house unit installation and adjustment jig used when constructing a unit house.

0002

2. Description of the Related Art A unit house is constructed by connecting house units assembled in a factory front to back, left to right, or top to bottom on site. In this case, it is necessary to adjust the installation position of each house unit so that the gaps between the house units are constant and the sides of adjacent house units are aligned.

[0003] Conventionally, as an installation adjustment jig for a house unit, the one described in Japanese Patent Publication No. 55-32135, for example, is known. In this installation adjustment jig, a pair of threaded portions whose winding directions are opposite to each other are formed on the guide rod, and a leg member for locking the house unit is screwed into each of these threaded portions. Then, the locking pin protruding from this locking leg member is engaged with the locking hole formed in the pillar or beam of the house unit, and in this state, a rotary tool such as a torque wrench with a ratchet is attached to the guide rod. The guide rod is rotated by engaging with a hexagonal portion formed at one end, and the pair of locking leg members are moved toward or away from each other, thereby moving the house unit and adjusting the installation position. there were.

0004

[Problems to be Solved by the Invention] However, the conventional installation adjustment jig as described above has the following problems.

[0005] Since the hexagonal part for engaging a rotary tool such as a torque wrench with a ratchet was formed only at one end of the guide rod, the rotational force from the rotary tool was input only from one end of the guide rod. This may cause the guide rod to be twisted and require a large force to rotate the guide rod, making the work difficult.

Furthermore, since the locking leg member only has a locking pin projecting thereon as a locking member for the house unit, a locking hole for engaging this locking pin is not formed. This installation adjustment jig could not be used at the location.

[0007] Furthermore, in terms of strength, it is desirable that the locking hole for inserting the locking pin of the installation adjustment jig be formed in the area where the beam and the joint piece (used for joining the column and beam) overlap. However, when joining a beam and a joint piece by welding or the like, there are cases where the holes in the beam and the holes in the joint piece do not overlap concentrically due to dimensional errors. In conventional installation adjustment jigs, the locking pin is formed into a cylindrical shape with a single diameter, so the locking pin cannot be inserted into a non-circular locking hole, making it impossible to use the installation adjustment jig. .

[0008] The present invention has focused on the above-mentioned conventional problems, and the first object is to enable the guide rod to be easily rotated from both ends. The second challenge is to make it possible to use the installation adjustment jig even in places where there is no installation adjustment jig, and even if the actual shape of the locking hole is different from the shape of the locking pin, The third challenge is to make it possible to insert pins.

[0009]

[Means for Solving the Problems] In order to solve the first problem, in the house unit installation adjustment jig according to claim 1, a pair of screws whose winding directions are opposite to each other are provided on the guide rod. In the installation adjustment jig for a house unit, in which leg members for locking the house unit are screwed into each of these threaded parts, screws for engaging a rotary tool are provided at both ends of the guide rod. It has a configuration in which a hexagonal part is formed.

[0010] Furthermore, in order to solve the above second problem,
In the house unit installation adjustment jig according to claim 2, the guide rod is formed with a pair of threaded portions whose winding directions are opposite to each other, and each of these threaded portions is provided with a leg member for locking the house unit. In the installation adjustment jig for a house unit, which is screwed together, a locking groove capable of engaging with a beam of the house unit is formed on the opposing side surfaces of both of the locking leg members.

[0011] Furthermore, in order to solve the above third problem,
In the house unit installation adjustment jig according to claim 3, the guide rod is formed with a pair of threaded portions whose winding directions are opposite to each other, and each of these threaded portions is provided with a leg member for locking the house unit. In the installation adjustment jig for the house unit, in which the locking leg members are screwed together, a locking pin that can be inserted into a locking hole formed in the house unit is provided protruding from both of the locking leg members, and the locking pin is inserted into a locking hole formed in the house unit. It has a configuration in which a tapered portion is formed at the tip.

0012

[Function] In the house unit installation adjustment jig according to claim 1, since hexagonal parts for engaging a rotating tool are formed at both ends of the guide rod, a torque wrench or the like with a ratchet is attached to both ends of the guide rod. A rotating tool can be engaged. Therefore, since the rotational force from the rotary tool is input from both ends of the guide rod, the guide rod is not twisted, and the guide rod can be easily rotated with a small force.

In the house unit installation adjustment jig according to claim 2, the locking groove is formed on the opposite side surface of the locking leg member so that the locking groove can be engaged with the beam of the house unit. By engaging with the beam of the house unit, the installation adjustment jig can be used even in locations where a locking hole for engaging the locking pin is not formed.

In the house unit installation adjustment jig according to claim 3, the locking leg member has a locking pin protrudingly provided to engage with a locking hole formed in the house unit. Since a tapered part is formed at the tip of the pin, even if the actual shape of the locking hole is different from the shape of the locking pin, the tapered part can be inserted into the locking hole and hooked. .

1 is formed to protrude beyond the groove lower edge 272.

Next, a method for installing and adjusting a house unit using the installation adjustment jig will be described based on FIGS. 3 to 5.
I'll explain it to you.

The first adjustment method is to insert each parent locking pin 25 of the installation adjustment jig G into the locking hole 31 of the pillar 3, as shown in FIG. The guide rod 1 is rotated by engaging the jig with hexagonal parts 12 formed at both ends of the guide rod 1. In this case, when the guide rod 1 is rotated in a direction in which the locking leg members 2 approach each other, the interval between the house units U becomes narrower, and when the guide rod 1 is rotated in a direction in which the locking leg members 2 are moved away from each other, the distance between the house units U becomes smaller. unit U
The distance between is widened. Note that this adjustment method can be applied to position adjustment between the house units U, U, in which the locking hole 31 is formed at the upper end of the pillar 3, and can be applied to the position adjustment between the adjacent house units U,
It is possible not only between U and U, but also between U and U located at opposing positions.

The second method of use is to use the pedestal 22 interposed between the block body 21 and the parent locking pin 23, as shown in FIG.
The locking groove 27 formed in the guide rod 1 is engaged with the upper edge of the beam 2, and in this state, the rotation jig is engaged with the hexagonal parts 12 formed at both ends of the guide rod 1 to rotate the guide rod 1. . In this case, since the upper groove edge 271 of the locking groove 27 is formed to protrude more than the groove lower edge 272, the locking groove 27 can be easily engaged with the upper edge of the beam 2 using the groove upper edge 271 as a guide. can. In addition, this adjustment method can be applied to the position adjustment between adjacent house units U, U, and the columns 3 and beams 4 of house unit U.
, 5 is not provided with a locking hole, or even if there is a locking hole, its size does not match the size of the parent locking pin 23 or the grandchild locking pin 25. However, this is an adjustment method when it is necessary to adjust the direction in which the locking groove 27 of the pedestal 22 and the upper edges of the beams 4 and 5 do not come out of engagement, that is, the direction in which the distance between the house units U and U is narrowed.

The third adjustment method, as shown in FIG. 5, is to insert each sub-locking pin 25 of the installation adjustment jig G into the locking holes 41 and 61 of the beam 4 and the joint piece 6, and rotate in this state. The guide rod 1 is rotated by engaging the jig with hexagonal parts 12 formed at both ends of the guide rod 1. In this case, as shown in FIG. 6, the locking hole 41 of the beam 4 and the locking hole 61 of the joint piece 6
Even if they do not overlap concentrically and the actual shape of the locking hole is different from the shape of the child locking pin 25, the child locking pin 2
Since the tapered part 26 formed at the tip of the housing unit 5 can be inserted into the locking holes 41 and 61 and hooked on the house unit U, the distance between the housing units U and U can be adjusted by rotating the guide rod 1. Can be adjusted. Note that this adjustment method can be applied to position adjustment between the house units U and U in which the locking holes 41 (locking holes 51) and 61 are formed in the beam 4 (beam 5) and the joint piece 6. , is possible not only between adjacent house units U, U, but also between house units U, U located at opposing positions.

Furthermore, the installation adjustment jig G of this embodiment has hexagonal parts 12 for engaging a rotary tool formed at both ends of the guide rod 1, so that any of the above-mentioned first to third adjustments can be performed. Even when this method is adopted, a rotary tool can be engaged with both ends of the guide rod 1. Therefore, since the rotational force from the rotary tool is input from both ends of the guide rod 1, the guide rod 1 is not twisted, and the guide rod 1 can be easily rotated with a small force.

Although the embodiments of the present invention have been described above in detail with reference to the drawings, the specific configuration is not limited to these embodiments, and the design may be changed without departing from the gist of the present invention. are also included in the present invention. For example, as a modification of the adjustment method using the parent locking pin 23, one parent locking pin 23 is inserted into the locking hole 31 of the pillar 3, and the other parent locking pin 23 is inserted into the locking hole 31 of the beam 4 and the joint piece 6. Stop hole 41,6
1 is also possible. Similarly, as a modification of the adjustment method using the grandchild locking pin 25, one of the grandchild locking pins 25 is inserted into the locking hole 31 of the pillar 3, and the other grandchild locking pin 25 is inserted between the beam 4 and the joint piece 6. Locking hole 41
, 61 is also possible.
