Available.

[0002]

2. Description of the Related Art Conventionally, unit buildings that are frequently used for building buildings such as houses are manufactured in advance at a factory or the like to produce a plurality of substantially box-shaped building units in order to reduce construction costs.
These building units are transported by a truck or the like and are arranged and stacked at a construction site to be constructed.
The building unit is produced by attaching an interior material, an exterior material, and the like to a frame having a substantially box-shaped frame structure including a plurality of columns, connections, beams, and the like. Such a building unit has an outer dimension that fits inside a maximum height dimension and a maximum width dimension predetermined by law or the like when stacked on a truck bed.

In recent years, it has been attempted to form a garage inside a building by using the above-described building unit. However, when a car is put in and out, a lower beam constituting a frame becomes an obstacle. An ingenuity is being attempted. For example, in the garage building unit 60A shown in FIG.
A garage floor 62 for mounting the garage is formed above the lower beam 64 of the frame 63, and a slope 65 continuous with the garage floor 62 is provided for on-site work. On the other hand, in the garage building unit 60B shown in FIG.
Is formed so as to be continuous with the site, and a lower beam 64 to be disposed at a portion where the car 61 enters and exits is removed.

However, in the garage building unit 60A,
Since it is necessary to provide the slope 65 at the construction site, the work on site increases, and when the site in front of the garage is narrow, the slope 65 becomes steep and it is difficult to put the vehicle 61 in and out. On the other hand, in the garage building unit 60B, since the lower beam 64 of the frame 63 is removed, there is a problem that the strength is insufficient. On the other hand, like the garage building unit 60C shown in FIG. 6 (C), the lower beam 64 is buried in the premises and is adjacent to another building unit 60 on the same floor, which is a normal arrangement. It is conceivable to arrange them in steps.

[Problems to be solved by the invention]

When the garage building unit 60C as described above is stepped, the upper surface position of the garage building unit 60C is different from the upper surface position of the normally arranged building unit 60. It is necessary to take measures so as not to affect the stacking arrangement of other building units (not shown) for use. For such a problem, the garage building unit 60C
As a method, a method using a building unit (commonly referred to as a floor height unit) having a larger height than usual is considered.

However, since the height unit of the floor-height unit is larger than that of a normal building unit, it is necessary to use a dedicated low-floor truck which does not violate transportation restrictions in order to transport it to the construction site. Yes, the transportation cost increases. The floor-height unit has a problem that the construction cost is high because the outer dimensions are different from those of the normal building unit, and thus the construction cost is high .

An object of the present invention is to provide a building unit height adjusting structure capable of reducing the construction cost of a unit building having a garage .

[0008]

The outer wall 22 is attached to the height adjusting member 20 and the outer wall auxiliary member 43. In addition, the outer wall 22 is attached to the upper beam 17 of the garage building unit 14 and the lower beam of the upper floor building unit 12. The height dimension of the outer wall to be mounted via predetermined hardware or the like, or to be attached to the garage building unit 14 or the upper floor building unit 12, is set to be large in advance, and the extra space covers the step space 21. You may. The outer wall auxiliary member 43 is not essential to the present invention, and may be omitted as appropriate.

The height adjusting member as described above does not need to be connected to all the columns of the building unit.
In the case of a flat regular hexagonal building unit provided with columns, the height adjusting member may be connected only to arbitrary columns. Also, the height dimensions of each height adjustment member may be different from each other, for example, when one or both of the upper surface of a building unit such as a garage building unit and the lower surface of an upper floor building unit are inclined. What is necessary is just to connect each thing with a different height dimension to each pillar.
