FIG. 9A is a side view showing the floor of the unit bath and the floor support structure in the present embodiment, and FIG. 9B is a partially enlarged plan sectional view showing the positional relationship between the unit bath and the housing outer wall in the present embodiment. FIG. In addition, in FIG. 8A-FIG. 9B, the bathtub is not illustrated.

  Conventionally, a unit bath is attached to a building structure constituting a house (building) at a building site. In this case, if the design dimensions of the unit bath and the design dimensions of the building structure are strictly matched, the manufacturing error of the unit bus or the displacement of the building structure itself (such as misalignment between building materials or distortion of building materials) ) May cause problems such as inability to attach the unit bus to the building structure at the construction site. For this reason, the unit bath and the building structure are designed with a certain margin (margin).

  For this reason, the conventional unit bus can be adjusted on the spot in the vertical direction (vertical direction) and the horizontal direction when it is attached to the building structure at the construction site.

  For example, as shown in FIG. 8A, in the conventional unit bus 32X, the vertical position (height) of the unit bus 32X can be adjusted at the time of construction at a construction site, so that it can be adjusted behind the floor (floor pan) 32a. Are provided with a plurality of height adjusting bolts 32c. The adjuster bolt 32c is attached to a house building structure (such as joists or beams). That is, the conventional unit bus 32X is installed in the building structure via the adjuster bolt 32c. Since the adjuster bolt 32c is provided in this manner, the height of the floor 32a can be changed, so that the vertical position of the unit bath 32X can be adjusted at the construction site.

  Further, in the conventional unit bus 32X, as shown in FIG. 8B, there is a certain gap (for example, about 100 mm) between the wall panel 32b constituting the four side surfaces of the unit bus 32X and the outer wall of the house. Designed to exist in position. As a result, when the unit bus 32X is installed at the construction site, even if a horizontal displacement has occurred in the building structure, the horizontal displacement of the unit bus 32X can be adjusted. Can be absorbed.

  On the other hand, in the building unit 1 in the present embodiment, as shown in FIG. 9A, the unit bus 32 is not provided with an adjuster bolt, and the floor 32a is directly placed on the building structure 12a. Specifically, the floor 32a is placed on the beam 12a1 of the building structure 12a.

  In the present embodiment, since the unit bus 32 is incorporated in the building structure 12a of the second unit 12 in advance in the factory, the unit bus 32 and the building structure 12a are assembled with high accuracy and high quality. Therefore, it is not necessary to adjust the position of the height of the unit bus 32 with respect to the building structure 12a at the building site, so that it is not necessary to use an adjuster bolt.

  Thus, since the adjuster bolt is not used in the building unit 1 in the present embodiment, the number of parts can be reduced as compared with the conventional unit bus 32X.

  Moreover, in the building unit 1 in this Embodiment, as shown to FIG. 9B, the wall panel (bathroom wall) 32b which comprises 4 side surfaces of the unit bath 32 is directly joined to the wall of the 2nd unit 12. As shown in FIG. . Specifically, the wall panel 32 b is directly joined to the surface of the wall base material 13 constituting the inner wall of the second unit 12.

  The wall panel 32b and the wall base material 13 can be directly joined by bonding together with an adhesive, for example. Further, the bonding between the wall panel 32b and the wall base material 13 is not limited to the adhesive, and may be performed by screws, bolts and nuts.

  As described above, since the unit bus 32 is built in the building structure 12a of the second unit 12 in advance at the factory, the unit bus 32 and the building structure 12a are assembled with high accuracy and high quality. Therefore, there is no need to adjust the horizontal position of the unit bus 32 with respect to the wall or building structure of the house at the building site, so there is no gap between the wall panel 32b and the wall of the house as in the conventional unit bus 32X. There is no need to provide.
