DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ceiling structure at a connecting portion of a plurality of building units constituting a unit building.

[0002]

2. Description of the Related Art In recent years, unit-type buildings have been constructed in which a living room or the like constituting a building is manufactured as a building unit in a factory or the like, and these building units are transported to a construction site for construction. The building unit 1 includes, for example, four pillars 2 erected at four corners, as shown in FIG.
The two upper beams 3, 3 on the short side and the two upper beams 4, 4 on the long side, which are provided between the upper ends of the columns 2, and the lower ends of the columns 2. It is formed substantially in a box shape with a framework having four lower beams 5. A plurality of ceiling beams 6 are provided between the upper beams 3 on the long side in parallel at predetermined intervals.
A plurality of joists 7 are provided between the lower beams 4 on the long side in parallel at predetermined intervals. In addition, a ceiling plate 8, a floor plate 9, an inner wall, an outer wall (not shown), and the like are attached to such a frame. The ceiling material 8 is formed of, for example, a gypsum board, and is attached to the lower surface of the ceiling beams 6.

[0003] By the way, ceiling materials 8 are provided in advance in the building unit 1 in a factory or the like. When a plurality of the building units 1 are assembled to construct a unit-type house, adjacent building units 1 and 2 are installed. In one room, a connecting ceiling panel is retrofitted at the construction site.

[0004] As a mounting structure of such a connecting ceiling plate, for example, a technique described in Japanese Patent Application Laid-Open No. 4-22838 is known. In this technique, as shown in FIG. 4, at the connecting portions of the building units 1, 1 adjacent to each other, cutout steps 6a, 6a are formed on the lower surface at the ends of the ceiling beams 6, 6, and the cutout steps are formed. 6a, 6a are placed on the upper beams 4, 4 on the long side, and furthermore, the notch step 6a, 6a
10, a connecting ceiling plate 11 is provided between the ceiling wooden bars 10, 10, and the ends of the connecting ceiling plate 11 are connected to the ceiling wooden bars 10, 10 via spacers 12, 12. It was attached.

[0005]

By the way, the technique described in the above-mentioned Japanese Patent Application Laid-Open No. Hei 4-22838 discloses a method in which the building units 1, 1 adjacent to each other are connected between the upper beams 4, 4 on the long sides adjacent to each other. It is a technique for attaching the connecting ceiling plate 11, and the publication does not disclose a technique for attaching the connecting ceiling plate between the upper beams 3 on the short side. Since the above-mentioned ceiling beam 6 is not orthogonal to the upper beam 3 on the short side of the building unit 1 but is separated in parallel,
Using the above technique, the upper beams 3, 3 on the short side adjacent to each other
No tiling ceiling panels can be installed between them.

Therefore, it is conceivable to attach the end of the connecting ceiling plate to the ceiling beam 6 located closest to the upper beam 3 on the shorter side. Ceiling beam 6 closest to upper beam 3 on the short side
And the ceiling beam 6 closest to the upper beam 3 on the short side of the other building unit 1 becomes relatively long, so that the connecting ceiling plate also becomes large according to this distance, Since the connecting ceiling panel becomes large, it is difficult to handle the large connecting ceiling panel at a construction site.
