2. Description of the Related Art In order to increase the industrial production rate of a building, a room unit using a wall-type construction method has been conventionally known, for example, as described in Japanese Patent Publication No. 58-30978. The room unit by the wall-type construction method is constructed by erecting a wall panel on a side edge of a floor panel, and is produced in a factory in advance, and then constructed and assembled at a construction site to constitute a unit building. Assembly is performed by first installing the lower-floor room unit on the foundation, and then installing the upper-floor room unit on top of each of the installed lower-floor room units. By the way, the above-mentioned conventional room units did not have a ceiling per unit, so the installation work of the ceiling panel was done locally, and the electrical work and the construction work behind the ceiling were naturally done locally. The number of local construction man-hours was large. In order to improve this state, as shown in FIG. 10, wall panels 2a, 2a, 2b are erected on the side edges of the floor panel 1 in advance in a factory, and the upper parts of the wall panels 2a, 2a, 2b are further erected. Ceiling panel 3
(Japanese Patent Application No. 3-335 filed by the present applicant) has been proposed.

However, in the above-mentioned conventional room unit 4 with a ceiling, the ceiling panel 3 and the wall panels 2a, 2a, 2b are joined (joined portion).
However, as shown in the figure, since the configuration is such that the ceiling wins (the joint structure where the corner is occupied by the ceiling panel), the following inconvenience occurs. That is, the ceiling of each room in the unit building constituted by the above-mentioned conventional room unit with a ceiling is configured by connecting ceiling panels previously attached to each room unit. By the way, even if the installation height of the ceiling panel is correctly adjusted between the room units at the factory, when the room unit is actually installed at the construction site, the height difference between the ceiling panel and the ceiling panel of the adjacent room unit ( (Step difference between units). Since the step between the units of the ceiling panel is not limited to the step on the ceiling surface but also involves the step on the upper floor, it is necessary to adjust the height at the building site when the step between the units occurs. However, when the lower-floor room unit is the above-mentioned conventional room unit with a ceiling, the ceiling panel is sandwiched between the wall panel of the lower-floor room unit and the upper-floor room unit. It is very difficult to do.
