BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a unit building having a divided attic space.

[0002]

2. Description of the Related Art A unit building is disclosed in JP-A-55-3286.
As described in Japanese Patent Publication No. 3, a living room unit industrially manufactured in a factory in advance is transported to a building site, and a plurality of living room units are arranged adjacent to each other or stacked on a foundation provided in advance on the building site. It is constructed with a roof on top. Since there is an attic space between the living room unit and the roof, the space is effectively utilized as a compartment space called an attic storage room, a loft, an attic, or the like.

For example, Japanese Examined Patent Publication (Kokoku) No. 3-4700 discloses that
A factory-produced wall panel and ceiling panel are installed on the living room unit installed at the construction site, and a storage space is provided in the attic space between the living room unit and the roof. The structure is described. With this structure, a large panel is installed on the living room unit and assembled, which requires a great deal of construction man-hours. Also, the roofing process was done after the storage space was completed, and the construction period at the construction site of the unit building was prolonged.

However, in a unit building, a roof unit is adopted, and a hut or the like is also constructed in a factory to reduce the number of man-hours at a construction site. Therefore, the panel and the roof constituting the attic storage space are assembled as a roof unit at the factory, and the roof unit is installed on the living room unit at the construction site.
The unit building described in Japanese Patent No. 54636 was examined. This is to divide the attic space forming members that make up the attic storage room into the living room unit and the roof unit, respectively, and allocate them, and install the in-room unit and roof unit to complete the attic storage room. Is.

More specifically, a wooden frame, a wall board, a ceiling board, which constitute an attic storage room, are provided in a roof unit which is assembled into a shed.
Install the inner wall panel and heat insulating material. Also, the floor joists and floor boards that make up the attic storage room are attached to the ceiling of the living room unit. At the construction site, a roof unit is installed above the living room unit. Then, the storage space is divided from the attic space by the wall board, the ceiling board, the inner wall panel, and the floor board. Finally, joint construction between units will complete the attic storage room.

[0006]

However, the unit building described in Japanese Patent Laid-Open No. 4-254636 has the following problems. At the construction site, after installing the living room unit and before installing the roof unit, work such as waterproofing and indoor wiring may be performed on the ceiling of the living room unit, and when installing the roof unit. It was necessary for the instructor and the worker to get on the ceiling of the living room unit in order to modify the work instructions and the installation direction of the roof unit. For this reason, it is necessary to keep the floor board clean, which requires man-hours.

Further, at the construction site, it is necessary to connect the floor boards and the wall boards to all the peripheral edges of the floor boards, and thus it takes a lot of time to connect the attic space forming members. This connection work required man-hours after installing the roof unit when trying to finish the interior of the attic storage room neatly. Further, in order to finish this connection work from the inside of the attic storage room, it was necessary to bring the lighting into the attic storage room, and even if the roof unit was installed, it was not completed immediately.

Further, since each part of the attic space forming member is attached to the roof unit or the living room unit respectively, in the production line of the roof unit and the living room unit, the attaching process of the attic space forming member and the attic space are performed. Connection work between the space forming members was required, which did not contribute to improvement of production efficiency in the factory.
