DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor structure of an upper floor such as a second or third floor in a prefabricated house using a wooden panel construction method.

[0002]

2. Description of the Related Art Floor panels, wall panels,
In a prefabricated house constructed by assembling a roof panel or the like, a floor panel is connected to a lower surface of a rectangular plywood with a core material along a long side and a short side thereof, and is parallel to the long side. The core material is joined. And 1
Floor panels for floors are laid by placing short sides (and long sides on both sides of the room) on pedestals through foundations. Floor panels for second floors are walls on the first floor. The short side (and the long side for both sides of the room) is placed on the panel so that it can be laid.

[0003]

When the room on the first floor is large, the length of the floor panel for the second floor to be laid and laid on the wall panel is long, and the length of the floor panel is increased. In order to secure the rigidity, it is attempted to install a floor beam between the wall panels to support the long floor panel for the second floor from below, but if such a floor beam is provided, the ceiling of the first floor can be accommodated. It will have an effect.

Therefore, in the case of a long floor panel for the second floor, when the height of the core material is increased in order to increase the rigidity of the core material itself, it is necessary to prepare various height dimensions of the core material according to the panel length. Become. As described above, if the height of the core material is variously changed according to the panel length, the floor level changes for each room having a different size. In order to avoid such a problem, it is possible to cope with a floor panel having a core material that is thicker than a predetermined size by placing the floor panel on the wall panel via an adjusting material.

However, conversely, in the case of a floor panel for a second floor having a core material higher than a predetermined dimension, for example, cutting the upper end of the wall panel is not preferable in terms of securing rigidity. If the height of the core material of the floor panel for the floor is also set to the same height, the cost increases.
As described above, in particular, the 2 having the core material higher than the predetermined size is used.
In the case of floor panels for floors, it was difficult to make the floor level uniform with other rooms. Such a technical problem also applies to the floor panel for the third floor.

[0006] Therefore, an object of the present invention is to use a floor panel for a second floor or a third floor having a core material higher than a predetermined size as the length of the panel becomes longer, so that the floor panel on the lower floor is used. Another object of the present invention is to provide a floor structure on an upper floor in which the height of a short side portion or the like placed on a floor is shared so that the floor level can be equalized with other rooms.
