[0002]

2. Description of the Related Art Floor panels made of wood panels, wall panels,
In a wooden prefabricated building constructed by assembling roof panels and the like, wall panels are joined and integrated by interposing vertical and horizontal cores between the front and back plywood, and floor panels and roof panels are the lower surface of the front plywood. The core material is joined and integrated.

In a two-story or three-story house, the horizontal floor distance between the second or third floor and the roof ridge is a prescribed value (for example, 4.5 m). There are plans that go beyond, a plan with a steep roof, and a plan with a stairwell.

[0004]

However, as described above, in the case of a plan in which the distance between horizontal framing surfaces exceeds a specified value, the roof has a steep slope, or there is a stairwell, securing the strength of the building is a problem. Become.

Therefore, an object of the present invention is to construct a wooden prefabricated building using a wooden panel construction method, for example, when the distance between horizontal construction surfaces exceeds a specified value, the roof has a steep slope, or there is a stairwell. Is to ensure the strength of.

[0006]

In order to solve the above problems, the present invention is directed to an upper part of a room in a wooden prefabricated building in which a roof panel is assembled on a wooden wall panel.
The inner surface of the wall panel and either the lower surface of the roof panel or the inner surface of the other wall panel are connected by a plane frame with a frame structure of vertical and horizontal cross members to provide an auxiliary structure. Characterize.

The auxiliary structure is a horizontal structure that is joined to the wall panel at a right angle. In addition, the auxiliary structure,
It is an inclined structure that is diagonally joined to the wall panel.

[0008]

[Operation] For example, if the distance between horizontal structures exceeds the specified value,
If you have a steep roof or a stairwell,
Between the inner surface of the wall panel and either the lower surface of the roof panel or the inner surface of the other wall panel, we have connected a plane frame with the frame structure of the horizontal and vertical cross members so that it joins at right angles to the wall panel. The horizontal structure or the inclined structure that is diagonally joined together serves as an auxiliary structure, and the auxiliary structure ensures the strength of the building.
