The floor 2 includes a side joist 5, an end joist 6 and a plurality of intermediate joists 7 interposed therebetween, and an upper surface of a floor framework 2a.
It is configured by installing.

Further, the wall 3 is obtained by attaching a face material 12 made of gypsum board, wood chip cement or the like to the inner and outer surfaces of the wall frame assembly 3a, in which an upper frame 9, a lower frame 10 and a plurality of vertical frames 11 are assembled. It is configured.

Further, 13 is an assembled beam, in which an upper flange 14 and a lower flange 15 are connected to each other through a plurality of stiffeners 16, and the upper flange 14 and the lower flange 15 are provided on both side surfaces thereof. A face material web 17 is attached and the whole is integrally connected. As is apparent from the drawing, the assembly beam 13 is connected and integrally attached over the entire length in the finding direction above the wall 3 on at least one surface of the wooden house unit.

When the assembly beam 13 is incorporated in the wall 3 as described above, as shown in FIG.
The face material 12 of the wall 3 is laminated on the inner and outer surfaces of the.
When the assembled beam 13 is not incorporated in the wall 3,
As shown in FIG. 2 (B), the face material 12 is not laminated on the web 17 of the assembly beam 13.

The ceiling 4 is the upper flange 1 of the assembled beam 12.
The ceiling board 19 is attached to the ceiling frame assembly 4a, which is composed of 3 and a plurality of field edge members 18 that are suspended inside the rectangular frame surrounded by these upper flanges 13.

The lengthwise and widthwise dimensions of the wooden house unit 1 according to the present invention are constructed on the basis of a positive multiple of a fixed module (for example, 455 mm). The width of the above-mentioned assembled beam 13 is determined by the width of the upper and lower flanges 14 and 15. That is, as shown in FIGS. 2 (A) and 2 (B),
By adjusting the width of the upper and lower flanges 14 and 15, the width of the assembled beam 13 can be changed. Also,
By adjusting the width of the assembled beam 13 in this manner, the assembled beam 13 can be housed in the wall 3 as shown in FIG. 2 (A).

The assembled beam 13 used in the present invention.
As described above, since the upper and lower flanges 14 and 15 are connected to each other through the plurality of stiffeners 16 and the webs 17 are attached to both side surfaces of the upper and lower flanges 14 and 15, the beams have a large beam structure. are doing. Therefore, the structural performance of the assembled beam 13 should be extremely superior to that of the laminated wood, as is clear from the "comparison table of the assembled beam and the laminated wood" in the following table. Is clear.

[0018]

That is, as shown in the above table, the assembled beam 13 has a cross-sectional area (207.80 cm ² ) almost the same as the cross-sectional area (209.15 cm ² ) of the laminated material, but the second moment of area is It is clear that it has about 11 times the performance of wood.

Moreover, this assembled beam 13 can be mass-produced in advance in a factory or the like with high accuracy and at low cost. Moreover, the assembled beam 13 can be divided and transported, and can be easily combined into a beam with a long span by on-site construction. Further, since the assembled beam 13 used in the present invention is connected to the upper portion of the wall (bearing wall) 3 as described above, even when the building receives a horizontal force such as an earthquake load or a wind load, By the effect of bending back, the wall 3 can be prevented from rising.
