(1) First Embodiment FIG. 1 is a perspective view showing a first embodiment of a building unit according to the present invention. FIG. 2 is an exploded perspective view showing the floor panel of FIG. 1 together with floor beams. FIG. 3 is a cross-sectional view of a part III in FIG. 1 and is a cross-sectional view showing a connection state with another floor panel.

A building unit 10 shown in FIG. 1 is a so-called wall-winning building unit which is arranged in such a manner that an end portion of a floor panel 12 is abutted against an inner surface of a wall panel 11 and has a substantially box shape. In this building unit 10, floor panels 12
The floor beam 13 is joined to the end of the wall panel 11 where no is disposed, and both ends of the floor beam 13 are attached to the wall panels 11 on both sides.

As shown in FIG. 2, the floor panel 12 has a plurality of floor joists 14 extending in the wife direction, and end joists 15 at both ends in the wife direction and side joists 16 at both ends in the girder direction. A floor framework is formed with each of them, and a floor surface material 17 and a lower surface material 18 (FIG. 3) are attached to the floor framework.

Although not shown, the wall panel 11 is provided with a plurality of vertical frames between an upper frame and a lower frame to form a wall frame set, and an outer wall material and an inner wall material are attached to the wall frame set. It is composed.

The floor beam 13 is made of C-shaped steel as shown in FIG. 3, and a web 21 of a floor receiving material 20 is fixed to the back surface of the web 19 of the floor beam 13.
The floor receiving member 20 is made of a Z-shaped steel or an L-shaped steel (in the figure, a Z-shaped steel is shown), and extends in the longitudinal direction of the floor beam 13. The web 21 of the floor support 20 and the web 19 of the floor beam 13 are fixed by welding or caulking. The end of the floor panel 12 is placed on the lower flange 25 of the floor support 20.

The floor support 20 is made of a wood screw 2 as a fixing means.
The floor beam 13 and the floor panel 12 are joined together by being fixed to the end of the floor panel 12 using 2 and 23. That is, the wood screws 22 penetrate the web 21 of the floor receiving member 20 and extend in the direction of the surface of the floor panel 12 (the floor member 17 and the lower surface member 18).
The floor support and the floor joists 14 and the end joists 15 of the floor panel 12 are fixed. Further, a wood screw 23 penetrating through the lower flange 25 of the floor support member 20 and extending in a direction perpendicular to the surface of the floor panel 12.

Therefore, the joint floor panel 30 needs to have a small area enough to cover the space between both floor beams 13. At this time, the joint floor surface material 30 is
0 is also supported by the upper flange 24.

Incidentally, reference numeral 31 in the drawing denotes a gypsum board.
According to the above embodiment, the following effects are obtained. Web 19 of floor beam 13 and web 2 of steel floor support 20
Since the surfaces 1 and 2 are fixed to each other, the welding area or the number of caulking points can be increased, and the rigidity of the floor beam 13 can be increased. Therefore, by fixing the floor beam 13 to the floor panel 12 using the wood screws 22 and 23, the structural strength of the floor panel 12 can be improved.

Further, a floor support member 20 fixed to the floor beam 13 is provided.
And the floor panel 12 penetrate the web 21 of the floor receiving material 20 and are fixed by wood screws 22 extending in the direction of the surface of the floor panel 12 (the floor surface material 17 and the lower surface material 18). The joint strength between the floor panel 12 and the floor beam 13 can be increased with respect to the load in the direction perpendicular to the plane.

Further, the floor support member 20 fixed to the floor beam 13
And the floor panel 12 are fixed by wood screws 23 that penetrate the lower flange 25 of the floor receiving member 20 and extend in a direction perpendicular to the surface of the floor panel 12 (the floor member 17 and the lower surface member 18). The joint strength between the floor panel 12 and the floor beam 13 can be increased with respect to the load in the plane direction of the floor panel 12 (for example, a pulling load).

The floor beam 13 integrated with the floor panel 12 of one building unit 10 and the floor beam 13 integrated with the floor panel 12 of another building unit 10 are connected to a joint plate 28 and joint bolts and nuts. 29, the floor panels 12 of both building units 10 are connected to each other.
2 can be easily and seamlessly connected.

Since the rigid floor beam 13 is joined to the floor panel 12, the building unit 10 with sufficient structural strength of the floor panel 12 can be realized.

Further, the floor panel 1 is provided on the inner surface of the wall panel 11.
2 were placed face-to-face, the floor panel 1
2 can be increased in thickness, and the sound insulation of floor impact noise can be improved.

Since the end of the floor panel 12 is arranged to abut the inner surface of the wall panel 11, the building unit 10
The ceiling height can be increased and the living space can be set large, despite the height of the ceiling being subject to transportation restrictions.
