FIG. 7 is a cross-sectional view showing a connection state between one floor panel and another floor panel.

The 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 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 FIGS. 2 and 3, 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 15 at both ends in the girder direction. Joist 16
, And a floor frame is formed, and a floor surface member 17 and a lower surface member 18 are attached to the floor frame.

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 joists 14 of the floor panel 12 are integrally formed with protrusions 20 at both ends. The floor panel 12
The end joist 15 is formed in a comb shape having a plurality of slits 21 as shown in FIGS. 3 and 4, and the slit 21 is opened at the lower surface 22 of the end joist 15. Accordingly, the connection between the floor joists 14 and the end joists 15 is performed by lowering the end joists 15 from above the protrusions 20 of the plurality of floor joists 14 and engaging the protrusions 20 with the slit portions 21 of the end joists 15. This is done by: In this way, floor joists 14
In the floor panel 12 configured by joining the floor joist 15 and the end joist 15, the protrusion 20 of the floor joist 14 projects from the end joist 15 below the floor panel 12.

5 and 6, the floor beam 13 is made of U-shaped steel. Inside the floor beam 13, a floor support 23 extends in the longitudinal direction of the floor beam 13. And is contained. The floor support 23 is made of a lip steel or a U-shaped steel (the lip steel is shown in the figure), and the floor beam 13 and the opening of the floor support 23 face each other. Housed within. The floor support 23 is fixed to the inner surface of the lower flange 24 of the floor beam 13 by welding.

The floor panel 1 is placed between the inner surface of the upper flange 25 of the floor beam 13 in which the floor support 23 is accommodated and the floor support 23.
2, the protrusion 20 of the floor joist 14 can be inserted.
With the protrusion 20 of the floor panel 12 inserted between the floor beam 13 and the floor support 23, the floor beam 13 is fixed to the protrusion 20 of the floor panel 12 using screws 26 and joined to the floor panel 12. Is done.

When a portion where the wall panel 11 of each floor panel 12 is not arranged is continuous between two building units 10 installed adjacent to each other, as shown in FIG. 12 integrated with the floor beam 1
3 are adjacent to each other. In other words, each of the floor beams 13 of the both floor panels 12 is connected to the lower flange 24 and the upper flange 25 of the floor beam 13 by using the joint plate 27 and the joint bolt / nut 28 as joining means.
At the sides, the floor panels 12 of both building units 10 are joined.

It is concealed by hanging over the floor surface material 17 of the panel 12 in a flush state. Therefore, the joint floor panel 29 needs to have a small area enough to cover the space between both floor beams 13.

According to the above embodiment, the following effects are obtained. A floor support 2 extending in the longitudinal direction of the floor beam 13 in the floor beam 13
Since the 3 is arranged, the rigidity of the floor beam 13 can be increased. The floor panel 12 has the structural strength improved by joining the floor beam to the end where the wall panel 11 is not disposed, but the floor beam 13 having increased rigidity as described above is fixed to the floor panel 12. Thereby, the structural strength of the floor panel 12 can be further improved.

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 27 and joint bolts and nuts. 28, the floor panels 12 of both building units 10 are joined together, so that the floor panels 1 of these building units 10 are joined together.
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.
