Even if connected, the building unit 1 is reinforced so that the connection can be fixed stably. In addition, although not shown, it is preferable that the lower beam of the building unit 1 also reinforces the building unit 1 by welding and fixing the attachment attachment for the same structure and connecting the small floor beam between the lower beams as an auxiliary beam. .

 In addition, in another embodiment shown in FIG. 27, the building unit 1 which connects the auxiliary unit 10D is reinforced by the auxiliary beam 52A and the intermediate | middle pillar 45A as a reinforcement member. The auxiliary beam 52A of this example is similarly formed of C-beams, and the intermediate column 45A is also formed of C-beams. And the joining attachment 51A for connecting the auxiliary beam 52A is a shape which cut | disconnected the C-beam in the same direction as the upper beam 5, and is similar to the attachment 51 mentioned above to the upper beam 5 Welded The auxiliary beam 52A is connected between the upper beams 5 and 5 by means of the bolt 56 and the nut 53 through the attachments 51A and 51A. In addition, an intermediate pillar 45A is connected between the upper beam 5 and the lower beam (not shown) so that the building unit 1 is reinforced. In the building unit 1 of this embodiment, since the upper beam 5 and the lower beam of the portion connecting the short unit units 10D are reinforced by the auxiliary beam 52A and the intermediate column 45A. The connection part of the building unit 1 is stabilized.

The auxiliary unit 10H which is an auxiliary structure of another embodiment shown in FIG. 28 is configured as a balcony unit. This auxiliary unit 10H connects the lower ends of the two pillars 11 and 11 to the lower beam 12 and the upper ends to the upper beam 14, as shown in Fig. 28 (b). A wing frame F1 connected thereto, a wing frame on the opposite side (not shown), and a bottom frame F2 welded to the lower beams 13 and 13 and a floor joist, and an upper beam 15, The rectangular frame of the rectangular parallelepiped is comprised by connecting the ceiling frame F3 which welded 15 and the ceiling line with a bolt nut etc. through the joint plate similar to the above.

Wing frame F1 is not shown in detail, but similarly to the above embodiment, one of the lower beam 12 and the upper beam 14 is rigidly joined to the pillars 11 and 11 by welding, and the other It is connected to the pillar materials 11 and 11 by a bolt nut. Alternatively, both the lower beam 12 and the upper beam 14 are connected to the pillar materials 11 and 11 by bolt nuts. Moreover, the balcony railing 18 is connected and fixed through the joint plate J1 at the interruption of the long side direction at the edge of an eaves. Thus, the upper surface, the lower surface, and both side surfaces of the rectangular parallelepiped consisting of a plurality of frames are covered with an outer wall material (not shown) to form the auxiliary unit 10H.

The auxiliary unit 10H of this example is connected to and fixed to the pillar materials 2 and 2 which are members constituting one elevation of the building unit 1, and is bolted to the installation hole 30 in the same manner as in the above embodiment.
