Since the moment length from the ceiling beam 16 on the outer side of the unit 12B to the one ceiling beam 16 on the main unit 12A is longer, the eaves forming beam provided on the outer side of the building extension beam 30 When a load is applied to 32, the load applied to the ceiling beam 16 on the building outer side of the half unit 12B can be further reduced. Thereby, since the load-bearing structure of the ceiling beam 16 of the building unit 12 by deepening the eaves 82 can be simplified, the cost can be further suppressed.

  Further, the eaves extension beam 30 is arranged such that one end 34 in the longitudinal direction corresponds to one of the ceiling beams 16 of the building unit 12 and the other end 36 in the longitudinal direction of the eaves extension beam 30 is the building unit. However, the present invention is not limited to this, and the one end 34 in the longitudinal direction is arranged at a position corresponding to a portion other than the one ceiling girder 16 of the building unit 12. It may be. That is, by arranging one end 34 in the longitudinal direction of the eaves extension beam 30 on the outer side of the building unit 12, the eaves extension beam 30 has a deep eaves on the side opposite to the other end 36 in the longitudinal direction. It is good also as a structure which forms.
