The column 6 is made of, for example, a square steel pipe, and the main beam 4 is made of, for example, an H-shaped steel. Note that the main frame 2 may be either pillar winning or beam winning. Basically, the foundation beam 3 and the main beam 4 extend parallel to each other so as to face each other in the vertical direction. That is, the foundation beam 3 and the main beam 4 extend in the same horizontal direction.

  The main body frame 2 includes auxiliary beams 5 passed between the main beams 4. Both ends of the auxiliary beam 5 are basically connected to the main beam 4, not the column 6, and are supported by the main beam 4. The installation location and number of the auxiliary beams 5 can be arbitrarily determined according to the layout of the building 1A and other needs. For the building 1A, the first floor will be described as an example. The auxiliary beam 5 is arranged at the center in the depth direction, and the longitudinal direction of the auxiliary beam 5 is the frontage direction Da that is the width direction of the frontage F in plan view. It is along. In addition, planar view means the state which looked at the building 1A from the perpendicular upper direction. Further, the auxiliary beam 5, the main beam 4, and the foundation beam 3 according to the present embodiment are one mode of the beam. Here, the main beam means a beam other than the outermost beam in each layer, a beam other than the beam whose end is connected to the middle of another beam, and the auxiliary beam is the other end of the beam. This is a beam connected to the middle part. In general, the auxiliary beam is in an arrangement relationship that is less likely to bear the horizontal force than the main beam. In addition, the auxiliary beam in the foundation beam may be made of steel in addition to concrete.

  The building 1 </ b> A includes an outer wall portion 8 provided on the outer periphery of the main body frame 2, a partition wall portion 9 that divides the space of each indoor room, and the like. The first floor portion of the building 1A is provided with an outer wall portion 8 along the auxiliary beam 5.
